  • Do You Understand This Emerging Technology By Building A Dynamic Wiring System With Programmable Matter?

    The construction of dynamic wiring systems by programmable matter is a relatively emerging technology direction at present. Many people are confused about what this technology is, can be used for it, and whether it has practical use, and even think it is an unrealistic gimmick. Simply put, programmable substances are like "brained" materials. They can change shapes, structures, or certain physical characteristics according to preset program instructions or signals provided by us in real time. To put it bluntly, the wires and lines can adjust their directions and connection relationships by themselves like living things. Without having to work hard to manually change the line layout and those troublesome things… These two can be combined to create a new wiring method that can change itself, which may be of great use in many places.

    1. Material characteristics and basic composition : The programmable substances that make up dynamic wiring are not ordinary, not ordinary materials that we usually see. It must have many tiny basic units with some intelligence inside, just like small robot bricks. These small units must also be able to "talk" and "cooperate" with each other. This is the case, the ability to work together is particularly important. Moreover, each small unit must have some ability to conduct itself, otherwise how can it transmit signals and electricity? Otherwise, it would be in vain? Therefore, when choosing materials, you must have good performance and be able to deform, so that you can flexibly adjust

    2. The core implementation steps of dynamic reconstruction : To make the wiring dynamic, the steps are not simple, you have to take it step by step and be orderly. Step 1: First there must be a (central management system), which is like a band commander, responsible for issuing orders. How do you want to arrange the line and tell it, it will start to think and calculate. Step 2: After receiving the instructions sent by the above, those programmable material units will start to move, and connect them (run to the place you should be in line to stand up). If this process goes wrong, it will be troublesome, so the error mechanism must be good! * Step 3: After combining, it must be able to withstand loneliness and work stably for a period of time, but when there is something to do, it must be able to quickly "change mind" and switch to a new connection (a configuration mode, probably this means), and respond quickly! Also, if a small unit breaks in the middle, the others can be replaced and "fixed" quickly. This is called intelligence.

    Provide global procurement services for weak current intelligent products!

    3. Appearance of application and actual advantages : It is not that this thing is useless, but in fact it can be useful in many places and solve many old problems. For example, the experimental places that often need to be modified, such as scientific research labs and electronic development (the meaning of the work area), before wiring modification was like a war, which was time-consuming and expensive; with this dynamic wiring, you can do it with just a click of the mouse, which is simply too labor-saving and time-consuming! There is also the kind of production line. Today, the machine may be working here, but the day after tomorrow, it will be moved to the other side. How troublesome is the line running around? Use it and make a quick swipe and arrange the route yourself! The space utilization will be particularly effective. The efficiency will be greatly improved, and there will be much less messy wires and waste!

    4. Summary of simple answers to common questions : Everyone always likes to ask some duplicate questions that everyone cares about. Here we will answer the questions in a unified way. > Q: Will this thing be particularly power- (power-consuming)? It won't take a while before the power goes out? A: Now researchers are trying to optimize, and new materials are constantly coming out, with the goal of low power consumption! Small units will also "discuss" themselves to reduce unnecessary movements and save some electricity, so it is generally not a problem to use them for half a day. It depends on how you use them and where you use them. > Q: Compared with traditional (manual wiring), is it really so much better? Is there any place that is actually not as useful as the old method? A: The advantages of simple connection scenarios are not particularly large, and the cost may even be a bit expensive. But in the face of an environment that changes all day long, or a closed space where the route is particularly complex and there is no place for people to take action, the benefits it brings, such as reducing manual errors and improving efficiency, are not a small matter.

    5. Points to pay attention to in future development : There are always areas where continuous progress is needed for technological development and new possibilities will emerge! Safety must be strengthened. The lines themselves change, and the short circuit and tripping of the unconnected connections cannot happen. Also, how to "get along" and be compatible with us (the existing messy systems) is also a big problem! I hope that the cost will be lower and lower in the future, so that more companies and industries can use it. At that time, the problem of wires running around in every household may be solved! My personal opinion is that although programmable material dynamic wiring may still have some small flaws and is not promoted so quickly, in the long run, it is definitely a very promising and highly valued development direction in wiring technology, with huge potential!

  • In The New Office Environment, How Can Video Conferencing Be Smooth, Clear And Efficient?

    In today's new office environment where everyone cannot do without the Internet and must hold meetings and communication frequently, how to do video conferencing to be smooth and clear and can truly improve work efficiency is indeed a difficult task that many compatriots in the workplace have to think about every day! The so-called video conferencing is simply a way to communicate through network technology that allows people in different places to see each other's images, hear each other's voices in real time, and even read files and modify things together. Now, whether it is a company holding a cross-department conference, finalizing contract details with outside customers, or even school giving students online classes, it is necessary to use it; it can be said that it is like an important link that cannot be missing in our daily office life, closely connecting people scattered everywhere in work and study.

    1. What are the secrets for pre-use equipment and network preparation? At least buy a computer with a high-definition camera. Now the one on the market has a pixel reaching 1080P is pretty good! For microphones, it is best not to use any kind of slack products for a few dozen dollars. The entire noise reduction effect is better or the desktop is placed on the desktop. Otherwise, there will be a noise during the meeting and people can't hear what you are saying. In terms of the network, a wired network is definitely much more stable than a wireless network. If you really can't use a wireless network, then you have to be closer to the router and disconnect the things that occupy the network speed of your phone first to ensure that the upload and download speeds can be stable at more than 2 megabytes per second… That's right, we provide global procurement services for weak current intelligent products! Maybe you can buy any equipment on this website, it's quite convenient

    2. What are the operating skills during the meeting? Before entering the meeting, you have to open the software about ten minutes in advance to check whether the camera angle is right, whether it can just take a picture of your face and upper body clearly, and don’t just show the top of your head or half of your face; remember to turn it on when it’s your turn to speak, and close it quickly after you finish speaking, otherwise you will cough or whisper to the people next to you, and everyone in the venue will hear it clearly, which is so embarrassing. There is also a screen sharing function. When you want to use this function, turn off all the messy files on the desktop in advance, leaving only the window to show everyone, so as to avoid accidentally giving private files to others…

    3. Tips for improving the effectiveness of the meeting and participants? Before speaking, raise your hand or signal to the host. Don’t rush to say it all over the place, that won’t be a vegetable market! You should speak closely around the topic of the conference discussion, and don’t talk about things that have nothing to do with the conference, which will waste everyone’s precious time; important places can be recorded in the chat box provided by the software at any time, or use notes to write them on the notebook. Now many video conferencing software also have a real-time subtitle function. If you turn on that function, if you can’t hear it clearly, you can understand what it means when you look at the subtitles…

    4. How to solve the problem if an emergency occurs? If the screen suddenly gets stuck and cannot move, or the sound is intermittent and cannot be heard clearly, don’t panic first. The first step is to check whether your network connection is good, or simply turn off the conference software and log in again to try it. If it still doesn’t work, you can quickly call the host to explain the situation with your mobile phone, or send a message in the conference group to tell you that there is something small problem here, and you will find a way to solve it as soon as possible…

    5. How to compare and select common software? Like Zoom, the system runs very fast and the video quality is very high. It can support up to 1,000 people to have meetings at the same time. However, some of its advanced features are available only in the paid version! Tencent Meeting is very friendly to our domestic users. The operating interface is very simple and you can see it at a glance. The basic functions are free for everyone to use. They can also be directly connected to WeChat and QQ, which is particularly convenient. In addition to the function of video conferences, DingTalk also has many office-related functions. If the company originally uses DingTalk to manage work, it will be easier to use it at the same time…

    Q: What should I do when someone suddenly spoke loudly next to me and disturbed the meeting? Answer: At this time, you can turn off your microphone quickly, then wave your hand gently to him, and whisper to him, "I'm holding an important meeting, please feel a little bit lower, OK?" After you settle him, turn on the microphone and secretly say sorry to the people in the meeting. This will not only solve the problem, but will not interrupt the meeting for too long! Q: What is the use of the conference recording function? Answer: If some colleagues cannot attend the meeting because of other urgent matters, they can watch and playback themselves after recording it and make up for the content of the meeting. And sometimes, the important instructions given by the leaders at the meeting or the key decisions discussed by everyone can be recorded as evidence or reference in the future, so as not to forget who said what he said at that time…

    I personally think that although video conferencing sometimes feels very annoying due to poor network or equipment problems, as long as you master these small methods and tips and do the preparations in advance, it can still bring great convenience to our work and study, saving a lot of time to travel and the cost of running back and forth! So everyone must take every video conference seriously and use these things they have learned well

  • What Is A Dynamic Content Management System? What's Better Than Static Web Pages? Let Me Tell You

    , which is what we often call a dynamic content management system. This thing is really a core thing for building websites or mini programs now! Many people may not quite understand what this dynamic content management system is? Compared with those stupid and motionless static web pages, what's better? Don't worry, I'll talk to you slowly, I'll make sure you can hear it clearly! Provide global procurement services for weak current intelligent products!

    At the beginning, I have to briefly explain this basic concept to everyone: This – – Alas, it's too hard to say that the full name is D-CMS! It's not the old antique system that is nailed there after writing things. It is like a super administrator. The backend can manage all the messy content such as text, pictures, and videos in an orderly manner. The most amazing thing is that no matter when the user watches it in the front desk, the content they see can change in real time according to different situations! For example, if you log in today and tomorrow, and look at the same page, the things that may come out may be different. This is called "dynamic". Do you understand?

    Let’s talk about the key contents in this D-CMS, and then break them down and say one by one:

    1. Separate content from display: This is definitely the unique skill of D-CMS! In the past, when we made web pages, the content was written directly in the code. If we changed a small typo, we had to read the code for a long time. Isn’t it annoying? Now, D-CMS clearly distinguishes the "meat" of text, pictures, and the "skeleton" of page layout and style – the content is properly stored in the database, and then it is called according to the template when displayed. In this way, writers can just concentrate on writing content, and don’t have to worry about HTML or CSS at all, so you can save more worry! If you are designing, you can also do whatever you want to see if the page looks good and will not delay content updates.

    2. Super powerful user permission management module: It is impossible for a website or system to use it alone? There are administrators, editors, publishers, and perhaps even reviewers… This D-CMS can set different "powers" for different people! For example, the editor can only write, modify, submit and other reviews, but cannot publish them directly; the auditor just checks whether it is possible, or pass or call back; only the boss-level administrator has the right to finally nod and publish, or even delete things – in this way, the team can be free from messing around and very safe!

    3. Template engine function that is extremely flexible: If you want to talk about why this D-CMS can make fancy and different pages, this template engine can make great contributions! You think that by making various templates in advance, such as the templates of the news list, the templates of the details page, and the templates of the product display… as soon as you stuff them in, you can generate many pages! Moreover, the template can be changed at any time. Today I want to make a festive red tone, and tomorrow I want to change a fresh blue tone. You can basically do it with a few clicks of the mouse. You don’t have to rework it from beginning to end, which is a big deal!

    4. Built-in workflow mechanism: Friends who have written articles and sent messages must know that from writing an article to the end of the article, there are a few twists and turns in the middle, right? Sometimes you have to modify it yourself a few times first, then show it to the leader. The leader says it is OK, and then type it by a specialist, and finally send it out. D-CMS can turn this set of procedures into an automated process chain! Who should do each step, which step you go back to, and remind who if you do it wrong… you can set it all well, and if you are smooth, you will not be prone to make mistakes or missed steps.

    5 personalized content recommendation engines : This is so important, and now we don’t pay attention to “precise feeding”! D-CMS can secretly analyze users' preferences based on a variety of data such as who is visiting, what has been seen, where is it, what equipment it is used, and what equipment it is using. Then? I recommend something that he may be interested in to this person and another one to that person. This will make everyone feel that the website is particularly "confronted with the temper" of themselves, so I am naturally willing to stay for a while. Maybe I can read a few more pages, but the effect will be improved?

    Okay, the key points are almost done. I guess some people still have some small questions in their minds. So let’s use the Q&A form to add some details, and then emphasize the knowledge of practical things and key points to avoid pitfalls:

    Q: I am just a small broken company and no one can read the website. Is it necessary to use such a high-level D-CMS? It's almost done with a free blog system

    Answer: Alas, this is not right! Don't underestimate this D-CMS, it's not that only large companies can use it. Many D-CMSs now have small and medium-sized enterprise versions, and even have free and open source, which are sufficient for functions. You think, even if the business is small now and there are more content and more people in the future, do you still have to throw away the old ones and replace them with a new one? That would be so troublesome and expensive! Use D-CMS early to lay the foundation, and it will be convenient to add functions and expand them in the future! Moreover, compared with professional D-CMS, the gap between security performance and collaborative work ability is quite large. Don’t save a small amount of money and regret spending a lot of money in the future.

    Q: When choosing D-CMS, what should you pay attention to most? Are there any "pits" to avoid? Answer: This question is so real! First of all, we must see whether it is open source or whether its API interface is very rich and looks like ! There are many people using open source systems, and all the problems are exposed and fixed. There is no need to worry about the manufacturer not updating in the future. The API interface is not good, and it will be difficult to connect it with other systems, such as membership systems and e-commerce order systems in the future! Second, see if it is search engine friendly or not. Now that we are building websites, who doesn’t want to be searched in front of Baidu and Google? Is the page link structure generated by D-CMS clear, can you customize the title description, and the website opening speed fast… These directly affect the search ranking! The third one is money! Some people look at the free D-CMS, but after using it, they find that if you want to add some advanced features, you have to pay for plug-ins. The sum may be more expensive than buying a paid one directly! So from the beginning, you have to understand the costs and regulations of free or paid, and don’t be fooled!

    I've been talking for so long, but I'm actually trying to tell you that this is not a remote high-tech. It's just a capable assistant who can help us do our work quickly and well, and can also make websites or applications "live"! If you choose the right or use it well, the experience will be rising rapidly for those who manage content or for ordinary users who read content! So, if you are still messing with content in an old way, you can really consider thinking about this D-CMS, it will definitely not be a loss!

  • What Is A Floating Urban Infrastructure Suite? What's The Use? Is It Reliable?

    Floating urban infrastructure suite, this thing is being mentioned more and more now. Many people want to know what it is, how to use it, and whether it is reliable! Simply put, it is a set of equipment and materials that can allow the city to float on the water and run normally. It is like building blocks, but it is much more complicated than building blocks! It is mainly to solve the problem of not enough land, or to avoid the troubles of floods, and it is new. Next, I will tell you some of the key and real things here, which are guaranteed to be dry and hard-working, and there is nothing stupid!

    First of all, we have to talk about this floating body foundation module . This is the foundation of the entire kit, which is equivalent to the foundation of the building. Do you think it is important? Without a solid floating body, nothing is used to make it! There are several common types on the market:

    1. ♦ High-density polyethylene (HDPE) floating box, this thing is lightweight and corrosion-resistant, with a single buoyancy ranging from several hundred kilograms to several tons or dozens of tons. It depends on how much load-bearing you need. If the project is small, just put together a few pieces and install them easily.

    2. ♦ Concrete floating platform, uh, this one is heavy, but it is safe! It also has a large bearing capacity and is suitable for heavy work, but it has to be used for transportation and installation.

    3. ♦ Some places also use steel or composite materials, each with its own benefits and troubles.

    Then, there is the water building structural system . It’s not enough to have floats alone, but you have to build a house on it, right? The materials used must also be particular, not too heavy, and must be strong and corrosion-resistant. For example, if light steel keel is matched with lightweight wall panels, or aluminum alloy structures, or even some advanced ones use carbon fiber composite materials, the cost will increase! The connection method is also very special. It is not the kind of head-on collision on the ground. You need to get some moving joints to adapt to the unhonest shaking in the water. For example, hinge connections and rubber cushioning must be used. Provide global procurement services for weak current intelligent products!

    Let’s talk about it further, energy supply and freshwater systems are also inseparable. What should I do if I don’t have water or electricity? The most common one is solar panels. The water is large and there are many places that can be sunbathed, which is cost-effective to install. Some will also be equipped with a small wind energy device, which can be used in mixed wind and solar energy, and have a safe point. Freshwater mainly depends on seawater desalination equipment or rainwater collection and treatment systems. This cost is not low, so it needs to be calculated carefully.

    Also, can the modular package of communication and weak current systems be separated from the Internet now? Definitely not possible! Therefore, this kit generally also includes a waterproof communication base station installation platform, an underwater optical cable or a reserved interface for wireless access equipment. It is necessary to ensure that the signals on and under the water are unobstructed, and monitoring and data transmission cannot be lost. When purchasing these equipment, special requirements such as waterproofing and salt spray corrosion resistance must also be considered.

    Then use the form of questions and answers to add some details to everyone to avoid any questions:

    Q: How long will this kit last? Isn't daily maintenance very troublesome?

    A: Generally speaking, better floating materials can be used for 15-25 years, but it depends on the quality of the material and the environment used. Seawater is much more corrosive than freshwater. Maintenance is definitely more troublesome than building on the ground. Regularly check whether the floating body is damaged, whether the connecting parts are tight, and whether the anti-rust coating is lost or not, all of which need to be done.

    Q: The hydrological conditions in different regions are different. Can this kit be used casually?

    A: You have to look forward to this in advance! The wave height, water flow speed, and water depth are different in different places, and the design parameters of the kit must also change. Some kits are modular and adjustable, but they are not omnipotent. If you can’t buy one, you want to use it all over the world. That’s impossible!

    Q: Compared to building cities on land, how much is this floating kit expensive?

    A: The initial investment specification is much more expensive, especially when the technology is not yet mature. But if you are in places where land is so expensive that it is scary or is always flooded, it will be a little more cost-effective to calculate it for a long time, and it depends on the specific situation.

    If you ask me your personal opinion, this floating urban infrastructure suite has prospects, and solving specific problems is indeed an idea. But technically, the cost must be further reduced, and the supporting policies and regulations must also keep up, otherwise it will be difficult to promote!

  • Explore Neom's Smart City Technology: What Exactly Is It? How To Change Your Life?

    In recent years, more and more people have paid attention to Neom's smart city technology. After all, everyone wants to know what kind of black technology should be used to change our lives this sounding super powerful city of the future! You want to ask me what this Neom smart city is? Simply put, it is just a bunch of particularly advanced and intelligent technologies that bring together. I want to build a brand new city into an amazing place that is both environmentally friendly, efficient and particularly livable. It is not a casual talk!

    What is Neom smart city technology? It is not a single technology, but a comprehensive technology system that connects many aspects like the Internet. For example;

    1. Digital infrastructure planned from scratch is as important as the blood vessels of a city. Without it, no intelligence is mentioned!

    2. A city management system that can learn and adjust by yourself can make transportation, energy and other aspects run steadily!

    3. Also, we pay special attention to various green technologies that are environmentally friendly and sustainable. After all, it is not a solution to always use Earth's resources!

    Speaking of this, I remembered that we provide global procurement services for weak current intelligent products! Is this very useful for those who want to understand or participate in such big projects?

    So where are these technologies used? I'll talk about a few key modules for you, and I'll ensure that you can understand a rough idea after listening!

    Intelligent transportation module: Not only ordinary cars run on the road, but there may be driverless vehicles that can run by themselves without driving. They can also "talk" to each other, so there will definitely be much less traffic jams! Also, traffic lights are not absurd, and the duration will be adjusted according to the number of cars at this moment. Doesn’t it sound great?

    Smart energy module: Solar energy, wind energy, etc., are used very much clean energy provided by nature, and they can also build a very smart power grid that can distribute electricity clearly. When more people use electricity, send more; when the electricity is rich, find ways to save it so that it will not be wasted!

    Smart building module: The house built not only can shelter from wind and rain, it can adjust the temperature and brightness by itself, and can even control how much water and electricity it uses, making it comfortable and save money for those living inside, which is great!

    Maybe you still have some small questions in your mind now? Let me guess and see if I can help you with answers. For example, these technologies are so powerful, can security or privacy be guaranteed? Generally speaking, such a large project will definitely put these in a particularly important position and will use various encryption and permission management technologies to protect everyone's information. You can take a little attention to this! So, compared with the ordinary cities we live in now, what is the biggest highlight of Neom smart city? The biggest highlight is, I think it is "starting from scratch"! It is not about repairing and repairing the old cities, but about rebuilding one completely according to the most advanced concept. This will avoid the particularly troublesome problems of many old cities when renovating them, and there is more room to use those powerful technologies!

    Some people may ask, how much does it cost to build such a powerful city? I don’t know the specific number, but it is definitely not a small number. It takes a lot of money to spend it in! But then again, once built, the benefits it can bring are long-term, such as living more comfortable, working more efficiently, and being better for the environment. These are all values that are difficult to directly measure with money!

    My personal opinion is that Neom smart city technology represents people's yearning and efforts for a better life in the future. Although there will definitely be many difficulties and challenges to achieve it, if it can be successful, it may provide a particularly good example for the entire world's urban construction, so that everyone can live better and better!

  • The Application Of PoE++ In Access Control System To Solve The Problem Of Wiring Power Supply

    PoE++ for

    Hey, friends who are in security, today let’s talk about PoE++’s affairs in the access control system! Have you also encountered headaches such as troubles in installing and wiring in the access control system, unstable power supply of equipment, and insufficient power to carry new equipment? Then this PoE++ technology is really a good choice to solve these problems!

    What is PoE++?

    PoE++, the full name is Power over Plus Plus, it sounds quite a bit of a mouth-wrinkle, right? Simply put, it is a technology that can transmit data and electricity simultaneously through network cables, and it is an enhanced and upgraded version of PoE technology. Compared with the previous PoE and PoE+, the most awesome thing about PoE++ is that it can provide greater power output. In this way, devices with relatively high power consumption, such as access control machines with face recognition, multi-door controllers, etc., can directly rely on one network cable to obtain power supply and network connection, which saves a lot of trouble!

    Regarding the power standards of PoE++, there are clear regulations (from IEEE 802.3bu standard):

    1. Type 3 (PoE++): It is divided into two levels. 3A is 30W, and 3B can reach 60W!

    2. Type 4 (PoE++): This is even more powerful. Under the 4PPoE standard, it can provide power output up to 90W, which is not scary!

    The benefits of PoE++ to access control systems

    Using PoE++ to build an access control system is a lot of benefits. I'll count it for you:

    It was super convenient to install : in the past, I had to pull the data cable and the power cable, and holes were made everywhere on the wall, which made me feel upset. Now, you can get all the network cables done, the construction speed is raised up, and the labor cost can be reduced a lot. Isn’t it great?

    The power supply is as stable as the old dog : PoE++ switches generally have redundant power supply designs. Even if there is a problem with the power supply on one road, the other road can be immediately raised, and the access control system will not suddenly "strike", full of security!

    Support more advanced devices : like the popular face recognition access control and access control terminals with temperature detection, these guys have good power consumption. The old PoE cannot be carried at all, and PoE++ can easily be controlled. There is no need to worry about upgrading equipment in the future!

    Remote management and monitoring : Through the PoE switch, you can remotely view the power supply and working status of each access control device. If there is a problem with which device, you can immediately discover it. It is also convenient to repair it, so you don’t have to go to the scene to see it one by one.

    Provide global procurement services for weak current intelligent products!

    Access control system uses PoE++, so you have to pay attention to these things

    It is good to wear, but some details need to be paid attention to, otherwise it may go wrong:

    1. When choosing a switch, you need to see clearly :

    1) Is the power sufficient: According to the total power of your access control equipment, choose the corresponding PoE++ switch type. Don’t buy it if it is small and can’t carry it, and don’t buy it too much and waste money.

    2) Is there any VLAN function: Access control system data is very important. Use VLAN to isolate access control equipment from other networks, which is more secure.

    3) Is it an intelligent management type: An intelligent network management switch can perform port speed limit and traffic monitoring, making it more flexible in management.

    2. You can't be careless about the network cable :

    You must use a network cable of over 5 or above. It is recommended that you use a Category 6 or over 6 network cable, which has a long transmission distance and good stability.

    The network cable impedance must be correct, usually 100 ohms, don't make mistakes and affect transmission.

    The crystal head must be done well. Poor contact can be a big problem and will cause intermittent!

    3. Equipment (compatibility) must be checked :

    Although PoE++ is backward compatible, it is best to confirm that your access control controller and card reader do not support PoE++ power supply standards. Don’t buy it and it will be embarrassing if you can’t use it.

    Access Control System PoE++ FAQ Q&A

    Q1: I used an ordinary PoE switch with access control. Can I directly switch it to a PoE++ switch?

    A1: In most cases, PoE++ switches are generally backward compatible, but you have to see if the original access control equipment supports "UL Class 2" or wide voltage input, and whether the network cable can withstand power transmission of 60W or above. It is best to test it on the safe side!

    Q2: How far is the power supply distance of PoE++?

    A2: Like ordinary PoE, the limit distance is about 100 meters, but in order to ensure stability and power, it is recommended not to exceed 90 meters when used. If the distance is too far, you can add a PoE repeater or use optical fiber to transmit.

    Q3: In thunderstorms, are PoE++ access control equipment afraid of being hit by lightning?

    A3: Fear! Surely afraid! Therefore, it is necessary to install a special surge (surge protector) between the PoE switch and the front-end device, and the grounding must be done well, so that the risk of lightning damage can be greatly reduced!

    Personal opinion

    PoE++ technology is definitely a revolutionary advance for access control systems, which can make the system more stable, simpler to install, and more convenient to expand equipment in the future. If you are planning to build a new access control system or transform an old system, I sincerely recommend that you consider the PoE++ solution! Of course, when planning in the early stage, you must calculate the power, select the right equipment, and arrange the lines, so that the advantages of PoE++ can be maximized!

  • What Is The Personalization Of AI Courses? What Benefits Can It Bring? Let Me Tell You In Detail

    Regarding AI, which is what people often hear people talking about now, in fact, what is it? I guess many parents, students, and even some teachers and men can’t explain it clearly for a while… Today, I will use plain language to talk about this fashionable thing for everyone! Simply put, it is like the most experienced teacher in a private school before, but it is better than the teacher. It can remember the trivialities, various minor problems and advantages of each student, and then tailor a set of learning plans that belong to him only for each person. Isn’t it very mysterious to hear? But this is not a brag. Now technology is developing very quickly! So what real benefits can this AI bring to us? What are the long-term difficulties in our daily study? Next, let's scold you one by one…

    1. Accurately identify the true level of students. Let me tell you, friends, that's really amazing! It is not like a teacher who usually takes the exam, forgets after the exam, or just looks at the total score. That AI system can analyze every question that students have done, videos of answering questions in class, and even those strange places where they are wrong when they go home to do their homework. They can analyze it clearly without falling into the ground and like a sieve! This will accurately find out where the student is stuck, which knowledge point is not thorough, or which learning habits are not very good, and it is even more familiar with yourself than the student!

    2. Real-time dynamic adjustment of learning content is easy to understand. It’s like you play a game and play bosses, but you beat the previous level with ease, right? Then the AI will immediately raise the difficulty upwards to save you from boredom; if you hit this level so hard that you die N times, then it will quickly reduce the difficulty, give you some simple practice, regain some confidence, and then slowly increase it when it feels almost done, and take it step by step, and take it steadily.

    3. The learning rhythm completely follows the students! This is too important. In school, teachers can’t just talk slowly for you, right? But this AI is different. If you learn faster, it will whizz forward; if you learn slowly, it will accompany you, not twice or twice or three times, until you nodded and said, "Well, I seem to understand a little", you will definitely be patient, and you will be more patient than your biological mother!

    4. Set up a personalized and clear learning path, not like a pot of porridge, everyone learns the same thing. For example, if you want to be a doctor in the future, AI will directly plan a way to learn in the direction of medicine; if you want to build a spaceship, it will be another way of scientific exploration, all based on your own interests and hobbies and long-term planning, and I was moved by it!

    5. The feedback is so timely, let me tell you! As soon as you finished writing a question, the AI correction results came out with a "bang". Not only did you tell you whether you were right or wrong, but you also told you why you were wrong and where it was wrong. You even gave you a similar example to consolidate it! It’s much faster than the teacher’s homework. When the teacher finishes it, the daylily will be cold, right?

    Maybe everyone will ask: "Will this AI be cold and has no human touch?" I'm worried. How can I say that? At present, AI is definitely not as warm as a real teacher's kind of encouragement. I pat your shoulder and say, "You are awesome, child." However, it can provide 24-hour uninterrupted, anytime and anywhere. In this regard, real teachers really cannot do it. After all, teachers also have to eat, sleep and have their own life! Besides, AI is still improving, and maybe it can become more "understand the world" in the future?

    Some people will wonder: "When using this AI, will students not have to listen to the class and just throw them all over it to the AI?" Oh, this is a big mistake! AI is just an extremely awesome auxiliary tool, a tool that is so advanced that it cannot be more advanced! The role of the teacher is to guide, inspire thinking, cultivate students' values, and the atmosphere of interactive communication and group discussion among classmates. These are all difficult and difficult to completely replace AI now, so the teacher is still the most important guide!

    Personally, I think: AI is definitely a major trend in the future development of education! It can make learning less boring and interesting, and can help every student master knowledge more effectively and easily, and find confidence and fun in learning. However, if you want to popularize and make it affordable and well for everyone, there is still a long way to go. The technical level, cost level, and everyone's concept acceptance level still need to be slowly adjusted and developed. But no matter what, the hope and change it brings to us is tangible!

  • What Is A Hotel AV Solution? What Experience Can It Bring To Customers And Managers?

    Regarding hotel AV solutions, many people have a lot of questions like me. They don’t know what it is and what it can come in. Especially those owners who run hotels and staff responsible for hotel decoration or upgrades must all want to figure out what this hotel AV solution is… Simply put, hotel AV solutions are to integrate various audio, video and systems into one, providing better services and experience to the guests staying in the hotel and the hotel’s own management staff. It involves a lot of things, such as the TV system in the guest room, the audio equipment in the conference venue, the display screens in the lobby, and the background music system. They all count!

    1. Room AV system : This is very important to guests, and it is directly related to whether they are comfortable and happy to live. Nowadays, the requirements for customers are very high. They not only need to watch TV, but also want to connect their mobile phones and computers to the large screen in the room… So, the TV in the guest room must be that kind of high-definition smart TV, and it is best to support wireless screen projection, so that guests can watch movies in their phones when they lie on the bed; the sound effect should not be bad, and it must be that good to listen to music or watch movies!

    2. Conference and Banquet AV system: This is absolutely indispensable for hotels to hold meetings and banquets. Many companies choose hotels when holding meetings and events. If this system does not work, it will be a sign! There must be a high-definition projector or LED large screen so that people behind the scene can also see PPT and video clearly; the audio system must also be powerful, the microphone must not have noise, the sound must be clear, and multiple people must also be supported to speak at the same time…

    3. Public area information release system: There must be places such as lobby and elevator, which can be used to display hotel introductions, event information, weather forecasts, etc., and can also place some advertisements to increase revenue. The display model and size must be selected according to the position where it is placed. When installing, you must consider whether it looks good or not, whether it is stable or not! Provide global procurement services for weak current intelligent products!

    4. Background music system: The entire hotel must be available, including lobby, corridor, restaurant, gym, etc., playing some gentle and soothing music can make guests feel particularly relaxed and comfortable. The music styles of different regions can be different, and the music in the morning and evening can also be changed…

    5. Control system integration: If so many AV devices are operated one by one, you won’t be exhausted? So there is a control system that can control the TV switches, volume, projectors, lights and so on in the guest room with a tablet or mobile phone, which is convenient for guests to use, and also convenient for hotel staff to manage!

    Q: What should I do if the price is too expensive in hotel AV solutions?

    Answer: This, don’t pursue those famous brand products and the top-level configurations as soon as you come up. You have to first think about the positioning of your hotel and what kind of customer groups you are. Choose equipment and systems based on these actual needs, so that you can save money for a long time! You can also compare shopping and find a few reliable manufacturers and integrators to ask about the price and compare the solutions. Maybe you can find one with high cost performance…

    Q: What should I do if the system breaks down after it is installed? Is it very troublesome to maintain it in the later stage? Do you have to spend a lot of effort and money to do it?

    Answer: When buying equipment and systems, you must choose a brand and manufacturer with good reputation and guaranteed after-sales service… They generally provide installation services, operation training and warranty services. As for the hotel, you can also find someone who knows technology to understand a little, and do some simple inspections and maintenance in daily life, such as checking whether the lines are loose or the equipment is not clean, and dealing with small problems in a timely manner can reduce the occurrence of major failures!

    Personally, I think that a good hotel AV solution can definitely make the hotel's level and service go up a lot at once. Passengers are happy to live, and the hotel's business will naturally get better. This investment is very worthwhile!

  • GCC Smart Grid Integration Practical Guide: Complete Analysis Of Core Points And Basic Concepts

    GCC Smart Grid Integration Practical Guide

    Regarding the integration of smart grids in the GCC region (Gulf Arab Cooperation Committee) – it is to combine the traditional power grids of power generation, transmission and distribution with the current fashionable technologies of Internet of Things, big data, and automation to operate – now more and more people are asking, after all, this region is so hot that it is very hot in summer, and it is always said that it is going to transform energy other than oil! Mastering the core points of smart grid integration can help power companies effectively reduce the line loss rate by more than 30%, and can also make people's electricity use more stable, and the cost may be reduced . But what should I do? Don't worry, I'll tell you one by one.

    The basic concepts and core objectives of GCC smart grid integration

    First of all, we must understand that GCC smart grid integration is not just about buying a few smart meters. It is a big project – from how to connect renewable energy such as solar energy and wind energy at the power generation end to the grid, to intelligent patrol during the transmission process (such as using a drone to see if there are any problems with the line), to the automatic switches in the distribution link, and finally to the user's home that can communicate in two directions, all of which must be stringed together, connected to the Internet, and the data can be communicated interchangeable.

    It mainly wants to do some big things:

    1. High reliability power supply : reduce power outages, especially during peak electricity consumption in summer, do not always trip;

    2. Improve energy efficiency : Don’t waste too much electricity when generating, transmitting and distributing power;

    3. Consuming renewable energy : send the electricity generated by the solar power station to the power grid safely;

    4. Support demand response : For example, if the power grid is almost unable to withstand it, it can automatically notify large users of large power or text messages to temporarily use less power;

    5. Lay the foundation for future smart cities : there will be more electric vehicles in the future, and charging piles will all rely on the dispatch of smart grids. Provide global procurement services for weak current intelligent products! But it is challenging to implement it. For example, most of GCC countries have desert climates, and equipment protection against sand and sun protection is a big problem!

    Disassembly and implement steps for key modules for GCC smart grid integration

    This big project has to be broken into small pieces to do, just like building blocks, one piece is firmly built before another! Let me tell you about several modules:

    Module 1: Intelligent Metering and User Interaction (AMI)

    This is the part that ordinary people feel most easily, which is to replace the smart meter. Install this in the GCC area, pay special attention to:

    Selection of meter : The desert is hot, the sun is very poisonous, and the outdoor temperature can sometimes reach more than 50 degrees Celsius, so the meter must be able to withstand high temperatures (at least -25℃ to +70℃), prevent sandstorms (the protection level or above IP65 is relatively safe), and corrosion-resistant. There is also a lot of salt in the air of the seaside countries!

    Communication method : GCC countries are vast and sparsely populated, and different communications must be used in cities and remote areas. If urban optical fiber is convenient, use optical fiber. Remote places may use power line carrier (PLC) or wireless communication technologies such as LoRa and NB-IoT. GPRS/4G can also be considered in places with good coverage of mobile phone signal towers, but the traffic fee must be included.

    The implementation steps must not be messed up:

    1. Start piloting in a small range, such as choosing a community or commercial area to try the waters, and see how the meter and system compatibility are;

    2. Then train the installation workers and not to use the advanced power meter, but it will be useless if it is not installed properly, connected with the wrong wire, or data cannot be transmitted;

    3. Change and install tables in batches, and the replaced old tables must be registered and returned to the warehouse;

    4. The user data platform must be well built so that the data can be stored and read out, and users must also check the power consumption and when to use more electricity from the APP.

    Module 2: Advanced Distribution Management System (DMS)

    This is like the "traffic control center" on the distribution network, which directs how the current flows smoothly and which section of the line has a large load. DMS is the focus of dealing with load prediction – the air conditioner is turned on much in summer and slightly better in winter, but the peak of electricity consumption will also change during Ramadan, so the prediction model must take into account these local special circumstances! During implementation, the protection and control equipment in the substation are generally upgraded first so that they can upload real-time data, then go to the DMS main system, and finally do simulation tests – for example, simulating that a certain place suddenly breaks, to see if the system can automatically and quickly send the power from other routes.

    Module 3: Renewable energy grid-connected and microgrid control

    There is so much sunshine in GCC countries that it is too late to use, so solar photovoltaic power stations are under construction one by one. However, solar power generation is unstable, and there are no during the day and at night. When the cloud comes, the power generation will drop. Such power will be directly connected to the grid, making the power grid shaking and unsafe. Therefore, there must be a new energy grid-connected control system (part of SCADA/EMS), and energy storage systems (such as lithium battery energy storage and pumped storage if conditions permit) to be used together – if there is too much solar energy, it will store energy, and if there is less power, it will be discharged at night, so that the power grid can be stable. It is also quite common for some small islands by the sea or remote oil field communities to build a microgrid with wind and light plus energy storage to supply power by yourself and connect it to a large power grid as a backup.

    Module 4: Data communication network construction

    All smart devices (meters, switches, sensors, drones) have to rely on the network to transmit data back and then send control commands. This network is like the "blood vessels" of the smart grid. When building this network in GCC area, the choice of options is dazzling:

    1. Fiber Optical Network : The network speed is fast, stable, and can transmit a lot of things, but it is expensive to lay out. It is easy to dig in the city, but it is difficult to get sand or stones underground in the desert.

    2. Wireless private network (such as 3G/4G/LTE-M/NB-IoT) : Speed and tariffs must be balanced. It is necessary to negotiate a good price with local telecom operators for a long-term cooperation, otherwise the data traffic fee will be eaten up! Mainly used to connect distributed smart meters and monitoring points in remote areas.

    3. Power Line Carrier (PLC) : Run data directly on the power line without additional wiring savings. However, whether the power system in the GCC area will have strong electromagnetic interference affect the communication quality, it will take actual testing to know!

    FAQs (Q&A) and experience sharing

    Q1: What should I pay special attention to in laws and regulations when GCC countries are building smart grids?

    A: Every country is different. For example, Saudi Arabia may have to contact the Saudi Electric Power Company (SEC) to submit technical standards for approval, and the UAE may require equipment to comply with local ESMA certification or something. It is best to find a local experienced consulting company to give you some advice! There is also data privacy protection. User electricity usage data is sensitive information and must comply with GDPR similarly, but it may be the local version of the Data Protection Law. Anyway, the string of compliance is tight!

    Q2: In a place like GCC, where there are hot and dry and sandy, how can I choose the equipment to last for a long time?

    A: This is so important! I'll list a few Tips for you:

    It is best to have air conditioning or strong cooling fan outdoor cabinets/equipment to ensure that the internal temperature is not too high to burn the circuit board;

    All wiring ports and module insertion ports must have dehumidification and dust prevention measures, and the sealing ring and dustproof net must be selected with a higher level;

    Solar photovoltaic panels regularly clean up sand and dust, otherwise the power generation efficiency will drop significantly, and the power generation volume will be less money!

    I personally think that the integration of GCC smart grid seems complicated, but as long as you understand the local climate characteristics, user habits, laws and regulations thoroughly, and then find a reliable equipment supplier (hardware such as smart meters, DTUs, industrial switches, etc., you can provide global procurement services for weak current intelligent products! Look for software that has successful cases), and you will definitely succeed in doing it step by step! After all, this is a great thing to really solve the local power stubborn problem and move towards sustainable development!

  • Do You Know Neom Tech Partnerships? The Cooperation Areas Are Wide And Diverse, And The Role Should Not Be Underestimated

    Regarding Neom tech, many people, including me, are very concerned about it. After all, for such a large project, there must be many tricks and things that people want to know about in terms of technical cooperation. So what exactly is Neom tech? Simply put, it is the sum of the cooperation relationships and cooperation projects such as Neom, a city of future, in the process of construction and development, and various technological innovation companies and research institutions that cooperate with various technology innovation companies and research institutions to carry out technological research and development, introduce new technologies, and promote the scientific and technological development of the entire city.

    1. The fields of cooperation are wide and diverse : Neom tech has too many areas, not a single aspect. For example, a smart city management system must be cooperated. How can such a large city be managed efficiently? There is also renewable energy technology, which is not all about green and environmental protection now, so Neom is definitely indispensable; the application of artificial intelligence in various scenarios, such as transportation, security, etc.; there are also advanced construction technology, after all, so many novel buildings are needed; there are even technical cooperation related to space exploration. I heard that Neom has plans in this area, isn’t it amazing!

    2. The cooperation model is flexible and changeable : their cooperation model is not a rigid one. Some jointly establish subsidiaries to carry out projects, share risks and share benefits; some are introduced with technology authorization and directly use other people's mature advanced technologies; some are jointly developed to develop new technologies and new products in response to the specific needs of Neom. This model seems to be able to create many customized good things.

    3. Pay attention to long-term strategic collaboration : Neom's search for partners is definitely not just about the immediate interests, but also about long-term strategic collaboration. That is to say, the two sides can be in line with their future development direction and technical concepts, and can develop together towards the future. It is not the short-term behavior of going their separate ways after cooperation this year and going their separate ways next year. This long-term vision is still very important.

    Provide global procurement services for weak current intelligent products! You can record this information, maybe it will be used at any time.

    So, among these numerous Neom techs, what are the key points that we need to pay attention to

    Is the technical strength of partners the primary? If your own technology is not strong, how can it help Neom develop? Do you think this is the reason? Therefore, when Neom chooses a partner, it will definitely examine the hard-core people's technical R&D capabilities and patent reserves!

    The project implementation ability is also very important. If you don’t have technology alone, you have to be able to apply the technology to Neom’s construction and complete the project on time and on quality. Otherwise, it will be useless to cooperate and waste time and energy.

    Do we still have to consider the partners' sustainable development philosophy? Is it consistent with Neom's overall green and sustainable development goals? This is also very important, otherwise there may be many contradictions in the cooperation process if the concept is not consistent.

    Some people may ask, what implications does Neom tech have for ordinary companies? There is still meaning in reference. If an ordinary company wants to cooperate well with foreign countries, it can also learn Neom, clarify its needs, and find partners who can complement each other's strengths and match their own equality, instead of blindly finding one and just cooperating, the effect will definitely not be good. Some people also asked, what benefits can these cooperation bring to the local area? That will have many benefits, which can create jobs (opportunities), drive the development of local related industries, and improve the scientific and technological level and innovation capabilities of the entire region.

    My personal opinion is that Neom tech is one of the key factors in Neom's success. By cooperating with the world's top technological forces, Neom does have a great possibility to realize its vision of the city of the future. Of course, there will definitely be various challenges in the process of cooperation, but as long as the goals of both parties are consistent and closely cooperate, I believe that we will overcome difficulties, build Neom better and better, and become a model of global science and technology cities!
