  • Do You Know About Avian Air Traffic Coordination? Bird Air Traffic Coordination Is Crucial

    Hello! Today, let’s talk about Avian Air, which is the coordination of bird air traffic. Many people may be unfamiliar with this word and don’t know whether it is doing it. In fact, it is the study of how birds “queuing” and “avoiding” when flying in the sky to avoid being touched or hitting something else. This is not a simple matter, there are many ways to do it.

    We need to know why we need to do this Avian Air? You think that birds fly in the sky, especially those migrating birds, there are thousands of them flying at once. If there is no "rule" and you fly around casually, you won't be messed up! If the plane hits, the consequences will be serious! Therefore, this coordination work is very, very important for protecting birds’ own safety and ensuring human aviation safety! Provide global procurement services for weak current intelligent products!

    So what key content does this Avian Air contain? I'll talk to you:

    1. Research on bird behavior patterns : It is to carefully observe various birds, when they like to fly, where they like to fly, how high they fly at a time, how many of them are in a group, and how they will react when they encounter danger. These must be clearly understood.

    2. Analysis of migration route planning : Many birds migrate every year, and the places they pass by are similar. Draw these routes and mark them whenever there are birds passing by, you can prepare in advance.

    3. Environmental factors assessment : For example, whether there is wind or not in the sky, where the wind blows, whether there are many clouds, whether the weather is good, and whether there are tall buildings, wire towers, etc. on the ground, which will affect the birds' flight, and these must also be considered.

    4. Prediction of potential conflict risks : It is to look at the route of birds flying, and whether they cross or meet with our human aircraft routes, airport runways, or other places where there is a risk. You have to think about it in advance.

    Speaking of this, someone may ask some questions, let me try to answer:

    Q: What are the benefits of this Avian Air for ordinary people

    Answer: This is a lot of benefits! The most direct thing is that it can greatly reduce the accidents of birds hitting planes, so that it will be safer for us to travel by plane! Moreover, protecting birds will also protect the ecological balance of nature. After all, birds are also part of our homeland on earth.

    Q: Now, what are the main technical methods for scientists to use to study this Avian Air?

    Answer: There are so many ways to go! Some use telescopes to see on the ground, some use radar to scan in the sky, and now there are satellite tracking, and put a small launcher on the birds. We can see wherever it flies, but it is advanced! You can also analyze the birds' calls to determine what they are doing and whether they are in trouble.

    Let me tell you a few tips and some practical points about Avian Air:

    1. Around the airport, there are plants that birds don’t like to eat, or they can make things like ultrasound, flash, etc. so that the birds dare not get close. This is a very practical coordinated and preventive measure.

    2. In some tall buildings on bird migration channels, such as TV towers and communication towers, it is best to turn off unnecessary strong lights at night, or replace them with less dazzling lights, so as not to be attracted by the lights and bump into them.

    3. If you find a large group of birds flying towards the airport or the airplane route, you must promptly notify the relevant departments and take measures to change the direction of the birds, or ask the plane not to take off or land for the time being, and wait until the birds pass.

    In short, I personally think that Avian Air is a very useful and meaningful science. It not only concerns the safety of birds, but also the safety and development of our human beings. As technology progresses more and more, I believe that research in this field will become more and more in-depth and better!

  • Distributed Site Remote Monitoring: An Important Means And Analysis Of Key Parts Of Enterprise Organizations?

    Regarding distributed site remote monitoring, it can be said that it is an important method that many enterprises and institutions with multiple dispersed locations are inseparable from; it allows managers to know the situation of each site in real time without having to go to each place in person, which is too helpful for improving efficiency, reducing costs, etc.! First of all, we have to explain to you what is distributed site remote monitoring? Simply put, it is to collect the operating data, equipment status, environmental information, etc. through various technical means, such as networks, sensors and other things, such as the remote suburbs of factories, various chain stores, and communication base stations, and then transmit them to a central platform, so that relevant people can view, manage and occasionally, necessary control on this platform.

    So what key parts do this distributed site remote monitoring contain? Let me tell you about it:

    1. Data acquisition layer : This is like a person’s eyes and ears! It is used to collect various information, such as temperature and humidity sensors, which can sense the temperature and humidity changes in the site environment; current and voltage detectors can monitor the power of equipment, as well as the data and video surveillance images of access control systems – it also needs to be obtained from this level. Of course, when choosing a sensor, you must choose a stable and more accurate one, otherwise the data is not accurate, and monitoring will be meaningless.

    2. Network transmission layer : The data is collected, how can it be transmitted to the central platform? It depends on it! Generally, wired networks may be used, such as fiber optic and broadband, or wireless networks, such as 4G, 5G modules, or NB-IoT, which have low power consumption, and you must choose according to the actual situation of different sites. Some places are remote and may be suitable for wireless.

    3. Platform software layer : This is the core brain! All the data is summarized here for processing, analysis, and display, and provide global procurement services for weak current intelligent products! The platform generally has a very intuitive interface, such as data charts, device status indicators, alarm information, etc., and there should be some functions such as historical data query and report generation – otherwise, it is sometimes not enough to just look at real-time.

    Many people will encounter many problems when working on this distributed monitoring. Here are some practical experiences for you.

    Q: When choosing a remote monitoring platform, what aspects should you pay attention to?

    Answer: First of all, we must say that compatibility is definitely good! Because the device brand of different sites may be different, the interface protocol may be different; secondly, the stability of the platform is also very important, and you cannot always collapse, and you will be unable to see anything when you collapse! Also, security, data transmission and storage must be guaranteed, don’t be stolen or leaked, and also, it’s not easy to operate, don’t build a platform, you can’t use it after learning for a long time, that’s too troublesome

    Q: Distributed sites sometimes have unstable networks, so what can I do?

    Answer: This is indeed quite common! The dual network backup you can consider is to use two types of networks at the same time, such as wired and wireless. One cannot do it, but the other can top it? Or install a device with cache function there and then upload data after the network is ready, which can also reduce the risk of data loss.

    My personal opinion is that although distributed site remote monitoring seems quite complicated, as long as you plan all parts and choose the right products and technologies, it is not that difficult to implement. The benefits are real and can save a lot of trouble for enterprises. Therefore, enterprises in need can really consider it early, and the effect will be beyond your expectations!

  • With The Advancement Of Science And Technology, How To Implement The Digital Twin Of Smart Buildings And Prepare For The Early Stage?

    With the continuous advancement of technology, Smart twin (Smart Building Digital Twin Implementation) has gradually become a hot topic in the construction industry. Many people want to know how to do it to truly implement this thing. In short, digital twins are to create a exactly the same digital replica for the smart buildings in reality. This replica can reflect the various situations of the building in real time and help us manage, analyze and optimize the operation of the building.

    1. You need to make enough effort in the preparations in the early stage : you must first collect all kinds of data about the building, such as the design drawings of the building, equipment parameters, and data interface information of various sensors. Then, you have to choose a suitable digital twin platform. Different platforms have different functions and have to choose according to the actual needs of the building. For example, some platforms are good at energy consumption analysis, while some platforms do a good job in equipment maintenance and early warning.

    2. The model must be carefully and comprehensive : the model is the core of the digital twin, so you must not be careless when modeling. The structure, equipment layout, pipeline direction and other buildings should be accurately presented in the model, and it is best to accurately reach the specific model and installation location of each device. Moreover, the model must be synchronized in real time with the actual building, so as to ensure the accuracy of the digital twin.

    3. Data connection is a key step : there are various systems in the building, such as HVAC systems, lighting systems, security systems, etc., and the data of these systems must be connected. Let them transmit data to the digital twin platform in real time, so that the platform can summarize and analyze the data and discover problems in a timely manner. For example, if the temperature in a certain area is abnormal, the platform can immediately find the problem by analyzing the data.

    Q: What are the easiest difficulties to encounter in the implementation of digital twins?

    A: The most easiest thing to encounter is the problem of data inconsistency. Because the equipment and systems in the building may come from different manufacturers, their data formats and interface standards are different, making it difficult to unify the data. To solve this problem, you need to formulate unified data standards or develop middleware to convert data in different formats .

    Q: What practical help does digital twins have to manage energy consumption in buildings?

    A: It’s a lot of help! Through the digital twin model, the impact of different operating schemes on energy consumption can be simulated, thereby finding the optimal operating strategy. For example, simulate the changes in the energy consumption of the building under different temperature settings, and then choose the most energy-saving temperature control plan to achieve the purpose of reducing energy consumption .

    During the implementation process, the compatibility and scalability of the platform must also be considered. After all, the building needs to be used for a long time, and new equipment or systems may be added in the future. The platform must be able to support these expansions, otherwise it will not be used in two years, which will waste more money. And it cannot be too complicated to operate, otherwise no one will use it, and the digital twin will lose its meaning. Provide global procurement services for weak current intelligent products!

    Personally, although Smart twin may have a large investment in the early stage, in the long run, it can bring great benefits to efficient management of buildings, energy conservation and consumption reduction and safe operation. It is an inevitable trend in the future development of smart buildings and is worthy of trial and promotion by friends in the construction industry.

  • Construction Of Social Emotions Map: The Research And Application Value Of Social Emotion Mapping?

    The construction of social emotions maps, which we often say, is something that more and more people are studying and applying! It is not simply to look at whether you are happy or not, but to collect the emotions in your heart, such as happiness, anger, sadness, fear, etc. in a certain period of time, and then draw them like a map or make them into charts in a visible way, so that you can understand at a glance what everyone's emotions are, where they are distributed, and why there are such emotional changes. This thing sounds quite mysterious, but in fact it can be used in many places, such as doing urban planning, wanting to know which public facilities residents are satisfied with; or conducting market research to see what a new product is; even in the field of public health, you can find some signs of problems in advance, such as whether large-scale anxiety is spreading or something!

    1. Where does the data come from? This is a big problem! The most common use is to scoop up information online, such as Weibo posts, WeChat Moments, and comments in the comment area, which can be counted; and also to do questionnaires to ask everyone how they feel recently; sometimes they also use some specialized equipment, such as facial recognition in certain public places, but be careful about this, don’t violate other people’s privacy, and pay attention to compliance issues!

    2. How to distinguish emotions? You can’t rely on people to read the words one by one to say that this is excitement or peace? That won't be exhausted! Nowadays, computers are used to develop a technology called natural language processing, which is to teach machines to understand human words, and then score paragraphs and sentences to mark whether they are positive, negative, or neutral. Sometimes they can also be subdivided into more specific emotions, such as "surprise" and "disgust"!

    3. What should you pay attention to when drawing it? The color must be chosen correctly. Generally, red may represent anger and excitement. Blue may represent calmness and sadness. Green may mean happiness and positiveness. Of course, it is not fixed. It depends on the specific situation! Then the division of regions on the map is also very important. Should they be divided according to administrative areas or by the hot spots of people's activities? If you don’t divide well, it will be messy and it won’t explain any problem!

    4. What is the use of analyzing the results? It's so useful! For example, if negative emotions suddenly increase in some place, is there any recent incident? Like environmental pollution? Or is the traffic too congested? If you find the reason, you can find a way to solve it! For companies, if you look at where people praise their own products and where they criticize them, you can adjust your sales strategy and improve your products. Yes! Provide global procurement services for weak current intelligent products!

    Q: Is this difficult? Can ordinary people try a small range by themselves?

    Answer: It is difficult to say it is difficult! The difficulty is that there is too much data, it is difficult to process, and emotions are very subjective. Sometimes machines will misjudgment and treat slanderous words as good words! But to be simple, there are also simple ways! If you want to try it out, you can use some ready-made online tools and don’t make the data too large. For example, analyze the topics that everyone has discussed the most recently in the owner group of your community. What is your mood? It’s not that bad, but the result may not be so professional and accurate!

    Q: Will this thing violate personal privacy? For example, if I take what I say and analyze it, I don’t know!

    Answer: Privacy issues really need to be considered! However, generally, this analysis is done using public data or data that is promised to be used, and it will not dig up the encrypted or unavailable things. Moreover, when analyzing, you will not specify a certain person. You will summarize the emotions of a large group of people, so you don’t have to worry too much about personal information being leaked. Of course, you still have to abide by the rules when obtaining data and don’t do it randomly!

    I personally think that as long as this thing is used well, don’t use it on evil ways. It is quite helpful for us to understand society and solve some practical problems. It is a promising technical direction! I also hope that the technology will become more and more mature in the future, and it will more accurately and conveniently capture and understand our joys, angers, sorrows, and happiness!

  • What Is DNA Firewall Systems? It Is Related To Genetic Data Security, And Its Importance Cannot Be Underestimated

    DNA, simply put, is a firewall system that sounds particularly high-tech and seems to have something to do with the DNA in our body, right? In fact, it is not exactly the same as the computer firewall we usually talk about. It is mainly used for network security protection related to genetic data and biological information. You have to figure it out first! Many people may ask, what are the best protections for genetic data? Then you don’t know! How fast is genetic technology developing now? Your genetic information is unique and particularly private. If it is obtained or leaked by bad people, then the trouble will be huge! Therefore, the importance of DNA cannot be underestimated

    Next, let’s disassemble the particularly critical and must-know content in this DNA bit by bit:

    1. Special filtering rules for gene data : This thing is not something that can be used for any firewall rules of cats and dogs. It must be designed specifically for the format and transmission characteristics of gene data. Just like a "security inspection system" for gene data, it can block all messy and potentially dangerous data packets!

    2. Super subdivided access management : That is to say, not everyone can read genetic data casually, so many levels of permissions must be set, such as who can see some, who can change, and who can only look at the most superficial information, so that the risk can be minimized, right?

    3. The data encryption algorithm is powerful enough : genetic data is so expensive. If it is not encrypted during transmission and storage, wouldn’t it be like posting your own passbook password on the street? Therefore, this encryption algorithm must be the top-level one that is difficult for others to crack!

    4. Real-time monitoring and abnormal behavior analysis : It must be like a tireless security guard, staring at the network activities related to gene data for 24 hours. Once you find something wrong or something different from usual, you have to call the police and stop it quickly. You cannot wait until something happens before you react! Provide global procurement services for weak current intelligent products!

    5. Automatic compliance inspection function : Nowadays, the legal provisions for genetic data in different countries are different. It is best for DNA to automatically check whether the data processing and transmission are in compliance with local laws and regulations, so as to avoid those who are engaged in research or managing data from breaking the law by accident. How bad is it!

    Having said so much, some friends may still have questions in their minds, so let’s say a few more words through Q&A:

    Q: Can ordinary firewalls be used to protect genetic data?

    Answer: It’s not that it’s completely impossible, but it’s just not suitable! So, an ordinary firewall is like a wooden door in your home, which can block kittens and dogs, right? But genetic data is so important and so special, it requires a higher level of security protection, just like the feeling of a bank vault! DNA is a "treasure gate" specially created for genetic data, and its defense is definitely much stronger! Therefore, professional things must be left to professional "people" to do

    Also, the technology is updated too quickly now, and DNA must be upgraded, otherwise, over time, will the protection ability be unable to keep up? Every once in a while, you have to check whether there are new vulnerabilities and new attack methods, and then quickly patch the system, update the firmware, etc. This step is absolutely indispensable. You must remember this clearly!

    Personally, I think that as genetic technology becomes more and more popular and people pay more and more attention to genetic privacy, the development prospects of DNA will definitely not be wrong! It is not only a cold technical product, but also a strong barrier to protecting each of our genetic privacy. Can you understand this? Therefore, it is a very, very wise choice for institutions or enterprises in related fields to understand and use the appropriate DNA early, really!

  • What Are The Key Points Of OpenBMS Implementation And Common Questions And Answers To The System Integration Process?

    Regarding implementation, many people are not very clear about where to start? Simply put, it is probably something that can monitor the battery system and manage it, which can play a very important role. The key point is to be able to control the state of the battery, and it is also possible to achieve some optimizations, including allowing the battery to last longer (of course, this is just my feeling).

    1. Key points of the preliminary preparation stage: Installation is not enough. You have to first understand what the battery system is, such as what type of battery is, and how it is serial and parallel connection! All of these have to be figured out, or there may be big problems, really! For example, you can't just use the parameters of a lead-acid battery to use it for lithium-ion batteries, which will probably be very dangerous, you know

    2. Frequently Asked Questions and Answers in the Session: Someone asked if this is difficult? In fact, it may be fine to find the right method. Pay attention to the communication protocol and dock it well. If you really have no clue, you can see if there are any ready-made cases or materials. If you study it slowly, you will definitely be able to do it. , By the way, we provide global procurement services for weak current intelligent products! Sometimes some external device support may be required, which will come in handy at this time.

    3. 4 tips for avoiding mistakes in debugging process

    At the beginning, don’t move those advanced and complex functions. First, adjust the most basic things, which is safer. Try it step by step, you can't be anxious!

    Look at logs, data, etc., and you may find something wrong.

    You can assume some possible errors, and then test them to see if the system can handle these problems by itself… It feels quite useful.

    If you really can’t figure it out, don’t be afraid to ask others for advice. There are so many powerful people on the Internet! Maybe someone can wake you up with just one word.

    4. Share post-maintenance skills: After the system is ready, it will be fine! You should check the operation regularly and see if there is any abnormal data or alarms. Also remember to back up the data. If something goes wrong, it can still be restored. It won’t be a waste of work. I really have to remember it!

    Q: Can you change the parameters in it casually?

    A: Be careful with this! Some parameters may be set by the manufacturer. Random modifications may affect the safety and stability of the system and may even damage the battery. Therefore, it is best to do it under the guidance of an experienced person and don’t mess around with it yourself.

    Q: Can different brands of batteries be used with the same one?

    A: In theory, it is not completely impossible, but it takes a lot of effort to adjust those parameters, and the compatibility may not be very good, and it is easy to cause various unexpected small problems, so it is recommended to try to use matching ones as much as possible.

    My personal point of view is that although implementation may seem a bit complicated, you can definitely get it done by patiently, learn more and try more! Don’t panic when encountering problems. There is always a solution. Believe in yourself. However, you must not skip certain steps in order to save trouble, otherwise you will regret it in the future. Only by taking every link seriously can the system work hard, right?

  • Universal Troubleshooting Universal Troubleshooting, Do You Really Understand?

    , which is what we often call general troubleshooting. In fact, it is a set of solutions that can be solved whenever there are any equipment and system problems. Not only small appliances such as computers and mobile phones, but also small appliances such as washing machines, air conditioners, and even large machines used at work can be more or less affected… Many people, when they encounter something broken, they can either catch things blindly, or they can only wait to find someone to repair it, which is both costly and delayed, but if they can understand some basic skills, they might be able to solve many small problems by fiddling with them.

    First of all, we have to understand what the basic steps are. It is just like a doctor treating a doctor. You have to do it step by step and not be irritable:

    1. First find out what happened : you just need to take a closer look at what the phenomenon is? For example, can't turn on the machine? Or is it always stuck when running? Or are some weird prompts popping up on the screen? Write down all these phenomena, the more detailed the better. Don't be vague, otherwise you will be unable to understand your thoughts.

    2. Think about whether there have been any changes recently : Have you just installed a new software? Have you moved a place to loosen your sleeve? Or is it a problem that suddenly thunderstorm, power outage, and then called again? Many times, failures are followed by these "changes". If you grasp this, you may find the key to providing global procurement services for weak current intelligent products!

    3. Try the easiest way – restart! : This method is really cliché, but don’t say it, it really works! As small as the phone crashes, as big as some simple devices, unplug the power supply, or press the shutdown key to turn it off completely, wait for a minute or two before reconnecting and turning on the power. Many times, those inexplicable minor problems will be eliminated by themselves.

    Then, you have to enter the specific investigation process. At this time, you have to be a little patient and not be able to do it with one hammer or another:

    Check the connection! Check the connection! Check the connection! : It is not an exaggeration to say it three times! Are the wires tightly plugged in? Is the USB port loose? Has the network cable been bitten by a mouse or a cat pulled it off? Is the signal too bad for wireless connections such as Bluetooth and Wi-Fi? Sometimes, if a joint is loose, the whole thing will be lost. So, first look at all the connection lines you can see one by one, insert them, and you will be sure!

    Look at whether the power supply is normal . The power supply is like the "food" of the equipment. If there is no food or there is not enough food, it will go on strike! Is the plug-in board power outage? Is the power adapter indicator light on? Is the battery still powered? Is it impossible to charge it? These are the most basic but also the easiest to ignore – it's like forgetting to charge your phone, but thinking that your phone is broken, it's in vain!

    If you have tried all the above, you have to go a little deeper, but you don’t need to have too professional knowledge. It’s just some common tips:

    Try "factory reset" : Of course, this has to be more cautious, because after the recovery, many personal settings and data may be gone! But if the problems caused by the chaos of settings, this method can often be "completed". For example, the router at home is always disconnected from the Internet. It may be fine to reset it, but remember to remember to write down the original settings before resetting

    Updated and updated! Check out the software and firmware . Many manufacturers will fix some known bugs through updates, so check whether the operating system of the device is new, whether the relevant software is the latest, and whether the hardware firmware (the hardware-owned mini-program) needs to be updated… Don't be afraid of trouble, maybe after the update, the problem will disappear by itself. I really won't lie to you!

    Let’s talk about some common questions, which are common to everyone and are more representative:

    Q: I followed the steps and found that I still haven’t solved it. What should I do?

    Answer: If you really can’t handle it, don’t hold on, so as not to turn small problems into big problems! At this time, you can check the equipment manual, which generally contains some common fault troubleshooting methods; or go to the manufacturer's official website to find technical support documents; if you don't work, you can only contact professional maintenance personnel, who have more professional tools and knowledge

    Q: Why is it so important? For us non-professionals;

    Answer: Because it can teach us a systematic way of thinking, so that we will not panic when encountering problems, and can analyze and try to solve them according to certain logic, rather than just saying "bad! Bad!"… Many times, the time and money saved are considerable, and we can also learn more about the equipment we use.

    Although the last personal opinion is called "generic", it is not omnipotent. After all, some deep hardware failures still have to be handled by professionals. However, for most of the minor problems and troubles we encounter in daily life, this set of ideas and methods is really practical. Practice more, practice makes perfect, and you will be more relaxed when you encounter problems in the future! Remember, patience and meticulousness are the key to successfully troubleshooting, but don’t give up when you encounter any difficulties!

  • Problems In Enterprise Network Transformation: How To Choose SD-WAN Solutions?

    SD-WAN is a very trendy thing in modern network architecture, and it really makes many companies worry about network transformation and don’t know how to choose. To be honest, SD-WAN is a solution that can integrate the scattered network links under the enterprise, such as broadband, 4G/5G, dedicated lines, etc., and then use software to intelligently manage them, making the network more flexible and more useful. Some people may think this thing sounds unfathomable, but in fact, it involves real points such as how to improve network efficiency, reduce costs, and make management simpler.

    Now that enterprises use SD-WAN, they can summarize it into three main aspects: First, they want to make the network more flexible, don’t be so rigid, and can quickly adapt to the changing needs of business; second, they must want to spend less money on the network, and no one wants to throw the money out in vain, right? Third, I hope that network management can save some trouble, and there is no need to arrange for a bunch of people to stare at those cold equipment every day. Provide global procurement services for weak current intelligent products! To achieve these goals, when choosing SD-WAN, you must disassemble the following modules clearly and study them!

    1. Link optimization module : The function of this module is to allow different links to cooperate well, and don’t fight~ It will see whether each link is smooth, fast or not, and then divide the data into the most suitable link in real time. For example, if a business like video conferencing that requires particularly high speed requirements, it will give priority to those stable and fast links, while those who are not in a hurry like ordinary file transfer can take cheaper broadband links.

    2. Network security module : Although we don’t need to talk too deeply about security, we still need to have the most basic firewall functions, data encryption, etc.; otherwise the data will be lost and peeked by someone, and that will be done. If an enterprise encounters such a thing, it will be more upset.

    3. Intelligent management module : This is a good helper to help administrators save trouble! It can clearly display the situation of the entire network on one, and it can be seen at a glance which device has problems or which link is slower. It can also support remote configuration of equipment, without the need for administrators to run to each computer room to operate

    There is another point that users are particularly prone to confusion, that is, what is the difference between SDWAN and traditional VPNs? Simply put, traditional VPNs are like opening up a dedicated path from home to company. Although it is safe, the road is thin and you can only walk that path; SD-WAN is like opening up multiple paths at the same time, some are wide, some are narrow, some are fast, and some are slow. It can also automatically choose the most suitable path to walk according to what you want to transport. Doesn’t it sound much more advanced? This is their main difference

    Q: Is it necessary for small and micro enterprises to use SD-WAN? A: It depends on the situation! If the company is very small, with only one or two office locations and the network is simple, then there may be no need to spend this money; but if the company has several branches, or often requires employees to work remotely outside and the business is relatively complicated, then when you go to SDWAN, you can clearly feel that the network is much more useful, and in the long run, the savings may be more than the investment.

    Q: Which function of SDWAN should be paid attention to when choosing? A: I think the most important thing I need to pay attention to is its intelligent route selection function! If this function does not work and the data always follows those blocked links, the network experience will definitely not be good. If you spend money, you will be angry. It is not worth it.

    In my personal opinion, SD-WAN is indeed a very important direction for the future development of corporate networks and can bring many tangible benefits to enterprises. When choosing, companies must not blindly follow the trend. They must listen carefully to their actual needs and find solutions that match functions, cost-effectiveness, and reliable after-sales service. You can’t just listen to which one is better. The one that suits you is the best!

  • AR Experimental Equipment Is Too Hot! Use Guide And Experience Sharing Of Pit Avoidance Experience, Read Quickly

It is the kind of technology that can mix virtual things with reality, and cleverly combines the bottles, jars and instruments used in experiments – a set of novel operating tools created! What can it do? Tsk, there are too many! For example, it can simulate a particularly dangerous chemical reaction process so that you can see clearly without worrying about being blown up; it can also lead you to disassemble a 3D three-dimensional model. What is the most important thing that is more than 100 times more intuitive than looking at a floor plan? It can help us beginners to familiarize themselves with various complex and high-end experimental processes, so we don’t have to worry about breaking expensive real guys because of their clumsy hands. It’s really too considerate and powerful!

    1. Hardware preparation and connection :

    Let’s talk about this hardware first. The first step to get the device is to think about the hardware! Generally speaking, you will have an AR headset that looks weird like glasses, and there may be several sensors used to capture your hand movements… Maybe there is a small base station for position tracking in the corner – in short, parts are indispensable. If there is any missing, you have to find the seller as soon as possible and don't guess it yourself!

    Then there is the connection, and the wire and interface can make people dizzy! Should I connect my headset and computer? The sensor must also be paired with the host? It is important to note here that the data cable interface of different brands of equipment may look completely different. Don’t force it to insert it. Use some force to see if it can’t be inserted, so stop and find out if it’s right. If the interface is crooked, it’s too late to cry! There are also some considerations in the order of booting. Generally, you turn on the computer first and then start the display after the computer is slowly started. Otherwise, sometimes it will not be connected, which is particularly anxious and annoying!

    Also, that positioning is to ensure that what you see with your eyes is accurate, which is particularly important! The room is too bright, not too dark. Some equipment also chooses a venue. There cannot be too strong reflective things on the ground, and there cannot be too many messy debris that block infrared signals. Otherwise, the picture will shake, float, and it will be dazzling. How can you do an experiment?

    2. Be patient when installing and calibrating software :

    Once the hardware is ready, it’s the software’s turn, and this thing is not a fuel-efficient lamp! Generally, the official website will provide the dedicated AR experimental software. You must see clearly that version and strictly correspond to the hardware model you bought. If the version is incorrect, it will be useless if it is downloaded. Maybe there will be security risks. Don’t just save trouble and use it!

    """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" Some options, such as "install driver" and "allow access to camera/microphone", must be checked, otherwise the software will not work normally, and you won't be able to do it at that time!

    After the installation is completed, the most important step is to calibrate! It is equivalent to "tuning your eyes" for the device and performing "space (perception) calibration" on yourself. It literally means letting the device know where you are and where you look. If this step is not done well, the virtual experiment (instrument) you see may float in the air and be crooked, or if you gesture with your hand, you will not be able to catch the virtual operating rod, which can make people anxious and angry! Follow the prompts that the robot on the screen that you don’t understand, slowly turn your head, stretch out your hand, aim at those annoying calibration points, try a few more times, don’t be afraid of trouble, it doesn’t matter if you are slow at the beginning, then it’s soon!

    3. Basic operations and common functions exploration :

    Only when the headset is comfortable can you do a good job of experimenting! Keep the elasticity well, don't always fall down like a slide – don't be too tight, so that your head hurts and you can't stand it and want to give up if you can't wear it for a while; if the lenses are dirty, you have to wipe it. Use that special soft cloth to gently rub it like a kitten. Don't rub it randomly with your greasy sleeves or cardboard shells. If you scratch the lenses, you will be finished!

    Then how do you interact with that invisible and intangible virtual object? There are generally two ways, either use your hand to gesture in the air like a martial arts gesture… or use a strange-shaped "control stick" – this one needs to be practiced more against the device and be familiar with the best angle it recognizes… Do it several times in slow motion to find the feeling, for example, "grab" usually turns your wrist slightly and stays for half a second, not just like a kitten fishing.

    There are various prefabricated virtual experiment templates in the APP, such as "basic physical and mechanical experiments", which are all practical, or if you accidentally break a virtual instrument and can reset it in one second, you don't have to worry about whether to compensate. It's simply too convenient. Provide global procurement services for weak current intelligent products! You can first start with which simplest one, follow the virtual instructor who speaks in a mechanical voice step by step. If the operation is wrong, it will usually be called. Sometimes the virtual teacher will use its emotional tone to remind you what was wrong. If you are much more patient than the real teacher, you will not scold people. After you finish it, you can still play back the steps you messed up just now. Think about why you were wrong. You will be able to get it right next time and you will know what to do! Many times, it is the truth to find experience in failure over and over again! There are many professional functions and settings. If you are not professional, it is recommended not to set parameters casually!

    Do you have any friends like me? Are you worried that the equipment suddenly ran out of power and the machine stopped working? This big problem! So once you get the charger, you have to find a fixed place to put it in. Develop the good habit of charging it casually after using it. Don’t wait until the light starts to flash red light to warn you before thinking about charging. At that time, you just happened to take the key steps. Suddenly, the crash or shutdown will make people hate it! There is also the small screen inside the headset. Don’t disassemble it and wipe it yourself. If there is dust, just find the small glue stick that sticks to dust and stick it gently, otherwise it will get worse and worse or even tear the line off. Then you should be scolded by the boss or pay for repairing it yourself! If you think an operation is particularly difficult to understand, you must actively ask questions and ask those knowledgeable friends or customer service to find out the ins and outs!

    I personally think that although this AR experimental device was particularly complicated and headache when I first came into contact with it, it was both high-tech and various buttons, which was daunting! But you only need to spend one day or two days – or take an hour more seriously, and patiently understand and understand the most basic things I said above, and then it will become more and more convenient and easier to use later. You will find that it can really save you a lot of trouble and avoid detours, and the efficiency of learning and experimental operations can also be improved by a lot – it is really worth spending time researching and mastering this little helper in the new era! It doesn’t mean that everything depends on luck, and hands-on and patience are the truth!

  • What Is Building Automation Systems? Detailed Introduction And Application Scenarios Of Building Automatic Control System

    What is it

    It is the building automatic control system we usually call; simply put, it is to connect the air conditioners, lighting, elevators, and smoke-proof subsystems in the building through various high-tech equipment and software, and then automatically control and manage such a large system. Its main purpose is to make the building more energy-saving, better managed, and more comfortable to use; now many large office buildings, malls, and hotels basically use this… By the way! Provide global procurement services for weak current intelligent products!

    What core things do they contain? Let's talk to you

    1. Hardware device part : You can score clearly

    Sensor: Temperature and humidity sensors are specifically used to detect the data of temperature and humidity in our room; there is also the light sensor that can sense whether the light outside is strong or weak. The liquid level sensor is also very important, used to monitor the amount of water in various water tanks and pools…

    Actuator. For example, electric valves can automatically switch according to the system's instructions to control the flow of water or gas; and the electric air valve is similar, but it only controls the air volume; let alone the motor controller, the operation of elevators, water pumps and other things cannot be separated from it to control it.

    Controller: This is the core of the core! DDC controllers are the most common

    2. Software system part :

    It's like the brain center – the central management stand plays a big role! Ability to collect a wide variety of data that all devices operate

    Communication network part : Without it, there is no way to "communicate" well

    Fieldbus technology: It is equivalent to the "dialogue channel" between devices

    Like a protocol, it’s as smooth as everyone speaks the same language;

    What real benefits can this bring to us?
