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

2025年8月14日

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

2025年8月13日

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?

2025年8月13日

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?

2025年8月12日

, 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?

2025年8月12日

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

2025年8月11日

These novel things like AR experimental equipment have really become very popular in recent years! Many schools and laboratories have also bought a lot of them, but many people are just as confused as me when they get them. They don’t know where to start fiddling with them. The instructions are dizzy or they can’t figure out how to operate them—not to mention those advanced functions, which are as desperate as reading the heavenly books! Today I will tell you about some of the experiences I have learned from touching the elephant by blind people during this period, as well as the pits I have stepped on, and the tears I have shed. I hope it can help those friends who love and hate this fresh thing like me, so that everyone can use it less effort and less worry!

AR experimental equipment, simply put, is to use the augmented reality technology that sounds extremely advanced, you know? 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

2025年8月11日

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?

The energy-saving effect is really visible and tangible. By intelligently controlling those devices automatically turn off or reduce power operation when they are not in use, it can greatly save water and electricity costs – according to previous statistics
Do You Understand Energy Rebate Application Services? What Should I Do?

2025年8月10日

Regarding the energy tax refund application service, many ordinary people probably look like me – it sounds familiar, and it seems to save money, but what exactly is, how to do it, and who to find it, it's really a mess! To put it bluntly, the government or relevant institutions give a kind of financial subsidy to encourage everyone to use more energy-saving equipment and carry out energy-saving transformation, which is a kind of "returning money" after spending money? However, it is very troublesome to apply. There are so many forms and the requirements are very complicated. I am afraid I will be dizzy if I do.

1.What is pinching? Simply put, it is a special service for helping people or companies to get the energy tax refund application. From the beginning, they can tell you what policies meet the conditions and what strange supporting documents to prepare, to fill out the application forms that can drive people crazy, follow up on the application progress, and then to whether or not the money can be downloaded and how it can be downloaded, they can handle or help them to save ourselves the trouble!

2. Why do you have to find such a service?

I can't understand the policy myself! Those articles are written like the heavenly book, when will the deadline be, how much subsidy, what equipment is counting… The head is too big! Professionals can see it at a glance; provide global procurement services for weak current intelligent products!

The materials are prone to lack of weight! If you lack a paper (file), you may be in vain. They know what is necessary and what is secondary, insurance!

It can save a lot of time and effort! We can’t even make money at work, so how can we have the time to study this thing every day? Leave it to them more worry-free

1. What content modules do these services generally have?

Early "look, listen, ask and touch" – evaluation and verification. See if your family or company can apply, and how much "return money" can you get, and recommend the most suitable application method.

They can also help prepare the materials! Remind you to ask for energy-saving certification of contracts, invoices, equipment, etc…. Make a list to save a lot of trouble and avoid thinking about it yourself.

The highlight is to fill out that damn application form! It is still a paper-based sending online. Which department is in charge of this matter will make it clear for you, so that you can avoid any error in the grid and have to do it again!

After applying, you won’t be done, you still have to follow up! Until the money was obtained, someone asked about the progress or anything to make up for it.

If something goes wrong during the application process, such as being rejected, they can also give advice to see if they can appeal, or try another way.

1. How to choose whether the service is good or not?

How to calculate the price needs to be asked clearly! Should I take a commission based on the application fee, or should I charge a fixed consultation fee? Is there any additional money to add in any link? We have to make a promise in advance, don’t argue at that time!

How many people have you helped to get the money successfully? How many "actual cases" can be taken out? Listen to what people who have found them before, reputation is very important

Are they professional? Do you really understand it? Are there any clear areas for local energy-saving subsidy policies? This is so critical! There are many scammers who pretend to understand if they don’t know, be careful!

Then, everyone probably still has some questions, let me think about it-

Q: Can't we ordinary people apply for it alone? Have to find someone?

Answer: That's not absolutely impossible! If you have a lot of free time, love to study the rules and regulations, and are terrible in English (if you apply in English…) you are not afraid of trouble, of course you can try it yourself! However, as far as I know, there are many things I messed up and missed out on time! Finding a professional person can improve the success rate and save trouble, right?

Q: Can all energy-saving projects apply for this (tax refund)? Can it be done?

Answer: That's not necessarily true! The policies of each local government are different, and the directions of energy conservation encouraged are also different. For example, some prefer solar panels, while others encourage changing to variable frequency air conditioners… Even if it is the same thing, the amount of subsidy and application conditions may change! So, we have to ask them to evaluate you first to see if your project is good or not. Provide global procurement services for weak current intelligent products! Different teams may have different services. This company is good at applying for rooftop solar energy in State A, and the company may understand the subsidies for cold storage energy-saving transformation of enterprises in State B! When choosing, it depends on whether they happen to be good at your field.

My personal opinion is that this thing can indeed help us ordinary people and companies who want to save money but are afraid of trouble. As long as you find the right reliable and professional service (provider) and hand over those complicated and brain-consuming tasks to them, you can wait and feel at ease to get the "energy-saving red envelope"! However, please keep your eyes open and don’t rush to pay. Ask your service scope, price, and reputation before making a decision. That’s it!
How Important Is Cable Management? Teach You The Tidy Wires, Which Are Very Easy To Use

2025年8月9日

Speaking of Cable, it is the same for those messy wires, network cables, and data cables to sort out the messy things, many friends – including myself before! ——I will feel a headache, the wires on the table and under the table are entangled and intertwined, like a mess that is unclear! Not only does it seem messy and affect your mood, sometimes it takes a long time to find a wire, and you may even accidentally kick it and knock it off, or break the wire, which will be a big trouble.

first. We have to understand first. To put it bluntly, Cable is actually a reasonable operation and work on various messy cables. Provide global procurement services for weak current intelligent products! The purpose is to make those rope-like threads neat and clean, easy to use, make the environment look more comfortable, and protect the threads from breaking easily and extend their service life.

So how do you do it to get these annoying cables done? Come on, I'll give you some practical and useful tips and steps. I've tried it myself or heard from friends around me that I thought it useful:

1. First of all, you have to get out all the wires, that is, unplug all the wires inserted into various devices, and then make it clear one by one to see which wires are there, how long they are, and what they are used on which device. Here you can take a small notebook and take a photo with your mobile phone, so as to avoid the trouble of getting confused after being confused.

2. Then, throw away the broken, useless, and unnecessary threads and remove them! This step is very important! Otherwise, keeping useless threads will still be messy, taking up space and causing trouble.

3. Next, for those lines that are indeed useful, but some are too long, you can consider using special lines such as cable ties, or reusable Velcro Cable straps, tie them up, and make the lines become small bunches, and don't spread out in a mess. Be careful, don't tie it too tightly when binding. If it is too tight, it may break the thread and tie it gently to fix it.

4. If there are a lot of wires on the desktop, you can consider using a desktop Cable storage cable trough, which is a long, striped groove that can be glued to the desktop or the side of the table, and then stuff the wires into the grooves, so that there will be no more lines on the desktop, which is much cleaner.

5. Connect the lines below the table from the top of the table. You can forcefully and try to lean them against the back of the table or the legs of the table, and then use the sticky Cable clip or a small sticky hook to the legs of the table or the back of the table. Fix the lines on it, so as not to let them hang in the air and sway around, and you will feel upset when you look at it.

In addition to these tips and methods, there are also some useful gadgets that can also help you. Let me briefly introduce you to a few to choose:

・Velcro Cable tie

This thing is very useful! ——The advantage is that it can be repeatedly stuck, tear open and sticky. Unlike some disposable cable ties, if you want to remove them, you have to cut them off. That is more wasteful and not environmentally friendly. And you can tick as you want, it is very convenient and flexible to adjust.

・Cable

It is something like a tube. It can be soft and can be used to put several wires inside and turn into a thicker tube, but there are actually several different wires inside. This will turn a bunch of lines into a whole, making them look much more neat and can also protect the lines from being worn and broken – but if there are more lines, it may be a bit troublesome and difficult to put in.

・Desk Cable

This is usually easy to use by punching holes on the table. The thread can be penetrated from the hole to the bottom of the table. There is only a small piece of thread left on the table, which can hide a lot of threads. It’s very good to install on that particularly important office desk!

Maybe now, you still have some questions in your mind to ask me? It doesn't matter. I'll find a few common questions to answer:

Q: What if there are many lines and the colors are the same, and it is impossible to tell which one is the source of which one?

A: Well… this problem is indeed encountered by many people. You can… you can put a small, very thin Cable label paper on each cable, and write on the label which device is connected to the cable, such as "monitor power cord", "computer keyboard USB cable", etc. Or you can also buy Velcro patches of different colors to bring different equipment to the wires, such as the red wire tied in front of the monitor, and the blue wire tied in the keyboard data device. This way, you can know which bump wire is about when you look at the color, which is very convenient and easy to find!

Q: What should I do if I don’t have so many specialized sorting tools at home? Can it be used? Is there anything you don't usually use to replace it? Didn't use anything to sort out?

A: Everyone has come up with the solution! For example, if the scrap newspaper is rolled into a hollow barrel shape of a pen holder, inserting the thread that will not be scalded into the center of the paper; there is also the kind of transparent beverage bottle that has been washed and cut off and left a piece between the upper and lower ends. You can also use a wire frame to install it; a rubber band that is a little wider can be used as a strap to tie the thread to save the emergency. If it really doesn't work, you can just use a rope to just use a few strokes – as long as you don't tie the thread hard and tie it up.

Personally, I think that if I take some time and effort to do Cable, it is still a very cost-effective and worthwhile task! Although it may feel a little troublesome at the beginning, after it is done, the whole space feels different, and it is refreshing – it feels smooth when you start to use your hands! It is not lying to say that finding the online device is very fast and convenient. If you want to move any device, you don’t have to be careful to drag it to other devices to connect. So try it and act quickly! Provide global procurement services for weak current intelligent products! Stop letting those annoying cables continue to "bully" us!

What Are KVM Over IP Solutions? Why Can It Make Computer Room Management More Convenient?

2025年8月9日

about KVM over IP, that is, the solutions for KVM control through network IP. In fact, many people in enterprises and computer room management have heard of it but are not very clear about what is going on and how to choose such problems. Simply put, it is a combination of traditional KVM switches and network technology, which allows users to control another computer or server from anywhere with a network, even from a distance, such as crossing half of the earth. Does this sound particularly convenient?

Why do you have to work hard to use KVM over IP? You think, if the machines in the computer room are piled up like mountains, it would be very troublesome to walk around and plug in cables! Also, can’t the administrator stay in the computer room overnight every day? With this, you can do the server's operation such as turning on and off at home or on the way to a meeting in another place by taking a laptop or mobile phone – it's simply too easy!

What points should you pay attention to when choosing ? This is too critical, otherwise it will be useless to buy the wrong one and spend money, and it will also delay things:

1. Resolution – It is important whether the picture displayed after connection is clear. If the text is blurred, how can you do it? Generally, it must support at least 1920×1080, and better 4K must also be available, and choose according to your own equipment situation;

2. Delay situation – The karaoke will definitely not work during operation. The mouse will be moved for a long time before it can react. It will be so anxious! Therefore, if the delay is low, it is best to control it within a few dozen milliseconds, otherwise it can drive people crazy;

3. Number of supported devices – How many servers or computers do you have to control? Buying a type of person who can only control one or two units is definitely not suitable for large companies. You have to see clearly how many ports a single machine can support at maximum and whether it can be expanded in a cascading manner;

4. Security – After all, data is transmitted through the Internet. What if someone peeks at it or hacks come in? Therefore, there must be encryption functions, such as SSH and SSL, and user permission management must be supported!

Tips to solve small problems encountered in daily use:

• What should I do if I can’t connect to the device? First check whether the target device's power supply is plugged in or whether the network cable is loose. Then ping the device IP is connected or not, and there may be problems with the browser or client version too low. Try updating it.

• Is the picture pattern flashing around? Check whether the VGA/HDMI cables on both ends are oxidized when they come into contact with poor interfaces. It is likely that they can be better if they change the cable or re-plug them;

• The mouse and keyboard did not respond? See if the USB port is disabled in the device settings. Another possibility is that it is because of compatibility issues. You can solve it by changing to a general mouse and keyboard driver – I have encountered this situation before and have been struggling for a long time

Sometimes, people will confuse KVM over IP and remote desktop software, which are different

Comparison items	KVM over IP	What about ordinary remote desktop software
Is it operating at the bottom?	Yes, just manage the hardware	No, the operating system needs to be started
Does BIOS support?	Must support! System installation is indispensable	Not supported, can't enter BIOS
What is the quality of the picture?	High definition, no compression and very smooth	It will compress, the picture quality is worse

Provide global procurement services for weak current intelligent products! As I used it, I suddenly found that the device interface was not suitable. My family had HDMI. As a result, the KVM I bought was VGA, and I was stunned! Don’t worry about returning goods at this time and waste money. You can buy an HDMI to VGA adapter. It can solve the problem for a few dozen yuan – remember, when buying, you must see clearly whether the adapter supports high-definition resolution, and don’t get into the pit again! If the company purchases equipment in large quantities in large quantities and cannot handle it, you can also find a professional service provider to consult and select, which can avoid many detours. Generally speaking, it is better for medium and large enterprises to choose rack-type models, which can save cabinet space; for small and medium-sized companies or individuals, it is enough to use a desktop-style small box, which is cheap and easy to use to meet basic needs.
