  • Predictive Maintenance For HVAC Systems: A Detailed Chat About Data Collection And Key Points

    Speaking of for HVAC, well…predictive maintenance is quite important for HVAC systems. Simply put, it is to collect various data and use various technical means to predict when there will be problems in the equipment, and prepare for maintenance and maintenance in advance. This can enable the HVAC system to operate stably and save some operational costs.

    Let's talk about the key things in detail below

    First, data collection. We have to collect a lot of data in the HVAC system

    1. Basic parameters like system operation. For example, the temperature is uh, what is the temperature in the room at different times; there is also pressure data to see the pressure stability, etc. The abnormal temperature is too high, which may actually indicate that the refrigeration part is in trouble; the pressure is unstable, and there is a possibility of leakage of the pipeline.

    2. What is the current and voltage of equipment, such as motors, and the current and voltage of key components? It can intuitively reflect the working conditions of the equipment. The current suddenly increases? It might be that the parts are stuck

    The second key content is data analysis. After collecting data, you have to dig through useful information.

    1. Use some methods of traditional data analysis. The data that used to run normally and now is collected is compared. If there is any deviation, the cause of deviation must be studied. Comparison of the same time period in different years.

    2. The emerging means of machine learning algorithms! Applications like neural networks can predict faults very accurately after training the model.

    Then we have to talk about pre-executing maintenance actions! Based on data analysis, we see possible failures, so let’s follow the following!

    1. Simple maintenance like parts cleaning. For example, the air filter is washed regularly. If it is not clean, it will affect the system's operating efficiency and increase energy consumption.

    2. Prepare parts replacement in advance. It is discovered that key components may end up in their lives. Then hurry up from Curry or buy new ones to replace them Hey.

    Let’s talk about some common questions in Q&A.

    Q: Predictive maintenance compared to traditional maintenance methods? Answer: Traditionally, regular and fixed processes are used to maintain, but the equipment may be well-timed, resulting in high maintenance costs; predictive maintenance is carried out using technology as needed to avoid unnecessary maintenance.

    Ask for the long term, the cost is obvious? Answer: The short-term investment in technical equipment and software costs can reduce the number of repairs in the long run and the use of parts is more efficient, and the overall cost reduction is quite clear!

    There is also a global procurement service for weak current intelligent products that can ensure that there are more high-quality choices in equipment product selection.

    In my opinion, for HVAC is definitely an important direction for future development. It will definitely greatly improve the reliability of the HVAC system and save our operators more worry. It will reassure the owners of the

  • Millennium Storage Media: How To Preserve Important Data For A Long Time, Ceramics And Crystalline Silicon?

    In discussing this – Media, that is, the medium that can store information for thousands of years. Many people are afraid that they are not very clear about how this exists. In fact, it mainly aims to preserve extremely important data for future generations, and must not deteriorate for a long time, accurately convey information to future people.

    When it comes to the millennium storage medium, first of all, from the choice of materials, some ceramic materials are one of the good aspects. This material can experience special situations such as climate change, geological movements, and environmental pollution. Still protect the information and data stored in it. Another optional material for crystal silicon. This is because it has a high durability feature and can store data in its tiny mode through precision technology to achieve a long-lasting and stable data mode.

    Let’s talk about the recording method. The optical recording method is a kind of type. For example, the use of light such as infrared laser and the special optical effect recording and reading of the media data, some microstructures are formed in this way, which is the situation of the information content itself. This method can overcome the problems caused by magnetic field interference and chemical reactions for electronic devices, etc. In terms of the new method of quantum bit recording, based on the characteristics of the special attributes of quantum recording in terms of the angle of the information level, this has high accuracy, and there is still a large data capacity and there will be many application prospects in the future.

    From a long-term storage perspective, this issue is particularly critical for environmental control in storage devices of different materials. In a relatively constant, dry and high-clean environment, try to control the temperature and humidity range, such as ±5℃ and 35% to 40%, to prevent microorganisms and dust from damaging the material. In addition, check the equipment integrity and functional conditions regularly, ensure that the data is readable and reliable at any time.

    Now, let’s explain the situation in detail through some Q&A sections.

    Q: Is it very stupid to carry ceramic memory?

    Answer: It is true that ceramics are a bit heavy and usually large in size. There are angles, but they are not so easy and flexible in carrying and moving, but the advantage is that they are very good at persistence and are very suitable for some places where they are not moved for a long time.

    Q: Is the application of qubit recording expensive?

    Answer: At the moment, because equipment and technology are still quite novel, the manufacturing cost is relatively high, and the cost will indeed be very large! After the relevant technology is proficient and large-scale investment in the market, the cost will be expected to decline from an angle.

    By talking about these, I feel that in order to preserve civilized knowledge and various important data for future generations, Media is very important. Looking at the future in a broader direction, we will undoubtedly explore more and better ways to develop. In addition, it provides global procurement services for weak current intelligent products! It can make it more reassuring to choose electronic devices and other products! I believe that in the future we will have enough technological strength to achieve a better storage method.

  • Maintenance Workflow Automation: How To Streamline Equipment Upkeep And Facility Management?

    When it comes to , a lot of folks in of and are ' their heads, ' how to make all those pesky tasks—not just fixin' stuff when it ! [But too]—run of ' like . First off, let's parse this term real slow-like: is usin' and some smart tools to take over stuff that used to be done with pen and paper, so the folks who know how to fix can focus on the hard parts, not ' !

    we dive into the , let me just slip in here—Provide global procurement services for weak current intelligent products! —in case any of you need good parts for your later on. Now, ' down the key parts of this , there's three big you gotta wrap your head :

    1. Work order & magic : of ' for to call or email some , the can kick start a work order when, say, aa 's is too high (that's ' for ya!) or when a check is due. Then, it the right based on who's free, who knows that best, and whose skill are still not —no more boss ' 'Who's ? ' the shop!

    2. & : Once the work order's out, both the ' for fixes and the tech seein' to the can check how are goin'. No more ' back and forth: "Is it done yet?" "!" "When's ?" The tech marks like 'on the way', 'parts on order' (and then the can even track those parts!), and 'fixed up'—all ' up live on a !

    3. Data ' for know-how : After all the fixin's done, [the part no one likes] the stuff like how long it took, what parts were used, how often this down at this time of year. Over time, you start seein' —like maybe the AC on the third floor acts out every —and you can fix they even !

    Now, let's some ask, 'cause I know you're ' to ask 'em:

    Q: Do we need to fire all our to do this? A: HECK no! The 's there so they stop doin' paper forms and start usin' their — would you want your best ' an hour ' a of fixin' a belt that's ' up [= money by the ? ! ]?

  • Flood-Adaptive BAS: Do You Know About The Building Automation System That Can Still Work During Floods?

    Regarding Flood-BAS ( ), it is actually a building automation system that can continue to work or protect itself when water disasters like floods occur. Do you know? There are not often unexpected heavy rainstorms in many places now. It is easy to cause floods when it rains, which has a great impact on the equipment in those buildings! So this Flood-BAS system is particularly useful for those who are easily flooded, and it is really necessary to install one!

    1. The cleverness of the system composition : there are many different parts in it, not a single thing. It's like a water-sensitive sensor. This sensor can feel whether the water has risen or whether the environmental humidity has suddenly become high. There is also a waterproof controller. The shell outside the controller has a very good workmanship. It is a special material that is tightly sealed and cannot be entered at all. In terms of (actuators), it will also be installed in a slightly higher place in advance, or cover it with a waterproof cover to avoid being soaked directly by water. The final communication module is even more powerful. It will switch to that wireless way of communication, without fear of the line being soaked.

    Provide global procurement services for weak current intelligent products! .

    2. Small details to pay attention to when installing : When choosing a device, the protection level of main (main components) must be very, very high, at least IP67 or above, and it is best to reach IP68, so that it can be safe; the installation of the equipment must also be carefully selected, and it must not be installed in low-lying areas that have been flooded in history, and it must be installed at a higher level; when wiring, those (cables) must be used with shielding and waterproof wire (wires) and the joints must be handled with special waterproof terminals, and no gap can be left.

    3. Important steps for daily maintenance : Every month, people have to arrange people to check whether the sensors can still work normally. Don’t call the alarm if they are really wet, which will be a big trouble; every six months, the shells of those controllers must be opened (of course, when the power is off, safety is the first priority!) to see if there is any moisture or dust in it. If so, clean it up quickly; every year, a comprehensive, simulated flood conditions test is carried out to see if the entire system responds quickly and accurately, and if there are any steps that have been forgotten or have problems.

    Q: So is the price difference between this Flood-BAS and the ordinary BAS?

    Answer: It must be more expensive than ordinary ones. After all, it uses a lot of materials and other materials (special), and the workmanship is more complicated! However, it is very cost-effective in the long run. If the flood really breaks the ordinary BAS, it will be both costly and time-consuming to repair. The losses caused by the failure to start the work for a long time are even greater, so this money still has to be spent!

    Q: After installation, do you no longer have to worry about floods breaking the equipment?

    Answer: It cannot be said so absolutely. Although it is very powerful and can greatly reduce the flooded risk, if you really encounter a super invincible flood that is rare in a century, and the water level is so high that it breaks through the upper limit setting, it may still be a little problem. But under normal circumstances, it can (cope with) floods, and the protection effect is already very, very good!

    I personally think that those (commercial buildings) built by rivers, lakes, or cities with relatively low altitudes should consider installing this Flood-BAS system as soon as possible. Climate change is so uncertain now that you can prevent it in advance and have no worries. This is indeed the case… I’ll give my own building insurance, how safe it is!

  • Farm Animal Tracking Is Valued, Do You Know What’s Going On And What’s The Benefit? What Should I Do?

    Regarding farm animal tracking – that is, the chickens, ducks, cows, sheep and other things we raise on the farm, we use various technical means to know where they are and what they are doing at any time. Now it is being paid more and more attention. Many friends who are engaged in breeding want to figure out what exactly is going on, what are the benefits, and what should we do! After all, if you raise this thing, you will run around and lose it. If you lose it, it will be a loss. And if you get sick and no one will find it in time, it will be contagious, and then it will be a big trouble! Therefore, the key to animal tracking is to be able to grasp their dynamics anytime, anywhere, and have some early warnings. That’s the reason!

    First of all, I have to tell you what the concept of animal tracking on this farm is. In simple terms, it means bringing a small, lightweight device to the animal. This device can send a signal. Then, through your mobile phone, computer, etc., you can see the animal in a corner of the farm at home or in the office. Whether you are eating grass quietly, walking around, or even having some minor illness or being in a state of energy, you may see a little sign through the data generated by this device! This is very useful for large-scale farms. You don’t have to run around looking for cattle and sheep with a sun hat every day, saving time and effort, and reducing labor costs! Provide global procurement services for weak current intelligent products!

    So what are the specific tracking methods? I'll talk to you, there are probably several types:

    1. The first type is the GPS tracker. This is quite common. It is a bit similar to the navigation we use for driving. It has a good accuracy. Generally, it is suitable to use it in open places, such as grazing cattle and sheep on the grassland. It can be accurate to a few meters. However, if you enter a dense forest, the signal may be almost interesting. Moreover, this thing needs to be charged, or use a battery with a very long battery life.

    2. The second type is radio frequency recognition, referred to as RFID technology, which means wearing a small ear tag or leg ring for animals, with a chip on it, and then put a card reader next to the ranch entrance and next to the feeding trough. As soon as the animal approaches, it will know that it has come. The cost may be lower than the GPS, but it can only be recognized near a fixed location with a card reader, and it cannot be seen in real time which mountain it has gone to. This needs to be clarified!

    3. The third type is newer. There are Bluetooth beacons. If you get some small signal transmitters in the farm, the equipment on the animal can measure the approximate location when it receives the signal. The distance is limited and suitable for smaller venues, such as chicken coops and pigpens. If it is too big, it will not be easy to use.

    4. The fourth type is more advanced, such as those using Beidou positioning, which is similar to GPS principles. Our country's own system has stronger signals in some areas! There is also UWB ultra-wideband technology, which will have higher accuracy, which is possible for a few centimeters, but the cost is estimated to be not low. Generally, small and medium-sized farms may not be able to use such advanced ones for the time being.

    So what are the real benefits of using this animal tracking system? What are the headaches for our farmers? Listen to me to tell you carefully:

    1. The most direct thing is of course to prevent animals from getting lost or being stolen ! In the past, when there were many animals, especially herding sheep and cattle, one less was missing when she was not careful, which made people rush around. Now, if someone has run out of the range you set, the mobile app will immediately call the alarm and send someone to find it quickly. This is so critical!

    2. Secondly, it can manage the health of animals . You think, if there is a cow that is usually lively and jumps around, today it suddenly stops eating, always lying in a place without moving, or runs to the corner to stare blankly, and the tracker on its body records its activity suddenly decreases, the system may remind you, "It seems something is wrong with this cow, go and take a look!" This will cause early detection and treatment, avoid minor illnesses becoming major illnesses, and prevent infection to other cows!

    3. It can also improve the efficiency of feeding and estrus management ! By tracking which animals eat more and which eat less, the food distribution is more reasonable. The same is true for female beasts. Knowing when they are abnormal, it may be in heat. They can mate in time, improve the pregnancy rate, and give birth to more cute calves!

    Is that suitable for everyone to make this? Not necessarily, it has to be based on your actual situation. for example;

    If your farm is just a few chickens and ducks, and it is not enough to count a slap in total, then there is no need to spend this money. You have to look at it even if you squint your eyes; if you raise hundreds or thousands of pigs, or have a large flock of sheep in the mountains, you can really consider it! Then you have to think about whether you just want to know the approximate location, or it must be accurate to a range of one meter or two meters. This determines which technology you use and how much it costs! Also, the operation method is inconvenient. The things we ordinary people use are really complicated. If you buy a system, the menu will be so loud that it will be too big to understand, and it will be useless, so the operation will be simple and clear!

    Finally, let’s ask questions and answers, maybe you still have some small questions in your mind:

    Q: Will this tracking device be uncomfortable when worn on animals? Will it affect their eating and sleeping

    Answer: Don’t worry, the equipment is now very small and lightweight, and the materials are also chosen for the kind that is not easy to cause allergies or injuries to animals. It is usually worn on the ears, legs, or on the neck like a small collar. The elasticity can be adjusted. As long as it is not a shoddy product made of particularly inferior quality, letting the animals adapt for two days, it will basically be like not wearing it!

    Q: Do the country have any regulations to comply with when using these tracking technologies? Should I apply for a license or something?

    Answer: Regarding this law and regulation issue! Generally speaking, if we wear trackers for our animals in our own farms, as long as we don’t use special frequencies that interfere with aviation, military, etc., it’s like we usually use a walkie-talkie, and there’s no big problem. You basically don’t need to apply for a particularly complicated license. Of course, if you want to import the kind of very high-end or large-scale use, it is best to ask the local agricultural department or radio management department in advance to feel at ease!

    I personally think! This farm animal tracking technology is definitely a good helper for modern agricultural raising, which can make breeding more scientific and worry-free; investment is definitely a little, but in the long run, the savings and increased income can basically be made back, and even a lot more money! Therefore, you can study and study according to the size, type of your farm and the budget you have in hand, and choose the most suitable plan for you, so that you can benefit from it early!

  • How To Upgrade Office Space Technology In The Post-epidemic Era? These Questions Need To Be Clear

    Hello everyone, let’s talk about the things called technology in office spaces in the post-epidemic era. Nowadays, not everyone pays attention to resuming work and production. How to upgrade the technical equipment in the office and how to make it more convenient and efficient for everyone to go to work? This is a big thing that many bosses and workers are concerned about! Many people actually have many questions like me about whether these new technologies are easy to use, whether they can really help everyone, and how to choose them.

    First of all, we have to explain the meaning of "office technology in the post-epidemic era". Simply put, in the days after the end of the COVID-19 pandemic, the various things used in the office make work easier and everyone's communication smoother. You can also pay attention to the health and safety of computer software, machinery and equipment. For example, video conferencing tools that allow people to have meetings without actually gathering in the same room, remote office systems that allow people to work in their own homes or elsewhere, or even smart access controls that don’t have to touch them in and out of the office. These are all! Provide global procurement services for weak current intelligent products!

    Let’s break it apart one by one and talk about the key things here:

    1. Key points for selecting remote office collaboration tools : Many companies now have employees working from home or working in a mixed office situation, so it is too important to find a useful collaboration tool. You think, if you have to use email to send a file to slowly, and if you still can’t hear clearly during a meeting, then your work efficiency will be low! When choosing, we need to look at some points: First, can many people make a document at the same time, just like several people building blocks around a table; second, the quality of the video drawing is clear and the sound is smooth, don’t hold a meeting and hold a "guessing conference"; third, is it safe, and the secrets of other companies are accidentally leaked!

    2. Office smart hardware update suggestions : In addition to computer software, the hardware you can touch and see in the office must also be replaced. Like that clock machine, did you have to press the screen with your hands before? In the future, you can change to a person who swipes his face or brushes a professional card to get in. It’s so hygienic! There is also a projector in the conference room, which can be replaced with a smart whiteboard that can be hand-written and drawn, and can also directly save the content to the computer and send it to everyone. It is so convenient!

    3. Key tricks to speed up network optimization : No matter how great the software or the hardware you use, if the company's network always loses its chain, it will be useless! So we need to find professionals to see if the company's Wifi coverage is wide enough, which corner of the signal is particularly weak; and whether the broadband speed is fast enough, and whether it can hold everyone to hold video conferences and send large files together.

    4. Application of employee health data monitoring technology : Although the epidemic has passed, everyone still cares about health. You can install a temperature detector at the door of the company and automatically measure it when you enter the door without having to wait in line; you can also think of ways to monitor the air quality of the air conditioner in the office to ensure that the air you breathe is clean!

    5. Data security protection measures reminder : If you use more new technologies, you will have more company information, customer information and other things stored in your computer, so you must not be careless about security issues! It has to be a firewall that can identify whether there are bad people trying to steal things, and also add password locks to important files, and the small setting that employees can automatically blacken the screen when they leave their seats, which is also very useful!

    Let's answer a few small questions that someone might ask:

    Q: Do small companies have a small budget and must buy so many new things?

    Answer: That doesn’t mean you have to buy everything! Small companies can choose the ones they are most anxious to use first, such as building a basic remote meeting software to increase the Internet speed… step by step, without spending a lot of money at once

    Q: Are there any new changes in these technologies now compared to when the epidemic broke out before?

    Answer: Yes! Nowadays, many AI technologies are becoming smarter and can help organize meeting notes and answer some common questions, just like a "robot assistant" following you; unlike before, many of them have to do it themselves.

    Q: What should I do if my employees are not good at using these new ones?

    Answer: It’s very simple! The company can organize some simple training to find people who know how to use it, or make a booklet or take a short video to put it there so that everyone can learn when they have time. Take your time at the beginning, just be familiar with it

    I personally think that in the post-epidemic era, the company will spend more time on these office technologies, which will not only make everyone more comfortable and energetic to work, but will actually make the company appear more and more powerful, so that it can retain people's hearts and do things better!

  • Is Plant-based Air Quality Reliable? Introduction To How Plants Improve Air Quality And Procurement Services

    Plant-based air is actually to use those green plants that can breathe to help make the air around us cleaner and better, so that we can easily inhale a breath of less impurities, and provide global procurement services for weak current intelligent products! Many people are also worried about whether this plant's formaldehyde removal and harmful effects are reliable or not, and whether it is really useful.

    First of all, we have to talk about why plants can improve air quality, not that they can make tricks out of thin air. Some plants have many small fur on the surface of the leaves, and some also have a mucous membrane on them, just like the sticky palms of the child playing with. They can stick small particles floating in the air, like dust or something, and prevent them from floating around and tossing people. There are also some more savage plants with magical "chemical plants" in their bodies – those enzymes and other things in the cells. They can quietly transform the harmful gases that sound scary, such as sulfur dioxide, benzene, formaldehyde, and other scary sounds, into nutrients they need for their own growth, or simply turn them into non-toxic water and carbon dioxide to exhale. Isn't it quite amazing?

    If you want to rely on plants to help improve the air quality at home or office, choosing the right plants is a big problem. You can't just grab a pot and put it in, that's not possible. The following plants are considered "Little Air Guardians" that have been practiced by everyone and have a good reputation. You can focus on it:

    1. The tiger-tail orchid is lying lazily there. It can absorb formaldehyde, and this guy has a big advantage. It has a good temper and is particularly drought-resistant. If you forget to drink water for it for ten days and half a month, it can live stubbornly and strongly. For those who often travel on business and have bad minds, they always forget things and water the flowers. This is simply great.

    2. Green ivy, this thing can be seen everywhere in the balcony, living room, and room, just as vibrant as the irresistible Xiaoqiang! This guy doesn't seem to have no ability. He can absorb formaldehyde and benzene, and can also increase the moisture in the house, so that the air will not be so dry and uncomfortable. Moreover, it grows fast or not, and can survive by cuttings. It can take root, sprout and grow into a pot if it is pinched or thrown into water. It is simply a good friend for beginners.

    3· Ivy, this little guy has green leaves, beautiful and small serrated edges. It has a surprising effect on pollutants such as toxic formaldehyde, filter benzene and xylene. It is especially suitable for helping with some work in a new house that has just been renovated and has a strong smell.

    4. Spider plant, its slender leaves will droop shyly. From a distance, it looks like a green waterfall. It can decompose carbon monoxide emitted from the air and formaldehyde. Moreover, this guy is more capable than ordinary plants and can work hard to perform photosynthesis in weak light. It is never as delicate and troublesome as other plants.

    It is not completely good enough to just work hard to choose the right plant variety. You have to think about the details of the placement. It is not that you can just put it anywhere.

    If the lighting conditions of the room are brighter, such as sunlight can shine through the windows near the window with clear and wide view, then it is definitely correct to place plants that like light and wilt if they lack sunlight, such as the cactus family, and the succulent plants that like sunlight.

    If the room has a dim and gloomy light, such as a corridor or a pitiful bathroom corner, you have to choose plants that can withstand coolness and cannot survive without strong light. For example, the green ivy seems to be OK to this point, the tiger skin orchid, and the elegantly named Yile orchid can barely support and maintain growth in this environment.

    There are also some common questions about plants purifying the air, and everyone will guess it. Here we also say:

    Question: Do you buy more and more powerful plants, and the number of different kinds of expensive, rare and rare plants, and the air at home will definitely be as clean as in the forest.

    Answer: This idea is not right! It is okay to say that plants purify air is an auxiliary method and can play a certain role, but if you have to treat it as the only and most important air purification solution and give up other methods, that would be a big mistake! If the formaldehyde concentration in the room exceeds the standard and exceeds the standard to a terrible level of tolerance, relying on a few pots of honest plants to suck it hard there, it would be a drop in the bucket, solve a small number of problems, and fundamentally solve the problem to meet the ideal standards required for safe stay and activities inside. The correct step at this time should be to open the window and ventilate vigorously, let the air undergo convection and exchange, and then work with a professional air purifier. The plants are placed next to them just add icing on the cake, slightly increase the effect and comfort. You can't put the cart before the horse.

    Q: Will you compete with me for oxygen when you put a lot of plants in your bedroom at night, and make people and plants lack oxygen?

    A: Most plants do absorb oxygen and release CO2 at night, which is correct. However, two special players, such as Cactus and Piran, will absorb CO2 and release oxygen at night, which is good for the respiratory system. Therefore, you can put a few less pots of them, the "night oxygen champion" plant, in the bedroom, which can not only help purify the air, but also do not have to worry about the fresh oxygen that can't exhale when fighting with people. But you can't put too much. Think about it, the room is full of dense green and tall plants, which is not a big deal, it's depressing to look at it, right?

    Personally, I think that keeping a few pots of green plants at home or in the office can not only make you tired of your eyes, relax and relax your mood, relieve stress, but also help improve and improve air quality. It can be said that several big happy events will come at the same time, which is a good thing to kill two birds with one stone. However, you must remember that plants are just auxiliary means. Cleaning frequently, opening windows every day to ventilate and maintaining air circulation is the most fundamental, basic and effective long-term way to make the air quality better, no doubt about it!

  • Voice-controlled Curtains Are Popular, And The Core Composition And Purchasing Key Points Are Revealed

    In recent years, voice-controlled curtains , as a new category of smart homes, have been widely loved by people pursuing convenient living; this type of voice-controlled curtains is like Xiao Ai? Tmall Elf? Or the product that can open and close the curtains independently by sending voice commands on the mobile app does bring unexpected convenience to daily life…

    Voice control curtains, as the name suggests, are just to pull them without hands! Instead, it is a new species that relies on speaking and using sound to direct the movement of curtains; its core structure mainly involves an intelligent control module that can receive and "understand" human words – this thing is like the brain of a curtain, and a motor running around pulling the curtains, as well as a communication unit connecting each part like a Bluetooth module or WiFi module; of course – the basic accessories such as curtain fabric must also be considered a complete set!

    1. Key points for disassembly : As the absolute main force, the motor must choose the kind that runs so small that it is almost inaudible, and it rotates steadily and does not sway. The power size should be carefully calculated based on the weight of your own curtains. When choosing communication methods, if the signal coverage of the home router is high, the WiFi version is quite suitable. If you want to use it more stable and do not occupy the home network resources, the protocol may be a better choice.

    2. Collection of installation tips : Before installation, be sure to use a ruler to accurately measure the length of the curtain track and the flatness of the installation wall. If the drilling position is offset by a slight deviation, it may be installed in a crooked manner! When you first use the network connection, you have to get the smart speaker and curtain controller closer, and wait patiently for the pairing prompt to sound before you can let go without any regularity – about every two months? Add a little lubricant to the motor rotation shaft to make it live longer

    3. Guide to solving common problems : After shouting for a long time, the curtains remain motionless. It is likely that the network signal will become weaker when it reaches the window. Try moving the router closer or equiping a signal amplifier to the curtain controller? Sometimes, the controller's "brain" suddenly becomes confused. Poke a small reset hole behind its butt, and re-pairing it and networking can usually return to normal.

    Q: I already have ordinary electric curtains at home, can I directly transform and upgrade them to voice control?

    Answer: In most cases, it is possible! Go online to buy a separate voice control module that is suitable for the existing motor model, and follow the instructions to wire and match and set it step by step, so that the old curtains can be "reborn" and have new functions. However, before modification, it is recommended to ask the customer service of the module to confirm compatibility.

    Q: If the voice command is wrong or vague, will the curtains get angry and move?

    Answer: The voice control technology is still quite smart now. Generally, you can understand Mandarin that is not very standard. For example, "close the curtains for forty percent" and "close the curtains" may be executed; however, if the accent is too heavy or the commands are too outrageous, it may be "silly and unresponsive". Just say it clearly at this time!

    The voice-controlled curtains of some miscellaneous manufacturers on the market became "dumb" and were out of control after using them for less than two months. They were greedy for cheapness and were both upset and expensive! You still have to identify those brand products with good reputation, and the quality and subsequent technical support are more guaranteed!

    Personally, I think that although voice-controlled curtains cost a little more, they provide global procurement services for weak current intelligent products! But the feeling of elegance and freedom that brings without having to use hands or mouth can control light and shadow is completely worth it! What is worth owning

  • What Are Brownfield Retrofit Tools? How To Use It? There Is Practical Experience Here

    Regarding this thing, many workers who are not aware of it and those who are new to this field will have a headache. They don’t know what it is, what it can be used for, and how to use it so that it will not be in vain! Today I will talk a few words, all of which are really hard-working, some rough but useful practical experiences. I hope I can help you, don’t dislike it! It refers to the technical updates and transformation of existing and old factories, buildings, or industrial facilities, making them powerful, saving some money or environmental protection. To put it bluntly, it is a bunch of tools, materials, methods and steps of how to do things, and the sets used to modify these projects.

    Provide global procurement services for weak current intelligent products!

    2. Don’t miss core components (knock on the blackboard! Write it down) : There is usually a checklist for old equipment, just to see if the machine parts inside can still be used; there is also an energy-saving effect calculator software, such as calculating how many kilowatt-hours of electricity can be saved with a new motor; the compatibility test manual is also very important, don’t install the old and disagree with each other! Engineers can quickly guide documents when they get started, this is so friendly to novices…

    3. The steps are not messy (I told you that I can’t eat hot tofu in a hurry! Just follow the steps!) : First go to the site to see the bottom of the sky, record all the equipment models and parameters in each corner, and create a file. Then talk to the boss and the operator about what they want to change to and what they have to achieve! The goal is to enter the data obtained into the suite system to analyze the problem, and arrange the plan in the order of first and last; afterwards, start installing new sensors, replacing old parts, and debugging the algorithm model; if the old equipment refuses to cooperate with the new system, set up a adapter device according to the compatible processing module in the suite to plug in the middle!

    1. About the price: Don’t just look at how much a kit costs, but think it’s cheap? In the later period, the annual technical support fee, upgrade package, and parts and consumables are secretly added up sometimes more than the money you bought! When selling, you have to give a preliminary estimate of the total cost of five years.

    2. About after-sales service: Be sure to ask clearly, if half of the installation system is paralyzed, or if you encounter one that you have never seen before? The fault, technical support can be solved by small answering the phone within two hours, and when can someone be sent to solve it? Don't delay the construction period and make money

    Question: I have used some equipment in the factory for almost ten years and the manual has been gone. Is it impossible to use that to change it? I can only smash it and replace it with it? Answer: Of course… there is a way to change it! Those kits generally provide photo comparison libraries for old models. If you take a photo with your mobile phone and upload it, you may be able to recognize the approximate year and conventional transformation methods. The kit really doesn't work. There is also an external signal detector in it and just clip it to the motor junction box to analyze which performance declines and falls behind during operation; if it is too broken, you can only replace it with new ones, you will ask the seller to report the selection of old and new comparisons and let them deal with it.

    Personal opinion: When choosing a kit, don’t listen to the brand’s praise for being high-end and smart. Just choose the right equipment that is common in your circle with good compatibility. The operation screen is simpler and you can teach migrant workers to click the screen a few times to operate and see the data. The key point is that the more functions the more likely it is to have problems, and it is even more troublesome to fail to fix them later! The most important thing is not to use it in one factory. Go to the factory next door to see the same type of equipment and ask what kind of kits he installed to use! Is there any place that people regret buying? These experiences are a hundred times better than listening to sales!

  • What Is The Integration Of Classroom Recording And Broadcasting System? How To Operate? What Are The Benefits? Do You Know?

    In the process of rapid advancement of educational informatization today, (classroom recording and broadcasting system integration) has become an important means for schools and training institutions at all levels to improve teaching quality and realize resource sharing! Many teachers and school administrators actually have a lot of questions about what the system integration is, how to do it, and what are the benefits of it…

    Simply put, it is to capture the teacher's teaching content in the classroom, such as what the teacher said, PPT demonstration, blackboard writing, and student interaction, through special hardware equipment and software systems, and then combine and implement a complete set of technical processes that are processed, stored, transmitted and shared. It is not a single thing, but a process of many devices and software together! This integration is not just about connecting the camera and the computer, it involves many technical details and steps!

    To do a good job, you have to disassemble these key modules step by step:

    The first step is to figure out the requirements analysis and system planning. It is to know what schools or institutions want to use this recording and broadcasting system? Do you just want to simply record and save the archive, or do you want to have live broadcast interaction? Are there any particularly high requirements for clarity, such as whether it needs 720P, 1080P or even 4K? What should I save the recorded stuff? If you don’t want to understand these basic questions, you will definitely have to work on them for a long time and are not satisfied!

    The second step is that the selection and layout of hardware equipment are very critical. This includes the camera – how many channels are suitable for the camera? A fixed or a rotary gimbal? Audio acquisition equipment is also very important. How can the microphone be used to listen to the teacher and students' voices clearly without noise? There are also core processing equipment such as recording hosts and encoders, which can keep up with the performance, otherwise it will be troublesome if it gets stuck while recording! Oh, by the way, I almost forgot the monitor or the big screen. When the teacher teaches, he has to see how he recorded it, right?

    The third step is the selection and deployment of the software system. Software is so important, it is the soul! Including recording software, editing software, management platform, and a system for post-sharing and publishing. These software must be compatible with each other, so don’t be able to open the software with this recording format! Some software also have intelligent tracking functions, which can follow the teacher to automatically adjust the camera. This function sounds quite fancy!

    The fourth step is system construction and connection debugging. Install the hardware selected in the front according to the planned location, and the lines are neatly and safely arranged, and then connect them all through software configuration to let them work in a coordinated manner. This step is very careful. Which thread end is loose or which setting is wrong may cause the entire system to be difficult to use. Try recording a paragraph to see if the picture is clear, the sound is coherent, and whether there is any delay… all these have to be adjusted a little bit!

    There may be some common questions about everyone:

    Q: After the recording and broadcast system is integrated, is it very troublesome to maintain? Do you need specialized technicians?

    Answer: Well, it depends on the complexity of the system. Generally speaking, the current system is designed to be more user–, which is simple daily maintenance, such as cleaning up equipment dust and checking whether the connections are loose. Teachers or IT administrators who know a little about computers in the school can do it with a little training. If you encounter a major failure, it may still require manufacturer or professional technical support. However, choosing a reliable brand and service provider will save you a lot of worry when maintaining it!

    Q: Can the recording and broadcast system be integrated with other existing teaching systems in the school, such as video conferencing systems, online learning platforms, etc. be used? Will there be conflicts?

    Answer: In most cases, interconnection can be achieved. The key is whether compatibility is considered when planning the system in the early stage. Many manufacturers' recording and broadcast systems provide open interface standards, such as APIs. If you want to connect from the beginning, you can ask integrators to dock and develop well. After the docking is done, flexibility and practicality will be greatly increased, but this will also increase the complexity and cost of integration!

    I personally think it is a very valuable investment for modern education. It can not only help students review and make up for lessons after class, but also provide teachers with materials for teaching reflection, promote teachers' professional development, and most importantly, it can preserve high-quality teaching resources and benefit more people. Although the whole process sounds a bit complicated and there are many things to consider, as long as you follow the steps, step by step, and choose the right products and services, you will definitely be able to do it!
