1. There are many inhalable particles in the air: most of the materials in processing plants require granular materials for production and processing. In addition, the external gas flow is high, and there is a lot of wind and sand. It is easy to accumulate a large amount of sticky dust inside the industrial control computer, leading to excessive temperature in some parts of the industrial control computer and damage to the hardware configuration. This situation often occurs around fans such as CPUs, switch power supplies, computer hard drives, and independent graphics cards. Local areas with light dust accumulation can be blown using the concept of time with the consent of all normal production. In areas with severe dust accumulation, a vacuum cleaner principle sandcloth can be installed in the ventilation area of the industrial control cabinet, which needs to be regularly cleaned.
2. The working voltage of the power supply system fluctuates greatly and is easily cut off: With the development of industrial production and the improvement of living standards, the demand for electricity is also expanding day by day, and some relatively remote areas simply manifest as insufficient power supply systems and short circuits. The industrial automation management system often restarts, and important log files of the management system are lost, making everything unable to start normally.
Therefore, in the natural environment of industrial computer operation, the stable connection of the switching power supply is related to whether the industrial computer operates normally. The maintenance uses on-demand adjustable regulated power supply and UPSups power supply, and the actual selection of machine equipment model depends on the output power and continuous operation time of the load.
3. Inappropriate relative humidity of the air: Industrial control computers are composed of integrated circuit chips of many electronic components, and the function of their insulation layer is closely related to the relative humidity of the air. High environmental humidity can easily cause circuit board short circuit faults and damage; If the ambient humidity is too low, electrostatic induction is likely to occur, and some electronic components will also penetrate. Therefore, if the environmental humidity is too high or too low, it will pose a potential threat to the industrial control mechanism. For the safety protection of electrostatic induction, we must have a good instrument panel grounding device on the IPC.
4. High ground vibration: Many processing factories require motors to produce physical deviations such as drag and vibration, which not only generates significant noise, but also the vibration generated by equipment operation can cause significant damage to industrial computer disks, computer optical drives, and floppy drives. The processing technology for disk production is becoming increasingly advanced. In many data transmission in the mechanical automation management system, the disk is only impacted by the disk when it runs at a high speed for a long time, leading to the decline of the disk's reading and writing ability, the slow positioning of the tape drive, and even the disk is damaged. Therefore, it reduces the natural environmental vibration of industrial control computers, which is beneficial for disk maintenance.

It is understood that finance and security are currently the main application fields of facial recognition technology in China. At present, many airport security systems use facial recognition technology, such as the recently popular airport facial recognition, which is a huge market in the field of airport security. In fact, not only public places such as train stations, airports, and schools have their own layouts, but there will be more demand in the future. The incremental monitoring space is huge, and the application prospects of face recognition are broad.
In addition, facial payment has become very popular in the financial field, and relevant departments will introduce financial standards related to facial recognition, clarifying the security management requirements for facial information collection, transmission, storage, and utilization. However, facial recognition devices are also used. Why are some used for high-speed rail security checks and some for facial brushing? Let's start with the hardware and software algorithms for facial recognition. Generally speaking, 3D face recognition is relatively strict in authentication, which mainly uses 3D structured light, TOF and other face cameras to measure 3D face information such as eye spacing, nose height, etc.
At the same time, we also need to look at its application scenario, which is to use facial recognition terminals for recognition and corresponding number of people for recognition. This can be divided into three modes of facial recognition: 1:1 mode, 1: N mode, and M: N mode.
1: 1 mode, mainly used for one-on-one identity recognition scenarios, such as facial payment, hotel check-in, exam identity verification, and witness ratio matching. The user must stand still for a few seconds in front of the facial recognition terminal, and then verify their identity through the facial recognition camera to prove that 'you are you'. Due to the application scenarios where face payment, hotel check-in, exam identity verification, and witness comparison require a real name registration system, a person's mistake may bring risks. Generally, the recognition accuracy must reach over 99% in order to ensure accurate identity correspondence.
1: The N-mode is mainly used for one-to-many face recognition scenarios. It's about finding the person you're looking for from N faces and discovering who you are. The company's facial recognition attendance is also independently searched through facial recognition devices from the company's internal facial database to determine whether you are a company employee before you can open the door and release. For example, if the police want to find fugitives recorded in the database from densely populated areas, they need to filter out matching individuals from a large amount of information in the facial database. This model tests the capacity of the portrait database, with an accuracy slightly lower than the 1:1 model by 5% -10%.
M: Here, N mode 3354 can be understood as a database. M: The N-mode is often used in places with high traffic and the need to ensure public safety. For example, in train stations, concerts, and large-scale sports events, when performing facial recognition, the recognized subject usually does not stay in one place and is in a state of motion. It belongs to dynamic recognition and is easily affected by side, light, distance, and other factors. In face of face recognition scenarios with large amount of data, edge computing may be required through face recognition terminals to reduce the burden of the database background.

Meeting doorplates are ubiquitous in our daily lives, and can often be seen in office spaces such as meeting doorplates. The conference house number is a management platform that combines the conference house number machine with the conference reservation system software. It replaces traditional house numbers and has powerful functions. In addition to displaying the house number, conference room name, time, etc., conference room reservation management can also be carried out. The conference room can be reserved through web pages, mobile phones, and other means, and synchronized to the electronic doorplate all-in-one machine screen to achieve intelligent conference management.
The conference doorplate system is a conference management system composed of people and computers that can collect, transmit, store, maintain, and use information. The integrated conference door number machine is a device used for displaying information such as conference room schedule, conference theme, conference time, and attendees in front of all conference rooms in enterprises. Improve the efficiency of meeting room usage, solve common problems encountered in daily life, and utilize meeting room space resources.
There are various viewpoints and theories regarding the definition of the value of conference house numbers. We will only discuss it from two aspects: functionality and attributes, without delving into it. Function refers to the function of something. When considering purchasing a conference reservation system, we will consider our own needs, which may only come from a point that we cannot accept. For example, I cannot accept someone accidentally or intentionally breaking in during a meeting. Whether he knows he is in a meeting or not, it will disrupt my meeting status. So I want a method or tool to maintain order in the conference room. Let me make an analogy from an objective point here, I want to solve it. I entrusted this issue to the person in charge. The person in charge understood and discussed various methods and came up with several solutions: walk to the door, hang a sign, stand at the door, and notify all employees of the company to be in place. Some of these methods are indeed effective, but they don't feel that way. When we discovered a tool for conference booking, we were pleased that it was very suitable. After finding and obtaining a quote, we found that pricing was a new issue. It takes so much budget to solve this small demand, and I feel that there is a deviation between price and value.
For most situations: value and need, need and value. The value and price are equal again, which is also a deviation between demand and price, and it does exist. Here we consider a question; Attributes are divided into general attributes and attributes. Common attributes are the same basic functions, the basic needs of most customers, and the basic necessary conditions for the existence of goods; The unique attribute is based on this. paranoid. The starting point of the conference reservation system comes from the Internet of Things, creating an intelligent office platform and changing the office environment. Although it has basic functions, it is more like an artwork in an office environment. This is a new work mode that carries the innovative concept of the company. When customers or teams come to the company to visit and communicate, this is also the label of the company. With a business card, you will also receive more recognition and recognition. This is its unique attribute. In the long run, a one-time investment will benefit you and you will not see more returns. The impact it brings to the company is also profound and long-term. So when considering him, please believe in your own thoughts and choices, this is the future trend.
