The power supply of the industrial control LCD screen belongs to the structure of the industrial control computer. The industrial control computer is a very special product. Next, I will introduce you in detail what is the industrial control power supply and the maintenance knowledge of the industrial control power supply.
What is industrial power supply?
The industrial computer is structured by bus, for electromechanical equipment and production process. The industrial computer has computer attributes and features, such as computer memory, CPU, hard disk, peripherals and interfaces, and has an operating system, control network and protocol, friendly human-machine interface, and computing capabilities. The technology and products of the industrial control industry are very special and belong to intermediate products. They provide embedded, reliable and intelligent industrial computers for other industries.
How should industrial power supply be maintained?
1. Large voltage fluctuations and power outages: With the development of industry and the improvement of living standards, the demand for electricity is gradually increasing. Some remote areas are prone to insufficient power supply and unstable voltage. As a result, the industrial control system often restarts, and some important log files of the system are easily lost, resulting in failure to start normally. Therefore, the stability of the power supply in the working environment of the industrial computer is related to whether the industrial computer is working normally. Need to use stabilized power supply and UPS uninterrupted power protection, the specific equipment selection needs to be determined according to the magnitude of the negative power and the amount of maintenance working time.
2. There are a lot of inhaled particles in the air: most of the raw materials in the factory need to be processed by powder. In addition to the large flow of air outside and more sand and dust, it is easy to gather a large amount in the industrial computer. Dust causes the temperature inside the industrial computer to be too high and damages the hardware. This situation generally occurs around cooling fans such as power supplies, CPUs, graphics cards, and hard drives. Where there is less dust, regular dust blowing can be used if normal production permits. Where there is a lot of dust, you can use the ventilated place of the industrial control cabinet to install the dust filter gauze and then need to clean it regularly.
Fourth, the ground has a greater sense of vibration: Many factories require motors to generate physical displacements such as drag and vibration during the production process, which not only bring huge noise, but also the vibration caused by the machine when it is working. Industrial computer optical drives, floppy drives, and disks cause huge damage. The technology of disk production is also getting higher and higher. In the automated control system, large amounts of data exchange, long-term, high-speed operation of the disk, it is easy to cause the disk's read and write ability to drop rapidly due to disk vibration, the disk positioning is slow, and even the disk may be damaged; therefore, it will reduce the number of industrial computers. The environmental shock is conducive to protecting the disk.
