The industrial computer industry display has quickly confused all walks of life in the trend of the situation, and the development trend of the industrial display is getting better and better, and there are more and more varieties, so the development of the industrial display can be predicted. , can continue to bring joy and benefits to every industry!
The industrial indicator is the indicator used in the industrial control process or construction. The main difference between it and civilian or commercial displays is that the shell design generally adopts an all-steel design, and the panel is divided into different materials such as ordinary iron plate, stainless iron, stainless steel, aluminum panel, etc., special design of dustproof and shockproof, suitable for industrial use High-level LCD display, in the case of high environmental requirements, consider adopting a wide temperature (-40 to 85 degrees) LCD display, currently only a small number of large international manufacturers manufacture such displays, and the cost is more expensive. The protection grade of the industrial display is indicated by IP**, the former is the dustproof grade, and the latter is the waterproof grade. Dust rating up to 6, waterproof up to 8.
For such nursing care is:
Generally, the following aspects must be done:
1. The surface of the computer should be kept neat: although do not place items on the machine, it should be waterproof, dustproof and oil-proof.
2. All related power transformers and UPSs should be opened to prevent the temperature from being too high and causing the industrial integrated computer building to burn out.
3. Clean the industrial integrated computer on schedule, remove dust and stains.
4. The continuity of the power cord should be safe and unchanged, and it is not allowed to arbitrarily dispatch the industrial integrated computer and disassemble the internal devices.
5. After the industrial integrated computer is powered off and shut down, it should be turned on at least one minute later, although it should not be turned on and off frequently.
Introduce how to check when the industry monitor finds a problem!
1. The whole machine of the industrial display has no electricity. This is originally one of the most simple obstacles. Generally, there are two types of power supply in the industrial display power supply, the internal power supply and the external power supply, and the external power supply is more common. Regardless of the type of power supply, its layout is much simpler than the power supply for CRT monitors, and the vulnerable components are a few small components, such as fuses, input inductors, switch tubes, and Zener diodes. The more common problem is that the power supply does not start caused by the CPU of the motherboard. This situation is actually very simple, that is, through the keying board to the CPU, and then through the CPU outputting a control signal to drive the power supply and change the integrated circuit work.
2. The industrial display indicator of the industrial computer will not light up once it is on, but the power indicator light is always on. This kind of problem is mostly caused by high voltage, which belongs to the circuit protection operation. In this case, there is usually a performance on the LCD screen, and the key to seeing is "strabismus". The point of the test is to compare the complement method. Because, the design of the high-voltage board of the industrial display generally adopts a symmetrical design, and there is basically no damage to both sides at the same time. The step-up transformers and lamps are the ones that are easy to cause problems in the old machine, and the guard circuit and process problems of the new machine are relatively many.
3. The bright lines of the screen are probably the dark lines, which are usually the hindrances of the LCD screen. The bright line hinders the continuous wiring of the LCD screen body, and the dark line is usually the main body of the screen. The above two problems are basically the death penalty for the industrial display device. Fees are too high.
4. Problems such as blurry screen or white screen are mainly caused by the drive voltage of the display screen. If the drive circuit of the display screen is on the motherboard, it should be an obstacle to the motherboard. If the drive circuit of the industrial display is on the LCD screen, In this case, the display screen should be replaced, and the after-sales harm is also great.
5. The color cast hinders the general process of after-sales mediation mode.
The most prominent uses of industrial display devices are: machines that can be embedded in industrial sites, cabinets, or placed on consoles, as man-machine display operation interfaces, as bedside service terminals and outpatient terminals in digital hospitals, and to improve hospital services. No and management level.
