Daily use and maintenance of industrial computer At present, industrial computer is used in many occasions, but there are not many people who can really turn industrial computer very well. It is often seen that some people are busy for a long time and still can't troubleshoot the machine, while some people use it with ease. This difference comes from the correct management and maintenance of the industrial computer by the user. This is a little summary, I hope it can be helpful to everyone. An industrial computer is an industrial computer designed to adapt to special and harsh environments. Its power supply, chassis, and motherboard are designed to adapt to long-term uninterrupted operation. In order to use it better and keep it in good working performance, it must be properly and reasonably maintained in daily use.
First of all, it is necessary to give the industrial computer a stable working environment. If the machine vibrates while reading and writing to or from the disk or hard disk, the drive will be severely worn out or the hard disk will be damaged. If it is to be placed against the wall, there should be at least a gap from the wall to ensure good heat dissipation, otherwise, it will cause accelerated aging of components. Specifically, do the following:
1. Chassis
The chassis includes industrial control power supply, passive backplane, and fan. Industrial control power supply: It serves for N hours of uninterrupted startup, so its performance is better. The main thing to pay attention to is to minimize the entry of dust and prevent dust from affecting the operation of the fan. Prevent instantaneous power failure. Instantaneous power failure and sudden call will often generate an instantaneously extremely high voltage, which is likely to "burn" the computer, and voltage fluctuations (too low or too high) will also cause damage to the computer. Therefore, it should be equipped with a power supply as much as possible. In addition, it should also be anti-static and anti-lightning.
Passive backplane: it provides power for various boards including ,) (cards, graphics cards, sound cards, network cards, etc.), and its daily maintenance should pay attention to three points: do not dial the board when the backplane is live Do not use excessive force or excessive force when dialing the card. When cleaning the bottom plate with alcohol, be careful to prevent the tool from scratching the bottom plate. Dust should not accumulate in the slot, otherwise it will cause poor contact or even short circuit. Whether the metal feet in the slot are aligned and bent, otherwise it will affect the operation of the board in the system, which will cause various phenomena such as no display when booting, the board cannot be found, and the machine crashes. Fan: The fan in the industrial control box is specially designed for the industrial computer. It blows air into the chassis to reduce the temperature in the chassis. It should pay attention to whether the power supply is connected to the plug, and the filter outside the fan should be cleaned regularly (once a month) to prevent excessive dust from entering the chassis.
Second, the motherboard (card) industrial computer motherboard
It is specially designed for long-term operation in high and low temperature special environments. It should be noted in use: it cannot be plugged in with electricity (memory, mouse, keyboard behind the board, etc.). The holes are damaged and cannot be used, and even the motherboard will be damaged in severe cases. The jumper on the motherboard cannot be jumped casually. Check the manual or user manual, otherwise it will be damaged due to the different voltage settings of different types of motherboards. The dust on the motherboard should be cleaned regularly. Alcohol or water should not be used. Dry brushes, vacuum cleaners or leather tigers should be used to absorb or blow off the dust. Keep the memory slots on the motherboard clean and free of broken or crooked feet. The gold fingers inserted into the passive base plate under the main board should be clean, and should be firmly inserted on the base plate and inserted in place.
Three, hard disk, optical drive, floppy drive.
Hard disk: Do not disassemble the hard disk at will to avoid vibration and extrusion. Try not to turn off the power of the computer while the hard disk is running, as a sudden shutdown will cause the hard disk tracks to be damaged and data to be lost. Do not touch the jumper device on the hard disk arbitrarily. When handling, it must be packed in anti-static plastic bags or fixed with shock-proof pressure materials such as sponges, and frequently check for viruses to prevent corrosion. When there is an energy saving function in the operating system, try to use it reasonably to prolong the service life of the hard disk.
CD-ROM: Do not open the CD-ROM door at will during use. Do not use damaged or pirated CDs to prevent dust from entering the CD-ROM. Do not vibrate, distort, or beat the CD-ROM during use. The data cable should be connected smoothly to ensure that the optical drive reads the disk smoothly.
Floppy drive: Do not put bad or poisonous disks into the floppy drive, and do not use inferior and moldy floppy disks to prevent scratching the magnetic head. When the floppy drive is reading and writing to the disk (the floppy drive indicator light is on), do not forcibly remove the disk, to prevent damage to the head or offset the head, resulting in failure to read and write normally.
Fourth, various boards (graphics card, sound card, network card, etc.)
What the board should pay attention to is dustproof, the pins should be intact, the board should not be distorted when it is inserted vertically, and the connector on the outer jack of the board should not be plugged in with electricity.
The above is what you should pay attention to in the use of industrial computer. As long as you are diligent in practice and do the above points, you will manage your industrial computer system well and keep it running stably for a long time.
