The industrial computer is generally a computer specially designed for the industrial site, because the industrial site is more complicated and dusty, and many industrial sites still have strong electromagnetic fields that interfere with the normal operation of the machinery. The operation of the industrial computer is generally 24 hours a day. There are no interruptions for hours, and so on throughout the year. Therefore, the industrial computer as a computer must have its own special functions. What are the performance requirements of the industrial computer? (The domestic famous industrial computer brands are: EVOC Industrial Computer, Qingdao Industrial Control)
Compared with the general computer, the industrial computer must have the following characteristics:
1. The industrial computer chassis adopts steel structure, which has high anti-magnetic, dust-proof and anti-strike capabilities.
There are dedicated backplanes in the two chassis, and there are PCI and ISA slots on the backplane.
3. There is a special power supply in the chassis, and the power supply has strong anti-interference ability.
Fourth, it is required to have the ability to work continuously for a long time.
Five, generally use the standard chassis that is easy to install (4U standard chassis is more common) Note: In addition to the above characteristics, other basics are similar. In addition, because of the above professional characteristics, the cost of the same grade of industrial computer is more expensive than that of ordinary computers, but generally not much difference.
Compared with the disadvantages of industrial computer and general computer:
Disadvantages of current industrial computers Although industrial computers are compared with ordinary commercial computers, they have many advantages listed above, but there are advantages and disadvantages, and their shortcomings are also obvious, that is, the ability to process data is poor, as follows:
1. The construction hard disk capacity is small;
2. Low data security;
3, the storage selectivity is small.
4. Higher cost
Analysis of common problems and countermeasures of computer mastering in typical industries
One of the most common problems in computer control in typical industries: What should you do if your keyboard and mouse can be operated normally, but suddenly fail one day?
Reply: 1. Confirm whether the keyboard lock of the industrial computer is accidentally locked, please exclude the keyboard lock;
2. Please confirm whether the continuous line of the keyboard and mouse is consistent with the keyboard and mouse port of the motherboard.
Question 2 is often seen in typical industry mastering computers: after the industrial computer is powered on, the power output status indicator light on the passive backplane will turn off once it is on. What should I do if it cannot be powered on?
Reply: 1. Confirm whether there are metal foreign objects such as screws in the YONGS industrial computer, which may cause a short circuit;
2. Confirm whether the relevant power wiring system in the industrial computer causes a short circuit to ground;
3. Please accept the alternative method to try to replace the power supply of the same specification;
4. If it still cannot be powered on, please contact the factory immediately.
Question 3 is common in typical industries to master computers: YONGS industrial computer does not start after booting, but can hear the beeping alarm sound for a long time, what should I do?
Reply: 1. Confirm whether the memory stick and the motherboard are continuous and reliable;
2. Check whether the gold finger of the memory stick is dirty;
3. Use an eraser to polish the golden fingers of the memory stick and try;
4. Try changing the memory stick to another memory slot;
5. Use the alternative method to try to replace the memory stick of the same specification.
Question 4 is common in typical industries to master computers: What should I do if the YONGS industrial computer is in a state of restarting after it is turned on?
Reply: 1. Please confirm whether the RESET button of the hard reset of the industrial computer is continuously in the state of forced startup
2. Please restore the hard reset button to the normal state.
