Generally speaking, the industrial control computer is a computer specially designed for the industrial site, and the industrial site generally has strong vibration, especially dust, and high electromagnetic field force interference, etc., and the general factory is continuous operation, that is, one year There is generally no rest. Therefore, compared with the ordinary computer, the industrial computer must have the following characteristics:
1) The chassis adopts steel structure, which has high anti-magnetic, dust-proof and impact-proof capabilities. 2) There is a special backplane in the chassis, and PCI and ISA slots are on the backplane. 3) There is a special power supply in the chassis, which has strong anti-interference ability. 4) Requires the ability to work continuously for a long time. 5) Generally, a standard chassis that is easy to install is used (2u 4U standard chassis is more common) Note: Except for the above features, the rest are basically the same. In addition, due to the above professional characteristics, the industrial control computer at the same level is more expensive than the ordinary computer, but generally it will not be much different.
Control machine box classification
IPC (Industry Personal Computer) is referred to as industrial control computer, or hard disk video recorder, DVR (digital video recording). The industrial control computer is used in a harsh environment, and has strict requirements on the ease of maintenance, heat dissipation, dust prevention, product cycle, and even size of the product. Therefore, when designing and selecting an industrial control computer platform, more consideration is given to the design of the mechanism, and then to performance considerations.
Classification of industrial control chassis:
(1) The height is generally divided into 1U (44MM * 430MM * XX), 2U (88 * 430 * XX), 3U, 4U (178MM * 430MM * XX), 5U, 6U, 7U, 8U, etc. A 1U height is 44MM , And so on at other heights;
(2) Length: There are two kinds of lengths of 450MM and 505MM according to the international standard. According to the specific requirements of customers, other lengths can also be extended, such as: 480MM, 500MM, 520MM, 530MM, 600MM, etc .; 450MM ~~ 520MM size chassis More than 90% of the market demand; the role of the extended chassis is mainly to have the following three: one is to install a dual CPU Xeon 12 "* 13" motherboard, the length must be 520MM to install such a large board; the other is to install Industrial CPU long cards or 300MM long video cards require sufficient expansion space; the last one is the consideration of heat dissipation space. Because some monitoring users need to install multiple video cards and multiple hard disks, such as 64 channels, 128 channels, etc., 10 A hard disk needs a good heat dissipation effect;
