Industrial control refers to industrial automation control, which is mainly realized by the combination of electronic, electrical, mechanical and software. That is, industrial control or factory automation control. It mainly refers to the use of computer technology, microelectronic technology and electrical means to make the production and manufacturing process of the factory more automatic, efficient, accurate, controllable and visible.

All steel case

The all steel chassis of IPC is designed according to the standard, anti impact, anti vibration and anti electromagnetic interference. The passive backplane compatible with PC bus can be installed inside.

Passive backplane

The slots of the passive backplane are composed of bus expansion slots. The bus expansion slot can be composed of multiple slots of expansion ISA bus, PCI bus, PCI-E bus and pcimg bus according to the actual application of the user. The number and location of expansion slots can be selected according to the needs. However, according to different pcimg bus specifications, there are requirements on the combination of various buses. For example, pcimg version 1.3 bus does not provide ISA bus support. The board has a four-layer structure, and the middle two layers are the ground layer and the power layer respectively, This structure can reduce the mutual interference of logic signals on the board and reduce the power supply impedance. The backplane can be plugged with various cards, including CPU card, display card, control card, I / O card, etc.

Industrial power supply

In the early days, industrial personal computers before Intel Pentium processors mainly used at switching power supply. Like PC computers, ATX power supply was mainly used, with an average trouble free operation time of 250000 hours.

CPU card

There are many kinds of CPU cards in IPC, which can be divided into long card and half long card according to the size. Most of them are desktop system processors, such as 386 \ 486 \ 586 \ PIII in the early stage, and P4 and core dual core processors are the mainstream. Mainboard users can select and match them according to their needs. Its main characteristics are: working temperature 0-60 ℃; With hardware "watchdog" timer; Some embedded CPUs that require low power consumption are also required.

Other accessories

Other accessories of IPC are basically compatible with PC, mainly including CPU, memory, graphics card, hard disk, floppy drive, keyboard, mouse, optical drive, display, etc. The standard length of industrial control cabinet is 19 inches and the height is 4U.

Applicable fields:

IPC has been widely used in all aspects of industry and people's life. For example: control site, road and bridge control and toll collection system, medical instruments, environmental protection monitoring, communication support, intelligent traffic control system, building monitoring and security, voice call center, queuing machine, POS counter cash register, CNC machine tool, fuel dispenser, financial information processing, petrochemical data collection and processing, geophysical exploration, field portable operation, environmental protection, military industry, electric power, railway, expressway, aerospace, subway, intelligent building Outdoor advertising, etc.

Industrial control features

Generally speaking, the industrial control computer is a computer specially designed for the industrial site. The industrial site is generally characterized by strong vibration, especially much dust, and high electromagnetic force interference. Moreover, most factories operate continuously, that is, there is no rest in the year. Therefore, compared with ordinary computers, industrial control computers must have the following characteristics:

1) The chassis is made of steel structure and has high anti magnetic, dust-proof and impact resistance.

2) The chassis has a dedicated backplane with PCI and isa slots.

3) There is a special power supply in the cabinet, which has strong anti-interference ability.

4) It is required to be able to work continuously for a long time.

5) Generally, the standard chassis that is easy to install (4U standard chassis is common) Note: except for the above features, the rest are basically the same. In addition, due to the above professional characteristics, the price of industrial computers at the same level is more expensive than that of ordinary computers, but generally there is not much difference.

Disadvantages of industrial control computer although industrial control computer has unique advantages compared with ordinary commercial computer, its disadvantages are also very obvious -- poor data processing capacity, as follows:

1) Small hard disk capacity;

2) Low data security;

3) The storage selectivity is small.

4) The price is high.
