PCB Technical - PCB industrial control computer PCB copy board

1. Definition of industrial computer:

PCB industrial computer is an industrial control computer, but nowadays, the more fashionable name is industrial computer or industrial computer, referred to as IPC in English, and the full name is Industrial Personal Computer. In layman's terms, industrial computer is a computer specially designed for industrial sites.

2. The main structure of the industrial computer:

1. All-steel chassis

IPC's all-steel chassis is designed according to the standard, anti-shock, anti-vibration, anti-electromagnetic interference, and can be installed with a passive backplane compatible with PC-bus.

2. Passive backplane

The slot of the passive backplane is composed of multiple slots of ISA and PCI bus. The number and location of ISA or PCI slots can be selected according to needs. The board has a four-layer structure, and the middle two layers are the ground layer and the power layer. This structure can reduce the mutual interference of logic signals on the board and reduce the power supply impedance. The backplane can be plugged into various boards, including CPU cards, display cards, control cards, I/O cards, etc.

3. Industrial power supply

is an AT switching power supply, with an average trouble-free running time of 250,000 hours.

4. CPU card

There are many types of IPC CPU cards, which can be divided into long cards and half-length cards according to the size, and can be divided into 386, 486, 586, PII, PIII motherboards according to the processor, and users can choose and match according to their needs. Its main features are: working temperature 0-60 degree Celsius; equipped with "watchdog" timer; low power consumption, the maximum is 5V/2.5A.

5. Other accessories

Other accessories of IPC are basically compatible with PCs, mainly including CPU, memory, graphics card, hard disk, floppy drive, keyboard, mouse, optical drive, monitor, etc.

3. Features of industrial computer:

In layman's terms, industrial computers are computers specially designed for industrial sites, and industrial sites generally have strong vibrations, particularly dust, and high electromagnetic field interference. In general, factories operate continuously, that is, throughout the year. There is usually no rest. Therefore, the industrial computer must have the following characteristics compared with ordinary computers:

1) The chassis adopts steel structure, which has high anti-magnetic, dust-proof and impact-proof ability.

2) There is a dedicated backplane in the 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.

4) The ability to work continuously for a long time is required.

5) Generally use a standard case that is easy to install (4U standard case is more common)

Four, industrial computer PCB copy board:

IPC copying can also be said to be IPC clone, IPC imitation, IPC circuit board copy. The general method is to first disassemble the industrial computer, drive out its internal control board and all circuit boards, and then rely on professional copy board technology to copy out these circuit boards and PCBs one by one, and send the resulting file diagrams to the PCB manufacturing board. After the factory manufactures the boards, all the circuit boards will be cloned completely according to the purchased components list. After that, rely on professional software designers to carry out software programming of the working principle of the industrial computer, and then assemble and weld the fax machine in the production and processing plant, and then it can be debugged and tested. This process can clone the most advanced fax machine in a short period of time, greatly reducing its price.
