The development of industrial automation is inseparable from industrial control equipment. With the rapid development of science and technology, equipment is constantly updated. Traditional industrial computers can no longer meet the needs of modern industries. Especially in the intelligent age, industrial computers are the core of intelligent equipment. The embedded industrial computer can better adapt to the needs of more industrial equipment. Let's first understand the structure of the embedded industrial computer.
The structure of embedded industrial computer can be divided into 5 kinds:
1. Passive backplane
The passive backplane is designed as a multi-slot backplane in the form of bus structure (input STD, ISA, PCI bus, etc.), and various functional modules, such as CPU motherboard, CRT display interface board, etc., can be inserted into the backplane slot.
The structure of the bottom plate is based on the modular design idea, which can be designed into different functional modules in the form of plate structure according to different controls to form a control system for different control objects. The backplane of personal pc is an integrated body of bus and functional modules, which has poor expansion functions (less slots), but saves space.
2. CPU card:
There are many types of IPC CPU cards. According to the size, they can be divided into long cards and half-length cards. According to the processor, they can be divided into 386/486/586, PII, and PIII motherboards. Users can choose and match according to their needs. Its main features are: working temperature 0-60℃; equipped with "watchdog" timer; low power consumption, the maximum is 5V/2.5A.
3. Industrial power supply
Industrial electricity is generally 3-phase 380 volts. The industrial power supply can start the motor and change the direction of rotation. In addition, it can also avoid excessive current and heat when using high-power electrical appliances.
4. All-steel chassis:
The all-steel chassis is designed according to the standard, shock-resistant and anti-vibration. Anti-seismic and magnetic interference, passive backplane compatible with PC-bus can be installed inside.
5. Other accessories:
The 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.
It can be seen that, compared with the traditional industrial computer, the embedded industrial computer is lighter in size, more convenient to install, easy to move, and easy to disassemble in case of failure. As the country attaches importance to intelligent manufacturing, industrial computer also plays a role. An increasingly important role.
