Industrial personal computers are generally used in places where the environment is more extreme, and the demand for information security is also higher. Therefore, industrial personal computers usually carry out unique development such as reinforcement, dust prevention, waterproof, moisture-proof, anti-corrosion, radiation protection, etc.
The senior engineer of the industrial control integrated machine manufacturer mentioned the differences in the appearance and structure of the switching power supply:
1. In terms of switching power supply, the normal industrial computer power supply is different from the ordinary switching power supply;
2. From the perspective of appearance, most of the ordinary computers are open, showing that there are many cooling holes on them, while the industrial control computer chassis is completely closed. There is not only a fan for switching on and off the power supply inside, but also an internal blower fan for maintaining the positive gas pressure in the chassis with a larger air volume; Or use fanless to prevent dust, moisture and interference;
3. In terms of internal structure, it is also different. Generally, there is only one main board on the ordinary computer, with CPU slot, memory slot and other standard parts, while the industrial computer is different. It has a large motherboard, also called passive motherboard. There are not many integrated circuits on this board, but only more expansion slots. The motherboard with CPU should be inserted in the unique slot on this motherboard, and other expansion boards should also be inserted in the motherboard, It is not on the motherboard. The advantage is that the motherboard can better protect the display screen from the influence of the outside world, because the workplace of industrial personal computer is sometimes extreme and has more influence, which can make the host work more reliably, and the large motherboard is also easier to expand other plug-ins, so that developers can have more choices when developing the operating system, without considering whether there is space to learn to put it down.
