An article to understand the difference between an industrial computer and an ordinary computer
About the industrial computer, I believe everyone understands that it is actually a kind of computer, but it is dedicated to industrial control, and it is also a computer designed specifically for industrial control.
The characteristics of industrial computer
1、The use of fully tempered industrial chassis in accordance with the "EIA" standard enhances the electromagnetic interference resistance.
2、It adopts bus structure and modular design technology. The CPU and each function module use the plug-in structure, and has the soft lock of the press rod, which improves the anti-impact and anti-vibration ability.
3、The chassis is equipped with double fans, positive pressure convection air exhaust, and equipped with a dust filter screen for dust prevention.
4、It is equipped with highly reliable industrial power supply and over-voltage and over-current protection.
5、The power supply and keyboard are equipped with electronic lock switches to prevent illegal switching and illegal keyboard input.
6、It has self-diagnosis function.
7、I/O templates can be configured as required.
8、It is equipped with a "watchdog" timer, which automatically resets without human intervention when the machine dies due to failure.
9、Good openness, good compatibility, absorbs all the functions of the PC, and can directly run various application software of the PC.
10、The real-time operating system can be configured to facilitate the scheduling and running of multiple tasks.
11、Can use passive motherboard (baseboard), more convenient system upgrade. Field of application.
The difference between industrial computer and ordinary computer
Although they all belong to computers and have roughly the same basic configuration, such as motherboard, CPU, memory, various peripheral serial and parallel ports, their technical requirements are different due to different applications. Ordinary home or office computers are civil grade, while industrial computers are industrial grade. They have special requirements for other aspects of the structure.
From the appearance, most ordinary computers are open, showing a lot of heat sinks, and only one power fan cools itself to the outside of the case. The industrial computer case is completely enclosed and much heavier than a normal computer case, indicating that the motherboard used is thicker and thicker because it is more robust. There are not only power fans, but also internal blowers to keep the positive pressure in the chassis greater. In this way, the external structure is dustproof and shielded from electromagnetic interference to the interior. A typical computer typically has only one motherboard with standard configuration components, such as CPU slots and memory slots. Others such as separate graphics cards are inserted into expansion slots on the motherboard.
Most are PCI slots these days. Industrial computers are different. It has a larger motherboard, also known as a passive motherboard. There are not many integrated circuits on the board. Just more expansion slots. The mainboard with CPU should be inserted into the dedicated slot on the mainboard. Other expansion boards should also be plugged into the motherboard, not the motherboard. This advantage is that the motherboard can be better shielded from external interference, because the workplace of the industrial computer is sometimes worse, more interference, so that the main analysis can work more reliably, and the large motherboard is easier to expand other plug-ins. In this way, designers can have more options when developing systems without having to worry about whether there is room to put them down.
As far as the power supply is concerned, the power supply of conventional industrial computer is different from that of ordinary power supply. The resistance to shock and interference of resistors, capacitors and coils used in power supplies is several levels higher than that of ordinary homes. The carrying capacity is also much greater. The CPU and memory of the fan-less industrial computer are integrated on the motherboard. Laptop hard drives are used, as well as CF cards and SSDS. Power supply generally uses 5-30V DC power supply. Industrial computer has a wide range of applications. The motion control card is inserted into the slot of the industrial computer to control the stepper or servo motor system, such as dispensing machine, winding machine, visual printing machine, SMT machine, PCB inspection machine, fast and slow line walking machine, laser cutting machine, engraving machine and other equipment. It can also communicate with industrial computers via serial ports, RJ45 interfaces and PLC modules. For example, the reflow welder of Nitto adopts PLC series PEC and TAC6000 temperature control module controlled by Dalian to control the industrial computer, and displays the operation interface, temperature curve and temperature setting through the display. Industrial computers are also used in building intelligence, safety control, fire and alarm, highways and other fields.
The industrial computer is mainly used in a professional field, such as a common monitoring machine. Then the configuration is simple and stable. Many industrial computers use dedicated chips and motherboards, like the often said single-chip chip. The ordinary computer is mainly comprehensive application, in the configuration is extensible, multi-functional.
