Industrial Personal Computer (Industrial Personal Computer) is a computer specially designed for industrial sites. The environment of industrial computers should be harsh. Some good brand computers can indeed run in the same environment and may be stable, but they cannot guarantee long-term stability. In work, many industrial computers work in no-man’s land, and no errors are allowed, and stability is higher than performance. IPCs are different from ordinary business computers in the materials used for electronic components, which is also a difference in cost. The market is also different. Some of the interface requirements of industrial computers have been eliminated in current home computers, while industrial computers are more demanding and unconventional. The system architecture is not all the same, but the industrial computer has made some special designs to maintain its hardware interchangeability with ordinary commercial computers.
Industrial computer in reliability, stability, weather resistance, shock resistance, waterproof and dustproof. Anti-interference, scalability, EC compatibility and other aspects are definitely better than commercial machines. Most of the components are industrial grade or even some military grade components, so as to meet the requirements of the industrial field environment. Industrial sites generally have the characteristics of strong vibration, a lot of dust, and high electromagnetic field force interference. Generally, factories operate continuously, that is, there is generally no rest in a year. Therefore, compared with ordinary computers, industrial computers must have the following characteristics: The chassis adopts steel structure, which has high anti-magnetic, dust-proof and shock-proof capabilities. 2) There is a special bottom plate in the chassis, and there are pci and ISA slots on the bottom plate. 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) The standard chassis that is easy to install is generally used (4U standard chassis is more common). From the above characteristics of the embedded industrial computer, we can see that the market potential of the industrial computer is quite huge. The data collection work done by the embedded industrial computer is the front-end application of the Internet of Things, but most users currently only apply this information to a small range of monitoring and control, without expanding its wider range of applications, and now rely on the Internet Such a powerful basic platform can make the embedded industrial computer suitable for a wider understanding after the information is calculated and optimized.
Compared with general-purpose computers, the main features of industrial personal computers are as follows: high reliability. The industrial computer is often used to control the continuous production process, and it is not allowed to stop for maintenance during operation, and failure will lead to quality accidents and even production accidents. Therefore, the industrial computer is required to have high reliability, low failure rate and short maintenance time. Real-time performance is good. The industrial computer must respond to the changes of various parameters of the control object in real time in order to control and monitor the production process in real time. When the process parameters deviate or fail, it can respond in real time and carry out alarm and processing in real time. Usually the industrial computer is equipped with a real-time multitasking operating system and an interrupt system. Strong adaptability to the environment.
Due to the harsh environment of the industrial site, the industrial computer is required to have strong environmental adaptability, such as high requirements for temperature/humidity variation: dust-proof, anti-corrosion, anti-vibration and shock capabilities: good electromagnetic compatibility and high resistance Interference ability and high common mode rejection ability. Rich input and output templates. The industrial computer is matched with the process instrument, dealing with various signals, and requires a wealth of multi-functional input and output supporting templates, such as analog, digital, pulse and other input and output templates. The system has good scalability and openness. The flexible system expansion is conducive to the improvement of the factory automation level and the continuous expansion of the control scale. It adopts an open architecture, which is convenient for system expansion, software upgrade and exchange.
The industrial computer control software package has strong functions, with convenient interpersonal interaction, rich pictures, and good real-time performance: with system configuration and system generation functions: with real-time and historical trend recording in reality Function: with real-time and historical trend recording and display Function: It has functions such as real-time alarm and accident recall; it has rich control algorithms. The system has strong communication functions, and generally requires that the industrial computer can be turned into a large-scale computer control system, and has the function of long-distance communication. In order to meet the real-time requirements, the communication network speed of the industrial computer must be high and comply with international standard communication protocols. redundancy. In the occasions with high reliability requirements, it is required to have dual-machine work and redundant systems, including dual-control stations, dual-operation stations, dual-network communication, dual-power supply systems, dual-power supplies, etc. Software, etc., to ensure the long-term uninterrupted operation of the system.
