With the continuous deepening of social informatization, the key tasks of key industries will increasingly rely on industrial computers, while low-cost industrial control automation based on IPC is becoming the mainstream, and local industrial computer manufacturers have also received attention. taller and taller. With the rapid development of electric power, metallurgy, petrochemical, environmental protection, transportation, construction and other industries, from digital home set-top boxes and digital TVs, to bank teller machines, highway toll systems, gas station management, manufacturing production line control, finance, government , national defense and other industries informatization demand is increasing, the demand for industrial computers is great, and the development prospects of the industrial computer market are very broad.
Industrial tablet computer is an industrial control computer, which is a general term for tools that use a bus structure to detect and control the production process, electromechanical equipment, and process equipment. Industrial personal computers have important computer attributes and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, as well as operating systems, control networks and protocols, computing power, and friendly human-machine interface. The products and technologies of the industrial control industry are very special and belong to intermediate products, which provide reliable, embedded and intelligent industrial computers for other industries.
Development Trend Analysis of Industrial Panel PC
1. The development trend of DCS distributed control system
Although the FCS based on the field bus develops rapidly and will eventually replace the traditional DCS, there is still a lot of work to be done in the development of the Fcs, such as unifying standards, intelligent instruments and so on. In addition, the maintenance and transformation of traditional control systems also require DCS, so it will take a long process for FCS to completely replace traditional DCS.
At present, industrial computers are still dominated by large systems, decentralized objects, and continuous production processes such as metallurgy, petrochemical, and electric power. The distributed control system using the distributed system structure is still developing. Due to the development of open architecture and integrated technology, sales of large distributed control systems have increased.
1. To develop in a comprehensive direction
Due to the development of standardized data communication lines and communication networks, various single and multi-loop regulators, PLCs, industrial ratios, NCs and other industrial control equipment form a large system to meet the requirements of factory automation and adapt to the general trend of openness.
2. Develop in the direction of intelligence
Due to the development of database systems, reasoning functions, etc., especially the application of knowledge base system KBS and expert system ES, such as self-learning control, remote diagnosis and self-optimization, artificial intelligence will be implemented at all levels of DCS. Similar to the FF field bus, intelligent devices based on microprocessors, such as intelligent I/O intelligent PID control, intelligent sensors, transmitters, actuators, intelligent human interfaces and programmable regulators, appear one after another.
3. Industrial PCization
Since it has become a major trend to form this S, PC has become very common as the operation station or node machine of DCS. PC-PLC, PC-S, 19, Pc-Nc, etc. are the pioneers of Pc-Dcs.
4. Specialization
In order to be more suitable for the application of DCS in various fields, it is necessary to further understand the process and application requirements of this profession, so as to gradually form such as nuclear power plant S, substation drill DGS, glass DCS and cement DCS.
