Industrial Control Automation Prospect Analysis

With the continuous deepening of social information, the key tasks of key industries will increasingly rely on IPCs, and IPC-based low-cost industrial control automation is becoming the mainstream, and local IPC vendors are receiving more attention. Higher and higher. With the rapid development of electric power, metallurgy, petrochemical, environmental protection, transportation, construction and other industries, from digital home set-top boxes, digital TV, to bank teller machines, highway toll systems, gas station management, manufacturing production line control, finance, government Demand for informatization in industries such as defense and defense continues to increase, and the demand for IPCs is very large. The IPC market has a promising future.

The industrial control computer is the industrial control computer. It is a general term for the tools that use the bus structure to detect and control the production process, mechanical and electrical equipment, and process equipment. The IPC has important computer attributes and features such as a computer CPU, hard disk, memory, peripherals, and interfaces, as well as an operating system, control network and protocol, computing power, and a friendly human-machine interface. The products and technologies of the industrial control industry are very special. They belong to intermediate products and provide reliable, embedded, and intelligent industrial computers for other industries.

Development trend analysis

1. Development Trend of DCS (Distributed Control System)

Although fieldbus-based FCS has developed rapidly and will eventually replace the traditional DCS, there is a lot of work to be done in the development of Fcs, such as unified standards, intelligent instrumentation, and so on. In addition, DCS is also required for the maintenance and reconstruction of traditional control systems. Therefore, FCS needs a longer process to completely replace the traditional DCS.

Current industrial control computers still rely mainly on large systems, dispersed objects, and continuous production processes (such as: metallurgy, petrochemical, and power), and distributed control systems using distributed system structures are still in development. Due to the development of open architecture and integration technologies, sales of large-scale decentralized 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 constitute large systems to meet factory automation requirements and adapt to the general trend of openness.

(2) Towards the development of intelligence

Due to the development of database systems, inference functions, and 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 fieldbus, microprocessor-based smart devices, such as intelligent I/O intelligent PID control, smart sensors, transmitters, actuators, intelligent human interfaces, and programmable controllers have emerged one after another.

(3) Industrial PC

Due to the tendency of Gong to form this S, PCs have become common as operating stations or node machines for DCS. PC-PLC, PC-S, 19, Pc-Nc and so on are Pc-Dcs pioneers.

(4) Specialization

DCS is more suitable for the application of corresponding fields, it is necessary to further understand this professional process and application requirements, in order to gradually form such as nuclear power plant S, variable power drill DGS, glass DCS and cement DCS.
