Industrial control computer is a general term for tools that use bus structure to detect and control the production process, electromechanical equipment and process equipment. It has important computer properties and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, real-time operating system, control network and protocol, computing ability, friendly human-computer interface, etc The main categories of industrial personal computers are IPC (PC bus industrial computer), PLC (programmable control system), DCS (distributed control system), FCS (field bus system) and CNC (numerical control system). Industrial control has always been the bottleneck restricting China's equipment industry and even product upgrading. The equipment manufacturing industry is the core and foundation of industry, which determines the level of national industry and science and technology, as well as its position in the global division of labor. For industrial machines such as machine tools, as domestic manufacturers, Siemens or Mitsubishi are required to provide overall motion control solutions. Core motion control products, such as linear motors, AC servo motors and systems, which are core components or application solutions for precise motion control, are provided by foreign multinationals as a whole, and their products and technologies are designed by foreign enterprises. Domestic manufacturers engaged in machine tool manufacturing mostly understand the functions of these key components from the perspective of application, how to use them, and finally integrate them into a set of mechanical equipment. This is the gap in manufacturing and the direction of catching up.
