The main categories of industrial computers are: IPC (PC bus industrial computer), PLC (programmable control system), DCS (loose control system), FCS (field bus system) and CNC (numerical control system).
1、IPC
That is, an industrial computer based on the PC bus. Because of its low price, high quality, large output, and abundant software/hardware resources, it has been familiar and recognized by the majority of skilled personnel, which is also the root of industrial computer fever. Together, IPC has the characteristics of reliability, real-time, scalability, and compatibility, which can solve the problems of electromagnetic disturbance, vibration, dust, and high/low temperature in industrial sites.
Application scale: It can be connected with various peripherals and boards such as road controllers, video surveillance systems, vehicle detectors, etc. on the industrial site to complete various missions.
2、PLC
You can program logic manipulators. PLC is a digital computing operation electronic system specially planned for use in industrial environments. It uses a programmable memory, in which the instructions for performing logical operations, sequence control, timing, counting and arithmetic operations are stored, and various types of mechanical equipment or production processes are controlled through digital or analog input and output.
Application scale: It can be widely used in all aspects of industrial control, which is a huge driving force to promote the process of mechatronics.
3、DCS
That is, a distributed control system. It is a series of high-performance, high-quality, low-cost, and sensitively configured loose control systems, which can form a variety of independent control systems, loose control systems DCS, monitoring and data acquisition systems (SCADA), and can meet the needs of various industrial fields for process control and information management.
Application scale: It can be widely used in the scattered operation of various large, medium and small power stations, the transformation of the automation system of power plants, and the control of industrial production processes such as steel, petrochemical, papermaking, and cement.
4、FCS
That is, the fieldbus control system. It is an all-digital serial, two-way communication system. Measurement and control devices such as probes, actuators and manipulators can be connected, monitored and manipulated within the system. In the classification of the factory network, it is not only used as a local network for process control (such as PLC, LC, etc.) and the use of intelligent instruments (such as frequency converters, valves, barcode readers, etc.), but also has the embedded function of distributed control and application on the network.
Application scale: It has a wide range of application prospects, and there are more than 40 types of fieldbuses known in the world, and the typical fieldbuses are: FF, Profibus, LONworks, CAN, HART, CC-LINK, etc.
5、CNC
That is, the computer digital control system. It is a numerical control system that selects a microprocessor or a special microcomputer, and the system program (software) stored in the memory in advance completes the control logic, completes part or all of the numerical control functions, and connects with peripheral equipment through the interface.
Scale of application: mechanical manufacturing skills; information processing, processing, and transmission skills; Auto-control skills; servo drive skills; sensor skills; software skills, etc.
All in all, the universal use of industrial computers in the industry has become a reality, and industrial computers also play an indispensable role in the development of industrial automation.
