Industrial control automation

Industrial automation technology is a comprehensive high-tech that uses control theory, instruments, computers and other information technologies to detect, control, optimize, schedule, manage and make decisions on the industrial production process, so as to increase output, improve quality, reduce consumption and ensure safety, including industrial automation software, hardware and system. As one of the most important technologies in the modern manufacturing field in the 20th century, industrial automation technology mainly solves the problems of production efficiency and consistency. No matter high-speed mass manufacturing enterprises or enterprises pursuing flexibility, flexibility and customization, they must rely on the application of automation technology.


Automation system itself does not directly create benefits, but it plays a significant role in improving the production process of enterprises:


(1) Improve the safety of production process;


(2) Improve production efficiency;


(3) Improve product quality;


(4) Reduce the consumption of raw materials and energy in the production process.



Industrial control automation



According to the statistics of international authoritative consulting institutions, the ratio of input to output of automation system and enterprise efficiency is about 1:4 to 1:6. Especially in capital intensive enterprises, the automation system accounts for less than 10% of the total investment in equipment, playing the role of “four or two transfers of gold”. The traditional industrial automation system, i.e. electromechanical integration system, mainly controls the equipment and production process, that is, it consists of hardware elements such as mechanical body, power part, test sensing part, actuator, drive part, control and signal processing unit, interface, etc. under the guidance of purposeful information flow of software program and electronic circuit logic, it coordinates, organically integrates and integrates with each other, forming the orderly and regular movement of material and energy, So as to form industrial automation systems or products.



In the field of industrial automation, the traditional control system has experienced the development of base pneumatic instrument control system, electric unit combined analog instrument control system, centralized digital control system and distributed control system DCS.



With the development of control technology, computer, communication, network and other technologies, the field of information interaction and communication is rapidly covering all levels from the field equipment level of the factory to control and management. Industrial control machine system generally refers to the general term of automatic technical tools (including automatic measuring instruments and control devices) that measure and control the industrial production process and its electromechanical equipment and process equipment. Today, the simplest understanding of automation has also changed to: using generalized machines (including computers) to partially or completely replace or exceed human physical strength.
