Application
Industrial automation technology is a kind of use of control theory, instrumentation, computer and other information technology to realize detection, control, optimization, scheduling, management and decision-making of industrial production process, so as to increase production, improve quality, reduce consumption and ensure safety. Comprehensive high-tech, including three parts of 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. Whether it is a high-speed mass manufacturing enterprise or an enterprise pursuing flexibility, flexibility and customization, it must rely on the application of automation technology.
The 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 the production process;
(2) Improve production efficiency;
(3) Improve product quality;
(4) Reduce raw material and energy consumption in the production process.
According to the statistics of the international authoritative consulting organization, the investment in the automation system and the increase in the output of the enterprise benefit ratio are between 1:4 and 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 thousand dollars". The traditional industrial automation system, that is, the mechatronics system, mainly controls the equipment and the production process, that is, it consists of hardware elements such as the mechanical body, the power part, the test sensing part, the actuator, the drive part, the control and signal processing unit, and the interface. Under the guidance of the purposeful information flow of software programs and electronic circuit logic, they are coordinated, organically integrated and integrated to form an orderly and regular movement of matter and energy, thereby forming an industrial automation system or product.
In the field of industrial automation, the traditional control system has experienced the development of base-type 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 the control and management levels. Industrial control machine system generally refers to the general term of automation technology tools (including automatic measuring instruments and control devices) that measure and control industrial production processes and their electromechanical equipment and process equipment. Today, the simplest understanding of automation has also been transformed into: using machines in a broad sense (including computers) to partially replace or completely replace or surpass human physical strength.
Industrial automation is one of the most important directions for the application of automation technology. Its specific applications include:
Computer-aided design (CAD) and computer-aided manufacturing (CAM) Integrated office automation (OA) (for example: access control system, IT audit) Process control and automation instrumentation artificial intelligence technology. The advancement of automation technology has promoted the rapid development of industrial production, especially in petroleum, chemical, metallurgy, light industry and other industries. Due to the use of automated instruments and centralized control devices, the development of continuous production process automation has been promoted, and labor productivity has been greatly improved. The method of managing the chemical production process with automated devices is called chemical automation.
