Industrial control refers to industrial automation control, mainly achieved through the combination of electronic and electrical, mechanical, and software. It is industrial control or factory automation control. It mainly refers to the use of computer technology, microelectronics technology, and electrical means to make the production and manufacturing processes of factories more automated, efficient, precise, and controllable and visible.
The emergence and promotion of industrial control technology brought about the third industrial revolution, which increased the production speed and efficiency of factories by over 300%. In the early 1980s, with the spring breeze of reform and opening up, foreign advanced industrial control technology entered the Chinese Mainland. Industrial control products widely used include "PLC, frequency converter, servo motor, industrial control computer", etc. These products and technologies have greatly promoted the automation process of China's manufacturing industry and made significant contributions to China's modernization construction.
The main core areas of industrial control are in large power plants, aerospace, dam construction, industrial temperature controlled heating, ceramics, and other fields, and have irreplaceable advantages in these fields.
For example, real-time monitoring of power plants and power grids requires the collection of a large amount of data values and comprehensive processing. The intervention of industrial control technology facilitates the processing of a large amount of information.
The emergence of industrial control has improved the safety and precision of the manufacturing and construction industries, addressing industrial needs such as temperature, pressure, gas flow, and liquid flow that were originally needed. Evolve from semi-automatic and manual work to automation, including common air switches, pressure transmitters, flow meters, etc.
Working principle of industrial control: For example, the power control of air switches. When using an electrical appliance with excessive power, the internal mechanical principles start to operate, causing the switch to automatically disconnect, in order to ensure the safety of industrial or building electricity use and accurately find the source of short circuits.
