Industrial automation control is referred to as industrial control. It is mainly realized through the combination of electronic, electrical, mechanical and software. Industrial control or factory automation control. It mainly refers to the use of computer technology, microelectronics technology and electronic means to make the manufacturing process more automated, efficient, precise, controllable and visual.
The emergence and popularization of industrial automation control technology has brought about the third industrial revolution, which has increased the production speed and efficiency of factories by more than 300. In the early 1980 s, with the spring breeze of China's reform and opening up, overseas advanced industrial control technology began to enter the mainland of China. Widely used industrial control equipment such as "PLC, frequency converter, AC servo motor, industrial computer", these products and technologies have greatly promoted the automation process of China's manufacturing industry and made great contributions to China's modernization.

The main core areas of industrial automation control are large power plants, aerospace, dam construction, industrial temperature control and heating, and ceramics have irreplaceable advantages.
For example, real-time monitoring of power grid needs to collect a large number of data values and carry out comprehensive processing. The intervention of industrial control technology facilitates the processing of a large amount of information.
The emergence of industrial automation control has improved the safety and accuracy of the manufacturing and construction industries, and solved the industrial needs of temperature, pressure, gas flow, and liquid flow. In the original need to use semi-automatic and manual work conditions into automation, mainly including ordinary air switch, pressure transmitter, flow meter, etc.
The working principle of industrial automation control: such as the power control of the air switch, when the electrical power is too large, the internal mechanical principle starts to run, causing the switch to automatically disconnect, so as to ensure the safe use of electricity in the industry or building, and accurately find the short circuit source.
