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.

Industrial control has always been a bottleneck restricting China’s equipment industry and even product upgrading. The equipment manufacturing industry is the core and foundation of industry, determining the level of national industry and technology, as well as its position in global division of labor.

For industrial motherboards such as machine tools, as domestic manufacturers, Siemens or Mitsubishi need to provide overall motion control solutions. The core components or application solutions for precise motion control of core motion control products such as linear motors, AC servo motors, and systems are provided by foreign multinational corporations as a whole, and from products to technology, they are designed by foreign enterprises. Domestic manufacturers engaged in machine tool manufacturing mainly understand the functions of these key components from an application perspective, how to use them, and ultimately integrate them into a set of mechanical equipment. This is the gap and direction of catching up in the manufacturing industry.
