Intelligent control is formed on the development of computer technology. Embedded humanoid intelligent control system has excellent self-organization and self-adaptation capabilities, and has good performance in large-scale complex industrial system control. With the development of instruments and meters, instruments and meters have penetrated into all fields of people’s life and become an important tool for human beings to acquire information, understand nature and transform nature. Now the development level of instruments and meters is an important symbol of the development level of modern science and technology. Programmable logic controller (PLC) is a kind of digital operation and operation control device. It is an electronic system developed instead of the traditional relay, which integrates computer technology, communication technology and automatic control technology. Embedded humanoid intelligent control system has superior self-organization, self-adaptive and self-learning ability. The arithmetic operation function and data processing ability of PLC are greatly enhanced, which makes the realization of complex control algorithm on PLC possible.
