The development of modern production and science and technology puts forward higher and higher requirements for automation technology, and also provides necessary conditions for the innovation of automation technology. After the 1970s, automation began to develop towards complex system control and advanced intelligent control, and was widely applied to various fields such as national defense, scientific research and economy, to achieve more large-scale automation, such as the integrated automation system of large enterprises, the national railway automatic dispatching system, the national power network automatic dispatching system, the air traffic control system, the urban traffic control system, the automatic command system National economic management system, etc. The application of automation is expanding from engineering to non-engineering fields, such as medical automation, population control, economic management automation, etc. Automation will imitate human intelligence to a greater extent. Robots have been applied in industrial production, ocean development and space exploration, and expert systems have achieved remarkable results in medical diagnosis and geological exploration. Factory automation, office automation, home automation and agricultural automation will become an important part of the new technology revolution and will develop rapidly.
