Automation is a comprehensive science and technology that involves many disciplines and is widely used. As a systems engineering, it consists of 5 units: ① program unit. Decide what to do and how to do it. ② the action unit. Apply energy and positioning. ③ sensing unit. Detect the performance and status of the process. ④ Formulate the unit. The information sent by the sensing unit is compared, and a command signal is formulated and issued. ⑤ Control unit. A mechanism for developing and regulating units of action. The research content of automation mainly includes two aspects of automatic control and information processing, including theory, method, hardware and software. From the perspective of application, the research content includes process automation, mechanical manufacturing automation, management automation, laboratory automation and home automation Wait.
