PLC _ Automation Control System _ 1 _ Automation Control System in short

I have mentioned some texts about the SCL Of The SIEMENS Automatic Control System some time ago. I suggest you briefly introduce the automatic control system here. Here I will give a brief introduction, in fact, we often see automated control in our daily lives.

Systems, such as our crane-type elevator and crawler elevator, are applications of automated control systems. Let's make a simple analysis of this, so that friends who are engaged in computer science in the garden can have a perceptual knowledge of the automatic control system.

An automatic control system, as its name implies, is a system that can run automatically. It consists of control objects, control cores, and auxiliary control components, from refrigerators at home to EMUs and high-speed trains, from cutting-edge to aerospace control, automation control is indispensable.

System. From the perspective of simplicity, the automated control system consists of detection components, control components, execution components, and man-machine interfaces. If the automatic control system is compared with the human body, the detection component is equivalent to the human eyes and ears.

It detects external information. The control component is like a human brain. It makes a comprehensive judgment and processing of the information detected by the detection component to obtain certain logical results; the execution part is like a person's hand and foot. The execution part is made based on the logical result obtained by the control part.

The corresponding action. The man-machine interface is equivalent to a person's mouth or hand-written word. The man-machine interface displays the status information of the executed part to people. The following is a brief description of the automatic control system.
