Industrial automatic control system

Abstract

The invention discloses an industrial automatic control system. The system comprises an output switch quantity control, a proportional integral derivative control, a single-chip microcomputer module,a sensor module, a signal amplification module, and an A / D conversion module. The output switch quantity control controls the state of the output to be switch on or off by comparing a deviation of a given value from a controlled parameter. The output control quantity has only two states, so that the rate at which the controlled parameter changes in both directions is the largest, and the feedbackloop is easy to oscillate. The structure of the industrial automatic control system is scientific and reasonable, and the use is safe and convenient. The system is a typical closed-loop control systemand the purpose of the control is power regulation. The system controls the characteristics of a thyristor through a single-chip microcomputer technology, thereby controlling the magnitude of the voltage and finally controlling the electrical power. The system also has a feedback device, which performs detection through a sensor detection technology, and provides feedback to the control portion of the single chip microcomputer after processing and the feedback is displayed through a display portion.

Description

technical field [0001] The invention relates to the field of industrial automatic control technology, in particular to an industrial automatic control system. Background technique [0002] Industrial automation is the trend of widely using automatic control and automatic adjustment devices in industrial production to replace manual manipulation of machines and machine systems for processing and production. Under the conditions of industrial production automation, people only indirectly take care of and supervise machines for production. Automation, according to its development stage, can be divided into: (1) semi-automation, that is, part of the use of automatic control and automatic devices, while the other part is produced by manual operation machines; (2) full automation, referring to all processes in the production process, including Loading, unloading, loading and unloading, etc. do not require people to directly perform production operations, but the machine continuous...
