An automatic control method and device

Abstract

The embodiment of the invention discloses an automatic control method and device, and the method and device are used for an industrial automatic control system. The method comprises the steps: creating a script execution function module, compiling a script corresponding to the script execution function module based on a target control strategy, determining an input parameter corresponding to an input pin of the script execution function module, and outputting an output parameter corresponding to an output pin; creating a reading function module, and determining an output parameter corresponding to an output pin of the reading function module; enabling the output pin of the reading function module to be correspondingly connected with the input pin of the script execution function module, so as to enable the output parameter corresponding to the output pin of the reading function pin to be matched with the input parameter corresponding to the input pin of the script execution function module; determining the logic sequence of the executing of the reading function module and the script execution function module, and executing the reading function module and the script execution function module according to the logic sequence, so as to control the control system according to a parameter outputted by the script execution function module. The method and device achieves a purpose of reducing the possibility of wrong modification.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to an automatic control method and device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In order to save energy and increase efficiency, reduce production costs and maximize profits, production enterprises have an increasingly urgent need for optimization of production conditions and refined operations. Advanced Control (Advanced Control) is currently the most effective technology for working condition optimization and fine operation. The so-called advanced control is a general term for those control strategies that are different from conventional single-loop control and have better control effects than conventional PID control, rather than specifically referring to a certa...
