PLC teaching system based on configuration software, control method and application

Abstract

The invention discloses a PLC teaching system based on configuration software, a control method and a traffic control system. The PLC teaching system based on configuration software comprises a programmable logic controller, the configuration software, a database and a communication service unit, wherein the programmable logic controller outputs control signals; the communication service unit changes corresponding variable values in the database according to the control signals; an analog display image on a display interface of the configuration software displays a corresponding image according to the variable value in the database. When the method is applied to simulation of the traffic control system, the changes of traffic lights at a crossroad can be displayed visually on the configuration software, understanding of a material object by a student is enhanced, and the student can combine field practice while the PLC theoretical knowledge is learnt.

Description

technical field [0001] The invention relates to a PLC teaching system, in particular to a PLC teaching system based on configuration software, a control method and an application thereof. Background technique [0002] PLC is a programmable logic controller (Programmable Logic Controller), which is widely used in various industries such as steel, petroleum, electric power, automobile, transportation and culture and entertainment. From these industries, it can be seen that the application field of PLC belongs to high temperature Explosive, high-risk production and other fields, and these fields have relatively high professional requirements for operators. At present, the process of learning in colleges and universities is only through classroom teaching program instructions, which are difficult for students to understand, let alone the cultivation of skills such as programming, debugging, and wiring. Therefore, the knowledge of some mechanical objects such as valves, motors, ...

AI Technical Summary

Problems solved by technology

At present, the process of learning in colleges and universities is only through classroom teaching program instructions, which are difficult for students to understand, let alone the cultivation of skills such as programming, debugging, and wiring. Therefore, the knowledge of some mechanical objects such as valves, motors, pumps, sensors, etc. is very lacking

[0003] Commonly used configuration software is mainly used in industry to monitor the workflow of some large-scale equipment, and is rarely used in the teaching field, such as simulating actual projects, etc.
