可编程控制器的教学探讨

The Thinking of the Programmable Logic Controller Teaching

针对"电工技术"课程中可编程控制器这一章教学中存在的实际问题,提出具体的解决措施。采用与继电接触器系统紧密结合来引入可编程控制器,抓住典型示例介绍可编程控制器的工作原理和方式,并用对电动机的点动控制来突出讲解可编程控制器与继电接触器系统的区别。实践证明,循序渐进的理论教学与设计性实验相配合,是学生学好可编程控制器的有力措施。

In this paper,suggest and advice are put forward to the teaching of Programmable Logic Controller in the course of electrical engineering.Introduce Programmable Logic Controller with closely integration to the relay-contactor system,explain the working principle and methods of Programmable Logic Controller by typical example,and explain the difference between Programmable Logic Controller system and the relay-contractor system through the controlling to the interrupted run of motors.Practice has proved that the theory of progressive teaching and design experiments guarantee students learn Programmable Logic Controller.
