电力拖动课PLC实验系统设计

电力拖动课PLC实验系统设计(论文15600字)
摘  要
在人类对自然界规律的探索和认识过程中，科学实验是必不可少的一个重要环节，可以说没有实验也就没有现代科学。因而现代可编程序控制器教学不只是单纯教授学生理论知识，更应加强学生实际动手能力的锻炼。
基于此，本课题是在实验箱基础上开发电力拖动课PLC自动控制综合实验系统，工作台上配有主机，可编程序控制器通过与上位机接口联网。实现用交流接触器、继电器、指示灯或实物模拟被控对象，模拟工业控制现场。
可编程序控制器原理及应用课程的特点是可编程序控制器原理部分内容较抽象，应用部分与生产实践紧密结合，实践性教学环节占有较大的比重。通过实践性教学环节，学生不仅可以加强对可编程序控制器理论的理解，而且也掌握了先进的控制技术，达到更好的教学效果。

Abstract
The laws of nature in the human exploration and understanding of the process, is essential for scientific experiments an important part, we can say no there is no modern experimental science. Thus the teaching of modern programmable controller is not simply to teach students theoretical knowledge, but should strengthen students' practical ability to exercise.
Based on this, the subject is developed on the basis of the experimental box PLC automatic control electric drive class integrated experimental system, with a host table, programmable logic controller interfaces with the host computer through the network. Implemented by AC contactors, relays, lights or physical simulation of the controlled object to simulate industrial control field.
Features Programmable Logic Controller Principles and Applications course is part of the programmable controller more abstract principle, the application of part of the production practices closely, practical teaching occupies a large proportion. Through practical teaching, students can not only enhance the understanding of the theory of programmable controllers, but also mastered the advanced control technology to achieve better teaching results.
