S7-200PLC在全自动洗衣机中的设计与应用

Design and Application of S7-200PLC in Full Automatic Washing Machine

本文是针对学院实训设备模块的开发,利用S7-200PLC来模拟自动洗衣机的控制过程。从PLC设备的控制流程图、I/0端口分配表、顺序功能图、梯形图及外部接线图等方面做了具体介绍,并详细分析了程序的控制过程,可以让高职院校的学生更加了解PLC的可靠性和实用性。为今后学好《PLC》这门课程和掌握洗衣机的控制过程打下良好的基础。

This paper is aimed at the development of the training equipment module, and uses S7-200 PLC to simulate the control process of the automatic washing machine. This paper introduces the control flow chart, PLC device I/0 port allocation table, sequential function chart, ladder diagram and external wiring diagram etc.in details. The control process of procedure is analyzed in details, which lets the higher vocational college students learn more about the reliability and practicality of PLC and then have the solid foundation for learning the course of "PLC" and master the control process of washing machine.
