基于PLC的全自动洗衣机控制系统设计
摘要：目前我国洗衣机行业发展迅速，无论在技术上还是在质量上，我国的发展水平都与世界水平持平。放眼望去当下的洗衣机市场，高效节能型洗衣机在市场上占据了主导地位。因为高效节能型全自动洗衣机的特点是，节能环保，省水省电。所以它成为最受欢迎的对象。
根据全自动洗衣机的工作状态控制原理，我们利用可编程控制器PLC实现对全自动洗衣机的自动控制。为人民的生活提供更好的便利。本次设计，利用西门子S7-200系列PLC的特点，进行控制系统的设计，最终实现洗衣机的自动化。

Based on PLC automatic washing machine control system design
Abstract：Washing machine industry has developed rapidly in China at present, whether in technology or in terms of quality, the development level of our country with the world level. Look the current washing machine market, efficient washing machine occupies the dominant position in the market. Because of the characteristics of efficient automatic washing machine, energy conservation, environmental protection, water saving. So it becomes the object of the most popular.
According to the principle of the working state of the fully automatic washing machine control, we use PLC programmable controller to realize the automatic control of the full-automatic washing machine. Provide better convenience for people's life. The design, the use of the characteristics of the Siemens S7-200 series PLC, for the design of control system, finally to realize the automatic washing machine.
Key words: PLC automatic washing machine
