本文介绍了采用可编程控制器()作为核心控制部件的全自动洗衣机的控制系统。通过介绍洗衣机的结构,对全自动洗衣机的控制系统进行了分析,在此基础上提出了基于控制的全自动洗衣机控制方案,并对方案进行了论证。根据洗衣机的工作原理,设计了流程及程序,对按钮、继电器、开关、变频器等其它一些输入/输出点进行控制,实现了洗衣机洗衣过程的自动化。由于洗涤,排水,脱水的时间均由PLC内计数器控制,所以只要改变计数器参数就可以改变时间。具有智能化程度高、安全可靠、方便、灵活等特点。br /
可编程控制器(PLC)是以计算机技术为核心的通用自动化控制装置,它的功能性强,可靠性高,编程简单,使用方便,体积小巧,近年来在工业生产中得到广泛的应用,被誉为当代工业自动化主要支柱之一。br /
在现代的社会,全自动洗衣机进入各个家庭,本文介绍了PLC用于全自动洗衣机的控制系统,其可改进现有技术的不足,简化结构,有利于降低成本和提高可靠性。 br /

Abstractbr /
This article used programmable controller PLC to realize the washer completely automatic control, explained the PLC control principle method, the characteristic and controlled the washer the characteristic. The article during introduction washer structure, carries on the analysis to the completely automatic washer control system, proposed in this foundation based on the PLC completely automatic washer control plan, and has carried on the proof to the plan, has carried on the design according to the washer principle of work to the procedure and the flow, has the intellectualized degree high, safe reliable and so on the characteristics. To the button, the relay, the switch, the frequency changer and so on other some I/O spot carries on the control, realized the washer to wash clothes the process automation. Because spreads every time lavation, draining water, dehydrated time by PLC in counter control, so long as therefore the change counter parameter may change the time. span class=Thc990/span br /
