The Application of PLC In Entire Automatic Washer Control System
Abstract: With the social economy development and the improvement of technology and science , the family electrical appliance full-automation becomes the inevitable development tendency. Full- automation washer production simplifies people's life tremendously. The washer is the only domestic electrical appliance which does not carry the price fights policy in the family electrical appliance industry .With several years steady development, the domestically produced washer regardless of in quality or in function is all along with the world leading level . This paper studies how the PLC controls full-automation washer,analyses and discusses software design and hardware design , has realized the full- automatiion washer normal operation and compulsory stops the function. Key word: PLC;entire automatic washer;control [资料来源:www.doc163.com]
2.2 设备控制要求
全自动洗衣机控制要求是能实现“正常运行”和“强制停止”两种控制要求。
正常运行
2.2.1 “正常运行”方式具体控制要求
按下启动按扭,开始进水直到水满(即水位达到高水位)时停止进水开始洗涤正转;
洗涤时,正转30秒,停两秒,然后反转30秒,停2秒;
如此循环5次,总共320秒开始排水;
水位下降到低水位时开始脱水并继续排水,脱水30秒;
开始清洗,重复前面步骤,清洗两遍;
清洗完成,报警3秒并自动停机。
强制停止
2.2.2 “强制停止”方式具体控制要求
若按下排水按扭可以实现手动排水;
若按下停车按扭,可实现手动停止进水,排水 脱水及报警
