Entire automatic washer control system design
Abstract: Along with the social economy development and the science and technology level enhancement, the family electric appliance entire automation becomes the inevitable development tendency. Entire automatic washer production enormous convenience people's life. The washer is the domestic electrical appliances industry does not only hit the profession which the price fights, passes through several year steady development, the domestically produced washer regardless of in quality or in function all with world leading horizontal synchronization. Looks over the washer market, the highly effective energy conservation, the province water, the province electricity, the environmental protection washer continuously occupy the dominant position in the market. How does this paper study controls the entire automatic washer using PLC, to question and so on software design, hardware design has carried on the analysis and the discussion, has realized the entire automatic washer normal operation and compulsory stops the function.
Key word: PLC entire automatic washer control
