ABSTRACT
This design mainly introdcts the washing machine control circuit whichis based on the digital integrated circuit technology , using the single chip microcomputer 8051 as the core, with combining software with hardware . The washing machine control circuit realizes the function of washing machine water, washing, rinse, dehydration and drainage.
Besides we design the indicator light which can indicate the working state of the washing machine.Based on single chip microcomputer,the automatic washing machine control system has the property of high precision, strong function, good economy and so on. No matter in the aspect of increasing the quality and quantity of products, saving energy or improving working conditions, the automatic washing machine control system has clinking superiorities.
Key words:The washing machine; 8051MCU; Integrated circuit ;Control system
