Abstract
Full automatic washing machine itself to the people brought great convenience, more and more people accept washing machine instead of hands to create a more comfortable life for themselves, along with the development of the times, it will become a member of the family essential.
In recent years, with the constant renewal of science and technology, MCU development also presents is the rapid change, with high integration density, computing speed fast, small volume, reliable operation and low price and other characteristics in household appliances, intelligent instrument, has been widely used.?The design of ATMTEI microcontroller AT89C51 as the control core, its control object mainly include: key, water valve, drainage valve, motor, LCD, etc..?The overall design of key parts are used to select the full automatic washing machine, the running speed of the motor, start / pause, drive circuit L298 to realize motor, a water inlet valve and a drain valve, the alarm circuit is with a buzzer to send sound to remind the user and malfunction alarm, detection circuit is mainly used to detect the water level, power supply with three terminal voltage regulator integrated 7805 provide + 5V power supply.The wash, rinse and dehydration process all is controlled by the system automatically, with LCD display the working state of the washing machine and the rest of the time.?The program design includes the main program, the external interrupt program, the timer program, the key scan program, and so on, and finally, the function of the design is realized by using proteus.
