Abstract
Washing machine is the People's Daily life common kind of home
appliance, life has become a indispensable household electrical
appliances. In the industrial production is also widely used. But the
traditional relay-based control, cannot have satisfied people to the
requirements of the automation degree of the washing machine. Along
with the development of the single chip microcomputer by using single
chip processor to as a controller, and can better control washing machines,
and to control the way agile diversity, control mode according to different
situation the application can be different. With a small volume and
microcontroller programming flexibility and produce DuoZhong control
function, and can meet the design requirements. The system USES
AT89C51 single chip microcomputer as control system, the design
purpose mainly to familiar with single-chip microcomputer system the
basic method to design and realize the basic function of the washing
machine. The system control panel composed mainly by button switches,
key choice washing machine work mode, and may, according to needs to
adjust the washing time length. LED LCD display of the washing
machine is working mode and washing time. The washing machine of the
whole circuit module includes key matrix, liquid crystal display, motor
and power circuit. Control program design including timing interrupt
service procedure, time setting process, and outside the interrupt service
