Abstract :This engineering design is to regard AT89C2051 as the key component , because there are few pins of AT89C2051, the memory is not big in capacity, so, the function of the washing machines controlled has certain restriction , but, because the basic function of the washing machine is to the washing of the clothes, so, the key lies in carrying on the control of the laundry procedure. Proceed from this angle, analyse , the main function of the automatic washing machine designed has the following seven items to the function of the washing machine : Have strong , weak washing functions; Four laundry working routine, already standardization program , economic procedure, procedure drain off water procedure enter , drainage system trouble diagnose the function automatically alone; Safe protection while dehydrating and defending the vibration function; Drive way of the
intermittence ; Suspend the function; The sound only shows the function.
Key word: AT89C2051, full-automatic washing machine, engineering design , control circuit
