ABSTRACT

This article introduced in detail the domestic washing machine control system's development and present situation, in the development faces question. Simultaneously also in exhaustive introduction this design most important building block monolithic integrated circuit's concept, principle of work and equipment gross structure. Acconding to the washing machine control requirements,a control system with the AT89C51 microcontroller as the core about washing machines were described in the folloeing three aspects of functional requirements,hardware design ,software design . Based on the AT89C51 microcontroller laundry control system, control panel from the button. Indicator components. button to choose washing machines work, with a key indicator. washing machines, the overall circuit module including keyboard matrix, lamp, motor control and power supply circuit. control procedures designed timer interrupt service procedures, external interrupt service procedures and the main program.
