Design of Washing Machine Control System Based on Single Chip Microcomputer

Abstract In the age of rapid development of digital technology, the field of intelligent control less often against a background of digital technology. many engaged in the electronics industry because of the SCM superior price in choice control center is often favored single chip, it is suitable for real-time control and in industrial control and intelligent instrument, intelligent interface plays a important role. In this paper, the design of washing machine based on single-chip microcomputer control system, by the main control system provides a 5V DC voltage as a voltage source, using the AT89C52 chip, hardware consists of LED lights, digital tube circuit, a buzzer circuit, motor drive circuit, / drainage circuit, keyboard circuit composed of the design of six parts. Triode 8050 as switch control buzzer, motor drive DC motor control L298D, digital tube display mode of the countdown, with three keyboard to as input mode selection, software with C programming language to complete the overall function. Through the design of hardware and software, the control of washing, rinsing and drainage mode of washing machine is realized.   

This paper has 20 figures, 1 table, 20 references.
