基于51单片机的全自动洗衣机控制器（Controller of full automatic washing machine based on 51 single chip microcomputer） Based on 51 single-chip automatic washing machine controller (1) based on 51 single-chip automatic washing machine controller (1), based on 51 single-chip automatic washing machine controller (1) hidden Information technology 2005NO.25 technology information SCIENCETECHNOLOGYINFORMATION industrial technology based on 51 single-chip automatic washing machine controller of Lin Yi Zhou (Fujian Polytechnic of Information Technology Fujian Fuzhou 350019) Abstract: This paper describes the function, hardware, software, and other aspects of a work process with AT89C2051 as the control system of washing machine. The system is simple in hardware and low in cost, but its function is as complete as that of an ordinary washing machine due to the multiplexing technology used in many places. With immersion function is a major feature of the system. Keywords: water immersion washing drainage dehydration suspended a chip microcomputer AT89C2051, AT89C2051 microcontroller is ATMEL company AT89 series of economic in low-priced products, instruction compatible MCS 51 instruction set, it contains the 2KB Flash memory programming and 128 bytes of RAM, 15 programmable I / O lead and 5 interrupt sources. In the case that the I / O line is not needed, the core chip can be greatly simplified and the cost is lower by using it as the core control chip. Rest drive (drive 5 seconds, pause for 2 seconds) so as to save energy. During the period of inertia, the bucket is kept rotating at high speed by inertia force. 7. pause function. When pressing the pause button / start button, the washing machine must stop working, and then press the button, the washing machine can continue to work according to the original mode of work. 8. sound and light display function. The washing machine selection of various working methods and all kinds of working conditions are sound, light tips or display. Two 、 funct
