Design and Simulation of washing machine controller based on 80C51 microcontroller

Abstract: The system is based on 80C51 microcontroller washing machine controller design and simulation, SCM applications to people with a lot of convenience。 In this paper, the use of AT89C51 microcontroller as a washing machine controller, it will be as the core, and then match the LCD LCD screen, H bridge, control motors, buzzer and other auxiliary circuit components。 Through the Proteus simulation software, we have to design all the circuits through simulation show。 SCM through the key signal acquisition, adjust each parameter, use the button can make reservations for each stage of the time。 The button is adjusted and the LCD LCD screen is displayed, adjusted and operated in real time during the operation。 The user sets the status of the reservation by operating the button, such as the agreed water inlet time, dehydration time, etc。。 The indicator module is used to indicate the current state of the machine running。 The H bridge circuit controls the positive and negative rotation of the motor, and the buzzer prompts the alarm after the end。 The whole work process starts with one button, one button can be paused, or the machine can continue to run, so as to realize the automatic operation of the washing machine。

Keywords: Washing machine controller；AT89C51 microcontroller；LCD screen； Proteus simulation software。
