基于51单片机的汽车智能雨刮器控制系统设计

AbstractThe design of the intelligent wiper takes STC89C52 as the core,andrealizes the intelligent wiper with the single-chip microcomputer as thecontrol system.The focus is on the design of circuit structure principles andcode programming.It includes project overview,program demonstration,intelligent wiper hardware and software design,system debugging and otherparts.This design takes the single chip microcomputer as the controlcore.Based on the method of block mode,the hardware analyzes the circuitdesign of the entire system,and gives the overall structure of the system,theminimum system of the single-chip microcomputer,the drive circuit of thestepper motor,the key circuit,and the display circuit.LCD1602,sensorcircuit and power supply circuit.In the process of software implementation,the block method is also used.The software design part includes intelligentwiper program design ideas and intelligent wiper function analysis.Thestructure and function of the stepper motor,buttons,LCD1602 display andrainfall sensor circuit are designed and implemented,and the logic structureof the main program is mainly written.The software part uses C language toanalyze the rainfall value and set value to complete the automatic start andstop of the wiper and speed control.The design basically achieves theintended purpose and has strong practical value.Keywords:Intelligent wiper,automatic control,MCU,STC89C52,motor drive,LCD1602
