Abstract汽车雨刷
The design of the intelligent wiper takes STC89C52 as the core, and realizes the intelligent wiper with the single-chip microcomputer as the control system. The focus is on the design of circuit structure principles and code programming. It includes project overview, program demonstration, intelligent wiper hardware and software design, system debugging and other parts. This design takes the single chip microcomputer as the control core.Based on the method of block mode, the hardware analyzes the circuit design of the entire system, and gives the overall structure of the system, the minimum system of the single-chip microcomputer, the drive circuit of the stepper motor, the key circuit, and the display circuit. LCD1602, sensor circuit and power supply circuit.In the process of software implementation, the block method is also used. The software design part includes intelligent wiper program design ideas and intelligent wiper function analysis. The structure and function of the stepper motor, buttons, LCD1602 display and rainfall sensor circuit are designed and implemented, and the logic structure of the main program is mainly written. The software part uses C language to analyze the rainfall value and set value to complete t
he automatic start and stop of the wiper and speed control. The design basically achieves the intended purpose and has strong practical value.
