| Abstract: | The agricultural working environment is complicated,so it is very important to monitor the speed of agricultural motor in real time.A motor speed monitoring system is designed,which is mainly composed of photoelectric switch sensor,trigger disk,OLED and STM32 microcontroller.Through the function of timer interrupt and external interrupt of the microcontroller,the motor speed can be monitored in real time,and the speed data can be visualized through IIC communication technology.The system has strong anti-interference ability,high precision and practicability,and is suitable for harsh agricultural working environment.Meanwhile,it provides design basis for other rotational speed monitoring schemes. |
