Design of reversing ultrasonic ranging system based on single-chip microcomputer
In order to achieve precise ranging and improve driving safety,the hardware circuit and software program of an ultrasonic ranging system was designed with a 51 microcontroller as the core,joint simulation with Proteus was conducted,and a product prototype was produced according to the schematic diagram.The test results showed that the hardware circuit of the ultrasonic ranging system was simple and reasonable,with excellent performance,stable operation,fast ranging,and could automatically trigger the alarm when it was close to the obstacle.In terms of measurement accuracy,it basically met the ranging requirements when the car was reversing.
