摘要
此系统主要是由单片机以及其他外部电路构成了硬件部分,程序组成了软件部分。通过超声波的发射和接收,将信号传到到单片机。经过信号数据收集分析、计算和处理,传输至显示器。如果测量距离小于设定值,则及时通过报警模块发出报警信号。经过测试,该系统误差小,灵敏度高,能够实现相应功能,可以有效降低倒车事故的发生率,提高其安全性能。
This system is mainly composed of a single-chip microcomputer and other external circuits,and the program forms the software part.The signal is transmitted to the microcontroller by the transmission and reception of ultrasonic waves.After signal data collection analysis,calculation and processing,transmission to the display.If the measured distance is less than the set value,an alarm signal is sent through the alarm module in time.After testing,the system has small error,high sensitivity,and can achieve corresponding functions,which can effectively reduce the incidence of reversing accidents and improve its safety performance.
