基于单片机的倒车防撞系统

Reversing anti-collision system based on single chip microcomputer

基于单片机的倒车防撞系统运用了超声波不易受干扰、经济实惠的特点。该系统主要由LCD1602显示模块、语音播报模块、超声波测距模块、单片机模块、声光报警模块、按键模块和电源电路组成。在遇到障碍物时,显示模块会分左右前三个数据分别显示,语音播报系统每隔三秒会警报一次。此设计比单个的超声波测距模块能检测的范围更广,一般的测距雷达只能检测正后方的障碍物,而此设计还能检测到左右两侧的障碍物,解决了视角盲区的问题。

Reversing anti-collision system based on single chip microcomputer uses the characteristics that ultrasonic is not easy to be disturbed and economical,and combines single chip microcomputer.The system is mainly composed of LCD1602 display module,voice broadcast module,three-way hc-sr04 ultrasonic ranging module,single chip microcomputer minimum system and power circuit.It has a wider range than a single hc-sro4 ranging alarm.When encountering obstacles,the display module will display the first three data respectively,and the voice broadcasting system will alarm every three seconds.This design can detect a wide range than a single ultrasonic ranging module,the general ranging radar can only detect the rear obstacles,and this design can also detect the left and right sides of the obstacles,to solve the problem of blind angle.
