基于51单片机的三路超声波倒车雷达系统 系统主控使用的是STC12C5A60S2单片机,使用了超声波HC-SR04模块、语音播报模块 系统的主要功能如下所示: (1)显示功能 系统使用OLED显示模块,将三个超声波模块采集的距离在屏幕上进行显示。 (2)蜂鸣器频率变化功能 随着超声波模块检测的距离不同,蜂鸣器进行不同频率的鸣叫,距离以检测的三组距离里面最短的距离为基准。 (3)语音播报功能 系统会对检测的三组距离值里面最短的距离值进行播报,以提醒驾驶者规避障碍物。 (4)倒车与刹车功能 当检测的距离处于中距离和远距离时,电机正常转正,当检测的距离处于近距离了,系统会对电机进行止动,从而实现刹车功能。
