电动自行车追尾防撞报警系统的设计

目前,电动自行车的安全问题已引起各界关注。本文基于超声波测距技术,以MCS-51系列单片机为控制核心,采用语音报警电路,对电动自行车的追尾防撞进行语音报警,最终实现了电动自行车追尾防撞报警系统。为了保证一定的准确度,系统采用DS18B20温度传感器测量环境温度,对超声波测距公式不断进行修正。

At present,the security problems of electric bicycles are followed with interest by all circles.Based on the ultrasonic distance measuring technical,this paper takes the single chip microcomputer of MCS-51 series as control core;and the voice warning circuit is used to realize the rear-end collision of electric bicycles.Finally,the warning system of avoiding the rear-end collision between electric bicycles is implemented.In order to guarantee certain accuracy,the system measures the environmental temperature by the DS18B20temperature sensor,and modifies continuously the formula of the ultrasonic distance measurement.
