超声波倒车雷达系统的设计 [摘要] 大家都知道现在的交通压力很大，私家车出门遇到堵车是时有发生的常事，并且在倒车时是会有倒车盲区的，所以设计研发一款倒车防撞的预警系统是很重要的。本文就是基于超声波测距并且预警的防撞报警系统。工作时，超声波传感器发出脉冲信号，经障碍物反射后由超声波接收装置接收并送至单片机处理，可实现倒车时障碍物距离的实时监测并通过LED显示和声光报警提示驾驶员。本课程设计是以AT89C51单片机为基础的超声波倒车雷达系统，包括超声波发射和接收部分、单片机处理部分、LED显示部分和声光报警部分等。 [关键词] 倒车雷达；单片机控制；超声波测距；声光报警 Design of ultrasonic parking sensor systems [Abstract] Now everyone knows the traffic pressure is very big, private cars go out meet traffic jams are common have occurred, and is there will be a reverse blind area in reverse, so the design development of a reverse collision warning system is very important.This article is based on the ultrasonic ranging and collision avoidance warning alarm system.Work, ultrasonic sensor signal pulse, the obstruction after reflection by ultrasonic receiver receives and sent to the microcomputer processing, which can realize obstacle distance while backing of real-time monitoring and through the LED display and sound and light alarm prompt drivers.This course design is based on AT89C51 single chip ultrasonic reversing radar system, including ultrasonic transmitting and receiving, a single chip, LED display parts and sound and light alarm, and so on.
