| 摘 要： | 针对汽车倒车时的"后视"不良引起的倒车事故,介绍了一种基于超声波的倒车雷达预警系统.该系统在汽车挂倒挡时开始工作,通过超声波传感器发送超声波检测障碍物信息,经微处理器处理成测距信息,并进行显示,当距离小到设定的安全范围时,自动启动语音报警,该系统安装简单,抗震能力强,测距准确且工作稳定可靠.该文给出了系统各部分的硬件及软件实现,并分析了误差产生的原因.

| Abstract: | Aiming at the car accident caused by the bad back-sight,a reversing radar alarming system based on the ultrasonic wave sensor has been proposed in this paper.This system begins to work during the back-draft time,it uses the ultrasonic wave transmitted by an ultrasonic sensor to detect the obstacle information.The ultrasonic wave information is processed to the distances information and displayed by the microprocessor.When the distance is smaller than the determined safety range,the system will start to aler... |
