摘 要:在汽车倒车时,车主可以通过终端显示器,清晰地看到汽车尾部和侧部与附近物体之间的距离,而一旦两者之间的距离小于系统预设的值时,系统就会发出警报,提示司机及时进行处理,避免出现碰撞剐蹭。可见,敏感性强、性能良好、探测范围广的测距报警系统,在日常行车中具有非常重要的应用价值。本文在简要阐述超声波测距运行机制与原理的前提下,对基于单片机的超声波测距报警系统进行了整体设计,并从硬件系统和软件系统两方面入手展开了详细论述。

Abstract:When reversing a car,the owner can clearly see the distance between the rear and side of the car and the nearby objects through the terminal display. Once the distance between the two is less than the preset value of the system,an alarm will beissued to prompt the driver to deal with it in time to avoid collision. It can be seen that the ranging alarm system with strong sensitivity,good performance and wide detection range has very important application value in daily driving. On the premise of briefly explaining the operation mechanism and principle of ultrasonic ranging,the overall design of ultrasonic ranging alarm system based on single-chip computer is carried out,and the hardware system and software system are discussed in detail.
Keywords:single chip computer;ultrasonic ranging;software system
