摘要

它被制成了一种装置，可以帮助司机在停车时避免事故。司机知道车辆的范围和后面的任何物体。此外，通知装置应有助于机器自动停机。该装置采用超声波作为测距仪，单片机AT89S52进行计算，并将计算结果显示在液晶屏上。该计算也用于管理蜂鸣器和继电器作为执行器。在本实验中，用玩具车对装置进行了反向行驶的模拟。在任何范围内，蜂鸣器都会主动发出信号，如果汽车仍在行驶，蜂鸣器会继续切断汽车的电流。结果表明，该装置性能良好，可计算出3 cm的最小距离和330 cm的最大距离。蜂鸣器的声音在200 cm ~ 3 cm的谨慎和临界范围内是活跃的，在20 cm以下的临界范围内车辆的机器发生故障。

Prototype of automatic parking aid based on microcontroller AT89S52

It has been made a device that could help driver from accidents when parking a car. The driver knows the range of the vehicle and any object behind. Moreover, the informing device should help to break the machine down automatically. This device used ultrasound as range finder, microcontroller AT89S52 as processes calculation and displays result in LCD screen. This calculation is also used for managing buzzer and relay as the actuator. In this experiment, device has been simulated by toy car which run reversely to object behind. On any ranges, buzzer sound would sign actively, and it continued to break the electric current of the vehicle if it was still running. The result showed that the device could perform appropriately and could calculate 3 cm of minimum range and 330 cm of maximum range to object. The sound of buzzer was active in caution and critical range, that is 200 cm to 3 cm, and the machine of vehicle broke down in a critical range under 20 cm.
