| 摘 要： | 为了降低汽车倒车时因＂后视＂不良而引起的刮擦碰撞事故,设计了一款汽车倒车防撞预警系统。该系统以AT89S52单片机为主控单元,采用HC-SR04超声波测距模块实现非接触式测距,在硬件匹配的基础上,进行了电路设计和软件设计,并进行了测试实验,对测距误差进行了分析。本系统探测距离可为2~400 cm,测距精度可达3 mm,能够满足汽车在狭小空间内的倒车预警要求。

| Abstract: | In order to reduce the collision accident as a result of bad rear view when reversing, the anti-collision warning system was designed. The control unit of system is AT89S52 microcontroller,which complements non-contact distance measurement by HC-SR04 ultrasonic distance sensor. On the basis of the hardware to match, the circuit design and software design were carried out. Finally, the test experiment and the ranging error analysis were all made. The system detection range can be2cm~400cm and the measuring accuracy is up to 3 mm. So it is fully possible to meet the design requirements with the car reversial warning system in the narrow space. |
