基于51单片机的汽车预警系统的设计与实现

Design and Implementation of Automobile Warning System Based 51 Single Chip Microcomputer

随着汽车在现代生活中的普及,一些交通安全方面的隐患也随之产生。基于51单片机的汽车预警系统利用超声波测距技术,通过发射器发出的信号到接收器接收的信号之间所需时间来准确计算出两辆车之间的距离,特别适合给各种行车提供预警的作用。另外,该系统采用数码电子管显示屏可使驾驶者直观的看到目前车间距离,同时,采用蜂鸣器报警来预警驾驶员注意安全车距。该系统的实时监测,对驾驶员的安全出行提供了一定的保障。

With the popularity of cars in the modem life, some of the hidden dangers of traffic safety also is produced. The automobile warning system, which is based 51 single chip microcomputer, uses ultrasonic distance measurement technology to accurately calculate the distance between two cars, its distance is calculated through the time required the signal from the transmitter to the receiver. The system provides early warning for the various driving. In addition, the digital tube of the system displays the current distance between the driving, which the driver can see intuitively. At the same time, the buzzer alarm is used to alert the driver to pay attention to the safety of vehicle distance. The real-time monitoring of the system, provides a certain guarantee for the driver＇ s safety travel.
