摘 要:为了减少交通事故的发生,设计了一个用于汽车主动防撞报警以及刹车系统。该系统以单片机为控制核心,采用红外线发射和接收电路以及报警电路,实现了对汽车是否发生碰撞的预算及报警。在不同汽车行驶情况下,通过红外线装置测得的数据交由单片机运算可得出汽车之间的间距。当汽车间距超过限定值未到自动刹车距离时,单片机给报警电路发出信号,由报警电路执行报警;当汽车间距小于自动刹车间距时,触发自动刹车系统,进行刹车。该系统具有检测精度高,运行可靠,操作简便等特点。40648 毕业论文关键词:单片机;红外线;防撞;测距
Design of Infrared Anti-collision System for Car
Abstract: In order to reduce the occurrence of traffic accidents, one of automotive active collision avoidance warning and braking system design. This system takes the MCU as the control core, using the infrared transmitting and receiving circuit, sensor circuit, the realization of the if the car collision budget and alarm. Different vehicle driving conditions, through the infrared device data measured by SCM operation can be drawn from the distance between the cars. When the car spacing exceeds the limit value is not to the automatic braking distance, sends a signal to the alarm circuit by the micro-controller, alarm circuit implementation of the alarm; when the vehicle spacing less than the automatic braking distance,triggering automatic braking system, brake. The system has high detection precision, reliable running, easy operation etc..
