基于C51防汽车追尾报警系统的研究

随着社会经济的发展交通拥挤状况日趋严重,在汽车高速行驶过程中由于汽车故障引起的撞车事件屡屡发生,针对这种情况,设计一种响应快,可靠性高且较为经济的汽车防撞预警系统势在必行。汽车防撞系统是一种可向司机预先发出警告信号的报警装置。该系统启动后可在自身发生故障后向邻近汽车报警及可接收邻近汽车的报警信号,以便司机采取相应的措施应付险情。本设计主要是通过检测安装在汽车各个关键部位的传感器传来的信号来判断汽车的状况,如有问题则通过基于VD5026和VD5027芯片设计的发射和接收电路来通知或获取邻近汽车的险情。报警采用基于ISD2560的语音报警电路,主控机采用89C51。该系统设计经济实惠,对汽车行驶的安全提供了保障。

Study on the Warning System of Avoiding Automobile Collision Based on C51

The traffic jam more and more serious along with social develop.The automobile collision occurred frequently when the automobiles advance at high speed on the expressway.It is very impossible to design the responded quickly、feasibility highly and ecomically system of avoiding automobile collision.The system is a warning installation.It give the alerting singal for the driver when thr automobile has broken down.The driver could known and get everything beforehand.The automobile installed some sensor on the key position.The system checked the automobile with the sensor singal.If a automobile stoped by the breakeddown,the system would notify or obtain the dangerous for the nearly automobile through the transmit and receive circuit based on VD5026 and VD5027.The pronunciation warner circuit be designed based on ISD25027.The system controled by the single chip microcomputer 89C51.The design are economical and provide safeguard for the driving automobile.
