摘要
基于ARM的调制式红外光汽车速度管理系统是以红外光传感器、ARM为核心的新的测速系统,测速时不会被"电子狗"所发现,不仅能识别汽车速度V的大小,还能测出车辆速度超过上限速度(Vmax)的量值+△V或低于下限速度(Vmin)的量值—△V等信息,据该信息驱动取证系统(打印、照相)工作,能有效提高交通管制的力度。该系统由于采用了ARM嵌入式处理器、uclinux操作系统以及触摸屏,不但人机交互性好,而且升级和扩展能力强,工作稳定,具有较大的应用前景。
To prevent the circumstance, a new speed management system with infrared sensor based on ARM has been developed in this paper. It can not only identity the speed, but also show how much it exceeds ( +ΔV ) or lags ( ΔV ) the speed limits. According to the overspeed information, it can drive the sampling system to work (to print or take pictures), and get the effectively traffic control. Designed with ARM uclinux OS and touch display, the system has nice GUI and upgrade ability, which will be widely used in traffic management field.
