摘　　要：采用达芬奇平台的TMS320DM355芯片为抓拍系统的主控芯片,设计了一种闯红灯违章车辆图像抓拍系统。该系统采用基于地感线圈的车辆检测模块采集车辆行驶状态信息,根据交通信号控制机的红灯信号检测红灯的亮、灭状态信息,抓拍相机实时抓拍违章车辆图像,最后将违章车辆图像存储在SD卡中或通过网络传输至交通管理中心。This paper puts forward a design solution used in the traffic violation snapping system based on DaVinci TMS320DM355 as the main control chip of the system.Vehicle detection module based on induction loop is used to acquire the traffic information.And the red light detection module is used to acquire the on/off state of red traffic lights according to the red light signal of traffic signal controller.The snapping camera snaps the vehicle violation scene in time and the pictures will be stored in the SD card or transferred to the Traffic Management Center if the Internet is accessible.
