The invention discloses a vehicle-mounted traffic information prompting guideboard system based on a vehicle-road cooperation scene, which comprises a guideboard lamp panel, a power supply module, a guideboard control card, an association unit, a roadside module, a vehicle-mounted module and an original vehicle service module; the power supply module is used for supplying power to the guideboard lamp panel and the guideboard control card; the guideboard control card controls the display of the guideboard lamp panel through a 75/08 interface; the roadside module is used for acquiring traffic signal lamp information on a roadside and communicating with a vehicle; the vehicle-mounted module is a vehicle-mounted MEC in a bus and communicates with the guideboard through a CAN bus. The original bus service module is a vehicle-mounted dispatching host of bus service, and shares a CAN bus with the guideboard and the vehicle-mounted MEC. By adopting the CAN communication mode, the problem of data conflict is solved, the traffic light information is timely and effectively displayed, so that the application of the vehicle-road cooperation technology and the reliable communication technology in the public field is promoted, and the vehicle-road cooperation system is constructed.

    本发明公开了一种基于车路协同场景的车载交通信息提示路牌系统,包括路牌灯板、电源模块、路牌控制卡,关联单元有路侧模块、车载模块、原车业务模块,电源模块用于为路牌灯板和路牌控制卡供电;路牌控制卡通过75/08接口控制所述路牌灯板的显示;路侧模块为在道路侧获取交通信号灯信息并与车辆通讯;车载模块为在公交车辆内部的车载MEC,与路牌通过CAN总线通讯;原车业务模块为公交业务的车载调度主机,与路牌和车载MEC共用一条CAN总线。本发明通过采用CAN通讯方式,解决数据冲突问题,及时有效显示红绿灯信息,推动了车路协同技术和可靠通讯技术在公共领域的应用,从而构建车路协同体系。
