The invention discloses a night accident early warning system and method for an extra-large bridge highway based on vehicle-road cooperation, and the system is characterized in that an external field recognition and early warning integrated module is disposed at an external field bridge, and comprises an event recognition device which is used for collecting the vehicle driving state data of a bridge region; the edge computing device obtains vehicle driving state data, analyzes the data and identifies an occurring event; the edge computing device is connected with the holder device, sends instructions to the holder device and the projection device connected with the holder device, and controls the horizontal angle and the pitch angle of the holder device and the projection image and the projection power of the projection device, and the communication device is used for realizing system communication; and the central control module is used for controlling and managing the external field identification and early warning integrated module. According to the scheme of the invention, traffic accidents can be automatically identified under the condition of poor visibility at night and the like, system linkage is carried out, early warning is carried out near an accident point, and the probability of secondary accidents of rear vehicles is reduced.

    本发明公开了一种基于车路协同的特大桥梁高速公路夜间事故预警系统和方法,其中的外场识别预警一体模块设置在外场桥梁,包括事件识别装置用于采集桥梁区域的车辆行驶状态数据;边缘计算装置获取车辆行驶状态数据,并对数据进行分析,识别发生的事件;边缘计算装置与云台装置连接,并向云台装置和与云台装置连接的投影装置发送指令,控制云台装置水平和俯仰角,以及投影装置的投影图像和投影功率,通信装置用于实现系统通信;中心控制模块用于对外场识别预警一体模块进行控制和管理。本发明的方案可在夜间等能见度不好的情况自动识别交通事故,并进行系统联动,在事故点附近进行预警,降低后方车辆发生二次事故的概率。
