The invention discloses an expressway secondary accident active early warning system and method based on video detection, and the system comprises a front-end camera module which is disposed at an accident-prone road segment and carries out the real-time monitoring; a central processing control module which is used for receiving and processing the monitoring information of the front-end camera module, judging whether a vehicle has a fault or not and generating corresponding instruction information according to the fault; an alarm module which is used for receiving the instruction information of the central processing control module and giving an alarm in a multi-step alarm mode according to the instruction information, and the alarm module is arranged on an accident-prone road section; anda data transmission module which is used for information transmission among the modules. The system has the advantages that the front-end camera module, the central processing control module, the alarm module and the like are combined, the defects of inaccurate positioning, discontinuity and the like of an existing alarm mode are overcome, a tripod and other warning articles placed by field personnel are omitted, the safety of the field personnel is guaranteed, and the purpose of preventing secondary accidents of expressways is achieved.
本发明公开了一种基于视频检测的高速公路二次事故主动预警系统及其方法,该系统包含:前端摄像模块,其设置于事故高发路段并进行实时监测;中心处理控制模块,其接收并处理前端摄像模块的监测信息,并判断是否有车辆发生故障,据以生成相应的指令信息;报警模块,其接收中心处理控制模块的指令信息并根据指令信息采用多级阶梯式报警方式报警,报警模块设置于事故高发路段上;数据传输模块,用于各模块之间的信息传输。其优点是:该系统将前端摄像模块、中心处理控制模块、报警模块等相结合,克服了现有报警方式的定位不准确、不连续等缺陷,该系统省去了现场人员放置三脚架等示警物品,保障了现场人员的安全,达到预防高速公路二次事故的目的。
