The invention discloses an early warning device, an early warning method and an early warning system for preventing a secondary traffic accident. The early warning device comprises: an image collector for collecting road condition images; a processor which is used for judging road conditions and is electrically connected with the image collector; a light module which is used for warning and is electrically connected with the processor; and a receiving and transmitting module which is used for receiving and transmitting wireless information and is electrically connected with the processor. The early warning method comprises the following steps: arranging a plurality of early warning devices at intervals along the roadside; collecting a road condition image; analyzing and judging whether the current road condition is suitable for passing or careful passing; based on the careful passing state, enabling the light module to emit a red and yellow synchronous flickering light warning signal; sending warning information to the N early warning devices which are close to each other in the vehicle coming direction; and enabling each light module of the N early warning devices to emit red and yellow synchronous flickering light warning signals. The method has the advantages of being more effective in warning and more remarkable in effect.

    本发明公开了一种预防二次交通事故的预警装置、预警方法和预警系统,预警装置包括:用于采集路况影像的影像采集器;用于判断路况的处理器,所述处理器与所述影像采集器电连接;用于示警的灯光模块,所述灯光模块与所述处理器电连接;用于接收和发射无线信息的收发模块,所述收发模块与所述处理器电连接。预警方法包括:沿路侧间隔设置多个预警装置;采集路况影像;分析、判断当前路况是适于通行或谨慎通行状态;基于谨慎通行状态,灯光模块发出红黄双色同步闪烁灯光示警信号;并向来车方向的距离近的N个预警装置发送示警信息;N个预警装置的各灯光模块均发出红黄双色同步闪烁灯光示警信号。具有示警更有效、效果更显著的优点。
