The invention provides an accident early warning method, device and system and electronic equipment, and relates to the technical field of traffic safety, and the accident early warning method comprises the steps: sending an accident early warning to vehicle-mounted equipment in a target distance range under the condition of determining a target flow direction type of a fog flow direction in a target region; the target flow direction type is the type of fog flow direction when a vehicle accident occurs in the target area; the target distance range is a preset distance range in the direction opposite to the driving direction of the vehicle. According to the invention, based on the characteristic that the type of the flow direction of the fog flow during the normal passing of the vehicle is different from the type of the flow direction of the fog flow during the accident of the vehicle, when the type of the fog flow is the type of the fog flow during the accident of the vehicle, the accident can be predicted, and the accident early warning is sent to the vehicle-mounted equipment within the target distance range. Therefore, a driver can perform corresponding operation on the vehicle in advance based on accident early warning.

    本发明提供一种事故预警方法、装置、系统及电子设备,涉及交通安全技术领域,其中,事故预警方法包括在确定目标区域内雾气流流向的目标流向类型的情况下,向目标距离范围内的车载设备发送事故预警;所述目标流向类型为预测所述目标区域内车辆发生事故时雾气流流向的类型;所述目标距离范围为与所述车辆的行驶方向的相反方向上的预设距离范围。本发明基于车辆正常通行的雾气流流向的类型与车辆发生事故时雾气流流向的类型不同这一特性,在雾气流类型为车辆发生事故时雾气流的类型时,可以预测发生事故,并向目标距离范围内的车载设备发送事故预警,使得驾驶人员基于事故预警可以提前对车辆做相应的操作。
