The invention relates to an unmanned crossing remote early warning method, which comprises the following steps of: calculating a distance L between a vehicle and a nearest crossing camera in a forward direction according to a real-time position of the vehicle and a preset camera configuration file, and turning to a next step when the distance L between the vehicle and the crossing camera is smaller than a set value Lth; the central server activates the crossing camera according to the identification information, obtains a video of the crossing camera and sends the video to the vehicle-mounted host; the vehicle-mounted host displays a video and recognizes a video picture, and when a static obstacle exists or the collision probability with a moving target is larger than a threshold value, collision early warning is given out; and turning off the crossing camera according to the identification information after the vehicle passes through the crossing. Compared with the prior art, the unmanned crossing remote lookout and early warning system provides unmanned crossing remote lookout and early warning functions for locomotive drivers, can obtain video streams of specified crossings at any position by utilizing the central server, is convenient for the locomotive drivers to know the crossing traffic conditions, gives out early warning when collision is possible, and improves the train passing safety.

    本发明涉及一种无人道口远程预警方法,包括以下步骤:根据车辆实时位置和预设置的摄像机配置文件计算车辆与前行方向上最近的道口摄像机的距离L,当车辆与道口摄像机的距离L小于设定值Lth时转下一步;中心服务器根据标识信息激活道口摄像机,获取道口摄像机的视频并发送至车载主机;车载主机显示视频并对视频画面进行识别,当存在静止障碍物或与移动目标的碰撞概率大于阈值时发出碰撞预警;在车辆驶过道口后根据标识信息关闭道口摄像机。与现有技术相比,本发明为机车司机提供无人道口远程瞭望及预警功能,利用中心服务器可以在任何位置获取指定路口的视频流,方便机车驾驶员了解道口交通状况,并在有碰撞可能时发出预警,提高列车通过安全性。
