The embodiment of the invention provides a train length calculation method, device and system. The method comprises the following steps: obtaining train head positioning information and train tail positioning information of a train; determining a corresponding train head position point and a corresponding train tail position point in an electronic map according to the train head positioning information and the train tail positioning information, and dividing a target line between the train head position point and the train tail position point in the electronic map into at least one first linesegment; wherein the electronic map records map information of a running line of the train and records a straight rail area and a curve area on the line, and each first line segment corresponds to onestraight rail area or one curve area on the target line; and calculating the real length of each first line segment according to the divided endpoint coordinates of each first line segment, and obtaining the total train length of the train according to the real length of each first line segment. By the adoption of the scheme, the problem that in the prior art, the train length is inaccurate can be solved.

    本申请实施例提供了一种列车车长计算方法、装置及系统,该方法包括:获取列车的车头定位信息和车尾定位信息;根据车头定位信息和车尾定位信息在电子地图中确定出对应的车头位置点和车尾位置点,并将电子地图中车头位置点至车尾位置点之间的目标线路划分为至少一个第一线路段;其中,电子地图记录列车所行驶线路的地图信息以及记录线路上的直轨区域和弯道区域,每一第一线路段对应于目标线路上的一个直轨区域或者一个弯道区域;根据划分出的每一第一线路段的端点坐标计算每一第一线路段的真实长度,根据每一第一线路段的真实长度得到列车的总车长。采用本申请中的方案,能够解决现有技术中存在的列车车长不准确的问题。
