The invention provides an electronic map segmentation downloading method and device, and the method comprises the steps: calculating the running distance of a train decelerated from the maximum running speed to 0 according to the maximum running speed and braking deceleration of a line where the train is located; comparing the product of the distance multiplied by a preset coefficient with the length of a previous interlocking section of the train; wherein the preset coefficient is greater than or equal to 1; and determining the total length of an interlocking section corresponding to the electronic map downloaded to the train according to a comparison result, and downloading the electronic map to the train according to the determined total length of the interlocking section. According to the method, the electronic map with the appropriate track length is downloaded, and it is guaranteed that the train does not decelerate or degrade.

    本发明提供一种电子地图分割下载方法及装置,该方法包括:根据列车所在线路的最大运行速度和制动减速度,计算所述列车从所述最大运行速度减速到0所运行的距离;将所述距离乘以预设系数的乘积与所述列车的前面一个联锁区段的长度进行比较;其中,所述预设系数大于或等于1;根据比较结果确定下载到所述列车的电子地图对应的联锁区段的总长度,根据确定的所述联锁区段的总长度,将所述电子地图下载到所述列车。本实施实现下载合适轨道长度的电子地图,保证列车不降速不降级。
