    • PROBLEM TO BE SOLVED: To provide a vehicle position display device capable of detecting the position of a railroad vehicle even when any fixed track circuit is not present, and realizing the railroad operation with less dependency on a ground installation. SOLUTION: The coordinates of the global coordinate system of the present vehicle position is measured by utilizing a GPS satellite 6, and a ground installation closest to the starting point side with respect to the vehicle position from a track management information DB1014 and its mileage are obtained based on the measurement of position. Next, the vehicle position and the coordinates of the map coordinate system of the ground installation closest to the starting point side are obtained to read the track vector data R from a track layer 1012a of map information DB1012, and the length Lm along the track 5 between the vehicle position and the ground installation closest to the starting point side is calculated. The real distance Lr is calculated from the scale size of the map, and added to the mileage of the ground installation closest to the starting point side to calculate the distance of the vehicle position. The kind of the signal is displayed by comparing, for example, the calculated mileage difference between vehicles with the safety braking distance, and the operational navigation will be given to a driver.

    • 要解决的问题:提供即使在不存在固定轨道电路的情况下也能够检测铁路车辆的位置的车辆位置显示装置,并且以较少依赖于地面装置的方式实现铁路操作。 解决方案:通过使用GPS卫星6和相对于车辆位置的起始点侧的地面安装轨道管理信息DB1014及其轨道管理信息DB1014来测量当前车辆位置的全局坐标系的坐标 基于位置的测量获得里程。 接下来,获得最接近起始点侧的地面坐标系的车辆位置和坐标系,从地图信息DB1012的轨道层1012a读取轨道矢量数据R,沿轨道5读取长度Lm 计算最靠近起点侧的车辆位置和地面安装之间的距离。 实际距离Lr是根据地图尺度计算出的,并加到最靠近起点侧的地面安装位置的里程,以计算车辆位置的距离。 通过比较例如具有安全制动距离的车辆之间的计算里程差异来显示信号的类型,并且将给予驾驶员的操作导航。 版权所有(C)2006,JPO&NCIPI
