Description

Technical Field

[0001] The utility model relates to the technical field of train positioning, in particular to a train precise positioning device. Background Art

[0002] Existing train positioning relies on systems such as Beidou or GPS for positioning and navigation. Although existing navigation systems generally have positioning deviations, this is a normal phenomenon because the deviations are generally small and will not affect the normal operation of the train. However, in actual use, multi-track positioning deviations will occur. That is, when the distance between adjacent tracks is close, it is impossible to distinguish which track the vehicle is traveling on, resulting in vehicles traveling on track A being mistakenly positioned on track B or vehicles traveling on track B being mistakenly positioned on track A. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a train precise positioning device, which solves the problem that the existing train positioning error causes excessive deviation and leads to track positioning error.

[0007] The locomotive automatic parking device comprises an automatic parking device MCU, a solenoid valve exhaust brake and a beacon reading device.

[0008] Preferably, the signal machine is electrically connected to the signal wireless transmission device and the section signal light wire respectively.

[0009] Preferably, the automatic parking device MCU is electrically connected to the locomotive signal MCU, the solenoid valve exhaust brake and the beacon reading device wires respectively.
