Abstract

The embodiment of the invention provides a train positioning method and system. The method comprises the steps that main and standby network MR information reported by a train-mounted TAU is acquiredaccording to a preset period; the main and standby network MR information and the base station Cell ID information are sent to an OMC system; and the OMC system compares the main and standby network MR information and the base station Cell ID information with reference data, and obtains the actual physical position of a train according to a preset algorithm. According to the embodiment of the invention, the method achieves the train position positioning through the main and standby dual-network MR information reported based on the vehicle-mounted TAU, can replace a conventional train positioning system, avoids the repeated construction, and saves the equipment investment cost.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train positioning method and system. Background technique [0002] In the rail transit scenario, due to the fast running speed of trains and small scheduling intervals, in order to ensure driving safety and operating efficiency, the train scheduling and control system needs to grasp the precise location information of trains in real time. [0003] In the current rail transit system, train positioning still mainly depends on the construction of special trackside and on-board positioning equipment for train position positioning, and the investment cost is relatively high. [0004] Therefore, a new method for train positioning in rail transit needs to be proposed. Contents of the invention [0005] Embodiments of the present invention provide a train positioning method and system to solve the defect in the prior art that special equipment is required for train positioning,...
