Abstract

The invention provides a satellite precise positioning system for trains. The satellite precise positioning system for trains comprises a train-loaded management system, a ground train monitoring center system and a satellite precise positioning subsystem, wherein the train-loaded management system is used for outputting satellite data and train state data to a train nearby and the ground train monitoring center system through a wireless network in combination with train ID information; the ground train monitoring center system is used for processing the received data, and the ground train monitoring center system is further used for information transmission between one train and the ground, train security monitoring, train tracking, data recording and state warning; and the satellite precise positioning subsystem comprises a satellite data system, a satellite differential reference station and a train dynamic position calculating unit. The satellite precise positioning subsystem for the trains achieves precise positioning on the trains, and is simple in structure, high in operational efficiency and low in operational cost.

Description

technical field [0001] The invention relates to the technical field of precise positioning, in particular to a satellite precise positioning system for trains. Background technique [0002] At present, the current dynamic tracking method for running trains in the railway system is to track the position of the train based on the occupancy and clearing status of the signal equipment track circuit collected by the Railway Bureau TDCS on-site, and use the wireless train number check system to track the train number Automatically check and obtain the train number, and realize the tracking and judgment of the position and movement of the running train. [0003] Whether it is the automatic train control system (ATC) in the railway rail transit system, or the high-speed train control system (CTCS) and other systems, and the track circuit, wired, wireless and wireless block center (RBC), in the case of severe Geological disasters such as meteorological conditions, lightning and high...
