Inter-city railway train control system based on satellite positioning technology

Abstract

The invention relates to an inter-city railway train control system based on a satellite positioning technology. The inter-city railway train control system comprises center equipment, trackside equipment and vehicle-mounted equipment. The vehicle-mounted equipment is in communication connection to the center equipment and the trackside equipment, separately. The center equipment comprises centralized traffic control system CTC and a resource management system RMU connected to each other. The trackside equipment comprises a positioning transponder for achieving precise train stopping. The vehicle-mounted equipment comprises a satellite positioning module for achieving precise train positioning. A train system with an integrated design idea integrates moving block, integrated equipment control of stations and automatic drive of the train, and bidirectional continuous vehicle-ground wireless communication is adopted, so that train operation is controlled by taking vehicle-mounted signalsas main body signals of train operation. Compared with the prior art, the inter-city railway train control system has the advantages of being high in positioning precision and the like under this circumstance of reducing the trackside equipment.

Description

technical field [0001] The invention relates to an intercity railway train control system, in particular to an intercity railway train control system based on satellite positioning technology. Background technique [0002] The INTXIS system developed based on CTCS-2 high-speed railway is the first signaling system in the world to apply automatic driving technology on high-speed railway. The system is a solution for the intercity railway signal system built in the C2+ATO mode. The system is equipped with automatic driving, automatic door opening and closing, and automatic return. Comfort and energy saving are achieved at the same time. The system is mainly composed of CTC, CCS, TCC, CBI, TSRS, ATP\ATO and other equipment. [0003] Since the speed of the intercity railway reaches 200km / h, the time interval of simultaneous operation should reach 3 minutes. In the case of such high-speed and high-density transportation, it is imperative to increase equipment stability, reduce...
