Embodiment Construction

[0028] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-2 An auxiliary train protection system based on Beidou navigation is shown, including GPS satellite 1 and Beidou satellite 2, orbit positioning equipment set on the track (specifically, track position positioning is completed through track circuits and transponders.) and set on The Beidou-GPS dual-mode receiver and on-board computer on the train 3, the train control center 4 and the GSM-R wireless network that the train 3 communicates with the train control center 4 when the track positioning equipment is normal. Among them, the track positioning equipment generates the track positioning information of the train; one function of the Beidou-GPS dual-mode receiver is to receive the train positioning information when the track positioning equipment is normal and invalid, and the other function is t...

Abstract

The invention provides an auxiliary train protection system and an auxiliary train protection method based on Beidou navigation. The auxiliary train protection system comprises a GPS (Global Position System) satellite, a Beidou satellite, track positioning equipment arranged on a track, a Beidou-GPS double-module receiver, a vehicular computer, a train control center, a GSM-R (Global System for Mobile Communication-Railways) wireless network for realizing bidirectional communication with a train when the track positioning equipment is normal, wherein the Beidou-GPS double-module receiver and the vehicular computer are arranged on the train; the system can supply more accurate positioning information with the coordination of a track positioning system when the train is in normal operation; the system supplies Beidou-GPS double-module positioning information for the train in the condition that the track positioning equipment loses efficiency, and can communicate with the train by using the Beidou bidirectional communication function without dependence on any ground communication equipment. With the adoption of the auxiliary train protection system, the train is automatically decelerated and even braked in dangerous conditions, so that the normal operation of the train system can be ensured and the auxiliary train protection system is used as a final protection barrier of the train; the security of the train is improved on the basis that the reliability of train positioning information can be ensured.

Description

technical field [0001] The invention relates to auxiliary protection of trains, in particular to an auxiliary train protection system and method based on Beidou navigation. Background technique [0002] The unbalanced distribution of transporting floating population and various material resources poses a severe test to my country's railway transportation, and the safe operation of railways is obviously a crucial factor to ensure the reliability of transportation. China Train Control System (CTCS) is divided into four levels, currently CTCS-2 and CTCS-3 are widely used. CTCS-2 checks the occupancy of the track through the track circuit, and transmits information such as the driving permit issued by the train control center to the train; informs the train line information through the transponder, and transmits information such as the temporary speed limit issued by the train control center. CTCS-3 checks the occupancy of the track through the track circuit; transmits the posi...
