Train operation safety protection system without secondary train occupation detection equipment

Abstract

The invention discloses a train operation safety protection system without secondary train occupation detection equipment, and the system comprises an initial train position marking module which enables a dispatcher to mark the section occupation information corresponding to the initial train positions of all trains manually through ATS before the system is powered on, a train tracking initialization list module which is used for initializing a train tracking list by the ATS according to the marked section occupation information and sending the train tracking initialization list to the trackside ZC; and a running train position tracking module which is used for tracking the positions of all trains by the trackside ZC in the running process of the trains. According to the invention, the train operation safety protection can be realized when no secondary train occupies the detection equipment, and the safety protection problem of the signal system when no secondary train occupies the detection equipment for auxiliary protection is effectively solved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to rail transit safety protection technology. Background technique [0002] In the existing urban rail transit CBTC signal system, the trackside ZC forms a mobile authorization through the ground track equipment status information (such as turnouts, signal machines, secondary train occupancy detection equipment, etc.) Send to the on-board equipment of all trains under the jurisdiction of ZC, and then the on-board equipment calculates the train target distance mode curve according to the driving permit to monitor the train operation in real time to prevent the train from overspeeding and overturning or rear-end collision with the train in front. After the train is degraded, the CBI will occupy it according to the secondary train Detection equipment, turnouts, signal machines and other trackside equipment, after safe interlocking logic processing, establish corresponding train ro...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the operation safety protection under the train degraded mode (non-CBTC mode) must rely on the secondary train occupancy detection equipment on the trackside for auxiliary safety protection, which leads to relatively large expenses in system maintenance and procurement costs. The workload of system debugging is relatively large, and it is not conducive to the upgrading and transformation of subsequent lines
