Downgrading management system of train control system based on train-train communication

Abstract

The invention relates to a downgrading management system of a train control system based on train-train communication. The downgrading management system comprises a safety equipment trackside TKTC system, a safety equipment ID device and a safety equipment ID reader, wherein the safety equipment trackside TKTC system is in communication connection with a vehicle-mounted CC, a safety equipment trackside TKIC, an ATS and the safety equipment ID reader; the safety equipment ID device is in communication connection with the safety equipment ID reader correspondingly; and when the vehicle-mounted CC fails or the train-ground wireless safety communication fails to downgrade, the safety equipment trackside TKTC system performs tasks instead of the vehicle-mounted CC. Compared with the prior art,the downgrading management system can still maintain the normal operation of a failed train and other trains when the vehicle-mounted fault of the train control system based on the train-train communication is downgraded, and the availability and safety of the whole system are ensured.

Description

technical field [0001] The invention relates to a rail transit signal system, in particular to a train control system degradation management system based on vehicle-to-vehicle communication. Background technique [0002] The traditional urban rail transit CBTC (communication-based automatic train control system) signal system sends a position report to the trackside ZC (zone controller) through the active positioning of the on-board CC (car signal system) system. Reports and status of wayside equipment are calculated and provided for movement authorizations for each train. The new generation of CBTC signaling system adopts a vehicle-to-vehicle communication method. The on-board system applies for line resources to the trackside target controller, and the target controller allocates line resources and informs the on-board system. On this basis, the train directly sends The location information requested by the preceding vehicle is used to calculate its own movement authoriza...

Problems solved by technology

[0003] It is precisely because the line resources are applied directly from the vehicle to the trackside, and the movement authorization of the following vehicle requires the train position of the preceding vehicle. If the vehicle-mounted system fails or the wireless security communication between the vehicle and the ground is downgraded, resources will not be allocated for this train, and the following vehicle will also be unable to allocate resources. The movement authorization cannot be calculated, and the operation of the two trains before and after is blocked. Manual intervention is required to allocate resources, which affects system availability; to safety hazard
