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

specific Embodiment

[0052] The truck communication downgrade management system of the present invention is working in all in-vehicle systems, only the in-vehicle message and the ground ID reader message are received, and do not participate in train control.

[0053] Under normal circumstances, such as Figure 4 As shown, the car CC1, CC2, and CC3 two two communication, send the train position, and calculate the mobile authority according to the front train position, and the line resource is applied to the security device TKIC according to the train plan.

[0054] When the car CC2 is faulty, if Figure 5 As shown, the security device TKTC maintains the train information of CC2 according to the train position feedback from the last train information of CC2, and instead of CC2, communicates to CC1 and CC3, and instead of CC2, to the security device Tkic and ATS Communication. In this case, although the true CC2 has failed, due to the presence of the security device TKTC, all signal devices that need to be...

Abstract

The present invention relates to a train control system degradation management system based on vehicle-to-vehicle communication. The management system includes a safety equipment trackside TKTC system, a safety equipment ID device and a safety equipment ID reader. The safety equipment trackside TKTC The system communicates with the vehicle-mounted CC, safety equipment trackside TKIC, ATS, and safety equipment ID reader respectively. The safety equipment ID device communicates with the safety equipment ID reader. When the vehicle-mounted CC fails or the vehicle-ground wireless safety communication When the failure is degraded, the above-mentioned safety equipment wayside TKTC system replaces the on-board CC to perform tasks. Compared with the prior art, the present invention can maintain the normal operation of the faulty train and other trains when the on-board failure of the train control system based on train-to-vehicle communication is downgraded, ensuring the availability and safety of the entire system.

Description

Technical field [0001] The present invention relates to a rail traffic signal system, in particular, involving a rigid system downgrade management system based on a vehicle communication. Background technique [0002] Traditional urban rail transit CBTC (communication-based train automatic control system) signal system, the active positioning of the car CC (in-vehicle signal system) system, transmitting a position report to the rail (regional controller), ZC according to the location of each train The report and the orbital equipment status is calculated and the mobile authorization is provided. A new generation of CBTC signaling system, using car-car communication, the vehicle system applies for line resources to the track side target controller, the target controller assigns and informs the vehicle system on this, on this basis, the train directly The front car request location information is used to calculate its own mobile authorization. The vehicle communication system reduc...
