Abstract

A disclosure relates to a degradation management method for a versatile signal system, a device and a medium. The versatile signal system supports both the CTCS system for the national railway and the CBTC system for the urban railway; the method controls the safety of trains equipped with the CTCS system or the CBTC system on the same line, and effectively conducts degraded operation management; and the management method comprises switching between normal operation modes of the CTCS system and the CBTC system, switching between degraded operation modes, and switching between normal operation modes and degraded operation modes in a shared area. Compared with the prior art, the disclosure has the advantage that effective degradation operation mode management on trains running on a line under a CTCS+CBTC signal system is realized.

First claim

What is claimed is:

1. A degradation management method for a versatile signal system, wherein the versatile signal system supports both a China Train Control System (CTCS) system for a national railway and a Communication Based Train Control (CBTC) system for a urban railway; the method controls a safety of trains equipped with the CTCS system or the CBTC system on the same line, and effectively conducts degraded operation management; and the degradation management method comprises switching between normal operation modes of the CTCS system and the CBTC system, switching between degraded operation modes, and switching between normal operation modes and degraded operation modes in a shared area;
wherein the degradation management method allows the degraded operation mode switching only in the shared area;
wherein the degraded operation mode switching specifically comprises:
in the shared area, according to a status of a line device, completing an initial registration of an operating mode under a system to be switched first, and then exiting the operating mode of a current system while switching to the operating mode of a next system, thus realizing cancellation of the operating mode of the current system;
wherein for degraded operation mode switching in a collinear area, matching with conditions of an operation mode under a system to be switched according to a status of a trackside device, a vehicle-mounted device and a network device on current line is required, and only when the conditions of an operating mode under the system to be switched are met, can the switching be made.

2. The degradation management method for the versatile signal system according to claim 1 , wherein the degradation management method supports a collinear operation scenario and a cross-line operation scenario, the collinear operation scenario means that a CTCS line and a CBTC line share a same track, and the cross-line operation scenario means that a train can seamlessly run on the CTCS line or the CBTC line.

3. The degradation management method for the versatile signal system according to claim 2 , wherein in the collinear operation scenario, CTCS trains and CBTC trains are each equipped with a single-system vehicle-mounted device, only a CTCS system trackside device is arranged in a CTCS system area, only a CBTC system trackside device is arranged in a CBTC system area, and a CTCS trackside devices and a CBTC trackside devices are arranged in a collinear area of the CTCS system and the CBTC system.

4. The degradation management method for the versatile signal system according to claim 2 , wherein in the cross-line operation scenario, CTCS trains and CBTC trains are each equipped with a dual-system vehicle-mounted device, only a CTCS system trackside device is arranged in a CTCS system area, only a CBTC system trackside device is arranged in a CBTC system area, and a CTCS trackside devices and a CBTC trackside devices are arranged in a cross-line transition area.

5. The degradation management method for the versatile signal system according to claim 1 , wherein operation management modes of a CTCS and a CBTC are compatible in the versatile signal system, and the trains can keep a single operation management mode of the CTCS or the CBTC, or switch between the operation management modes of the CTCS and the CBTC, thus realizing the compatibility of the operation management modes under the versatile signal system.

6. The degradation management method for the versatile signal system according to claim 1 , wherein operation mode switching of the versatile signal system supports switching between the normal operation modes and degraded operation mode under the CTCS system and the normal operation modes and degraded operation mode under the CBTC system.

7. The degradation management method for the versatile signal system according to claim 1 , wherein the degradation management method supports operation modes switching between different systems in the shared area, stopping or not stopping, so as to ensure normal operation of trains in the shared area and smooth switching of the operation modes.

8. The degradation management method for the versatile signal system according to claim 1 , wherein implementation of the degradation management method is based on a same vehicle-mounted safety platform.

9. An electronic device, comprising a memory and a processor, wherein the memory stores a computer program, and the processor, when executing the program, implements the degradation management method of claim 1 .

10. A computer-readable storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements the degradation management method of claim 1 .
