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.
