Monitoring method and system of radio block centers and radio block centers

Abstract

The embodiment of the invention provides a monitoring method and system of radio block centers and the radio block centers. The method includes the steps that a first radio block center judges whether a first message sent by a second radio block center is received or not in a preset time quantum, and the first radio block center is adjacent to the second radio block center in physical positions; when the first radio block center judges that the first message sent by the second radio block center is not received in the preset time quantum, breakdown of the second radio block center can be determined. According to the technical scheme, an efficient RBC monitoring scheme is provided, an RBC serving as an HOV RBC can recognize the state of an RBC serving as an ACC RBC all the time, therefore, when RBC switching is carried out on a train, RBC switching can be carried out when the RBC serving as the ACC RBC is under a normal state, and safety of a train control system can be effectively guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of train communication, and in particular, to a monitoring method and system for a wireless block center, and a wireless block center. Background technique [0002] The Radio Block Center (RBC) is a very important signal device in the train control system such as China Train Control System 3 (CTCS-3). RBC communicates with other signal systems on the ground (such as centralized traffic Control (Centralized traffic control; CTC) system, interlocking (Interlocking; IL) system, temporary speed limit server (Temporary Speed ​​Restriction Server; TSRS), etc.) for data interaction, and send control information to trains equipped with on-board equipment of the train control system. Car information, control the operation of the train. The jurisdiction of one RBC is generally about 100KM, and multiple RBCs are deployed on one passenger dedicated line, so RBCs need to be switched during trai...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: in the prior art, adjacent RBCs do not monitor each other, and cannot effectively identify the state of the opposite end, for example, the train is between adjacent RBCs When switching, the HOV RBC is not sure whether the ACC RBC is normal, but directly switches to the RBC of the train

When the ACC RBC fails, the HOV RBC will think that the RBC switch has been completed for the train, resulting in a large safety hazard in the RBC switch process. Therefore, it is urgent to provide a RBC monitoring method to effectively ensure the train control system. security
