Abstract

The embodiment of the present application discloses a clock synchronization system based on a dispatching centralized system, which comprises a satellite timing instrument, a central clock server andan external clock server. The satellite timing instrument is used for providing synchronization time information to the dispatching centralized system; the central clock server is used for acquiring the synchronization time information provided by the satellite timer and providing the synchronization time information to the application server, the interface server, the communication server, the external clock server and the first-level workstation in the dispatching centralized system. A communication server acts as a station device clock server to provide synchronization time information to the station equipment under the jurisdiction; the external clock server is used for providing the synchronization time information provided by the central clock server to the signal centralized monitoring system in the pipe and other systems, and realizing clock synchronization between the dispatching centralized system and other systems.

Description

technical field [0001] The present application relates to the technical field of station control systems, in particular to a clock synchronization system based on a centralized dispatching system. Background technique [0002] CTC: Centralized Traffic Control, dispatching centralized system. The centralized dispatching system is a remote control and remote signaling system composed of telecontrol technology combined with railway transportation. [0003] The dispatching centralized system is built on the basis of the train dispatching command system, and consists of two levels: the railway bureau and the station. In addition to realizing all the functions of the train dispatching command system, the centralized dispatching system should also realize the functions of train marshalling information management, shunting operation management, comprehensive maintenance management, train / shunting route manual and automatic plan selection, decentralized self-discipline control and o...
