Abstract

The embodiment of the invention provides a train dispatching system. The system comprises a main cluster base station, a standby cluster base station, a main EPC module, a standby EPC module, a main SCC module, a standby SCC module, a dispatching information server DIS and a dispatching desk; when the main SCC module is in a normal working state, a cluster terminal arranged in a train is registered to the main SCC module; when the main SCC module is in a fault state, the cluster terminal is registered to the standby SCC module; when the main cluster base station and the main EPC module are ina normal working state, the cluster terminal is randomly accessed to the main cluster base station and attached to the main EPC module; when the main cluster base station or the main EPC module is ina fault state, the cluster terminal detects a network fault through the air interface, re-accesses to the standby cluster base station and attaches to the standby EPC module. According to the embodiment of the invention, the communication reliability of the train dispatching system is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a train dispatching system. Background technique [0002] In the past rail transit industry, the train dispatching business generally used the Trans European Trunked Radio (TETRA) narrowband trunking system, and the Communication Based Train Control System (CBTC) business used the wireless local area network technology. With the development of LTE bandwidth technology and industry users' demand for high-quality voice and video and other big data services, the rail transit system gradually adopts LTE bandwidth technology to comprehensively carry train dispatching services and CBTC services. [0003] Among them, in the urban rail transit vehicle-ground integrated communication system (LTE-M) standard, it has been clearly stipulated that the architecture supporting data functions and trunking functions adopts the Broadband Trunking Communication (...
