Abstract

A digitized wireless train dispatching station radio station is mainly composed of a network unit, a mainframe unit, an MMI, a transmitter or receiver, a loudspeaker and a printer, wherein the mainframe unit comprises an antenna-feeder system, a duplexer, a low-frequency digitized 450MHz transceiver, a high-frequency digitized 450MHz transceiver, an information forwarding control module, an information analysis and comparison module, an information storage module, an information type fusion / extraction module, a data information input / output module, a voice information input / output module and an external interface module. According to the digitized wireless train dispatching station radio station in the communication system, the problems that at present, an existing wireless analog system train dispatching system is weak in anti-jamming capacity and lag in technology, can not provide the value added service and has a strong impact on informatization development of the railway communication technology are solved, and the technical support is provided for safe operation of trains.

Description

technical field [0001] The invention relates to a digital wireless train dispatching station radio, which belongs to the technical field of train wireless dispatching communication, and is used for stations along the railway line to realize the information between the digital station radio and dispatching, monitoring, stations other than the station, train dispatching operation terminals and other systems and equipment transmission device. Background technique [0002] The digital wireless train dispatching station radio station (abbreviation: digital station station radio station) is to realize the functions of train dispatching wireless communication system station receiving train running approach information, dispatching command, etc. Compared with the existing train dispatching station radio station, it solves the problem that the existing equipment adopts analog system The 450MHz frequency band has weak anti-interference ability, backward technology, and cannot provide ...
