A broadband and narrowband fusion communication information system for railway passenger stations

Abstract

The invention discloses a railway passenger station broadband and narrowband fusion communication information system. The system comprises a central exchange server, an operation management system, a DMR digital wireless communication system, a broadband wireless communication system, analog-to-digital conversion equipment and an analog interphone. The analog interphone communicates with the analog-to-digital conversion equipment through an analog wireless channel. The analog-to-digital conversion equipment is interconnected and intercommunicated with the DMR digital wireless communication system through a DMR channel. The operation management system, the DMR digital wireless communication system and the broadband wireless communication system are connected with the central exchange server through a travel service private network, and data intercommunication among the operation management system, the DMR digital wireless communication system and the broadband wireless communication system is achieved through the central exchange server. According to the invention, different communication systems are accessed to the central exchange server, and the central exchange server performs registration, management, ID mapping and data coding format conversion on each system equipment to exchange voices and data of different systems, so that cross-system voice and data fusion communication is realized.

Description

technical field [0001] The invention relates to the technical field of railway traffic, in particular to a broadband and narrowband fusion communication information system for railway passenger stations. Background technique [0002] The technical system adopted by the railway passenger station communication information system mainly includes three types: analog intercom system, DMR digital wireless communication system, and broadband wireless communication system represented by LTE / WLAN. Since technology upgrading is a process of gradual change, the current three technologies The system coexists. [0003] Analog communication is still widely used in the railway industry. In order to connect analog voice to the system and intercommunicate with the digital system, a digital-to-analog conversion device is currently used. When the analog walkie-talkie initiates a call, the digital-to-analog conversion device will receive the analog signal. Convert the signal to a digital signa...
