Abstract

The invention discloses an information transmission and distribution method for subway dispatching communication. The method is characterized in that a server and clients are included, wherein the server comprises a first data receiving module, a first data processing module, a first data sending module, a first parameter configuration module, a link management module, and an abnormality processing module; and each client comprises a second data receiving module, a second data processing module, a second data sending module, and a second parameter configuration module. The method disclosed bythe invention has the advantages that a safe and transparent data transmission channel is provided for data interaction during subway communication, and distribution priorities are decided based on priorities and the sizes of data transmission packets; data transmission among multiple dispatching consoles as well as between a CAD server and centralized network management devices can be guaranteed;and accurate and effective data transmission in a subway wireless communication system can be conveniently achieved.

Description

technical field [0001] The invention belongs to the technical field of data transmission and distribution, and in particular relates to an information transmission and distribution method for subway dispatching communication. Background technique [0002] As a wireless dedicated dispatching communication system, wireless broadband trunking has played an important role in the command and dispatch of transportation, electric power, logistics and other industries because of its large bandwidth, high speed, and the ability to transmit voice, data, images, and videos. . [0003] The wireless communication system in the subway usually uses the traditional TERA cluster to complete all dispatching functions, but with the requirements of subway train safety and subway site monitoring, there is an urgent demand for multimedia cluster communication capabilities including video; but the traditional It is difficult for existing access technologies to meet the technical requirements of b...
