Abstract

The present invention discloses an information transmission distribution method of subway scheduling communication. A systematic framework of the method comprises a server and a client, wherein the server comprises a server data reception module, a server data processing module, a server data sending module, a server parameter configuration module, a server link management module and a server exception handling module, and the client comprises a client data reception module, a client data processing module, a client data sending module and a client parameter configuration module. The method of the present invention provides a safe and transparent data transmission channel for the data interaction in the subway communication, determines the priority of the data distribution by combining the data type and the size of a data transmission packet, and is used to guarantee the data transmission problem among a plurality of dispatching desks, a CAD server and the centralized network management. By the method provided by the present invention, the correct and effective data transmission in a subway wireless communication system can be realized conveniently.

Description

technical field [0001] The invention belongs to the 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 broadband m...
