Railway dispatching order transmission system and transmission method thereof

Abstract

Aiming at the defects of limitation of radio communication on a communication distance and a channel bandwidth in the prior art and high maintenance cost and long fault treatment cycle of GSM-R (Global System for Mobile Communications for Railway), the invention provides a railway dispatching order transmission system and a transmission method thereof which can overcome the defects. The railway dispatching order transmission system comprises a vehicle-mounted terminal, a communication server and a data processing server, wherein the data processing server is used for setting up a dispatching order and sending the set-up dispatching order to the communication server; the communication server is used for sending the set-up dispatching order to the vehicle-mounted terminal through a GPRS (General Packet Radio Service) or a 3G wireless communication network; the vehicle-mounted terminal is used for sending response to the set-up dispatching order to the communication server through the GPRS or the 3G wireless communication network; and the communication server is also used for sending the response received by the vehicle-mounted terminal to the data processing server.

Description

technical field [0001] The invention relates to the field of railway dispatching, in particular to a railway dispatching command transmission system and a transmission method thereof. Background technique [0002] The railway dispatching system has always been an important part of the railway traffic command system. It is an important guarantee for traffic safety and transportation efficiency. The transmission method and efficiency of dispatching orders directly affect the safety of railway transportation and production efficiency. [0003] At present, among the wireless dispatch command transmission methods adopted by domestic railways, the wireless data transmission channels of dispatch commands between trains and ground adopt 400MHz, 800MHz, 400KHz radio communication channels and GSM-R transmission channels. Among them, the first three belong to radio communication methods. Due to the limitation of communication distance and channel bandwidth, they are mainly used for vo...
