Railway communication method and system

Abstract

The invention provides a method and a system for railway communication, and belongs to the communication field. The railway communication system comprises: an optical link terminal device arranged at a bus station or a GSM-R base station and connected with the external network of the bus station or the GSM-R base station, a fibre conversation pillar arranged at the interval between the bus stations or the GSM-R base stations and connected with the optical link terminal device through a fibre; and an optical network unit connected with the fibre conversation pillar. Because an EPON technique is applied to the interval communication along the railway, enough transmission bandwidth can be provided, basis of transmission of multimedia information between the interval and the bus station or the GSM-R base station is provided, communication capability at the point-to-multipoint railway intervals can be achieved, and usability, reliability and timeliness of communication between the railway intervals are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a railway communication method and system. Background technique [0002] With the rapid development of railway transportation, people put forward higher requirements for the safety and efficiency of railway transportation. The inter-section communication of the existing railway is to pass the call to the destination through the call post. The call post is to use various copper wires laid along the railway line to lead out a pair of taps at intervals of 1.5 kilometers between two stations. The tap is fixed on the post next to the railway. The call post is mainly used for telephone access. Its other function is as the access point of the static image device. The static image device can upload the picture to the railway bureau command by dialing. center. [0003] In the railway system, there are several application methods for inter-interval communication columns...

AI Technical Summary

Problems solved by technology

[0007] 1) In the existing railway communication system, since all the communication columns are connected in a serial manner, only one section communication column can communicate with the station in the same period of time, and the one-to-multipoint railway communication capability cannot be realized

[0008] 2) Due to the limitation of the existing railway communication bandwidth, it cannot meet the transmission bandwidth requirements of high-definition images, telephones, data and other multimedia information

[0009] 3) Since there is no dedicated emergency transmission channel, only one transmission channel can be temporarily connected after an accident occurs along the railway line, which cannot guarantee the timeliness, availability, reliability, and communication quality of information communication between the emergency scene and the emergency command center.
