Abstract

The invention discloses a method for supplying and transmitting voice, data, static pictures, dynamic pictures, etc. to railway emergency communication by utilizing the existing sectional cables and communication column resources of railways so as to realize multimedia service transmission in the railway emergency communication. The technical proposal comprises the steps of: establishing an emergency command center taking railway bureaus as a unit, fitting out a central side emergency communication access device and realizing point-to-point emergency communication and point-to-multipoint emergency communication; according to the site geographical conditions and the existing line conditions of the railway line at the current section, fitting out emergency communication site side and/ or station side devices which can carry out point-to-point emergency communication and point-to-multipoint emergency communication with the central side emergency communication access device. The invention also discloses a device for realizing multimedia service transmission in the railway emergency communication.

Description

technical field [0001] The invention belongs to the field of railway emergency communication, in particular to a method and equipment for realizing multimedia service transmission in railway emergency communication. Background technique [0002] With the rapid development of my country's economy, the railway passenger and freight capacity has also developed rapidly. From April 1, 1997 to April 18, 2007, six major railway speed increases were carried out, from the initial 80- From 100 kilometers per hour to the sixth large-scale speed increase, the current maximum operating speed is more than 200 kilometers per hour, and some sections of the Beijing-Harbin, Beijing-Shanghai, Beijing-Guangzhou, Jiaoji and other speed-up trunk lines can reach 250 kilometers per hour. The increase in train speed also puts forward higher requirements for railway safety and emergency rescue work. Once an accident that affects the normal running safety of the railway occurs, how to quickly eliminate...
