METHOD OF TRANSMITTING ALARM DATA BETWEEN RAILROAD CAR INVOLVED IN ACCIDENT AND CONTROL CENTRE AND CORRESPONDING DEVICE Russian patent published in 2014 - IPC B61L27/00 H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: group of inventions relates to transmission of messages between a train and a control centre. The method of transmitting alarm data between a first train involved in an accident and a control centre comprises steps of, if the working state of said train matches the accident, determining if the main radio link between the train and ground infrastructure with which a control centre is connected can be used. Otherwise an emergency radio link is established between the communication device of the first train and the communication device of a second train crossing the coverage area of said emergency communication means. After establishing a link between the trains, alarm data relating to the first train are transmitted and stored at the second train. Data relating to the first train are transmitted using a second link between the second train and the control centre. An on-board installed on the trains comprises a means of assessing the state of the train, a main communication means and a self-contained emergency communication device. The communication framework comprises said on-board systems, base stations and a control centre.

EFFECT: high reliability of data transmission.
