METHOD OF SETTING UP DIGITAL RADIO CHANNEL FOR TRAIN ACS DATA TRANSMISSION Russian patent published in 2011 - IPC B61L25/02 

FIELD: transport.

SUBSTANCE: invention relates to railway transport and may be used for setting up radio data digital transmission channel for train ACS. Proposed method comprises using satellite navigation system to determine locomotive coordinates with data update frequency of 2 to 3 seconds.Coordinates are transmitted to onboard data control system that references locomotive location coordinates to railway route and generates messages on locomotive location referenced to common time to be transmitted via radio communication network to central switchboard and, further on, via data control server of railway central dispatcher station, to traffic time-table observance data generation unit. The latter compares received data with preset train time-table. Results of comparison are transmitter to dispatcher monitor and, via data control system and digital radio communication network, to locomotive onboard data control system to inform locomotive operator on deviations from time-table for him to take train control decision.

EFFECT: train motion automated control.
