TRAIN SPEED CONTROL DEVICE Russian patent published in 2006 - IPC B60L15/20 B61L3/20 

FIELD: railway transport; signaling and communication.

SUBSTANCE: invention relates to devices for transmitting tolerable speed signals at running along tracks between stations and at station and to control tolerable running speed of train. Proposed device to control train running speed contains section number coded combination generators 1, route number coded combination generator 16 and route setting signal shaper 2 connected by outputs with inputs of cab signaling signal shaper 2.1. Fitted on locomotive are block-section border detection unit 3, cab signaling unit, two distributors 5, 7, two storage units, distance meter, point communication channel receiver 9, covered distance pickup, speedometer, comparator unit, braking unit, train tolerable speed detection unit, re-coding unit 24, correcting unit 22, station section border detection unit 20, block section border detection unit 21, OR and AND gates and switch elements, cab signaling auxiliary unit 31, train tolerable speed auxiliary unit 32 and interference detection unit.

EFFECT: improved reliability and safety of traffic on section between stations at interferences created by traction current and transmission lines.
