METHOD OF CONTROLLING TRACK STATE

摘要

FIELD: transport.SUBSTANCE: invention relates to railway equipment, namely, to railroad ACS and telemetry hardware and be used for traffic control. Proposed method consists if feeding AC signal to one track circuit while resistor with rating equal to or smaller than specified train shunt is periodically connected to opposite track end at definite frequency. Occurrence of pulse variations in current and/or current phase relative to reference voltage is registered at track feed and/or relay ends. Occurrence of said variations is taken to indicate sound or cleared state of the track while availability of said variations are considered to warn about occupied and/or faulty state.EFFECT: higher reliability of track state control.
