FIELD: trains control means.
SUBSTANCE: invention relates to means of monitoring track circuits and controlling movement of trains. In the technical solution, a track generator and a track receiver are installed at the station adjacent to the haulage to track the track circuits located between the station and the middle of the line by a two-wire linear circuit. On boundaries of welded track circuits in track boxes there installed are track transformers, band-pass filters, current switches, which are connected cyclically in turn to rail lines of rail circuit devices as per signals from counters. At the receiving ends of the rail circuits there are frequency converters, supply of power from the station track generator to the rail lines and from the rail lines to the station track receiver is carried out along the two-wire line. Power supply to rail circuits is supplied with pulses differing in phase, counters count pulses. Alternate cyclic connection of track circuits to track generator and track receiver is performed.
EFFECT: possibility to control conditions of track circuits using two-wire cable line.
