FIELD: railway transport. ^ SUBSTANCE: proposed method consists in registering last car and train head end magnetic pickups passing of control point. When train head end magnetic pickup enters the track, a signal with track section occupancy frequency is generated, controlled track section frequency is identified and section occupancy is recorded. When last train car magnetic pickup passes control point, a signal with section clearing signal is generated, section frequency is indentified and section clearing is recorded. Proposed device consists of track section clearing device comprising rectifier, capacitor and generator. Additionally, it incorporates two magnetic pickups and two floor pickups, every track section occupancy device comprising rectifier, capacitor, generator and two bandpass filters for every track section, communication line, input device and engineering support station. ^ EFFECT: higher reliability of control over track non-occupancy. ^ 2 cl, 2 dwg |
