The invention relates to railway automatics and telemechanics, in particular the track devices for recording the passage by a vehicle wheel axle of controlled track section of the path and formation of data of track occupancy control. A sensor of track occupancy control system comprises a unit of formation of the primary signal made with possibility of installation in close proximity to a rail, where the unit of formation of the primary signal comprises at least three induction coils and at least one generator for their powering. The sensor comprises a primary signal receiving unit adapted to receive respective primary signals from each of the inductance coil, a signal conversion unit made with possibility of conversion of individual signals from the reception unit into a composite digital signal and a transmitter adapted to transmit the composite digital signal. Due to optimal three-channel design and improvement of noise immunity of data transmission the system provides for reliability of the system sensor, improvement of reliability and accuracy of measuring the impact of a mobile unit on the sensor during passage of the control section of the track, and reduction of power consumption of the sensor and improvement of functionality of the sensor as a whole. |
