The invention relates to railway automation and telemechanics, in particular to track devices for fixation passing wheel axle of a transport means of a controlled track section and creating control data of track occupancy. A system control sensor of track occupancy comprises a block of forming a primary signal adopted to be mounted quite near a rail, wherein the block of forming a primary signal comprises at least three coils and at least one generator feeder, wherein the sensor comprises a block of the primary signal recept adopted to receive corresponding primary signals from each coil, a block of signal transformation adopted to transform separate signals provided from the block of the primary signal recept to a compound digital signal and a transmitter adopted to transmit the compound digital signal. Thus, the claimed invention provides reliability growth of the system control sensor of track occupancy due to an optimum three-channel structure and enhancement of transformation information noise immunity and also provides increase of reliability and accuracy of measurement of impacting of a running unit on the system sensor in passing a controlled track section. The claimed invention also provides reduction of the sensor power consumption and increase of sensor functionality as a whole. In the proposed invention all sensor radio elements, except for the coils, are arranged on a small plate, which proves the sensor simplicity, and the information transmission in a digital form with protective coding provides higher stability to noises. |
