Abstract

The system for detecting vehicles in transit along a track 2 comprises: a transmitter unit 16 and 12a located on one side of the track 2, having a plurality of infrared light-emitting diodes 17 and 12a which are multiplexed and modulated at a predetermined frequency, with a height essentially equal to the height of the wheels of the vehicle in transit; a receiver unit 18 and 14a located on an opposite side of the track 2, having a plurality of infrared light detectors 21 and 15a, with a height essentially equal to the height of the wheels of the vehicle in transit; and an electronic apparatus 22 for processing the electronic signals generated by the light detectors 21 and 15a, and comprising means of detecting the presence of a wheel and therefore an axle of the vehicle between the transmitter and receiver units. <IMAGE>
