Embodiment Construction

[0045] figure 1 A simple embodiment of the system of the invention is shown, comprising a first tag 1 and a second tag 2 mounted on the front end 3 and the rear end 4 of a vehicle 5 respectively. In the drawings, the vehicle 5 is an overhead monorail moving along the track direction 7 on the track 6 , so the tags 1 , 2 are mounted on the top of the vehicle 5 . It should be noted that the system and method of the invention can also be implemented for vehicles running on a track comprising two guide rails, but also for any other guided vehicles. Where the train moves on top of the track, the tags are preferably mounted on the bottom or sides of the train.

[0046] Next to the track 6, a plurality of label counting units 8, 9 are installed, each label counting unit 8, 9 delimiting one end of a track section A, B, C. Each tag counting unit 8 , 9 comprises two tag readers 10 a , 10 b , 11 a , 11 b which are separated by a distance from each other along the track direction 7 . W...

Abstract

The present invention discloses a system and method for determining track occupation. The system for determining track occupation of a track section (B) comprises: a first and a second tag (1a, 1b, 2a, 2b), the first tag (1a, 1b) being mounted at the front end (3) and the second tag (2a, 2b) being mounted and the rear end (4) of a vehicle (5); a first and a second tag counter unit (8', 9'), the first tag counter (8') unit being mounted at one end and the second tag counter unit (9') being mounted at the other end of the track section (B), each tag counter unit (8', 9') comprising two tag readers (10a, 10b, 11a, 11b) and a counting device (12a, 12b, 13a, 13b) for incrementing or decrementing a counter value; and an axle counter evaluator (ACE) connected to the counting devices (12a, 12b, 13a, 13b) of both tag counter units (8', 9') for evaluating whether the track section (B) is free or occupied in dependence of the counter values of the counting devices (12a, 12b, 13a, 13b).

Description

technical field [0001] The invention relates to a system for determining track occupancy of a track section within a track, said system comprising a first tag and a second tag, each tag comprising a transponder, such as an RFID transponder, the first tag being mounted on a vehicle's The front and second tags are mounted on the rear end of the vehicle. Background technique [0002] Such a system is known from document US 2011 / 0130899 Al. [0003] Typically, axle counting systems are used to determine the track occupancy for guided vehicles, for example trains. Such an axle counting system is http: / / www.thalesgroup.com / Portfolio / Documents / FieldTrac6315AzLM / published in , and includes an axle count evaluator and a detection point with two independent sensors at each end of the track section. The mechanism of the detection point is based on the electromagnetic field being affected by the iron wheel. The detection point can detect the direction of the vehicle through the ...
