Abstract:
A device for counting passengers on a transportation vehicle, said counting device comprising:a detection device for detecting persons or objects and the direction of movement thereof, comprising: a radiation sensor arrangement for detecting electromagnetic radiation of the wavelength of visible and/or invisible light, which emanates from the person or object, and an evaluation unit that is connected to the sensor arrangement and that forms a variation signal which corresponds to a time variation of the radiation detected by the radiation sensor arrangement, wherein the detecting device further comprises a means for individualizing that is connected to the evaluation unit and that obtains information individualizing the object or person, and that is connected to a store that stores at least a portion of the variation signal and the information individualizing the object or the person as a characteristic parameter in association with the variation signal such that the detection device can discern between different objects or persons and identify a same object or person at different times, and wherein the detection device further comprises a means for determining a parameter that is connected to the evaluation unit and that delivers an additional signal, wherein the evaluation unit forms the characteristic parameter in dependance on the additional signal, wherein the parameter-determining means comprises a radiation source for radiation which can be detected by the sensor arrangement or alternatively or additionally to the radiation source comprises an additional sensor for detecting a person-individual signal; and a counter connected to the detection device; and wherein the detection device is adapted to be mounted above an entrance to the transportation vehicle.
