PASSAGE BARRIER WITH A SENSOR TECHNOLOGY FOR DETECTING THE PRESENCE OF A PERSON INSIDE THE PASSAGE BARRIER

摘要

The present invention relates to a passage barrier comprising at least one barrier element that can be swivelled around a swivelling axis inside a swivelling area, at least one sensor technology that detects the presence of a person in the swivelling area and that comprises at least one sending unit emitting detection waves a s well as at least one reception unit and an electronic evaluation unit for evaluating the output signals of the sensor technology, wherein the sending unit and the reception unit are located such that a detection wave extending from the sending unit towards the reception unit extends through the swivelling area of the barrier elemen t and wherein the barrier element is at least partially made of a detection wave transparent material. Furthermore, the present invention relates to a method for operati ng a passage barrier according to the invention.
