Method And Device For Detecting A Passage Associated With An Access Door
First Claim
1. Method for detecting a passage associated with an access door, for example an immigration control point, a boarding gate or the entrance to a secure building in particular in order to guarantee the passage of one person only, characterized in that the profile of the person is determined by means of a vertical row of infra-red emitting cells (D1) arranged at the entry to the door opposite receiving cells connected to a control unit (CU) which manages the sampling and the frequency of emission of the signals and as a function of this profile, the access door is opened or remains closed.
