System for checking the single crossing of a controlled passage
First Claim
1. A system for checking a single crossing of a controlled passage, comprising:
- an intercepting booth (1);
a first unit (2) for detecting a variation over time (t) of the weight (P) of one or more people (7) and/or things in a controlled passage (6) delimited by the intercepting booth (1);
a second unit (3) for detecting a variation over time (t) of a capacitance (C) of an electrical capacitor, the electrical capacitor comprising two metal armours, the controlled passage (6) being located between the two metal armours; and
an electronic programmed unit (8) with i) inputs (9) connected to at least the first unit (2) and the second unit (3), and ii) outputs (10) connected at least to an alarm unit (11) and to a device for controlling at least an opening and closing of a door (13) separating the controlled passage (6) from a protected area (14),wherein the electronic programmed unit is configured to compare a shape and amplitude of a first signal received from the first unit with a shape and amplitude of a second signal received from the second unit and, based upon the comparison, determine whether more than one person and/or thing has entered the intercepting booth (1) and, upon a positive determination that more than one person and/or thing has entered the intercepting booth (1), activate the alarm unit (11) and prevent an opening of the door (13).

Abstract
The system includes an intercepting booth (1) and at least two detecting units (2) and (3), of which the first one analyzes the variation over time of the weight of people or things penetrated into the booth, the second one analyzes the variation over time of the capacity of the electrical capacitor consisting of two metal armors (4) and (5) between which the controlled passage into the booth (1) is comprised. It further includes an electronic programmed processing unit (8) the inputs (9) of which are connected to at least the two detecting units (2) and (3) and the outputs (10) of which are connected to at least one alarm unit (11) and the elements for locking at least the door (13), of the booth (1) that separates the controlled passage (6) from the protected area (14).
