Device and system for monitoring the transit through passages

Abstract

The present invention relates to a device (2) for monitoring the transit of a user or of a land vehicle through a passage (or opening, or considerable area, hereinafter referred to cumulatively as “passage” for brevity's sake), comprising: a receiver-transmitter (5) of short-range radio signals configured to: transmit data indicative of a unique recognition code of the passage (ID_2); receive data indicative of a confirmation of receipt of a unique recognition code (ID_1) and indicative of an identifier of a user present inside the set cover angle (3); a processing unit (20) configured to: a) receive a first presence detecting signal (S1) having a value that is indicative of the presence of the user and of the vehicle inside the set cover angle (3) and generate, as a function of the value of the first presence detecting signal (S1), a second signal (S2) that carries data indicative of said unique recognition code (ID_1); b) calculate, with great precision, at set intervals of time (ti), the distance (di) and the angle (αi) with respect to a fixed directrix of said set orientation of the device; c) determine the trajectory (TRJ) of the user or vehicle approaching the passage on the basis of a time sequence of calculated distances (di) and angles (αi); d) if said trajectory (TRJ) is within the activation area (4) of the passage and approaches the passage, generate a command signal (S3) to open the passage and enable the user or the land vehicle to pass through. The invention also relates to a system (1) for monitoring the transit of a user or of a land vehicle through a passage.
