Definitions

• the present invention relates to an access control device. More specifically, the invention relates to an access control device based on Bluetooth technology.
• the Bluetooth technology supports the signal direction detection feature, and therefore makes it possible to detect, with a certain level of precision and under determined conditions, the angle of origin of the signal emitted by a device, for example, but not limited to, a smartphone provided with an adapted application.
• the angle of arrival of the signal is normally expressed in polar coordinates with respect to the receiving antenna of the access control device, and it cannot distinguish between an arrival in front of or behind the signal that arrives from the device held by the person.
• Determination of the coordinates is one way of determining the position of the user with respect to a control barrier, such as for example a turnstile, a bar or a flap.
• the aim of the present invention is to provide an access control device that enables the use of Bluetooth technology, thus making it possible to discriminate between one person and another with precision so as to effectively determine access control.
• an object of the present invention is to provide an access control device that makes it possible to accurately determine the angle of arrival of the signal emitted by a device held by the person for whom to control access.
• Another object of the present invention is to provide an access control device in which the discrimination of the signal originating from a mobile Bluetooth device is performed using the least possible number of receiving antennae.
• Another object of the present invention is to provide an access control device that is highly reliable, easily and practically implemented and of low cost.
• an access control device comprising a barrier, characterized in that it comprises a single receiver which is adapted to detect the angle of arrival of a Bluetooth signal emitted by a mobile Bluetooth device carried by a person who has to pass through the barrier, said single receiver being arranged downstream of said barrier.
• the access control device generally designated by the reference numeral 1, comprises a barrier 2, such as for example a turnstile, and a receiver 3 which is arranged immediately after the barrier 2, i.e. downstream of the barrier, and is capable of detecting the angle of arrival of a signal emitted by a mobile Bluetooth device which must be located, so as to enable the control of access to the barrier 2 by the person who holds such mobile device.
• a barrier 2 such as for example a turnstile
• a receiver 3 which is arranged immediately after the barrier 2, i.e. downstream of the barrier, and is capable of detecting the angle of arrival of a signal emitted by a mobile Bluetooth device which must be located, so as to enable the control of access to the barrier 2 by the person who holds such mobile device.
• the receiver 3 comprises an antenna capable of detecting the angle of arrival of the signal, which is substantially directed upward, substantially in the direction of the person for whom to control access.
• the positioning of the receiver 3 makes it possible to reliably determine the position of the person, without resorting to triangulation of the signal using supplementary antennae.
• the position after the barrier 2 in fact makes it possible to ensure that there are no impediments to the propagation of the signal caused by the presence of other persons in the queue.
• the antenna 3 is in fact exposed only to the person who is passing through the barrier 2, who normally holds the mobile device either in a pocket or in the hand.
• the position after the barrier (downstream of the barrier) further ensures that the signal is not tangential to the body of the person, causing further problems of absorption and disturbance in the propagation of the signal in a straight line, which needs to pass through a significant portion of body.
• the position in a lower region, after the barrier, under a movable part 4 of the barrier ensures that, with its determination of the angle of arrival of the signal, it can be determined substantially uniquely that the mobile device is in the lane being monitored and that it is being held by the person closest to the barrier 2.
• determining the angle of arrival does not mean determining the distance of a person from a certain point, but rather means determining the angle of the straight line that runs from the receiving antenna 3 to the portable terminal that the person carries with him or her.
• the position of the receiving antenna 3 in a lower region, below the movable part 4 of the barrier, makes it possible to obtain the desirable effect that the straight line that runs from the portable terminal to the receiving antenna 3 always falls in the lane where the terminal is present.
• the positioning of the receiving antenna 3 after the barrier 2 in a position directed upward, i.e. toward the person who is passing through the barrier, makes it possible to effectively and precisely discriminate the person who is effectively right in front of the barrier, without running the risk of detecting the signal from other persons beside him or her.
• the device according to the invention fully achieves the set aim and objects, in that it makes it possible to accurately determine the angle of arrival of a Bluetooth signal emitted by a mobile Bluetooth device, carried by a person who is about to pass through a barrier and whose transit needs to be authorized by an access control.
• the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and to the state of the art.
