Abstract

Restricted area user access control and monitoring system and method is described a restricted area user access control and monitoring system and method that does not require physical contact of the user with the equipment and provides monitoring through images entering users in a restricted access (air) area by registering the entry of authorized users (100) and unauthorized users (110) joining with a duly authorized user (100) by recording images by video (20) and flags (30).

Description

FIELD OF RESTRICTED USERS ACCESS CONTROL AND MONITORING FIELD OF THE INVENTION The present invention describes a restricted area user access control and monitoring system and method. More specifically, it comprises an access system applied to devices that do not require the user's physical contact with the equipment and provides monitoring through images of incoming users in a restricted access area, recording the entry of unauthorized users and users who enter with a duly authorized user through electronic images and controls.

BACKGROUND OF THE INVENTION

In applications where flow control is required, various ways of validating or preventing passage are used. The most common case are ratchets or locks composed of mechanical arms arranged at angles of 90 ° (four arms) or 120 ° (three arms). In this case the user physically interacts with the arms, forcing the rotational movement of the device to allow its passage through the lock or ratchet, if properly validated. Rotation movement can be exclusively user-driven or motor-assisted and, if the passage is not validated, the ratchet prevents rotation, blocking the passage of any user.

An alternative method that requires no physical user contact with the equipment provides for the activation of sliding doors that block or allow user access through passage monitoring, usually by infrared optical sensors that monitor the user's passage by opening the doors. when the ticket is validated.

In the case of devices in which the user's physical contact with the equipment is not made, two main characteristics are explored: the passage of users without access permission and the monitoring of entrance of “ride” users, that is, the user who takes advantage of it. access by a user duly authorized to pass along the lock.

When a user signs in with a properly authorized user, the system detects and the doors automatically close, sometimes even preventing the authorized user from passing. This block is usually accompanied by audible and / or visual warnings, allowing action by security personnel. However, the system does not register the validated user who allowed access for a second non-validated user.

Thus, the object of the present invention is a restricted area user access control system that records incoming users' images, validating or not their entry, and providing the registration of images and events related to the entry of non-validated users. or the entry of non-validated users together with validated users - hitchhikers.

DETAILED DESCRIPTION OF THE INVENTION

For the purposes of the present invention, the following terms are conceptualized: "restricted area" (AR) comprises an area of restricted access to authorized users always positioned opposite the user who is about to enter the locking area (AB), said restricted area limited by physical and / or electronic means, which may be anterior to the blocking area and posterior to the blocking area (bidirectional control) or just prior to the blocking area (unidirectional control). “Blocking area” (AB) comprises an area where individual flow of users is laterally limited by barriers. The user access control and monitoring system in restricted areas, object of the present invention, comprises a pair of barriers (10) arranged parallel and spaced, so that in the gap between the barriers (10), here called the locking area ( AB), the flow of users who are individually directed towards the restricted area (AR) that can be unidirectional or bidirectional, said restricted area by doors or similar (40) or by an access control agent allows entry into the restricted area only to users with validated access (100).

In the initial area of the locking area (AB) is arranged a user identification device (60) interconnected to a processor, said identification device (60) can be selected, for example, from biometric devices, barcode reader or similar. , magnetic stripe, contactless radio frequency cards, among others.

In barriers (10) are provided indicator lights (30) driven by the processor that accompany the movement of each user through the locking area (AB) to the access door (40), said indicator lights (30) which preferably have a specific color. (31) to signal users with authorized access (100) and a specific color (32) to identify users with unauthorized access (110), making it easier for security officers to view.

The indicator lights (30) can be LED bars, laser beams, lamps, LCD, plasma or LED light displays, or the like.

A camera (20) interconnected with the processor captures images of users (100) and (110) entering the lock area (AB), as shown in figure 2. Data obtained by the identification device (60) is sent to the processor to check user status - whether authorized (100) for restricted area (AR) entry or unauthorized (110). At the same time, the processor receives the image obtained by the camera (20) and stores the register. At the processor, a computer program analyzes the data received from the identification device (60) and compares it with the data previously entered in a database to indicate whether the target user has restricted area (AR) access permission.

If the user is allowed to enter the restricted area (AR), the processor activates the indicator lights (30) that indicate on the surface of the barrier (10) the authorization to enter by means of a specific color (31) agreed as the color that identifies the permission to access the restricted area (AR), as shown in figure 5.

If the user is not allowed (110) to enter the restricted area (AR), the processor activates the indicator lights (30) that indicate on the surface of the barrier (10) the access is not allowed by a specific color (32), signaling access control agent the movement of the unauthorized user towards the restricted area (AR). In this situation, the restricted area (AR) doors (40) remain closed, preventing entry, as shown in Figure 7.

In the case of two users entering the locking area (AB), the barriers (10) promote the individual passage of the users, so that a first user moves in front of a second user, and the data obtained by the identification device. (60) and camera images (20) are sent to the processor identifying whether each user is authorized for restricted area (AR) entry. The signals (30) accompany the movement of each user through the locking area (AB) by activating different colors that identify authorized access or unauthorized access.

As shown in figure 6, in the lockout area (AB) there may be more than one person, each with its indicative window lit according to the passage status of each user. When a hitchhiker (110) is detected, door (40) initiates the shutdown in such a way as to allow access control agents to guide the exit of the lockout area (AB) user to allow door opening (40) for the next authorized user (100).

In this situation, authorized user entry records (100) accompanied by the image and unauthorized user entry attempt records (110) are generated, and it is possible to identify “ride” users (110) and authorized users (100) who intend to facilitate the entry of an unauthorized user (110).

Optionally, the camera (20) records the user's image and by means of a specific face recognition computer program, for example, identifies the enabled user (100) and the non-enabled user (110), dispensing with the user identification device ( 60). In this situation, the processor activates the flags (30) to indicate the window indicating the passage status of each user, whether they are authorized (100) for restricted area (AR) entry or unauthorized (110).

The images captured by the camcorder 20 are sent to the processor where they are stored and analyzed, recording the user's movement through video analysis algorithms. Next, the user detected by the computer program is associated with the data received from the identification device (60). The processor activates the lighting devices (30), opening a specific color status window that follows the user's travel through the lockout area, depending on the authorized (100) or unauthorized (110) user situation, freeing the user from entering. (100) in the restricted area (AR). Lock area (AB) data is sent to a server (control center) that receives equipment images, allowing access to events related to access authorizations, access denials, video analysis and lock configuration.
