DESCRIPTION

SYSTEM AND PROCEDURE FOR ACCESS CONTROL TO AN ENCLOSURE

OBJECT OF THE INVENTION

The present invention relates to an access control system for a site through the use of wireless and/or mobile communication networks. The invention also refers to a control procedure associated with said system, incorporating both notable innovations and advantages with respect to the solutions of the state of the art.

BACKGROUND OF THE INVENTION

At present, the use of access control systems through electronic devices is increasingly widespread, in order to manage the entrance to premises. These can be controlled access areas, such as buildings, spaces or land, also being used, for example, in hotels, companies and public or official buildings.

Known access control systems are generally based on making different encrypted media available to users, in which a secret access or identification code or key is memorized. The encrypted supports transmit the access code memorized in them, or the identification code, through an interface, contact or not, to an access control device through which it must pass (for example, at a door ). The received code is verified in the access control device for entry authorization. These control devices are usually connected to a central in charge of their management, through fixed wired connections. A drawback of these known systems is that, in them, a personal encrypted medium must be delivered and assigned to the user, which implies a security risk in case of loss or theft. There is also the drawback that the administration of the access rights of the users and/or the assignment of the code are always linked to a control center. Therefore, in these systems, it is not possible to administer the user's access rights at certain points of passage, managing them from several independent control centers.

In this regard, it is known in the state of the art, as described in document WO 01/63425 A1, a system and a method for, by means of a mobile terminal, carrying out Wireless hotel search and selection, which allows reservation, access control and checkout of the room, as well as payment services for hotel customers. The mobile terminal comprises a mobile telephone and a processing unit, operating with wireless applications, for wireless communication with a hotel search and reservation server. A hotel room key device is transferred from the reservation system to the wireless device of the mobile terminal, and to the wireless door lock. When the terminal and the wireless door lock are within range, the door is unlocked.

In said access control system, the access control device is networked with the central, which involves significant expenses in wiring, which increases the time and costs of installing the access control system. On the other hand, a corresponding communication module is required in each access control device, further raising the costs of the system.

It is also known in the state of the art, as described in document WO 01/40605 A1, a method and a system for controlling access to a location secured by a locking mechanism controlled by a lock control unit, which can provide a high degree of flexibility and security. The method comprises the steps of storing a first access code in the lock control unit, being indicative of a predetermined access right to the location, storing a second access code in a second storage medium, using a key device electronically to request access to the location, comparing the second access code transmitted with the first access code, and activating the blocking mechanism where appropriate.

According to said document, the access control devices for data communication must be carried from the control center, which increases the costs of the system. In addition, the user who has several access codes memorized in his key device must select the one corresponding to the specific point through which he wishes to enter, which entails a waste of time, and may be considered somewhat cumbersome by the user.

Thus, and in view of the above, in this technical field, there is a need to develop an automatic system for access to premises or dependencies, more simplified and with lower implementation costs, without the need for any person to intervene. in the normal operation of the process.

Additionally, and in light of the high number of entrances that exist in certain installations and venues, the convenience of controlling who can cross them is observed, as well as registering who has done so or has tried to do so and at what time. This makes it necessary to develop a system that allows, without having to use keys, radio frequency cards or complex installations, to be able to manage its use in the most economical and simple way possible. Said system would also make it possible to overcome the problem caused when a key or a user identification device is lost, and the need that this entails for changing lock cylinders or reprogramming electronic locks urgently.

DESCRIPTION OF THE INVENTION

A first object of the present invention refers to a system, and an associated procedure, for the control of access to a room, which is put into operation when a user wants to access a space. Thus, while in solutions already known in the state of the art, the user receives on his mobile device a signal, or graphic symbol, preferably a QR code, which identifies him as a user authorized to access a space on a specific date and time , having to present said code to a reader linked to the access of the space in question, in the present invention the user is not identified by means of a QR code expressly generated to grant access to a space, on a date and time, but is identified by a series of associated unique credentials. Thus, in the present invention, the QR code identifies the access point of a specific space, and not, as in the state of the art, the user who wants to access this space. Preferably, it is the user who, with his mobile device, scans the signal, or graphic symbol, preferably a QR code, linked to the space to be accessed, and it is not, as in the state of the art, the user who shows said QR code to be scanned by a reader linked to the access point.

More specifically, one aspect of the present invention relates to an access control system for an enclosure, comprising:

i) at least one access identification device located in the vicinity of an access to said enclosure, said access being located within the range of at least one wireless communication network linked to the enclosure, where the access comprises opening means remotely in connection with control means of the enclosure, and in which the access identification device comprises at least one graphic signaling means; Y

ii) at least one mobile device comprising means for capturing one or more signals generated by the means of graphic signaling, and means for connection to said wireless communication network of the premises.

Advantageously in the invention, the enclosure control means are configured by means of one or more software and hardware applications to activate the remote access opening means, where said control means are in connection with a first verification module configured to determine that the mobile device is connected to the wireless communication network linked to the venue. Likewise, said control means are in connection with a second verification module, configured to determine that the capture means of one or more signals generated by the graphic signaling means of the mobile device (the capture means corresponding to the mobile device and the graphic signaling medium to the identification device), have captured at least one graphic symbol of the graphic signaling medium of the access identification device. In this way, it is not necessary to generate signals and, more specifically, a graphic symbol for each of the attempts to enter the premises through each of the accesses, which implies greater efficiency and savings in infrastructure costs, by no need for means of capturing signals at each of the entrances to the premises.

In a particular variant of the invention, the control means are centralized in a single location in the enclosure, carrying out the control function of the different identification devices of each of the accesses. Said variant represents a simplification of the integrating elements of the system, and therefore savings in terms of installation and maintenance efficiency. In an alternative variant of the invention, the control means are integrated into one or more of the different identification devices of each of the accesses. In said alternative variant, the control means located in one of the identification devices can either only carry out the control of said identification device in which they are integrated, or carry out the control of several of the identification devices, some of them which would not have to include their own means of control. This alternative variant offers greater design possibilities for the system, and greater integration of the various elements that make up the access control system for an enclosure.

On the other hand, it must be specified that said first and second verification modules are functional entities, and may be integrated into a single physical verification module, and may or may not form part of the control means themselves.

It should also be mentioned that wireless communication means a transmission of information at a distance and without the need for cables, and said transmission of information may be, in a non-limiting way, by means of a Wi-Fi network or, alternatively, by means of mobile data. Thus, the wireless communication network linked to the enclosure can be based both on a Wi-Fi network and on the transmission of information by means of mobile data. It follows that the mobile device can transmit the information to the control means wirelessly, in a non-limiting way, both through a Wi-Fi wireless communication network and through wireless communication via mobile data.

It should be added that the access control system of the present invention offers the advantage of being automated, preferably using, as a communication tool, the user's mobile phone and the wireless communication network of the premises as a transmission path. It is not necessary to store information for the process in the user's device and it can be changed in real time. Indicate that, on the computer or server responsible for managing access, generically referred to as means of control, an application is permanently running in which the staff in charge has entered who can access each of the dependencies, and dates and times can be specified. .

It should also be noted that the mobile device sends a first information related to said graphic symbol to the control means of the venue, either through the means of connection to said wireless communication network of the venue or, alternatively, through mobile data . On the other hand, the means of graphic signage can simply be a plaque on the wall with a sign, or graphic symbol, being the same permanently for said access. Even in the case of having a permanent graphic sign or symbol, the information associated with them can be dynamic, in the sense that the control means can assign them, depending on the circumstances, some data or others, which, for example, , whether or not they allow access to certain users on specific dates and times.

In this embodiment of the invention, the system comprises an authorization credential subsystem or module, by means of which it is checked whether the user of the mobile device is authorized to grant said access.

According to another embodiment of the invention, the graphic signaling means is an electronic device for graphic representation, so that there is the possibility of varying the signal, or represented graphic symbol, and even, to offer various information to the user in his attempt to access the premises through said access, such as showing the identification of who occupies the premises of said access, or what activity is being developed, in that moment inside. This option makes this system optimal for controlling access to classrooms, meeting rooms, multipurpose rooms, etc., in which the dedication to which they are intended varies. Likewise, the system allows registering who has carried out an activity and the time at which it was carried out. It should be added that, preferably, the electronic graphic representation device is a screen.

Thus, and according to a particular embodiment, the access identification device has display elements that allow specific information to be displayed, used both to identify the access point and to provide information to the user who tries to enter. Said information may alternatively be intended to be read with a mobile device, preferably a mobile telephone in which the user has previously been identified. Said identification step can be carried out, in a non-limiting manner, biometrically or by means of a personal password.

It should be noted that the identification device is preferably located outside the access door to the corresponding facility, being connected to the means of access control to the same, being able to use the wireless communication network of the enclosure in order to collect the information that must be displayed on the electronic graphic representation device.

In a preferred embodiment of the invention, the means for capturing one or more signals generated by the graphic signaling means comprise a camera, a device that is widespread in current mobile devices, such as mobile phones or tablets, benefiting from the resolution of image and ease of use of these devices.

According to another aspect of the invention, the mobile device is configured to process the information of the graphic symbol and send it to the control means, so that it can send both the graphic symbol itself and information or data assigned or linked to said graphic symbol.

Advantageously, the mobile device comprises biometric identification means, such as, but not limited to, the fingerprint, or facial features, in order to better identify the user of said mobile device, avoiding situations of impersonation. Thus, with the biometric identification of the user who executes it, it is ensured the correction of said identification, being able to subsequently activate the reading sequence of the identifier of the access that it wishes to cross.

More specifically, the graphic symbol that identifies access is a QR code, benefiting from its benefits of housing a substantial amount of information. It must be specified that the QR code can be static, that is, with fixed content, or dynamic, that is, its content can be modified, altering the information associated with it according to new needs.

Likewise, the QR code can be composed in an encrypted and personalized way for each installation or enclosure, facilitating automatic routing to a page, resident in the server computer, or generically, in the control means. Preferably using the combination of user and access, as well as the date and time, it is possible to verify whether or not the user is authorized to cross it.

As an alternative to the QR code, the graphic symbol can be a bar code, also presenting good information storage features.

According to another aspect of the invention, the wireless communication network of the enclosure is a Wi-Fi network, so that it is possible to establish reliable communication between devices without having to lay any cables between them. It is also possible to connect to said wireless communication network anywhere, as long as there is adequate coverage. In the case of being out of the coverage range, or directly, in the event of the enclosure's Wi-Fi network being cut off, security codes that allow access can be established in anticipation.

According to a preferred embodiment of the invention, the enclosure control means are located in the access identification device, so that there is greater physical integration of all the elements that make up the access control system.

According to another aspect of the invention, the enclosure control means are configured to activate the remote access opening means by controlling their power supply, depending on whether they are normally open or normally closed systems. In this way, the opening system is simple and robust, taking advantage of the installation of the door opening mechanism or corresponding access. Thus, for normally open systems, the remote activation of the access opening means will imply stopping the electrical power supply to the opening means, these going naturally to its position that allows the opening of the access. On the other hand, for normally closed systems, the remote activation of the access opening means will imply supplying electrical power to the opening means, these consequently going to their position that allows the opening of the access.

As a blocking system for access, any of the existing ones on the market can be used: door opener systems, electric locks, electromagnetic suction cups, etc. since the action of the access opening means will consist of controlling its power supply depending on whether, as mentioned, it is a normally open or normally closed system.

Thus, and if the access opening request is positive, the control means will return an opening order to the unit, specifically the mobile device, that issued it, proceeding to deactivate the access blocking system. In addition, and preferably, the result of the request will issue a spoken notification on the user's mobile device, for people with visual disabilities, and/or will be displayed on the screen of the mobile device, for people with hearing impairment. . In the event of a negative result, the user's mobile device will also be notified in speech, and the denial of the request will be displayed on the screen.

Advantageously, the enclosure control means are configured to activate the access opening means for a limited time, which will be previously configured in the control means. In this way, the opening is carried out exclusively for the user who has made the request, minimizing the risk that other unauthorized persons enter the premises through said access.

Additionally, the access identification device comprises a power battery, so that it can work even in the event of a power outage, which offers increased security, allowing the accesses to continue working even in said situation. of blackout

Another object of the present invention is an access control procedure for an enclosure, which comprises the steps of:

i) connection of a mobile device to a wireless communication network linked to the venue;

ii) identification of the user of the mobile device;

iii) reading by the mobile device of a graphic symbol located on an access identification device located in the vicinity of at least one access to said enclosure;

iv) sending a first piece of information related to said graphic symbol to control means of the enclosure;

v) checking by the enclosure control means whether the user of the mobile device is authorized to cross said enclosure access;

vi) activation of the means of opening access to the enclosure. In this way, it is not necessary to generate graphic symbols for each of the attempts to enter the premises through each of the accesses, which implies greater efficiency and cost savings in infrastructure, as signal capture means are not required. at each of the entrances to the site.

It should be specified that, preferably, step v) of checking whether the user of the mobile device is authorized to cross said access is carried out by the control means of the enclosure, specifically by an authorization credential module. And also preferably, step vi) of activation of the means for opening access to the enclosure is carried out by the control means of the enclosure. It should be mentioned that the graphic symbol can be, in a particular embodiment, an access identification code, or security code, with which access can eventually be allowed in the event of a cut in the wireless communication network of the premises.

It should be added that the process of establishing access control to a site begins with the configuration and parameterization of the identification devices, so that they are associated with a specific access. The control means in charge of access management send the information that must appear on their display devices or graphic signaling means. The control means can send different orders to each of the identification devices based on their occupancy table over time.

Consequently, said access control procedure offers an optimization of access management to multiple dependencies or premises by different users, without their limits, without the use of any type of self-identifying device that makes it possible. Nor does it require distributed controllers to manage access or specific wiring to enable it.

Advantageously, the access control procedure comprises a step of recording an attempt to access the premises, so that the date and time, and the result of the access request, can be known and subsequently reviewed.

According to another embodiment of the invention, the identification of the user of the mobile device is through their fingerprint and/or facial recognition and/or the validation of a username and password and/or the IMEI and telephone number combination and/or the combination of user and telephone number.

In this way, alternative modes of identification of the user of the mobile device are made possible, in a reliable and unambiguous manner.

Other characteristics and advantages of said system, and associated procedure, for controlling access to an enclosure, object of the present invention, will be explained in the detailed description of the same below, illustrating by way of non-limiting example in the drawings that the accompany.

Figure 1 shows, by way of illustration, an access control system (2) implemented in an enclosure (1) that has at least one wireless communication network (4), and control means (5). , said means being able to be a computer server, for example housed in one of the buildings of the enclosure (1). The control means (5) comprise, in its preferred embodiment, a first verification module (51), a second verification module (52), and an authorization credentials module (53).

Figure 2 shows, by way of illustration, a situation in which a user (7) tries to cross an access (2), for which he has to approach the identification device (3) located in said access (2) , and in particular to a graphic signaling means (31) where there is a signal (32) or, more specifically, a graphic symbol (32a). The user (7) uses his mobile device (6), in particular the capture means (61), usually a camera, to receive the signal (32), that is, to photograph the graphic symbol (32a). In different embodiments, the mobile device (6) can also preferably have connection means (62) and biometric identification means (63). The mobile device (6) thus establishes a connection with the wireless communication network (4) through the connection means (62), which is detected by the control means (5), which, after the appropriate checks, they issue an order to the identification device (3) to allow or not to cross the access (2) activating or not the remote opening means (33), respectively, which can work with electrical power (34) and, specifically , include a battery (35).

Figure 3 shows, by way of illustration, a user (7) who is capturing the signal (32) or graphic symbol (32a) with his mobile device (6), in particular with his capture means ( 61). Subsequently, and through its connection means (62), it issues said information to be collected by the control means (5). Additionally, it can issue additional user information (7) collected through the biometric identification means (63).

Figure 4 shows, by way of illustration, a block diagram of the most important elements of the access control system, which are specifically the identification device (3), the wireless communication network (4) and the control means (5). The identification device (3) comprises a graphic signaling means (31), also called representation and display device (T1), and a microprocessor (T2), forming the core of said identification device (3). Of Preferably, the microprocessor (T2) issues orders to the graphic signaling means (31) about the signal (32) or graphic symbol (32a) to be represented.

It should also be noted, as shown in figure 4, that the identification device (3) comprises remote opening means (33), which, as well as the representation and display device (T1) and the microprocessor (T2), They can work by means of an electrical supply (34), which can be delivered through a power supply transformer and a plug for connection to the electrical network (T6), and may optionally comprise a battery (35), being for example connected by means of a USB cable (T7). As can be seen in Figure 4, it is the microprocessor (T2) that orders the opening of the remote opening means (33), also called the access opening system (T5).

On the other hand, it should be mentioned, as can be seen in Figure 4, that the wireless communication network (4), or network connection (T3), and the control means (5), or computer/is responsible for managing accesses (T4), are in permanent interaction during the operation of the system. Thus, the control means (5) send information to the identification device (3), preferably to the microprocessor (T2), through the wireless communication network (4), and vice versa, the identification device (3 ), preferably from the representation and display device (T1), send information to the control means (5) through the wireless communication network (4), which may optionally be a bidirectional communication. It should be added that the control means (5) comprise, in a preferred embodiment, a first verification module (51), a second verification module (52) and an authorization credentials module (53).

It is worth mentioning that, according to a preferred embodiment of the invention, the access control system (2) to premises (1) consists of a wireless system with centralized control and a screen, located on the outside of the access (1), where the identification code of the same can be displayed, in the form of a graphic symbol (32a), preferably a QR code, as well as the information data that the user (7) who tries to access is deemed appropriate to know. Said user (7) must read, executing an application that he has on his mobile device (6), the QR code that is shown on the screen or means of graphic signaling (31). Said mobile device (6), for security reasons, and preferably, must be linked to the wireless communication network (4) of the enclosure (1). At that time, your request is sent to the access control means (5) (2). This message is composed by user identification (7) plus the information contained in the QR code. Once the authorization has been verified by the control means (5), the order is issued to the corresponding identification device (3) so that it activates the door opener or the electric lock and allows passage.

Optionally, the system of the present invention can be used to control access to enclosures (1) such as garages, locating it in the barriers that allow access to it, having associated the vehicle that tries to access, in particular by recognizing its license plate, with the owner of the vehicle, or user (7), who makes the request.

Thus, and as can be seen in Figures 1 and 2, the access control system for an enclosure (1) comprises:

i) at least one access (2) identification device (3) located in the vicinity of an access (2) to said enclosure (1), said access (2) being located within the reach of at least one network of wireless communication (4) linked to the enclosure (1), where the access (2) comprises remote opening means (33) in connection with control means (5) of the enclosure (1), and where the device of identification (3) of access (2) comprises at least one means of graphic signaling (31);

ii) at least one mobile device (6) comprising capture means (61) for one or more signals (32) generated by the graphic signaling means (31), and connection means (62) to said wireless communication network (4) of the enclosure (1); where the control means (5) of the enclosure (1) are configured by means of one or more software and hardware applications to activate the remote opening means (33) of the access (2), where said control means (5) are in connection with a first verification module (51) configured to determine that the mobile device (6) is connected to the wireless communication network (4) linked to the enclosure (1), and where said control means (5) are in connection with a second verification module (52) configured to determine that the capture means (61) of one or more signals (32) generated by the graphic signaling means (31) of the mobile device (6) have captured at least a graphic symbol (32a) of the graphic signaling means (31) of the identification device (3) of access (2).

It should be added that, as an option, and in order to simplify and reduce the cost of the installation, the identification device (3) incorporates, among others, a microcontroller and a screen or graphic signaling means (31) that allows the communication, in real time, between each of the accesses (2) and the server or control means (5) in charge of centralizing the management of the access permits to the facilities of the enclosure (1). This option leaves open the possibility that the person responsible for authorizing access can manage the request to open it from their own computer or mobile device (6).

It is relevant to emphasize that the user (7) who tries to access a dependency or access (2) must preferably meet at least two requirements: first, have their mobile device (6) connected to the wireless communication network (4 ) of the enclosure (1), and second, to execute the corresponding application, in which you must identify yourself, either biometrically or by means of your personal password when requesting access. The QR code displayed on the graphic signaling means (31) is read and, in this way, it will communicate to the system its intention to access the dependency in question.

This procedure makes it possible for the mobile device (6) of the user (7) to be a mere communication device, so any other type of wireless device could be used, connectable via Wi-Fi, Bluetooth, or radio frequency, in order to establish communication with the system. Said devices capable of wireless communication can be, without limitation, a tablet, a smart watch, and even, for example, a key ring or remote that could send a code via Bluetooth to the control means (5).

The management of the permissions granted to each user (7) referring to each of the controlled accesses (2) can optionally be modified, in real time, by the personnel in charge of such function, not having to carry out any type of update in the different accesses (two). Likewise, it is possible to vary, in real time, either immediately or preprogrammed, using an application designed for this purpose, the information to be displayed on a certain display device or identification device (3) and its graphic signaling medium.
