Description

[0001] The present invention relates to a beacon-based access control system and a method thereof,

The present invention relates to a beacon-based access control system and a method thereof. More particularly, the present invention relates to a system capable of improving user convenience by automating access control of a user by using a beacon based on bluetooth, and a method of operating the system.

In common houses such as apartments, officetels, etc., the common entrance is normally closed, limiting the access of outsiders. In addition to the common entrance, a door is installed in a place where authorized users can access, and the access of unauthorized persons is limited.

In order to open the door of the common entrance door, it is most common to input the password through the lobby phone. However, since the inputting action itself is troublesome, the convenience of the user is lowered. Also, since the risk of password leakage is high, the security effect is not high.

In order to solve the user convenience problem, a technique has been proposed in which a resident is provided with a radio frequency identification (RFID) card or a near field communication (NFC) card and the door is opened through card reading. However, since the proposed technique also requires user actions such as card-taking, card tagging, etc., the user-friendliness problem is still not solved.

Accordingly, there is a need for an access control system capable of improving the user's convenience by automatically opening the door when the user approaches the door without requiring a specific action for accessing the authorized user.

Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 illustrates an exemplary environment in which a beacon-based access control system in accordance with some embodiments of the present invention may be constructed. Particularly, FIG. 1 shows an example of controlling entrance and exit of a household occupant through a target door installed in a common porch.

The common porch shown in FIG. 1 refers to an entrance for connecting indoor and outdoor to a common house such as an apartment or an office building. The common porch is generally installed on the first floor of the building, but it may be installed in a passage connected to an underground or ground parking lot depending on the building structure.

Typically, the lobby phone 10 is installed adjacent to a common entrance door, and is used for calling a specific household, performing an authorization authentication required for opening a common entrance door, and the like. The rights authentication is performed by, for example, a method of inputting a password, fingerprint recognition, RFID, NFC tagging, or the like. However, as described above, the enumerated authority authentication method requires the user's positive behavior (e.g., tagging behavior, password input, etc.), and thus the user's convenience is low. In particular, in the case of a place where the same person frequently enters and exits, such as a common porch, the user has to perform the illustrated actions each time he / she enters or exits, so that he may feel more inconvenience.

According to some embodiments of the present invention, automatic access control may be performed without requiring the user's action using a beacon device, a user terminal 20 owned by the user, and a server communicating with the user terminal 20. [ That is, the door opening can be performed automatically when the user approaches the target door (e.g., the common entrance door). Accordingly, the user can access the target door more conveniently and safely.

The beacon device is installed adjacent to the target door. For example, the beacon device may be installed in the lobby phone 10. Hereinafter, for convenience of explanation, it is assumed that a beacon device is installed in the lobby phone. However, the scope of the present invention is not limited thereto.

In addition, the access control system according to some embodiments of the present invention may be constructed in various places where access control to the target door is performed according to the access right in addition to the common entrance. For example, it can be used for controlling the entrance and exit of a parking lot. However, for convenience of explanation, it is assumed that the access control system is built on a common porch, and the description will be continued.

Hereinafter, the configuration and operation of a beacon-based access control system according to some embodiments of the present invention will be described in detail.

2 is a configuration diagram of a beacon-based access control system according to the first embodiment of the present invention.

Referring to FIG. 2, the access control system may be configured to include a lobby phone 100, a user terminal 200, and a server 300. However, it should be understood that the present invention is not limited to the above-described embodiments, and that various changes and modifications may be made without departing from the scope of the present invention. In addition, each of the components of the beacon-based access control system shown in FIG. 2 shows functional elements that are functionally distinguished. It is noted that at least one component may be implemented as being integrated with each other in an actual physical environment do. Hereinafter, each component of the access control system will be described.

In the access control system according to the first embodiment, the lobby phone 100 is installed in a common porch and controls the opening and closing operations of the target door, and simultaneously transmits a Bluetooth-based beacon message periodically or aperiodically to be. More precisely, the beacon device mounted on the lobby phone 100 transmits a beacon message and broadcasts a beacon message of a bluetooth low energy (BLE) method. The configuration and operation of the lobby phone 100 will be described later with reference to Fig.

In the access control system according to the first embodiment, the user terminal 200 is a terminal carried by a user accessing through a target door. The user terminal 200 transmits a response message to the server 300 in response to receiving the beacon message. If the beacon message based on Bluetooth can be received, the user terminal 200 may be implemented as any device such as a wearable device such as a smart phone, a tablet PC, or a smart watch. In particular, FIG. 2 illustrates an example in which a plurality of users 200a to 200n are present by having a plurality of users 200, respectively.

In the access control system according to the first embodiment, the server 300 is a computing device that performs authorization verification for a user in response to the reception of the response message, and determines whether the target door is opened or closed. The computing device may be, but is not limited to, a notebook, a desktop, a laptop, and the like, and may include all kinds of devices having computing means and communication means. The configuration and operation of the server 300 will be described later with reference to FIG. 15 later.

In FIG. 2, although the server 300 is illustrated as a single computing device, it may be implemented as a cloud system including a plurality of computing devices according to the size of the system.

In the access control system according to the first embodiment, the lobby phone 100 and the server 300 can communicate, for example, via an in-building network. However, FIG. 2 illustrates an example of the present invention, and the scope of the present invention is not limited thereto.

In the access control system, the user terminal 200 and the server 300 can communicate via a network. The network is usually implemented in a wireless network such as a mobile radio communication network, a Wibro (Wireless Broadband Internet), or the like, but the scope of the present invention is not limited thereto.

The beacon-based access control system according to the first embodiment of the present invention has been described with reference to FIG. Next, the operation of the access control system according to the first embodiment will be described with reference to FIG.

3 is a flowchart illustrating an operation procedure of the access control system according to the embodiment of the present invention.

Referring to FIG. 3, in step S100, the lobby phone 100 transmits a beacon message. For example, the lobby phone 100 broadcasts a beacon message periodically or aperiodically.

The beacon message includes identification information (hereinafter referred to as " first identification information ") of the target door. The first identification information is used to identify a target door to be controlled. In addition, the first identification information is used to verify whether or not the user has an access right to the target door. This is because the user's access right can be set differently for each target door.

The first identification information may be defined by, for example, the ID of the target door, the position of the target door, and the like, but is not limited to the example in which the first identification information is listed. If the target door can be identified, the first identification information may be any information.

According to an embodiment of the present invention, the first identification information may be recorded in the proximity UUID field 51 of the beacon message 50, as shown in FIG. FIG. 4 shows the format of a standard beacon message, which will be apparent to those skilled in the art, and a description thereof will be omitted.

Meanwhile, according to the embodiment of the present invention, the transmission distance of the beacon message can be set differently according to the time zone. For example, the transmission distance of a beacon message may be set to a relatively long distance in a day time zone, and a relatively short distance in a night time zone. This can be understood as considering that the night time zone is generally vulnerable to security. In this embodiment, the setting of the sending distance may be performed by the server 300 or the lobby phone 100. [ For example, the server 300 can adjust the transmission distance of the beacon message by time zone. Alternatively, the transmission distance information of the beacon message may be preset in the lobby phone 100 according to the time zone, and the lobby phone 100 may adjust the transmission distance of the beacon message according to the set information.

Referring back to Fig. 3, in step S110, in response to receiving the beacon message, the user terminal 200 transmits a response message to the server 300. [ More specifically, the dedicated application (app) mounted in advance in the user terminal 200 transmits the response message to the server 300 without user intervention.

According to the embodiment of the present invention, the user terminal 200 transmits the response message to the server 300, not to the lobby phone 100. [ That is, the lobby phone 100 only broadcasts a beacon message, and does not receive a response message from the user terminal 200. Therefore, the Bluetooth pairing process between the user terminal 200 and the lobby phone 100 does not need to be performed, and restrictions on the number of pairings do not apply to the present embodiment. Accordingly, the access control system according to the embodiment of the present invention can be constructed without restrictions on the environment in which a plurality of users exist.

The response message includes first identification information on the target door and identification information on the user (hereinafter referred to as " second identification information "). The second identification information may be, for example, a user ID, an ID of a user terminal, a telephone number of a user terminal, and the like, but is not limited to the example in which the second identification information is listed. If the user can be identified, any information may be used as the second identification information.

5, the response message 70 includes not only the first identification information 75 and the second identification information 71 but also the signal of the beacon message measured at the user terminal 200 The intensity information 73 may be further included. The signal strength information 73 may be, for example, a received signal strength indicator (RSSI), but may be other information. According to the embodiment, the response message 70 may include distance information between the user and the lobby phone 100 calculated using the signal strength information 73 and / or the signal strength of the beacon message. Further, identification information such as a complex, a corridor, a lake, etc. in which the user lives may be further included.

Referring again to FIG. 3, in step S120, the server 300 verifies the access right of the user possessing the user terminal 200. [ For example, the server 300 may determine whether the user who has transmitted the response message is authorized to access the target door by using the authority information of the previously registered user. In more detail, the server 300 identifies the target door through the first identification information included in the response message, and identifies the user through the second identification information included in the response message. In addition, the server 300 determines whether or not the user is authorized to access the target door using the previously registered authority information of the corresponding user.

For reference, the user can register the privilege information in advance through the dedicated app installed in the user terminal 200 (e.g., registered as a resident of the household), and then an appropriate authentication procedure can be performed.

In step S130, the server 300 determines whether the target door is open or closed using the verification result of step S120.

In step S140, the server 300 transmits a door open message to the lobby phone 100 in response to the determination of opening the target door. However, according to the embodiment, when the server 300 can directly control the target door, the server 300 may directly transmit a control message for opening the door to the target door. Also, when there is a separate device for controlling the target door, the server 300 can transmit the door open message to the separate device. Hereinafter, it will be assumed that the lobby phone 100 performs a function of controlling the target door.

In step S150, the target door is opened. For example, the target door may be opened as the lobby phone 100 delivers the door open signal to the target door.

The configuration and operation of the beacon-based access control system according to the first embodiment of the present invention have been described with reference to Figs. 2 to 5 above. Next, a beacon-based access control system according to a second embodiment of the present invention will be described with reference to FIG.

6 is a configuration diagram of a beacon-based access control system according to a second embodiment of the present invention.

Referring to FIG. 6, the access control system according to the second embodiment may be further configured to include a generation phone 400. In particular, FIG. 6 illustrates an example in which a plurality of generation phones 400a to 400b are provided in each of a plurality of generations.

In the access control system according to the second embodiment, the generation phone 400 can control a door lock installed in each household door. In addition, the household phone 400 can communicate with the server 300 and / or the lobby phone 100 via the building network.

In the present embodiment, when the access right of the user is verified, the server 300 inquires the generation information of the user stored in advance, and transmits a door lock release message to the household phone 400 in which the user lives using the inquired generation information can do. For example, in response to the opening determination of the target door installed in the common porch, the server 300 may send a door lock release message to the household phone where the user resides. According to the present embodiment, the user may not perform any action to open the door until arriving at the household in which he or she lives. Therefore, the convenience of the user can be further increased.

Also, according to the embodiment of the present invention, the time at which the server 300 transmits the door lock release message may be changed using the distance from the common entrance to the household where the user lives. For example, the greater the distance from the common entrance to the household, the later the door lock release message may be transmitted. This is to prevent the household door from being opened before the user approaches the household in which he lives. According to the present embodiment, the opening time of the generation door can be minimized.

The beacon-based access control system according to the second embodiment of the present invention has been described with reference to FIG. Hereinafter, a beacon-based access control system according to a third embodiment of the present invention will be described with reference to FIG.

7 is a configuration diagram of a beacon-based access control system according to a third embodiment of the present invention. In particular, FIG. 7 shows an example in which the access control system is constructed in a large facility having a common entrance for each complex.

Referring to FIG. 7, the access control system according to the third embodiment may be further configured to include gateways 510a to 510n for each complex. Further, for each complex, the subnetworks 500a to 500n can be configured. Each of the gateways 510a to 510n can relay the communication between the server 300 and the subnetworks 500a to 500n of the corresponding complex.

In this embodiment, when the server 300 transmits a door open message to the lobby phone 100a installed adjacent to the target door, the door open message is transmitted to the lobby phone 100a via the gateway 510a of the sub network 500a ). ≪ / RTI > The operation of the access control system according to the third embodiment is similar to that of the access control system according to the first embodiment, and a further explanation will be omitted.

The access control system according to the third embodiment of the present invention has been described with reference to FIG. Hereinafter, some embodiments of the present invention that can be performed together with the access control operation in the access control system described above will be described with reference to Figs. 8 to 13. Fig.

8 and 9 illustrate a method of providing a notification service to an authorized user according to an embodiment of the present invention.

According to the embodiment of the present invention, a notification service can be provided through the lobby phone 100 to a user whose access is authorized through authority verification (hereinafter referred to as " authorized user "). Specifically, the server 300 may inquire the notification message related to the authorization using the second identification information on the licensee, and provide the inquired notification message through the lobby phone.

8, when an authorized person enters and leaves a household through a target door installed on a common porch, for example, notification messages 151 and 153 regarding unrecorded parcels And may be provided through the lobby phone 100. [ The notification message may be displayed on the lobby phone 100 like the message 151 and may be provided as a voice message on the lobby phone 100, In the example of FIG. 8, a courier receipt message is shown as an example of a notification message, but this is merely an example for convenience of understanding, and the access control system may vary depending on the place where the access control system is installed and / or the user.

According to the embodiment, the type of the notification message, the provision of the notification message, and the like may be configured to be set by the user through a dedicated application installed in the user terminal 200. In such a case, a user can provide a customized notification service for each user by setting a kind of a message to receive a notification through a dedicated application.

Meanwhile, according to the embodiment of the present invention, the notification service may operate so as to be provided only under certain conditions in consideration of privacy of an authorized user. For example, the notification service may be provided only when there is no other user entering or leaving the common porch. In such a case, the server 300 may determine whether or not the number of persons existing in the periphery of the common porch is less than or equal to a preset threshold value, and determine whether to provide the inquired notification message using the result of the determination.

In this embodiment, the number of persons present in the vicinity of the common entrance can be obtained through a surveillance image of CCTV (610, closed circuit television) installed adjacent to the common entrance as shown in FIG. More precisely, the number of people located around the common porch can be counted through video analytics on the surveillance image. Alternatively, the number of persons may be determined using the number of different second identification information received during a predetermined time. However, since the number of different second identification information does not include a person having a user terminal that has not responded to the beacon message, some inaccurate information may be derived.

According to the embodiment of the present invention, when another user is present around the common porch, the manner in which the notification service is provided may be changed. For example, if another user is present around the common porch, the notification message may be provided to the user terminal 200 possessed by the user in the form of a short messaging service (SMS), an application push notification, or the like.

8 and 9, a notification service providing method according to an embodiment of the present invention has been described. According to the above description, since various notification messages for the user such as unredeemed courier information can be provided through the lobby phone 100, convenience for the user can be improved. Hereinafter, with reference to FIG. 10, a control method of a target door in consideration of a moving direction of a user according to an embodiment of the present invention will be described.

10 is a view for explaining a method of controlling a target door accurately in consideration of a moving direction of a user according to an embodiment of the present invention.

According to an embodiment of the present invention, as shown in Fig. 10, a plurality of beacons 100, 630, and 650 are installed at different positions adjacent to the target door. In addition, a beacon message is broadcast in each of the beacon apparatuses 100, 630, and 650. At this time, the beacon message includes identification information of each beacon device (100, 630, 650).

In response to receiving the beacon message, the user terminal 200 transmits a response message including the signal strength information of each beacon message and the identification information of the beacons 100, 630, and 650 to the server 300.

In response to receiving the response message, the server 300 determines the direction of movement of the user by using signal strength information of the beacon message transmitted from each of the plurality of beacons 100, 630, and 650. More precisely, the server 300 determines the moving direction of the user by using the degree of change in the signal strength information of each beacon message and the position of the beacons 100, 630, and 650 identified through the identification information. At this time, the location of the beacons 100, 630, and 650 may be preset information. A method of determining a direction of movement by receiving a plurality of signals will be apparent to those skilled in the art, and a description thereof will be omitted.

In the present embodiment, the server 300 controls the target door using the determined moving direction of the user. For example, the server 300 may not open the target door if the direction of movement is not toward the target door, even if the user is authorized to access the server. Alternatively, the server 300 may transmit the door open message to the lobby phone 100 at a time point when the movement direction of the authorized person is accurately directed to the target door. According to the present embodiment, since the opening and closing timings of the target door can be determined more accurately, the accuracy of access control can be improved.

Meanwhile, according to another embodiment of the present invention, the server 300 may control the target door by determining the moving speed of the user. Specifically, the server 300 may determine the moving speed of the user using the first signal strength information received at the first time point and the second signal strength information received at the second time point from the user terminal 200. [ In addition, the server 300 may determine the opening time or the closing time of the target door by determining the moving speed. For example, if an author quickly approaches the target door, the server 300 may provide a secure access service by quickly opening the target door. As another example, the server 300 may minimize the opening time of the target door by allowing the target door to open after a certain point of time, if the applicator is slowly approaching the target door. Thus, the safety of the facility in which the access system is built can be improved.

The method of controlling the target door using the moving direction and / or the moving speed of the user has been described with reference to FIG. Hereinafter, a method for controlling a target door using a user type according to an embodiment of the present invention will be described with reference to FIG.

11 is a flow diagram of a method for determining an open time of a target door using a type of user in accordance with an embodiment of the present invention.

Referring to FIG. 11, in step S210, the server 300 determines the type information of the user who has the user terminal 200. FIG. At this time, the type information can be defined using various factors such as, for example, demographic information, presence of a vehicle, presence or absence of a wheelchair, and the like, depending on the embodiment.

In one embodiment, the type information of the user may be determined using the second identification information of the received user. More specifically, the user registers his / her user type information through a dedicated application installed in the user terminal 200, and the server 300 inquires the type information of the previously registered user using the second identification information The type information of the user can be obtained.

In one embodiment, the type information of the user may be determined using image analysis information for the surveillance image obtained from the CCTV. At this time, the CCTV means CCTV installed adjacent to the target door. For example, the server 300 can acquire demographic information of a user through image analysis of the surveillance image, and determine the type information of the user using the obtained demographic information.

In step S230, the server 300 determines the opening time of the target door using the type information of the user determined in step S210. For example, if the user is a wheelchair user, the opening time of the target door can be determined to be a relatively long time. As another example, even when the user is an elderly person, the opening time of the target door can be determined to be a relatively long time. The user may take a relatively long time to complete access through the target door.

In step S250, the server 300 controls the target door to be opened during the open time determined in step S230.

The method of determining the opening time of the target door using the type information of the user has been described with reference to FIG. According to the above description, the opening time of the target door may be changed according to the type of the user. For example, in the case of a type of user who takes a long time to complete access (e.g., an elderly person, a wheelchair user, etc.), the safety of the user can be secured by keeping the open time of the target door long. For another example, in the case of a type of user that takes less time to complete access (e.g., 20 males, etc.), the security of the facility may be improved by keeping the open time of the target door short.

Meanwhile, according to the embodiment of the present invention, when a plurality of target doors are installed around the lobby phone, the target door to be controlled can be identified using the type information of the user. For example, when a common entrance door and a parking entrance are installed in the vicinity of a lobby phone, the type of the user is determined according to whether the vehicle is boarded. In the case of a user who boarded the vehicle, the entrance of the parking lot can be identified as the control object. The presence or absence of the vehicle can be determined through, for example, monitoring video analysis of the CCTV.

Hereinafter, a method of controlling the target door using the face recognition result according to the embodiment of the present invention will be described with reference to FIG.

12 is a flowchart of a method for determining whether a target door is opened or closed by further using a face recognition result of a user according to an embodiment of the present invention.

According to the embodiment of the present invention, additional verification as to whether the user possessing the user terminal 200 corresponds to the user indicated by the second identification information included in the response message can be performed through face recognition. Alternatively, even if the user does not have the user terminal 200, the determination as to whether or not the user corresponds to an authorized person with access rights can be performed through face recognition. Hereinafter, a process of performing the face recognition will be briefly described.

Referring to FIG. 12, in step S310, the server 300 obtains image information about the user. For example, surveillance video information for a user can be obtained via CCTV installed adjacent to the target door. As another example, image information about a user can be obtained through a camera of a lobby phone installed adjacent to the target door.

In step S330, the server 300 performs face recognition for the user. For example, face recognition can be performed through matching between the stored face DB and the analyzed face image through the surveillance image.

In step S350, the face recognition result is further used to determine whether the target door is opened or closed. For example, if the user indicated by the face recognition result (i.e., the owner of the current user terminal 200) is different from the original owner of the user terminal 200, the server 300 controls the target door to be kept closed can do. As another example, if the user is judged to be a face recognition result access right even when the user does not possess the user terminal 200, the server 300 can control the target door to be opened.

According to the above-described embodiment, access to unauthorized persons is restricted through face recognition when the user terminal 200 is seized, so that the security of the facility in which the access control system is built can be improved. Also, even if the user terminal 200 is not carried, the target door can be automatically opened through face recognition, and user convenience can be improved.

Hereinafter, with reference to FIG. 13, a method for determining whether to open or close the target door in consideration of unauthorized persons around the target door will be described. In particular, FIG. 13 shows an example where the applicator 710 and the non-applicant 730 coexist in the vicinity of the common porch.

Referring to FIG. 13, in this embodiment, the server 300 determines whether or not an unauthorized person 730 having no access right exists around the target door, and determines whether the target door is open or closed using the result of the determination .

In one embodiment, the presence of the unauthorized person can be determined using the result of comparison between the number of different second identification information received for a predetermined time and the number of persons present around the target door. For example, in the example shown in Fig. 13, the number of different second identification information is " 1 " the identification information received from the terminal of the author 710, and the number of persons around the target door is &Quot;, it can be determined that one unauthorized person 730 exists.

The number of persons present in the vicinity of the target door may be determined using the monitoring image obtained through the CCTV 610 installed adjacent to the target door, as shown in FIG. Alternatively, it may be determined using a proximity sensor installed adjacent to the target door. The method of counting the number of persons from the surveillance image and / or the method of determining the number of persons by using the proximity sensor are already known to those skilled in the art, and the description thereof will be omitted.

In one embodiment, the presence or absence of an unauthorized person may be determined using a face recognition result. For example, face recognition is performed using the surveillance image obtained through the CCTV 610 installed adjacent to the target door, and when there is a user 730 that can not recognize the face, it is determined that there is an unauthorized person .

In this embodiment, the server 300 may decide to keep the target door closed in response to a determination that an unauthorized person is present. Accordingly, access by unauthorized persons coming along the licensee can be restricted, and the security of the facility can be improved.

Meanwhile, according to the embodiment of the present invention, the server 300 can operate to open the target door in response to the separate access request information received from the user terminal 200, even in the presence of unauthorized persons.

At this time, the access request information may be arbitrary information that is automatically transmitted to the server 300 as the user terminal 200 recognizes the designated user behavior. The predetermined user action may be variously defined, for example, by a screen click of the user terminal 200, an action of shaking the user terminal 200 up / down, left / right, etc., It may be designated as an action.

For reference, a user may be configured to register a user action that triggers a transmission operation of the access request information by using a dedicated application installed in the user terminal 200. [ According to the present embodiment, when there is a user who smiles a user terminal around a common porch, a friend of an authorized person, a courier article, or the like, the authorized person performs only the most convenient behavior set by himself / herself, Open. Accordingly, user convenience and facility security can be secured at the same time.
