Description

[Technical Field]

[0001] The present invention relates to a building access control system that combines facial recognition and smart locks and flexibly issues PIN numbers to be used with smart locks, thereby improving the convenience of access control in buildings and reducing the risks associated with the use of conventional keys. [Background technology]

[0002] Traditionally, front doors in detached houses, common area doors in apartment complexes and other multi-family housing, and front doors to private rooms have typically been locked and unlocked using physical keys. However, the use of physical keys carries the risk of keys being lost, duplicated, or stolen, and with the increase in dual-income households, there is growing concern about giving keys to children. As a result, smart lock (smart key) systems, which use PIN numbers or cards to lock and unlock doors, are increasingly being adopted as an alternative to physical keys.

[0003] In recent years, the spread of remote work has increased the risk of information leaks and unauthorized access to PCs, and traditional methods using physical keys have made it difficult to address these issues (entry and exit cannot be adequately controlled, making it impossible to know who has entered).Even with smart locks, while strict entry and exit management is carried out in offices and other buildings, it is difficult to say that they are adequately addressing these issues in other facilities such as apartment complexes.

[0004] Known systems for managing entry and exit at facilities include one that uses contactless IC cards and has each person read their contactless IC card with a reading device when entering or leaving a conference room (Patent Document 1), one that uses a smartphone to receive an entry permission signal based on reservation information and lock or unlock the door (Patent Document 2), and one that uses a human detection unit and an open / close detection unit to monitor the presence of people around the door and the open / close status of the door, and manages people's entry and exit (Patent Document 3). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-323695 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-204233 [Patent Document 3] Japanese Patent Publication No. 2022-161755 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the system of Patent Document 1 requires each person to have an IC card, the system of Patent Document 2 requires reservation information to enter and is therefore not suitable for use in apartment buildings, and the system of Patent Document 3 is not a system that can distinguish between residents and non-residents, so it is difficult to say that either system is convenient for residents or managers.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a building access control system that combines facial recognition and smart locks and flexibly issues PIN numbers to be used with smart locks, thereby improving the convenience of access control in buildings and reducing the risks associated with the use of conventional keys. [Means for solving the problem]

[0008] In order to solve the above problems, the building entry / exit management system according to the present invention comprises: In a building having a common area and a private area, a face authentication unit that can unlock the common door by face authentication is installed near the common door used as an entrance / exit for the common area, and an electronic lock device is installed on the private door installed at the entrance / exit of each room in the private area, a management device, the management device being connected via a network between the face authentication unit, the electronic lock devices in the rooms, and an administrator terminal, and also being connectable via a network to a mobile terminal of the user; The management device includes a user registration reception unit including facial image data of users, a database unit, a personal identification number issuing unit that issues a personal identification number for locking and unlocking an electronic lock device of a private door for each room, a face authentication determination unit that determines a face image from the face authentication unit, and an unlock command unit that unlocks a common door based on the determination by the face authentication determination unit, The database unit is synchronized with the electronic lock device of each room in the building, and a different password number table corresponding to a calendar is registered for each room in the building, and the password number table is assigned a different password number for each calendar date in accordance with the calendar date, The first feature of the password number issuing unit is that, upon request from the terminal of a registered user, it issues a PIN number assigned on the day of occupancy from the password number table for the room the user will be occupying, which is one of the calendar-based password number tables registered in the database unit for each room in the building, as a PIN number to unlock the electronic lock device on the private door of the room the user will be occupying.

[0009] The building entry / exit management system according to the present invention comprises: A second feature of the system is that after the user moves in, upon request from the registered user's terminal, the password number issuing unit selects the password number assigned on the requested change date from the password number table for the room the user will be occupying, which is one of the calendar-based password number tables registered for each room in the building in the database unit, and issues a new password to unlock the electronic lock device on the private door of the room the user will be occupying, in place of the password before the change.

[0010] The building entry / exit management system according to the present invention comprises: A list of reissue PIN numbers is registered in the database unit with a priority order for each calendar date in a calendar-based PIN number table registered for each room in the building, A third feature is that the management device is equipped with a PIN reissue unit, which, upon request from a terminal of a registered user, replaces the PIN from a list of reissue PINs assigned on the requested date with the PIN before reissue, and reissues the reissue PIN in accordance with priority as the PIN for unlocking the electronic lock device on the private door of the room in which the user resides.

[0011] The building entry / exit management system according to the present invention comprises: A fourth feature is that the building is any one selected from an apartment building, an office building, and a commercial building.

[0012] The building entry / exit management system according to the present invention comprises: the user registration receiving unit is capable of receiving face image data of a person other than the user, transmitted from a terminal of the registered user, and registering the face image data of a person other than the user as a guest in the database unit; A fifth feature is that in the common area, if the facial image data from the facial authentication unit matches the facial image data registered as a guest, the unlock command unit unlocks the common door based on the judgment by the facial authentication judgment unit. [Effects of the Invention]

[0013] As described above, the building entry / exit management system of the present invention combines facial recognition for the building's shared doors with electronic locking devices for the private doors in the private areas, and also incorporates ingenuity in issuing PIN numbers for the electronic locking devices for the private doors, thereby enabling users to manage entry and exit to the building and making it easier for management companies to manage entry and exit.

[0014] Furthermore, by eliminating the use of physical keys, the access control system of the present invention eliminates the risks of keys being lost, duplicated, or stolen, as well as the anxiety of letting children have keys, and further reduces the risks of information leaks and unauthorized access to PCs.

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described with reference to the drawings. Figure 1 shows an example of the configuration of an entrance / exit system according to the present invention, and Figure 2 shows a floor plan of a building.

[0017] 1, the building entry / exit management system S is a system for managing entry / exit to a building 1 of an apartment building, for example, a rental apartment, and includes a management device (management server) 10. Note that the building 1 may also be an office building housing multiple business establishments, as will be described later.

[0018] Building 1 has common areas and private areas, and as shown in Figure 2, a passage door 3 (hereinafter referred to as common door 3) is provided at the entrance to the common area, entrance 2. Outside entrance 2, near common door 3, a face authentication unit 4 is provided that authenticates the faces of people (residents, visitors, contractors, etc.). Common door 3 is opened and closed by a drive device (not shown) after receiving face authentication from face authentication unit 4. The face authentication unit 4 corresponds to, for example, a face authentication terminal with a camera.

[0019] Each floor of the building 1 is provided with a private room 5. An entrance door 6 (hereinafter referred to as a private door 6) is provided at the entrance (entrance) of each room 5, and an electronic locking device 7 is attached to the private door 6 of each room 5. The electronic locking device 7 of each room 5 can be unlocked with a dedicated PIN number. The entrance 2 and floors above can be accessed by elevator 8 and stairs (not shown).

[0020] The management device 10 is connected to a face authentication unit 4 provided at the entrance 2 of the building 1, an electronic lock device 7 attached to a private door 6 of each room 5, and an administrator terminal 20 via a network 40. The management device 10 is also connectable via the network 40 to a mobile terminal 30 of a user who is a resident of each room 5.

[0021] As shown in Figure 3(A), the management device 10 has a communication processing unit 11, a user registration reception unit 12, a database unit 13, a PIN issuing unit 14, a PIN reissuing unit 15, a face authentication judgment unit 16, an unlocking command unit 17 for the shared door 3, and a control processing unit 18.

[0022] The communication processing unit 11 communicates with the face authentication unit 4 and the electronic lock device 7, and also with the administrator terminal 20 and the mobile terminal 30 of the user.

[0023] The user registration reception unit 12 receives user registration from the mobile terminal 30 of the user who uses the management system S (see FIG. 4), and in this embodiment, the user corresponds to the occupant of the building 1. When registering, the user registers his / her facial image data F (see FIG. 5).

[0024] The user's face image data F is image data obtained by photographing the user's face from the front, and is registered as image data that can be used for facial recognition, and can authenticate whether the user is the real person based on the positions of feature points such as the eyes, nose, and mouth, and the position and size of the facial area. The user's face image data is transmitted from the user's mobile terminal 30 to the management device 10.

[0025] As shown in FIG. 3(B), the database unit 13 includes a building information DB, a personal identification number information DB, and a user information DB.

[0026] The building information DB stores building information about multiple buildings 1 (facility A to facility D are shown in Fig. 1) managed by the administrator. The building information includes, for each building 1, information about the building name, address, number of floors, shared doors at the entrance, face authentication unit, door opening / closing device, private doors for each room, electronic locking device, etc.

[0027] The PIN DB has registered therein a different calendar-based PIN table (hereinafter referred to as a calendar-based PIN table) for each room 5 in each building 1. In the calendar-based PIN table for each room 5, a different PIN is pre-assigned and registered for each calendar year, month, and day for a certain period (for example, 20 years) (365 different PIN numbers are assigned for 20 years (366 in leap years)). The PIN consists of several digits (for example, 4 to 8 digits).

[0028] Figures 6 and 7 show examples of displaying a calendar-compatible PIN table. Figure 9 shows an example (2023) of the calendar-compatible PIN table T registered in the PIN DB, with some parts omitted. As will be described later, in each PIN registration field of the calendar-compatible PIN table T, a list of multiple PINs that can be reissued per day is registered and linked via a pull-down menu. The PIN DB stores 20 years' worth of tables for each room 5. PINs can also be composed of a combination of numbers, letters, and symbols.

[0029] The calendar-based PIN table registered in the PIN DB is synchronized with the electronic lock device 7 for each room 5, and the electronic lock device 7 stores all the PIN numbers corresponding to the calendar-based PIN table registered in the PIN DB for the corresponding room 5.

[0030] The user information DB registers user information about users who reside in building 1. The user information includes personal information such as a user ID, password, name, resident name (nickname), building name, room number, address, email address, telephone number, date of birth, facial image data, move-in date, and move-out date. Of the user information, the password, resident name (nickname), and facial image data are registered from the user's mobile terminal 30. Other information is registered from the administrator terminal 20.

[0031] The facial image data registered in the database unit 13 is not limited to that of the user himself / herself; the user can select to register multiple facial image data of guests other than the user (people whom the user allows to enter the room 5, such as the user's family members or friends) sent from the user's mobile terminal 30.

[0032] The PIN issuing unit 14 issues a PIN assigned to the occupancy date on the calendar from a calendar-compatible PIN table for each room 5 as a dedicated PIN for unlocking the electronic lock device 7 attached to the dedicated door 6 for each room 5.

[0033] As will be described later, a different calendar-based PIN table is pre-registered in database 13 for each room 5. In response to an issuance request from mobile terminal 30 of a user who is the occupant of room 5, PIN issuing unit 14 issues the PIN assigned to the occupancy date of the relevant room 5 from the calendar-based PIN table for each room 5 stored in database 13 as a dedicated PIN for unlocking electronic lock device 7 of the relevant room 5.

[0034] 6, when a registered user calls up the PIN registration screen G3 on the mobile terminal 30 on the move-in date (September 14, 2023), a calendar display section c and a PIN display section d are displayed on the PIN registration screen G3. Furthermore, a mark m is displayed on the move-in date (September 14, 2023) in the calendar display section c, and the PIN pc1 (919173) assigned on the same day (September 14, 2023) is displayed in the display field d1 of the PIN display section d.

[0035] Therefore, when the user presses the registration button e on the PIN registration screen G3, the PIN pc1 (919173) assigned to the move-in date (September 14, 2023) is registered in the database unit 13 and issued to the user.

[0036] The PIN number pc1 (919173) issued to the user is sent to the user's mobile terminal 30. When the user inputs the issued PIN number pc1 (919173) into the electronic lock device 7 of the corresponding room 5 on the same day as the issuance date (moving in date), the dedicated PIN number pc1 (919173) is saved in the locking / unlocking operation program in the electronic lock device 7. If the user is unable to input the number into the electronic lock device 7 on the issuance date, the issued PIN number pc1 (919173) becomes invalid, and the user must issue and register a new PIN number again the following day or later.

[0037] If the user wishes to change the PIN issued on the move-in date on a date after the move-in date, the PIN issuing unit 14 will issue the PIN assigned on the requested date as the changed PIN from the calendar-based PIN table registered for each room 5 in the database unit 13 in accordance with the issuance request from the user's mobile terminal 30.

[0038] For example, referring to Figure 7, if a user wishes to change the PIN number pc1 (919173) issued on the move-in date (September 14, 2023) on a date after the move-in date (September 19, 2023), when the user calls up the PIN number registration screen G3 on the user's mobile terminal 30 on the change date, a mark m will be displayed on the change date (September 19, 2023) in the calendar display section c, and the PIN number pc2 (763685) assigned on the change date will be displayed in the display field d1 of the PIN number display section d.

[0039] Therefore, when the user presses the registration button e on the PIN registration screen G3, the PIN pc2 (763685) assigned on the change date (September 19, 2023) is registered in the database unit 13 and issued to the user. The previous PIN pc1 (919173) issued on the move-in date becomes invalid.

[0040] The changed PIN number pc2 (763685) is sent from the password issuing unit 14 to the user's mobile terminal 30. When the user inputs the changed PIN number into the electronic locking device 7 of the room 5 that the user occupies on the day of the change and operates it, the changed PIN number pc2 (763685) is saved in the locking / unlocking operation program in the electronic locking device 7.

[0041] The PIN reissue unit 15 issues PINs that can be reissued in a day in order of priority in response to a reissue request from the user's mobile terminal 30, and reissues different PINs multiple times in order of priority from a reissue PIN list assigned to each calendar date in the calendar-based PIN table registered in the database 13 for each room 5.

[0042] 8, on the date when the user requests reissue (September 19, 2023), when the user presses the pull-down button f in the PIN display section d on the PIN registration screen G3 of the user's mobile terminal 30, a reissue list selection field g is displayed. When the user selects "First reissue" in the reissue list selection field g, the first PIN to be reissued is displayed in the PIN display field d.

[0043] Therefore, when the user presses the registration button e on the PIN registration screen G3, the first reissued PIN is registered in the database unit 13 and issued to the user. In the example of Fig. 8, a PIN can be reissued up to 10 times per day.

[0044] The PIN reissued by the PIN reissue unit 15 is sent to the user's mobile terminal 30. When the user enters the reissued PIN into the electronic lock device 7 of the room 5 that the user occupies on the day of reissue and performs the unlocking operation, the changed PIN is saved in the locking / unlocking operation program in the electronic lock device 7.

[0045] For example, if a user wants to invite different guests into room 5 at different times of the day, the user can reissue the PIN and enter it into electronic lock device 7 multiple times in sequence for different times of the day, and provide the reissued PIN to the guests sequentially during the specified time periods, allowing the guests to smoothly enter room 5 using the provided PIN during the specified time periods.

[0046] The face authentication determination unit 16 determines whether the user is permitted to enter the entrance 2 or whether the user is a guest, based on the face image data transmitted from the face authentication unit 4 outside the entrance 2 and the face image data registered in the database 13.

[0047] The unlock command unit 17 unlocks the common door 3 based on the determination by the face authentication determination unit 16. That is, if the face image data sent from the face authentication unit 4 matches the face image data registered in the database unit 13, it sends a command to a drive device (not shown) to unlock the common door 3. Figure 10 shows the face authentication determination and unlocking operation at the entrance 2. If the face image data do not match, the common door 3 remains locked.

[0048] The unlock command unit 17 sends a command to a drive device (not shown) to unlock the common door 3 in response to a request command from the user's mobile terminal 30 or a request command from the administrator's terminal 20. The drive device is equipped with a motor, unlocks the common door 3 in response to the command, and after several seconds have passed since unlocking, moves on to the locking operation. In addition, in preparation for moving companies and the like, the drive device keeps the door unlocked for a certain period of time in response to a command from the administrator's terminal 20.

[0049] The control processing unit 18 executes and processes the communication processing unit 11, the user registration reception unit 12, the PIN issuing unit 14, the PIN reissuing unit 15, the face authentication determination unit 16, and the unlocking command unit 17 based on requests or commands from the user's mobile terminal 30 or the administrator terminal 20.

[0050] Next, a method for managing entry and exit to the building 1 using this management system S will be described below.

[0051] First, the administrator registers user information as a resident of building 1 based on a rental contract in database 13 of management device 10 from administrator terminal 20. The user information to be registered includes a user ID, password (initial), name, building name, room number, address, email address, telephone number, date of birth, contract period, etc.

[0052] Next, the administrator sends a user registration guide email containing a user ID and an initial password from the administrator terminal 20 to the mobile terminal 30 of a prospective tenant (hereinafter referred to as a user) of building 1. The user can then call up a login screen from the URL displayed in the guide email sent to the mobile terminal 30 and log in to the login screen with the user ID and password to complete user registration. After logging in, the user can change the initial password on the password change screen.

[0053] Next, the user registers the user by entering the resident's name (nickname is acceptable) in input field a of the user registration screen G1 (see Figure 4) from the mobile terminal 30, and then selects and registers the facial image data F to be used for facial authentication in input field b of the facial photo registration screen G2 (see Figure 5), and when they are sent, the user registration acceptance unit 12 accepts the user registration, and the user registration is completed.

[0054] The user can register facial image data of guests (there is an upper limit to the number of guests) authenticated by the user on the guest registration screen from the mobile terminal 30. The user registration information (including the facial images of the guests) is registered in the user information DB of the database 13 by the user registration reception unit 12.

[0055] Once the user has registered, the user can obtain, from the user's mobile terminal 30, the personal identification number for the private door 6 of the room 5 (for example, room 201) in which the user resides.

[0056] When the user displays the PIN registration screen G3 (see Figure 6) on the mobile terminal 30 on the move-in date (September 14, 2023), the calendar display section c of the PIN registration screen G3 will display a calendar k for the month in which the user will move in, and a mark m will be displayed on the move-in date (September 14, 2023) on the calendar k, and the PIN number pc1 assigned to the move-in date will be displayed in the display field d1 of the PIN display section d.

[0057] When the user presses the registration button e on the screen of the mobile terminal 30, the PIN number pc1 displayed on the PIN number display section d is registered as the PIN number for the private door 6 of the room 5 (No. 201) in which the user resides and is issued to the user.

[0058] Referring to Figure 10, on the day user Y moves in, when he or she brings his or her face close to the facial authentication unit 4 in front of the entrance 2 of the building 1, the facial authentication unit 4 acquires facial image data, and the facial authentication determination unit 16 of the management device 10 compares the facial image data sent from the facial authentication unit 4 with the facial image data registered in the database 13 to determine whether or not the user is permitted to enter the entrance 2.

[0059] When the face authentication determination unit 16 of the management device 10 determines that the user is authorized to enter the entrance 2, the unlock command unit 17 unlocks the common door 3, allowing user Y to enter the entrance 2.

[0060] Next, User Y enters Entrance 2, moves to another floor, and unlocks Private Door 6 in front of Room 5 (No. 201) where User Y will be staying, as shown in Figure 11. Using the above procedure, User Y obtains the PIN number pc1 dedicated to the electronic lock device 7 of Private Door 6 on the day of moving in.

[0061] When user Y enters the acquired PIN pc1 into electronic lock device 7, it is synchronized with the calendar-based PIN table registered in database unit 13 and checked against the PIN (on the day of occupancy) stored in electronic lock device 7, and electronic lock device 7 is unlocked and the PIN is stored in electronic lock device 7. This allows user Y to enter room 5 (201).

[0062] According to this embodiment, a user moving into room 5 can obtain the PIN number pc1 of the electronic lock device 8 on the private door 6 of room 5 from the mobile terminal 30 on the day of occupancy, allowing the user to smoothly enter and exit room 5 from the day of occupancy, and also reducing the burden on the management company of managing entry and exit to room 5.

[0063] According to the system of this embodiment, a user can send a facial image of a guest from mobile terminal 30 to management device 10 and register the guest, allowing the user to manage the guest's entry and exit to living room 5. When allowing a guest to enter and exit the room, the user can reissue a PIN multiple times, allowing the user to manage the guest's entry and exit to living room 5 in detail, for example by specifying a time for the guest.

[0064] According to the system of this embodiment, after moving in, the user can easily change the PIN number from a calendar-based PIN number table registered in advance for each room 5, without having to request the management company or go through complicated procedures, thereby greatly improving the convenience of managing entry and exit to rooms 5.

[0065] By adopting the system of this embodiment, it is possible to abolish the use of physical keys, eliminate the risks of keys being lost, duplicated, or stolen, and also alleviate the anxiety of letting children have keys due to the increase in dual-income households.

[0066] The system of this embodiment can minimize the risks of information leaks outside the company and unauthorized access to PCs that arise due to the spread of remote work, and can adequately address these risks even when working remotely in shared housing, etc.

[0067] In this embodiment, the users are assumed to be residents of an apartment building, but the building is not limited to an apartment building. The access control system of the present invention can also be applied to office buildings and commercial buildings where multiple businesses and tenants occupy each room. The users are the managers of the businesses and tenants occupying each room, and employees can be handled by registering face image data as guests. Furthermore, the present invention can also be applied to short-term and long-term stay accommodation facilities, etc. [Industrial Applicability]
