Description

[Technical field]

[0001] The present invention relates to an electronic lock device and a locking / unlocking method. [Background technology]

[0002] Conventionally, there is known an electronic lock system in which an electronic key and an electronic lock communicate with each other to control the locking and unlocking of a door. In the conventional method, the authentication process of an electronic lock attached to a hotel room or a warehouse door is performed by a server device, etc., which is connected to the electronic lock via online or contactless communication.

[0003] For example, in the unlocking control system described in Patent Document 1, a management computer of a management company stores room IDs, contract IDs, valid use periods, and various other data. This unlocking control system includes a card-type key and an unlocking control device installed on the door of the accommodation room. The card key stores the room ID and the valid use period of the accommodation facilities. The unlocking control device stores the room ID and contract ID in a memory unit, and performs authentication processing to verify whether the room ID and contract ID read from the card key match the stored room ID and contract ID, respectively.

[0004] [Patent Document 1] JP 2009-026264 A Summary of the Invention [Problem to be solved by the invention]

[0005] For example, when checking into a hotel or other lodging facility, traditionally, one would receive a room key at the front desk, be given an explanation of the hotel's main facilities (e.g., large public bath, dining areas, evacuation routes, distribution of service coupons at shops, etc.), and then be shown to their room. However, in the case of hotels and other accommodation facilities, there are many hotels where multiple buildings are connected due to expansion, etc., making the route complicated. In addition, the location of the large public bath and dining area can be difficult to understand with just one explanation from the front desk. Furthermore, it can take time for the front desk staff to explain things in detail. In addition, while evacuation routes and other information are often displayed on the door of the room, some guests often do not check it, so it is necessary to devise a way to check it immediately in the event of an emergency. Furthermore, for overseas guests, many hotels only provide information in a few languages ​​such as Japanese, English, and Chinese for information about the hotel and nearby tourist attractions, and the information is sometimes provided on paper. Furthermore, when storing items or documents in a warehouse or the like, as the amount of items stored increases or as storage time passes, the type and location of the items may become unclear.

[0006] The present disclosure has been made in consideration of these circumstances, and aims to provide an electronic lock device, a locking / unlocking method, and an electronic lock system that can reduce the burden on facility managers where electronic lock devices are installed while increasing convenience for users. [Means for solving the problem]

[0007] The present disclosure has been made to solve the above-mentioned problems, and one aspect of the present disclosure provides an electronic lock device including a communication unit that communicates with a mobile terminal device, a memory unit that stores value-added information related to the area in which the electronic lock device is installed, an authentication unit that authenticates a user based on authentication information of the user of the mobile terminal device obtained via the communication unit, a locking / unlocking unit that locks or unlocks the door if authentication by the authentication unit is successful, and a control unit that causes the mobile terminal device to transmit the value-added information stored in the memory unit via the communication unit in response to success of authentication by the authentication unit.

[0008] One aspect of the present disclosure provides a locking / unlocking method including the steps of: storing value-added information relating to an area in which the electronic locking device is installed in a memory unit of the electronic locking device; the electronic locking device communicating with a mobile terminal device; the electronic locking device authenticating a user based on authentication information of the user of the mobile terminal device obtained through the communication; the electronic locking device locking or unlocking a door if the authentication is successful; and the electronic locking device transmitting the value-added information stored in the memory unit to the mobile terminal device in response to the successful authentication. Effect of the Invention

[0009] According to one aspect of the present invention, it is possible to reduce the burden on facility managers in which electronic lock devices are installed and to increase convenience for users. [Brief description of the drawings]

[0011] An electronic lock device, a locking / unlocking method, and an electronic lock system to which the present invention is applied will be described below with reference to the drawings. The electronic lock system of the embodiment described below locks and unlocks an electronic lock installed on the door of a room in, for example, an accommodation facility or a warehouse. The object to be locked and unlocked by the electronic lock system of the embodiment is the door of an accommodation facility or a warehouse, but is not limited thereto, and any object that temporarily grants the authority to lock and unlock a locker, a rental space, an entrance / exit gate of an office building, a door of a rental car, etc., as long as the electronic key is used to lock and unlock the electronic lock, may be used.

[0012] FIG. 1 is a schematic diagram showing an example of an electronic lock system 1 in an embodiment. The electronic lock system 1 includes, for example, an electronic lock device 100, a mobile terminal device 200, and an information management server device 300. The electronic lock device 100 allows and prohibits the door 10 from being opened or closed by the doorknob 20 by locking and unlocking the door. The mobile terminal device 200 is, for example, an information processing device such as a smartphone held by a user. The information management server device 300 is, for example, a terminal device or a server device operated by an administrator of an accommodation facility. The electronic lock device 100, the mobile terminal device 200, and the information management server device 300 have a communication interface such as a NIC (Network Interface Card) or a wireless communication module for connecting to a network NW such as the Internet. The network NW may include, for example, a general-purpose network such as the Internet, and a private network such as local 5G, WiFi (registered trademark), or bluetooth. Furthermore, the electronic lock device 100, the mobile terminal device 200, and the information management server device 300 may each include a communication circuit compatible with NFC (Near Field Communication) and exchange information via NFC communication.

[0013] 2 is a schematic diagram showing an example of a functional configuration of a mobile terminal device 200 and an information management server device 300 according to an embodiment. The mobile terminal device 200 is an information processing device in which, for example, locking / unlocking application software is installed. The mobile terminal device 200 includes, for example, a communication unit 202, a user interface unit 204, an NFC communication circuit 206, a storage unit 208, and a processing unit 210.

[0014] The communication unit 202 is a communication circuit that communicates with the information management server device 300. The user interface unit 204 includes, for example, a display device, an operation input device, and a voice input / output device. The NFC communication circuit 206 transmits electromagnetic waves compatible with NFC and receives electromagnetic waves compatible with NFC.

[0015] The storage unit 208 is realized by, for example, a flash memory or an EEPROM (Electrically Erasable Programmable Read Only Memory). The storage unit 208 stores check-in information. The check-in information includes a door ID, a user ID, and authentication information. The authentication information is information generated based on an encryption key corresponding to the user. For example, when a common key encryption method is adopted, the encryption key is the same encryption key set in both the information management server device 300 and the electronic lock device 100. In this case, the information management server device 300 generates authentication information by encrypting the user ID using the encryption key, and transmits the generated authentication information to the mobile terminal device 200 to store the authentication information in the storage unit 208. When the mobile terminal device 200 transmits the user ID and authentication information to the electronic lock device 100 when locking / unlocking the door 10, the electronic lock device 100 encrypts the received user ID with an encryption key stored therein in advance to generate authentication information, and compares the generated authentication information with the received authentication information. The authentication information is, for example, information obtained by encrypting the door ID or the user ID with the encryption key of the user, but is not limited thereto, and the authentication information may be information necessary for authentication processing, such as a password. The communication unit 302 communicates with the information management server device 300, for example, when using an accommodation facility. The processing unit 210 acquires check-in information from the communication unit 202. The storage unit 208 stores the check-in information acquired by the processing unit 210. The storage unit 208 stores added value information related to the area in which the electronic lock device 100 is installed, which will be described later.

[0016] The processing unit 210 executes application software for locking and unlocking stored in a program memory by a processor such as a CPU (Central Processing Unit). The processing unit 210 controls the communication unit 202, the user interface unit 204, the NFC communication circuit 206, and the storage unit 208 in accordance with the application software for locking and unlocking based on an operation accepted by the user interface unit 204.

[0017] The information management server device 300 is a server device for managing users in order to rent out spaces such as guest rooms of an accommodation facility. The information management server device 300 includes, for example, a communication unit 302, an information management unit 304, and a storage unit 306. The communication unit 302 is a communication circuit that communicates with the mobile terminal device 200.

[0018] The storage unit 306 is configured, for example, by a hard disk drive (HDD), a solid state drive (SSD), a flash memory, an EEPROM, a random access read / write memory (RAM), a read only memory (ROM), or any combination of these storage media. The storage unit 306 stores, for example, electronic key information and user information. The electronic key information is encryption key information for each user. The user information is information about the user, such as a user ID, the door ID of the guest room used by the user, and expiration date information such as the length of stay.

[0019] The information management unit 304 has a check-in function that transmits check-in information to the mobile terminal device 200 when a user checks in. Specifically, the information management unit 304 reads out a door ID, a user ID, and authentication information for authentication from the storage unit 306 based on a request from the mobile terminal device 200, and transmits the read information to the mobile terminal device 200.

[0020] FIG. 3 is a block diagram showing an example of the configuration of the electronic lock device 100 according to the embodiment. The electronic lock device 100 of the embodiment does not have a function of connecting to a server device such as an information management server device 300, and does not have a power source. Such an electronic lock device 100 that is not connected to a server device is called, for example, an offline electronic lock. Also, an electronic lock device 100 that does not have a power source is called a battery-less electronic lock. The electronic lock device 100 of the embodiment is described as an example applied to an offline electronic lock or a battery-less electronic lock, but is not limited thereto. The electronic lock device 100 includes, for example, an antenna unit 110, an IC chip 120, a rectifier circuit 130, a control microcomputer 140, and a locking / unlocking mechanism 150. In the present embodiment, the locking / unlocking mechanism 150 may perform both a locking operation and an unlocking operation, but is not limited thereto, and may only perform an unlocking operation.

[0021] The antenna unit 110 is an example of a communication unit that communicates with a mobile terminal device. The antenna unit 110 receives electromagnetic waves compatible with NFC from the mobile terminal device 200. The transmission method of the electromagnetic waves compatible with NFC is, for example, a radio wave method (microwave method), but may be an electromagnetic induction method. When the electromagnetic waves for NFC communication are in the UHF band or 2.45 GHz band, the electromagnetic waves may be transmitted and received by a radio wave method (microwave method), and when the electromagnetic waves for NFC communication are in a low frequency of 13.56 MHz or less, the electromagnetic waves may be transmitted and received by an electromagnetic induction method. The antenna unit 110 outputs an electric signal corresponding to the electromagnetic waves received from the mobile terminal device 200 to the IC chip 120.

[0022] The IC chip 120 performs a predetermined decoding process on the electric signal corresponding to the electromagnetic waves to acquire the check-in information transmitted from the mobile terminal device 200. The IC chip 120 performs a predetermined process to output a lock / unlock signal to the control microcomputer 140. Note that the lock signal or unlock signal may also be referred to as a lock / unlock signal.

[0023] The rectifier circuit 130 generates DC power by rectifying an electric signal corresponding to the electromagnetic waves. The rectifier circuit 130 supplies the DC power to the control microcomputer 140 and the locking / unlocking mechanism 150. When a lock / unlock signal is supplied from the IC chip 120, the control microcomputer 140 outputs a drive signal to the lock / unlock mechanism 150. The lock / unlock mechanism 150 moves the tip of the deadbolt 152 toward the strike 22 of the door 10 in accordance with the drive signal. The locking / unlocking mechanism 150 may include, for example, an actuator such as a solenoid and a motor, and may include a cylinder that generates a driving force, such as a hydraulic cylinder, a pneumatic cylinder, or a water hydraulic cylinder, or may include an artificial muscle (soft actuator) using a polymer, etc. The rectifier circuit 130, the control microcomputer 140, and the locking / unlocking mechanism 150 function as a locking / unlocking unit that locks or unlocks the door 10 when authentication by the authentication unit 124 in the IC chip 120 is successful.

[0024] Regarding locking, the door 10 may be automatically locked when closed by a latch mechanism (such as a spring) of the locking / unlocking mechanism 150 (auto-lock). In this case, the locking / unlocking mechanism 150 compresses a spring provided on a bar (rod-shaped member) of the latch when unlocking. When the locking / unlocking mechanism 150 is stopped, the latch is automatically locked by the restoring force of the spring. However, the spring is only an example, and rubber or other elastic bodies may be used. The bar of the latch may be a cylindrical part (such as a cylinder) that contains a fluid such as gas or liquid. In addition, in reality, the invention is not limited to these examples, and an auto-lock method that does not use electricity for locking may be used. At this time, the electronic lock device 100 can maintain the unlocked state by constantly receiving electromagnetic waves corresponding to NFC. However, a mechanism (such as a lock and a stopper) that can maintain the unlocked state after unlocking and release the unlocked state when locking may be provided.

[0025] When the antenna unit 110 of such an electronic lock device 100 receives electromagnetic waves output from the NFC communication circuit 206, power is applied to the rectifier circuit 130, the control microcomputer 140, and the locking / unlocking mechanism 150, and the IC chip 120 is activated.

[0026] 4 is a diagram showing an example of a functional configuration of IC chip 120 according to the embodiment. IC chip 120 includes, for example, acquisition unit 122, authentication unit 124, storage unit 126, and lock / unlock signal output unit 128. The acquisition unit 122 receives a signal from the antenna unit 110 and outputs a lock / unlock signal to the control microcomputer 140 . The authentication unit 124 authenticates the user of the mobile terminal device 200 based on authentication information of the user acquired via the antenna unit 110 . The storage unit 126 stores value-added information related to the area where the electronic lock device 100 is installed. The storage unit 126 stores, for example, a door ID, value-added information, and a current user ID. The door ID is a fixed value of the electronic lock device 100. The current user ID is the ID of the current user of the electronic lock device 100, and is updated based on the check-in information of the user. The value-added information is information related to the area where the electronic lock device 100 is installed. The value-added information is, for example, facility information (guidance, benefits) related to the facility, and door-related information representing an interior map, a surrounding guide map, or an evacuation route with the position of any door 10 (door) of the facility as the starting point or center. The value-added information may be authority information given to the user. The authority information is, for example, a discount coupon indicating the authority of a discount given to the user for using a room in an accommodation facility. The IC chip 120 functions as a control unit that causes the mobile terminal device 200 to transmit information stored in the storage unit 126 via the antenna unit 110 in response to a successful authentication by the authentication unit 124 .

[0027] FIG. 5 is a block diagram showing another example of the configuration of the mobile terminal device 200 according to the embodiment. The mobile terminal device 200 according to the embodiment receives the value-added information from the electronic lock device 100 and stores it in the storage unit 208. The mobile terminal device 200 uses the value-added information to perform display or audio output through the user interface unit 204. This enables the mobile terminal device 200 to notify the user of the value-added information.

[0028] FIG. 6 is a sequence diagram showing an example of the operation of the electronic lock system 1 in the embodiment. First, the communication unit 202 of the mobile terminal device 200 transmits reservation information S10 to the information management server device 300 (step ST10). The reservation information includes information such as a user ID and a reservation period. The communication unit 302 of the information management server device 300 receives the reservation information S10 and transmits check-in information S12 to the mobile terminal device 200 (step ST20). The communication unit 202 receives the check-in information from the information management server device 300, and the storage unit 208 stores the check-in information (step ST12).

[0029] Next, the NFC communication circuit 206 transmits electromagnetic waves S14 compatible with NFC to the electronic lock device 100 near the door 10 of the accommodation facility (step ST14). The electronic lock device 100 receives the electromagnetic waves S14, starts up, and transitions to a standby state (step ST30).

[0030] The NFC communication circuit 206 transmits a lock / unlock command S16 including the check-in information S12 stored in the storage unit 208 to the electronic lock device 100 (step ST16). The electronic lock device 100 receives the lock / unlock command S16 including the check-in information S12 (step ST32), and the IC chip 120 checks the door ID included in the check-in information S12 (step ST34). The IC chip 120 compares the door ID included in the check-in information S12 with the door ID stored in the storage unit 126, and if they match, determines that the door ID included in the check-in information is correct (step ST36). If the received door ID is incorrect (step ST36: NO), the IC chip 120 proceeds to step ST58.

[0031] If the received door ID is correct (step ST36: YES), the IC chip 120 encrypts the received user ID with an encryption key to generate authentication information (step ST38). The IC chip 120 compares the generated authentication information with the received authentication information (step ST40) and determines whether the authentication has been successful (step ST42). The IC chip 120 determines that the authentication has been successful if both pieces of authentication information match, and determines that the authentication has failed if both pieces of authentication information do not match. If the authentication has failed (step ST42: NO), the IC chip 120 proceeds to step ST58.

[0032] If the authentication is successful (step ST42: YES), the IC chip 120 checks the user ID included in the check-in information S12 (step ST44). If the user ID stored in the storage unit 126 differs from the user ID included in the check-in information S12, the IC chip 120 determines that the user ID is new (step ST46: YES). If the user ID stored in the storage unit 126 is the same as the user ID included in the check-in information, the IC chip 120 determines that the user ID is not new (step ST46: NO).

[0033] If the user ID is new, the IC chip 120 stores the new user ID as a current user ID in the storage unit 126 (step ST48) and reads the value-added information from the storage unit 126 (step ST50). The locking / unlocking signal output unit 128 transmits a locking / unlocking signal to the control microcomputer 140, and the control microcomputer 140 operates the locking / unlocking mechanism 150 to perform the locking or unlocking operation (step ST52). If there is value-added information, the IC chip 120 generates a success response of the locking or unlocking operation including the value-added information (step S54) and transmits the generated success response S18 to the mobile terminal device 200 (step ST56). The NFC communication circuit 206 receives the success response S18 from the electronic lock device 100 (step ST18).

[0034] If it is determined in step ST46 that the user ID is not new, the IC chip 120 performs a locking or unlocking operation (step ST52), generates a success response to the locking or unlocking operation that does not include value-added information (step S54), and transmits the generated success response S18 to the mobile terminal device 200 (step ST56). Note that, if there is any value-added information that has not been transmitted, the IC chip 120 may transmit the value-added information that has not been transmitted. Note that, although the IC chip 120 transmits the value-added information when it determines that the user is a new user, it may transmit the value-added information again in step ST54.

[0035] When message information indicating a message for the user is stored in the storage unit 126, the IC chip 120 may transmit the message information to the mobile terminal device 200 based on the authentication information when unlocking the door 10. When the authentication is successful and the user ID is not new but new message information is included in the added-value information, the IC chip 120 can generate a success response including the updated message information and transmit it to the mobile terminal device 200.

[0036] In step ST58, the IC chip 120 generates a failure response to the locking or unlocking operation, and transmits the generated failure response S18 to the mobile terminal device 200 (step ST56). The NFC communication circuit 206 receives the failure response S18 from the electronic lock device 100 (step ST18).

[0037] FIG. 7(A) is a diagram showing an example of another functional configuration of IC chip 120 in an embodiment, and FIG. 7(B) is a diagram showing an example of another functional configuration of mobile terminal device 200 in an embodiment. In the above-described embodiment, the storage unit 126 of the IC chip 120 may store a plurality of pieces of value-added information corresponding to a plurality of languages ​​(FIG. 7(A)). When the locking / unlocking mechanism 150 unlocks the door 10, the IC chip 120 transmits the value-added information corresponding to any one of the plurality of languages ​​to the mobile terminal device 200. At this time, the IC chip 120 pre-stores language information corresponding to a user ID, for example, and transmits the value-added information in any one of the languages ​​to the mobile terminal device 200 based on the language information corresponding to the user ID. This enables the mobile terminal device 200 to store the value-added information in a language suitable for the user and present it to the user (FIG. 7(B)).

[0038] FIG. 8(A) is a diagram showing an example of another functional configuration of IC chip 120 in an embodiment, and FIG. 8(B) is a diagram showing an example of another functional configuration of mobile terminal device 200 in an embodiment. In the above-mentioned embodiment, as shown in Fig. 8(A), the storage unit 126 of the IC chip 120 may store a warehouse ID as a fixed value, warehouse information as added value information, and an encryption key. The warehouse information includes, for example, a floor plan of the warehouse in which the electronic lock device 100 is installed, a department management area, and a user management storage list. On the other hand, the storage unit 208 of the mobile terminal device 200 may store lock / unlock information instead of the check-in information. The lock / unlock information includes, for example, a warehouse ID, a department ID, a user ID, and authentication information (FIG. 8(B)). The mobile terminal device 200 transmits lock / unlock information to the electronic lock device 100, and if authentication based on the authentication information is successful, acquires a warehouse floor plan corresponding to the warehouse ID, a department management area corresponding to the department ID, and a user management storage list corresponding to the user ID. This allows the mobile terminal device 200 to present the acquired value-added information to the user.

[0039] FIG. 9 is a sequence diagram showing an example of another operation of the electronic lock system 1 in the embodiment. First, the communication unit 202 of the mobile terminal device 200 transmits registration information S20 to the information management server device 300 (step ST60). The registration information includes information such as the department and the user. The communication unit 302 of the information management server device 300 receives the registration information S20 and transmits locking / unlocking information S22 to the mobile terminal device 200 (step ST70). The communication unit 202 receives the locking / unlocking information S22 from the information management server device 300, and the memory unit 208 stores the locking / unlocking information (step ST62).

[0040] Next, the NFC communication circuit 206 transmits NFC-compatible electromagnetic waves S14 to the electronic lock device 100 near the door 10 of the accommodation facility (step ST64). The electronic lock device 100 receives the electromagnetic waves S24, starts up, and transitions to a standby state (step ST70).

[0041] The NFC communication circuit 206 transmits a lock / unlock command S26 including the lock / unlock information S22 stored in the storage unit 208 to the electronic lock device 100 (step ST66). The electronic lock device 100 receives the lock / unlock command S26 (step ST72), and the IC chip 120 checks the warehouse ID included in the lock / unlock information (step ST74). The IC chip 120 compares the warehouse ID with the warehouse ID stored in the storage unit 126, and if they match, determines that the warehouse ID included in the lock / unlock information is correct (step ST76). If the received warehouse ID is incorrect (step ST76: NO), the IC chip 120 proceeds to step ST98.

[0042] If the received warehouse ID is correct (step ST76: YES), the IC chip 120 encrypts the received user ID with an encryption key to generate authentication information (step ST78). The IC chip 120 compares the generated authentication information with the received authentication information (step ST80) and determines whether the authentication has been successful (step ST82). The IC chip 120 determines that the authentication has been successful if both pieces of authentication information match, and determines that the authentication has failed if the two pieces of authentication information do not match. If the authentication has failed (step ST82: NO), the IC chip 120 proceeds to step ST98.

[0043] If the authentication is successful (step ST82: YES), the IC chip 120 checks whether the door is locked or unlocked (step ST84). If the door is locked by the locking / unlocking mechanism 150, the IC chip 120 determines that the door is to be unlocked, and if the door is unlocked by the locking / unlocking mechanism 150, the IC chip 120 determines that the door is locked. When unlocking is to be performed (step ST86: YES), the IC chip 120 selects value-added information permitted by the user ID or the department ID (step ST88) and reads the value-added information from the storage unit 126 (step ST90). The locking / unlocking signal output unit 128 transmits a locking / unlocking signal to the control microcomputer 140, and the control microcomputer 140 operates the locking / unlocking mechanism 150 to perform the locking or unlocking operation (step ST92). The IC chip 120 generates a success response of the unlocking operation including the value-added information (step S94) and transmits the generated success response S28 to the mobile terminal device 200 (step ST96). The NFC communication circuit 206 receives the success response S28 from the electronic lock device 100 (step ST68).

[0044] If locking is to be performed (step ST86: NO), the IC chip 120 performs the locking operation (step ST92), generates a success response of the locking operation including the value-added information (step S94), and transmits the generated success response S28 to the mobile terminal device 200 (step ST96). As a result, when a user enters the warehouse, the electronic lock device 100 transmits value-added information corresponding to the user ID and the department ID to the mobile terminal device 200 in response to successful authentication, allowing the user to confirm the value-added information.

[0045] In addition, a user may bring an object into the warehouse, move an object, or take an object out, and the layout of the warehouse may change. In this case, the mobile terminal device 200 updates the floor plan of the warehouse, the department management area, or the user management storage list stored in the storage unit 208. When the electronic lock device 100 receives a success response S28 of the locking operation, it may transmit the updated information to the electronic lock device 100. This allows the electronic lock device 100 to update the information stored in the storage unit 126 based on the information received from the mobile terminal device 200.
