(First embodiment)
A first embodiment of an electronic lock system, an electronic lock management method, and an electronic lock management application will be described below.

As shown in FIG. 1, the building 1 has an electronic lock system 4 that performs user authentication and controls the electronic lock 3 of the opening/closing member 2 of the building 1 . The electronic lock system 4 is preferably a digital key system 6 that authenticates the terminal 5 and activates the electronic lock 3 by, for example, short-range wireless communication. Thus, in the case of this example, the electronic lock system 4 is a system capable of controlling the electronic lock 3 by the terminal 5 instead of the electronic key that is the exclusive key for the building 1 . The opening/closing body 2 may be, for example, the door 7 of the building 1 .

The terminal 5 is, for example, a multifunctional terminal, and an example thereof is a high-performance mobile phone. The terminal 5 becomes the key of the building 1 (the opening/closing body 2), that is, the digital key 8 by being given the key information Dk from an external medium (for example, a server).

The electronic lock system 4 includes a wireless authentication device 11 that authenticates the digital key 8 by short-range wireless communication. A wireless authentication device 11 is installed in a building 1 . The wireless authentication device 11 may be pre-installed in the building 1 or may be retrofitted in the building 1 . The wireless authentication device 11 authenticates the digital key 8 by short-range wireless communication via the antenna 12 . The antenna 12 is preferably arranged inside a knob 13 (see FIG. 4 and the like) provided on the opening/closing body 2 .

The short-range wireless communication may be PAN (Personal Area Network) communication, LAN (Local Area Network) communication, or short-range wireless communication. Personal area network communication includes, for example, Bluetooth (registered trademark) communication, UWB (Ultra Wide Band) communication, and the like. Bluetooth communication is preferably BLE (Bluetooth Low Energy), for example. LAN communication includes, for example, Wi-Fi (registered trademark) communication. Short-range wireless communication includes, for example, NFC (Near Field Communication) as a type of RFID.

The terminal 5 (digital key 8) includes a terminal control unit 18 that controls the operation of the terminal 5, a network module 19 that performs network communication, a communication module 20 that performs short-range wireless communication, and data storage. It includes a memory 21, an operation unit 22 used when operating the terminal 5, and a display unit 23 for displaying a screen. The terminal 5 (digital key 8 ) performs short-range wireless communication with the wireless authentication device 11 via the communication module 20 . The operating unit 22 is, for example, a power button. The display unit 23 is preferably a touch panel, for example.

The terminal 5 has key information Dk registered in the memory 21 that is used for authentication by short-range wireless communication. The terminal 5 preferably downloads the key information Dk by various methods such as downloading from a server (not shown), wireless acquisition from a master key, and image reading of code information. The key information Dk may be downloaded to the terminal 5 from the outside, or may be written in advance at the time of shipment. The wireless authentication device 11 determines whether or not the building 1 can be used by authenticating the key information Dk registered in the terminal 5 .

A digital key application 24 necessary for operating the terminal 5 as the digital key 8 is registered in the memory 21 of the terminal 5 . The digital key application 24 is acquired, for example, from an external medium (such as a server) through network communication, and written and stored in the memory 21 . By registering the digital key application 24 in the terminal 5, it becomes possible to download the key information Dk to the terminal 5 and operate the electronic lock 3 of the opening/closing body 2 in the terminal 5. FIG.

The building 1 has a controller 25 that controls the electronic lock 3 based on the authentication result of the wireless authentication device 11 . When authentication by the wireless authentication device 11 is successful, the controller 25 permits control of the electronic lock 3 and switches the electronic lock 3 between locked and unlocked states. On the other hand, if the authentication by the wireless authentication device 11 is not established, the controller 25 is not permitted to control the electronic lock 3 and cannot operate the electronic lock 3 .

FIG. 2 illustrates the procedure for authenticating the terminal 5 (digital key 8).
In step 101, the wireless authentication device 11 periodically and repeatedly transmits advertisements for notifying information related to communication of the device itself. Advertise is a type of packet data, for example, and is regularly transmitted from the wireless authentication device 11 at all times.

In step 102, when the terminal 5 receives the Advertise transmitted from the wireless authentication device 11, it performs scanning processing. In addition, it is preferable that the terminal 5 starts the scanning process, for example, when the received signal strength when the advertisement is received reaches or exceeds a specified value. At this time, after the scanning process, the terminal 5 transmits a connection request to the wireless authentication device 11 as a request for providing details of the short-range wireless communication.

In step 103, when the terminal 5 and the wireless authentication device 11 perform the above exchanges, the terminal 5 and the wireless authentication device 11 shift to a state in which short-range wireless communication is connected, that is, a state of communication connection.
In step 104, the terminal 5 and the wireless authentication device 11 authenticate the terminal 5 when the short-range wireless communication shifts to the communication connection state. In this example, for example, in response to a request from the wireless authentication device 11, the terminal 5 transmits the key information Dk registered in the memory 21 to the wireless authentication device 11 by short-range wireless communication. Upon receiving the key information Dk, the wireless authentication device 11 authenticates the key information Dk. In the case of this example, when the wireless authentication device 11 can decrypt the key information Dk correctly and the authentication of the key information Dk is established, for example, a record equivalent to permission to use the building 1 (in the case of sharing, , reservation time, etc.), a session key to be used in subsequent short-range wireless communication, a terminal ID that is a unique ID of the terminal 5, and the like can be obtained. On the other hand, if the key information Dk is not correct, the wireless authentication device 11 forcibly terminates the process and does not permit the use of the building 1 .

In step 105, when the key information Dk is authenticated, the terminal 5 and the wireless authentication device 11 enter an authentication completion state in which authentication is recognized. The authentication completed state is a state in which both the terminal 5 and the wireless authentication device 11 know a common session key and terminal ID. Thereby, the locking/unlocking operation of the opening/closing body 2 of the building 1 becomes possible.

In step 106, the terminal 5 and the wireless authentication device 11 execute communication to confirm whether or not short-range wireless communication is maintained after the transition to the authentication completed state. In the case of this example, each of the terminal 5 and the wireless authentication device 11 transmits periodic radio waves at predetermined periodic intervals (connection interval), and confirms whether or not a response to the periodic radio waves can be received. Monitor whether the establishment is maintained. That is, if the terminal 5 transmits periodic radio waves at predetermined periodic intervals and can receive a response to the periodic radio waves, it is determined that the communication is maintained, and the wireless authentication device 11 also executes similar processing.

When the terminal 5 becomes unable to receive the response to the periodic radio waves it transmits from the wireless authentication device 11, it disconnects the communication. Also, when the wireless authentication device 11 becomes unable to receive a response to the periodic radio waves it transmits from the terminal 5, it disconnects the communication.

FIG. 3 shows an example of a procedure for locking and unlocking the opening/closing member 2 with the digital key 8. As shown in FIG.
At step 201, the digital key 8 and the wireless authentication device 11 are shifted to the authentication complete state through short-range wireless communication. When the digital key 8 whose key information Dk has been authenticated is reconnected to the wireless authentication device 11, it is preferable to shift to the authentication completed state by authentication using the session key.

In step 202, when the digital key 8 is operated to lock/unlock the opening/closing member 2, the digital key 8 transmits a remote operation request Sa corresponding to the operation to the wireless authentication device 11 by short-range wireless communication. The unlocking operation is, for example, touching the unlocking button 33 (see FIG. 4) displayed on the display section 23 of the digital key 8 . In the unlocking operation, the remote operation request Sa is the unlocking request Sa1. The unlocking operation may be performed by operating a switch or a sensor provided on the knob 13 of the opening/closing body 2, for example. The locking operation is, for example, a touch operation of a locking button (not shown) displayed on the display section 23 of the digital key 8 . In the case of the locking operation, the remote operation request Sa is the locking request Sa2. The locking operation may be performed by operating a switch or a sensor provided on the knob 13 of the opening/closing body 2, for example.

When receiving the remote operation request Sa from the terminal 5, the wireless authentication device 11 outputs to the controller 25 an operation request reception notification Sb indicating that the remote operation request Sa has been received if the authentication is completed. The operation request reception notification Sb is the unlocking request reception notification Sb1 if the received remote operation request Sa is the unlocking request Sa1, and the locking request reception notification Sb2 if the received remote operation request Sa is the locking request Sa2. is.

In step 203 , the controller 25 locks and unlocks the opening/closing body 2 when receiving the operation request reception notification Sb from the wireless authentication device 11 . In the case of this example, the controller 25 unlocks the opening/closing member 2 when receiving the unlock request reception notification Sb1. At this time, the controller 25 unlocks the electronic lock 3, and stops the operation of the electronic lock 3 when the detector 26 detects that the lock member (not shown) of the electronic lock 3 is positioned at the unlocked position. .

Further, the controller 25 locks the opening/closing body 2 when receiving the lock request reception notification Sb2. At this time, the controller 25 locks the electronic lock 3, and stops the operation of the electronic lock 3 when the detector 26 detects that the lock member (not shown) of the electronic lock 3 is positioned at the locked position.

As shown in FIG. 1 , the electronic lock system 4 has an electronic lock management function for managing the current state of the electronic lock 3 using the terminal 5 . The electronic lock management function of this example uses the terminal 5 to manage changes in the state of the electronic lock 3 and failure diagnosis results of the electronic lock 3 as the current state of the electronic lock 3 . It is preferable that the state change of the electronic lock 3 is, for example, information indicating which key is used to switch between locking and unlocking. The failure diagnosis is a process of diagnosing whether or not the opening/closing member 2 and the electronic lock 3 are abnormal. A fault diagnosis is preferably performed periodically in the controller 25 .

The electronic lock system 4 has an electronic lock management application 29 as an application for executing electronic lock management functions. Electronic lock management application 29 is stored in memory 21 of terminal 5 . In this example, the electronic lock management application 29 is obtained, for example, from an external medium (for example, a server, etc.) via network communication. Note that the electronic lock management application 29 may be integrated with the digital key application 24 .

The electronic lock system 4 includes a control unit 30 that transmits state information St regarding the state of the opening/closing body 2 to the terminal 5 by wireless communication and causes the terminal 5 to hold the state information St. In this example, the controller 30 is provided in the controller 25 of the building 1, for example. In the case of this example, the control unit 30 transmits the state information St to the terminal 5 by short-range wireless communication, and stores it in the memory 21 of the terminal 5 . In the case of this example, the status information St includes a status change notification St1, which is a notification that the status of the electronic lock 3 has changed, and a failure diagnosis result notification St2, which is the diagnosis result of the failure diagnosis of the electronic lock 3.

The electronic lock system 4 includes a fault diagnosis function section 31 for diagnosing whether the opening/closing body 2 and the electronic lock 3 are abnormal. The fault diagnosis function unit 31 is provided in the controller 25 of the building 1, for example. The failure diagnosis function unit 31 determines whether or not an abnormality has occurred in the opening/closing member 2 based on, for example, the detection signal Su of the detection unit 26 provided in the opening/closing member 2 and the current state of the electronic lock 3. is preferred. The detection unit 26 detects, for example, that the electronic lock 3 is in the unlocked state, detects that the electronic lock 3 is in the locked state, detects that the opening/closing member 2 is in the closed state, There are those that detect that the opening/closing body 2 is in an open state, those that detect the inclination of the opening/closing body 2, and the like. The detection unit 26 may be either sensors or switches.

The electronic lock system 4 includes a display processing section 32 that displays the state information St held in the memory 21 on the display section 23 of the terminal 5 . In this example, the display processing unit 32 is provided in the terminal 5 (terminal control unit 18). In this example, the display processing unit 32 preferably displays the state information St on the display unit 23 of the terminal 5 when the display operation of the state information St is performed on the terminal 5, for example. As for the display of the state information St, it is preferable to display a list of the past state information St as the operation history of the electronic lock 3 on the screen of the display unit 23, for example.

Next, the operation of the electronic lock system 4 of this embodiment will be described.
As shown in FIG. 4, for example, an example of unlocking the opening/closing body 2 with the terminal 5 from the outside will be given. Note that when the terminal 5 enters the communication area of the wireless authentication device 11 in the building 1, the terminal 5 and the wireless authentication device 11 transition to a communication connection state. Then, if the terminal 5 is authorized, both the terminal 5 and the wireless authentication device 11 shift to the authentication completed state. At this time, if the key information Dk of the terminal 5 has been authenticated, for example, the terminal 5 is authenticated with a predetermined session key obtained by decrypting the key information Dk, and the terminal 5 and the wireless authentication device 11 are in an authentication completed state. It is preferable to move to

When unlocking the opening/closing member 2, for example, an unlock button 33 is displayed on the display unit 23 of the terminal 5, and the unlock button 33 is touch-operated. When the terminal 5 detects that the unlocking button 33 on the screen of the display unit 23 has been touched, it transmits an unlocking request Sa1 to the wireless authentication device 11 of the building 1 by short-range wireless communication. When the wireless authentication device 11 receives the unlocking request Sa1 transmitted from the authorized terminal 5, the electronic lock 3 of the opening/closing member 2 is switched from the locked state to the unlocked state based on the reception of the unlocking request Sa1.

As shown in FIG. 5, when the state of the electronic lock 3 changes, the control unit 30 transmits a state change notification St1 related to the state change at that time from the wireless authentication device 11 to the terminal 5 by short-range wireless communication. do. In the case of unlocking the opening/closing body 2, the state change notification St1 is preferably a notification such as "unlocked by the third registered terminal 5". When the terminal 5 receives the state change notification St1 transmitted from the wireless authentication device 11, it writes it in the memory 21 and stores it.

The terminal 5 to which the status change notification St1 is saved is not limited to the terminal 5 on which the opening/closing member 2 has been unlocked. For example, if there are a plurality of terminals 5 that are in communication connection with the wireless authentication device 11, these terminals 5 may store the status change notification St1. If there are a plurality of terminals 5 (for example, terminals 5 that are in a communication connection state) that can store the status change notification St1, the status change notification St1 may be stored only in a specific terminal 5 . As a specific method, for example, either a form of switching between valid and invalid of saving on the terminal 5 or a form of inputting a command to the controller 25 and designating the terminal 5 as the save destination may be used.

As shown in FIG. 6, the control unit 30 periodically transmits a failure diagnosis result notification St2 from the wireless authentication device 11 to the terminal 5 by short-range wireless communication. In the case of this example, the failure diagnosis function unit 31 diagnoses whether or not there is an abnormality in the opening/closing member 2 and the electronic lock 3 at regular intervals. 11 to the terminal 5. The failure diagnosis result notification St2 is preferably, for example, a notification such as "the opening/closing member 2 is closed, the electronic lock 3 is in the locked state, and there is no abnormality". When the terminal 5 receives the failure diagnosis result notification St2 transmitted from the wireless authentication device 11, it writes it in the memory 21 and stores it.

If there are a plurality of terminals 5 that are in a state of communication connection with the wireless authentication device 11, the failure diagnosis result notification St2 may be stored in these plurality of terminals 5. FIG. Further, if there are a plurality of terminals 5 (for example, terminals 5 that are in a communication connection state) that can serve as storage destinations for the failure diagnosis result notification St2, the storage destination may be specified in the same manner as the status change notification St1. . Furthermore, if there are a plurality of terminals 5, the state change notification St1 and the failure diagnosis result notification St2 may be stored in different terminals 5 respectively.

An example of an "abnormal" diagnosis in the failure diagnosis is, for example, a case where the opening/closing body 2 is in the closed state although the electronic lock 3 is in the locked state. Other than this, for example, when the detection unit 26 for both locking detection and unlocking detection is "on", or when a sensor that detects the inclination of the opening/closing body 2 In some cases, it is detected that the camera is tilted.

As shown in FIGS. 7A and 7B, the display processing unit 32 displays a confirmation screen 34 of the state information St on the display unit 23 when the terminal 5 performs an operation to display the state information St. The confirmation screen 34 includes, for example, a screen for displaying the status change notification St1 shown in FIG. (referred to as a failure diagnosis result confirmation screen 36).

The status change confirmation screen 35 has, for example, an item for displaying "terminal number", an item for displaying "equipment", an item for displaying "date", and an item for displaying "change of status". The item for displaying the “terminal number” is an item for displaying the registered terminal number among the plurality of terminals 5 registered in the controller 25 . The item that displays "equipment" is an item that displays the equipment (the electronic lock 3 in this example) that has undergone a state change. The item "date" is an item for displaying the date and time when the state change occurred. The item for displaying "state change" is an item for displaying the content of the state change (for example, switching from unlocked to locked). The status change confirmation screen 35 displays these items for each received status change notification St1.

The failure diagnosis result confirmation screen 36 has, for example, an item for displaying "Date" and an item for displaying "Status". The item "date" is an item for displaying the date and time when the failure diagnosis was performed. The item for displaying the “state” is an item for displaying the specific content of the failure diagnosis result. The failure diagnosis result confirmation screen 36 displays these items for each failure diagnosis result notification St2. The state change confirmation screen 35 and the failure diagnosis result confirmation screen 36 may be displayed on different screens, or may be collectively displayed on the same screen.

When the user wants to check the status change notification St1, the user performs an operation to display the status change confirmation screen 35 on the terminal 5 . Upon detecting this operation, the terminal 5 displays the state change confirmation screen 35 on the display unit 23 . This allows the user to check the past operation history of the opening/closing body 2 and the electronic lock 3 from the status change confirmation screen 35 . Further, when the user wants to check the failure diagnosis result notification St2, the user performs an operation to display the failure diagnosis result confirmation screen 36 on the terminal 5 . Upon detecting this operation, the terminal 5 displays a failure diagnosis result confirmation screen 36 on the display unit 23 . As a result, the user can check the abnormality currently occurring in the opening/closing member 2 or the electronic lock 3 from the failure diagnosis result confirmation screen 36 .

According to the electronic lock system 4 of the above embodiment, the following effects can be obtained.
(1) The electronic lock system 4 authenticates the terminal 5 by wireless communication and controls the operation of the electronic lock 3 of the opening/closing body 2 provided in the building 1 . The control unit 30 of the electronic lock system 4 transmits the state information St regarding the state of the opening/closing member 2 to the terminal 5 by wireless communication, and stores the state information St in the memory 21 of the terminal 5 .

According to the configuration of this example, the state information St regarding the state of the opening/closing member 2 is transmitted to the terminal 5 and held in the terminal 5 . Since the terminal 5 is used to store the state information St in this way, there is no need to separately provide a resource for holding the state information St. Therefore, the state information St of the electronic lock 3 can be held without adding dedicated hardware.

(2) The state information St is a state change notification St1 that is a notification that the state of the electronic lock 3 has changed. According to this configuration, the operation history of the electronic lock 3 can be retained and accumulated in the terminal 5 as the status change notification St1.

(3) Since the state change notification St1, which is the operation history of the electronic lock 3, is held in the terminal 5, for example, when the electronic lock 3 is frequently operated (including the opening and closing of the opening/closing body 2), such as at home, the opening/closing body 2 usage status can be grasped.

(4) When the state of the electronic lock 3 changes, the control unit 30 transmits to the terminal 5 a state change notification St1 related to the state change at that time. According to this configuration, the state change notification St1 is transmitted to the terminal 5 each time the state of the electronic lock 3 changes, so the terminal 5 can acquire the state change notification St1 at the optimum timing.

(5) The status information St is a failure diagnosis result notification St2 that is the result of failure diagnosis of the electronic lock 3 . According to this configuration, the terminal 5 can hold and accumulate the failure diagnosis results of the electronic lock 3 executed in the building 1 .

(6) The control unit 30 periodically transmits the failure diagnosis result notification St2 to the terminal 5 at regular intervals. According to this configuration, since the trouble diagnosis result notification St2 is automatically transmitted periodically, it is not troublesome to acquire the trouble diagnosis result notification St2.

(7) The electronic lock system 4 includes a display processing section that displays the state information St held in the memory 21 on the display section 23 of the terminal 5 . According to this configuration, the state information St held in the memory 21 of the terminal 5 can be displayed on the display section 23 of the terminal 5, and the past operation of the electronic lock 3 can be confirmed as necessary.

(8) The electronic lock system 4 includes a wireless authentication device 11 that authenticates the terminal 5 by short-range wireless communication. The control unit 30 transmits the state information St to the terminal 5 via the antenna 12 of the wireless authentication device 11 . According to this configuration, in a system in which locking/unlocking of the electronic lock 3 of the opening/closing body 2 can be switched by the terminal 5 , the state information St of the electronic lock 3 can be held in the terminal 5 . Therefore, while using the terminal 5 as a key for the opening/closing body 2, the terminal 5 can also hold the state information St of the electronic lock 3, which contributes to the improvement of convenience.

(Second embodiment)
Next, a second embodiment will be described. The second embodiment is an embodiment in which the electronic key 41 is used as the key of the opening/closing body 2 instead of using the terminal 5 described in the first embodiment as the key (digital key 8) of the opening/closing body 2. FIG. Therefore, the same reference numerals are given to the same parts as in the first embodiment, and the description thereof is omitted, and only the different parts will be described in detail.

As shown in FIG. 8 , the electronic lock system 4 may be configured to lock and unlock the opening/closing member 2 of the building 1 with an electronic key 41 instead of the terminal 5 . In this case, the electronic lock system 4 includes a smart system that wirelessly authenticates the electronic key 41 in response to communication from the building 1, and a wireless key system that wirelessly authenticates the electronic key 41 in response to communication from the electronic key 41. including at least one of

In this example, the electronic lock system 4 includes a verification device 42 that authenticates the electronic key 41 by wireless authentication, and a communication module 43 that performs short-range wireless communication with the terminal 5 . The collation device 42 includes a transmitter 44 that transmits radio waves in the LF (Low Frequency) band and a receiver 45 that receives radio waves in the UHF (Ultra High Frequency) band. In the verification device 42, the ID code of the electronic key 41 registered in the verification device 42 is stored in a memory (not shown).

The electronic key 41 receives radio waves in the LF band and transmits radio waves in the UHF band. An ID code unique to the electronic key 41 is stored in a memory (not shown). The electronic key 41 has an operation button 46 that is operated when the electronic lock 3 is operated by the wireless key system. The operation button 46 may include, for example, any of a lock button that is operated when locking, an unlock button that is operated when unlocking, and an operation button that switches between locked and unlocked each time it is operated.

In the case of the smart system, the verification device 42 transmits a wake signal for activating the electronic key 41 by LF radio waves. When the electronic key 41 receives the wake signal transmitted from the verification device 42, the electronic key 41 switches from the standby state to the activated state, and executes communication with the verification device 42 for ID verification. At this time, the verification device 42 performs challenge-response authentication with the electronic key 41 and ID code verification for verifying the ID code of the electronic key 41 . If both the challenge-response authentication and the ID code matching are successful, the matching device 42 outputs an ID matching success notification to the controller 25 .

When the controller 25 receives the notification that the ID verification is established from the verification device 42, the operation of the opening/closing member 2 is permitted. Therefore, if the switch or button of the knob 13 of the opening/closing member 2 is operated while the electronic lock 3 is in the locked state, the electronic lock 3 is unlocked under ID collation. When the switch or button of the knob 13 of the opening/closing body 2 is operated while the electronic lock 3 is in the unlocked state, the electronic lock 3 is locked.

In the case of the wireless key system, when the operation button 46 of the electronic key 41 is operated, the electronic key 41 transmits an operation request to the verification device 42 according to the operated operation button 46 . When receiving an operation request operated from the electronic key 41 , the verification device 42 switches locking/unlocking of the electronic lock 3 by operating in accordance with the command of the operation request. For example, the verification device 42 switches the electronic lock 3 to the unlocked state when receiving the unlocking request as the operation request, and switches the electronic lock 3 to the locked state when receiving the locking request as the operation request.

The electronic lock management function of this example is executed by causing the communication module 43 connected to the controller 25 to perform short-range wireless communication with the terminal 5 . The communication module 43 includes an antenna for transmitting and receiving radio waves for short-range wireless communication, a communication circuit for signal processing of radio waves for communication, and the like. The communication module 43 is preferably arranged on the knob 13 of the opening/closing body 2, for example.

The control unit 30 transmits the state information St from the communication module 43 to the terminal 5 every time it detects a change in the state of the electronic lock 3 and causes the terminal 5 to store the state information St. The status information St includes at least one of the status change notification St1 and the failure diagnosis result notification St2, as described above. Upon receiving the state information St transmitted from the communication module 43 , the terminal 5 stores it in the memory 21 .
