As shown in FIGS. 1 and 2, the electric lock device 1 according to the present embodiment is a device that is attached to a door of a building and locks and unlocks the door.
This electric lock device 1 is a device that enables locking and unlocking of a door based on an authentication key that can be processed as digital data, such as alphanumeric characters that can be input by information input means such as a touch panel, and is not necessarily a physical key. Is one that does not require.

In addition, in the present embodiment, in addition to a normally used authentication key (hereinafter, a normally used authentication key may be referred to as a “master key”), a temporarily usable authentication key (hereinafter, “temporary key”) may be used. It is envisaged that the authentication key used for the purpose will be called "one-time key").
An example of a specific scene will be described with reference to FIG. A user A, such as a resident who has a master key for the door of the residence, requests the management server 2 to issue a one-time key in order to give the one-time key to the user B who temporarily enters the residence. In response to this, the management server 2 issues a one-time key and notifies the user A of the one-time key. The user A who has received the one-time key notifies the user B of this, so that the user B uses the one-time key to lock and unlock the door.

<Functional configuration>
The electric lock device 1 according to the first embodiment of the present invention will be described in detail.
As illustrated in FIG. 2, the electric lock device 1 includes an authentication information storage unit 11 including an arithmetic device such as a CPU (Central Processing Unit) and a storage device such as a RAM (Random Access Memory) or a ROM (Read Only Memory). A functional unit including a determination processing unit 12, a synchronization processing unit 13, an authentication processing unit 14, an input/output control unit 15, an unlocking control unit 16, and a communication processing unit 17 is configured. The physical mechanism includes an input/output unit 1A, a locking/unlocking mechanism 1B, and a driving power supply 1C.

Further, the electric lock device 1 is configured to be communicable with the management server 2 via the network NW.
Here, the network NW in which the electric lock device 1 communicates with the management server 2 is an LPWA (Low Power Wide Area) communication network NW in which a wireless station serves as a base station.

The authentication information storage unit 11 is a storage unit that stores an authentication code forming an authentication key, and the authentication key having the authentication code stored in the authentication information storage unit 11 locks and unlocks the electric lock device 1. It is recognized as an authentication key that has the proper authority to operate.
Here, the authentication code is information for authenticating the right to lock and unlock, and as described later, the authentication code may be the authentication key itself (in the case of a "master key") or the authentication code may be authenticated. There is a case where a part of the key is configured (a case of "one-time key"), but the authentication code stored in the authentication information storage unit 11 is not necessarily one, and a plurality of authentication codes are stored depending on the situation.

As described above, the authentication key includes the master key and the one-time key, but the master key is composed only of the authentication code for authenticating the authority to lock and unlock the door, and this authentication code is stored in the authentication information storage unit 11. Remembered.
On the other hand, the one-time key is composed of an authentication code and a synchronization instruction code for instructing the electric lock device 1 to synchronize with the management server 2. For this one-time key, the authentication code excluding the synchronization instruction code is stored in the authentication information storage unit 11.
The master key authentication code and the one-time key authentication code are usually different from each other.

When the authentication key is input to the electric lock device 1, the determination processing unit 12 determines whether or not the authentication key includes a synchronization instruction code. In this process, it is possible to determine whether or not the authentication instruction code is included in the authentication key by separately holding the synchronization instruction code in the reference table and referring to it.

As a result of the determination processing by the determination processing unit 12, the synchronization processing unit 13 performs synchronization with the management server 2 when the authentication key includes the synchronization instruction code, and the authentication information storage unit 21 on the management server 2 side. A process of updating the authentication code stored in the authentication information storage unit 11 is executed based on the information of 1. As a result, the authentication code included in the one-time key is authenticated based on the latest authentication code registered in the management server 2.
In the synchronization processing, it is possible to update only the one-time key authentication code, or to update all the authentication codes stored in the authentication information storage unit 11 of the electric lock device 1. Can also Further, not only when the one-time key including the synchronization instruction code is input, the synchronization information code can be input independently or the synchronization instruction means provided separately can synchronize the authentication information storage unit 11. May be.

The authentication processing unit 14 refers to the authentication information storage unit 11 and executes the authentication process of the authentication code included in the authentication key.
As described above, since the master key is the authentication code itself, if the authentication key is the master key, whether the authentication code as the master key matches the authentication code stored in the authentication information storage unit 11 or not. To be determined.
On the other hand, since the one-time key is composed of the synchronization instruction code and the authentication code, when the authentication key is the one-time key, after the synchronization processing is performed by the synchronization processing unit 13, the authentication code of the one-time key is used. It is discriminated whether or not the part of is coincident with the authentication code stored in the authentication information storage unit 11.

The input/output control unit 15 controls the input/output unit 1A to execute input and output of various data. Specifically, it controls the input/output unit 1A to accept the input of the authentication key and output the authentication result.

The lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door according to the authentication result based on the authentication key.

The communication processing unit 17 is a processing unit for executing communication with the management server 2 via the network NW.

The input/output unit 1A is realized by a touch panel type display or the like that receives and outputs various data based on a control signal from the input/output control unit 15.
In the present embodiment shown in FIG. 1, an example in which the input/output unit 1A is realized by a touch panel display is shown, but the present invention is not limited to this, and it is realized by an input processing unit such as a numeric keypad and an output processing unit such as a liquid crystal display. You can also do it.

The locking/unlocking mechanism 1B is a mechanism for locking/unlocking the door based on a control signal from the locking/unlocking control unit 16, and is configured by a drive device such as a motor or a solenoid and a lock such as a dead bolt.

The drive power supply 1C is a power supply for driving each functional unit and mechanism, and is configured by a battery such as a button battery or a dry battery that is used by being incorporated in the electric lock device 1.

The electric lock device 1 appropriately includes the functions and mechanisms included in the known electric lock device 1 in addition to the above-described functional units and mechanisms.

The management server 2 is a device that issues and manages an authentication code that authenticates the authority to lock and unlock the door, and is configured to be communicable with the electric lock device 1 and the user terminal 3 via the network NW.
The management server 2 includes a CPU (Central Processing Unit) or other computing device, a RAM (Random Access Memory) or ROM (Read Only Memory), a hard disk drive (HDD) or other storage device, and the authentication information storage unit 21 and the issuing process. A functional unit including the unit 22, the setting processing unit 23, the determination processing unit 24, and the communication processing unit 25 is configured.

The authentication information storage unit 21 is a storage unit that stores an authentication code that constitutes an authentication key.
In the authentication information storage unit 21, as shown in FIG. 4, for each identification information for identifying the electric lock device 1, the authentication code issued to each electric lock device 1 and each authentication code are set. Revocation conditions are stored in association with each other.
This authentication information storage unit 11 stores all authentication codes that are valid for locking and unlocking each electric lock device 1, and when the electric lock device 1 is synchronized by a request, this authentication information is stored. All the authentication codes stored in the storage unit 11 are reflected in the authentication information storage unit 11.

The revocation condition relates to the condition for revoking the authentication code, and if the revocation condition is satisfied, the authentication code will be revoked. On the contrary, unless the revocation condition is satisfied, the authentication code is valid.
The revocation condition includes, for example, an expiration date and the number of times of validity, and the authentication code for which the revocation condition is set is revoked according to the revocation condition after a certain period of time or a certain number of times of use.

As described in the authentication information storage unit 11 of the electric lock device 1, the authentication key has a master key and a one-time key. In the case of the master key, the authentication code, which is the master key itself, stores the authentication information. It is stored in the unit 21. On the other hand, in the case of the one-time key, the authentication code excluding the synchronization instruction code is stored in the authentication information storage unit 21.

The issuance processing unit 22 issues the authentication code that constitutes the authentication key, and also executes the processing that issues the authentication key configured by the authentication code and the synchronization instruction code.

The setting processing unit 23 sets a predetermined revocation condition for the authentication code, determines whether the set revocation condition is satisfied, and revokes the authentication code having the revocation condition.
It should be noted that the revocation condition is, for example, accepted together with the one-time key issuance request from the user, and the revocation condition is set in the authentication code that constitutes the one-time key issued by the issuance processing unit 22.
When the revocation condition is the number of times of use, the number of times of use is counted each time the information related to the use of the one-time key is received from the electric lock device 1 or each time the synchronization is accepted, and the predetermined number of times of use is reached. Sometimes revokes an authorization code.
The revocation of the authentication code may be to delete the revoked authentication code from the authentication information storage unit 21, or to associate the revoked authentication code with the revocation information so that it cannot be used for authentication. May be

The determination processing unit 24 refers to the revocation condition set in the authentication code and determines whether the revocation condition is satisfied. The determination of whether or not the revocation condition is provided may be performed at any time, or may be performed at the timing when synchronization is requested by the electric lock device 1.

The communication processing unit 25 is a processing unit that enables data transmission/reception between the electric lock device 1 and the user terminal 3 via the network NW.
As a result, it is possible to perform synchronization with the electric lock device 1, receive a one-time key issue request with the user terminal 3, and notify the issued one-time key.

The user terminal 3 is a terminal used by a user who uses the authentication key and requests the management server 2 to issue a one-time key. The user terminal 3 is realized by, for example, a portable terminal such as a mobile phone capable of transmitting and receiving data, a tablet terminal, a so-called personal computer, or the like.

The network NW with which the user terminal 3 communicates with the management server 2 is, for example, the Internet.
The user uses the user terminal 3 to request the management server 2 to issue a one-time key and receive the one-time key from the management server 2.

<Process flow>
Next, a flow of a series of processing executed in the system configured by the electric lock device 1, the management server 2, and the user terminal 3 according to the present embodiment will be described.
First, the flow when the one-time key is issued will be described with reference to FIG.
The user accesses the management server 2 through the user terminal 3 and requests the issuance of the one-time key used for the predetermined electric lock device 1 (S101).
In the issuance request of the one-time key, in addition to the identification information for specifying the electric lock device 1, the revocation condition arbitrarily set in the one-time key is notified.

In response to this, the management server 2 issues an authentication code by the issue processing unit 22 (S102), and registers the issued authentication code in the authentication information storage unit 21 (S103). At this time, when the user requests the setting of the revocation condition, the setting processing unit 23 sets the revocation condition in the issued authentication code and registers it in the authentication information storage unit 21.

A synchronization instruction code is attached to the issued authentication code, and the management server 2 notifies the user terminal 3 as a one-time key (S104).

In this example, the user terminal 3 requests the management server 2 to issue a one-time key, but the present invention is not limited to this, and the electric lock device 1 issues a one-time key to the management server 2. Can be requested.
In this case, when a one-time key issuance request or a revocation condition is input from the input/output unit 1A of the electric lock device 1, this is transmitted to the management server 2 together with the identification information of the electric lock device 1, and in the management server 2. The issued one-time key is notified to the electric lock device 1.

Further, regardless of this example, at the time of requesting issuance of the one-time key, the user designates the user terminal 3 of another user as the recipient of the one-time key, and the one-time key is assigned to the user terminal 3 of the other user. It is also possible to notify. In the example of FIG. 2, the user A sends the information of the user B as the recipient of the one-time key to the management server 2 when issuing the one-time key, and the management server 2 directly sends the one-time key to the user B. Can be notified.

In this embodiment, the issuing processing unit 22 of the management server 2 issues the authentication code, combines the synchronization instruction code with the authentication code to generate a one-time key, and notifies the user of this. .. On the other hand, in another embodiment, only the authentication code is notified from the management server 2 to the user terminal 3, and the user who receives the notification of the authentication code for the one-time key from the management server 2 himself, A one-time key may be created by combining a synchronization instruction code with the authentication code.

Subsequently, in the electric lock device 1 according to the present embodiment, a flow of a series of processes executed when the authentication key is authenticated and the door is locked and unlocked will be described with reference to FIG. 6.
The electric lock device 1 receives the input of the authentication key from the user together with the door lock/unlock request through the input/output unit 1A (S201).

The discrimination processing unit 12 discriminates whether or not the synchronization instruction code is included in the authentication key (S202).
As a result, if the synchronization instruction code is included, the synchronization processing unit 13 executes synchronization with the management server 2 (S203). In executing the synchronization, the electric lock device 1 transmits a synchronization request together with the identification information of the electric lock device 1 to the management server 2, and the management server 2 having received the synchronization request refers to the authentication information storage unit 21, The authentication code associated with the electric lock device 1 identified by the corresponding identification information is transmitted to the electric lock device 1 (S204). As a result, the authentication code in the authentication information storage unit 11 is updated based on the authentication code transmitted from the management server 2 to the electric lock device 1 (S205).

After the authentication code is updated by synchronization, or when it is determined in step S202 that the synchronization instruction code is not included in the authentication key, the authentication processing unit 14 executes the authentication code authentication process ( S206). That is, it is determined whether or not the authentication code forming the input authentication key matches the authentication code registered in the authentication information storage unit 11 and proves the legitimate locking/unlocking authority.

When the authentication fails as a result of the authentication, the process ends by displaying the error information on the input/output unit 1A without performing the locking/unlocking operation (S207).
On the other hand, when the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S208).

Next, in the present embodiment, a flow of processing when it is determined that the authentication code has a revocation condition is described with reference to FIG. 7.
The determination processing unit 24 refers to the revocation condition set in the authentication code and determines whether the revocation condition is satisfied (S301). The determination of whether or not the revocation condition is provided may be performed at any time, or may be performed at the timing when synchronization is requested by the electric lock device 1.

As a result, when it is determined that the authentication code has the revocation condition, the setting processing unit 23 revokes the authentication code having the revocation condition (S302).
When there is a request for locking/unlocking based on the revoked authentication code due to the revocation of the authentication code, this can be regarded as invalid and the locking/unlocking can be prevented.

According to the electric lock device 1 according to the present embodiment described above, in the authentication of the authentication key in the electric lock device 1, the synchronization with the management server 2 is performed only when the authentication request is made by the one-time key having the synchronization instruction code. Since the process is executed, consumption of the driving power source 1C of the electric lock device 1 can be suppressed.

Although the authentication code is stored in the authentication information storage units 11 and 21 in the present embodiment, the present invention is not limited to this, and the authentication key may be stored. That is, as the one-time key, a combination of the synchronization instruction code and the authentication code may be stored in the authentication information storage units 11 and 21, and in this case, the authentication processing unit 14 performs the one-time key authentication. , Authenticate the authentication key with the synchronization instruction code and the authentication code combined.
In addition, such various pattern settings are, for example, preset, specified by the type of the synchronization instruction code, and registered in the electric lock device 1 side when an operation is next input from the management server 2 during the first synchronization. There is a method of making it.

Next, the electric lock device 4 according to the second embodiment of the present invention will be described.
In this example, the electric lock device 4 determines whether the revocation condition set in the authentication code forming the one-time key is satisfied.
As shown in FIG. 8, the electric lock device 4 according to such an example is similar to the electric lock device 1 according to the first embodiment, and includes the authentication information storage unit 11, the determination processing unit 12, the synchronization processing unit 13, In addition to the functional unit including the authentication processing unit 14, the input/output control unit 15, the locking/unlocking control unit 16, and the communication processing unit 17, the input/output unit 1A, the locking/unlocking mechanism 1B, and the driving power supply 1C are provided. A setting processing unit 18 and a judgment processing unit 19 are provided.

The setting processing unit 18 according to the present embodiment determines that the revocation condition set for the authentication code is provided, and revokes the authentication code provided with the revocation condition.
When the revocation condition is the number of times of use, the number of times of use is counted each time the one-time key is used, and the authentication code is revoked when the predetermined number of times of use is reached.
The revocation of the authentication code may be to delete the revoked authentication code from the authentication information storage unit 11, or associate the revoked authentication code with the revocation information so that it cannot be used for authentication. It may be one.

The determination processing unit 19 refers to the revocation condition set in the authentication code and determines whether the revocation condition is satisfied. The determination of whether or not the revocation condition is provided may be performed at any time, or may be performed at the timing when the user requests the locking and unlocking.

In the present embodiment, the authentication information storage unit 11 included in the electric lock device 1 has the authentication code issued to the electric lock device 1 and the revocation set in the authentication code, as shown in FIG. The conditions are stored in association with each other.

In the electric lock device 1 according to the present embodiment having such a configuration, the revocation condition is determined by the electric lock device 1 side, and therefore, the locking and unlocking using the one-time key is performed only for the first time. For example, the subsequent management of the one-time key is performed by the electric lock device 1. Therefore, after the second authentication request, it is not always necessary to perform the authentication after the synchronization. Thus, in the authentication by the authentication processing unit 14, after the second authentication request, only the authentication code excluding the synchronization instruction code is accepted, and the authentication code stored in the authentication information storage unit 11 is authenticated. According to this, the load of the synchronization processing is reduced, and the consumption of the driving power supply 1C can be further suppressed.

Next, the electric lock device 5 according to the third embodiment of the present invention will be described.
In this example, when the one-time key is input, whether or not the authentication code excluding the synchronization instruction code from the one-time key is registered by referring to the authentication information storage unit 11 and is in a valid state. If it has been registered, it is locked and unlocked without synchronization. On the other hand, when it is not registered in the valid state, the synchronization processing is executed as usual, and then the authentication processing by the authentication processing unit 14 is executed. As a result, with respect to the authentication request by the one-time key, the synchronization can be executed only when the synchronization is required.
Note that this example will be described as a modification of the electric lock device 4 according to the second embodiment described above, and unless otherwise specified, the electric lock device 5 according to the present embodiment is the second lock device. A functional unit similar to that of the electric lock device 4 according to the embodiment is provided.

In the electric lock device 5 of this example, when the authentication key input is accepted, the authentication processing unit 14 refers to the authentication information storage unit 11 regardless of whether the authentication key is a master key or a one-time key. Then, the authentication process of the authentication code included in the authentication key is executed. That is, in this example, even if the authentication key that has received the input is the one-time key including the synchronization instruction code, authentication is first performed based on the authentication code.

In addition, the discrimination processing unit 12 in this example discriminates whether or not the synchronization instruction code is included in the authentication key when the authentication fails as a result of the authentication code authentication by the authentication processing unit 14. As a result, when it is determined that the authentication key that has failed the authentication of the authentication code includes the synchronization instruction code, once the synchronization is performed by the synchronization processing unit 13, the authentication processing by the authentication processing unit 14 is performed again. Is executed. On the other hand, if it is determined that the authentication key that has failed the authentication of the authentication code does not include the synchronization instruction code, the input authentication key does not have the proper authority for locking and unlocking. The process ends without locking and unlocking.

Subsequently, in the electric lock device 5 according to the present embodiment, a flow of a series of processes executed when the authentication key is authenticated and the door is locked and unlocked will be described with reference to FIG. 10.
The electric lock device 1 receives an input of an authentication key together with a door lock/unlock request from the user through the input/output unit 1A (S401).

In response to this, the authentication processing unit 14 executes the authentication processing of the authentication code included in the authentication key (S402). At this time, even if the authentication key that has received the input is the one-time key including the synchronization instruction code, the authentication is first performed based on the authentication code.
As a result, when the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S410).

If the result of the authentication processing in S402 is that the authentication has failed, the determination processing unit 12 determines whether or not the synchronization key is included in the authentication key (S403).
As a result, if the synchronization instruction code is not included, the error information is displayed by the input/output unit 1A without performing the locking/unlocking operation based on the authentication result of the authentication failure shown in S402. Then, the process ends (S404).

On the other hand, if the synchronization instruction code is included, the synchronization processing unit 13 executes synchronization with the management server 2 (S405). In executing the synchronization, the electric lock device 5 transmits a synchronization request to the management server 2 together with the identification information of the electric lock device 5, and the management server 2 receiving this request refers to the authentication information storage unit 21, The authentication code associated with the electric lock device 5 identified by the corresponding identification information is transmitted to the electric lock device 5 (S406). As a result, the authentication code in the authentication information storage unit 11 is updated based on the authentication code transmitted from the management server 2 to the electric lock device 5 (S407).

When the authentication code is updated by the synchronization processing, the authentication processing unit 14 again executes the authentication processing based on the authentication code included in the authentication key (S408).
If the authentication fails as a result of the authentication, the process ends by displaying the error information on the input/output unit 1A without performing the locking/unlocking operation (S409).
On the other hand, when the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S410).

According to the electric lock device 5 according to the present embodiment, even when the input of the one-time key including the synchronization instruction code is accepted, the synchronization is executed only when the synchronization is necessary, so that the load of the synchronization process is reduced. The consumption of the driving power supply 1C can be further suppressed.

Electric lock device.

Next, an electric lock device 6 according to the fourth embodiment of the present invention will be described.
In this example, both the master key and the one-time key are composed of only the authentication code, and the authentication key does not include the synchronization instruction code. Therefore, unlike the above-described embodiment, the one-time key does not include the synchronization instruction code, and all the authentication keys issued by the management server 2 are composed of only the authentication code. Then, the synchronization is performed by the electric lock device 6 based on a predetermined condition.

As shown in FIG. 11, the electric lock device 6 according to the present embodiment is similar to the electric lock device 4 according to the second embodiment in that it includes an authentication information storage unit 11, a synchronization processing unit 13, an authentication processing unit 14, and an input unit. A functional unit including an output control unit 15, a locking/unlocking control unit 16, a communication processing unit 17, a setting processing unit 18, and a determination processing unit 19, an input/output unit 1A, a locking/unlocking mechanism 1B, and a driving power supply 1C. Although the mechanism is provided, the discrimination processing unit 12 provided in the electric lock device 1 is not provided.
Note that each functional unit has the same function as each functional unit of the electric lock device 4 according to the second embodiment, unless otherwise specified.

In the present embodiment, the synchronization processing unit 13 executes the synchronization process with the management server 2 when the authentication fails as a result of the authentication performed on the input authentication key.
That is, in this example, the authentication is performed once before the synchronization, and when the authentication fails, the authentication information storage unit 11 is updated by the synchronization and the authentication is performed again, so that the synchronization process is performed each time the authentication key is input. I try not to do it.

Subsequently, in the electric lock device 6 according to the present embodiment, a flow of a series of processes executed when the authentication key is authenticated and the door is locked and unlocked will be described with reference to FIG. 12.
The electric lock device 6 receives the input of the authentication key from the user together with the door locking/unlocking request through the input/output unit 1A (S501).

In response to this, the authentication processing unit 14 executes the authentication processing of the authentication code forming the authentication key (S502).
As a result, when the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S508).

As a result of the authentication processing in S502, if the authentication fails, the synchronization processing unit 13 executes synchronization with the management server 2 (S503). In executing the synchronization, the electric lock device 6 transmits a synchronization request to the management server 2 together with the identification information of the electric lock device 6, and the management server 2 that receives the synchronization request refers to the authentication information storage unit 21, The authentication code associated with the electric lock device 6 identified by the corresponding identification information is transmitted to the electric lock device 6 (S504). As a result, the authentication code in the authentication information storage unit 11 is updated based on the authentication code transmitted from the management server 2 to the electric lock device 6 (S505).

When the authentication code is updated by the synchronization processing, the authentication processing unit 14 again executes the authentication processing based on the authentication code forming the authentication key (S506).
When the authentication fails as a result of the authentication, the process ends by displaying the error information on the input/output unit 1A without performing the locking/unlocking operation (S507).
On the other hand, when the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S508).

According to the electric lock device 6 according to the present embodiment described above, since the latest authentication key is confirmed by synchronizing with the management server 2 only when the authentication fails, the load of the synchronization process is also reduced. It is possible to suppress the consumption of the driving power source 1C. Further, since the one-time key does not include the synchronization instruction code, there is a complication when the management server 2 issues only the authentication code and the user adds the synchronization instruction code to the one-time key when issuing the one-time key. Not convenient.

Electric lock device.

Next, an electric lock device 7 according to a fifth embodiment of the present invention will be described.
In this example, the one-time key authentication process is executed on the management server 8 side.
As shown in FIG. 10, the electric lock device 7 according to such an example, like the electric lock device 1 according to the first embodiment, includes an authentication information storage unit 11, a determination processing unit 12, an authentication processing unit 14, The electric lock device 1 includes a functional unit including an input/output control unit 15, a locking/unlocking control unit 16, and a communication processing unit 17, and a mechanism including an input/output unit 1A, a locking/unlocking mechanism 1B, and a driving power supply 1C. Does not include the synchronization processing unit 13.
On the other hand, the management server 8 includes an authentication information storage unit 21, an issuance processing unit 22, a setting processing unit 23, a determination processing unit 24, and a communication processing unit 25, as well as the management server 2 in the first embodiment. The processing unit 26 is provided.

The authentication processing unit 26 executes the authentication process by referring to the authentication information storage unit 21 based on the one-time key received from the electric lock device 1 together with the authentication request or the authentication code included in the one-time key.
In the first and second embodiments, the one-time key is composed of the synchronization instruction code and the authentication code, but in the present embodiment, instead of the synchronization instruction code, the authentication requesting the management server 2 is authenticated. The request code together with the authorization code constitutes the one-time key. With such a one-time key configuration, the electric lock device 7, which has received the input of the one-time key together with the lock/unlock request, requests the management server 8 for authentication by the one-time key.

When the authentication key is input to the electric lock device 1, the determination processing unit 12 in this example determines whether or not the authentication key includes an authentication request code. In this process, it is possible to determine whether or not the authentication request code is included in the authentication key by separately holding the authentication request code in the reference table and referring to the table.

Subsequently, a flow of a series of processes when the authentication key is authenticated by the electric lock device 7 and the management server 8 according to the present embodiment will be described with reference to FIG.
The electric lock device 7 receives the input of the authentication key from the user together with the door lock/unlock request through the input/output unit 1A (S601).

The discrimination processing unit 12 discriminates whether or not the authentication request code is included in the authentication key (S602).
As a result, if the authentication request code is included, the communication processing unit 17 transmits the authentication request and the authentication key to the management server 8 (S603).
In response to this, the management server 8 refers to the authentication information storage unit 21 by the authentication processing unit 26, executes the authentication processing of the authentication key (S604), and sends the result to the electric lock device 7 ( S605).

The electric lock device 7, which has received the authentication result from the management server 8, executes processing according to the authentication result (S606). That is, if the authentication result indicates successful authentication, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S607). On the other hand, if the authentication result indicates the authentication failure, the error information is displayed by the input/output unit 1A without performing the locking/unlocking operation (S609).

Further, in S602, when it is determined that there is no authentication request code as a result of determining the presence or absence of the authentication request code, the authentication processing unit 14 refers to the authentication information storage unit 11 and inputs the input authentication key. The authentication process is executed (S608).
When the authentication fails as a result of the authentication, the process ends by displaying the error information on the input/output unit 1A without performing the locking/unlocking operation (S609).
On the other hand, if the authentication is successful, the lock/unlock control unit 16 controls the lock/unlock mechanism 1B to lock/unlock the door requested by the user (S607).

According to the electric lock device 7 according to the present embodiment described above, the management server 8 side executes the authentication process, and the management server 8 is connected only when the authentication request is made by the one-time key including the authentication request code. Since the synchronization process is executed, consumption of the driving power supply 1C of the electric lock device 7 can be suppressed.

In the above-described embodiment of the present invention, the input of the authentication key is performed by the information input means such as the touch panel, but the present invention is not limited to this, and the authentication key can be used in any of the first to fifth embodiments. Can be recorded in an IC card or the like, and the electronic lock device 1 can read this to be authenticated.

Further, the above-described embodiment of the present invention can be changed to any of the first to fifth embodiments by setting, for example. Further, the setting may be changed according to a user's instruction, or the management servers 2 and 8 may be changed according to the matching of a predetermined condition.
Further, the functions and configurations of the respective embodiments can be partially or entirely applied to other embodiments by appropriate design as long as there is no contradiction in processing.

In the above-described embodiment of the present invention, the electric lock device 1, 4, 5, 6, 7 or the management server 8 is provided with the authentication function and the function of determining the revocation condition. Except for the physical mechanism required to lock and unlock the door, the software resources that execute the processes required to carry out the present invention are distributed and held in a plurality of devices, or aggregated in a separately provided device. It can also be done. For example, the door is provided with only a physical mechanism such as the locking/unlocking mechanism 1B, and an external device provided separately from such a physical mechanism (unlike the management server, (Attached separately) can be provided with an authentication function and other processing functions.
