  The drive unit 35 drives the lock 36 of the door 3 of the facility 2 to unlock and lock the door 3. The electric lock storage unit 31 stores first information updated under the first update condition and second information updated under a second update condition different from the first update condition. The first information includes a first password, and the second information includes a second password. However, the first information may include a first identifier in addition to the first password. Similarly, the second information may include a second identifier in addition to the second password.

  The control unit 32 controls the drive unit 35 in response to an unlocking request or locking request for the door 3 received from the information terminal device 40. The information terminal device 40 is described on the assumption that it is a portable terminal device, but it may be an IC card, for example.

  The control unit 32 is configured to receive a request for unlocking the door 3 from the information terminal device 40 and cause the drive unit 35 to automatically lock the door 3 when a specific condition is satisfied. Yes. The specific condition includes that the key information received from the information terminal device 40 as the unlocking request matches either one of the first information and the second information. In the following description, receiving the locking request and locking the door 3 is called “normal locking”, and “automatically locking the door 3 without receiving the locking request” is called “automatic locking”. Sometimes called “locked”.

  Moreover, the electric lock system 1 of this embodiment is provided with the electric lock apparatus 30 and the server 10, as shown to FIG. 1A. The server 10 updates the first information (first password) and the second information (second password) of the electric lock device 30 and sends the key information to the information terminal device 40 in response to a request from the information terminal device 40. Output. In the present embodiment, it is assumed that the server 10 is provided outside the facility 2, for example, a security company.

  In the present embodiment, as shown in FIG. 1A, it is assumed that the electric lock system 1 further includes a controller 20, and the controller 20 performs regular communication with the electric lock device 30 and the server 10. In this case, the controller 20 is provided in the facility 2 in which the electric lock device 30 is provided. However, the controller 20 is not essential as a component of the electric lock system 1. That is, the server 10 and the electric lock device 30 may be configured to perform direct communication without using the controller 20.

(2) Details (2.1) Electric Lock System As shown in FIG. 1A, the electric lock system 1 includes a server 10, a controller 20, an electric lock device 30, and an information terminal device 40. The electric lock device 30 is provided on the door 3 of the facility 2. The controller 20 is provided in the facility 2. The facility 2 is, for example, a building such as a detached house, each dwelling unit of an apartment house, an office, a factory, or a store. In the present embodiment, the facility 2 will be described assuming a detached rental house as an example. The server 10 is provided outside the facility 2, for example, a security company.

  The electric lock device 30 performs an unlocking process for unlocking the lock 36 of the door 3 of the facility 2 and a locking process for locking the lock 36. In the present embodiment, the electric lock device 30 further performs an automatic locking process.

  The server 10 issues and manages information used for the unlocking process and the locking process performed by the electric lock device 30. There are two types of information used for the unlocking process and the locking process. The first is a first password (first information), and the second is a second password (second information). The first password is used when a person who wants to visit a facility that has not yet moved in (introspection) (hereinafter simply referred to as “visitor”) unlocks the door when entering the facility, or when the person leaves the facility. Used for door locking. In short, the first password is used for a visitor to use the facility temporarily. On the other hand, the second password is used by a long-term user (for example, a resident) who uses the facility for a long time.

  The first password is updated with the first update condition. The second password is updated under a second update condition that is different from the first update condition. In the present embodiment, the first update condition is, for example, that a first predetermined period (for example, one day) elapses from the time when the first password in the electric lock storage unit 31 was updated last time. is there.

  However, as an option of the first update condition, when the information terminal device 40 acquires key information from the server 10, a second predetermined period (for example, 1-2 days) has elapsed from the acquired time. You may update from. In this case, for example, even if the information terminal device 40 obtains key information from the server 10 immediately before the regular update time every day, the first password in the electric lock device 30 is already used when the key information is actually used. Can be prevented from being updated to a different first password.

  In any case, the first password is periodically updated with the passage of time as a trigger. On the other hand, the second password is updated using, for example, an application for moving into the facility 2 (for example, a lease contract) or an application for leaving the facility 2 (cancellation).

  As shown in FIG. 1A, the server 10 can communicate with the information terminal device 40 via a network 4 such as the Internet. The information terminal device 40 is a portable terminal device, such as a smart phone or a tablet terminal.

  The electric lock device 30 can perform short-range wireless communication with the information terminal device 40. The information terminal device 40 can request the electric lock device 30 to perform unlocking processing and locking processing. When receiving the request for the unlocking process from the information terminal device 40, the electric lock device 30 performs the unlocking process. Then, the electric lock device 30 unlocks the lock 36 of the door 3 according to the processing result. In addition, when the electric lock device 30 receives a lock processing request from the information terminal device 40, the electric lock device 30 performs the lock processing. Then, the electric lock device 30 locks the lock 36 of the door 3 according to the processing result.

  The controller 20 can communicate with the server 10 via the network 4 and can communicate with the electric lock device 30 by low power radio. That is, communication between the server 10 and the electric lock device 30 is performed via the controller 20.

  The controller 20 periodically communicates with the server 10 (first periodic communication). The first regular communication is performed, for example, once a day at a predetermined time. Further, the controller 20 periodically communicates with the electric lock device 30 (second regular communication). For example, the controller 20 performs the second regular communication every hour.

(2.1.1) Server Hereinafter, the configuration of the server 10 will be described in detail.

  When receiving confirmation request information from the controller 20 during the first regular communication, the server 10 transmits response information to the controller 20 as a response. As shown in FIG. 1A, the server 10 includes a server storage unit 11, a control unit 12, and a communication unit 13. The server 10 has a CPU (Central Processing Unit) and a memory. The function of the control unit 12 is realized by the CPU executing a program stored in the memory. Here, the program is recorded in advance in the memory of a computer. The program may be provided through a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.

  The server storage unit 11 is configured by an electrically rewritable nonvolatile semiconductor memory such as a flash memory. The server storage unit 11 stores a first password and a second password.

  As shown in FIG. 1, the control unit 12 includes an output unit 14, an issuing unit 15, and a timer 16 that measures time.

  In response to a request from the information terminal device 40, the output unit 14 outputs one of the first password and the second password stored in the server storage unit 11 to the information terminal device 40 as key information. For example, when the information terminal device 40 requests the first password, the key information including the first password is output to the information terminal device 40. When the information terminal device 40 requests the second password, the key information including the second password is output to the information terminal device 40.

  The issuing unit 15 issues a first password and a second password when starting operation of the electric lock system 1. Specifically, the issuing unit 15 generates a first password and a second password and stores them in the server storage unit 11 when the operation of the electric lock system 1 is started. The issuing unit 15 transmits the generated first password and second password to the electric lock device 30 via the communication unit 13 and the controller 20.

  Thereafter, the issuing unit 15 stores the first password stored in the server storage unit 11 and the electric lock device 30 during the first regular communication while the first password stored in the server storage unit 11 is not output to the information terminal device 40. 1 Update the password. For example, the issuing unit 15 generates a new first password during the first regular communication, and rewrites (updates) the first password stored in the server storage unit 11 with the new first password. The issuing unit 15 includes the generated new first password in the response information and transmits the response to the electric lock device 30 via the controller 20, and the first password stored in the electric lock storage unit 31 in the electric lock device 30 is transmitted. Update. In short, the issuing unit 15 performs the first regular communication every time a first predetermined period (for example, one day) elapses. At the same time, the first password in the electric lock device 30 is changed to a new first password. Updated. In other words, unless the output unit 14 outputs the first password to the information terminal device 40, the first password in the electric lock device 30 is automatically generated every time the first predetermined period elapses from the last updated time. Updated.

  On the other hand, the issuing unit 15 causes the timer 16 to start measuring when the output unit 14 outputs the first password to the information terminal device 40. The issuing unit 15 updates the first password when the timer 16 passes the second predetermined period (for example, 1-2 days). The timer 16 stops timing when the second predetermined period elapses, and returns the timing time to the initial value. Here, the second predetermined period is a period from the time when the output unit 14 outputs the first password to the information terminal device 40 to the predetermined time. The issuing unit 15 updates the first password stored in the server storage unit 11 and the electric lock device 30 at the timing of the first first regular communication after the second predetermined period has elapsed. The issuing unit 15 does not update the first password of the server storage unit 11 and the electric lock device 30 when the first regular communication is performed within the second predetermined period. Therefore, the first password is not included in the response information transmitted to the controller 20 within the second predetermined period.

  When the resident of the facility 2 moves out, the issuing unit 15 receives, from the information terminal device 40, the eviction information indicating the resident's withdrawal through the communication unit 13. When the issuing unit 15 receives the withdrawal information, the issuing unit 15 updates the second password stored in the server storage unit 11 and the electric lock device 30. For example, the issuing unit 15 generates a new second password, and rewrites (updates) the second password stored in the server storage unit 11 with the new second password. The issuing unit 15 transmits the generated second password to the electric lock device 30 via the communication unit 13 and the controller 20, and causes the electric lock device 30 to update the second password stored in the electric lock storage unit 31. . The issuing unit 15 transmits the generated second password to the electric lock device 30 via the communication unit 13 and the controller 20 by including the new second password in the response information during the first regular communication.

  The communication unit 13 is connected to the network 4 to enable communication between the server 10 and the information terminal device 40 and between the server 10 and the controller 20.

(2.1.2) Controller Hereinafter, the configuration of the controller 20 will be described in detail.

  As shown in FIG. 2, the controller 20 includes a first communication unit 21, a second communication unit 22, a power supply unit 23, a control unit 24, a battery 25, and a charging unit 26. The controller 20 has a CPU and a memory. The function of the control unit 24 is realized by the CPU executing a program stored in the memory. Here, the program is recorded in advance in the memory of a computer. The program may be provided through a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.

  The first communication unit 21 is a wireless module for communication with the server 10 and is controlled by the control unit 24. The first communication unit 21 has a first transmission function and a first reception function. The first transmission function is a function for transmitting information to the server 10 via the network 4. The first reception function is a function for receiving information from the server 10 via the network 4.

  The second communication unit 22 is a communication module for communication with the electric lock device 30 and is controlled by the control unit 24. The second communication unit 22 communicates with the electric lock device 30 using low-power wireless communication as a communication method. Due to the difference in communication method, the power consumption of the second communication unit 22 is smaller than the power consumption of the first communication unit 21.

  The power supply unit 23 is electrically connected to the battery 25 and the external power supply 5, and is configured to be able to generate an operating power supply regardless of whether power is supplied from either the battery 25 or the external power supply 5. The power supply unit 23 operates in any one of the first mode in which the operating power is generated with the power of the battery 25 and the second mode in which the operating power is generated with the power of the external power supply 5.

  Although not shown in FIG. 2, the first communication unit 21, the second communication unit 22, and the control unit 24 are electrically connected to the power supply unit 23 and generated by the power supply unit 23. The operation power supply provides power for operation of each part of the controller 20.

  The control unit 24 switches the operation mode of the power supply unit 23 between the first mode and the second mode in accordance with the supply state of power from the external power supply 5 to the power supply unit 23. For example, the control unit 24 sets the operation mode to the first mode when power is not supplied from the external power supply 5 to the power supply unit 23, and sets the operation mode to the second mode when power is supplied. Switch to mode. Thereby, for example, the controller 20 can operate in the first mode when the facility 2 is in an empty room (vacant house) state, and in the second mode otherwise.

  In the first mode, the control unit 24 is configured to cause the first communication unit 21 to perform a transmission operation and a reception operation at a timing at which the first regular communication is performed and a timing at which the first password is used. For example, when the current time is the time for performing the first regular communication, the control unit 24 activates the first communication unit 21 for a predetermined time (for example, one minute). In other time zones, the control unit 24 stops supplying power to the first communication unit 21. If the first password is used when the power supply is stopped, the control unit 24 activates the first communication unit 21 for a predetermined time (for example, one minute).

  When the response information received during the first regular communication includes the first password, the control unit 24 transmits the first update information to the electric lock device 30 via the second wireless unit 34. Here, the first update information is information indicating an instruction to update the first password stored in the electric lock device 30 and includes the first password included in the response information.

  When the second password is included in the response information received during the first regular communication, the control unit 24 transmits the second update information to the electric lock device 30 via the second wireless unit 34. Here, the second update information is information representing an instruction to update the second password stored in the electric lock device 30 and includes the second password included in the response information.

  In the first mode, the control unit 24 is configured to cause the second communication unit 22 to perform a transmission / reception operation and a reception operation at the timing of performing the second regular communication. For example, when the current time is the time for performing the second regular communication, the control unit 24 activates the second communication unit 22 for a predetermined time (for example, 5 seconds). In other time zones, the control unit 24 stops supplying power to the second communication unit 22.

  When updating the first password stored in the electric lock device 30, the control unit 24 transmits the first update information described above to the electric lock device 30 during the second regular communication. When updating the second password stored in the electric lock device 30, the control unit 24 transmits the second update information described above to the electric lock device 30 during the second regular communication.

  The control unit 24 operates in the second mode when the operation of the electric lock system 1 is started, and makes the first communication unit 21 operable. That is, the first communication unit 21 can receive the first password and the second password when the server 10 generates the first password and the second password and immediately transmits them. When the first communication unit 21 receives the first password and the second password at the start of operation of the electric lock system 1, the control unit 24 receives the received first password and second password via the second communication unit 22. It transmits to the electric lock device 30.

  The battery 25 is a secondary battery that is housed in the housing of the controller 20 and is charged by the power of the external power supply 5. The battery 25 is electrically connected to the external power source 5 via the charging unit 26. The charging unit 26 includes a rectifying / smoothing circuit and a DC / DC converter, and charges the battery 25 using power from the external power supply 5. The battery 25 is, for example, a lithium battery or a nickel / cadmium battery.

The electric lock device 30 has a CPU and a memory. The function of the control unit 32 is realized by the CPU executing a program stored in the memory. Here, the program is recorded in advance in the memory of a computer. The program may be provided through a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.

  The electric lock storage unit 31 is configured by an electrically rewritable nonvolatile semiconductor memory such as a flash memory. The electric lock storage unit 31 stores the first password and the second password output from the server 10.

  As shown in FIG. 1B, the control unit 32 includes a registration unit 32A, a reception unit 32B, a processing unit 32C, and a timer 32D.

  When the registration unit 32A receives the first password and the second password from the server 10 via the controller 20 and the first wireless unit 33 when the operation of the electric lock system 1 is started, the registration unit 32A receives the received first password and second password. Store in the storage unit 31.

  Upon receiving the first update information from the server 10 via the controller 20, the registration unit 32A rewrites (updates) the first password stored in the electric lock storage unit 31 with the first password included in the first update information. ). When the registration unit 32A receives the second update information from the controller 20, the registration unit 32A rewrites (updates) the second password stored in the electric lock storage unit 31 with the second password included in the second update information.

  The accepting unit 32B accepts an unlocking request (unlocking request information) for requesting the unlocking of the lock 36 of the door 3 from the information terminal device 40 via the second wireless unit 34. The unlocking request includes key information used for authentication for unlocking the lock 36 of the door 3. When receiving the unlocking request, the receiving unit 32B outputs the key information included in the unlocking request to the processing unit 32C.

  Further, the receiving unit 32B receives a locking request (locking request information) for requesting locking of the lock 36 of the door 3 from the information terminal device 40 via the second wireless unit 34. The lock request includes the same key information as the key information used for authentication for unlocking the lock 36 of the door 3. When receiving the locking request, the receiving unit 32B outputs the key information included in the locking request to the processing unit 32C.

  When the processing unit 32C receives an unlocking request (or locking request) from the information terminal device 40, the processing unit 32C uses the key information and the first password and the second password in the electric lock storage unit 31 to perform the unlocking process (or Locking process). The processing unit 32C determines whether the key information received from the information terminal device 40 matches either the first password or the second password in the electric lock storage unit 31. That is, the processing unit 32C performs authentication using the key information, the first password, and the second password.

  When it is determined that the key information matches one of the first password and the second password, that is, when it is determined that the authentication is successful, the processing unit 32C controls the drive unit 35 to unlock the lock 36 of the door 3. Or lock it.

  Specifically, when the unlocking request is received from the information terminal device 40, if the processing unit 32C determines that the authentication is successful, the control unit 32 indicates an instruction to unlock the lock 36 to the driving unit 35. An unlocking instruction is output (execution of unlocking). When determining that they do not match, that is, when determining that the authentication has failed, the processing unit 32C ends the unlocking process without outputting the unlocking instruction.

  If the processing unit 32C determines that the authentication is successful when receiving the locking request from the information terminal device 40, the control unit 32 outputs a locking instruction indicating an instruction to lock the lock 36 to the driving unit 35. (Locking execution). If it is determined that they do not match, that is, if it is determined that the authentication has failed, the processing unit 32C ends the locking process without outputting the locking instruction.

  When executing the unlocking process or the locking process, the processing unit 32C sends execution information indicating that the process has been executed to the server 10 via the first wireless unit 33 and the controller 20 regardless of the success or failure of the authentication. Send. Note that the server 10 may be configured to notify the user with information such as voice output or message display when acquiring information related to the authentication failure. In addition, the controller 20 or the electric lock device 30 itself may be configured to notify by voice output or message display according to the failure of authentication.

  When the unlocking request is received from the information terminal device 40 when the lock 36 of the door 3 is in the unlocked state, the processing unit 32C cancels the unlocking request and ends the unlocking process. At this time, the electric lock device 30 may be configured to perform voice output or message display for notifying the user who has made the request that the unlock request has been canceled. Further, when the lock part 36 of the door 3 is in the locked state, the processing unit 32C cancels the locking request and ends the locking process when receiving the locking request from the information terminal device 40. Also at this time, the electric lock device 30 may be configured to perform voice output or message display for notifying the user who has made the request that the lock request has been canceled.

  Furthermore, the processing unit 32C is configured to perform automatic locking. Specifically, the processing unit 32C is configured to receive the unlocking request from the information terminal device 40 and cause the driving unit 35 to automatically lock the door 3 when a specific condition is satisfied. Has been. In the present embodiment, the specific condition includes that the key information included in the unlock request received from the information terminal device 40 matches the first password in the electric lock storage unit 31. In other words, in this embodiment, as an example, it is assumed that the processing unit 32C does not perform automatic locking even when the key information included in the unlocking request received from the information terminal device 40 matches the second password. However, the processing unit 32C may be configured to perform automatic locking even when the key information included in the unlock request received from the information terminal device 40 matches the second password. In this way, the processing unit 32C receives the unlocking request from the information terminal device 40, and executes the locking of the door 3 even if the locking request is not received from the information terminal device 40 when a specific condition is satisfied. To do.

  Furthermore, in the present embodiment, the specific condition further includes that a certain period (for example, several hours) elapses from the time when the drive unit 35 unlocks the door 3 based on the key information. That is, the timing at which automatic locking is actually performed is not immediately after the door 3 is unlocked in response to the reception of the unlocking request and the success of the authentication, but for example, several hours later. The predetermined period is measured by the timer 32D of the control unit 32. Note that the controller 20 may be provided with the function of measuring the certain period.

  The first wireless unit 33 is a communication module for communication with the controller 20 and is controlled by the control unit 32. The first wireless unit 33 communicates with the controller 20 using low-power wireless communication as a communication method.

(2.2) Periodic Update of First Password Hereinafter, the operation of periodically updating the first password in the electric lock system 1 will be described with reference to FIG. 3 (Step 1 to Step S8). That is, the operation when the first password stored in the server storage unit 11 of the server 10 and the electric lock storage unit 31 of the electric lock device 30 is updated under the first update condition will be described.

  Here, the first update condition is that the first password is updated during the first regular communication performed once a day, for example, while the first password is not output from the server 10 to the information terminal device 40. Assume that. In short, the first update condition is that the first predetermined period Ta1 illustrated in FIG. 3 elapses.

  In the following description, it is assumed that the controller 20 transmits a confirmation request (confirmation request information) to the server 10. However, the configuration of the electric lock system 1 is not limited to this, and the server 10 may transmit a confirmation request to the controller 20.

  When it is time to perform the first regular communication, the controller 20 transmits a confirmation request to the server 10 (step S1).

  When the server 10 receives the confirmation request from the controller 20, the issuing unit 15 of the server 10 generates a new first password when the first password is not output to the information terminal device 40. The issuing unit 15 transmits response information including the generated new first password to the controller 20 (step S2). At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the generated new password. The controller 20 transmits the first update information including the first password included in the response information to the electric lock device 30 (step S3).

  When the registration unit 32A of the electric lock device 30 receives the first update information from the controller 20, the registration unit 32A updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S4).

  While the 1st password memorize | stored in the server memory | storage part 11 is not output to the information terminal device 40, the operation | movement similar to step S1-S4 is repeated (step S5-S8).

  In FIG. 3, the first predetermined period Ta1 is between time t1 (step S1) at which the controller 20 transmits a confirmation request to the server 10 and time t2 (step S5) at which the next confirmation request is transmitted. It is a period. However, since the period from step S1 to step S4 and the period from step S5 to step S8 are substantially the same, the first predetermined period Ta1 is updated (step S4) in the electric lock device 30. It can be said that it is the same as the period between the time and the time of the next update / update (step S8). In short, it can be said that the first password in the electric lock device 30 is automatically updated every time the first predetermined period Ta1 elapses from the last updated time.

  As described above, in the electric lock system 1, the key information including the first password is stored in both the server storage unit 11 and the electric lock storage unit 31 while the key information including the first password is not output (downloaded) to the information terminal device 40. One password is periodically updated every time the first predetermined period Ta1 elapses. For example, the first password is updated once a day. That is, it is stored in the server storage unit 11 and the electric lock storage unit 31 on the condition that the first predetermined period Ta1 has elapsed from the predetermined period, specifically, the time when the first password is updated. The first password is updated. Thereby, since the update is performed even while the first password is not output, the security is enhanced.

(2.3) Door Unlocking and Option Update of First Password Hereinafter, processing relating to unlocking of the door 3 in the electric lock device 30 will be described with reference to FIG. 3 (after step S9).

  Here, the option update of the first password in the electric lock system 1 will also be described. That is, the first password may be updated as described below in addition to the periodic update described in the column “(2.2) Periodic update of the first password”. In other words, as an option, when the information terminal device 40 acquires key information (first password) from the server 10 as an option, the second predetermined period Ta2 (see FIG. 3) is acquired from the acquisition time. Elapse may be included. In other words, when the information terminal device 40 acquires the key information from the server 10, the periodic update described in the above-mentioned column “(2.2) Periodic update of the first password” until the second predetermined period Ta2 elapses. May be temporarily stopped.

  First, the visitor uses the information terminal device 40 to access the server 10 and download key information (first password), for example. In this case, the information terminal device 40 transmits a request for the first password to the server 10 (step S9). When receiving the first password request from the information terminal device 40, the output unit 14 of the server 10 outputs the first password stored in the server storage unit 11 to the information terminal device 40 (step S10). At this time, the timer 16 starts counting time from the time t3 when the first password is output to the information terminal device 40.

  The controller 20 transmits a confirmation request when it is time to perform the first regular communication (step S11). The server 10 transmits response information to the controller 20 (step S12). At this time, the issuing unit 15 does not generate the first password because the time count of the timer 16 has not passed the second predetermined period Ta2. That is, the server 10 transmits response information that does not include the first password to the controller 20. Therefore, the controller 20 does not instruct the electric lock device 30 to update the first password. At this time, the first password stored in the server storage unit 11 is not updated either. Here, the second predetermined period Ta2 is a period from time t3 to time t4.

  Subsequently, the visitor unlocks the door 3 using the information terminal device 40 in front of the door 3 of the facility 2 in order to actually enter the facility 2. For example, the visitor makes a request to unlock the door 3 using the information terminal device 40. That is, the information terminal device 40 transmits an unlocking request to the electric lock device 30 (step S13). At this time, the information terminal device 40 includes the key information received in step S10 in the unlock request, and transmits the unlock request to the electric lock device 30.

  When receiving the unlock request, the processing unit 32C of the electric lock device 30 performs the unlocking process (step S14). Specifically, the processing unit 32C determines whether or not the key information included in the unlocking request matches either the first password or the second password stored in the electric lock storage unit 31. When the key information matches the first password or the second password in the electric lock storage unit 31, the processing unit 32C causes the drive unit 35 to unlock the lock 36. If the key information does not match any password in the electric lock storage unit 31, the electric lock device 30 notifies the user by voice output or message display.

  When executing the unlocking process, the processing unit 32C transmits execution information including the authentication result to the server 10 via the controller 20 regardless of the success or failure of the authentication (step S15). When the server 10 receives the information regarding the authentication failure, the server 10 notifies the user by voice output or message display.

  Thereafter, the controller 20 transmits a confirmation request to the server 10 when it is time to perform the first regular communication (step S16). The server 10 transmits response information to the controller 20 (step S17). At this time, the issuing unit 15 does not generate the first password because the time count of the timer 16 has not passed the second predetermined period Ta2.

  When it is time to perform the first regular communication, the controller 20 transmits a confirmation request to the server 10 (step S18).

  Here, the confirmation request is received only after the second predetermined period Ta2 has elapsed. The issuing unit 15 generates a new first password, and transmits response information including the generated new first password to the controller 20 (step S19). At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the generated new password. The controller 20 transmits the first update information including the first password included in the response information to the electric lock device 30 (step S20). Note that the timer 16 stops timing when the second predetermined period Ta2 elapses, and returns the timing to the initial value.

  When the registration unit 32A of the electric lock device 30 receives the first update information from the controller 20, the registration unit 32A updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S21).

  As described above, in the electric lock system 1, after the first password is output to the information terminal device 40, it is stored in the server storage unit 11 and the electric lock storage unit 31 until the second predetermined period Ta2 elapses. The first password is not updated. This prevents the visitor from changing the first password in the server storage unit 11 and the electric lock storage unit 31 due to periodic updates before using the acquired key information (first password). it can.

  The second predetermined period Ta2 may be set to include the time when the door 3 is actually unlocked using the key information (first password) within the period. That is, the second predetermined period Ta2 may be a total period of the first period and the second period. In this case, the first period is a period between the acquisition time when the information terminal device 40 acquires the key information from the server 10 and the time when the door 3 is unlocked. The second period is a period from when the door 3 is unlocked until a specific period elapses.

  Further, as another option, when the information terminal device 40 acquires key information (first password) from the server 10 as another option, the number of times of the first regular communication is counted from the acquisition time. The number of times may exceed a predetermined number of times. In short, instead of timing the second predetermined period Ta2, the number of first periodic communications may be counted.

(2.4) Update of Second Password In the electric lock system 1, as an example, the second password is updated with a resident who has rented a contract applying for (withdrawing from) the facility 2 as a trigger. That is, in the electric lock system 1, it is a second password update condition (second update condition) stored in the server storage unit 11 and the electric lock storage unit 31 that the resident of the facility 2 moves out. For example, when the resident of the facility 2 transmits the withdrawal information indicating the withdrawal at the time of leaving to the server 10 using the information terminal device 40, the server 10 uses the server storage unit 11 and the electric lock as a trigger when the withdrawal information is received. The second password stored in the device 30 is updated. Or, for example, when a leaser receives an application for removal from a resident, it instructs the terminal 10 to access the server 10 and update the second password stored in the server storage unit 11 and the electric lock device 30. Also good.

  On the other hand, the update condition (first update condition) of the first password is set to a predetermined cycle (for example, once a day) while the first password is not output to the information terminal device 40 as described above. The update condition of the first password after the first password is output to the information terminal device 40 is that the second predetermined period Ta2 has elapsed after the first password is output to the information terminal device 40. . Therefore, in this embodiment, it can be said that the update frequency of the first password is higher than the update frequency of the second password.

  The update condition of the second password may be that the resident has lost the information terminal device 40 holding the key information (second password) in addition to the resident leaving the facility 2. Alternatively, the update condition of the second password may be that the information terminal device 40 that holds the key information (second password) has failed. That is, the update condition of the second password may be that the resident cannot use the information terminal device 40. In this case, for example, when the renter receives an application for loss or failure of the information terminal device 40 from the resident, the server 10 is accessed by the terminal device and stored in the server storage unit 11 and the electric lock device 30. You may be instructed to update your password.

(2.5) Normal Locking of Door Hereinafter, processing related to normal locking of the door 3 in the electric lock device 30 will be described with reference to FIG. For the sake of convenience, description will be made from the case where a visitor who has already acquired (downloaded) key information makes an unlock request.

  First, in order to enter the facility 2, the visitor requests the door 3 to be unlocked by the information terminal device 40 in front of the door 3 of the facility 2. That is, the information terminal device 40 transmits an unlock request to the electric lock device 30 (corresponding to step S13 in FIG. 3).

  As shown in FIG. 4, the processing unit 32C of the electric lock device 30 receives the unlock request (step S30), and performs the unlock process (step S31). In the unlocking process, the processing unit 32C determines whether or not the key information included in the unlocking request matches either the first password or the second password stored in the electric lock storage unit 31. That is, the processing unit 32C performs authentication using the acquired key information and the first and second passwords (step S32).

  If it is determined that the authentication has succeeded (Yes in step S32), the processing unit 32C causes the drive unit 35 to unlock the lock 36 (step S33). On the other hand, when determining that the authentication has failed (No in step S32), the processing unit 32C finishes the unlocking process without causing the drive unit 35 to unlock the lock 36. Then, error processing is executed (step S34). As the error processing, for example, the electric lock device 30 notifies by voice output or message display.

  Note that, when the unlocking process is executed, the processing unit 32C transmits execution information including the authentication result to the server 10 via the controller 20 regardless of the success or failure of the authentication. When the server 10 receives the information regarding the authentication failure, the server 10 notifies the user by voice output or message display.

  Furthermore, the processing unit 32C starts the automatic locking process only when the acquired key information matches the first password in the electric lock storage unit 31 (Yes in step S34) (step S35). The automatic locking process will be described in the next column “(2.6) Automatic door locking”.

  On the other hand, when the acquired key information matches the second password instead of the first password (No in step S34), the processing unit 32C enters a state of waiting for reception of the locking request (step S36). If a locking request is received (Yes in step S36), the processing unit 32C performs a normal locking process (step S37).

  For example, after a visitor who has successfully unlocked the door 3 finishes the tour and goes out of the facility 2, the information terminal device 40 requests the locking of the door 3 without forgetting to lock the door 3. If it transmits to 30, locking processing will be started.

  In the locking process, the processing unit 32C determines whether or not the key information included in the locking request matches either the first password or the second password in the electric lock storage unit 31. That is, the processing unit 32C performs authentication using the acquired key information and the first and second passwords (step S38).

  When determining that the authentication is successful (Yes in step S38), the processing unit 32C causes the drive unit 35 to lock the lock 36 (step S39). On the other hand, when determining that the authentication has failed (No in step S38), the processing unit 32C ends the locking process without causing the driving unit 35 to lock the lock 36. Then, error processing is executed (step S40). As the error processing, for example, the electric lock device 30 notifies by voice output or message display.

  When executing the locking process, the processing unit 32C transmits execution information including the authentication result to the server 10 via the controller 20 regardless of the success or failure of the authentication. When the server 10 receives the information regarding the authentication failure, the server 10 notifies the user by voice output or message display.

(2.6) Automatic Locking of Door Hereinafter, processing related to automatic locking of the door 3 in the electric lock device 30 will be described with reference to FIG.

  The processing unit 32 </ b> C starts the automatic locking process only when the key information acquired as the unlock request matches the first password in the electric lock storage unit 31. Then, as illustrated in FIG. 5, the processing unit 32C causes the timer 32D to start measuring time (step S50).

  After starting the automatic locking process, the processing unit 32C waits for reception of a locking request (step S51). If the lock request is received before the elapse of a certain period (for example, several hours) by the timer 32D (Yes in step S51), the processing unit 32C ends the automatic locking process. Then, the process proceeds to a normal locking process (step S52). Since this locking process is the same as the locking process in step S37 of FIG. 4, a description thereof is omitted here. At this time, the processing unit 32C stops the time measurement by the timer 32D, and the timer 32D returns the time measurement to the initial value.

  On the other hand, after the automatic locking process is started, if the timer 32D counts the predetermined period of time without receiving a locking request (Yes in step S53), the processing unit 32C executes automatic locking ( Step S54). Thereafter, the processing unit 32C stops the time measurement by the timer 32D, and the timer 32D returns the time measurement to the initial value.

  In short, even if the visitor who unlocked the door 3 finishes the tour and goes out of the facility 2 and forgets to lock the door 3, the processing unit 32 </ b> C will pass a certain period after the door 3 is unlocked. The drive unit 35 is automatically locked with the lock 36. Therefore, even if a visitor different from the resident of the facility 2 uses the facility 2 temporarily, the security of the facility 2 can be improved.

(3) Modifications Modifications are listed below. The modifications described below can be applied in appropriate combination with the above-described embodiments.

  In the embodiment described above, the first password is set assuming a facility visitor as a temporary user different from the resident of the facility. That is, the key information including the first password is distributed to the facility visitors. However, examples of temporary users that are different from the inhabitants of the facility include, for example, security company security guards as well as visitors. Upon receiving notification that a suspicious person has entered the facility 2, the security guard of the security company needs to enter the facility 2 urgently. Therefore, the key information including the first password may be distributed not to the facility visitor but to the security guard of the security company.

  Or in the electric lock system 1, the 3rd password may be set for the guard of a security company separately from the 1st and 2nd password. The third password is updated under an update condition different from the update condition of the second password. The third password is periodically updated in the same manner as the first password.

  In the embodiment described above, the key information included in the unlocking request acquired from the information terminal device 40 is the same as the first password as a condition (specific condition) for starting the automatic locking process. In other words, the electric lock device 30 has started the automatic locking process when an unlock request is received only for a visitor who is given the first password as key information. However, the present invention is not limited to this, and the electric lock device 30 is automatically activated when an unlocking request is received from a resident who is given a second password as a key information or a security company guard who is given a third password. It may be configured to start the locking process. That is, the electric lock device 30 may be configured such that the password that is the target of the automatic locking process can be set and changed as appropriate.

  In this case, for example, the electric lock storage unit 31 may store a flag that can be used to determine whether or not each password is subject to automatic locking processing. The processing unit 32C may determine whether to start the automatic locking process according to the flag. The setting change may be performed, for example, by issuing a change instruction from the server 10 to the electric lock device 30 via the controller 20.

  Further, the electric lock device 30 may be configured such that a “certain period” that is a reference for actually performing automatic locking can be appropriately adjusted for each password. For example, the fixed period corresponding to the first password may be adjusted to 2-3 hours, and the fixed period corresponding to the second password may be adjusted to 5 hours. In other words, the electric lock storage unit 31 may store a certain period corresponding to each password. The adjustment for a certain period may be performed, for example, by issuing a change instruction from the server 10 to the electric lock device 30 via the controller 20.

  Further, the certain period may be in units of minutes or seconds instead of in hours. In other words, the electric lock device 30 may be configured to automatically lock the door 3 immediately (for example, after one minute) after the automatic locking process is started.

  In the above-described embodiment, it is assumed that the first information includes the first password, and the second information includes the second password. However, the first information may include a first identifier in addition to the first password. Similarly, the second information may include a second identifier in addition to the second password. In short, the server 10 may output two passwords and an identifier (ID) as key information in response to a request from the information terminal device 40. And the unlocking process and the locking process in the electric lock device 30 are the key information acquired from the information terminal device 40, the first password and the first identifier in the electric lock storage unit 31, the second password and the second identifier, You may authenticate using. In this case, at least one of the first password and the first identifier may be updated with the first update condition. Similarly, at least one of the second password and the second identifier may be updated with the second update condition.

  In the embodiment described above, the server 10 may notify that the suspicious person is trying to enter the facility 2 when receiving information that the electric lock device 30 has failed to authenticate the key information a plurality of times. . Further, when the server 10 receives information that the key information has been successfully authenticated even though there is no evidence that the key information is output (downloaded) from the server 10 to the information terminal device 40, the suspicious person improperly locks the key. Information may be acquired to notify that the facility 2 has been entered.

  In the above-described embodiment, the information terminal device 40 is a smart phone, a tablet terminal, or the like, but the information terminal device 40 is not limited to these examples. For example, the information terminal device 40 may be an IC card that incorporates a CPU and performs radio communication with the electric lock device 30. In this case, the IC card is inserted into a device that can communicate with the server 10. The device with the IC card attached communicates with the server 10 to receive the first password or the second password, and stores the received first password or second password in the IC card.

(4) Advantages As described above, the electric lock device 30 according to the first aspect includes the drive unit 35, the storage unit (electric lock storage unit 31), and the control unit 32. The drive unit 35 drives the lock 36 of the door 3 of the facility 2 to unlock and lock the door 3. The storage unit (electric lock storage unit 31) stores first information updated under the first update condition and second information updated under a second update condition different from the first update condition. . The control unit 32 controls the drive unit 35 in response to an unlocking request or locking request for the door 3 received from the information terminal device 40. The control unit 32 is configured to receive the unlocking request from the information terminal device 40 and cause the driving unit 35 to automatically lock the door 3 when a specific condition is satisfied. The specific condition includes that the key information received from the information terminal device 40 as the unlocking request matches either one of the first information and the second information.

According to this configuration, if the key information including the first information is distributed to a user (temporary user) who is unfamiliar with unlocking and locking the door 3 and has a low management awareness regarding security, The security of the facility 2 can be further improved. In other words, a temporary user is more likely to forget to lock the door 3 when leaving the facility 2 after using the facility 2, compared to a long-term user (for example, a resident) of the facility. It is possible to reduce the temporary user leaving the door 3 in the unlocked state. In addition, since the first information is regularly updated, the security of the facility 2 is further improved.

  Regarding the electric lock device 30 according to the fourth aspect, in the first aspect or the second aspect, the first update condition is a predetermined period (second predetermined condition) from the time when the information terminal device 40 acquires the key information. It is preferred that the period Ta2) elapses. In this case, it is preferable that the specific condition further includes that the key information received from the information terminal device 40 matches the first information. According to this configuration, if the key information including the first information is distributed to temporary users, the security of the facility 2 can be further improved. That is, similarly to the third aspect, it is possible to reduce the temporary user leaving the door 3 in the unlocked state. The first information is not updated until a predetermined period has elapsed from the time when the information terminal device 40 acquired the key information. Therefore, the first information is updated immediately after the information terminal device 40 acquires the key information. The situation where it cannot be used for unlocking can be reduced.
