As long as it does not deviate from the technical idea, various changes can be made according to the design and the like.

(Embodiment 1)
The electric lock system 1 of the present embodiment will be described.

As shown in FIG. 1A, the electric lock system 1 includes a server 10, a controller 20, and an electric lock device 30. The controller 20 and the electric lock device 30 are provided in the facility 2. Here, the facility 2 is a building such as a dwelling unit, a detached house, an office, a factory, or a store of an apartment house. The server 10 is provided outside the facility 2, for example, in a security company.

The electric lock device 30 performs an unlocking process for unlocking the lock (lock 36 described later) of the door 3 of the facility 2.

The server 10 issues and manages information used for the unlocking process performed by the electric lock device 30. There are two types of information used in the unlocking process. The first is the first password and the second is the second password. The first password is used by a person who wishes to view a facility that has not yet moved in to enter the facility. The second password is used by the resident (resident) of the facility.

Further, the server 10 can communicate with the information terminal device 40 that requests the electric lock device 30 to unlock the device via a network 4 such as the Internet. Here, the information terminal device 40 is a portable terminal device, for example, a smart phone, a tablet terminal, or the like.

The electric lock device 30 is capable of short-range wireless communication with the information terminal device 40. When the electric lock device 30 receives the request for the unlock process from the information terminal device 40, the electric lock device 30 performs the unlock process and unlocks the lock (lock 36) of the door 3 according to the process 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, the 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 periodic 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 periodic communication). The controller 20 performs the second periodic communication, for example, every hour.

Next, the configuration of the server 10 will be described.

When the server 10 receives the confirmation request information from the controller 20 during the first periodic communication, the server 10 transmits the 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 the program stored in the memory. The program is pre-recorded here in computer memory. The program may be provided by being recorded on a recording medium such as a memory card or through a telecommunication line such as the Internet.

The server storage unit 11 is composed of an electrically rewritable non-volatile semiconductor memory such as a flash memory. The server storage unit 11 stores the first password and the second password.

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

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

The issuing unit 15 issues the first password and the second password when the operation of the electric lock system 1 is started. Specifically, when the issuing unit 15 starts the operation of the electric lock system 1, the first password and the second password are generated and stored in the server storage unit 11. 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.

After that, the issuing unit 15 stores the first password stored in the server storage unit 11 in the server storage unit 11 and the electric lock device 30 during the first periodic communication while the first password is not output to the information terminal device 40. 1 Update the password. For example, the issuing unit 15 generates a new first password at the time of the first periodic 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 it to the electric lock device 30 via the controller 20, and updates the first password stored in the electric lock device 30 in the electric lock device 30. Let me.

The issuing unit 15 clocks the timer 16 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 time of the timer 16 elapses after a predetermined period. When the predetermined period elapses, the timer 16 stops the time counting and sets the timer 16 to the initial value. Here, the 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. After the predetermined period has elapsed, 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 periodic communication. 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 periodic communication is performed within a predetermined period. Therefore, the response information transmitted to the controller 20 within the predetermined period does not include the first password.

When the resident of the facility 2 moves out, the issuing unit 15 receives the eviction information indicating the resident's eviction from the information terminal device 40 via the communication unit 13. Upon receiving the move-out 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 device 30. The issuing unit 15 includes the generated second password in the response information during the first periodic communication and transmits the generated second password to the electric lock device 30 via the communication unit 13 and the controller 20.

By being connected to the network 4, the communication unit 13 enables communication between the server 10 and the information terminal device 40, and between the server 10 and the controller 20.

Next, the configuration of the controller 20 will be described.

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 the program stored in the memory. The program is pre-recorded here in computer memory. The program may be provided by being recorded on a recording medium such as a memory card or through a telecommunication line such as the Internet.

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 of transmitting information to the server 10 via the network 4. The first reception function is a function of 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 by 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 source 5, and is configured to be able to generate an operating power source regardless of whether the battery 25 or the external power source 5 receives power. The power supply unit 23 operates in either a first mode in which an operating power source is generated by the electric power of the battery 25 or a second mode in which an operating power source is generated by the electric power of the external power source 5.

Although not shown in FIG. 2, the power supply unit 23 is electrically connected to the first communication unit 21, the second communication unit 22, and the control unit 24, and is generated by the power supply unit 23. The operating power supply provides electric power for operating 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 according to the power supply state 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 the power is not supplied from the external power source 5 to the power supply unit 23, and sets the operation mode to the second mode when the power is supplied. Switch to mode. As a result, the controller 20 can operate in the first mode when the facility 2 is vacant (vacant house), and in the second mode in other cases.

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 the timing when the first periodic communication is performed and the timing when the first password is used. For example, when the current time reaches the time for performing the first periodic communication, the control unit 24 activates the first communication unit 21 for a predetermined time (for example, 1 minute). Further, in other time zones, the control unit 24 stops the power supply to the first communication unit 21. If the first password is used while the power supply is stopped, the control unit 24 activates the first communication unit 21 for a predetermined time (for example, 1 minute).

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

When the response information received during the first periodic communication includes the second password, the control unit 24 transmits the second update information to the electric lock device 30 via the second radio unit 34. Here, the second update information is information indicating an instruction for updating 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 transmission / reception operation and reception operation at the timing of performing the second periodic communication. For example, when the current time reaches the time for performing the second periodic communication, the control unit 24 activates the second communication unit 22 for a predetermined time (for example, 5 seconds). At other times, the control unit 24 stops the power supply to the second communication unit 22.

When updating the first password stored in the electric lock device 30, the control unit 24 transmits the above-mentioned first update information to the electric lock device 30 at the time of the second periodic communication. When updating the second password stored in the electric lock device 30, the control unit 24 transmits the above-mentioned second update information to the electric lock device 30 at the time of the second periodic communication.

The control unit 24 is operating in the second mode when the operation of the electric lock system 1 is started, and the first communication unit 21 is in an operable state. 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 the first password and the second password. When the first communication unit 21 receives the first password and the second password at the start of the operation of the electric lock system 1, the control unit 24 transmits the received first password and the second password via the second communication unit 22. It is transmitted to the electric lock device 30.

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

Next, the configuration of the electric lock device 30 will be described.

As shown in FIG. 1B, the electric lock device 30 includes an electric lock storage unit 31, a control unit 32, a first radio unit 33, a second radio unit 34, a drive unit 35, and a lock 36. The electric lock device 30 has a CPU (Central Processing Unit) and a memory. The function of the control unit 32 is realized by the CPU executing the program stored in the memory. The program is pre-recorded here in computer memory. The program may be provided by being recorded on a recording medium such as a memory card or through a telecommunication line such as the Internet.

The electric lock storage unit 31 is composed of an electrically rewritable non-volatile 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 37, a reception unit 38, and an unlocking processing unit 39.

When the registration unit 37 receives the first password and the second password from the server 10 via the controller 20 and the first radio unit 33 at the start of the operation of the electric lock system 1, the registration unit 37 receives the received first password and the second password by the electric lock. It is stored in the storage unit 31.

When the registration unit 37 receives the first update information from the server 10 via the controller 20, the registration unit 37 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 37 receives the second update information from the controller 20, the registration unit 37 rewrites (updates) the second password stored in the electric lock storage unit 31 with the second password included in the second update information.

The reception unit 38 receives the unlock request information requesting the unlocking of the lock 36 of the door 3 from the information terminal device 40 via the second radio unit 34. The unlock request information includes key information used for authentication for unlocking the lock 36 of the door 3. When the reception unit 38 receives the unlock request information, the reception unit 38 outputs the key information included in the unlock request information to the unlock processing unit 39.

The unlocking processing unit 39 performs the unlocking processing using the key information and the first password and the second password stored in the electric lock storage unit 31. The unlocking processing unit 39 determines whether or not the key information received from the information terminal device 40 matches any of the first password and the second password. That is, the unlocking processing unit 39 authenticates using the key information and the first password and the second password.

When it is determined that the key information matches either the first password or the second password, that is, it is determined that the authentication is successful, the unlocking processing unit 39 unlocks the lock 36 of the door 3. Specifically, an unlocking instruction indicating an instruction for unlocking the lock 36 is output to the drive unit 35. If it is determined that they do not match, that is, if it is determined that the authentication has failed, the unlocking processing unit 39 does not unlock the lock 36 of the door 3.

When the unlocking process is executed, the unlocking processing unit 39 transmits execution information indicating that the unlocking process has been executed to the server 10 via the first radio unit 33 and the controller 20.

The first radio 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 by using low power wireless communication as a communication method.

The second radio unit 34 is a communication module for communication with the information terminal device 40, and is controlled by the control unit 32. The second radio unit 34 uses low power wireless communication as a communication method to communicate with the information terminal device 40.

Upon receiving the unlocking instruction from the unlocking processing unit 39, the drive unit 35 electrically unlocks the lock 36 provided on the door 3. Here, the lock 36 includes a dead bolt provided on the door 3 and a hole in the door frame into which the dead bolt is fitted. When the drive unit 35 receives the unlocking instruction from the unlocking processing unit 39, the drive unit 35 moves the dead bolt inserted in the hole of the door frame in the direction away from the door frame, and puts out the dead bolt out from the hole of the door frame. This unlocks the lock 36.

Next, the operation of the electric lock system 1 will be described with reference to FIG. Here, the operation of updating the first password for the server storage unit 11 and the electric lock storage unit 31 will be described.

The controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S1).

When the server 10 receives the confirmation request information 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 the 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 new generated 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 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 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 first password stored in the server storage unit 11 is not output to the information terminal device 40, the same operations as in steps S1 to S4 are repeated (steps S5 to S8).

The information terminal device 40 transmits a request for the first password to the server 10 (step S9). When the output unit 14 of the server 10 receives the request for the first password from the information terminal device 40, the output unit 14 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 time counting with the time t1 when the first password is output to the information terminal device 40 as the start time.

The controller 20 transmits confirmation request information at the time when the first periodic communication is performed (step S11). The server 10 transmits the response information to the controller 20 (step S12). At this time, the issuing unit 15 does not generate the first password because the time of the timer 16 has not passed the predetermined period Ta. That is, the server 10 transmits the 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 also not updated. Here, the predetermined period Ta is a period from time t1 to time t2.

The information terminal device 40 transmits the unlock request information to the electric lock device 30 (step S13). At this time, the information terminal device 40 includes the first password received in step S10 as key information in the unlock request information, and transmits the unlock request information to the electric lock device 30.

Upon receiving the unlock request information, the unlock processing unit 39 of the electric lock device 30 performs the unlock process (step S14). Specifically, the unlocking processing unit 39 determines whether or not the key information included in the unlocking request information matches any of the first password and the second password. If they match, the unlocking processing unit 39 causes the driving unit 35 to unlock the lock 36. When the unlocking process is executed, the unlocking processing unit 39 transmits execution information to the server 10 via the controller 20 (step S15).

After that, the controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S16). The server 10 transmits the response information to the controller 20 (step S17). At this time, the issuing unit 15 does not generate the first password because the time of the timer 16 has not passed the predetermined period Ta.

The controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S18).

Here, the confirmation request information is received only after the predetermined period Ta has elapsed. The issuing unit 15 generates a new first password, and transmits the 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 new generated 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). The timer 16 stops the time counting when the predetermined period Ta elapses, and sets the timer 16 to the initial value.

When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 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 of the present embodiment, the first password stored in both the server storage unit 11 and the electric lock storage unit 31 while the first password is not output to the information terminal device 40. Is updated regularly. For example, it is updated once a day. That is, the first password stored in the server storage unit 11 and the electric lock storage unit 31 on the condition that a predetermined period has elapsed from the time when the update is performed for the predetermined cycle, specifically, the first password. Is updated. As a result, the password is updated even while the first password is not output, so that the security is enhanced.

Further, in the electric lock system 1 of the present embodiment, after the first password is output to the information terminal device 40, the first password is stored in the server storage unit 11 and the electric lock storage unit 31 until a predetermined period Ta elapses. 1 Password is not updated. In other words, the first password stored in the server storage unit 11 and the electric lock storage unit 31 is subject to the update condition that a predetermined period has elapsed since the output unit 14 outputs the first password to the information terminal device 40. The update will be done. As a result, it is possible to prevent the first password stored in the server storage unit 11 and the electric lock storage unit 31 from being updated without using the output first password. For example, it is assumed that the time when the first password is output to the information terminal device 40 is 5 minutes before the time when it is periodically updated. In this case, it may be difficult for the user of the information terminal device 40 to arrive at the facility 2 in 5 minutes. Therefore, when the user of the information terminal device 40 arrives at the facility 2, the first password stored in the server storage unit 11 and the electric lock storage unit 31 is updated, and is stored in the information terminal device 40. There is a possibility that the lock 36 of the door 3 cannot be unlocked with one password. That is, the user of the information terminal device 40 may not be able to view the facility 2. Therefore, the user of the information terminal device 40 can view the facility 2 by setting the update condition of the first password as the elapse of a predetermined period after the output unit 14 outputs the first password to the information terminal device 40. It is possible to reduce the possibility that it cannot be done. In other words, it is possible to reduce the possibility that the first password stored in the server storage unit 11 and the electric lock storage unit 31 will be updated without using the output first password.

Further, in the electric lock system 1 of the present embodiment, the second password is updated triggered by the resident of the facility 2 moving out. That is, in the electric lock system 1 of the present embodiment, it is a condition for updating the second password stored in the server storage unit 11 and the electric lock storage unit 31 that the resident of the facility 2 moves out. On the other hand, the update condition of the first password is a predetermined cycle (for example, once a day) while the first password is not output to the information terminal device 40. Further, the condition for updating the first password after the first password is output to the information terminal device 40 is that a predetermined period has elapsed since the first password was output to the information terminal device 40. In short, it can be said that the first password is updated more frequently than the second password.

(Embodiment 2)
In the first embodiment, the confirmation request information is transmitted from the controller 20, but in the present embodiment, the confirmation request information is transmitted from the server 10 to the controller 20, which is different from the first embodiment. Hereinafter, the electric lock system 1 of the present embodiment will be described with a focus on points different from those of the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

In the present embodiment, the control unit 12 of the server 10 first receives confirmation request information including a new first password generated by the issuing unit 15 while the first password is not output to the information terminal device 40. It is output to the controller 20 at the timing of regular communication. When the new second password is generated, the control unit 12 includes the new second password in the confirmation request information during the first periodic communication and transmits the new password to the controller 20.

In the present embodiment, when the control unit 24 of the controller 20 receives the confirmation request information from the server 10 during the first periodic communication, the control unit 24 transmits the response information to the server 10. When the confirmation request information received during the first periodic communication includes the first password, the control unit 24 transmits the first update information including the first password to the electric lock device 30. When the confirmation request information received during the first periodic communication includes the second password, the control unit 24 transmits the second update information including the second password to the electric lock device 30.

Hereinafter, the operation of the electric lock system 1 of the present embodiment will be described with reference to FIG. Here, the operation of updating the first password stored in the server storage unit 11 and the electric lock storage unit 31 will be described.

When the time for performing the first periodic communication comes, the issuing unit 15 of the server 10 generates a new first password if the first password is not output to the information terminal device 40. The issuing unit 15 transmits the confirmation request information including the generated new first password to the controller 20 (step S50). At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the new generated first password.

The controller 20 includes the first password included in the confirmation request information in the first update information and transmits the first password to the electric lock device 30 (step S51). When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S52). The controller 20 transmits the response information to the server 10 (step S53).

While the first password stored in the server storage unit 11 is not output to the information terminal device 40, the same operations as in steps S50 to S53 are repeated (steps S54 to S57).

The information terminal device 40 transmits a request for the first password to the server 10 (step S58). When the output unit 14 of the server 10 receives the request for the first password from the information terminal device 40, the output unit 14 outputs the first password stored in the server storage unit 11 to the information terminal device 40 (step S59). At this time, the timer 16 starts time counting with the time t11 when the first password is output to the information terminal device 40 as the start time.

The server 10 transmits the confirmation request information to the controller 20 at the time when the first periodic communication is performed (step S60). The controller 20 transmits the response information to the server 10 (step S61). At this time, the issuing unit 15 of the server 10 does not generate the first password because the time of the timer 16 has not passed the predetermined period Tb. That is, the server 10 transmits the confirmation request 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 issuing unit 15 does not update the first password stored in the server storage unit 11. Here, the predetermined period Tb is a period from time t11 to time t12.

The information terminal device 40 transmits unlock request information to the electric lock device 30 (step S62). At this time, the information terminal device 40 includes the first password received in step S59 as the key information in the unlock request information, and transmits the unlock request information.

Upon receiving the unlock request information, the unlock processing unit 39 of the electric lock device 30 performs the unlock process (step S63). When the unlocking process is executed, the unlocking processing unit 39 transmits execution information to the server 10 via the controller 20 (step S64).

After that, the server 10 transmits the confirmation request information at the time when the first periodic communication is performed (step S65). The controller 20 transmits the response information to the controller 20 (step S66). At this time, the issuing unit 15 does not generate the first password because the time of the timer 16 has not passed the predetermined period Tb.

The server 10 transmits the confirmation request information to the controller 20 at the time when the first periodic communication is performed (step S67). The controller 20 transmits the response information to the server 10 (step S68). At this time, the issuing unit 15 of the server 10 does not generate the first password because the time of the timer 16 has not passed the predetermined period Tb. That is, the server 10 transmits the confirmation request information that does not include the first password to the controller 20.

The server 10 transmits the confirmation request information to the controller 20 at the time when the first periodic communication is performed (step S69). Here, since the confirmation request information is received only after the predetermined period Tb has elapsed, the issuing unit 15 generates a new first password and transmits the generated new first password to the controller 20. At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the new generated first password. The timer 16 stops the time counting when the predetermined period Tb elapses, and sets the timer 16 to the initial value.

The controller 20 includes the first password included in the confirmation request information in the first update information and transmits the first password to the electric lock device 30 (step S70). When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S71). The controller 20 transmits the response information to the server 10 (step S72).

As described above, in the electric lock system 1 of the present embodiment, as in the first embodiment, the server storage unit 11 and the electric lock storage unit 31 store the first password while the first password is not output to the information terminal device 40. The first password is updated regularly. Therefore, the first password is updated even while the first password is not output from the server 10 to the information terminal device 40, so that the security is enhanced.

Further, in the electric lock system 1 of the present embodiment, as in the first embodiment, after the first password is output from the server 10 to the information terminal device 40, the first password is updated until a predetermined period Tb elapses. Not done. As a result, it is possible to reduce the possibility that the first password will be updated without using the output first password.

In FIG. 4, the processing order is such that the controller 20 transmits the response information after the electric lock device 30 updates the first password, but the order is not limited to this. The update of the first password by the electric lock device 30 may be performed after the controller 20 transmits the response information.

(Embodiment 3)
In the second embodiment, the first password is not updated until a predetermined period has elapsed after the first password is output from the server 10 to the information terminal device 40. In the electric lock system 1 of the present embodiment, the first password is updated after the first password is output to the information terminal device 40 when the first periodic communication exceeds a predetermined number of times. It's a different point. Hereinafter, the electric lock system 1 of the present embodiment will be described focusing on the differences from the second embodiment. The same components as those in the second embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

When the first password stored in the server storage unit 11 is output to the information terminal device 40, the control unit 12 of the server 10 of the present embodiment counts the number of subsequent first periodic communications. When the count exceeds a predetermined number of times, the control unit 12 generates a new first password at the next first periodic communication, includes the new first password in the confirmation request information, and transmits the new first password to the controller 20.

Hereinafter, the operation of the electric lock system 1 of the present embodiment will be described with reference to FIG. Here, the operation of updating the first password will be described.

At the time when the first periodic communication is performed, the issuing unit 15 of the server 10 generates a new first password when the first password stored in the server storage unit 11 is not output to the information terminal device 40. do. The server 10 transmits the confirmation request information including the generated new first password to the controller 20 (step S100).

The controller 20 includes the first password included in the confirmation request information in the first update information and transmits the first password to the electric lock device 30 (step S101). When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S102). The controller 20 transmits the response information to the server 10 (step S103).

While the first password is not output to the information terminal device 40, the same operations as in steps S100 to S103 are repeated (steps S104 to S107).

The information terminal device 40 transmits a request for the first password to the server 10 (step S108). When the output unit 14 of the server 10 receives the request for the first password from the information terminal device 40, the output unit 14 outputs the first password stored in the server storage unit 11 to the information terminal device 40 (step S109). At this time, the control unit 12 counts the number of subsequent first periodic communications.

The server 10 transmits the confirmation request information to the controller 20 at the time when the first periodic communication is performed (step S110). The controller 20 transmits the response information to the server 10 (step S111). At this time, the issuing unit 15 of the server 10 does not generate the first password because the number of times of the first periodic communication does not exceed the predetermined number of times (for example, twice). That is, the server 10 transmits the confirmation request 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 issuing unit 15 does not update the first password stored in the server storage unit 11.

The information terminal device 40 transmits unlock request information to the electric lock device 30 (step S112). At this time, the information terminal device 40 includes the first password received in step S109 as key information in the unlock request information, and transmits the unlock request information.

Upon receiving the unlock request information, the unlock processing unit 39 of the electric lock device 30 performs the unlock process (step S113). When the unlocking process is executed, the unlocking processing unit 39 transmits execution information to the server 10 via the controller 20 (step S114).

After that, the server 10 transmits the confirmation request information at the time when the first periodic communication is performed (step S115). The controller 20 transmits the response information to the controller 20 (step S116). At this time, the issuing unit 15 does not generate the first password because the number of times of the first periodic communication does not exceed the predetermined number of times.

The server 10 transmits the confirmation request information to the controller 20 at the time when the first periodic communication is performed (step S117). At this time, since the number of times of the first periodic communication (in this case, the third time) exceeds the predetermined number of times (twice), the issuing unit 15 of the server 10 generates a new first password and generates it. The new first password is transmitted to the controller 20.

The controller 20 includes the first password included in the confirmation request information in the first update information and transmits the first password to the electric lock device 30 (step S118). When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S119). The controller 20 transmits the response information to the server 10 (step S120).

As described above, in the electric lock system 1 of the present embodiment, as in the second embodiment, the first password is periodically updated while the first password is not output from the server 10 to the information terminal device 40. .. Therefore, the password is updated even while the first password is not output, so that the security is strengthened.

Further, in the electric lock system 1 of the present embodiment, the first password is not updated until the first periodic communication exceeds a predetermined number of times. As a result, it is possible to reduce the possibility that the first password will be updated without using the output first password.

In FIG. 5, the processing order is such that the controller 20 transmits the response information after the electric lock device 30 updates the first password, but the order is not limited to this. The update of the first password by the electric lock device 30 may be performed after the controller 20 transmits the response information.

Further, the electric lock system 1 of the present embodiment may be applied to the first embodiment. That is, as a condition for updating the first password stored in the server storage unit 11 and the electric lock device 30, a predetermined number of times may be used instead of the predetermined period Ta.

(Embodiment 4)
In the first embodiment, the timing at which the timer 16 of the server 10 clocks the time is different from that of the first embodiment. Hereinafter, the electric lock system 1 of the present embodiment will be described with a focus on points different from those of the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The timer 16 starts time counting when the unlocking process is performed by the electric lock device 30. Specifically, the timer 16 starts time counting from the time when the server 10 receives the execution information from the electric lock device 30 via the controller 20.

The issuing unit 15 of the server 10 is a period (first period) from when the output unit 14 outputs the first password to the information terminal device 40 until the server 10 receives the execution information from the electric lock device 30 via the controller 20. No new first password is generated in Tc). Further, the issuing unit 15 does not generate a new first password within the period (second period Td) from when the server 10 receives the execution information from the electric lock device 30 via the controller 20 until a predetermined time elapses. .. That is, the issuing unit 15 does not generate a new first password within the total period of the first period Tc and the second period Td. When the issuing unit 15 receives the confirmation request information from the controller 20 for the first time after the above-mentioned total period has elapsed, the issuing unit 15 generates a new first password.

Next, the operation of the electric lock system 1 will be described with reference to FIG. Here, the operation of updating the first password will be described.

The controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S150).

When the server 10 receives the confirmation request information from the controller 20, the issuing unit 15 of the server 10 receives a new first password when the first password stored in the server storage unit 11 is not output to the information terminal device 40. Generate a password. The issuing unit 15 transmits the response information including the generated new first password to the controller 20 (step S151). At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the new generated first 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 S152). When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S153).

While the first password stored in the server storage unit 11 is not output to the information terminal device 40, the same operations as in steps S150 to S153 are repeated (steps S154 to S157).

The information terminal device 40 transmits the request for the first password to the server 10 (step S158). When the output unit 14 of the server 10 receives the request for the first password from the information terminal device 40, the output unit 14 outputs the first password stored in the server storage unit 11 to the information terminal device 40 (step S159).

The controller 20 transmits confirmation request information at the time when the first periodic communication is performed (step S160). The server 10 transmits the response information to the controller 20 (step S161). At this time, since the issuing unit 15 has not received the execution information from the electric lock device 30 via the controller 20, the issuing unit 15 does not generate the first password. That is, the server 10 transmits the 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. Further, the issuing unit 15 does not update the first password stored in the server storage unit 11.

The information terminal device 40 transmits the unlock request information to the electric lock device 30 (step S162). At this time, the information terminal device 40 includes the first password received in step S159 as key information in the unlock request information, and transmits the unlock request information to the electric lock device 30.

Upon receiving the unlock request information, the unlock processing unit 39 of the electric lock device 30 performs the unlock process (step S163). When the unlocking process is executed, the unlocking processing unit 39 transmits execution information to the server 10 via the controller 20 (step S164). At this time, when the execution information is received by the server 10, the timer 16 starts time counting with the time t21 at which the execution information is received as the start time.

After that, the controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S165). The server 10 transmits the response information to the controller 20 (step S166). At this time, the issuing unit 15 does not generate the first password because the time of the timer 16 has not passed the second period Td. Here, the second period Td is a period from time t21 to time t22.

The controller 20 transmits the confirmation request information to the server 10 at the time when the first periodic communication is performed (step S167).

Here, since the confirmation request information is received only after the second period Td has elapsed, the issuing unit 15 generates a new first password and sends the response information including the generated new first password to the controller 20. Transmit (step S168). At this time, the issuing unit 15 updates the first password stored in the server storage unit 11 with the new generated first 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 S169). The timer 16 stops the time counting when the second period Td elapses, and sets the timer 16 to the initial value.

When the registration unit 37 of the electric lock device 30 receives the first update information from the controller 20, the registration unit 37 updates the first password stored in the electric lock storage unit 31 to the first password included in the first update information ( Step S170).

In the present embodiment, the server 10 has a timer 16 but is not limited to this configuration. The controller 20 may have a timer. In this case, the timer of the controller 20 starts timing the time when the execution information is transmitted to the server 10. The control unit 24 of the controller 20 includes a request for updating the first password in the confirmation request information and transmits the request for updating the first password to the server 10 at the first first periodic communication after the timer has elapsed the second period Td. After the output unit 14 outputs the first password to the information terminal device 40, the issuing unit 15 of the server 10 does not update the first password until the confirmation request information including the request for updating the first password is received. When the issuing unit 15 receives the confirmation request information including the request for updating the first password, the issuing unit 15 generates a new first password.

The request for updating the first password may be made when the second period Td has elapsed. In this case, when the second period Td elapses, the controller 20 transmits the update request information requesting the update of the first password to the server 10. Upon receiving the update request information, the issuing unit 15 generates a new first password. The issuing unit 15 updates the first password stored in the server storage unit with a new first password, and outputs the new first password to the controller 20. The controller 20 outputs a new first password to the electric lock device 30 at the time of the second periodic communication.

Alternatively, when the server 10 receives the execution information from the electric lock device 30 via the controller 20, it generates a new first password and temporarily stores it in a storage area different from the server storage unit 11. , May be transmitted to the controller 20. In this case, the controller 20 temporarily holds the new first password until the second period Td elapses. When the second period Td elapses, the controller 20 outputs the first update information including the new first password temporarily held to the electric lock device 30. Further, the controller 20 transmits an instruction (update instruction) for updating the first password to the server 10. When the server 10 receives the update instruction from the controller 20, the server 10 updates the first password stored in the server storage unit 11 with a new first password temporarily stored.

As described above, in the electric lock system 1 of the present embodiment, the first password stored in the server 10 and the electric lock device 30 is not updated in the first period Tc. The first period Tc is a period from the time t20 when the first password is output from the information terminal device 40 from the server 10 to the time t21 when the server 10 receives the execution information from the electric lock device 30 via the controller 20. .. Further, even in the second period Td, the first password stored in the server 10 and the electric lock device 30 is not updated. That is, during the total period of the first period Tc and the second period Td, the first password stored in the server 10 and the electric lock device 30 is not updated. In other words, the first password stored in the server 10 and the electric lock device 30 is updated on the condition that the total period of the first period Tc and the second period Td elapses.

In the electric lock system 1 of the first embodiment, after the first password is output from the server 10 to the information terminal device 40, the first password is always updated when a predetermined period Ta elapses. Since the predetermined period Ta is a fixed period, it is necessary to use the first password within the predetermined period Ta.

On the other hand, in the electric lock system 1 of the present embodiment, the first period Tc starts at the time when the first password is output from the server 10 to the information terminal device 40, and ends the time when the server 10 receives the execution information. It is a time point. Therefore, the predetermined period Tc is a fluid period. Since the second period Td is a period starting from the time when the server 10 receives the execution information, so to speak, when the first password is used, the first password can be used at least once. Further, since the first password is not updated at least within the period Td after the first password is used, it is highly convenient to compare the one-time password that can be used only once. For example, even if a user who previews the facility 2 goes out of the facility 2 to see the appearance after seeing the inside of the facility 2 once, he / she can re-enter the facility 2. On the other hand, when a one-time password is used, once the person goes out of the facility 2, he / she cannot enter the facility 2 again.

Further, in the present embodiment, when the first period Tc has passed a specific period (for example, 3 days), the server 10 stores the first period Tc in the server storage unit 11 and the electric lock storage unit 31. You may force the password to be updated.

Further, the electric lock system 1 of the present embodiment may be applied to the second embodiment. That is, as the update condition of the first password stored in the server storage unit 11 and the electric lock device 30, the total period of the first period Tc and the second period Td may be used instead of the predetermined period Ta.

(Embodiment 5)
The present embodiment is different from the first embodiment in that the server 10 notifies according to the output status of the first password. Hereinafter, the electric lock device 30 of the present embodiment will be described with a focus on the differences from the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

In the present embodiment, the control unit 12 of the server 10 further includes a determination unit 17 and a notification unit 18, as shown in FIG.

The server storage unit 11 of the present embodiment stores the first flag indicating whether or not the first password stored in the server storage unit 11 is output to the information terminal device 40 in association with the first password. There is. The server storage unit 11 stores a second flag indicating whether or not the second password stored in the server storage unit 11 is output to the information terminal device 40 in association with the second password.

The determination unit 17 determines whether or not the first password stored in the server storage unit 11 has already been output. The notification unit 18 performs notification by voice, a message, or the like according to the determination result of the determination unit 17.

Hereinafter, the operation of the server 10 included in the electric lock system 1 of the present embodiment will be described with reference to the flow chart of FIG.

When the communication unit 13 receives the execution information from the electric lock device 30 via the controller 20 (step S200), the determination unit 17 stores the first password in the server storage unit 11 based on the content represented by the first flag. Determines whether or not has been output (step S201). When the determination unit 17 determines that the first password stored in the server storage unit 11 has been output (“Yes” in step S201), the process ends. When the determination unit 17 determines that the first password stored in the server storage unit 11 has not been output (“No” in step S201), the notification unit 18 notifies (step S202). For example, when the server 10 has a speaker, it outputs voice. Further, when the server 10 has a display unit such as a display, it displays a message.

Here, the authentication result of the unlocking process may be included in the execution information. In this case, in addition to the above processing, the server 10 performs notification according to the authentication result. Hereinafter, the notification process according to the authentication result will be described with reference to the flow chart shown in FIG.

When the communication unit 13 receives the execution information including the authentication result from the electric lock device 30 via the controller 20 (step S250), the determination unit 17 determines whether or not the authentication is successful based on the authentication result (step S250). Step S251). When the determination unit 17 determines that the authentication is successful (“Yes” in step S251), the process ends. When the determination unit 17 determines that the authentication has not succeeded, that is, the authentication has failed (“No” in step S251), the notification unit 18 notifies (step S252).

The two processes described above may be integrated into one process. In this case, for example, when the determination unit 17 determines that the first password has been output (“Yes” in step S201), the determination unit 17 executes step S251. If the authentication is successful, the process ends. If the first password is not output, or if the authentication has failed, the notification unit 18 notifies.

Further, the server 10 may perform the above-mentioned two processes (processes shown in FIGS. 8 and 9), or may perform either one of them.

Further, in the present embodiment, the server 10 is configured to output voice and display a message as notification, but the present invention is not limited to this configuration. The notification unit 18 may output voice information, a message, or the like to the controller 20 to notify the controller 20. Alternatively, the server 10 may output voice information, a message, or the like to the electric lock device 30 via the controller 20 to notify the electric lock device 30. Alternatively, the notification unit 18 may output voice information, a message, or the like to an external device of the electric lock system 1, for example, a management center of a security company.

Further, the above two processes may be applied when the second password is used for the unlocking process. In this case, each time the second password is used for the unlocking process, one of the above two processes may be performed, and only when the second password is used for the unlocking process for the first time, the above two processes may be performed. Alternatively, either one may be performed.

Moreover, this embodiment may be applied to Embodiments 2-4. That is, the server 10 described in the second to fourth embodiments may store the first flag and the second flag and perform the processes shown in FIGS. 8 and 9.

(Modification example)
