In the present embodiment, the communication method between the electric lock control system 1 and the key device 2 is wireless communication using radio waves as a medium. Further, in the present embodiment, both the electric lock control system 1 and the key device 2 are battery-powered. Further, in the present embodiment, the key device 2 is, for example, a mobile terminal having a telephone function. In the present embodiment, the case where the building 4 is a detached house will be described as an example. Therefore, the user 6 of the electric lock control system 1 is the person who owns the key device 2 among the residents of the building 4.

In the present embodiment, the key device 2 transmits the key information stored in advance in the key device 2 to the electric lock control system 1 to enable unlocking and locking of the opening / closing member 5. That is, when the lock-side communication unit 11 and the key device 2 communicate with each other and the lock-side control unit 12 succeeds in authenticating the key information possessed by the key device 2, the electric lock control system 1 unlocks the opening / closing member 5 and unlocks the opening / closing member 5. It is ready to be locked. Here, the electric lock control system 1 may perform authentication by using the operation of the lock side operation unit 13 (described later) by the user 6 as a trigger to lock or unlock the opening / closing member 5. Further, the electric lock control system 1 may lock or unlock the opening / closing member 5 after the successful authentication, waiting for the operation of the lock side operation unit 13 by the user 6. In any case, the electric lock control system 1 has an unlocking operation for switching the opening / closing member 5 from the locked state to the unlocked state and a locking operation for switching the opening / closing member 5 from the unlocked state to the locked state by communicating with the key device 2.

When the control program is executed by the lock side control unit 12, the above-mentioned processing such as authentication is realized. In other words, the control program is the firmware of the electric lock control system 1.

Then, in the present embodiment, the lock-side control unit 12 updates its own control program based on the update information received by the lock-side communication unit 11 from the key device 2. In other words, the lock side control unit 12 updates the control program used before receiving the update information by using the update information. Therefore, after the update, the lock side control unit 12 will execute the latest control program. Here, the update information may be the control program itself or the data of the difference from the control program before the update.

The "control program update" referred to here is an algorithm update mainly used in the control program, such as a change in the authentication algorithm and a bug fix, and does not include an update of the data itself referred to by the control program. Therefore, for example, the registration of the key device 2 with respect to the electric lock control system 1 is not included in the "update of the control program".

As described above, in the present embodiment, the lock side control unit 12 can update its own control program based on the update information received from the key device 2. Therefore, in the present embodiment, it is possible to update the control program related to the control of the electric lock 3 without using a dedicated maintenance device. Therefore, the present embodiment has an advantage that the convenience when updating the control program related to the control of the electric lock 3 can be improved as compared with the case where the dedicated maintenance device is used.

The display unit 25 is a thin display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display content of the display unit 25 is controlled by the key side control unit 21.

(2.3) Electric lock The electric lock 3 unlocks and locks the opening / closing member 5 (here, the entrance door). The electric lock 3 has a dead bolt, a drive unit, and a drive circuit. The drive circuit creates a drive signal according to a control signal (unlocking signal or locking signal) output from the lock side control unit 12, and outputs this drive signal to the drive unit. The drive unit includes an electric motor and a transmission mechanism that transmits the driving force of the electric motor to the dead bolt. The drive unit drives the drive motor according to a drive signal input from the drive circuit. The driving force of the drive motor is transmitted to the dead bolt via the transmission mechanism, so that the dead bolt moves to the locking position or the unlocking position. Here, in the state where the dead bolt is moved to the locked position, at least a part of the dead bolt is inserted into the bolt hole provided in the door frame supporting the opening / closing member 5, and in this state, the opening / closing member 5 is closed. It is held in a state of being. When the dead bolt is moved to the unlocked position, the entire dead bolt is out of the bolt hole, and in this state, the opening / closing member 5 can be opened / closed.

(2.4) Server The server 7 is located away from the building 4 where the electric lock control system 1 is installed, for example, the provider of the electric lock control system 1 or the provider of the service using the electric lock control system 1. It is installed in the facility it owns. The server 7 communicates with the second communication unit 222 of the key device 2 via the network N1. The server 7 mainly includes, for example, a computer system (including a microcomputer) including a processor and a memory. That is, the computer system functions as the server 7 by executing an appropriate program on the processor.

The server 7 stores the update information of the control program related to the control of the electric lock 3 and the update information of the program used by the key device 2. The "program used in the key device 2" here is a program executed by the key side control unit 21, in other words, the firmware of the key device 2. The update information used in the key device 2 may be the program itself or the data of the difference from the program before the update. In the following description, these updated information will also be referred to as "update information group".

The update information group is appropriately updated by, for example, a service provider using the electric lock control system 1. Then, the server 7 transmits the update information group to the key device 2 in response to the request from the key device 2 by communicating with the key device 2. For example, when the user 6 operates the key-side operation unit 23 to perform a specific operation, a request signal requesting an update information group is transmitted from the key-side communication unit 22 to the server 7. When the server 7 receives the request signal, the server 7 transmits the update information group to the key device 2 which is the source of the request signal.

When the key device 2 is a mobile terminal such as a smartphone as in the present embodiment, the update information group is transmitted to the key device 2 in a form included in a dedicated application of the mobile terminal. If the dedicated application is already installed in the key device 2, the update information group is transmitted to the key device 2 as information for updating the dedicated application.

(3) Operation Hereinafter, the operation of the electric lock control system 1 of the present embodiment will be described.

(3.1) Authentication First, authentication by the electric lock control system 1 will be described. The lock-side control unit 12 controls the lock-side communication unit 11 to intermittently drive the antenna to transmit a beacon signal. Here, when the user 6 who owns the key device 2 enters the communication area of the electric lock control system 1, the key side communication unit 22 receives the beacon signal from the lock side communication unit 11. The communication area has a strength required for processing by the key device 2, and is a range in which the key device 2 can receive a wireless signal from the electric lock control system 1.

Upon receiving the beacon signal, the key device 2 transmits a beacon response to the lock-side communication unit 11. When the lock-side communication unit 11 receives the beacon response from the key device 2, the authentication unit 121 executes the authentication process. When the authentication process is successful, the lock side control unit 12 automatically or waits for the operation of the lock side operation unit 13 by the user 6 to control the electric lock 3 to lock or unlock the opening / closing member 5. On the other hand, if the authentication process fails, or if the beacon response from the key device 2 is not received for a certain period of time, the lock side control unit 12 does not control the electric lock 3.

(3.2) Update in the Electric Lock Control System Next, the operation of the lock side control unit 12 of the electric lock control system 1 to update its own control program will be described with reference to FIG. In the following description, the key device 2 updates the program used in the key device 2 in advance by communication with the server 7, and stores the update information of the control program of the electric lock control system 1 in advance. Suppose you have.

When the user 6 who owns the key device 2 enters the communication area of the electric lock control system 1, the electric lock control system 1 starts communication with the key device 2 (step S10). Then, the authentication unit 121 executes the authentication process (step S11). If the authentication process fails (step S12: No), the lock side control unit 12 does not control the electric lock 3 as described above. In this case, even if the key device 2 stores the update information, the lock side communication unit 11 does not receive the update information from the key device 2. On the other hand, when the authentication process is successful (step S12: Yes), the lock side control unit 12 controls the electric lock 3 to lock or unlock the opening / closing member 5 (step S13).

After controlling the electric lock 3 (that is, after the authentication is successful), the lock side communication unit 11 receives the update information stored in the key device 2 by communicating with the key device 2. Then, when the lock side control unit 12 receives the update information from the key device 2 (step S14: Yes), the lock side control unit 12 updates its own control program based on the update information (step S15). On the other hand, when the key device 2 does not store the update information and the lock side communication unit 11 cannot receive the update information from the key device 2 (step S14: No), the lock side control unit 12 has its own control program. Do not update.

(3.3) Update in the key device Next, the operation in which the key side control unit 21 of the key device 2 updates its own program will be described with reference to FIG. In the following description, unlike "(3.2) Update in the electric lock control system", it is assumed that the key device 2 has not yet updated the program used in the key device 2.

First, the key device 2 communicates with the server 7 at the timing when the user 6 operates the key side operation unit 23 or periodically (step S20). At this time, if there is an update information group that the key device 2 has not yet received (step S21: Yes), the key device 2 requests the server 7 to transmit the update information group. Then, the server 7 transmits the update information group to the key device 2 in response to the request from the key device 2. When the key-side communication unit 22 receives the update information group from the server 7, the key-side control unit 21 updates its own program based on the update information of the program used by the key device 2 included in the update information group (step). S22). Further, the key side control unit 21 stores the update information of the control program included in the update information group in the key side storage unit 24. In other words, the key device 2 acquires the update information of the control program included in the update information group (step S23). On the other hand, when there is no update information group that the key device 2 has not yet received (step S21: No), the key side control unit 21 does not update its own program.

After that, when the user 6 who owns the key device 2 enters the communication area of the electric lock control system 1, the key device 2 starts communication with the electric lock control system 1 (step S24). When the authentication process is executed by the electric lock control system 1 and the authentication process fails (step S25: No), the electric lock 3 is not controlled, and the opening / closing member 5 is not locked or unlocked. In this case, even if the key device 2 stores the update information, the key device 2 does not transmit the update information to the electric lock control system 1.

When the authentication process is successful (step S25: Yes) and the key device 2 stores the update information (step S26: Yes), the key device 2 transmits the update information to the electric lock control system 1. do. Even if the authentication process is successful (step S25: Yes), even if the key device 2 does not store the update information (step S26: No), the key device 2 transfers the update information to the electric lock control system 1. Do not send.

As described above, when the key device 2 has acquired the update information in advance, the lock side control unit 12 updates its own control program based on the update information received by the lock side communication unit 11 from the key device 2. do. Therefore, in the present embodiment, it is possible to update the control program related to the control of the electric lock 3 without using a dedicated maintenance device.

Further, in the present embodiment, the lock-side communication unit 11 receives the update information of the control program in a state where the authentication unit 121 has succeeded in authenticating the key device 2. That is, the lock side control unit 12 updates its own control program only when the authentication unit 121 succeeds in authenticating the key device 2. Therefore, the present embodiment has an advantage that it is possible to prevent unauthorized modification of the control program by an unauthorized device without preparing a new authentication means.

(4) Modified Example The above-described embodiment is only one of the various embodiments of the present disclosure. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Hereinafter, modifications of the above-described embodiment will be listed. The modifications described below can be applied in combination as appropriate.

The communication method according to one embodiment is a communication method of the key device 2 having the first communication unit 221 and the second communication unit 222. The first communication unit 221 communicates with the electric lock control system 1. The second communication unit 222 communicates with another system (server 7) different from the electric lock control system 1. This communication method includes an acquisition step and a transmission step. The acquisition step is a step of acquiring update information of a control program related to the control of the electric lock 3 which is the control target of the electric lock control system 1 by communicating with the second communication unit 222 and another system. The transmission step is a step of transmitting at least a part of the acquired update information to the electric lock control system 1 by communication between the first communication unit 221 and the electric lock control system 1.

The program according to one embodiment is a program for causing a computer system to execute the above-mentioned communication method.

Hereinafter, modified examples of the embodiments are listed. The modifications described below can be applied in combination as appropriate.

In the above-described embodiment, the "update of the control program" may include the addition of a function such as adding the remote control function to the key device 2 that does not have the remote control function.

In the above-described embodiment, the lock-side control unit 12 controls the electric lock 3 to lock or unlock the opening / closing member 5, and then confirms the presence / absence of the update information, but the reverse may be performed. That is, in FIG. 3, the lock side control unit 12 may execute steps S14 and S15 before executing step S13.

In the above-described embodiment, the lock-side communication unit 11 receives the update information from the key device 2 when the authentication unit 121 succeeds in authenticating the key device 2, but the purpose is not limited to this. For example, the lock-side communication unit 11 may receive update information from the key device 2 regardless of the success or failure of the authentication of the key device 2 by the authentication unit 121. In other words, the lock side control unit 12 may update its own control program regardless of the success or failure of the authentication of the key device 2 by the authentication unit 121.

In the above-described embodiment, the key device 2 acquires the update information of the control program in advance by updating a dedicated application or the like, but the purpose is not limited to this. For example, the electric lock control system 1 may acquire the update information of the control program from the server 7 by using the key device 2 as a repeater when the authentication is successful. In this case, it is not necessary for the key device 2 to acquire the update information of the control program in advance.

In the above-described embodiment, even if the version of the control program and the version of the program used in the key device 2 are different from each other, at least one of locking and unlocking of the opening / closing member 5 may be possible. For example, when the key device 2 updates the program used in the key device 2 and the electric lock control system 1 does not update the control program, a version difference occurs. Even in such a case, the lock side control unit 12 may execute the authentication process and control the electric lock 3 to lock or unlock the opening / closing member 5. In this aspect, when the control program is updated, the lock side control unit 12 preferably stores the control program before the update in the lock side storage unit 14. Further, in this aspect, when the key side control unit 21 updates the program used in the key device 2, it is preferable that the key side storage unit 24 stores the program before the update.

In the above-described embodiment, the lock-side communication unit 11 may transmit information about its own control program (for example, version information of the control program) to the key device 2. For example, the lock-side communication unit 11 transmits information about its own control program to the key device 2 when a predetermined condition is satisfied. The predetermined condition is, for example, locking or unlocking of the opening / closing member 5. In addition, a predetermined condition is that, for example, the key-side operation unit 23 accepts a specific operation. In this aspect, since the information about the control program is displayed on the display unit 25, there is an advantage that the user 6 can easily grasp whether or not the control program needs to be updated.

In the above-described embodiment, when the update of the control program is completed, the lock-side control unit 12 transmits a notification signal including information indicating that the update of the control program is completed from the lock-side communication unit 11 to the key device 2. You may. Further, the lock-side control unit 12 may transmit a notification signal including information indicating the update status of the control program from the lock-side communication unit 11 to the key device 2 in real time. That is, the lock-side communication unit 11 may transmit information (notification signal) regarding at least one of the update status and the completion of the update of its own control program to the key device 2. In this case, the display unit 25 of the key device 2 displays, for example, a percentage indicating the progress of the update of the control program, the time required to complete the update of the control program, a progress bar, or the like. When notifying the update status of the control program, the lock side control unit 12 calculates information such as a percentage in real time based on, for example, the amount of data downloaded from the key device 2 and the total amount of update information. The calculated information is transmitted from the lock side communication unit 11 to the key device 2. In this aspect, there is an advantage that the user 6 can easily grasp whether or not the update of the control program is completed or how much the update of the control program has progressed.

In the above-described embodiment, the lock-side control unit 12 preferably does not control the electric lock during the update of its own control program. In this case, during the update of the control program, even if the authentication with the key device 2 (including not only the key device 2 used for updating the control program but also other key devices 2) is successful, the opening / closing member 5 is not locked or unlocked. In this aspect, since other processing does not enter during the update of the control program, there is an advantage that the time required for updating the control program can be easily shortened. Further, in this aspect, since the opening / closing member 5 is not locked or unlocked during the update of the control program, there is an advantage that safety can be easily ensured.

In the above-described embodiment, the lock-side communication unit 11 receives the update information of the control program at one time, but the purpose is not limited to this. For example, the lock-side communication unit 11 may receive the update information of the control program in a predetermined number of times in a state where it can communicate with the key device 2. In this aspect, even when the amount of data of the update information of the control program is relatively large, there is an advantage that the time required for receiving the update information of the control program at one time can be shortened. Further, in this embodiment, for example, if the key device 2 receives the update information of the control program each time the key device 2 enters the communication area of the electric lock control system 1, the user 6 repeatedly enters and exits the building 4 on a daily basis. , It is possible to update the control program.

In the above-described embodiment, the update of the control program is preferably performed when the opening / closing member 5 is locked (for example, locked from the inside 41 of the building 4). Further, the control program may be updated when the opening / closing member 5 is in the unlocked state. That is, the lock side control unit 12 may update its own control program during the renewal period when the opening / closing member 5 is in at least one of the locked state and the unlocked state. In this aspect, since the control program is updated for a limited period of time, for example, when the user 6 is staying in the building 4 or when the user 6 enters and exits the building 4, the timing not intended by the user 6 is set. There is an advantage that it is difficult to update the control program.

In the above-described embodiment, the lock-side communication unit 11 receives the update information of the control program regardless of the update intention of the user 6, but the purpose is not limited to this. For example, the lock-side communication unit 11 may receive the update information of the control program when the user 6 who owns the key device 2 receives the signal including the information indicating the intention to update.

In this aspect, the key-side control unit 21 displays, for example, a message on the display unit 25 for confirming the intention of the user 6 to update before the lock-side control unit 12 executes step S15 in FIG. The message is, for example, "Ready to update the control program. Do you want to update?" The user 6 inputs whether or not he / she intends to update the control program by performing an operation of selecting, for example, "Yes" or "No" for this message. When the key-side operation unit 23 receives an input affirming the update of the control program, the key-side control unit 21 sends a signal including information indicating the intention of the update by the user 6 from the key-side communication unit 22 to the electric lock control system 1. Send to.

As a result, the lock side control unit 12 updates its own control program after confirming the intention of the user 6 to update. On the other hand, the lock side control unit 12 does not update its own control program when the user 6 cannot confirm the intention to update. This aspect has an advantage that it is possible to prevent the control program from being updated without the user's knowledge.

As described above, the update of the program used for the lock side control unit 12 may be automatically performed without the intention of the user 6, or may be performed after confirming the intention of the user 6. For example, in the case of updating a control program related to the operation of the user 6, such as changing the user interface or adding a function, it is preferable to confirm the intention of the user. On the other hand, if the control program is updated without being related to the operation of the user 6, such as fixing a bug, the update may be automatically performed without confirming the intention of the user 6.

In the above-described embodiment, the lock-side communication unit 11 may further receive the update information of the program used in the key device 2 in addition to the update information of the control program. Then, the lock-side communication unit 11 transfers the update information of the program used in the key device 2 to another key device 2 different from the key device 2 (that is, the key device 2 other than the key device 2 used to update the control program). You may send it. The timing for transmitting the update information of the program used by the key device 2 is, for example, when the user 6 who owns another key device 2 enters the communication area of the electric lock control system 1. In this aspect, it is possible to update the program used in the key device 2 without acquiring the update information of the program used in the key device 2 by updating the dedicated application in the other key device 2. , Has the advantage. This aspect is particularly useful for the key device 2 which does not have a communication function with the server 7.
