FIG. 1 is a block diagram showing a configuration of an electric lock system according to an embodiment of the present invention. 2A and 2B are explanatory diagrams for explaining the operation of the electric lock system. FIG. 3 is a flowchart for explaining the operation of the electric lock system.

(1) Outline of Electric Lock System An electric lock system 10 according to the present embodiment includes a key device 1 and an electric lock device 2 as shown in FIGS. 2A and 2B.

  The electric lock device 2 is a device that locks the entrance 4 of the building 3. The “entrance / exit” of the building 3 here is a door or window that separates the inside of the building 3 (inside 31) from the outside (outside of the house 32), and is, for example, an entrance door, a doorway, or a sweep window. . The electric lock device 2 is installed at the entrance 4. Here, the electric lock device 2 is configured to be able to communicate with the key device 1, and switches between a locked state in which the doorway 4 is locked and an unlocked state in which the doorway 4 is unlocked by communication with the key device 1. Do it electrically.

  The key device 1 has a communication function with the electric lock device 2. In the present embodiment, the communication method between the key device 1 and the electric lock device 2 is wireless communication using radio waves as a medium. The key device 1 is battery-driven and has an appropriate size so that it can be carried by the user 5. In the present embodiment, the key device 1 is configured in a tag shape that can be attached to a bag or the like possessed by the user 5 (see FIG. 2A).

  This embodiment demonstrates as an example the case where the building 3 is a detached house. The user 5 is a person who owns (carries) the key device 1 among the residents of the building 3 (detached house).

  As a basic function of the electric lock system 10, the key device 1 transmits a key ID (Identification) stored in advance in the key device 1 to the electric lock device 2. Allows unlocking. That is, when the key device 1 and the electric lock device 2 communicate with each other and the key ID of the key device 1 is successfully authenticated, the electric lock device 2 is in a state in which the doorway 4 can be unlocked. Then, after the authentication is successful, the electric lock device 2 waits for a predetermined operation (unlocking operation) of the first operation unit 25 or the second operation unit 26 (both see FIG. 1) and unlocks the entrance 4. As a result, the electric lock device 2 performs an unlocking operation for switching from the locked state to the unlocked state by communication with the key device 1. Here, in the present embodiment, the above-described key ID is authentication information of the key device 1.

  The unlocking operation by the electric lock device 2 as described above is performed at least when the user 5 is outside the home 32, that is, when the user 5 is home, and when the user 5 is in the home 31, that is, when the user 5 is out. Done on one side. In the present embodiment, the unlocking operation by the electric lock device 2 is performed both when the user 5 goes home and when he goes out. That is, when the user 5 returns home, the user 5 who is outside the home 32 is in the state of being close to the entrance / exit 4 to the extent that radio waves for communication between the key device 1 and the electric lock device 2 can reach, for example. The key device 1 to communicate with the electric lock device 2 enables the doorway 4 to be unlocked. Similarly, when the user 5 goes out, the user 5 who is in the house 31 has the user 5 in the state where the user 5 is close to the entrance / exit 4 so that the radio wave for communication between the key device 1 and the electric lock device 2 can reach, for example. The key device 1 to communicate with the electric lock device 2 enables the doorway 4 to be unlocked. However, when the user 5 goes out, it is not always necessary for the key device 1 and the electric lock device 2 to communicate to authenticate the key ID of the key device 1, and only the unlocking operation by the second operation unit 26 is performed. May be unlocked.

  Although detailed description is omitted in the present embodiment, the electric lock device 2 succeeds in the authentication of the key ID by communication with the key device 1 in a state where the doorway 4 is unlocked, and the first operation unit 25. Alternatively, when a predetermined operation (locking operation) is performed at the second operation unit 26, the doorway 4 is locked. That is, the electric lock device 2 can perform not only the unlocking operation but also a locking operation for switching from the unlocked state to the locked state by communication with the key device 1.

(2) Configuration of Key Device Next, the configuration of the key device 1 according to the present embodiment will be described with reference to FIG.

  The key device 1 includes a key side communication unit 11, a control unit 12, and a storage unit 13.

  The memory | storage part 13 consists of non-volatile memories, for example. The storage unit 13 stores a key ID unique to the key device 1.

  The key-side communication unit 11 is configured to be able to communicate with the electric lock device 2. A communication method between the key side communication unit 11 and the electric lock device 2 (lock side communication unit 21) is, for example, wireless communication using radio waves such as Bluetooth (registered trademark) as a medium. In the present embodiment, the key device 1 not only transmits a signal to the electric lock device 2 but also receives signals such as a connection request signal and an ID request signal from the electric lock device 2 (lock side communication unit 21). . Therefore, the key side communication unit 11 has a signal transmission function and a reception function, and performs bidirectional communication with the lock side communication unit 21.

  In this embodiment, the control unit 12 is constituted by a microcomputer having a CPU (Central Processing Unit) and a memory as main components. In other words, the control unit 12 is realized by a computer having a CPU and a memory, and the computer functions as the control unit 12 when the CPU executes a program stored in the memory. Here, the program executed by the CPU is recorded in advance in the memory of the microcomputer, but may be provided by being recorded through a telecommunication line such as the Internet or a recording medium such as a memory card.

  The control unit 12 controls the key side communication unit 11. The control unit 12 enables unlocking of the doorway 4 in the electric lock device 2 by causing the key side communication unit 11 to receive at least a signal from the electric lock device 2 (lock side communication unit 21). Specifically, the control unit 12 transmits a signal (connection request signal) transmitted from the lock side communication unit 21 for starting communication between the key side communication unit 11 and the lock side communication unit 21 to the key side communication unit. 11 to receive. In response to this, the control unit 12 causes the key side communication unit 11 to transmit a response signal (ACK: ACKnowledgement) to the connection request signal from the lock side communication unit 21. When the communication between the key side communication unit 11 and the lock side communication unit 21 is established, the control unit 12 reads the key ID from the storage unit 13, and the key side communication unit 11 sends the key ID to the lock side communication unit 21. Including the signal (ID signal).

(3) Configuration of Electric Lock Device Next, the configuration of the electric lock device 2 will be described with reference to FIG.

  The electric lock device 2 includes a lock side communication unit 21, a signal processing unit 22, an authentication unit 23, a lock drive unit 24, a first operation unit 25, and a second operation unit 26. The signal processing unit 22 includes a determination unit 221, a mode selection unit 222, and a storage unit 223. The electric lock device 2 is built in, for example, a door (for example, an entrance door) serving as an entrance / exit 4 (see FIG. 2A). The electric lock device 2 may operate by receiving power supply from an external power source such as a system power source (commercial power source) or may be battery-driven.

  The lock side communication unit 21 is configured to be able to communicate with the key device 1 (key side communication unit 11). As described above, since the lock side communication unit 21 and the key device (key side communication unit 11) communicate bidirectionally, the lock side communication unit 21 has a signal transmission function and a reception function.

  In the authentication unit 23, at least one registration ID is registered (stored). The registration ID corresponds to the key ID of the key device 1. For example, when each resident of the building 3 has an individual key device 1, that is, when the electric lock system 10 includes a plurality of key devices 1, the authentication unit 23 includes the plurality of key devices. A plurality of registration IDs corresponding to one key ID are registered. The lock drive unit 24 switches between a locked state and an unlocked state by driving the lock of the doorway 4.

  In this embodiment, the signal processing unit 22 is configured by a microcomputer having a CPU and a memory as main components. In other words, the signal processing unit 22 is realized by a computer having a CPU and a memory, and the computer functions as the signal processing unit 22 when the CPU executes a program stored in the memory. Here, the program executed by the CPU is recorded in advance in the memory of the microcomputer, but may be provided by being recorded through a telecommunication line such as the Internet or a recording medium such as a memory card.

  The signal processing unit 22 controls the lock side communication unit 21, the authentication unit 23, and the lock drive unit 24. The signal processing unit 22 causes the key device 1 (key side communication unit 11) to periodically transmit a signal (connection request signal) from the lock side communication unit 21. When the lock side communication unit 21 receives a response signal (ACK) from the key device 1 as a response to the connection request signal, the signal processing unit 22 determines that communication has been established, and from the lock side communication unit 21 The key communication unit 11 is caused to transmit a signal requesting a key ID (ID request signal). When the lock side communication unit 21 receives a signal (ID signal) including the key ID as a response to the ID request signal, the signal processing unit 22 is registered in advance in the key ID and authentication unit 23 included in the ID signal. By causing the authentication unit 23 to collate with the registered ID, the key ID authentication process is executed. When the key ID is successfully authenticated, in this embodiment, the signal processing unit 22 controls the lock driving unit 24 using a predetermined operation (unlocking operation) on the first operation unit 25 or the second operation unit 26 as a trigger. And unlock the entrance 4.

  The first operation unit 25 and the second operation unit 26 have a function of accepting an operation by the user 5. The 1st operation part 25 consists of pushbutton switches provided in the exterior 32 side of the entrance / exit 4, for example. The 2nd operation part 26 consists of pushbutton switches provided in the in-home 31 side of the entrance / exit 4, for example. The first operation unit 25 and the second operation unit 26 may be, for example, a door handle (handle) provided on the door of the entrance 4 or a touch sensor that detects an operation of the user 5 touching the door handle. There may be. In addition, since the 2nd operation part 26 is provided in the in-home 31 side of the entrance / exit 4, the 2nd operation part 26 is normally operated by the resident of the building 3. FIG. Therefore, when unlocking the entrance / exit 4 from the home 31, the key ID authentication process of the key device 1 may not be performed. However, when unlocking the entrance / exit 4 from the home 31, it is optional whether or not to perform the key ID authentication process of the key device 1.

  The determination unit 221 is provided in the signal processing unit 22, and the computer functions as the determination unit 221 when the CPU executes a program stored in the memory. The determination unit 221 determines whether the key device 1 is in the building 3 (inside the house 31) or outside (outside the house 32). At this time, the determination unit 221 performs the key device depending on whether or not a predetermined condition (first condition) is satisfied after unlocking the entrance 4 by performing a predetermined operation (unlocking operation) on the first operation unit 25. Whether 1 is in the house 31 or outside the house 32 is determined. Further, the determination unit 221 determines whether the key device 1 satisfies the prescribed condition (second condition) after unlocking the entrance 4 by performing a predetermined operation (unlocking operation) on the second operation unit 26. Is in the house 31 or outside the house 32.

  Here, the 1st operation part 25 is provided in the exterior 32 side of the entrance / exit 4 as mentioned above. That is, the user 5 performs an unlocking operation from the outside 32 on the first operation unit 25. The predetermined condition is, for example, that the entrance door serving as the entrance 4 is once opened and then closed again. In this case, it is estimated that the user 5 has entered the home 31 from the outside 32 through the doorway 4. Accordingly, the determination unit 221 determines that the key device 1 is in the building 3 (home 31) when the above-described conditions are satisfied. However, since it cannot be determined that the key device 1 is necessarily in the home 31 under the above-described conditions alone, the determination unit 221 actually estimates that the key device 1 is in the home 31.

  Moreover, the 2nd operation part 26 is provided in the in-home 31 side of the entrance / exit 4 as mentioned above. That is, the user 5 performs an unlocking operation from the home 31 on the second operation unit 26. The prescribed condition is, for example, that the entrance door serving as the entrance 4 is once opened and then closed again. In this case, it is estimated that the user 5 went out of the house 31 through the doorway 4 to the outside 32. Therefore, the determination unit 221 determines that the key device 1 is outside the building 3 (outside the house 32) when the above-described conditions are satisfied. However, since it cannot be determined that the key device 1 is necessarily outside the home 32 only under the above-described conditions, the determination unit 221 actually estimates that the key device 1 is outside the home 32.

  The mode selection unit 222 is provided in the signal processing unit 22 similarly to the determination unit 221, and the computer functions as the mode selection unit 222 when the CPU executes a program stored in the memory. The mode selection unit 222 is configured to be able to select the operation mode of the electric lock device 2 according to the determination result of the determination unit 221. As an operation mode of the electric lock device 2, “valid mode” for enabling the unlocking operation from the outside 32 by the first operation unit 25, and disabling the unlocking operation from the outside 32 by the first operation unit 25. One of the “invalid modes” is selected. “Effective mode” means that unlocking of the doorway 4 is permitted when the key ID of the key device 1 is successfully authenticated and a predetermined operation (unlocking operation) is performed on the first operation unit 25. It is a mode to do. “Invalid mode” means that the door 4 is unlocked when the key ID of the key device 1 is successfully authenticated and a predetermined operation (unlocking operation) is performed on the first operation unit 25. It is a mode that does not.

  Here, when the determination unit 221 determines that the key device 1 is outside the building 3 (outside the house 32), it is assumed that the user 5 who has the key device 1 is outside the house 32. The unit 222 preferably selects “effective mode” as the operation mode of the electric lock device 2. In this case, since the operation mode of the electric lock device 2 is the “valid mode”, for example, as shown in FIG. 2A, the user 5 who returns home performs an unlocking operation on the first operation unit 25. The doorway 4 can be unlocked. That is, in this embodiment, when the operation mode of the electric lock device 2 is the “valid mode”, the unlocking operation by the first operation unit 25 is accepted.

  On the other hand, when the determination unit 221 determines that the key device 1 is in the building 3 (home 31), it is assumed that the user 5 holding the key device 1 is in the home 31, so the mode selection unit 222 The “invalid mode” is preferably selected as the operation mode of the electric lock device 2. In this case, since the operation mode of the electric lock device 2 is “invalid mode”, for example, as shown in FIG. 2B, a suspicious person 6 who does not specify the key device 1 performs an unlocking operation on the first operation unit 25. Entry / exit 4 is not unlocked even if the operation is performed. That is, in this embodiment, when the operation mode of the electric lock device 2 is the “invalid mode”, the unlocking operation by the first operation unit 25 is not accepted. Thus, when the key device 1 is in the house 31, the operation mode of the electric lock device 2 is set to the “invalid mode”, thereby making it difficult for the entrance / exit 4 of the building 3 to be illegally unlocked from outside the building 3 Can do.

  The storage unit 223 includes a microcomputer memory, for example. The storage unit 223 stores the operation mode of the electric lock device 2 selected by the mode selection unit 222.

(4) Operation Next, the operation of the electric lock system 10 (electric lock device 2) of the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing an operation example of the electric lock system 10 (electric lock device 2). In the following description, it is assumed that the key ID of the key device 1 has been successfully authenticated by communication between the key device 1 and the electric lock device 2.

  The signal processing unit 22 of the electric lock device 2 determines whether or not the first operation has been performed (step ST1). Here, the “first operation” is a predetermined operation (unlocking operation) for the first operation unit 25 performed by the user 5. When the first operation is performed (Yes in step ST1), the signal processing unit 22 determines whether or not the operation mode of the electric lock device 2 is the “valid mode” (step ST2). When the operation mode of the electric lock device 2 is the “valid mode” (Yes in step ST2), the signal processing unit 22 drives the lock of the entrance 4 with the lock drive unit 24 to unlock the entrance 4 (step ST3). ). In other words, the signal processing unit 22 causes the lock driving unit 24 to perform the unlocking process performed by the unlocking operation on the first operation unit 25.

  Thereafter, the determination unit 221 of the signal processing unit 22 determines whether or not the above-described predetermined condition is satisfied (step ST4). When the above-described predetermined condition is satisfied (Yes in step ST4), the determination unit 221 determines (estimates) that the key device 1 is in the building 3 (home 31). And the mode selection part 222 selects "invalid mode" as an operation mode of the electric lock device 2 according to the judgment result of the judgment part 221 (step ST5). That is, in this case, the operation mode of the electric lock device 2 that was in the “valid mode” becomes the “invalid mode”. The operation mode of “invalid mode” selected by the mode selection unit 222 is stored in the storage unit 223. When the operation mode of the electric lock device 2 is “invalid mode” in step ST2, the process returns to step ST1 if the predetermined condition is not satisfied in step ST4.

  When the first operation is not performed in Step ST1 (No in Step ST1), the signal processing unit 22 determines whether or not the second operation is performed (Step ST6). Here, the second operation is a predetermined operation (unlocking operation) on the second operation unit 26 performed by the user 5. When the second operation is performed (Yes in step ST6), the signal processing unit 22 drives the lock of the doorway 4 by the lock driving unit 24 to unlock the doorway 4 (step ST7). Thereafter, the signal processing unit 22 determines whether or not the operation mode of the electric lock device 2 is the “invalid mode” (step ST8). When the operation mode of the electric lock device 2 is the “invalid mode” (Yes in step ST8), the determination unit 221 of the signal processing unit 22 determines whether or not the above-described prescribed condition is satisfied (step ST9). When the above-mentioned prescribed conditions are satisfied (Yes in step ST9), the determination unit 221 determines (estimates) that the key device 1 is outside the building 3 (outside the house 32). Then, the mode selection unit 222 selects “valid mode” as the operation mode of the electric lock device 2 according to the determination result of the determination unit 221 (step ST10). That is, in this case, the operation mode of the electric lock device 2 that was in the “invalid mode” becomes the “valid mode”. The operation mode “effective mode” selected by the mode selection unit 222 is stored in the storage unit 223. If the second operation is not performed in step ST6, the operation mode of the electric lock device 2 is not “invalid mode” in step ST8, or if the prescribed condition is not satisfied in step ST9, the process returns to step ST1. .

  By the way, the key-side communication unit 11 and the lock-side communication unit 21 are continuously communicating in a state where the operation mode of the electric lock device 2 is “valid mode” by satisfying the above-mentioned prescribed conditions. In this case, it is preferable to set the operation mode of the electric lock device 2 to the “invalid mode” again. In this case, since the key device 1 remains within the communication range with the electric lock device 2 although the above-mentioned prescribed conditions are satisfied, the determination unit 221 determines that the key device 1 is in the building 3 (home 31). It can be judged (estimated). Therefore, in this case, it is preferable that the “invalid mode” is selected again as the operation mode of the electric lock device 2 even after the “valid mode” is once selected.

  Further, if the received signal strength does not change for a certain period of time when the operation mode of the electric lock device 2 is in the “valid mode” by satisfying the above specified conditions, the operation of the electric lock device 2 is performed. It is preferable to set the mode to “invalid mode” again. In this case, although the above-mentioned prescribed conditions are satisfied, the received signal strength indicator (RSSI) hardly changes, so that the determination unit 221 has the key device 1 in the building 3 (home 31). It can be judged (estimated). Therefore, in this case, it is preferable that the “invalid mode” is selected again as the operation mode of the electric lock device 2 even after the “valid mode” is once selected. For example, even if the user enters the “valid mode” while staying at home due to a see-off or the like, the “invalid mode” can be set again, thereby ensuring security.

  As described above, the electric lock system 10 of the present embodiment includes the electric lock device 2 and the key device 1. The electric lock device 2 locks the entrance 4 of the building 3. The key device 1 can communicate with the electric lock device 2. The electric lock device 2 includes an operation unit (first operation unit 25), a lock side communication unit 21, and an authentication unit 23. The operation unit is operated from the outside of the building 3 when the doorway 4 is unlocked. The key device 1 includes a key side communication unit 11 that communicates with the lock side communication unit 21. The electric lock system 10 is operated based on the authentication information of the key device 1 received by the lock side communication unit 21 when the operation unit is operated and the lock side communication unit 21 and the key side communication unit 11 communicate with each other. An unlocking process for unlocking the doorway 4 is performed according to the authentication result of the unit 23. The electric lock system 10 further includes a determination unit 221 and a mode selection unit 222. The determination unit 221 determines whether the key device 1 is inside or outside the building 3. The mode selection unit 222 selects an operation mode of an effective mode that enables the unlocking process and an invalid mode that disables the unlocking process according to the determination result of the determination unit 221. According to this configuration, when the determination unit 221 determines that the key device 1 is in the building 3, the unlocking process from outside the building 3 is invalidated by the mode selection unit 222 selecting the invalid mode. Thus, the entrance / exit 4 of the building 3 can be made difficult to be illegally unlocked from the outside of the building 3. Moreover, since the operation mode can be automatically selected by the mode selection unit 222 according to the determination result of the determination unit 221, it is possible to improve security without forgetting to select the operation mode.

  Moreover, like the electric lock system 10 of the present embodiment, the electric lock device 2 may further include a second operation unit 26 that is operated from the inside of the building 3 when the doorway 4 is unlocked. preferable. In this case, the operation unit is the first operation unit 25. And it is preferable that the electric lock device 2 is configured so that the doorway 4 can be unlocked by operating the second operation unit 26 regardless of whether the operation mode is the valid mode or the invalid mode. . According to this configuration, regardless of whether the operation mode of the electric lock system 10 is the valid mode or the invalid mode, the door 4 can be unlocked only by operating the second operation unit 26 from the inside of the building 3. It can be performed. In addition, there is an advantage that it is not necessary to be aware of the operation mode during the unlocking operation from the inside of the building 3. However, this configuration is not an essential configuration of the electric lock system 10, and the second operation unit 26 may be omitted.

  Further, like the electric lock system 10 of the present embodiment, the determination unit 221 determines that the key device 1 is in the building 3 when a predetermined condition is satisfied after the unlocking process is performed. It is preferable that it is comprised. In this case, it is preferable that the mode selection unit 222 is configured to select the invalid mode as the operation mode. According to this configuration, when the unlocking process is performed from outside the building 3, it is assumed that the user 5 has entered the building 3. It is possible to make it difficult for the doorway 4 to be illegally unlocked from the outside of the building 3. However, this configuration is not an essential configuration of the electric lock system 10, and is configured to set the operation mode to the invalid mode when a predetermined condition is satisfied after the unlocking process from outside the building 3 is performed. It does not have to be.

  In addition, as in the electric lock system 10 of the present embodiment, the determination unit 221 determines that the specified condition is satisfied after the second operation unit 26 is operated and the doorway 4 is unlocked. Preferably, the device 1 is configured to determine that it is outside the building 3. In this case, it is preferable that the mode selection unit 222 is configured to select the effective mode as the operation mode. According to this configuration, when the doorway 4 is unlocked from the inside of the building 3, it is assumed that the user 5 goes out of the building 3, so the operation mode is set to the effective mode. The unlocking process can be performed from outside the building 3 when the user 5 returns home. However, this configuration is not an essential configuration of the electric lock system 10, and is configured to set the operation mode to the effective mode when the specified conditions are satisfied after the unlocking process is performed from the inside of the building 3. It does not have to be.

  The electric lock device 2 of the present embodiment locks the entrance / exit 4 of the building 3. The electric lock device 2 includes an operation unit (first operation unit 25), a lock side communication unit 21, and an authentication unit 23. The operation unit is operated from the outside of the building 3 when the doorway 4 is unlocked. In the electric lock device 2, the operation unit is operated, and the lock side communication unit 21 communicates with the key side communication unit 11 of the key device 1, so that the lock side communication unit 21 receives the authentication information of the key device 1. It is configured to perform an unlocking process for unlocking the entrance 4 according to the authentication result of the authentication unit 23 based. The electric lock device 2 further includes a determination unit 221 and a mode selection unit 222. The determination unit 221 determines whether the key device 1 is inside or outside the building 3. The mode selection unit 222 selects an operation mode of an effective mode that enables the unlocking process and an invalid mode that disables the unlocking process according to the determination result of the determination unit 221. According to this configuration, when the determination unit 221 determines that the key device 1 is in the building 3, the unlocking process from outside the building 3 is disabled by the mode selection unit 222 selecting the invalid mode. Thus, the entrance / exit 4 of the building 3 can be made difficult to be illegally unlocked from the outside of the building 3. Moreover, since the operation mode can be automatically selected by the mode selection unit 222 according to the determination result of the determination unit 221, it is possible to improve security without forgetting to select the operation mode.

  Hereinafter, modifications of the present embodiment will be described.

  The building 3 is not limited to a detached house, but may be a house other than a detached house such as each dwelling unit of a housing complex, or a non-residential such as an office, a store, or a nursing facility.

  Further, the key device 1 is not limited to the tag-like device as in the above-described embodiment, and may be, for example, an IC card or the like, or may be configured by a general-purpose terminal such as a smartphone. Good.

  Furthermore, the communication method between the key device 1 and the electric lock device 2 is not limited to Bluetooth (registered trademark), but may be other wireless communication using a radio wave as a medium, or optical communication using a light such as infrared light as a medium. There may be.

  In the above-described embodiment, the key ID authentication is performed by the electric lock device 2. However, the present invention is not limited to this example. For example, the key device 1 may perform the key ID authentication. In other words, when the lock ID stored in advance in the electric lock device 2 is transmitted from the electric lock device 2 to the key device 1, the lock ID and the key ID are collated in the key device 1, and the two match. The authentication signal may be transmitted to the electric lock device 2. In this case, the electric lock device 2 receives the authentication signal from the key device 1 so that the doorway 4 can be unlocked.

  Furthermore, in the above-described embodiment, the determination unit 221 is provided in the electric lock device 2, but the determination unit may be provided in the key device 1. In this case, opening / closing information of the entrance door serving as the entrance / exit 4 is transmitted from the electric lock device 2 to the key device 1, and based on the opening / closing information, the key device 1 determines whether the key device 1 is in the building 3. Judge whether it is outside or not. Then, the determination result of the determination unit is transmitted from the key device 1 to the electric lock device 2, and the mode selection unit 222 of the electric lock device 2 selects the operation mode of the electric lock device 2 based on the determination result.

  In the above-described embodiment, the key ID authentication process of the key device 1 is performed before a predetermined operation (unlocking operation) is performed on the first operation unit 25. After the above operation is performed, the key ID authentication process may be performed.

  Further, in the above-described embodiment, when the operation mode of the electric lock device 2 is “invalid mode”, the unlock operation by the first operation unit 25 is not accepted. The key ID to be transmitted may not be received. When the key ID is not received, authentication processing is not performed in the authentication unit 23, so that the doorway 4 is not unlocked even if the first operation unit 25 is unlocked. As a result, similarly to the above-described embodiment, the entrance / exit 4 of the building 3 can be prevented from being illegally unlocked from the outside of the building 3. Further, when the operation mode corresponding to the key device 1 that has transmitted the response signal to the connection request signal is the “invalid mode”, the response signal may not be received.

  In the above-described embodiment, the operation mode of the electric lock device 2 has been described as an example, but the operation mode of the key device 1 may be used. In this case, if the operation mode of the key device 1 is the “invalid mode”, the connection request signal transmitted from the electric lock device 2 may not be received, and the ID request signal may not be received. It may be configured. Furthermore, an ID signal may not be transmitted in response to an ID request signal transmitted from the electric lock device 2. In any case, similarly to the above-described embodiment, the entrance / exit 4 of the building 3 can be made difficult to be illegally unlocked from the outside of the building 3.

  Furthermore, the operation mode described above may include both the operation mode of the key device 1 and the operation mode of the electric lock device 2. In this case, according to the determination result of the determination unit 221, both the operation mode of the key device 1 and the operation mode of the electric lock device 2 are simultaneously selected by the mode selection unit 222.

  Further, in the above-described embodiment, there is one key device 1, but a plurality of key devices 1 may be provided. In this case, the operation mode for setting “valid” and “invalid” of the unlocking process from outside the building 3 has a plurality of operation modes so as to correspond to the plurality of key devices 1 on a one-to-one basis. It is preferable. In other words, it is preferable that the electric lock system 10 includes a plurality of key devices 1 and has a plurality of operation modes associated with the plurality of key devices 1 on a one-to-one basis. According to this configuration, the operation mode can be individually set for each of the plurality of key devices 1. However, this configuration is not an essential configuration of the electric lock system 10 and may be configured such that one operation mode corresponds to the plurality of key devices 1.

  Further, when a plurality of key devices 1 are used, if the key side communication unit 11 of the plurality of key devices 1 is in an area where it can communicate with the lock side communication unit 21 of the electric lock device 2, the plurality of key devices 1. It is preferable that a plurality of operation modes associated one-to-one are selected at once. In other words, in the electric lock system 10, the mode selection unit 222 is configured to collectively select a plurality of operation modes when the plurality of key side communication units 11 and the lock side communication unit 21 can communicate. It is preferable. According to this configuration, for example, when a plurality of users 5 enter the building 3 together, the plurality of operation modes associated with the plurality of key devices 1 on a one-to-one basis are set to the same mode. There is an advantage that the nature is not impaired. However, this configuration is not an indispensable configuration of the electric lock system 10, and is configured to select a plurality of operation modes at once when the plurality of key side communication units 11 and the lock side communication unit 21 can communicate with each other. It does not have to be.

  Further, the “predetermined condition” and the “specified condition” in the above-described embodiment are examples. For example, the received signal strength may be used for the “predetermined condition” and the “specified condition”. In this case, when the received radio wave intensity that has become stronger due to approaching the entrance / exit 4 becomes weaker by moving away from the entrance / exit 4, it may be determined that the “predetermined condition” and the “specified condition” are satisfied. Further, the “predetermined condition” and the “prescribed condition” may be the same as in the above-described embodiment and this modification, or may be different.

  By the way, when the key device 1 is a device having a telephone function such as a smartphone, for example, by calling the key device 1 in the home 31 from the key device 1 outside the home 32, the operation mode of the electric lock device 2 is set to “valid” The “mode” may be selected. For example, when the user 5 forgets the key device 1 in the house 31 and the operation mode of the electric lock device 2 is “invalid mode”, even the user 5 can enter the entrance 4 from outside the building 3. Unlocking is not possible. Therefore, it is preferable that the operation mode can be switched by the telephone function so that the doorway 4 can be unlocked from outside the building 3 even in such a case.
