(Embodiment 1)
(1) Outline Hereinafter, when describing the electric lock device 1 and the electric lock system 100 of the first embodiment, first, an outline of the electric lock system 100 of the present embodiment will be described. The electric lock system 100 of the present embodiment includes an electric lock device 1 and a key device 2 as shown in FIG.

  The electric lock device 1 is a device that locks the entrance 4 of the building 3 as shown in FIG. The entrance 4 is a door or a window that separates the inside of the building 3 (inside the house 31) from the outside (outside the house 32), and is, for example, an entrance door, a service entrance, or a sweep window. The electric lock device 1 is installed at the entrance 4. The electric lock device 1 is configured to be able to communicate with the key device 2. The electric lock device 1 is configured to electrically switch 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 2.

  The key device 2 has a communication function with the electric lock device 1. In the present embodiment, the communication method between the electric lock device 1 and the key device 2 is wireless communication using radio waves as a medium. In the present embodiment, the electric lock device 1 and the key device 2 are both battery-driven. Further, in the present embodiment, the key device 2 is configured in a tag shape that can be attached to a bag or the like carried by the user 5. In the present embodiment, a case where the building 3 is a detached house will be described as an example. Therefore, the user 5 is a person who owns the key device 2 among the residents of the building 3.

  In the electric lock system 100, the key device 2 transmits a terminal ID (Identification) stored in the key device 2 in advance toward the electric lock device 1 to lock or unlock the entrance 4 of the electric lock device 1. Enable tablets. In other words, when the electric lock device 1 and the key device 2 communicate with each other in a state where the connection is established and the terminal ID of the key device 2 is successfully authenticated, the electric lock device 1 locks or unlocks the entrance 4. It is possible. In the present embodiment, the electric lock device 1 performs authentication after an operation input by the user 5 on the electric lock device 1 or an operation input by the user 5 on the key device 2. Then, when the authentication is successful, the electric lock device 1 locks (or unlocks) the entrance 4. That is, the electric lock device 1 performs an unlocking operation for switching from the locked state to the unlocked state or a locking operation for switching from the unlocked state to the locked state through communication with the key device 2.

(2) Configuration Hereinafter, the configurations of the electric lock device 1 and the key device 2 in the electric lock system 100 of the present embodiment will be described in detail with reference to FIGS.

  As shown in FIG. 1, the electric lock device 1 includes a lock-side communication unit 11, a lock-side operation unit 12, a lock drive unit 13, a lock-side control unit 14, and a battery 15. The electric lock device 1 is built in, for example, a door (for example, an entrance door) serving as an entrance 4. The battery 15 is a secondary battery and serves as a power supply for operating the electric lock device 1. The battery 15 may be included in the components of the electric lock device 1 or may not be included in the components of the electric lock device 1.

  The lock side communication unit 11 is configured to be able to communicate with the key device 2 (key side communication unit 21 described later). The communication method between the lock side communication unit 11 and the key side communication unit 21 is wireless communication using radio waves such as Bluetooth (registered trademark) as a medium. In the present embodiment, the electric lock device 1 not only transmits a signal to the key device 2 but also receives a signal such as a response signal (ACK: ACKnowledgement) from the key device 2. Therefore, the lock-side communication unit 11 has a signal transmission function and a signal reception function, and is configured to perform bidirectional communication with the key-side communication unit 21.

  The lock-side operation unit 12 has a function of receiving an operation input by the user 5 (that is, a person). The lock-side operation unit 12 is composed of, for example, push-button switches provided on the entrance 31 side of the entrance 31 and the exterior 32 side. In addition, the lock-side operation unit 12 may be, for example, a door handle (handle) provided on the door of the entrance 4, or may be a touch sensor or the like that detects an operation of the user 5 touching the door handle. When the lock operation unit 12 receives an operation input, an operation signal corresponding to the operation input is transmitted to the lock control unit 14.

  The lock drive unit 13 is configured to electrically lock or unlock a lock (dead bolt) provided at the entrance 4 of the building 3. Specifically, the lock drive unit 13 has a drive motor controlled by the lock control unit 14. The lock drive unit 13 is configured to move the dead bolt by transmitting the driving force of the drive motor to the dead bolt. When at least a part of the deadbolt is at a position protruding from the door, the door is locked. Also, when the entire dead bolt is housed in the door, the door is unlocked.

  In the present embodiment, the lock-side control unit 14 is configured by a microcomputer having a CPU (Central Processing Unit) and a memory as main components. In other words, the lock-side control unit 14 is realized by a computer having a CPU and a memory, and the computer functions as the lock-side control unit 14 when the CPU executes a program stored in the memory. Here, the program is recorded in advance in the memory of the microcomputer, but may be provided through an electric communication line such as the Internet, or recorded on a recording medium such as a memory card.

  At least one registration ID is registered (stored) in the memory of the lock-side control unit 14. The registration ID corresponds to the terminal ID of the key device 2. For example, when there are a plurality of residents of the building 3 and each possesses a separate key device 2 (that is, when the electric lock system 100 includes a plurality of key devices 2), the memory of the lock-side control unit 14 A plurality of registration IDs corresponding to the terminal IDs of the plurality of key devices 2 are registered.

  The lock control unit 14 controls the lock communication unit 11 and the lock drive unit 13. In the present embodiment, the lock-side control unit 14 is configured to execute the first mode and the second mode by controlling the lock-side communication unit 11. The first mode is a mode that is executed until an operation input from the lock operation unit 12 is received. That is, the first mode is always executed during the operation of the electric lock device 1 except for the period during which the second mode is executed. The second mode is a mode executed when the lock operation unit 12 receives an operation input and the operation input is used as a trigger. That is, the second mode is a process executed only when the electric lock device 1 receives an operation input by the user 5.

  In the first mode, the lock control unit 14 periodically executes a first transmission process and a first reception process. The first transmission process is a process of causing the lock-side communication unit 11 to transmit an inquiry signal for inquiring the key device 2 whether or not there is a command. Here, the command is a command for causing the electric lock device 1 to execute a specific process in response to an operation input by the user 5 on the key device 2. The first reception process is a process of controlling the lock-side communication unit 11 to a reception state of waiting for a signal for a predetermined time after the first transmission process. That is, in the first mode, the lock-side control unit 14 periodically repeats the process of transmitting the interrogation signal and waiting for the signal for a certain period of time. In the present embodiment, in the first mode, the lock-side control unit 14 repeats the first transmission process and the first reception process every few seconds (for example, every one second).

  In the second mode, the lock-side control unit 14 executes the second transmission processing and the second reception processing irrespective of the cycles of the first transmission processing and the first reception processing. The second transmission process is a process of transmitting a connection request signal for requesting connection with the key device 2 from the lock-side communication unit 11. The second reception process is a process of controlling the lock-side communication unit 11 to be in a reception state for a certain time after the second transmission process. In the present embodiment, the lock control unit 14 repeats the second transmission process and the second reception process every several tens of ms (for example, 20 ms) until a response signal from the key device 2 is received.

  When the lock-side communication unit 11 receives a response signal from the key device 2 in the receiving state and the connection between the electric lock device 1 and the key device 2 is established, the lock-side control unit 14 executes the authentication mode. In the authentication mode, the lock controller 14 causes the lock communication unit 11 to transmit an authentication request signal for requesting the terminal ID to the key device 2. Next, the lock control unit 14 causes the lock communication unit 11 to receive a response signal including the terminal ID from the key device 2. Then, the lock-side control unit 14 checks the terminal ID included in the received signal against a previously stored registration ID.

  If the terminal ID matches the registered ID and the authentication is successful, the lock control unit 14 executes a specific process according to an operation input on the lock operation unit 12 or a command from the key device 2. In the present embodiment, the specific processing executed by the lock-side control unit 14 is locking or unlocking of the entrance 4 by controlling the lock driving unit 13.

  As shown in FIG. 1, the key device 2 includes a key-side communication unit 21, a key-side control unit 22, a key-side operation unit 23, and a battery 24, and these are placed in a portable case. It is housed and configured. The battery 24 is a secondary battery and serves as a power supply for operating the key device 2. The battery 24 may be included in a component of the key device 2 or may not be included in a component of the key device 2.

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

  When the key device 2 exists in the communication area 6 (see FIG. 2) (that is, when the user 5 carrying the key device 2 exists in the communication area 6), the key-side communication unit 21 Communicable with the lock-side communication unit 11. The communication area 6 referred to here is a range in which communication between the electric lock device 1 and the key device 2 is possible based on the electric lock device 1, that is, a communication area between the electric lock device 1 and the key device 2. Set to the range where radio waves can reach.

  The key-side control unit 22 is configured by, for example, a microcomputer, and controls the key-side communication unit 21. The memory of the key-side control unit 22 stores a terminal ID unique to the key device 2. When the key-side communication unit 21 receives the inquiry signal from the electric lock device 1 in a state where the key-side operation unit 23 receives the operation input, the key-side control unit 22 transmits a response signal to the inquiry signal to the key-side communication unit 21. To send from. On the other hand, when the key-side communication unit 21 receives the inquiry signal from the electric lock device 1 in a state where the key-side operation unit 23 has not received an operation input, the key-side control unit 22 transmits the response signal to the key-side communication unit. No transmission from 21.

  When the key-side communication unit 21 receives the connection request signal from the electric lock device 1, the key-side control unit 22 causes the key-side communication unit 21 to transmit a response signal to the connection request signal. When the key-side communication unit 21 receives the authentication request signal from the electric lock device 1, the key-side control unit 22 sends a signal including the terminal ID stored in the memory to the key-side as a response signal to the authentication request signal. It is transmitted from the communication unit 21.

  The key-side operation unit 23 has a function of receiving an operation input by the user 5. The key-side operation unit 23 includes, for example, a push-button switch provided in a case of the key device 2. In addition, the key-side operation unit 23 may be configured by, for example, a lever provided in a case of the key device 2 or may be configured by a touch panel. When the key operation unit 23 receives an operation input, an operation signal corresponding to the operation input is transmitted to the key control unit 22.

(3) Operation Hereinafter, the operation of the electric lock device 1 and the electric lock system 100 of the present embodiment will be described.

  First, a case where the user 5 operates the key device 2 to unlock the entrance 4 will be described with reference to FIG. In the example illustrated in FIG. 3, it is assumed that no operation input has been performed on the electric lock device 1.

  When the power of the electric lock device 1 is turned on, the lock control unit 14 starts the first mode. That is, the lock-side control unit 14 repeats the first transmission process of transmitting the interrogation signal (step S11) and the first reception process (step S12) of waiting for a certain time T11 and a signal at a certain cycle T1. Until the user 5 operates the key device 2, the key device 2 does not respond to the interrogation signal even if the key device 2 exists in the communication area 6.

  When the user 5 operates the key device 2 at an arbitrary timing, that is, when the key-side operation unit 23 receives an operation input, the key-side control unit 22 sets a flag indicating that the operation input has been received (step S13). When the key-side communication unit 21 receives the inquiry signal with this flag set, the key-side control unit 22 causes the key-side communication unit 21 to transmit a response signal to the inquiry signal (step S14). Here, the response signal is transmitted from the key-side communication unit 21 at a timing specified based on the timing at which the key-side communication unit 21 receives the interrogation signal. Therefore, the lock-side communication unit 11 can receive the response signal while the lock-side control unit 14 is executing the first reception process (step S12), that is, in the reception state.

  When the lock side communication unit 11 receives the response signal, the lock side control unit 14 ends the first mode and starts the authentication mode (step S15). In the present embodiment, the command from the key device 2 is included in the response signal to the authentication request signal and transmitted in the authentication mode. Then, when the authentication is successful, the lock-side control unit 14 executes a specific process according to a command from the key device 2. Here, the lock-side control unit 14 unlocks the entrance 4 by controlling the lock drive unit 13 (step S16). After the execution of the specific process, the lock-side control unit 14 restarts the first mode.

  Next, a case where the user 5 operates the electric lock device 1 to unlock the entrance 4 will be described with reference to FIG. In the example illustrated in FIG. 4, it is assumed that no operation input has been performed on the key device 2.

  When the power of the electric lock device 1 is turned on, the lock control unit 14 starts the first mode. That is, the lock-side control unit 14 repeats the first transmission process of transmitting the interrogation signal (step S21) and the first reception process of waiting for the signal for a fixed time T11 (step S22) at a fixed cycle T1.

  When the user 5 operates the electric lock device 1 at an arbitrary timing, that is, when the lock operation unit 12 receives an operation input (step S23), the lock control unit 14 ends the first mode and switches to the second mode. Start. That is, the lock-side control unit 14 repeats the second transmission process of transmitting the connection request signal (step S24) and the second reception process of waiting for a signal for a fixed time T21 (step S25) at a fixed cycle T2. Here, the cycle T2 of the second transmission processing and the second reception processing is shorter than the cycle T1 of the first transmission processing and the second reception processing.

  In the key device 2 existing in the communication area 6, when the key side communication unit 21 receives the connection request signal, the key side control unit 22 causes the key side communication unit 21 to transmit a response signal to the connection request signal (step S26). ). Here, the response signal is transmitted from the key-side communication unit 21 at a timing specified based on the timing at which the key-side communication unit 21 receives the connection request signal. Therefore, the lock side communication unit 11 can receive the response signal while the lock side control unit 14 is executing the second reception process (step S25), that is, in the reception state.

  When the lock side communication unit 11 receives the response signal, the lock side control unit 14 ends the second mode and starts the authentication mode (Step S27). If the authentication is successful, the lock-side control unit 14 executes a specific process according to the operation input on the lock-side operation unit 12. Here, the lock-side control unit 14 unlocks the entrance 4 by controlling the lock drive unit 13 (step S28). After the execution of the specific process, the lock-side control unit 14 restarts the first mode.

  Although the case where the user 5 operates the electric lock device 1 or the key device 2 to unlock the entrance 4 has been described, the same applies to the case where the entrance 4 is locked. In this case, when the authentication is successful, the lock-side control unit 14 controls the lock drive unit 13 to lock the entrance 4.

(4) Effect Normally, in the electric lock system, the electric lock device receives the response signal from the key device regardless of whether the user operates the electric lock device or the user operates the key device. You have to wait for a signal to do so. However, when the electric lock device is always in a state of waiting for a signal (reception state), it is necessary to always start the communication unit, so that power consumption increases. Therefore, it is conceivable to suppress power consumption by intermittently starting the communication unit. However, in this case, a delay occurs in receiving the response signal from the key device, and the response to the user's operation may be impaired.

  Therefore, in the electric lock device 1 of the present embodiment, the lock-side control unit (control unit) 14 executes the second mode when receiving an operation input from the lock-side operation unit (operation unit) 12, and in other cases, Are configured to execute a first mode. That is, in the electric lock device 1 of the present embodiment, the lock-side communication unit (communication unit) 11 performs the intermittent reception by repeatedly executing the first transmission process and the first reception process at a relatively long cycle. It is possible to wait for a command from the key device 2 while suppressing power consumption in the lock device 1. When the user 5 operates the electric lock device 1, the second mode is executed regardless of the periods of the first transmission process and the first reception process, so that the connection with the key device 2 can be performed in a relatively short time.・ Authentication can be performed. Therefore, in the electric lock device 1 and the electric lock system 100 of the present embodiment, the power consumption of the electric lock device 1 can be suppressed, and the responsiveness to the operation of the user 5 is not easily impaired.

  Here, in the electric lock system 100 of the present embodiment, by increasing the period of the intermittent reception of the lock side communication unit (communication unit) 11, the response speed to the operation of the key device 2 by the user 5 is slightly delayed. It seems that there is no problem. This is because in the electric lock system 100 of the present embodiment, it is assumed that the key device 2 is operated at a position relatively far from the entrance 4. Since the time from when the user 5 operates the key device 2 to when the user 5 reaches the entrance 4 is relatively long, the responsiveness is impaired even if the response speed is slower than the operation input in the electric lock device 1. Because it is difficult.

<Modification>
By the way, in the present embodiment, the signal strength of the interrogation signal may be higher than the signal strength of the connection request signal. In other words, the signal strength of the connection request signal may be kept smaller than the signal strength of the interrogation signal. In this case, the reach of the connection request signal originating from the electric lock device 1 is limited, so that security can be improved. For example, when another person other than the user 5 performs an operation input with the electric lock device 1, a connection / authentication with the key device 2 of the user 5 which is accidentally located relatively far from the electric lock device 1 is performed. It becomes easier to prevent the situation of going. Further, by suppressing the transmission output of the connection request signal to a low level, an effect of suppressing power consumption in the electric lock device 1 can be expected.

  Further, in the present embodiment, the lock-side control unit 14 of the electric lock device 1 controls the response signal (the response signal to the connection request signal) from the key device 2 until a predetermined period has elapsed since the start of the second mode. ) May be configured to end the second mode if the second mode cannot be received.

  Hereinafter, a case where a response signal from the key device 2 cannot be received after the user 5 operates the electric lock device 1 will be described with reference to FIG. In the example shown in FIG. 5, it is assumed that the key device 2 does not exist in the communication area 6. Such a situation may occur, for example, when the user 5 who operates the electric lock device 1 does not carry the key device 2.

  When the power of the electric lock device 1 is turned on, the lock control unit 14 starts the first mode. That is, the lock-side control unit 14 repeats the first transmission process of transmitting the interrogation signal (step S31) and the first reception process of waiting for the signal for a fixed time T11 (step S32) at a fixed cycle T1.

  When the user 5 operates the electric lock device 1 at an arbitrary timing, that is, when the lock operation unit 12 receives an operation input (step S33), the lock control unit 14 ends the first mode and switches to the second mode. Start. That is, the lock-side control unit 14 repeats the second transmission process of transmitting the connection request signal (step S34) and the second reception process (step S35) of waiting a signal for a certain period of time T2 at a certain period T2.

  The lock-side control unit 14 repeats the second transmission process and the second reception process until a predetermined period T22 has elapsed since the start of the second mode, but when the predetermined period T22 has elapsed, the key device 2 If the response signal is not received, the second mode is ended. Then, the lock control unit 14 restarts the first mode, and repeats the first transmission process (step S31) and the first reception process (step S32) at a constant cycle T1.

  With this configuration, when the key device 2 is not present in the communication area 6, the transmission of the unilateral signal from the electric lock device 1 can be prevented from being uselessly continued. Power consumption can be suppressed.

  In the present embodiment, the key device 2 is a tag-shaped device, but may be, for example, an IC card or a general-purpose information terminal such as a smartphone or a PDA (Personal Digital Assistant).

  Here, in the present embodiment, the lock-side control unit 14 of the electric lock device 1 performs locking or unlocking by either an operation input on the electric lock device 1 or a command from the key device 2. , And other configurations. That is, of the specific processing, the specific processing performed by the lock-side control unit (control unit) 14 in response to an operation input on the electric lock device 1 and the specific processing performed by the lock-side control unit 14 in response to a command from the key device 2 The specific processing to be performed may be different from each other.

  For example, it is assumed that the key device 2 is a general-purpose information terminal such as a smartphone and has a display (display unit). In this case, in response to a command from the key device 2, the lock-side control unit 14 of the electric lock device 1 transmits information on the state (locked state or unlocked state) of the electric lock device 1 from the lock-side communication unit 11 to the key device. 2 may be transmitted. With this configuration, the user 5 can check the state of the electric lock device 1 by looking at the display of the key device 2. In addition, the lock-side control unit 14 of the electric lock device 1 sends information on the locking or unlocking history of the electric lock device 1 from the lock-side communication unit 11 to the key device 2 in response to a command from the key device 2. You may make it transmit. In this configuration, the user 5 can check the lock / unlock history of the electric lock device 1 by looking at the display of the key device 2.

  Further, in the present embodiment, the building 3 is a detached house, but may be a house other than the detached house such as each dwelling unit of an apartment house. The building 3 may be a non-residential house such as an office, a store, or a nursing facility.

  In the present embodiment, the communication method between the electric lock device 1 and the key device 2 is Bluetooth (registered trademark). However, other wireless communication using radio waves or light such as infrared light is used as a medium. Optical communication or the like.

  The batteries 15 and 24 used in each of the electric lock device 1 and the key device 2 are not limited to secondary batteries, but may be, for example, primary batteries or solar batteries.

  In the present embodiment, the lock-side control unit 14 checks the registration ID and the terminal ID in the authentication mode, but may check the key information further. The key information is unique information of the electric lock device 1 issued by the electric lock device 1. The key information is stored in each of the electric lock device 1 and the key device 2 registered in the electric lock device 1 in advance. In this case, the lock-side control unit 14 requests the key device 2 for key information in addition to the terminal ID in the authentication mode. Then, the lock-side control unit 14 checks the registered ID with the terminal ID, and checks the key information stored in advance with the key information obtained from the key device 2, and if all match, the authentication is successful. It is determined that it has been performed.

  Further, in the present embodiment, the authentication of the terminal ID is performed by the electric lock device 1, but may be performed by the key device 2. In this case, the lock-side controller 14 of the electric lock device 1 causes the registration ID stored in advance to be transmitted from the lock-side communication unit 11 to the key device 2 in the authentication mode. The key-side control unit 22 of the key device 2 checks the acquired registration ID with the terminal ID stored in advance (otherwise, checks key information). The data is transmitted from the communication unit 21 to the electric lock device 1. When the lock-side communication unit 11 receives the authentication signal from the key device 2, the lock-side control unit 14 of the electric lock device 1 responds to an operation input from the lock-side operation unit 12 or a command from the key device 2. Perform specific processing.

  Further, in the present embodiment, the command from the key device 2 is transmitted in the authentication mode in a response signal to the authentication request signal, but may be transmitted in another signal. For example, the command from the key device 2 may be transmitted as included in a response signal to the inquiry signal. In addition, the command from the key device 2 may be transmitted after the authentication mode.

(Embodiment 2)
Hereinafter, the electric lock device 1 and the electric lock system 100 according to the second embodiment will be described. However, since the basic configurations of the electric lock device 1 and the electric lock system 100 of the present embodiment are common to the electric lock device 1 and the electric lock system 100 of the first embodiment, description of common points is omitted. I do. The configuration described in the present embodiment can be applied in appropriate combination with the configuration (including the modification) described in the first embodiment.

  When the key device 2 is a general-purpose information terminal such as a smartphone, the key device 2 may be in a power saving state (suspend state) in order to suppress consumption of the battery 24. In this case, for example, if the key device 2 does not return to the active state from the power saving state when the user 5 operates the electric lock device 1, the key-side communication unit 21 of the key device 2 The connection request signal may not be received. For this reason, the time from the time when an operation input is generated in the electric lock device 1 to the time when a specific process (for example, locking or unlocking) is executed becomes longer, and the responsiveness to the operation of the electric lock device 1 by the user 5 is reduced. Could be impaired.

  Therefore, in the present embodiment, the lock-side control unit (control unit) 14 is configured to execute the third mode in addition to the first mode and the second mode. The third mode is a mode in which an activation signal for releasing the power saving state of the key device 2 is transmitted from the lock-side communication unit (communication unit) 11 at a cycle shorter than the transmission cycle of the inquiry signal. The activation signal is a signal that is unilaterally transmitted from the electric lock device 1 to the key device 2 and is a signal that causes the key device 2 in the power saving state to react and release the power saving state. The content does not matter. In the third mode, the lock-side control unit 14 transmits an activation signal every several hundred ms (for example, 100 ms) in parallel with the first mode or the second mode. The transmission cycle of the activation signal is preferably shorter than the transmission cycle of the interrogation signal and longer than the transmission cycle of the connection request signal.

  Hereinafter, a case where the user 5 operates the electric lock device 1 to unlock the entrance 4 will be described with reference to FIG. In the example shown in FIG. 6, only the sequences of the second mode and the third mode are illustrated, and the illustration of the sequence of the first mode is omitted. In the example shown in FIG. 6, it is assumed that the key device 2 is not present in the communication area 6 and is in a power saving state when the electric lock device 1 is turned on.

  When the power of the electric lock device 1 is turned on, the lock-side control unit 14 starts the third mode in parallel with the first mode. That is, the lock-side control unit 14 repeats the process of transmitting the activation signal from the lock-side communication unit 11 at a constant cycle T3 (step S41). Here, since the key device 2 has not yet reached the communication area 6, the key-side communication unit 21 cannot receive the activation signal. Therefore, here, the key device 2 remains in the power saving state.

  When the key device 2 reaches the communication area 6 (step S42), the key-side communication unit 21 can receive the activation signal. Therefore, when the key-side communication unit 21 receives the next activation signal after the key device 2 reaches the communication area 6, the key device 2 returns from the power saving state to the active state (step S43).

  Thereafter, when the user 5 operates the electric lock device 1 at an arbitrary timing, that is, when the lock-side operation unit 12 receives an operation input (step S44), the lock-side control unit 14 ends the first mode and ends the second mode. Enter mode. That is, the lock-side controller 14 repeats the second transmission process of transmitting the connection request signal (step S45) and the second reception process of waiting for the signal for a fixed time T21 (step S46) at a fixed cycle T2.

  Since the key device 2 has already returned to the active state, the key-side communication unit 21 can receive the connection request signal. When the key-side communication unit 21 receives the connection request signal, the key-side control unit 22 causes the key-side communication unit 21 to transmit a response signal to the connection request signal (step S47).

  When the lock side communication unit 11 receives the response signal, the lock side control unit 14 ends the second mode and executes the authentication mode (step S48). If the authentication is successful, the lock-side control unit 14 executes a specific process according to the operation input on the lock-side operation unit 12. Here, the lock side control unit 14 unlocks the entrance 4 by controlling the lock drive unit 13 (step S49). After the execution of the specific process, the lock-side control unit 14 restarts the first mode.

  Here, it is also conceivable to configure the lock-side control unit 14 so that the lock-side operation unit 12 causes the lock-side communication unit 11 to transmit an activation signal after receiving an operation input. However, in this configuration, since it takes time for the key device 2 to return from the power saving state to the active state, a period occurs in which the key side communication unit 21 cannot receive the connection request signal. As a result, the time from when the operation input is generated in the electric lock device 1 to when the specific processing is executed becomes longer, and the responsiveness to the operation of the electric lock device 1 by the user 5 may be impaired.

  In the present embodiment, the lock-side control unit 14 executes the third mode in parallel with the first mode. For this reason, in this embodiment, if the key device 2 reaches the range (communication area 6) where the activation signal can reach, the key device 2 is returned to the active state in advance before the lock operation unit 12 receives an operation input. Is possible. Therefore, in the present embodiment, even when the key device 2 is a general-purpose information terminal such as a smartphone, the time from when an operation input is performed on the electric lock device 1 to when the specific process is performed becomes longer. Can be prevented. As a result, in the present embodiment, the responsiveness to the operation of the electric lock device 1 by the user 5 is not easily impaired.

The second transmission process is a process of transmitting a connection request signal for requesting connection with the key device 2 from the lock-side communication unit 11. The second reception process is a process of controlling the lock-side communication unit 11 to be in a reception state for a certain time after the second transmission process.

  According to this configuration, since the lock side communication unit 11 performs intermittent reception by repeatedly executing the first transmission process and the first reception process at a relatively long cycle, it is possible to suppress power consumption in the electric lock device 1. it can. In addition, when the user 5 operates the electric lock device 1, the responsiveness to the operation of the user 5 is not easily impaired by executing the second mode regardless of the cycles of the first transmission process and the first reception process. .
