By the way, some of the above electronic keys are provided with an operation switch for locking and unlocking. In the locking/unlocking system using the electronic key, an operation signal is transmitted from the electronic key by operating the operation switch, and locking/unlocking at a position apart from the locking device is possible. Therefore, when the user enters the building, the locking device can be unlocked by remote control, which is convenient.

However, if the electronic key is placed near the entrance, for example, if a child mistakenly performs the unlocking operation, the entrance door is unintentionally unlocked.

The present invention has been made in view of the above circumstances, and provides a locking/unlocking system for a building capable of suppressing an unexpected unlocking by remote control indoors and improving convenience. With the goal.

In order to solve the above problems, the first invention is applied to a building provided with a door body for opening and closing a doorway of the building and a locking device for locking the door body, and is portable by a user. A remote operation device that is provided with an operation unit for locking and unlocking the locking device and that transmits an operation signal based on the operation of the operation unit, and a reception that can receive the operation signal transmitted from the remote operation device. A device, a control means for controlling locking and unlocking of the locking device based on the operation signal received by the receiving device, and a person detecting means for detecting the presence of a person near the doorway in the building, The control means, when the presence of a person is detected by the person detecting means in a predetermined period after unlocking the locking device or after opening the door body, the remote control based on the operation signal thereafter. It is characterized in that it comprises an invalidating means for invalidating the lock operation.

According to the first aspect of the invention, there is provided a person detecting means for detecting the presence of a person near the doorway in the building.

For this reason, when a plurality of remote operation devices are used, the remote operation device approaching the entrance can be specified. Moreover, in the present invention, the remote unlocking operation of the remote operation device specified by the specifying means is invalidated. Therefore, it is possible to invalidate the remote unlocking operation targeting the remote control device approaching the doorway. As a result, when the timing of entering a building is mixed among a plurality of users, the user who first entered the building disables the remote unlocking operation, and as a result, a user who later enters the building cannot remotely unlock the building. The inconvenience can be preferably solved.

In a fifth aspect, the locking device is provided with an unlocking operation unit for unlocking the locking device by a manual operation from the inside of the building, and the control unit includes the unlocking operation unit. When the locking device is unlocked by being operated, it is provided with a releasing means for releasing the invalidation of the remote unlocking operation performed by the invalidating means.

In the fifth invention, when the locking device is unlocked by the operation of the unlocking operation unit, it is assumed that the user goes out and the remote operation device is taken out of the building, and the invalidation of the remote unlocking operation is released. .. For this reason, it is possible to maintain the invalid state while the remote operation device is brought into the building and cancel the invalidation when the remote operation device is taken out of the building. Thereby, it becomes possible to allow the remote unlocking operation when the user enters the building while suppressing the unexpected unlocking by the remote operation indoors.

In a sixth aspect of the present invention, the releasing means, when the unlocking operation unit is operated to unlock the locking device and the remote operation device moves out of a communication range with the receiving device, The invalidation of the remote unlocking operation performed by the invalidating means is released.

In a seventh invention, a plurality of the remote operation devices are provided, each of the remote operation devices is provided with a storage unit that stores unique identification information, and the reception device is provided near the doorway. Is configured to be able to receive the identification information transmitted from each of the remote operation devices, and the control means is within a communication range with the receiving device based on the identification information received by the receiving device. Is provided with specifying means for specifying which of the plurality of remote controlling devices the remote controlling device is located at, and the releasing means is the remote controller of the remote controlling device specified by the specifying means. It is characterized by canceling the invalidation of the unlocking operation.

According to the seventh aspect of the present invention, when a plurality of remote control devices are used, it is possible to cancel the invalidation of the remote unlocking operation targeting the remote control device approaching the doorway. This makes it possible to avoid invalidating not only the remote operation device of the outing person but also the remote operation device of the in-home person when the user leaves the home and leaves.

When the seventh invention is applied to the sixth invention, the configuration relating to the “release means” is defined as “the unlocking device is unlocked by operating the unlocking operation section and is identified by the identifying means”. In addition, when the remote operation device moves out of the communication range with the receiving device, the invalidation of the remote unlocking operation of the specified remote operation device is released."

According to this configuration, when a plurality of remote control devices are used, it is possible to identify the remote control device taken out of the building and cancel the invalidation. As a result, when a user carries his or her own remote operation device and goes out while another remote operation device is placed within the communication range, only the remote operation device that is brought out of the building accompanying the user Not only that, it is possible to avoid canceling the invalidation of other remote control devices that are still in the communication range.

In an eighth aspect of the present invention, there is provided direction detecting means for detecting a moving direction of a person with respect to the entrance/exit in the building, and the releasing means is unlocked by the locking device based on an operation of the unlocking operation part. It is characterized in that the direction detecting means is provided with means for not canceling the invalidation of the remote unlocking operation when the movement of the person in the direction away from the doorway is detected.

In the eighth invention, even if the locking device is unlocked by the unlocking operation unit, if the movement of the person in the direction away from the doorway (movement moving toward the inside of the building) is detected, the remote Invalidation of unlock operation is not released. Accordingly, when the user does not go out only after unlocking the locking device (when the remote operation device is not brought out of the building), the invalidation of the remote unlocking operation can be maintained. Therefore, for example, it is possible to avoid the cancellation of invalidation due to manual unlocking from inside the building at the time of receiving home delivery or visiting a visitor.

In a ninth aspect, the control means is configured to allow a remote locking operation based on the operation signal even when the remote unlocking operation is disabled by the disabling means. And

According to the ninth aspect, the remote locking operation can be performed even when the remote unlocking operation is disabled. Therefore, it is possible to perform the remote locking operation both indoors and outdoors while suppressing the unexpected unlocking due to the remote operation indoors, which improves convenience.

<First Embodiment>
An embodiment of the locking/unlocking system of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram schematically showing a floor plan layout of a first floor portion of a building.

As shown in FIG. 1, a building (house) 10 is provided with an entrance 11 as main building spaces and rooms 12, 13, 14, and 15 including living rooms and kitchens. An entrance 21 is provided in the entrance 11, and an entrance door 22 is provided in the entrance 21.

FIG. 2 is a schematic diagram showing a configuration relating to locking/unlocking control in the entrance door 22. As shown in the figure, the entrance door 22 is provided with a locking device 23 including an electric cylinder lock. In the locking device 23, the cylinder portion 24 is provided so as to be exposed at the front surface (outdoor surface) of the entrance door 22, and the thumb turn portion 25 is provided so as to be exposed at the rear surface (indoor surface) of the entrance door 22. ..

The locking device 23 is operated by pointing the key part 42 of the electronic key 41 into the cylinder part 24 and rotating it, or by rotating the knob of the thumb turn part 25, so that the lock bar (shown in the figure) mounted on the locking device 23. Is omitted, and the entrance door 22 is in a locked or unlocked state. The locking device 23 includes an electrically driven actuator (not shown), and the lock bar can be retracted and retracted by driving the actuator. When the lock bar is in the protruding state, the front door 22 is in the locked state, and when the lock bar is in the retracted state, the front door 22 is in the unlocked state.

Further, the lock device 23 has a lock/unlock sensor 26 for detecting whether the state of the lock device 23 is locked or unlocked, and whether or not a manual unlock operation by the operation of the thumb turn portion 25 is performed. And a manual unlocking sensor 27 for detecting The manual unlocking sensor 27 can be configured by, for example, a touch sensor or the like that detects contact with the knob of the thumb turn portion 25.

In this system, the locking device 23 can be locked and unlocked by remote operation from an electronic key 41 carried by a resident or the like (user U in the figure). As a configuration for this, the communication device 31 and the controller 32 are provided. And are provided. The communication device 31 is provided near the entrance door 22 (or on the side surface of the entrance door 22). The communication area CA for wireless communication in the communication device 31 is a circular predetermined area centered on the communication device 31 (see FIG. 1) in plan view. Further, the controller 32 includes a microcomputer having a CPU, a memory and the like, and the locking device 23 and the communication device 31 are electrically connected to the controller 32. To the controller 32, the detection signals of the locking/unlocking sensor 26 and the manual unlocking sensor 27 are transmitted from the locking device 23, and the reception information from the electronic key 41 is transmitted via the communication device 31.

The electronic key 41 includes a memory (not shown) that stores unique ID information for each electronic key 41, and transmits the ID information in response to a request from the controller 32. Here, the communication device 31 transmits a request signal at a predetermined time cycle, whereas the electronic key 41 responds to the request signal when it enters the communication area CA with the communication device 31 and receives the request signal. Then, the ID information is transmitted to the communication device 31. Then, after the ID information is transmitted to the communication device 31, the controller 32 determines whether the ID information from the electronic key 41 and the pre-registered ID information match each other, and authenticates whether the key is a regular key. To do.

Further, the electronic key 41 is provided with an operation unit 44 for locking and unlocking the locking device 23 by remote operation. The operation unit 44 is provided with a locking switch 45 for locking and an unlocking switch 46 for unlocking. The electronic key 41 transmits an operation signal for locking or unlocking when the switches 45 and 46 are pressed.

Then, when the operation signal from the electronic key 41 is received by the communication device 31 in the situation where the electronic key 41 is properly authenticated by the ID information, the controller 32 locks and unlocks the locking device 23 based on the operation signal. To do. Specifically, it is determined whether to unlock or lock the locking device 23 based on the information received from the communication device 31, and when unlocking, an unlocking signal is output to the locking device 23 to lock it. In that case, a lock signal is output to the lock device 23. By the way, when the electronic key 41 does not correspond to the authorized one, the locking/unlocking of the locking device 23 is not performed.

As shown in FIG. 2, in the present system, the entrance 11 is provided with first and second human sensors 51 and 52. The first human presence sensor 51 is provided at a position inside the building 10 from the entrance 21, and is configured to detect the presence of a person near the entrance 21. As shown in FIG. 1, while the communication device 31 sets the inside and outside of the building 10 as the communication area CA, the first human presence sensor 51 positions and detects the inside of the building 10 as the detection area DA1. The range is set. Therefore, when the user enters the building 10 through the entrance 21, the user enters the detection area DA1 after entering the communication area CA. Here, the detection area DA1 is smaller than the communication area CA, and is set to fit within the communication area CA.

The second motion sensor 52 is provided at a position more inside the building 10 than the first motion sensor 51, and is for detecting the moving direction of a person at the entrance 11. As shown in FIG. 1, the second human sensor 52 has an arrangement position and a detection range set so that the detection area DA2 of the second human sensor 52 does not overlap the detection area DA1 of the first human sensor 51. Has been done. Further, the detection area DA2 is set such that a part of the entrance area 21 side thereof overlaps with the communication area CA. Therefore, when the user in the detection area DA1 moves toward the inner side of the building 10, after exiting the detection area DA1, it enters the detection area DA2 before leaving the communication area CA. ..

Note that, in FIG. 2, the first and second human sensor 51, 52 are arranged on the ceiling portion (ceiling surface) of the entrance 11, but the position of the human sensor 51, 52 is limited to the ceiling portion. It is not something that will be done. It is sufficient if the detection areas DA1 and DA2 can be set as described above. For example, the presence sensors 51 and 52 are arranged on the side wall portion (side surface) or the floor portion (floor surface) of the entrance 11. It may be.

The first and second motion sensors 51 and 52 are electrically connected to the controller 32, and the detection signals of the motion sensors 51 and 52 are output to the controller 32. The controller 32 controls invalidation and cancellation of the remote unlocking operation by the electronic key 41 based on the detection signals of the sensors 26, 27, 51, 52.

Next, the flow of the locking/unlocking control of the locking device 23 by the controller 32 will be described based on the flowcharts of FIGS. This control process is executed by the controller 32 in a predetermined time cycle.

In FIG. 3, in step S101, it is determined whether or not the authentication flag is on. The authentication flag indicates that the communication device 31 receives the ID information from the electronic key 41, in other words, the electronic key 41 is located in the communication area CA. When a negative determination is made in step S101, it is determined in step S102 whether the communication device 31 has received the ID information from the electronic key 41. If the ID information has not been received, the locking/unlocking control process ends.

On the other hand, if an affirmative decision is made in step S102, then in step S103 the received ID information is compared with the previously registered ID information, and authentication is performed as to whether or not the key is a legitimate key. Further, in step S103, the electronic key 41 is specified based on the ID information received by the communication device 31. That is, in this step, when a plurality of electronic keys 41 having different ID information are used, it is specified which of the plurality of electronic keys 41 has entered the communication area CA.

Next, in step S104, the authentication flag is turned on, and in the subsequent step S105, remote locking/unlocking processing is executed. This remote locking/unlocking process is for locking/unlocking the locking device 23 based on the switch operation of the electronic key 41.

In the remote locking/unlocking process, as shown in FIG. 4, first, in step S201, it is determined whether or not the remote locking operation is performed. That is, it is determined whether or not the operation signal for locking is received from the electronic key 41. When the operation signal for locking is received, the locking signal is output and the locking device 23 is locked in step S202, and the remote locking/unlocking process ends.

On the other hand, when a negative determination is made in step S201, it is determined in step S203 whether a remote unlocking operation has been performed. That is, it is determined whether or not an operation signal for unlocking is received from the electronic key 41. When a negative determination is made in step S203, that is, when neither the remote locking operation nor the remote unlocking operation has been performed, the remote locking/unlocking process ends.

On the other hand, if an affirmative decision is made in step S203, it is decided in step S204 whether or not the prohibition flag is in the on state. This prohibition flag indicates that the remote unlocking operation using the electronic key 41 is in a prohibited state (invalid state). In this step, the electronic key 41 specified by the process of step S103 of FIG. 3 is targeted, and it is determined whether or not the prohibition flag for the electronic key 41 is in the ON state. The prohibition flag setting process and the set prohibition flag releasing process will be described later.

When a negative determination is made in step S204, an unlock signal is output in step S205 to unlock the locking device 23, and the remote locking/unlocking process ends. On the other hand, if an affirmative decision is made in step S204, the processing of step S205 is skipped and the remote locking/unlocking processing ends. That is, when the prohibition flag is ON, the locking device 23 is not unlocked even if the remote unlocking operation is performed.

Returning to the description of FIG. 3, if an affirmative determination is made in step S101, it is determined in step S106 whether reception of ID information has been turned off. That is, it is determined whether or not the response state in which the electronic key 41 responds to the request signal from the communication device 31 shifts to the non-response state in which there is no response. As a result, it is determined whether the electronic key 41 located inside the communication area CA has moved outside the communication area CA. When a negative determination is made in step S106 (when the electronic key 41 is located within the communication area CA), the remote locking/unlocking process of step S105 is executed. On the other hand, when an affirmative determination is made in step S106 (when the electronic key 41 has come out of the communication area CA), the authentication flag is turned off in step S107.

After execution of step S105 or step S107, it is determined in step S108 whether the prohibition flag for the specified electronic key 41 is in the ON state. When a negative determination is made in step S108, invalidation processing is executed in step S109. This invalidation processing is for invalidating the remote unlocking operation of the electronic key 41, in other words, processing for setting the prohibition flag to the ON state.

In the invalidation process, as shown in FIG. 5, first, in step S301, it is determined whether the timer flag is in the ON state. When a negative determination is made in step S301, it is determined in step S302 based on the detection signal of the locking/unlocking sensor 26 whether the locking device 23 has been unlocked. The unlocking in this step assumes outdoor operation. In this step, the case where the electronic key 41 is unlocked by pointing the electronic key 41 into the cylinder 24, and the case where the electronic key 41 is remotely unlocked by the switch operation of the electronic key 41 are also targeted.

When a negative determination is made in step S302, the invalidation processing ends. On the other hand, if an affirmative decision is made in step S302, the monitoring time T is set in the timer in step S303. The monitoring time T is for measuring and monitoring the elapsed time from the unlocking of the locking device 23 to the detection of a person by the first motion sensor 51. In other words, the unlocking operation is performed outside the building 10. This is to monitor the elapsed time from the time when the event is performed until a person enters the entrance 11. Since the unlocking operation may be performed at a position away from the locking device 23 by operating the switch of the electronic key 41, the monitoring time T is set to, for example, 10 seconds in consideration of the moving time.

In the following step S304, the timer flag is turned on. This timer flag indicates that the elapsed time is being measured and monitored. After the execution of step S304 or when the affirmative judgment is made in step S301, it is judged in step S305 whether or not the monitoring time T set by the timer has elapsed. When the monitoring time T has not elapsed, it is determined in step S306 whether the presence of a person is detected by the first motion sensor 51 based on the detection signal of the first motion sensor 51.

If an affirmative decision is made in step S306, the prohibition flag is set to the ON state in the subsequent step S307, and the remote unlocking operation by the electronic key 41 is invalidated. Then, in step S308, the timer flag is turned off, the monitoring of the elapsed time is terminated, and the invalidation processing is terminated.

On the other hand, if a negative determination is made in step S306, the invalidation processing ends. In this case, the determination process of step S306 is re-executed at the next execution timing of the locking/unlocking control process (FIG. 3), and thereafter, the same process is repeated until the monitoring time T elapses. Then, if an affirmative decision is made in step S305, that is, if the monitoring time T has elapsed without the presence of a person being detected by the first human sensor 51, the operation proceeds to step S308 and the prohibition flag is not turned on. Turn off the timer flag.

Returning to the description of FIG. 3, if an affirmative determination is made in step S108, the cancellation process is executed in step S110. This cancellation processing is for canceling the invalidation of the remote unlocking operation.

In the release processing, as shown in FIG. 6, first, in step S401, it is determined whether or not the manual unlock flag is on. When a negative determination is made in step S401, it is determined in step S402 based on the detection signal of the manual unlock sensor 27 whether or not the unlock operation by the operation of the thumb turn portion 25 has been performed.

When a negative determination is made in step S402, the canceling process ends. On the other hand, if an affirmative decision is made in step S402, the manual unlock flag is turned on in step S403. This manual unlocking flag indicates that the unlocking operation by the operation of the thumb turn portion 25 has been performed, in other words, the locking device 23 has been unlocked by the manual operation from inside the building 10.

If an affirmative decision is made in step S401, or after the execution of step S403, then in step S404, based on the detection signal of the second motion sensor 52, the presence of a person is detected by the second motion sensor 52. Determine whether. When a negative determination is made in step S404, it is determined in step S405 whether the authentication flag is off.

If an affirmative decision is made in step S405, the prohibition flag is turned off and the invalidation of the remote unlocking operation is canceled in step S406. That is, after the manual unlocking operation is performed, if the electronic key 41 goes out of the communication area CA without the person being detected by the second motion sensor 52, the person goes out and the electronic key 41 goes out of the building 10. Assuming that it has been taken out, the remote unlocking operation is canceled. After that, in step S407, the manual unlock flag is turned off, and the release process ends.

On the other hand, if an affirmative decision is made in step S404, the operation proceeds to step S407, and the manual unlocking flag is turned off while maintaining the invalidation of the remote unlocking operation. That is, when a person is detected by the second motion sensor 52 before the electronic key 41 exits the communication area CA, the person returns to the back of the building 10 after the manual unlocking operation, and the electronic key 41 moves outside the building 10. It will be considered as not taken out and will remain invalid.

In addition, when a negative determination is made in step S405, that is, when neither the detection of the person by the second human sensor 52 nor the movement of the electronic key 41 to the outside of the communication area CA has occurred, the releasing process is ended. In this case, the determination process of steps S404 and S405 is re-executed at the next execution timing of the locking/unlocking control process (FIG. 3), and thereafter, both processes are repeated until a positive determination is made in any of the determination processes.

Next, the operation when the user carrying the electronic key 41 enters the building 10 will be described with reference to FIG. 7. Here, as shown in FIG. 7B, the user UA carrying the electronic key 41A returns home, and then, as shown in FIG. 7C, the electronic key 41B having different ID information from the electronic key 41A is displayed. A case where the user UB carrying the mobile phone returns home will be described as an example.

As shown in FIG. 7A, when the electronic key 41A enters the communication area CA at the timing t1, the electronic key 41A is identified based on the ID information, and the authentication flag for the electronic key 41A is turned on. .. At the subsequent timing t2, when the user UA performs a remote unlocking operation with the electronic key 41A, the locking device 23 is unlocked.

Then, at timing t3, when the user UA enters the building 10 and enters the detection area DA1 of the first motion sensor 51, the detection signal of the first motion sensor 51 is turned on. Along with this, the prohibition flag A for the electronic key 41A is turned on, and the remote unlocking operation of the electronic key 41A is invalidated. Then, at the timing t4, when the user UA performs the locking operation by the electronic key 41A or manually, the locking device 23 is locked.

When the user UA keeps the electronic key 41A in the communication area CA and the unlock switch 46 of the electronic key 41A is operated in that state (timing t5), the remote unlocking operation is invalidated. Therefore, the locking device 23 is not unlocked. Therefore, the unexpected unlocking by the remote unlocking operation in the building 10 is suppressed.

After that, at timing t6, when the user UB returns home and the electronic key 41B enters the communication area CA, the electronic key 41B is identified, and the authentication flag for the electronic key 41B is turned on. When the user UB performs the remote unlocking operation with the electronic key 41B at the subsequent timing t7, the lock device 23 is unlocked because the prohibition flag is set only for the electronic key 41A. In this way, since the remote unlocking operation is invalidated for each of the electronic keys 41A and 41B, it is possible to prevent the remote unlocking operation of the electronic key 41B from being disturbed by the invalidation setting for the electronic key 41A.

Next, the operation when the user carrying the electronic key 41 leaves the building 10 will be described with reference to FIG. Here, as shown in FIGS. 8B and 8C, a case where the user UA carrying the electronic key 41A goes out with the electronic key 41B placed in the communication area CA will be described as an example.

As shown in FIG. 8A, when the user UA unlocks the locking device 23 by operating the thumb turn portion 25 at the timing t11, the manual unlock flag is turned on. At this time, since both the electronic keys 41A and 41B are located in the communication area CA, the authentication flags of both the electronic keys 41A and 41B are in the ON state.

After that, when the user UA exits the entrance 21 and leaves the building 10 and the electronic key 41A moves outside the communication area CA (timing t12), the prohibition flag A for the electronic key 41A is turned off. At this time, since the electronic key 41B remains in the communication area CA, the prohibition flag B of the electronic key 41B is not turned off. For this reason, the remote unlocking operation is canceled only for the electronic key 41A, and the invalidation of the remote unlocking operation is maintained for the electronic key 41B.

Therefore, at the later timing t13, even if the remote unlocking operation is performed by the electronic key 41B, the locking device 23 is not unlocked. As described above, turning off the authentication flag (moving to the outside of the communication area CA) is one of the cancellation conditions, so that the electronic keys 41B that are only placed in the communication area CA may be excluded from the cancellation target. it can.

Since the remote unlocking operation of the electronic key 41A has been canceled, the locking device 23 can be unlocked by the remote unlocking operation when the user UA returns home (timing t14, t15).

Next, an operation when the locking device 23 is unlocked by a manual operation from indoors but the user is not outdoors will be described with reference to FIG. Here, as shown in FIGS. 9B and 9C, a case where the user UA carrying the electronic key 41A unlocks the locking device 23 and then returns to the room 15 will be described as an example. Note that this example is intended for receiving home delivery.

As shown in FIG. 9A, when the user UA moves from the room 15 in the building 10 toward the locking device 23 and the electronic key 41A enters the communication area CA at timing t21, the authentication flag of the electronic key 41A. Turns on. At the subsequent timing t22, when the user UA unlocks the locking device 23 by operating the thumb turn section 25, the manual unlock flag is turned on.

After the user UA opens the front door 22 to receive the package, closes the front door 22 and locks the locking device 23, and then returns to the room 15, at time t23, the electronic key 41A detects the second person. The detection area DA2 of the sensor 52 is entered. Along with this, the detection signal of the second motion sensor 52 is turned on. Further, along with this, the manual unlocking flag is turned off, and the release processing for canceling the invalidation of the remote unlocking operation ends (see steps S404 and 407 in FIG. 6).

In the case of FIG. 8 already described, the invalidation is released in response to the authentication flag of the electronic key 41A being turned off, but in this case, it is released in response to the detection signal of the second human sensor 52 being turned on. The process ends. Therefore, at a later timing t24, the invalidation is not canceled even if the authentication flag of the electronic key 41A is turned off. In this way, when the locking device 23 is only manually unlocked from the inside of the building 10 (when the electronic key 41A is not carried out outdoors), the invalidation of the remote unlocking operation is maintained. Therefore, even at the subsequent timing t25, the locking device 23 is not unlocked even if the electronic key 41A is remotely unlocked.

According to this embodiment described in detail above, the following excellent effects are recognized.

The remote unlocking operation of the electronic key 41 is invalidated when the presence of a person is detected by the first motion sensor 51 after the locking device 23 is unlocked. When the user enters the building 10, it is necessary to unlock the locking device 23 and then pass through the entrance 21, and when the detection by the first motion sensor 51 is made subsequent to the unlocking of the locking device 23. It is assumed that the user has entered the building 10 and the electronic key 41 has been brought into the building 10. Then, triggered by this, the remote unlocking operation by the electronic key 41 is invalidated.

Therefore, the remote unlocking operation can be invalidated after properly grasping the carry-in of the electronic key 41 into the building 10. As a result, after the electronic key 41 is brought into the building 10, unlocking by operating the electronic key 41 does not function. Therefore, it is possible to prevent the locking device 23 from being unlocked abruptly by the remote operation performed in the building 10 without affecting the outdoor use before bringing the building 10 into the building 10 and to improve the convenience. It will be possible.

The remote unlocking operation of the electronic key 41 is invalidated when the elapsed time from the unlocking of the locking device 23 to the detection of the person by the first motion sensor 51 is within the monitoring time T. Therefore, when there is a high possibility that the person who unlocks the locking device 23 and the person who enters the building 10 are the same person, in other words, the unlocking operation of the locking device 23 and the entry into the building 10 are performed. If there is a high possibility that the above steps have been performed as a series of operations and there is a high possibility that the electronic key 41 has been brought into the building 10, the remote unlocking operation can be invalidated. As a result, it becomes possible to perform the invalidation process after more appropriately grasping the carry-in of the electronic key 41 into the building 10.

When a plurality of electronic keys 41A and 41B are used, the electronic keys 41A and 41B are identified based on the ID information, and the remote unlocking operation is invalidated for each key. As a result, the remote unlocking operation is invalidated by the user UA who first enters the building 10 when the access timings to the building 10 are mixed between the plurality of users UA and UB, and as a result, the user UB who later enters the building 10 It is possible to preferably eliminate the inconvenience that the remote unlocking is impossible.

After the unlocking of the locking device 23 by the manual operation from inside the building 10, when the electronic key 41 moves to the outside of the communication area CA, the invalidation of the remote unlocking operation is released. When the user goes out, after unlocking the locking device 23 from the inside, the flow goes out of the entrance 21 and away from the building 10. In the communication area of the electronic key 41 following the manual unlocking operation from the inside. When the movement to the outside of the CA is confirmed, it is considered that the electronic key 41 has been taken out of the building 10. Then, triggered by this, the invalidation of the remote unlocking operation is released.

Therefore, it is possible to cancel the invalidation of the remote unlocking operation after properly grasping the carry-out of the electronic key 41 outside the building 10. Thus, while the electronic key 41 is brought into the building 10, the invalid state can be maintained, and the invalid state can be released when the electronic key 41 is brought out of the building 10. Therefore, it is possible to allow the remote unlocking operation when the user comes home or the like while suppressing the unexpected unlocking by the remote operation in the building 10.

After unlocking the locking device 23 from inside the building 10, the electronic key 41 is taken out of the building 10 by waiting for the movement of the electronic key 41 outside the communication area CA and canceling the invalidation. Only when it is released, the invalidation of the remote unlocking operation can be released. As a result, it is possible to prevent the invalidation of other electronic keys 41 that are only placed in the communication area CA.

When a plurality of electronic keys 41A and 41B are used, the electronic keys 41A and 41B are identified based on the ID information, and the invalid state of the remote unlocking operation is released for each key. This makes it possible to avoid invalidating not only the electronic key 41 of a person who has gone out but also the electronic key 41 of a person who is at home when leaving the home.

When the presence of a person is detected by the second motion sensor 52 after manually unlocking the locking device 23, the invalidation of the remote unlocking operation is not released. That is, when a person enters the detection area DA2 of the second motion sensor 52 following the manual unlocking of the locking device 23, it is considered that the person has returned to the building 10 after unlocking the locking device 23. , Leave the remote unlocking operation disabled. As a result, it becomes possible to more appropriately grasp the take-out of the electronic key 41 outside the building 10, and it is invalid due to, for example, manual unlocking from the inside of the building 10 at the time of receiving a home delivery or when a visitor comes. It is possible to avoid being released.

-The target of invalidation is limited to the remote unlocking operation, and the remote unlocking operation is allowed even when the remote unlocking operation is disabled. As a result, it is possible to perform the remote locking operation both indoors and outdoors while suppressing the unexpected unlocking by the remote operation indoors, which improves convenience.

<Second Embodiment>
In this embodiment, the disabling process of the remote unlocking operation is different from that in the first embodiment. In the present embodiment, the first motion sensor 51 is not provided, and the motion sensor includes only the second motion sensor 52. The invalidation process of this embodiment can be performed instead of the invalidation process of the first embodiment shown in FIG.

FIG. 10 is a flowchart showing the invalidation processing in this embodiment. Note that the same step numbers are given to the same processing as the invalidation processing (FIG. 5) of the first embodiment, and description thereof will be omitted.

As shown in FIG. 10, when a negative determination is made in the determination processing of step S305 (determination processing of whether or not the monitoring time T set by the timer has elapsed), the locking device is operated by operation from inside the building 10 in step S501. It is determined whether or not 23 is locked. This step is applicable not only to the case where the thumb turn section 25 is operated and locked but also to the case where the thumb key is remotely locked by the switch operation of the electronic key 41.

Here, when remote locking is performed, there is no direct means for identifying whether the remote locking is performed by remote control indoors or remotely. However, when a person enters from the outside of the building 10 through the entrance 21, the unlocking device 23 is unlocked outside the building 10 and then enters the building 10 before locking. Based on this point, if the remote locking is performed following the unlocking operation (unlocking operation from the outdoors) when the prohibition flag is not set (see step S108 in FIG. 3 and step S302 in FIG. 10), It is regarded as a lock operation performed in the building 10.

If an affirmative decision is made in step S501, then in the subsequent step S307, the prohibition flag is turned on and the remote unlocking operation by the electronic key 41 is invalidated. Then, in step S308, the timer flag is turned off, the monitoring of the elapsed time is terminated, and the invalidation processing is terminated.

On the other hand, if a negative determination is made in step S501, the invalidation processing ends. In this case, the determination process of step S501 is re-executed at the next execution timing of the locking/unlocking control process (FIG. 3), and thereafter, the same process is repeated until the monitoring time T elapses. Then, when the monitoring time T has elapsed without performing the locking operation from inside the building 10, the process proceeds to step S308, and the timer flag is turned off without turning the prohibition flag on.

As described above, in the present embodiment, when the locking operation is performed from the inside of the building 10 after unlocking the locking device 23, it is assumed that the electronic key 41 is brought into the building 10 and the remote unlocking operation of the electronic key 41 is performed. Configured to disable. As a result, it is possible to achieve the same effect as that of the first embodiment.

<Other embodiments>
(1) In the first embodiment, the remote unlocking operation is invalidated when the presence of a person is detected by the first motion sensor 51 after unlocking the locking device 23. Instead of “after locking”, “after opening the front door 22” may be used. In this case, an opening/closing sensor for detecting opening/closing of the entrance door 22 may be provided in the entrance door 22 or the entrance 21, and it may be determined whether or not the entrance door 22 is opened based on a detection signal of the opening/closing sensor. This also applies to the second embodiment, and the remote unlocking operation may be invalidated when the locking operation is performed from inside the building 10 after the entrance door 22 is opened.

(2) In each of the above-described embodiments, when the elapsed time from the unlocking of the locking device 23 to the person detection by the first motion sensor 51 is within the monitoring time T, the remote unlocking operation of the electronic key 41 is invalidated. However, instead of or in addition to this, when the presence of a person is detected by the first motion sensor 51 between the time when the locking device 23 is unlocked and the time when it is locked, the remote unlocking operation is invalidated. May be turned into. With this configuration, the remote unlocking operation can be invalidated when the person who unlocks the locking device 23 and the person who has entered the building 10 are highly likely to be the same person. If both the configuration in which the elapsed time is within the monitoring time T is the invalidation condition and the configuration in which the person detection is performed before locking is the invalidation condition, both conditions are satisfied. In this case, the remote unlocking operation may be invalidated.

(3) In each of the above-described embodiments, the electronic key 41 is automatically authenticated when the electronic key 41 is located in the communication area CA. However, the ID is generated when the unlock switch 46 or the lock switch 45 is operated. Information may be transmitted to the communication device 31.

(4) In each of the above embodiments, the individual unlocking of the electronic key 41 is performed, and then the remote unlocking operation is invalidated and released. However, such authentication is not performed, or is independent of the authentication result. It may be configured to invalidate or cancel it. For example, when it is expected that the number of electronic keys 41 used is one, such as in a single-person household, the above configuration can also appropriately prevent an unexpected unlocking in the building 10. The same effect as each embodiment can be expected.

(5) In each of the above-described embodiments, in the determination process of step S302 (determination process of whether or not the unlocking operation is performed from outside the building 10), the unlocking operation by the cylinder unit 24 is performed as the unlocking operation from outside the building 10. Although both the operation and the remote unlocking operation by the electronic key 41 are targeted, only the remote unlocking operation may be targeted. According to this configuration, it is possible to preferably cope with a case where a mechanical spare key having no remote control function is provided in addition to the electronic key 41. That is, in an environment where the electronic key 41 and the mechanical key coexist, it is possible to prevent the remote unlocking operation of the electronic key 41 from being invalidated by bringing in the mechanical key. In this case, the electronic key 41 may not be provided with the key portion 42 in order to favorably distinguish between the unlocking operation using the electronic key 41 and the unlocking operation using the mechanical key.

(6) In each of the above embodiments, the remote unlocking operation is invalidated when the electronic key 41 moves out of the communication area CA after unlocking the locking device 23 by manual operation from inside the building 10. It may be configured such that the movement of the key 41 out of the communication area CA is not a condition for canceling the invalidation. In this case, the invalidation may be promptly released in response to the manual unlocking of the locking device 23. As a result, it is possible to improve the responsiveness of canceling the invalidation of the electronic key 41 taken out.

(7) In each of the above embodiments, the electronic key 41 integrally includes the key portion 42 and the operation portion 44, but the operation portion 44 may be provided separately from the key portion 42. In this case, it is preferable that the operation unit 44 is composed of a small-sized portable device so that it can be carried easily without being disturbed. For example, a bracelet type portable device with a wristband attached to the portable device body, a pendant type portable device with a neck chain attached to the portable device body, and a badge with a spring hook or badge pin attached to the portable device body. It can be considered to be embodied as a portable device. In addition, a mobile phone that is used on a daily basis may be usable as the operation unit 44. When the operation unit 44 and the key unit 42 are separately configured, it is preferable that the operation unit 44 has a function of transmitting ID information.

(8) In each of the above-described embodiments, the present locking and unlocking system is applied to the entrance 21 of the building 10, but it is also possible to apply the present unlocking system to other entrances and exits such as an arbitrary entrance and a window. In this case, it may be applied to another entrance/exit in place of the entrance 21, or may be applied to another entrance/exit in addition to the entrance 21.

(9) In each of the above-described embodiments, the second motion sensor 52 is used as the “direction detecting means”, but the camera captures an image of the entrance 11 (a predetermined area entering the building 10 from the entrance 21), and The moving direction of the person may be detected based on the captured image.

(10) In the second embodiment, in the determination process of step S501 (determination process of whether or not the lock is performed by the operation from inside the building 10), the remote lock operation by the electronic key 41 is performed as the lock operation from inside the building 10. Although both the manual lock operation by the thumb turn section 25 and the manual lock operation by the thumb turn section 25 are targeted, only the manual lock operation may be targeted. In this case, although the electronic key 41 may be partially missed, it is possible to accurately determine whether or not the electronic key 41 has been locked by an operation from inside the building 10, and the remote unlocking can be performed without the electronic key 41 being brought in. It is possible to suppress a malfunction that invalidates an operation.
