Description

The present invention relates to a building locking/unlocking system.

2. Description of the Related Art In buildings such as houses, a locking/unlocking system that locks/unlocks a locking device provided on a door using an electronic key having a wireless function has been put to practical use. In recent years, some locking/unlocking systems are provided with an alert mode. The alert mode is set, for example, when the electronic key is used to lock the door when the user goes out, and is released when the electronic key is used to unlock the door when the user returns home. Then, when the door is opened by means other than the electronic key while the alert mode is set, it is determined that the door is in an abnormal state, and warning processing such as issuing an alarm is executed.

If the electronic key is used to unlock the door while the security mode is set, the security mode is canceled as well as the lock is unlocked. For the user who has the electronic key, the security mode is a system that combines crime prevention and convenience. . On the other hand, if the door cannot be unlocked with the electronic key for some reason (for example, the battery of the electronic key is dead), the user may manually unlock the locking device using the mechanical key from the outside to open the door. In this case, even though the door has been opened by a legal method, the electronic key has not been used to unlock the door.

Therefore, when the door is manually unlocked from the outside using the mechanical key, there has been proposed a method of canceling the alert mode based on a predetermined operation of the locking device with the mechanical key. For example, Patent Literature 1 discloses that the inserted mechanical key is rotated from the locked position to the unlocked position and from the unlocked position to the locked position within a predetermined time after the mechanical key is inserted into the key cylinder of the locking device. It is disclosed that the alert mode is canceled by operating the

By the way, in the locking/unlocking system using the electronic key, locking/unlocking is mainly performed by the electronic key, and it is assumed that the opportunity to unlock the locking device by the mechanical key (that is, the opportunity to release the security mode by the mechanical key) is not frequent. be done. Therefore, for example, in the technique of Document 1, there is a possibility that the operation cannot be performed within a predetermined time because the unfamiliar operation is forced to cancel the alert mode, and in this case, the warning process is executed. .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a building locking/unlocking system capable of ensuring crime prevention and improving convenience for users.

In order to solve the above problems, the building locking/unlocking system of the first invention includes:
A building locking/unlocking system for locking an opening/closing member provided at an entrance of a building,
a locking device that enables electrical locking/unlocking using an electronic key and mechanical locking/unlocking using a mechanical key;
Mode switching means for setting an alert mode when the electronic key is used for locking, and canceling the alert mode when the electronic key is used for unlocking;
a first warning means for issuing a warning when the opening/closing body is opened without being unlocked by the electronic key under the caution mode setting state;
The warning is provided on the condition that a predetermined first operation is performed using the mechanical key while the alert mode is set, and a predetermined second operation is performed using the mechanical key within a predetermined time limit from the first operation. mode release means for releasing the mode;

time extension means for extending the time limit when a predetermined time extension operation is performed before the time limit elapses from the first operation;
characterized by comprising

According to the first invention, two operations (first operation and second operation) using the mechanical key must be performed within a time limit in order to cancel the alert mode without unlocking with the electronic key (hereinafter referred to as manual operation). It is required and this ensures security. Further, according to the first invention, when the first operation and the second operation necessary for manually canceling the alert mode cannot be performed within the time limit, the time limit is extended by performing the extension operation. be. As a result, when the user is not accustomed to manually canceling the alert mode, the time limit can be extended, and the time for performing the second operation can be secured. Also, by making it possible to extend the time limit, it is possible to shorten the time initially set as the time limit. For example, since the time limit for canceling the alert mode is short for an unauthorized person who attempts unauthorized access (an unauthorized person who does not know the extension function), security can be ensured even in a configuration that allows extension. Therefore, according to the first invention, it is possible to ensure security and improve convenience for the user.

The building locking/unlocking system of the second invention is, in the first invention,
The locking device includes a first locking device and a second locking device,

The second operation is at least one of unlocking and locking of the second locking device using the mechanical key.

According to the second invention, two locking devices are provided, the first operation is the locking/unlocking operation of the first locking device, and the second operation is the locking/unlocking operation of the second locking device. Therefore, the security mode is released by locking and unlocking the two locking devices with the mechanical key. As a result, when a user who does not have an electronic key uses the mechanical key to unlock the first locking device and the second locking device in order to enter the building, the warning mode is manually released. be able to. That is, when two locking devices are provided, the alert mode is canceled by unlocking the two locking devices by a legal method other than unlocking with the electronic key (that is, unlocking operation with the mechanical key). . Therefore, there is no need to perform an operation to cancel the alert mode, and convenience for the user can be improved.

A building locking/unlocking system of the third invention is, in the first and second inventions,
The time extension means extends the time limit by a predetermined amount of time based on the fact that the time extension operation has been performed. It is characterized by comprising extension prohibiting means for prohibiting extension of the time limit when an operation is performed.

According to the third invention, the extension of the time limit is prohibited after extending the time limit a predetermined number of times. That is, the number of extensions of the time limit is limited. As a result, it is possible to prevent the time limit from being infinitely extended, thereby ensuring security.

A locking and unlocking system for buildings according to a fourth invention, in any one of the first to third inventions,
An operation means is provided on the outdoor side near the entrance,
The time extension operation is an operation on the operation means different from the first operation and the second operation performed by the mechanical key.

According to the fourth invention, the operation means for performing the time extension operation is provided separately from the portion for performing the first operation and the second operation. As a result, when an unauthorized person tries to cancel the alert mode (unlock the locking device) by performing the first operation and the second operation with the mechanical key, it is possible to avoid accidentally performing the time extension operation. Crime prevention can be improved.

A building locking/unlocking system according to the fifth invention is, in the fourth invention,
The electrical locking/unlocking by the electronic key is configured such that the locking device is locked/unlocked when a predetermined permission operation is performed in a state where the identification information transmitted from the electronic key is authenticated,
The operation means operated for the permission operation is the operation means operated for the time extension operation.

According to the fifth invention, the operation means operated for the time extension operation and the operation means operated for the permission operation by the user in locking/unlocking by the electronic key are shared. Therefore, the operation means used for locking/unlocking with the electronic key can be used as the operation means operated for the time extension operation. This makes it possible to extend the time limit without requiring new equipment.

A locking/unlocking system for buildings according to a sixth invention, in any one of the first to fifth inventions,
It is characterized by comprising change means for changing the mode of the time extension operation.

For the user, it is desirable that the time extension operation be simple, but there is a concern that such a simple operation may reduce security. Moreover, if the user is observed to be performing the time extension operation, there is a concern that an unauthorized person may recognize the time extension operation. According to the sixth invention, for example, the time extension operation can be changed every day. This makes it difficult for an unauthorized person to recognize the time extension operation, and as a result, it is possible to improve crime prevention.

An embodiment embodying the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a locking/unlocking system for an entrance door. 2 is an enlarged view of a door handle portion provided on the entrance door of FIG. 1. FIG.

As shown in FIG. 1, a house 10 is provided with an entrance 15 as an entrance. It is possible to enter and exit the house 10 through the entrance 15 . Further, the entrance door 15 is provided with an entrance door 16 as an opening/closing body. The front door 16 is, for example, a swingable hinged door. An entrance 15 is opened and closed by this entrance door 16 .

A locking device 21 and a locking device 22 are attached to the entrance door 16 so as to be aligned vertically. The locking devices 21 and 22 are electric locks that lock and unlock when energized. The locking devices 21 and 22 can be locked/unlocked by an electronic key 31 carried by the resident of the house 10 .

The locking devices 21 and 22 have cylinder portions 21a and 22a (see FIG. 2). The locking devices 21 and 22 can be locked and unlocked by a predetermined operation of the cylinder portions 21a and 22a by the mechanical key 32. As shown in FIG. That is, after inserting the mechanical key 32 into the cylinder portions 21a and 22a, the locking devices 21 and 22 are unlocked by rotating the mechanical key 32 to the unlocking position, and the locking device is opened by rotating the mechanical key 32 to the locking position. 21 and 22 are locked. Therefore, the locking devices 21 and 22 can be electrically locked/unlocked by the electronic key 31 (hereinafter, locked/unlocked by the electronic key 31) and mechanically locked/unlocked by the mechanical key 32 (hereinafter, locked/unlocked by the mechanical key 32). It has become. The locking devices 21 and 22 correspond to a locking device, a first locking device and a second locking device.

The entrance door 16 is provided with a door handle 17 as a handle on the outdoor side. Covers 17a and 17b are attached to the upper and lower portions of the door handle 17, and when the covers 17a and 17b are opened, cylinder portions 21a and 22a of the locking devices 21 and 22 are provided (see FIG. 2). ). That is, the cylinder portions 21a and 22a are provided so as to protrude from the front surface (surface on the outdoor side) of the entrance door 16 and be exposed under the covers 17a and 17b of the door handle 17. As shown in FIG.

A touch sensor 18 is provided on the door handle 17 . The touch sensor 18 is a capacitive sensor, and detects that a person touches the sensor portion.

The locking devices 21 and 22 are respectively provided with locking/unlocking sensors 26 and 27 for detecting whether the locking devices 21 and 22 are locked or unlocked. The entrance door 16 is provided with an opening/closing detection sensor 28 for detecting opening/closing of the entrance door 16 .

A speaker 29 is built in the door handle 17 . The speaker 29 warns a person near the entrance door 16 on the outdoor side by outputting (emitting) a warning sound. Note that the speaker 29 may be attached to the outer wall of the house 10, for example.

A communication device 23 is provided on the outdoor side near the entrance door 16 (or on the outdoor side of the entrance door 16). A communication area CA for wireless communication in the communication device 23 is a predetermined spherical range centered on the communication device 23 . Specifically, the communication area CA of the communication device 23 is set so that when the resident grabs the door handle 17 on the outdoor side of the entrance door 16, the resident is positioned within the communication area CA.

Next, the electrical configuration of the locking/unlocking system will be described.

As shown in FIG. 1, the locking/unlocking system includes a controller 40 as control means. The controller 40 includes a well-known microcomputer consisting of CPU, ROM, RAM, etc., and is installed on the indoor side of the house 10 (for example, on the wall surface around the entrance). Note that the controller 40 may be provided inside the entrance door 16 .

The controller 40 includes a storage unit 41 that stores information for resident authentication (ID information of the electronic key 31) and detection results from various devices such as sensors, and a timer 42 that is used to measure time. I have.

Locking devices 21 and 22 and communication device 23 are connected to controller 40 . The communication device 23 can wirelessly communicate with the electronic key 31 carried by each resident living in the house 10 within the communication area CA. In this case, the controller 40 can wirelessly communicate with each resident's electronic key 31 via the communication device 23 .

The electronic key 31 has a memory (not shown) that stores unique ID information for each electronic key 31 , and transmits the ID information in response to a request from the controller 40 . Here, the communication device 23 transmits the request signal at a predetermined time period (for example, every 0.5 seconds), while the electronic key 31 enters the communication area CA, which is the communication area of the communication device 23. When receiving the request signal, it transmits the ID information to the communication device 23 in response to the request signal. Then, when the ID information is received by the communication device 23 , the ID information is input from the communication device 23 to the controller 40 . When the ID information from the electronic key 31 is input via the communication device 23 , the controller 40 determines whether the ID information matches the ID information registered in advance in the storage unit 41 . Authenticate whether or not there is.

A touch sensor 18 is connected to the controller 40 . The detection results are sequentially input to the controller 40 from the touch sensor 18 . Then, when the detection result from the touch sensor 18 (that is, the detection result indicating that a person has touched the touch sensor 18) is input in a situation where the electronic key 31 is officially authenticated by the ID information, the controller 40 The locking devices 21 and 22 are locked or unlocked (locked/unlocked by the electronic key 31). That is, when the detection result from the touch sensor 18 is input while the locking devices 21 and 22 are locked, the locking devices 21 and 22 are unlocked. When the detection result is input from the sensor 18, the locking devices 21 and 22 are locked. If the electronic key 31 is not authorized, the locking devices 21 and 22 are not locked or unlocked. Note that touching the touch sensor 18 corresponds to the permission operation.

Lock/unlock sensors 26 and 27 are connected to the controller 40 . Detection signals (locking detection signals or unlocking detection signals) of the locking/unlocking sensors 26 and 27 are input to the controller 40 . The locking/unlocking sensors 26 and 27 correspond to first detection means and second detection means.

An open/close detection sensor 28 is connected to the controller 40 . A detection signal (open detection signal or closed detection signal) of the open/close detection sensor 28 is input to the controller 40 .

A speaker 29 is connected to the controller 40 . The speaker 29 emits a warning sound for a predetermined period of time (for example, one minute) based on the warning sound transmission request from the controller 40 .

The locking/unlocking system of this embodiment is provided with an alert mode. The security mode is set and released by locking and unlocking with the electronic key 31 . For example, the alert mode is set based on the fact that the electronic key 31 is used to lock the door when the user goes out, and the alert mode is canceled when the electronic key 31 is used to unlock the door when the user comes home. Therefore, the controller 40 corresponds to mode switching means. It should be noted that even when the door handle 17 is locked by the electronic key 31, the locking is performed by the first touch operation of the door handle 17, and the alert mode is set by the second touch operation (i.e., the predetermined operation after locking). good.

When the front door 16 is opened without being unlocked by the electronic key 31 in the state where the alert mode is set (that is, when an open detection signal is input from the open/close detection sensor 28 to the controller 40 ), the controller 40 determines that there is an abnormality. In this case, the controller 40 executes warning processing. Specifically, the controller 40 transmits a warning sound transmission request to the speaker 29 . As a result, the speaker 29 emits a warning sound. Therefore, the controller 40 and the speaker 29 constitute the first warning means.

In this locking/unlocking system, a method for canceling the alert mode other than unlocking with the electronic key 31 is determined in a state in which the alert mode is set. Specifically, after the first operation (release of one of the locking devices 21 and 22 by the mechanical key 32) is performed, the second operation (release of the other of the locking devices 21 and 22 by the mechanical key 32) is performed within the time limit. is canceled), the alert mode is canceled. Hereinafter, releasing the security mode by means other than unlocking with the electronic key 31 is referred to as manual release of the security mode. Note that if the second operation is not performed within the time limit after the first operation is performed, the controller 40 determines that an abnormal state has occurred. In this case, warning processing is executed in the same manner as when the front door 16 is opened. Therefore, the controller 40 and the speaker 29 constitute the second warning means.

In addition, this locking/unlocking system is provided with an extension function for extending the time limit for performing the first operation and the second operation. Specifically, the extension function is a function that extends the time limit by performing an extension operation within the time limit after the first operation is performed. In this embodiment, the extension operation is assumed to be contact with the touch sensor 18 . Therefore, the touch sensor 18 corresponds to operation means.

In this embodiment, when manually canceling the alert mode (that is, when unlocking the locking devices 21 and 22 within the time limit), the covers 17a and 17b provided on the door handle 17 are opened, and the cylinders are closed. Portions 21a and 22a must be exposed. When the user opens the two covers 17a and 17b and then performs the first operation and the second operation, there is time to spare with respect to the time limit. When the other cover 17a, 17b is opened after the operation is performed (hereinafter referred to as a poorly arranged method), there is no time margin for the time limit. A user who is unfamiliar with manually canceling the alert mode is more likely to try to perform the procedure in a poorly organized manner. In this case, the first operation and the second operation cannot be performed within the time limit, and the warning process is executed. There is a risk that In this locking/unlocking system, since the time limit can be extended by the extension function, even an inexperienced user can manually cancel the alert mode.

Next, the content of control processing executed by the controller 40 will be described with reference to FIG. FIG. 3 is a flow chart showing the flow of manual cancellation processing of the alert mode. This process is repeatedly executed at a predetermined time period (for example, 0.5 seconds). When the electronic key 31 is used to cancel the alert mode, the electronic key 31 is used to unlock the door. Therefore, the process of canceling the alert mode using the electronic key 31 is not included in the control process of FIG.

As shown in FIG. 3, in step S11, it is determined whether or not the alert mode is set. If the caution mode is set, the process proceeds to step S12. If the alert mode is not set, the process ends.

In step S12, it is determined whether or not the entrance door 16 has been opened. When an open detection signal is input by the open/close detection sensor 28, it is determined that the entrance door 16 has been opened, and the process proceeds to step S14. If an open detection signal is not input by the open/close detection sensor 28, it is determined that the entrance door 16 is not opened, and the process proceeds to step S13.

In step S14, warning processing is performed. The case where the process proceeds from step S12 to step S14 means that the front door 16 is opened without being unlocked by the electronic key 31 under the setting state of the alert mode. Therefore, in this case, warning processing is executed in the warning mode. In other words, it transmits a request for transmitting a warning sound to the speaker 29 . When the speaker 29 receives the warning sound transmission request, the speaker 29 transmits the warning sound for a predetermined period of time (for example, one minute). As a result, a person near the entrance door 16 on the outdoor side is warned. Note that the warning process when proceeding from step S12 to step S14 corresponds to first warning means. After executing the warning process, the process ends.

In step S13, it is determined whether or not the first operation has been performed. Here, the first operation is an unlocking operation for one of the locking devices 21 and 22 . Therefore, it is determined whether or not the unlock detection signal transmitted by either one of the lock/unlock sensors 26 and 27 has been received. When the unlock detection signal is received, it is assumed that one of the locking devices 21 and 22 is unlocked, that is, the first operation is performed, and the process proceeds to step S15. If the unlock detection signal has not been received, it is assumed that neither of the locking devices 21 and 22 has been unlocked, that is, the first operation has not been performed, and this processing ends.

In step S15, it is determined whether or not it is within the time limit. Here, when the first operation has been performed, the timer 42 starts to count time immediately after it is determined that the first operation has been performed. In this step, it is determined whether or not the time measured by the timer 42, that is, the time from the execution of the first operation to the time in this step is within the time limit. The time limit is the time required to perform the first operation and the second operation, or a time shorter than the required time. The time limit is, for example, 5 to 15 seconds, and is set to 10 seconds in this embodiment.

When the time counted by the timer 42 exceeds the time limit in step S15, the process proceeds to step S14 to execute warning processing. A case where the time counted by the timer 42 exceeds the time limit corresponds to a case where the second operation is not performed within the time limit after the first operation is performed in step S13. Therefore, in this case, warning processing is executed in the warning mode. Although the details of the warning processing are omitted because they have been described above, the speaker 29 emits a warning sound at a predetermined time to warn a person near the entrance door 16 on the outdoor side. Note that the warning process when proceeding from step S15 to step S14 corresponds to second warning means. After the warning process, the process ends.

If the time measured by the timer 42 is within the time limit in step S15, the process proceeds to step S16. In step S16, it is determined whether or not an extension operation has been performed. When the detection result from the touch sensor 18 (that is, the detection result indicating that a person has touched the touch sensor 18) is input, it is determined that the extension operation has been performed, and the process proceeds to step S17. If the detection result from the touch sensor 18 has not been input, it is assumed that the extension operation has not been performed, and the process proceeds to step S20.

In step S17, the count number C is incremented by one. The count number C has an initial value of 0, and means "the number of extension operations" counted based on the extension operation being performed in step S16. That is, in step S17, the count number C is incremented by 1 because the extension operation has been performed in step S16. The extension operation in step S16 is a process that can be repeated when the process returns to step S15 in step S20, which will be described later. Therefore, the count number C of the extension operation may be 1, for example, and in this case, 1 is added to the count number C to 2 in step S17. In the case of the first extension operation, the count number C of the extension operation is 0, and in this case, 1 is added to the count number C to make it 1 in step S17.

In step S18, it is determined whether or not the count number C is less than a predetermined numerical value (threshold value TH) (corresponding to extension prohibiting means). In this embodiment, the number of extensions of the time limit is limited. For example, when the time limit can be extended up to three times, the predetermined numerical value (threshold TH) is four. When the count number C is less than the predetermined numerical value, the process proceeds to step S19. If the count number C is not less than the predetermined numerical value (that is, if it is equal to or greater than the predetermined numerical value), the process proceeds to step S20.

In step S19, extension of the time limit is executed by adding an extension time to the time limit (corresponding to time extension means). Here, the extension of the time limit is executed based on the execution of the extension operation in step S16. The extension time is, for example, 3 to 8 seconds, and is set to 5 seconds in this embodiment. For example, if the remaining time limit is 8 seconds and the extension time is 5 seconds at the time of step S16, the extension time is added to the time limit in this step, and the remaining time limit is set to 13 seconds. Further, in this embodiment, the total time limit is 15 seconds by the first extension operation, the total time limit is 20 seconds by the second extension operation, and the total time limit is 20 seconds by the third extension operation. is 25 seconds.

If the extension operation has not been performed in step S16, if the count C is not less than the predetermined value in step S18, and if the time limit has been extended in step S19, the process proceeds to step S20. In step S20, it is determined whether or not the second operation has been performed.

Here, the second operation is the unlocking operation for the locking device 21, 22 which is not unlocked in step S13, that is, the other of the locking devices 21, 22. . Therefore, it is determined whether or not the unlock detection signal transmitted by the other of the lock/unlock sensors 26 and 27 has been received. When the unlock detection signal is received by the other of the lock/unlock sensors 26, 27, it is determined that the other of the locking devices 21, 22 is unlocked, that is, the second operation is performed, and the process proceeds to step S21. move on. If the other of the locking/unlocking sensors 26 and 27 does not receive the unlock detection signal, it is assumed that the other of the locking devices 21 and 22 is not unlocked, that is, the second operation is not performed. End this process.

In step S21, based on the fact that the first operation and the second operation are performed within the time limit, the caution mode is canceled (corresponding to mode canceling means). After canceling the alert mode, the process ends.

FIG. 4 is a time chart more specifically showing the warning mode manual cancellation process. It should be noted that in FIG. 3, the setting of the alert mode at time t1 is based on the fact that the electronic key 31 has been locked.

In FIG. 4, after the alert mode is set at time t1, the user performs the first operation (that is, unlocking one of the locking devices 21 and 22) at time t2. As a result, the timer 42 starts measuring time at time t2. At this time, the time limit is set to 10 seconds.

Then, at time t3, the user performs an extension operation (that is, touching the touch sensor 18). This will extend the time limit by 5 seconds. After time t3, the user also performs an extension operation (that is, contact on the touch sensor 18) at time t4 and time t5. As a result, the time limit is further extended by 5 seconds, bringing the total time limit to 25 seconds.

At time t6, which is within the time limit after time t5, the user performs the second operation (that is, unlocking the other of the locking devices 21 and 22). This cancels the alert mode. Note that in this case, the warning process remains unexecuted.

According to this embodiment detailed above, the following excellent effects are obtained.

According to the present embodiment, two operations (first operation and second operation) using the mechanical key 32 can be performed within the time limit in order to cancel the alert mode without unlocking the electronic key 31 (manually). It is required and this ensures security. Further, according to the present embodiment, when the first operation and the second operation required for manually canceling the alert mode cannot be performed within the time limit, the time limit is extended by performing the extension operation. . As a result, when the user is not accustomed to manually canceling the alert mode, the time limit can be extended, and the time for performing the second operation can be secured. Also, by making it possible to extend the time limit, it is possible to shorten the time initially set as the time limit. For example, there is concern that the mechanical key 32 may be unlocked illegally by picking or the like. In this case, since the fraudulent person does not know the extension function, the time limit is not extended, and the time limit remains short for the fraudulent person. As a result, the unauthorized person cannot cancel the alert mode within the time limit, and a warning process is executed for the unauthorized person. Therefore, according to the present embodiment, it is possible to secure security and improve convenience for the user.

- According to this embodiment, two locking devices 21 and 22 are provided, the first operation is the locking/unlocking operation in one of the locking devices 21 and 22, and the second operation is the locking device 21 and 22. is the locking/unlocking operation in either one of the two. Therefore, by locking and unlocking both of the two locking devices 21 and 22 with the mechanical key 32 within the time limit, the alert mode is canceled. As a result, a user who does not possess the electronic key 31 can manually release the alert mode as the mechanical key 32 is used to unlock the two locking devices 21 and 22 in order to enter the house 10.例文帳に追加. That is, when two locking devices 21 and 22 are provided, unlocking the two locking devices 21 and 22 by a legitimate method other than unlocking with the electronic key 31 (that is, unlocking operation with the mechanical key 32 ) cancels the alert mode. Therefore, there is no need to perform an operation to cancel the alert mode, and convenience for the user can be improved.

- According to the present embodiment, after extending the time limit a predetermined number of times, extension of the time limit is prohibited. That is, the number of extensions of the time limit is limited. As a result, it is possible to prevent the time limit from being infinitely extended, thereby ensuring security.

・According to the present embodiment, the extension operation is contact with the touch sensor 18 provided on the door handle 17, and the touch sensor 18 is located at a location different from the cylinder portions 21a and 22a that perform the first operation and the second operation. is provided in As a result, when an unauthorized person tries to cancel the alert mode (unlock the locking devices 21 and 22) by the first operation and the second operation, it is possible to avoid accidentally performing the time extension operation. Crime prevention can be improved.

- According to this embodiment, the touch sensor 18 used when locking/unlocking with the electronic key 31 is utilized as the touch sensor 18 operated (contacted) for time extension operation. That is, the touch sensor 18 that is touched by the user for locking/unlocking by the electronic key 31 and the touch sensor 18 that is operated (touched) for the time extension operation are shared. Therefore, this makes it possible to extend the time limit without requiring new equipment.

(Other embodiments)
For example, the above embodiment may be modified as follows.

(1) In the above embodiment, the first operation and the second operation are unlocking operations in the two locking devices 21 and 22, but the first operation and the second operation are not limited to this. For example, inserting the mechanical key 32 into one of the cylinder portions 21a and 22a, unlocking and locking with the mechanical key 32, unlocking, locking, and unlocking with the mechanical key 32, etc. It may be an operation or a second operation.

(2) In the above embodiment, the first operation is the unlocking operation of one of the locking devices 21 and 22, and the second operation is the unlocking operation of the other of the locking devices 21 and 22. Locking devices 21, 22 on which the 1st operation and the 2nd operation are performed may be defined. For example, the first operation may be the unlocking operation of the locking device 21 and the second operation may be the unlocking operation of the locking device 22 . In this case, to cancel the alert mode, it is necessary to unlock the locking device 22 defined as the second operation of the two locking devices 21 and 22 after unlocking the locking device 21 defined as the first operation. . Therefore, since the method of manually canceling the alert mode is more limited, it is possible to improve crime prevention.

(3) In the above embodiment, the extension operation is a contact on the touch sensor 18, but the operation means and extension operation are not limited to this. For example, a button incorporating a contact type sensor may be provided near the entrance door 16 on the outdoor side, and pressing the button (operation means) may be the extended operation.

(4) In the above embodiment, only one operation (contact on the touch sensor 18) is defined as the extension operation. The configuration may be such that either is selected (changed) as a normal extension operation. For example, as the extension operation on the touch sensor 18, a plurality of aspects of the extension operation can be determined by changing the number of times of contact (continuous contact) and the contact time of the touch sensor 18. FIG. Moreover, if the touch sensor 18 is configured to detect a plurality of contact points, it is possible to determine a plurality of modes of the extension operation on the touch sensor 18 by changing the number of the contact points. Further, as the extension operation, touching on the touch sensor 18 and operation on other operation means (for example, a button provided near the entrance door 16 and pressing the button) may be defined. In other words, a plurality of extension operations may be defined, and there may be a plurality of operating means for the extension operations.

In addition, when a plurality of forms of the extension operation are defined, means for selecting (changing) the regular extension operation from among them is not particularly limited. For example, the user may appropriately select (change) the normal extension operation, the normal extension operation may be determined for each user, or the normal extension operation may be performed periodically (every time period, every predetermined number of days). It may be a configuration in which the extension operation of is changed. Further, after locking/unlocking with the mechanical key 32 for which the extension operation has been performed, a regular extension operation may be selected (changed). In these cases, any operation other than the normal extension operation is not recognized as an extension operation, and the extension of the time limit is not executed. There is no particular limitation on the method by which the user knows which extension operation is the normal extension operation.

For the user, it is desirable that the time extension operation be simple, but there is a concern that such a simple operation may reduce security. Also, if an unauthorized person observes that the user is performing the extension operation, there is a concern that the unauthorized person will recognize the extension operation. According to this configuration, for example, it is possible to change the extended operation every day. This makes it difficult for an unauthorized person to recognize the extension operation, and as a result, it is possible to improve crime prevention.

(5) In the above embodiment, the locking/unlocking system is intended for a residential building 10, but the building to which the locking/unlocking system of the present invention is applied is not limited to the residential building 10. For example, a commercial building. , or a building such as a warehouse.
