Description

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

In buildings such as houses, a locking / unlocking system for locking / unlocking a locking device provided on a door using an electronic key having a wireless function has been put into practical use. In recent years, it is known that a touch sensor is built in a door knob provided on the outdoor side of a door and is locked and unlocked by contact with the sensor. In this system, when a resident carrying an electronic key approaches a door to enter a building and enters the communication area of a communication device provided near the door, the identification information transmitted from the electronic key is transmitted by the communication device. Received. Then, on the building side, authentication of whether or not the person is a resident is performed based on the identification information received via the communication device, and the authentication determines that the person is a resident, and the resident becomes a doorknob. When the touch is detected by the touch sensor, the locking device provided on the door is locked and unlocked.

According to such a system, the locking device is locked and unlocked simply by touching the doorknob on the outdoor side, which is excellent in convenience. However, for example, a resident carrying an electronic key near the entrance on the indoor side (for example, immediately after returning home). If the resident) remains, the communication device communicates with the electronic key and authenticates the electronic key. In such a case, the locking device can be locked and unlocked only by touching the doorknob from the outdoor side (for example, a suspicious person) without holding the electronic key. Therefore, such a situation may be locked and unlocked regardless of the intention of the resident, which is not preferable for crime prevention.

In order to avoid such a situation, for example, a technology that detects the presence of a person near the entrance on the indoor side and does not allow unlocking even if the electronic key is authenticated when the person is detected. It is known (for example, Patent Document 1). In such a technique, a pyroelectric infrared sensor is often used for detecting the presence of a person. Since the sensor detects the presence of a person by detecting the temperature change with the surroundings in the detection area, the presence may not be detected while the person is stationary, so the detection accuracy is sufficient. I can't say. Therefore, as a means of ensuring crime prevention in consideration of the detection accuracy, a technique has been proposed in which once the sensor detects a person, the unlocking state that prohibits unlocking by contact with the doorknob is continued for a predetermined period. ing.

Japanese Unexamined Patent Publication No. 2017-120001

However, with the above technology, for example, when a resident living together near the entrance on the indoor side crosses, the lock cannot be unlocked for a predetermined period of time regardless of the safety problem, and the person returns home immediately afterwards. Residents cannot unlock by touching the doorknob. In this case, the resident who has returned home needs to take out the electronic key from the bag or the like and operate the remote operation switch provided on the electronic key or wait for a predetermined period until the unlockable state is released. There is a situation where the convenience cannot be fully utilized.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a building locking / unlocking system capable of improving convenience without impairing crime prevention.

In order to solve the above problems, the building locking / unlocking system of the first invention is
It is applied to a building equipped with an opening / closing body that opens / closes the entrance / exit of the building and a locking device that locks the opening / closing body.
An electronic key that is carried by the user and sends unique identification information,
A communication device capable of wireless communication with the electronic key using a predetermined range near the entrance / exit of the building as a communication area.
A control means for controlling locking / unlocking based on the identification information from the electronic key received by the communication device, and
A person detecting means for detecting the presence of a person in the vicinity of the doorway in the building, and
Equipped with
When the control means detects the presence of a person by the person detection means, the control means invalidates the unlocking operation based on the identification information for a predetermined invalid period after the presence of the person is detected. It is a locking and unlocking system for buildings that are equipped.
When the control means satisfies a predetermined release condition set by the communication status with the electronic key or the open / close status of the opening / closing body and the detection result from the person detecting means, before the invalid period elapses. It is characterized in that the unlocking means for canceling the invalidation of the unlocking operation performed by the invalidation means is provided.

In the conventional locking / unlocking system, it has been determined to continue disabling the unlocking operation only by the presence or absence of a person near the doorway on the indoor side. Therefore, even if there is no problem in crime prevention, the unlocking operation is invalidated for a predetermined invalidation period, which may impair convenience. However, according to the first invention, even during the invalid period, a predetermined release condition set by the communication status with the electronic key or the open / closed status of the open / close body and the detection result from the human detecting means is satisfied. And the invalidation of the unlocking operation can be canceled.

That is, according to the first invention, it is not necessary to invalidate the unlocking operation by combining the presence / absence of a person near the doorway on the indoor side with the communication status with the electronic key or the opening / closing status of the opening / closing body. The situation, in other words, the situation where there is no problem even if the locking device is unlocked for crime prevention can be grasped. Then, in a situation where there is no such problem in crime prevention and it is not necessary to invalidate the unlocking operation, the invalidation of the unlocking operation can be canceled, and thus the convenience is improved without impairing the crime prevention property. Can be done.

In the first invention, the building locking / unlocking system of the second invention receives the identification information from the electronic key in the situation where the unlocking operation is invalidated by the invalidating means as the unlocking condition. It is characterized in that the case where it is not received is set.

For example, when a cohabiting resident in a building is detected by a person detecting means across the vicinity of the entrance, the unlocking operation is invalidated for a predetermined period. Therefore, even if the resident leaves the vicinity of the entrance immediately after being detected by the person detection means, the resident who returns home immediately after leaving the door can unlock the key based on the identification information of the electronic key by disabling the unlocking operation. Cannot be operated (for example, unlocking by touching the doorknob based on the identification information of the electronic key). Therefore, the resident who returned home had to wait until the invalid period had passed.

However, according to the second invention, the identification information from the electronic key is not received after the resident in the building leaves the vicinity of the entrance and before the invalid period elapses (in other words, the legitimate electronic key. The invalidation of the unlocking operation is canceled on condition that the communication is not established. As a result, for example, a resident who returns home immediately after a resident in a building crosses the vicinity of the entrance and returns home can perform an unlocking operation based on the identification information of the electronic key (for example, a solution by contacting a doorknob based on the identification information of the electronic key). It is possible to reduce the situation where the unlocking operation cannot be performed even if the lock is tried, that is, the situation where the unlocking operation is invalidated even though there is no problem in terms of crime prevention. Therefore, convenience can be improved without impairing crime prevention.

According to a third aspect of the invention, in the second invention, after the control means determines that the release condition is satisfied, a waiting period set shorter than the invalid period elapses, and then the unlocking operation is invalidated. It is characterized in that the conversion is released by the release means.

According to the third invention, when the invalidation is canceled on condition that the electronic key is not authenticated in the situation where the unlocking operation is invalidated, the waiting period shorter than the invalidation period is from the electronic key. Waits for whether or not the identification information of is received. That is, even if the identification information from the electronic key is not received, the communication from the electronic key is waited for a short period of time.

For example, in a situation where a resident carrying an electronic key is detected by a human detection means, for some reason (for example, there are multiple electronic keys or a device that generates radio waves is nearby. If there is a delay in the communication between the electronic key and the communication device due to the reason), there may be a time lag between the detection of the person by the person detecting means and the communication with the electronic key. Even in such a case, the unlocking operation is not immediately invalidated on condition that the identification information is not received from the electronic key. Therefore, according to the third invention, safety can be enhanced.

In the second or third invention of the building locking / unlocking system of the fourth invention, the detection area in which the presence of a person is detected by the person detecting means includes the communication area on the indoor side of the communication device. It is characterized in that it is set as follows.

According to the fourth invention, on the indoor side near the entrance, the detection area in which the person detecting means detects a person is set to include the communication area in which the electronic key is authenticated. As a result, the electronic key carried by the resident who stays indoors near the entrance is authenticated, and the situation where the person is not detected by the person detecting means can be avoided. That is, there is a security problem that the unlocking operation is not invalidated even though the unlocking operation can be performed from the outdoor side based on the identification information of the electronic key existing on the indoor side. It can be avoided.

The building locking / unlocking system of the fifth invention is the invention of any one of the first to fourth aspects.
An opening / closing detecting means for detecting the opening / closing of the opening / closing body is provided.
As the release condition, in a situation where the unlocking operation is invalidated by the invalidation means, it is detected that the opening / closing body is opened / closed by the opening / closing detecting means, and after the opening / closing body is closed, the person. It is characterized in that a case where a person is not detected by the detection means is set.

For example, a resident carrying an electronic key may notice something left behind and try to return to the building immediately after opening and closing the opening / closing body to go out. In this case, since the resident is detected by the person detecting means in the building immediately before that, the unlocking operation is invalidated. Therefore, in such a case, the resident had to wait for the invalid period to elapse in order to unlock.

However, in such a situation, even if the unlocking operation continues to be invalidated, there is no person near the doorway in the building, and there is no electronic key in the communication area of the communication device in the building. Therefore, in such a situation, even if the locking device is unlocked by the unlocking operation based on the identification information of the electronic key, there is no problem in crime prevention.

Therefore, according to the fifth invention, in a situation where the unlocking operation is invalidated, if a person is not detected near the doorway on the indoor side by the person detecting means after the opening / closing body is opened / closed, the unlocking operation is performed. Cancel the invalidation of. As a result, when a resident who intends to go out tries to return to the building to pick up a forgotten item, the unlocking operation based on the identification information of the electronic key becomes possible without waiting for the expiration of the invalid period. That is, it is possible to reduce the situation where the unlocking operation is invalidated even though there is no problem in crime prevention, and the convenience can be improved without impairing the crime prevention.

The building locking / unlocking system of the sixth invention is the invention of any one of the first to fifth aspects, wherein the locking device is locked / unlocked from the inside of the building at the entrance / exit by an operation by an operation unit provided inside the building. It is characterized by being configured to be.

For example, even when a resident living together greets a resident who has returned home near the doorway on the indoor side, the unlocking operation is invalidated because the person is detected by the person detecting means. Therefore, the resident who has returned home cannot unlock the locking device from the outdoor side even if he / she carries the electronic key. According to the sixth invention, in such a case, the welcoming resident can operate the operation unit provided on the indoor side from the indoor side to unlock the locking device. Therefore, there is no major inconvenience for the resident who has returned home, and convenience is ensured without impairing crime prevention.

Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. Note that FIG. 1 is a plan view showing the vicinity of the entrance.

As shown in FIG. 1, the building 10 is provided with an entrance portion 11, a corridor 12, a living room 13, and the like as indoor spaces. The entrance portion 11 is provided with an entrance entrance 15 as an entrance / exit. It is possible to enter and exit the building 10 through this entrance 15. Further, the entrance 15 is provided with an entrance door 16 as an opening / closing body. The entrance door 16 is composed of, for example, a rotary hinged door. The entrance door 16 opens and closes the entrance door 15. The entrance door 16 may be a sliding door.

The entrance door 16 is provided with a doorknob 18 as a handle on the outdoor side. The doorknob 18 has a built-in doorknob sensor 19 including a touch sensor that detects that a person has touched the doorknob 18.

The entrance door 16 is provided with a locking device 21. The locking device 21 is a device that locks and unlocks the entrance door 16 by electrically locking and unlocking the lock. The locking device 21 is locked and unlocked by an electronic key 41 carried by a resident of the building 10. Further, the locking device 21 has a thumb turn portion 21a that can be locked and unlocked from the indoor side (entrance portion 11 side). In the present embodiment, when the locking device 21 is locked / unlocked from the indoor side, it is locked / unlocked by operating the thumb turn portion 21a.

A communication device 31 is provided on the outdoor side near the entrance door 16 (the surface on the outdoor side of the entrance door 16 is also possible). The communication area CA for wireless communication in the communication device 31 is a predetermined circular range centered on the communication device 31 in a plan view, and the range is set so as to straddle the indoor side and the outdoor side of the entrance 15. ing. Specifically, the communication area CA of the communication device 31 is set so that when the resident grabs the doorknob 18 on the outdoor side of the entrance door 16, the resident is located in the communication area CA. The communication device 31 is capable of communicating with the electronic key 41 within the communication area CA.

The electronic key 41 is provided with a lock switch 42 for locking and an unlock switch 43 for unlocking as an operation unit for locking / unlocking the locking device 21 by remote operation. The electronic key 41 can transmit an operation signal for locking or unlocking based on the pressing operation of the locking switch 42 or the unlocking switch 43.

A motion sensor 23 is provided on the indoor side of the entrance 15 (for example, the upper part of the indoor side surface of the wall provided with the entrance 15). The motion sensor 23 is configured to detect the presence of a person in the vicinity of the entrance 15. Examples of the human sensor 23 include a pyroelectric infrared sensor that detects infrared rays from the human body, an ultrasonic sensor that detects a person by outputting ultrasonic waves and receiving ultrasonic waves reflected by the human body, and the like. Used.

While the communication device 31 uses the inside and outside of the building 10 as the communication area CA, the motion sensor 23 has the arrangement position and detection range so that only the inside of the building 10 is the detection area DA when the entrance door 16 is closed. Is set. Further, when the resident enters the entrance portion 11 to go out, the respective ranges are set so as to first enter the detection area DA of the motion sensor 23 and then enter the communication area CA of the communication device 31. It has been adjusted.

An open / close detection sensor 24 for detecting the opening / closing of the entrance door 16 is provided on the indoor side surface of the entrance door 16.

Subsequently, the electrical configuration of the locking / unlocking system will be described with reference to FIG. FIG. 2 is a diagram showing an electrical configuration of a locking / unlocking system.

As shown in FIG. 2, the locking / unlocking system includes a controller 32 as a locking / unlocking control means. The controller 32 is configured to include a well-known microcomputer having a CPU or the like, and is provided, for example, on the wall surface of the entrance portion 11. The controller 32 measures at least a time with a control unit 33 that controls locking and unlocking, a storage unit 34 that stores ID information (identification information) for electronic key authentication, detection results from various sensors, and the like. It has a timer 35 used for the above.

A communication device 31 is connected to the controller 32. The communication device 31 is capable of wireless communication with the electronic key 41 carried by each resident living in the building 10. In this case, the controller 32 is capable of wireless communication with each resident's electronic key 41 via the communication device 31.

The electronic key 41 includes a memory (not shown) that stores ID information unique to each electronic key 41, and transmits ID information in response to a request from the controller 32. Here, the communication device 31 transmits the request signal at a predetermined time cycle (for example, every 0.5 seconds), whereas the electronic key 41 enters the communication area CA, which is the communication area of the communication device 31. When the request signal is received, the ID information is transmitted to the communication device 31 in response to the request signal. Then, when the ID information is received by the communication device 31, the ID information is input from the communication device 31 to the controller 32. When the ID information from the electronic key 41 is input via the communication device 31, the controller 32 determines a match between the ID information and the ID information registered in advance in the storage unit 34, and uses the regular electronic key 41 to determine the match. Authenticate whether or not it exists.

A doorknob sensor 19 is connected to the controller 32. The sequential detection result is input to the controller 32 from the doorknob sensor 19. Then, when the detection result (indicating that a person has touched the doorknob 18) is input from the doorknob sensor 19 in the situation where the electronic key 41 is properly authenticated by the above ID information, the controller 32 locks the locking device 21 or locks the locking device 21. Unlock. That is, when the detection result from the doorknob sensor 19 is input while the locking device 21 is locked, the locking device 21 is unlocked, and when the locking device 21 is unlocked, the detection result is obtained from the doorknob sensor 19. When input, the locking device 21 is locked. If the electronic key 41 does not correspond to a legitimate one, the locking device 21 is not locked or unlocked.

The controller 32 can also lock and unlock the locking device 21 by receiving an operation signal for locking or unlocking transmitted from the electronic key 41. That is, the electronic key 41 transmits an operation signal for locking by pressing the lock switch 42 for locking, and the operation signal for unlocking is transmitted by pressing the unlock switch 43 for unlocking. Send. Then, when the operation signal from the electronic key 41 is received by the communication device 31, the controller 32 locks and unlocks the locking device 21 based on the operation signal. In the present specification, locking / unlocking the locking device 21 based on the operation signal from the electronic key 41 may be referred to as “remote operation”. For remote operation, the locking device 21 can be locked and unlocked from either the outdoor side or the indoor side.

A motion sensor 23 is connected to the controller 32. The sequential detection result is input to the controller 32 from the motion sensor 23. The controller 32 determines the presence or absence of a person in the detection area DA of the motion sensor 23 based on the detection result from the motion sensor 23.

An open / close detection sensor 24 is connected to the controller 32. The sequential detection result is input to the controller 32 from the open / close detection sensor 24. Based on the detection result from the open / close detection sensor 24, the open / closed state of the entrance door 16 is determined. When it is determined that the entrance door 16 is closed, the entrance door 16 may be automatically locked (auto-locked) by the locking device 21.

Next, the contents of the control process executed by the control unit 33 of the controller 32 will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing the flow of the control process of the unlocking disallowed mode in which the unlocking of the locking device 21 is disallowed. FIG. 4 is a flowchart showing the flow of control processing in locking / unlocking the locking device 21.

The unlock disapproval mode is implemented when a person is detected by the motion sensor 23. While the unlock disapproval mode is being executed, the locking device 21 is not unlocked even when the electronic key 41 is properly authenticated and the contact by the doorknob 18 is detected by the doorknob sensor 19. In other words, the unlock disapproval mode makes it impossible to unlock the locking device 21 by contact with the doorknob 18 in a situation where the electronic key 41 is properly authenticated by the ID information. Even when the unlocking disallow mode is implemented, the unlocking can be performed by remote operation of the electronic key 41.

When the unlocking disallowed mode is implemented, there are three conditions for canceling the unlocking disallowed mode;
(A) After the detection of the person, the ID information from the electronic key 41 is received, the predetermined time T1 has elapsed from the detection of the person, and the human sensor 23 has not detected the person after the predetermined time T1 has elapsed;
(B) After the detection of the person, the predetermined time T2 has elapsed in a situation where the ID information from the electronic key 41 has not been received, and the human sensor 23 has not detected the person after the predetermined time T2 has elapsed (here, T2). <T1);
(C) After the person is detected, the ID information from the electronic key 41 is received, and the person is not detected by the motion sensor 23 after opening and closing the entrance door 16.

That is, when a person is detected by the motion sensor 23 at the entrance portion 11, the unlocking disallowance mode is executed until a predetermined time T1 elapses from the detection of the person. At that time, if the predetermined condition (b) or (c) is satisfied, the unlocking disapproval mode is canceled before the predetermined time T1 elapses.

Hereinafter, the conditions (a) to (c) for releasing the unlocking disallowed mode will be described with reference to the flowchart of FIG.

As shown in FIG. 3, in step S11, it is determined whether or not the presence of a person is detected by the motion sensor 23. If the presence of a person is detected, the process proceeds to step S12. If the presence of a person is not detected, this process ends.

In step S12, the unlocking disallowed mode is started. After starting the unlocking disallowed mode, the process proceeds to step S13.

In step S13, the timer 35 is set and the time counting by the timer 35 is started. After the start of timekeeping, the process proceeds to step S14.

In step S14, the ID information from the electronic key 41 is received via the communication device 31, and it is determined whether or not the result of the authentication process of the ID information is OK. If the authentication is OK, YES is determined in step S14, and the process proceeds to step S15. If the ID information is not received, or if the authentication is NG, a NO determination is made and the process proceeds to step S16. In the following, "authentication of the electronic key 41" may be referred to as "reception of ID information from the electronic key 41".

Here, when the motion sensor 23 detects a person and the ID information from the electronic key 41 is not received (that is, NO determination in step S14), the person detected by the motion sensor 23 is the electronic key 41. It is considered that either the user does not carry the electronic key 41 or the electronic key 41 exists outside the communication area CA of the communication device 31 regardless of whether or not the electronic key 41 is carried. In this case, since the electronic key 41 is not authenticated in either case, the locking device 21 cannot be locked or unlocked by the contact of the doorknob 18. That is, even if a person is present near the entrance door 16 on the indoor side, there is no problem in crime prevention. The NO determination in step S14 corresponds to the condition (b) in which the unlocking disallowed mode is released (note that it is necessary to go through steps S16 and S18 after step S14, but that point. Will be described later).

In step S16, it is determined whether or not the elapsed time from the start of time counting by the timer 35 exceeds the predetermined time T2. That is, here, it is determined whether or not a predetermined time T2 has elapsed since the person was detected by the motion sensor 23. The predetermined time T2 is shorter than the predetermined time T1 in step S17 described later, and is set to, for example, about 5 seconds. Here, it is confirmed that "after a predetermined time T2 has elapsed from the detection of the person by the motion sensor 23 in step S11" under the condition (b) in which the unlocking disallowance mode is released. If a predetermined time T2 has elapsed since the person was detected by the motion sensor 23, the process proceeds to step S18. If T2 has not elapsed since the detection of the person by the motion sensor 23, the process returns to step S14, and each process is repeated.

In step S15, it is determined whether or not the entrance door 16 is opened and then closed within a certain period of time after the human sensor 23 detects a person. When the entrance door 16 is opened and then closed, the determination in step S15 is YES, and the process proceeds to step S18. If the entrance door 16 is open and then not closed, NO determination is made in step S15, and the process proceeds to step S17.

In step S17, it is determined whether or not the elapsed time from the start of time counting by the timer 35 exceeds the predetermined time T1. That is, here, it is determined whether or not the predetermined time T1 has elapsed from the detection of the person by the motion sensor 23 in step S11. The predetermined time T1 is set to, for example, about 10 seconds. When the predetermined time T1 has elapsed from the detection of the person by the motion sensor 23, the process proceeds to step S18. If T1 has not elapsed since the detection of the person by the motion sensor 23, the process returns to step S14, and each process is repeated.

When the motion sensor 23 detects a person and the ID information from the electronic key 41 is received (that is, YES determination in step S14), for example, (1) a resident who has returned home carrying the electronic key 41. Is staying at the entrance 11 or (2) a resident carrying the electronic key 41 has entered the entrance 11 to go out. In these situations (1) and (2), when a suspicious person who does not carry the electronic key 41 comes into contact with the doorknob 18 from the outdoor side, the electronic key 41 carried by the resident who remains at the entrance 11 is officially authenticated. Therefore, the locking device 21 is unlocked.

Therefore, in order to avoid such a situation, if the electronic key 41 is authenticated while the unlock disapproval mode is being executed (YES determination in step S14), unlocking is performed until the predetermined time T1 elapses. Maintain disallowed mode. Therefore, in step S17, the passage of the predetermined time T1 is determined. The YES determination in step S17 corresponds to the condition (a) in which the unlocking disapproval mode is released (note that it is necessary to go through step S18 after step S17, but this is the point. Will be described later).

In the case of (2), if the entrance door 16 is opened and closed before the lapse of the predetermined time T1 in order for the resident to go out, a YES determination is made in step S15, and the process proceeds to step S18.

In step S18, it is determined whether or not the presence of a person is detected by the motion sensor 23. If the presence of a person is not detected, a YES determination is made and the process proceeds to step S19. If the presence of a person is detected, a NO determination is made, the process returns to step S13, and each process is repeated.

If it is determined in step S18 that no person has been detected by the motion sensor 23, the process proceeds to step S19, and in step S19, the unlocking disallowance mode is released. After canceling the unlocking disallowed mode, this process ends.

Here, when the opening / closing of the entrance door 16 is detected (YES determination in step S15) and the process proceeds to step S18, and no person is detected by the motion sensor 23 (YES determination in step S18), the entrance in step S11. It is probable that the person detected in Part 11 went out. That is, since the resident carrying the electronic key 41 (corresponding to the YES determination in step S14) opens the entrance door 16 to the outdoor side and then closes the entrance door 16 (YES determination in step S15), the human feeling. It can be inferred that the sensor 23 does not detect a person at the entrance portion 11.

Therefore, in such a case, the electronic key 41 does not exist in the communication area CA on the indoor side, and the resident carrying the electronic key 41 stays near the entrance door 16 on the outdoor side (that is, the outdoor side). The electronic key 41 exists in the communication area CA of the above). Therefore, it is unlikely that a suspicious person will come into contact with the doorknob 18 from the outdoor side to unlock the locking device 21. Therefore, in such a case, there is no problem in crime prevention even if the unlocking disallowed mode is canceled. If the process proceeds from step S15 to S18 and no person is detected by the motion sensor 23 (YES determination in step S18), the condition of (c) that the unlocking disapproval mode is released is satisfied. In this case, assuming that the condition (c) is satisfied, the unlocking disapproval mode is released before the lapse of the predetermined time T1 (step S219).

Further, when the process proceeds from steps S14 and S16 to step S18, in the step S18, the identification information from the electronic key 41 is not received under the condition of (b), and a predetermined time T2 elapses from the detection of the person in step S11. Later, it was confirmed that "a person is not detected by the motion sensor 23". Therefore, in this case, the unlocking disallowed mode is released by determining YES in step S18, and the unlocking disallowed mode is satisfied after the predetermined time T2 has elapsed, which is before the predetermined time T1 has elapsed. Is released (step S19).

When the process proceeds from step S17 to step S18 and no person is detected by the motion sensor 23 (YES determination in step S18), the condition (a) in which the unlock disapproval mode is canceled is satisfied. In step S18, under the condition of (a), the identification information from the electronic key 41 is received, and it is confirmed that "the person is not detected by the motion sensor 23" after a predetermined time T1 has elapsed from the detection of the person in step S11. ing. That is, the unlocking disallowance mode is released after a predetermined time T1 has elapsed from the detection of the person by the motion sensor 23 in step S11 (step S19).

As described above, in the present embodiment, the unlocking disapproval mode is executed at the predetermined time T1 when a person is detected by the motion sensor 23 (YES determination in step S14, NO determination in step S15). , Proceed to step S18 via the YES determination in step S17). However, as a predetermined condition (b), after the detection of the person, the predetermined time T2 has elapsed in a situation where the ID information from the electronic key 41 has not been received, and the human sensor 23 has not detected the person after the predetermined time T2 has elapsed. (Proceed to step S18 via the NO determination in step S14 and the YES determination in step S16), or (c) after the detection of the person, the ID information from the electronic key 41 is received, and the person after opening and closing the entrance door 16. When it is satisfied that no person is detected by the motion sensor 23 (YES determination in step S14 and YES determination in step S15 to proceed to step S18), the unlocking disallowance mode is set before the elapse of the predetermined time T1. Will be released.

Next, the control process in locking / unlocking the locking device 21 will be described with reference to FIG.

In step S31, it is determined whether or not the operation signal for locking is received from the electronic key 41. When the lock operation signal is received from the electronic key 41, YES is determined in step S31, and the process proceeds to step S39. If the lock operation signal is not received from the electronic key 41, a NO determination is made and the process proceeds to step S32.

In step S39, the locking device 21 is locked. Here, when the process proceeds from step S31 to step S39, the locking device 21 is locked based on the locking operation signal from the electronic key 41. After locking, this process is completed.

In step S32, it is determined whether or not the unlocking operation signal is received from the electronic key 41. When the unlocking operation signal is received from the electronic key 41, YES is determined in step S32, and the process proceeds to step S38. If the unlocking operation signal is not received from the electronic key 41, a NO determination is made and the process proceeds to step S33.

In step S38, the locking device 21 is unlocked. Here, when the process proceeds from step S32 to step S38, the locking device 21 is unlocked based on the unlocking operation signal from the electronic key 41. After unlocking, this process is terminated.

In step S33, the ID information transmitted from the electronic key 41 as a response to the request signal from the communication device 31 is received through the communication device 31, and it is determined whether or not the result of the authentication process of the ID information is OK. If the authentication is OK, YES is determined in step S33, and the process proceeds to step S34. If the ID information is not received or the authentication is NG, this process is terminated.

In step S34, it is determined whether or not the locking device 21 is in the locked state. If it is in the locked state, a YES determination is made and the process proceeds to step S35. If it is not in the locked state, that is, in the unlocked state, a NO determination is made and the process proceeds to step S37.

In step S37, it is determined whether or not the contact is detected by the doorknob sensor 19 built in the doorknob 18. When the contact is detected by the doorknob sensor 19, a YES determination is made and the process proceeds to step S39. If the contact is not detected by the doorknob sensor 19, a NO determination is made and the present process is terminated.

Here, it is confirmed that the locking device 21 is in the unlocked state by the NO determination in step S34. When the electronic key 41 is authenticated (YES determination in step S33) and the locking device 21 is in the unlocked state (NO determination in step S34), when contact is detected by the doorknob sensor 19, the locking device 21 is locked. (Step S39).

When the process proceeds to step S35 by the YES determination in step S34, it is determined in step S35 whether or not the unlocking disallowed mode is implemented. If the unlocking disallowed mode is not executed, a NO determination is made and the process proceeds to step S36. If the unlocking disallow mode is implemented, a YES determination is made and this process is terminated.

In step S36, it is determined whether or not the contact is detected by the doorknob sensor 19 built in the doorknob 18. When the contact is detected by the doorknob sensor 19, a YES determination is made and the process proceeds to step S38. If the contact is not detected by the doorknob sensor 19, a NO determination is made and the present process is terminated.

Here, it is confirmed that the locking device 21 is in the locked state by the YES determination in step S34. In a situation where the electronic key 41 is authenticated (YES determination in step S33), the locking device 21 is locked (YES determination in step S34), and the unlock disapproval mode is not executed (YES determination in step S35). When the contact is detected by the doorknob sensor 19, the locking device 21 is unlocked (step S38).

As described above, after the unlocking process of the locking device 21 is performed in step S38 or the locking process of the locking device 21 is performed in step S39, this process is terminated.

As can be seen from the fact that the locking device 21 is unlocked from step S32 to step S38, even when the unlocking disallowed mode is implemented, the locking device 21 is remotely operated by the electronic key 41. Can be unlocked. Therefore, if the resident who has returned home cannot unlock the door even if he / she comes into contact with the doorknob 18, he / she can unlock it by pressing the unlock switch 43 of the electronic key 41.

According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

In the present embodiment, when the doorknob 18 on the outdoor side is touched by a resident or the like in a situation where the electronic key 41 is properly authenticated by the ID information, the contact with the doorknob 18 is detected by the doorknob sensor 19, and the locking device is locked. If 21 is in the locked state, it is unlocked, and if it is in the unlocked state, it is locked. Therefore, in the present embodiment, the resident can carry the electronic key 41 and lock / unlock the locking device 21 simply by touching the doorknob 18 on the outdoor side, which is excellent in convenience.

In the present embodiment, when a person is detected near the entrance door 16 on the indoor side by the motion sensor 23, unlocking by contact with the doorknob 18 is not permitted until T1 elapses for a predetermined time after the person is detected. Unlocking disallow mode is implemented. As a result, even if the resident who has returned home stays near the entrance door 16 on the indoor side and the electronic key 41 carried by the resident is properly authenticated, only the contact of the doorknob 18 from the outdoor side is required. The locking device 21 cannot be unlocked. Therefore, it is possible to avoid a situation contrary to the intention of the resident, such as the locking device 21 being unlocked only by a suspicious person or the like coming into contact with the doorknob 18 from the outdoor side, and the crime prevention property is excellent.

In the present embodiment, when the ID information of the electronic key 41 is not received via the communication device 31 in the situation where the unlocking permission mode is implemented, the unlocking is performed after the predetermined time T2 has elapsed before the predetermined time T1 has elapsed. Release the lock disallow mode. As a result, if a resident living together near the entrance door 16 on the indoor side crosses and the resident leaves immediately after being detected by the motion sensor 23, that is, if there is no problem in crime prevention, unlocking is not possible. The execution time of the permission mode can be shortened from the predetermined time T1 to the predetermined time T2. By shortening the execution time of the unlocking disallowed mode when there is no problem in crime prevention, the frequency of encountering the "unlocked disallowed mode" by the resident who has returned home can be reduced, and the convenience can be improved.

In the present embodiment, the detection area DA in which the motion sensor 23 detects a person includes a communication area CA in which the electronic key 41 in the entrance portion 11 (that is, the indoor side of the entrance 15) is authenticated. As a result, when a resident stays near the entrance door 16 on the indoor side, the human sensor 23 does not detect the resident, and the electronic key 41 carried by the resident can be avoided. That is, although the unlocking prohibition mode is not implemented, it is possible to avoid a situation where there is a problem in crime prevention that the unlocking is possible only by touching the doorknob 18.

Communication between the communication device 31 and the electronic key 41 may be delayed for some reason (for example, a plurality of electronic keys are present, or a device that generates radio waves is nearby). According to the present embodiment, after the human sensor 23 detects a person, the reception of the ID information from the electronic key 41 is waited until a predetermined time T2 shorter than the predetermined time T1 elapses. As a result, even if the reception of the ID information from the electronic key 41 is delayed for some reason as described above, the unlocking disallow mode is immediately provided on the condition that the identification information is not received from the electronic key 41. Is not released, so safety can be improved.

Further, in the present embodiment, the detection area DA of the motion sensor 23 includes the communication area CA on the indoor side of the communication device 31 and is widely set. Therefore, for example, when a resident carrying the electronic key 41 stays in a place outside the range of the communication area CA in the detection area DA for a short time and then enters the communication area CA, the person by the motion sensor 23 is used. There may be a time lag between the detection of the above and the communication with the electronic key 41 (reception of the identification information from the electronic key 41). Even in such a case, the unlocking disapproval mode is not immediately released on condition that the identification information is not received from the electronic key 41, so that the security is high.

In the present embodiment, in the situation where the unlocking disallowed mode is implemented, if a person is not detected near the entrance door 16 on the indoor side by the motion sensor 23 after the entrance door 16 is opened and closed, the unlocking is not permitted. Cancel the mode. As a result, for example, when a resident goes out to the outside and immediately notices something left behind and tries to unlock the locking device 21 in order to return to the inside of the building 10, he / she only touches the doorknob 18. The locking device 21 can be unlocked. In such a situation, if there is no person near the entrance door 16 on the indoor side, it is considered that the electronic key 41 does not exist in the communication area CA of the communication device 31 on the indoor side. Therefore, in such a situation, even if the locking device 21 can be unlocked by the contact of the doorknob 18, there is no problem in crime prevention.

Therefore, by canceling the unlocking disallowed mode in the above situation, the convenience can be further improved without impairing the crime prevention property.

In the present embodiment, the locking device 21 has a thumb turn portion 21a on the indoor side that can be manually locked and unlocked. For example, when a resident living together greets a resident who has returned home, an unlocking prohibition mode is executed because a person is detected by the motion sensor 23 at the entrance portion 11, and the resident who has returned home is touched by the doorknob 18. Cannot be unlocked. Even in such a case, according to the present embodiment, the welcoming resident can manually unlock the locking device 21 by operating the thumb turn portion 21a from the indoor side. Therefore, there is no inconvenience for the resident who has returned home, and convenience is ensured without impairing the crime prevention property.

The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

(1) In the above embodiment, when the ID information of the electronic key 41 is not received during the unlocking disallowed mode, the predetermined time T1 for executing the unlocking disallowed mode is shortened to the predetermined time T2. If the ID information of 41 is not received, the unlocking disallowed mode may be canceled immediately.

(2) In the above embodiment, in the vicinity of the entrance door 16 (entrance portion 11) on the indoor side, the detection area DA of the motion sensor 23 is wider than the communication area CA of the communication device 31, but the detection area of the motion sensor 23. The DA and the communication area CA of the communication device 31 may be about the same.

(3) In the above embodiment, the unlocking disapproval mode is canceled on condition that no person is detected after a predetermined time T1 has elapsed from the detection of the person in step S11 (step S18). For example, there may be a case where the detection other than the detection of the person in step S11 is performed between the detection of the person in step S11 and the elapse of the predetermined time T1. Therefore, after the YES determination of "whether or not the predetermined time T1 has elapsed from the detection of the person in step S11" in step S17, the determination of "whether or not the predetermined time T1 has elapsed since the detection of the latest person" is added. You may. If the predetermined time T1 has elapsed from the detection of the latest person, a YES determination is made and the process proceeds to step S18. If T1 has not elapsed since the detection of the latest person, the process returns to step S14, and each process is repeated. As a result, the execution time of the unlocking disallowed mode may be long, but it is excellent from the viewpoint of crime prevention that it covers the detection accuracy of the motion sensor 23.

(4) In the above embodiment, when the electronic key 41 is properly authenticated and the doorknob sensor 19 detects contact with the doorknob 18, the locking device 21 is locked and unlocked. In other words, the detection by the doorknob sensor 19 functions as a lock or unlock switch for the locking device 21, but if the detection can function as a lock or unlock switch for the locking device 21, the doorknob 18, The doorknob sensor 19 is not an essential configuration.

For example, a lock / unlock switch may be provided on the outdoor side surface of the entrance door 16, the outdoor side surface of the wall provided with the entrance door 15, and the like. The switch may be a touch sensor that detects contact, or may be a button that detects that the switch has been operated by pressing. As in the case of the above embodiment, in the situation where the electronic key 41 is normally authenticated, the locking device 21 can be locked / unlocked based on the detection by the switch.

(5) In the above embodiment, the thumb turn portion 21a provided on the locking device 21 can be locked and unlocked from the indoor side by manually operating the thumb turn portion 21a. However, the present invention is not limited to this, and the locking device 21 can be locked and unlocked from the indoor side. It suffices if the operation unit that enables it is provided on the indoor side. For example, a lock / unlock switch as described in (4) above may be provided on the indoor side surface of the entrance door 16 or the indoor side surface of the wall provided with the entrance door 15. As in the case of the above embodiment, even when the unlocking disallow mode is executed because the person is detected by the motion sensor 23, the locking / unlocking device 21 is locked / unlocked based on the detection by the switch. Can be carried out.

(6) In the above embodiment, one locking device 21 is provided on the entrance door 16, but not only the locking device 21 but also a plurality of locking devices may be provided on the entrance door 16. In this case, if the electronic key 41 is properly authenticated, the locking device 21 is unlocked by contacting the doorknob 18 and pressing the locking / unlocking switches 42 and 43 provided on the electronic key 41. In conjunction with the lock, other locking devices provided may be locked and unlocked. Further, the locking device 21 may be linked to the execution and release of the unlocking disallowed mode.

(7) In the above embodiment, the locking / unlocking system of the present invention is applied to the entrance door 16 provided at the entrance 15, but a door (entrance / exit) provided at another entrance / exit such as a door provided at the selfish entrance is used. The locking / unlocking system of the present invention may be applied to the door).

(8) In the above embodiment, when the presence of a person is detected by the motion sensor 23, the unlocking prohibition mode is implemented within a predetermined period after the presence of the person is detected. Here, "when the presence of a person is detected by the motion sensor 23" includes the case where it is considered that the presence of a person is detected by the controller 32. That is, in the unlock disapproval mode, when the condition set as "considering that the presence of a person is detected" is satisfied in the situation where the motion sensor 23 does not detect the presence of a person, the controller 32 Is determined as "when the presence of a person is detected by the motion sensor 23", and the unlocking disapproval mode is implemented.
