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 handle 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, a request signal from the communication device is received. In response to the request signal, the electronic key automatically transmits the identification information unique to the electronic key as an answer signal to the communication device without requiring any operation. Then, on the building side, authentication of whether or not the user is a user (resident) is performed based on the identification information received via the communication device, and the authentication determines that the user is a user, and the user is a door. When the touch sensor detects that the handle is touched, the locking device provided on the door is locked and unlocked. Such a locking / unlocking system is called a smart authentication system because it can be locked / unlocked without picking up an electronic key.

By the way, in such a locking / unlocking system, there is a fraudulent act using a repeater. This fraudulent activity is, for example, when the electronic key is located far from the communication device (locking device), the electronic key is connected to the communication device by a plurality of repeaters to relay radio waves, and communication between these two parties is performed. It is an act to establish. Therefore, the identification information may be collated without the user's knowledge, and the locking device may be unlocked regardless of the user's intention.

Therefore, in order to prevent such fraudulent activity, the smart authentication function is executed (that is, the locking / unlocking operation by smart authentication) by not transmitting the request signal in the predetermined period after locking the locking device by smart authentication. It has been proposed to prohibit (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2012-82253

The technique of Patent Document 1 relates to a locking device provided in a vehicle. Therefore, it is assumed that only one electronic key is carried when using the vehicle. Therefore, for example, a user carrying an electronic key is locked by smart authentication based on his / her own electronic key, and therefore it is easy to understand that execution of the smart authentication function is prohibited after the locking.

On the other hand, in a building such as a house, a plurality of users each carry an electronic key, and when they return home or go out, they lock and unlock with their own electronic key at their own timing. Therefore, as in the above technology, when the execution of the smart authentication function is prohibited for a predetermined period after locking by smart authentication, another user who tries to lock / unlock immediately after locking cannot lock / unlock even if the door handle is touched. In this case, another user knows that the lock / unlock cannot be performed (that is, the execution prohibition period of the smart authentication function) after the lock / unlock by the smart authentication is tried once. After that, the user needs to take out the electronic key from the bag or the like, operate the remote operation switch provided on the electronic key, or wait for a predetermined period until the execution prohibition of the smart authentication function is lifted. However, the convenience will not 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.
The locking device is unlocked based on the smart authentication of the identification information transmitted from the electronic key through the exchange of wireless signals between the communication device and the electronic key in the communication area. Control means to control the lock and
It is a locking / unlocking system equipped with
The control means is
A specific means for identifying which of the plurality of electronic keys the authenticated identification information is, and
When the locking device is locked based on the identification information of the first electronic key specified by the specific means, the unlocking of the second electronic key among the plurality of electronic keys based on the identification information is performed. An invalidation means for invalidating the unlocking of the first electronic key based on the identification information for a predetermined invalidation period without invalidating the first electronic key.
It is characterized by having.

The building locking / unlocking system of the second invention is described in the first invention.
In a situation where the unlocking means is used to invalidate the unlocking of the first electronic key based on the identification information.
Within the communication area, the communication device and the electronic key exchange radio signals with each other.

The fraudulent activity using a repeater in a smart authentication system is often performed when a user carrying an electronic key goes out. For example, by locating a repeater near a user who has gone out (in other words, an electronic key) and causing a communication device to receive identification information transmitted from the electronic key, the locking device can be locked regardless of the user's intention. Can be unlocked. According to the first invention, the lock by smart authentication is the starting point, and then the unlocking by smart authentication with the electronic key is invalidated in a predetermined invalid period. As a result, even if a repeater is used to use the identification information of the electronic key of the user who has gone out, the locking device cannot be unlocked because the unlocking by smart authentication with the electronic key is invalidated. Therefore, it is possible to suppress fraudulent acts using a repeater.

A fraudulent act using a repeater is likely to be performed immediately after the user goes out because the purpose is to invade a house such as a burglary. On the other hand, when the user returns home, such fraudulent acts are unlikely to occur in order to avoid a match-up in the house. According to the first invention, the invalidation of unlocking based on the identification information is executed in a predetermined invalidation period, and is automatically released after the invalidation period has elapsed. From the viewpoint of crime prevention, it is preferable to invalidate the lock by smart authentication immediately after the user goes out. If the user can be unlocked by smart authentication when he / she returns home, it is convenient. Therefore, by providing the invalid period, it is possible to improve the convenience without impairing the crime prevention property.

The invalidation of unlocking by smart authentication performed by the invalidation means is executed for the electronic key (identification information) by specifying the electronic key based on the identification information for which the lock by smart authentication is executed. Then, even when the unlocking by smart authentication is disabled for a specific electronic key, the communication device continues to transmit the request signal, so that the communication device and the electronic key are in the communication area. It is in a state where radio signals can be exchanged within. That is, for example, even in a situation where the unlocking of one user's electronic key is invalidated by smart authentication, another user can perform smart authentication based on the exchange of wireless signals between the communication device and its own electronic key. It can be locked and unlocked by. Since the user carrying the electronic key is invalidated by smart authentication due to the locking / unlocking performed by himself / herself, he / she can know that the invalidation is being executed. Therefore, the invalidation of unlocking by smart authentication can be managed by oneself (the work of trying to unlock by smart authentication is omitted once), and the convenience of other users is maintained. Therefore, according to the first and second inventions, convenience can be improved without impairing crime prevention.

The building locking / unlocking system of the third invention is described in the first or second invention.
The outdoor side near the doorway is equipped with an operation means capable of identifying a plurality of operations.
The control means is characterized in that when a predetermined avoidance operation is performed in the operation means when the locking device is locked, the invalidation by the invalidation means is not executed.

For example, in a situation where the user can determine that he / she is going out in a few minutes (for example, taking out garbage), if the lock is performed by smart authentication, the unlocking is disabled when the user returns home. Can be considered. In such a case, it can be assumed that the user himself / herself is near his / her home and is unlikely to be targeted by a burglary or the like. Therefore, in such a case, disabling the unlocking by smart authentication is an unnecessary situation for crime prevention, and may impair the convenience of the user. According to the third invention, it is possible to select whether or not to invalidate the unlocking by smart authentication at the time of locking by smart authentication. As a result, it is possible to select whether or not to invalidate the unlocking by smart authentication according to the user's own outing business, so that the crime prevention property is not impaired and the convenience is high.

The building locking / unlocking system of the fourth invention is based on any one of the first to third inventions.
The outdoor side near the doorway is equipped with an operation means capable of identifying a plurality of operations.
A plurality of the invalid periods are set, and a predetermined period selection operation is registered corresponding to each of the invalid periods.
The invalid period is determined each time based on the period selection operation by the operating means when the locking device is locked.

For example, when walking from home to the nearest station, fraudulent acts using repeaters are likely to occur on the way to that station. On the other hand, when going out by car from home, it is difficult to cheat using a repeater once the car starts moving. That is, the susceptibility to fraudulent activity using a repeater differs depending on the time spent near the home after going out.

In addition, even if the unlocking is invalidated by smart authentication, if the invalidation period has expired when the user returns home, the unlocking by smart authentication becomes possible, and the smart authentication function The convenience of is utilized.

Therefore, according to the fourth invention, the length of the invalid period can be selected. That is, for each user (electronic key), it is possible to set an invalidation period for invalidating the unlocking by the smart authentication of the user (electronic key) at the time of locking by the smart authentication. As a result, the length of the invalid period can be selected according to one's own convenience (going out time, etc.), and convenience can be improved 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 door handle 17 as a handle on the outdoor side, and the door handle 17 has a built-in touch sensor 18 (see FIG. 1, partially enlarged view of the entrance door 16). The touch sensor 18 is a capacitance type sensor, and detects that a person has come into contact with the sensor portion and the number of such contacts (multi-point contact). The door handle 17 is provided with an indicator light 19 and is used for displaying locking / unlocking information described later.

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 30 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.

The locking device 21 has a built-in locking / unlocking detection sensor 22. The lock / unlock detection sensor 22 is a sensor that detects whether the locking device 21 is in the locked state or the unlocked state.

A communication device 23 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 device 23 includes an LF antenna capable of transmitting radio waves in the LF band and an RF tuner capable of receiving RF radio waves (for example, radio waves in the UHF band) (not shown). The communication device 23 transmits a request signal from the LF antenna to form a communication area CA for wireless communication. The communication area CA in the communication device 23 is a predetermined circular range centered on the communication device 23 in a plan view, and the range is set so as to straddle the indoor side and the outdoor side of the entrance 15. 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 located in the communication area CA. The communication device 23 is capable of bidirectional communication with the electronic key 30 within the communication area CA.

The electronic key 30 is provided with a lock switch 31 for locking and an unlock switch 32 for unlocking as an operation unit. The locking switch 31 for locking and the unlocking switch 32 for unlocking are used for locking and unlocking the locking device 21 by remote operation.

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 41 as a locking / unlocking control means. The controller 41 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 41 is composed of at least a control unit 42 that controls locking / unlocking and display control of locking / unlocking information at the time of locking / unlocking by smart authentication, ID information (identification information) for electronic key authentication, and various sensors. It has a storage unit 43 for storing the detection result and the like, and a timer 44 used for measuring the time.

A communication device 23 is connected to the controller 41. The communication device 23 is capable of wireless communication with the electronic key 30 carried by each resident residing in the building 10. In this case, the controller 41 is capable of wireless communication with the electronic key 30 of each resident via the communication device 23.

The electronic key 30 transmits ID information in response to a request from the controller 41. Here, the communication device 23 transmits the request signal by the LF antenna at a predetermined time cycle (for example, every 0.5 seconds), whereas the electronic key 30 enters the communication area CA of the communication device 23. Receive the request signal. Then, the electronic key 30 transmits the ID information to the communication device 23 in response to the request signal. When the ID information is received by the communication device 23, the ID information is input from the communication device 23 to the controller 41. When the ID information from the electronic key 30 is input via the communication device 23, the controller 41 determines a match between the ID information and the ID information registered in advance in the storage unit 43, and uses the regular electronic key 30 to determine the match. Authenticate whether or not it exists.

The locking device 21 and the touch sensor 18 are connected to the controller 41. The sequential detection result is input to the controller 41 from the touch sensor 18. Then, when the detection result (indicating that a person has touched the touch sensor 18) is input from the touch sensor 18 in the situation where the electronic key 30 is properly authenticated by the above ID information, the controller 41 locks the locking device 21. Or unlock it. That is, when the detection result from the touch sensor 18 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 touch sensor 18. When input, the locking device 21 is locked. Hereinafter, locking and unlocking the locking device 21 by touching the touch sensor 18 based on the authentication of the electronic key 30 is referred to as "locking and unlocking by smart authentication". If the electronic key 30 does not correspond to a legitimate one, the locking device 21 is not locked or unlocked.

An indicator light 19 is connected to the controller 41. The indicator lamp 19 is composed of three-color LEDs of a red LED, a blue LED, and a green LED (not shown), and the lighting method of the three-color LED is controlled by the control unit 42. In the present embodiment, when the locking device 21 is locked / unlocked by smart authentication, the locking / unlocking state (locking state or unlocking state) of the locking device 21 and the type of the unlocking invalidation mode by smart authentication described later are determined. The lock / unlock information shown is identified and displayed.

The controller 41 can also lock and unlock the locking device 21 by receiving an operation signal for locking or unlocking transmitted from the electronic key 30. The electronic key 30 transmits an operation signal for locking or unlocking by pressing each of the switches 31 and 32. At this time, the ID information of the electronic key 30 is also added to the operation signal for locking or unlocking transmitted by the electronic key 30.

When the operation signal from the electronic key 30 is received by the communication device 23, the locking device 21 is locked and unlocked based on the operation signal on condition that the ID information matches. In the present specification, locking / unlocking the locking device 21 based on the operation signal from the electronic key 30 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.

The range in which the operation signal can be transmitted from the electronic key 30 (that is, the range in which the operation signal can be remotely operated) is a predetermined spherical range centered on the electronic key 30, and in the present embodiment, the radius centered on the electronic key 30. It is about 10 m (not shown).

A lock / unlock detection sensor 22 that detects the lock / unlock state of the lock device 21 is connected to the controller 41. The locking / unlocking detection sensor 22 sequentially inputs the detection result to the controller 41. Based on the detection result from the lock / unlock detection sensor 22, the lock / unlock state (locked state or unlocked state) of the locking device 21 is determined.

Next, the contents of the control process executed by the control unit 42 of the controller 41 will be described with reference to the flowcharts of FIGS. 3 to 5.

In the present embodiment, when the locking device 21 is locked by smart authentication, the subsequent unlocking by smart authentication is not permitted for the ID information (hereinafter referred to as authentication ID) authenticated by the smart authentication. You can set the invalidation mode. Specifically, the execution period of the invalidation mode (the period during which the invalidation mode is executed) can be selected by performing a predetermined operation (invalidation operation) at the time of locking by smart authentication. It is also possible not to set the invalidation mode. Even during the execution period of the invalidation mode, the electronic key 30 can be locked and unlocked by remote operation.

There are three invalidation modes:
(A) Invalidation mode 1: Execution period of invalidation mode Predetermined period T1 (for example, 30 minutes);
(B) Invalidation mode 2: Execution period of invalidation mode T2 (for example, 3 hours);
(C) Invalidation mode 3: Execution period of invalidation mode The invalidation mode can be canceled for a predetermined period T3 (for example, 20 hours).

As for the invalidation mode 3, since the execution period of the invalidation mode is long, when a predetermined condition is satisfied, specifically, a predetermined operation (specifically, a predetermined operation is performed in a state where the ID information on which the invalidation is executed is authenticated. The invalidation mode can be canceled by performing the cancel operation).

Hereinafter, the method of executing the invalidation modes 1 to 3 will be described with reference to the flowchart showing the flow of the control process in the locking / unlocking of the locking device 21 by the smart authentication of FIG.

As shown in FIG. 3, in step S11, whether or not the ID information from the electronic key 30 is received via the communication device 23, in other words, whether or not the electronic key 30 is located in the communication area CA. To judge. When the ID information is received, YES is determined in step S11, and the process proceeds to step S12. If the ID information is not received, this process ends.

In step S12, the received ID information is compared with the ID information registered in advance, and authentication is performed as to whether or not the key is a legitimate key. Further, in step S12, the electronic key 30 is specified based on the ID information received by the communication device 23. That is, in this step, when a plurality of electronic keys 30 having different ID information are used, it is specified which of the plurality of electronic keys 30 has entered the communication area CA.

Next, in step S13, it is determined whether or not the result of the authentication process of the ID information in step S12 is OK. If the authentication is OK, a YES determination is made and the process proceeds to step S14. If the authentication is NG, this process is terminated.

In step S14, it is determined whether or not the contact is detected by the touch sensor 18 provided on the door handle 17 in the situation where the ID information is authenticated. When the contact is detected by the touch sensor 18, a YES determination is made and the process proceeds to step S15. If no contact is detected by the touch sensor 18, a NO determination is made and the present process is terminated.

In step S15, the timer 44 is set and the time counting by the timer 44 is started. After the start of timekeeping, the process proceeds to step S16. In the following step S16, it is determined whether or not the detection by the touch sensor 18 is turned off. If the detection by the touch sensor 18 is turned off, a YES determination is made and the process proceeds to step S17. If the detection by the touch sensor 18 is not off, a NO determination is made and the process returns to step S16, and the process of step S16 is repeated until the detection is turned off. Here, the time during which the detection of the touch sensor 18 is turned from on to off is measured by the timekeeping started in step S15. That is, the contact time in the touch sensor 18 is measured.

In step S17, it is determined whether or not the locking device 21 is in the unlocked state based on the detection result from the locking / unlocking detection sensor 22. If the lock is unlocked, a YES determination is made and the process proceeds to step S18. If it is not in the unlocked state, that is, in the locked state, a NO determination is made and the process proceeds to step S21.

In step S21, it is determined whether or not the invalidation mode in the authentication ID is executed. If the invalidation mode is being executed, a YES determination is made and the process proceeds to step S24. If the invalidation mode is not executed, a NO determination is made and the process proceeds to step S22.

Here, when the invalidation mode is executed, the invalidation mode corresponds to the invalidation mode 1 or 2. That is, for the invalidation mode 1 or 2, since the method for canceling the invalidation mode is not set, the locking / unlocking process by smart authentication is completed. On the other hand, when the invalidation mode 3 is executed, a method for canceling the invalidation mode is set. Therefore, when the invalidated authentication ID is received at the time of executing the invalidation mode 3, the processing after step S63 in FIG. 5 to be described later is performed. The details of the processing of each step in this case will be described later, but first, the predetermined release operation of steps S63 to S68 in FIG. 5 is performed, the invalidation mode 3 is canceled in step S69, and the process returns to FIGS. 4 and 3. Then, after the locking / unlocking process by the smart authentication is completed once, the locking / unlocking process of the smart process (FIG. 3, step S11) is started again.

In step S24, the red LED blinks for 3 seconds in the indicator light 19 provided on the door handle 17. The display indicates "the locking device 21 is in the locked state and during the execution period of the invalidation mode". After that, the indicator lamp 19 is turned off, and this process is terminated.

When the present process is terminated by determining YES in step S21, that is, when the invalidation mode is executed, the lock device 21 can be unlocked by remote operation with the electronic key 30. Therefore, if the resident who has returned home cannot unlock the lock even if it comes into contact with the touch sensor 18, the lock can be unlocked by pressing the unlock switch 32 of the electronic key 30.

When the invalidation mode is not executed, the locking device 21 is unlocked in step S22, and in the following step S23, the red LED is turned on for 3 seconds by the indicator lamp 19 provided on the door handle 17. The display indicates "the unlocked state of the locking device 21". After that, the indicator lamp 19 is turned off, and this process is terminated.

If it is determined in step S17 that the lock is in the unlocked state (YES), the locking device 21 is locked in step S18, and the authentication ID is invalidated in the following step S19. The authentication ID invalidation process is a process for determining whether or not to implement the invalidation mode for the authentication ID, and if so, which of the invalidation modes 1 to 3 is to be implemented.

In the authentication ID invalidation process, as shown in FIG. 5, first, in step S31, whether or not the contact operation in the touch sensor 18 was one finger, in other words, whether or not the detection by the touch sensor 18 was one point. Judge whether or not. Here, since the touch sensor 18 can detect multiple points, it can detect the number of fingers that have performed the contact operation (in other words, how many contact points there were). If the contact operation is performed with one finger, a YES determination is made and the process proceeds to step S41. If the contact operation is not one finger, a NO determination is made and the process proceeds to step S32.

In step S41, it is determined whether or not the contact operation on the touch sensor 18 is less than 1 second. Here, if the contact time measured in steps S15 and S16 is less than 1 second, a YES determination is made and the process proceeds to step S46. If the contact time is 1 second or more, a NO determination is made and the process proceeds to step S42.

In step S46, it is determined not to set the authentication ID invalidation process. That is, when the locking by the authentication ID (contact operation in the touch sensor 18) is an operation of one finger and the contact time is less than 1 second, the invalidation mode is not executed. In the following step S47, the blue LED is turned on for 3 seconds by the indicator lamp 19 provided on the door handle 17. The display indicates "locked state, no invalidation mode setting". After that, the indicator lamp 19 is turned off, and the authentication ID invalidation process is completed. After the processing is completed, the process returns to the description of FIG.

On the other hand, if the contact time is 1 second or more, the process proceeds to step S42, and it is determined that the invalidation mode 1 is executed for the authentication ID. That is, the locking by the authentication ID (contact operation in the touch sensor 18) is an operation of one finger, and the contact time is 1 second or more (for example, 2 seconds), so that the invalidation mode 1 is set. In the following step S43, the blue LED blinks for 3 seconds at the indicator light 19 provided on the door handle 17. The display indicates "locked state, execution of invalidation mode 1". After that, the indicator lamp 19 is turned off.

In the following step S44, the timer 44 is set and the time counting by the timer 44 is started. After the start of timekeeping, the process proceeds to step S45. In step S45, it is determined whether or not the predetermined period T1 (30 minutes in this embodiment) has passed since the time counting was started by the timer 44. When the predetermined period T1 has elapsed, the process proceeds to step S37. If the predetermined period T1 has not elapsed, a NO determination is made, the process returns to step S45, and the process is repeated until the predetermined period T1 elapses.

In step S37, the invalidation mode for the authentication ID is turned off. Here, after the invalidation mode 1 is turned on in step S42, the invalidation mode is turned off because the predetermined period T1, which is the execution period of the invalidation mode 1, has elapsed. After turning off the invalidation mode, the authentication ID invalidation process ends.

In step S31, if the touch operation on the touch sensor 18 is not one finger, the process proceeds to step S32. Here, when the contact operation in the touch sensor 18 is not one finger, it means that the touch sensor 18 is operated by two or more fingers (for example, two or three fingers). In step S32, it is determined whether or not the contact operation by two or more fingers on the touch sensor 18 is less than 1 second. Here, if the contact time measured in steps S15 and S16 is less than 1 second, a YES determination is made and the process proceeds to step S33. If the contact time is 1 second or longer, a NO determination is made and the process proceeds to step S51.

In step S33, it is determined to execute the invalidation mode 2 for the authentication ID. That is, the locking by the authentication ID (contact operation in the touch sensor 18) is an operation by two or more fingers, and the contact time is less than 1 second, so that the invalidation mode 2 is set. In the following step S34, the green LED is turned on for 3 seconds by the indicator lamp 19 provided on the door handle 17. The display indicates "locked state, execution of invalidation mode 2". After that, the indicator lamp 19 is turned off.

In the following step S35, the timer 44 is set and the time counting by the timer 44 is started. After the start of timekeeping, the process proceeds to step S36. In step S36, it is determined whether or not the predetermined period T2 (3 hours in the present embodiment) has passed since the time counting was started by the timer 44. When the predetermined period T2 has elapsed, the process proceeds to step S37, and since the predetermined period T2, which is the execution period of the invalidation mode 2, has elapsed, the invalidation mode for the authentication ID is turned off. If the predetermined period T2 has not elapsed, a NO determination is made, the process returns to step S36, and the process is repeated until the predetermined period T2 has elapsed.

In step S32, if the contact operation on the touch sensor 18 is 1 second or longer, the process proceeds to step S51. In step S51, it is determined to execute the invalidation mode 3 for the authentication ID, and the invalidation mode 3 is processed. That is, the locking by the authentication ID (contact operation in the touch sensor 18) is an operation by two or more fingers, and the contact time is 1 second or more, so that the invalidation mode 3 is set.

In the process of the invalidation mode 3, as shown in FIG. 5, first, in step S61, the green LED is blinked for 3 seconds in the indicator lamp 19 provided on the door handle 17. The display indicates "locked state, execution of invalidation mode 3". After that, the indicator lamp 19 is turned off.

In the following step S62, the timer 44 is set and the time counting by the timer 44 is started. Here, the time is set to set A, and after the start of the time of set A, the process proceeds to step S63.

In step S63, whether or not the authentication ID for executing invalidation is received via the communication device 23, in other words, whether or not the electronic key 30 having the authentication ID is located in the communication area CA. Is determined. If the authentication ID for which invalidation is being executed is received, a YES determination is made and the process proceeds to step S64. If the authentication ID executing the invalidation is not received, a NO determination is made and the process proceeds to step S71.

In step S71, it is determined whether or not the predetermined period T3 (20 hours in this embodiment) has passed since the time counting of the set A was started by the timer 44. When the predetermined period T3 has elapsed, the process proceeds to step S72, and since the predetermined period T3, which is the execution period of the invalidation mode 3, has elapsed, the invalidation mode for the authentication ID is turned off. After turning off the invalidation mode, the processing of the invalidation mode 3 is terminated. If the predetermined period T3 has not elapsed, a NO determination is made, the process returns to step S63, and each process is repeated until the predetermined period T3 has elapsed.

When the authentication ID executing the invalidation is received, the process proceeds to step S64, and the contact is detected by the touch sensor 18 provided on the door handle 17 in the situation where the authentication ID executing the invalidation is received. Determine if it has been done. When the contact is detected by the touch sensor 18, a YES determination is made and the process proceeds to step S65. If no contact is detected by the touch sensor 18, a NO determination is made and the process proceeds to step S71.

In step S65, the timer 44 is set and the time counting by the timer 44 is started. Here, the time is set to set B, and after the start of the time of set B, the process proceeds to step S66. In the following step S66, it is determined whether or not the detection by the touch sensor 18 is turned off. If the detection by the touch sensor 18 is turned off, a YES determination is made and the process proceeds to step S67. If the detection by the touch sensor 18 is not off, a NO determination is made and the process returns to step S66, and the process of step S66 is repeated until the detection is turned off. Here, the time during which the detection of the touch sensor 18 is turned from on to off is measured as the contact time by the timekeeping of the set B started in step S65.

In step S67, it is determined whether or not the touch operation on the touch sensor 18 is three or more fingers, in other words, whether or not the detection by the touch sensor 18 is three or more points. If the contact operation is performed with three or more fingers, a YES determination is made and the process proceeds to step S68. If the contact operation is not three or more fingers, a NO determination is made and the process proceeds to step S71.

In step S68, it is determined whether or not the contact operation on the touch sensor 18 is 2 seconds or longer. Here, if the contact time measured in steps S65 and S66 is 2 seconds or more, a YES determination is made and the process proceeds to step S69. If the contact time is less than 2 seconds, a NO determination is made and the process proceeds to step S71.

In step S69, the invalidation mode 3 for the authentication ID is canceled based on the fact that a contact for 2 seconds or more is detected with three or more fingers while receiving the invalidated authentication ID. That is, the invalidation mode 3 is released by making contact with the touch sensor 18 with three or more fingers for two seconds or longer. After canceling the invalidation mode 3, in the subsequent step S70, the blue LED is turned on for 3 seconds by the indicator lamp 19 provided on the door handle 17. The display is the same as "Locked state, no invalidation mode setting", but here it indicates that the invalidation mode has been released. After that, the indicator lamp 19 is turned off, and the processing of the invalidation mode 3 is completed.

Here, each process of steps S63 to S68 is a process of determining whether or not the condition for canceling the invalidation mode 3 is satisfied. If it is determined in steps S63, S64, S67, and S68 that the condition for canceling the invalidation mode 3 is not met (NO determination), the process proceeds to step S71, and each process after S63 is repeated until the elapse of the predetermined period T3. ing.

After the processing of the invalidation mode 3 is completed, the process returns to the description of FIG. 4, and the authentication ID invalidation processing is completed. After the authentication ID invalidation process is completed, the process returns to the description of FIG. 3 and the lock / unlock process by smart authentication is completed.

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

A fraudulent act using a repeater in a smart authentication system is often performed when a resident carrying an electronic key 30 goes out. For example, a repeater may be located near a resident who has gone out (in other words, an electronic key 30) (increase the number of repeaters according to the distance to the building 10 (locking device 21)) from the electronic key 30. By having the communication device 23 receive the transmitted ID information, the locking device 21 can be unlocked regardless of the intention of the resident. According to the present embodiment, the lock is started by smart authentication, and then the unlocking invalidation modes 1 to 3 by smart authentication with the electronic key 30 are executed in a predetermined invalid period. As a result, even if a repeater is used to use the ID information of the resident's electronic key 30 that has gone out, the unlocking device 21 is unlocked because the unlocking by smart authentication with the electronic key 30 is invalidated. Can not. Therefore, it is possible to suppress fraudulent acts using a repeater.

In the present embodiment, the invalidation of unlocking by smart authentication is executed for the electronic key 30 (ID information) by specifying the electronic key 30 based on the ID information for which the lock by smart authentication is executed. Then, even when the unlocking by smart authentication is invalidated for the specific electronic key 30, the communication device 23 continues to transmit the request signal at a predetermined time cycle. That is, since it is possible to exchange wireless signals between the communication device 23 and the electronic key 30 (transmission / reception of the request signal and the ID information) within the communication area, the electronic key 30 located in the communication area is specified based on the ID information. can. Therefore, even in a situation where the electronic key 30 of one resident is executing the unlocking invalidation modes 1 to 3 by smart authentication, the other resident can use the wireless signal between the communication device 23 and his / her own electronic key 30. It is possible to lock and unlock by smart authentication based on the exchange of. The resident carrying the electronic key 30 must know for himself that the invalidation modes 1 to 3 are executed because the invalidation modes 1 to 3 are executed due to the locking / unlocking performed by the resident. Can be done. Therefore, the invalidation of unlocking by smart authentication can be managed by oneself (the work of trying to unlock by smart authentication is omitted once), and the convenience of other residents is maintained. Therefore, according to the present embodiment, convenience can be improved without impairing crime prevention.

For example, in a situation where the resident can determine that he / she is going out in a few minutes (for example, taking out garbage), if the lock is performed by smart authentication, the unlocking is disabled when he / she returns home. Can be considered. In such a case, it can be assumed that the resident himself is in the vicinity of the building 10 and the possibility of being targeted by a burglary or the like is low. Therefore, in such a case, disabling the unlocking by smart authentication is unnecessary for crime prevention and may impair the convenience of the resident. According to the present embodiment, it is possible to select whether or not to set the unlocking invalidation modes 1 to 3 by smart authentication at the time of locking by smart authentication. As a result, it is possible to select whether or not to invalidate the unlocking by smart authentication according to the resident's own outing business, so that the crime prevention property is not impaired and the convenience is high.

For example, when walking from building 10 to the nearest station, fraudulent acts using repeaters are likely to occur on the way to that station. On the other hand, when going out by car from the building 10, if the movement is started by car, it becomes difficult to perform fraudulent acts using the repeater. That is, the susceptibility to fraudulent acts using the repeater differs depending on the time spent in the vicinity of the building 10 after going out.

In addition, even if the unlocking is invalidated by smart authentication, if the invalidation period has expired when the resident returns home, the unlocking by smart authentication becomes possible, and smart authentication is possible. The convenience of the function is utilized.

Therefore, according to the present embodiment, the length of the invalidation period (invalidation modes 1 to 3) can be selected. That is, for each resident (electronic key 30), it is possible to set an execution period (select invalidation modes 1 to 3) for invalidating the unlocking by its own smart authentication when locking by smart authentication. As a result, the length of the invalid period can be selected according to the convenience of the resident (going out time, etc.), and the convenience can be improved without impairing the crime prevention.

In the present embodiment, even in the situation where the unlocking invalidation modes 1 to 3 are executed, the wireless signal is exchanged between the communication device 23 and the electronic key 30, so that the invalidated ID information is received. Is also possible. Therefore, when the invalidated ID information is received, the unlocking by smart authentication can be canceled by performing a predetermined unlocking operation (only in the invalidation mode 3). As a result, for example, even if the user returns home earlier than the invalidation execution period set according to his / her own convenience has elapsed, the unlocking can be performed by smart authentication by performing a predetermined unlocking operation. As a result, it is possible to improve the crime prevention by setting a long invalidation execution period, and to cancel the invalidation when returning home before the invalidation execution period elapses, which is excellent in convenience.

According to the present embodiment, when locking / unlocking is performed by smart authentication, the locked / unlocked state of the locking device 21 and the presence / absence of the invalidation modes 1 to 3 are identified by the color of the indicator lamp 19 and the lighting method. Is displayed. This makes it possible to confirm the locking / unlocking operation of the locking device 21 and the setting of the invalidation modes 1 to 3 performed by the resident himself / herself.

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 invalidation mode 3 is executed, after the invalidation mode 3 is canceled by a predetermined cancellation operation (corresponding to steps S63 to S68 in FIG. 5), smart authentication is performed again. Although the locking / unlocking process (FIG. 3, step S11) is started, it may be set so that the locking / unlocking operation of the locking device 21 can be executed at the same time by the unlocking operation of the invalidation mode. In this case, in the situation where the invalidated ID information is received, the locking device 21 is unlocked by determining that the operation of the unlocking operation of the invalidation mode 3 is a regular operation. Since unlocking is disabled by smart authentication, the locking device 21 is not unlocked by normal operation (generally assumed to be a contact operation of less than 1 second with one finger), but it is disabled. Since the locking device 21 is unlocked by a single operation for unlocking, the security is high and the convenience is also excellent.

(2) In the above embodiment, the release operation is set only in the invalidation mode 3, and the invalidation modes 1 and 2 require the elapse of the set predetermined period T1 and T2. The release operation may be set in the mode. In this case, the release operation corresponding to each of the invalidation modes 1 to 3 may be set, or one specific operation may be set as the release operation.

(3) In the above embodiment, the locking device 21 is locked and unlocked when the contact with the touch sensor 18 provided on the door handle 17 is detected in the situation where the electronic key 30 is properly authenticated. In other words, the detection by the touch sensor 18 functions as a lock / unlock switch and an invalidation setting switch of the locking device 21, but can also function as a locking / unlocking switch of the locking device 21. If so, the door handle 17 and the touch sensor 18 are not essential configurations.

For example, instead of the touch sensor 18, a lock / unlock button may be provided, and the lock / unlock switch may be used by detecting that the lock / unlock button is pressed. Then, the operation for setting and releasing the invalidation mode in this case can be set separately according to the pressing time of the pressing operation by the lock / unlock button and the like.

Further, the touch sensor 18 may be provided on the outdoor side surface of the entrance door 16, the outdoor side surface of the wall provided with the entrance entrance 15, and the like.

(5) In the above embodiment, the operation for setting and canceling the invalidation mode is set based on the number of fingers detected by the touch sensor 18 and the contact time, but if each operation can be distinguished. Well, I'm not limited to this. For example, as an operation in the touch sensor 18, the touch sensor 18 may be divided into a plurality of parts, and how many of the divided parts are touched may be detected (contact range detection; for example, detection by a three-part touch sensor). .. Further, the touch sensor 18 can detect the swipe operation, distinguishing between the simple touch operation and the swipe operation, and detecting the number of fingers of the swipe operation, the direction of the swipe operation (for example, from right to left, etc.). May be good. By detecting such an operation in the touch sensor 18, a large number of operations can be distinguished, and invalidation modes of various conditions can be set.

(6) In the above embodiment, in the locking / unlocking by smart authentication, the lock / unlock information (locking / unlocking state and whether or not the invalidation modes 1 to 3 are set) is displayed by the indicator lamp 19, but the display by the indicator lamp 19 is indispensable. It is not the composition of.
