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

  As shown in FIG. 1, in the building 10, an entrance 11, a corridor 12, a living room 13 and the like are provided as indoor spaces. The entrance 11 is provided with an entrance 15 as an entrance. Access to the building 10 is possible through the entrance 15. The entrance door 15 is provided with an entrance door 16 as an entrance door. The entrance door 16 is, for example, a pivoting open door. The entrance 15 is opened and closed by the entrance door 16. Moreover, the door knob 17 as a handle is provided in the entrance side door 16 by the indoor side and the outdoor side, respectively. The entrance door 16 may be a sliding door.

  The entrance door 16 is provided with a locking device 18. The locking device 18 is a device that performs locking and unlocking (locking and unlocking) of the entrance door 16 by electrically locking and unlocking the lock. The locking device 18 is locked and unlocked by an electronic key 20 owned by a resident of the building 10. In addition, the locking device 18 has a thumb turn 18 a that can be locked and operated from the indoor side (the entrance 11 side), and locking is also possible by the operation of the thumb turn 18 a.

  In the building 10, a communication device 19 capable of wireless communication with the electronic key 20 is provided. The communication device 19 is provided, for example, on an outer wall near the entrance door 16. The communication area of the communication device 19 is set to a predetermined range that spans the indoor side and the outdoor side of the entrance 15. Communication with the electronic key 20 is enabled in the communication area. Specifically, in the communication area of the communication device 19, the resident holds the door knob 17 indoors of the entrance door 16, and the resident holds the door knob 17 outdoors of the entrance door 16. It is set to be located in the communication area.

  Subsequently, a locking and unlocking system for locking and unlocking the locking device 18 will be described.

  The locking and unlocking system includes a plurality of sensors 21 to 23 around the entrance door 16. The open / close detection sensor 21 among the sensors 21 to 23 is a sensor that detects the open / close state of the front door 16. The open / close detection sensor 21 is provided, for example, on the indoor side of the entrance door 16. The locking / unlocking detection sensor 22 is a sensor that detects whether the locking device 18 is in the locked state or in the unlocked state. The locking and unlocking detection sensor 22 is incorporated, for example, in the locking device 18.

  The doorknob sensor 23 is a touch sensor that detects that a person has made contact with the doorknob 17. The doorknob sensor 23 is incorporated in the doorknob 17, for example. The doorknob sensor 23 is provided in each of the indoor side doorknob 17a and the outdoor side doorknob 17b. In the following, a is attached to the sign of the doorknob sensor 23 provided on the doorknob 17a on the indoor side, and b is attached to the sign of the doorknob sensor 23 provided on the doorknob 17b on the outdoor side. The doorknob sensors 23a and 23b correspond to handle detection means.

  Subsequently, the electrical configuration of the locking and unlocking system will be described based on FIG. FIG. 2 is a diagram showing an electrical configuration of the locking and unlocking system.

  As shown in FIG. 2, the locking and unlocking system includes a controller 25 as an unlocking control means. The controller 25 is configured to include a known microcomputer having a CPU and the like, and is provided, for example, on the wall surface of the entrance 11.

  A communication device 19 is connected to the controller 25. The communication device 19 can wirelessly communicate with the electronic key 20 carried by each resident in the building 10. In this case, the controller 25 can wirelessly communicate with the electronic key 20 of each resident through the communication device 19.

  Each electronic key 20 stores ID information as identification information. The ID information is information unique to the electronic key 20 in which the information is stored, and thus is information unique to the resident who holds the electronic key 20. Therefore, it is possible to identify each resident (the electronic key 20) by the ID information. On the other hand, the controller 25 has an ID information storage unit 26 for storing ID information of each electronic key 20. Each ID information stored in the ID information storage unit 26 corresponds to the ID information stored in each electronic key 20.

  The controller 25 transmits a request signal to the communication area described above through the communication device 19 at predetermined intervals (for example, every 0.5 seconds). The request signal is a signal for requesting the electronic key 20 to transmit ID information. When the resident carrying the electronic key 20 enters the communication area, the electronic key 20 receives a request signal. Then, the electronic key 20 transmits ID information as a response to the request signal. Then, when the ID information is received by the communication device 19, the ID information is input from the communication device 19 to the controller 25.

  The controller 25 controls each door knob sensor 23a. 23b is connected. The controller 25 receives detection results sequentially from the doorknob sensors 23a and 23b. The controller 25 is received through the communication device 19 when a detection result (indicating that a person contacts the doorknob 17) is input from any of the doorknob sensors 23a and 23b in a state where the locking device 18 is locked. An authentication process is performed based on the ID information from the electronic key 20. In the authentication process, the controller 25 authenticates (determines) whether or not the ID information received from the electronic key 20 matches the ID information stored in the ID information storage unit 26. Specifically, it is verified whether the received ID information matches any one of the pieces of ID information stored in the ID information storage unit 26.

  A locking device 18 is connected to the controller 25. The controller 25 outputs an unlocking signal to the locking device 18 based on the authentication result of the ID information, and unlocks the locking device 18. That is, when the ID information from the electronic key 20 matches the ID information stored in the ID information storage unit 26 as a result of the authentication processing, that is, the controller 25 unlocks the locking device 18 in the case of authentication OK. If the ID information from the electronic key 20 does not match the ID information stored in the ID information storage unit 26, that is, in the case of authentication NG, the locking device 18 is kept in the locked state.

  As described above, in this locking / unlocking system, when any of the doorknob 17a on the indoor side and the doorknob 17a on the outdoor side is touched (touched) by the resident or the like in the locked state of the locking device 18, the doorknob 17 A contact to the touch is detected by the corresponding doorknob sensor 23a (23b), and based on the detection, authentication processing of ID information received from the electronic key 20 is performed. Then, as a result of the authentication, when the authentication is OK, the locking device 18 is unlocked. Therefore, in this locking and unlocking system, when the resident returns home, it is possible to unlock the locking device 18 simply by touching the doorknob 17b on the outdoor side. Also, when the resident goes out, it is possible to unlock the locking device 18 simply by touching the doorknob 17a on the indoor side.

  Further, the controller 25 is received through the communication device 19 when a detection result (indicating that a person has made contact with the doorknob 17b) is input from the doorknob sensor 23b on the outdoor side in a state where the locking device 18 is unlocked. An authentication process is performed based on the ID information from the electronic key 20. Then, the controller 25 outputs a locking signal to the locking device 18 based on the result of the authentication process, and controls the locking device 18 to lock. That is, as a result of the authentication process, the controller 25 locks the locking device 18 in the case of the authentication OK, and keeps the locking device 18 in the unlocked state in the case of the authentication NG.

  Therefore, in the locking / unlocking system, when the doorknob 17b on the outdoor side is touched (touched) by the resident or the like in the unlocked state of the locking device 18, contact with the doorknob 17b is detected by the doorknob sensor 23b, An authentication process of the ID information received from the electronic key 20 is performed based on the detection. Therefore, in this locking and unlocking system, when the resident locks the locking device 18 when the resident goes out, the resident can lock only by touching the doorknob 17b on the outdoor side.

  Further, in the present locking and unlocking system, when the resident returns home, the resident locks the thumb turn 18a of the locking device 18 indoors in order to lock the locking device 18 when the resident returns home.

  Here, in the present locking and unlocking system, in addition to the locking and unlocking of the locking device 18 described above, at-home management is performed to manage whether or not each resident is at home in the building 10. So, below, the composition about the at-home management is explained.

  When the controller 25 unlocks the locking device 18 based on the authentication process of the ID information received from the electronic key 20, the resident is determined by which detection of the door knob sensor 23a or 23b is performed. To determine whether to go out or go home. In this outing home determination processing, that is, when the resident unlocks the locking device 18, it is determined whether the resident goes out or goes home depending on which doorknob 17 of the doorknobs 17a and 17b is touched by the resident. Do.

  The controller 25 performs resident identification processing for identifying who is the resident who goes home or goes out, in addition to the above-mentioned return home determination processing. The resident identification process is performed based on the ID information received from the electronic key 20 through the communication device 19.

  The controller 25 has a home information storage unit 27 that stores home information on whether the resident is at home. The at-home information storage unit 27 stores at-home information of each resident. The at-home information storage unit 27 corresponds to a storage unit.

  The controller 25 performs at-home information update processing for updating the at-home information stored in the at-home information storage unit 27 for the resident identified by the resident identification processing based on the determination result of the leaving-home determination processing. In this update process, when it is determined that the resident goes out by the return-home determination process, the at-home information stored in the at-home information storage unit 27 is updated to the information indicating the absence. On the other hand, when it is determined that the resident returns home by the return-home determination processing, the home information stored in the home information storage unit 27 is updated to the information indicating that the home is at home.

  The controller 25 is connected to an open / close detection sensor 21 and a locking / unlocking detection sensor 22. Detection results are sequentially input from the sensors 21 and 22 to the controller 25. The controller 25 updates the at-home information stored in the at-home information storage unit 27 based on the detection results from the sensors 21 and 22.

  Next, control processing executed by the controller 25 will be described based on the flowchart shown in FIG. Note that this process is repeatedly performed in a predetermined cycle.

  As shown in FIG. 3, first, in step S11, door unlocking processing is performed. Therefore, the door unlocking process will be described based on the flowchart shown in FIG. At the start of the door unlocking process, the locking device 18 is in the locked state.

  As shown in FIG. 4, in the door unlocking process, first in step S31, based on the detection results from the doorknob sensors 23a and 23b, a person (for example, a resident) has touched one of the doorknobs 17a and 17b. Determine if If one of the doorknobs 17a and 17b is touched by a person, the process proceeds to step S32. If any one of the doorknobs 17a and 17b is not touched, the present process is terminated.

  In step S32, it is determined whether the ID information transmitted from the electronic key 20 as a response to the request signal from the communication device 19 has been received through the communication device 19. Specifically, in this step, it is repeatedly determined whether or not ID information has been received from the electronic key 20 for a predetermined time (for example, about 5 seconds), and ID information is received from the electronic key 20 within the predetermined time It is determined whether or not. If the ID information has not been received from the electronic key 20, the present process ends, and if the ID information has been received from the electronic key 20, the process proceeds to step S33.

  In step S33, authentication processing of the ID information received from the electronic key 20 is performed. In the authentication process, as described above, authentication (determination) is performed as to whether or not the received ID information matches (any of) ID information stored in the ID information storage unit 26. As a result of the authentication process, if the ID information received from the electronic key 20 matches any ID information stored in the ID information storage unit 26, that is, if the authentication is OK, the step S34 is positively determined, and the step S35 is performed. Go to On the other hand, when the ID information received from the electronic key 20 does not match any of the ID information stored in the ID information storage unit 26, that is, in the case of the authentication NG, the present process is ended.

  In step S35, the locking device 18 is unlocked by outputting an unlocking signal to the locking device 18. Thus, the resident can open the front door 16 and go home or go out of the building 10. Thereafter, the process ends.

  Returning to the explanation of FIG. 3, after the door unlocking process (step S11), the process proceeds to step S12, and it is determined whether or not the locking device 18 is unlocked in the unlocking process. That is, here, it is determined whether or not the process of step S35 in the door unlocking process, that is, the unlocking process of the locking device 18 has been performed. When the unlocking process of the locking device 18 is not performed, that is, when the locking device 18 is in the locked state, the present process is ended. On the other hand, when the locking device 18 is unlocked, the process proceeds to step S13.

  In step S13, the process of determining whether the resident goes out or goes home is performed (corresponding to a means for determining going out of home). In this determination process, it is determined whether the resident goes out or returns home based on which doorknob 17 of the doorknobs 17a and 17b is touched by a person (that is, the resident) in step S31 of the door unlocking process (FIG. 4) Do. In other words, it is determined whether the resident goes out or goes home depending on which of the doorknob sensors 23a and 23b has detected contact with the doorknob 17 in step S31. Specifically, in this step, when the resident touches the doorknob 17a on the indoor side among the doorknobs 17a and 17b, it is determined that the resident goes out, and the resident touches the doorknob 17b on the outdoor side In this case, it is determined that the resident will come home.

  In the subsequent step S14, resident identification processing is performed to identify who is the resident who goes out or comes home. Hereinafter, this resident identification processing will be described based on the flowchart shown in FIG.

  As shown in FIG. 5, in the resident identification process, an unlocking timer is first set in step S41. The unlocking timer measures an elapsed time after the locking device 18 is unlocked. In the following step S42, it is determined whether the elapsed time measured by the unlocking timer has exceeded a predetermined time. That is, here, it is determined whether or not a predetermined time has elapsed since the locking device 18 was unlocked. The predetermined time is set to, for example, about 15 seconds, sufficiently longer than the time required for the resident to open the front door 16 after the locking device 18 is unlocked.

  If the predetermined time has not elapsed since the locking device 18 was unlocked, the process proceeds to step S43, and the entrance door 16 is opened (opened) based on the detection result from the open / close detection sensor 21. It is judged whether it is (it corresponds to a door open judging means). If the front door 16 is open, the process proceeds to step S44. In this case, it can be determined that the resident is going to go home or go out through the entrance 15.

  On the other hand, if the front door 16 is closed (closed), the process returns to step S42, and the processes of step S42 and step S43 are repeated until the predetermined time has elapsed. Then, when the predetermined time has elapsed, the present process ends. In this case, it can be considered that the resident opened the front door 16 and did not go out or go home even though the locking device 18 was unlocked.

  In step S44, it is determined whether the ID information transmitted from the electronic key 20 as a response to the request signal from the communication device 19 has been received. That is, it is determined here whether or not the entrance door 16 is opened and the ID information transmitted from the electronic key 20 of the resident who goes out or goes home from the entrance 15 has been received. When the ID information is received from the electronic key 20, the process proceeds to step S45, and when the ID information is not received from the electronic key 20, the process proceeds to step S46.

  In step S45, resident identification processing is performed to identify who is the resident who goes out or returns home based on the ID information received from the electronic key 20 (corresponding to a resident identification means).

  In step S46, based on the detection result from the open / close detection sensor 21, it is determined whether the front door 16 is closed (closed). If the front door 16 has been closed, the process proceeds to step S47, and a door open / close flag indicating that the front door 16 has been opened (operated) is set. Thereafter, the process ends.

  On the other hand, when the front door 16 is not closed yet, the process returns to step S44, and the processes of step S44 and step S45 are performed again. That is, here, the processes in steps S44 and S45 are repeatedly performed until the front door 16 is closed, in other words, while the front door 16 is opened.

  Here, when a resident goes out or comes home, it is considered that a plurality of residents (for example, all family members) may go home or go out together. In this case, it is considered that while the front door 16 is opened, each resident will go home or go out (into and out of the building 10) sequentially through the front door 15. In such a case, an ID signal transmitted from the electronic key 20 of each resident returning home or going out through the entrance 15 is received each time (YES in step S44), and each resident is identified based on the received ID information. (Step S45). Therefore, when a plurality of residents go out or go home, the process of steps S44 and S45 is repeated to identify who each resident is.

  Referring back to FIG. 3 again, after the resident identification process (step S14), the process proceeds to step S15 to perform at-home information update process. In the at-home information update process, the at-home information of the resident stored in the at-home information storage unit 27 is updated based on the determination result of the return-home determination process. Hereinafter, the at-home information update process will be described based on the flowchart shown in FIG.

  As shown in FIG. 6, in the at-home information update process, it is first determined in step S51 whether the door open / close flag is set. If the door opening / closing flag is not set, the process proceeds to step S63, and a locking signal is output to the locking device 18 to lock the locking device 18. Thereby, even if the locking device 18 is unlocked, the locking device 18 is automatically locked when the resident does not go out or return home. Thereafter, the process ends.

  If the door open / close flag is set, the process proceeds to step S52, and the door close timer is set. The door closing timer measures an elapsed time after the front door 16 is closed. In the following step S53, it is determined whether the elapsed time measured by the door closing timer has exceeded a predetermined time. That is, here, it is determined whether or not a predetermined time has elapsed since the front door 16 is closed. The predetermined time is set to, for example, about 15 seconds, sufficiently longer than the time required for the resident to lock (lock operation) the locking device 18 after the entrance door 16 is closed.

  If the predetermined time has not elapsed since the entrance door 16 is closed, the process proceeds to step S54, and it is determined whether the resident has touched the outdoor doorknob 17b based on the detection result from the doorknob sensor 23b. That is, it is determined whether the resident has touched the doorknob 17b in order to lock the locking device 18. In other words, it is determined whether the resident has performed the locking operation on the locking device 18 from the outdoor side.

  If the resident touches the doorknob 17b on the outdoor side, the process proceeds to step S58, and it is determined whether the ID information transmitted from the electronic key 20 has been received as a response to the request signal transmitted from the communication device 19. Specifically, in this step, it is repeatedly determined whether or not the ID information has been received from the electronic key 20 for a predetermined time, and it is determined whether the ID information has been received from the electronic key 20 within the predetermined time. The predetermined time is set to, for example, about 5 minutes.

  If the ID information has not been received from the electronic key 20, this processing ends. On the other hand, when the ID information is received from the electronic key 20, the process proceeds to step S59, and authentication processing of the ID information is performed. Since this authentication process is the same process as the authentication process (step S33) in the door unlocking process (FIG. 4) described above, the description thereof is omitted here.

  As a result of the authentication process of the ID information, if the authentication is NG, the negative determination is made in step S60, and the present process is ended. On the other hand, if the authentication is OK, an affirmative determination is made in step S60, and the process proceeds to step S61. In step S61, the locking device 18 is locked by outputting a locking signal to the locking device 18. Thereafter, the process proceeds to step S62.

  When the resident does not touch the doorknob 17b on the outdoor side in the previous step S54, the process proceeds to step S55. In step S55, based on the detection result from the locking / unlocking detection sensor 22, it is determined whether or not the locking device 18 is switched from the unlocked state to the locked state, that is, the resident performs the locking operation of the locking device 18 by the thumb turn 18a. Determine if In other words, it is determined whether the resident has performed the locking operation on the locking device 18 from the indoor side. When the resident performs a locking operation by the thumb turn 18a and the locking device 18 is locked, the process proceeds to step S56.

  On the other hand, when the resident does not perform the locking operation by the thumb turn 18a, the process returns to step S53, and the processes of steps S53 to S55 are repeated until the predetermined time (step S53) elapses. When the predetermined time has elapsed, the process proceeds to step S63, where the locking device 18 is locked. Thus, even if the entrance door 16 is closed, the locking device 18 is automatically locked when the locking device 18 is not operated by the resident.

  In addition, "locking operation determination means for determining whether the locking device 18 is operated from the indoor side or the outdoor side" is configured by each process of step S54 and step S55.

  Subsequently, each process of step S62 and step S56 will be described. First, the process in step S62 will be described. When proceeding to step S62, the resident performs the locking operation of the locking device 18 from the outdoor side (YES determination in step S54), and the locking device 18 is locked thereby ( Step S61). Then, in step S62, it is determined whether or not it is determined that the resident goes out in the above-described step-out home determination process (step S13). In the return home determination process, when it is not determined that the resident goes out (that is, when it is determined that the resident returns home), the process ends. On the other hand, if it is determined that the resident goes out, the process proceeds to step S57. That is, when it is determined that the resident goes out and the locking operation of the locking device 18 is performed from the outdoor side, the process proceeds to step S57.

  Next, the process of step S56 will be described. When proceeding to step S56, the resident performs the locking operation of the locking device 18 by the thumb turn 18a from the indoor side (YES judgment in step S55), whereby the locking device 18 It is a case where it is locked. Then, in step S56, it is determined whether or not it is determined that the resident is going home in the above-described going-out home determination process (step S13). When it is determined in the return-home determination process that the resident does not go home (that is, when it is determined that the resident goes out), the process ends. On the other hand, if it is determined that the resident returns home, the process proceeds to step S57. That is, when it is determined that the resident returns home and the locking operation of the locking device 18 is performed from the indoor side, the process proceeds to step S57.

  In step S57, at-home information update processing is performed (corresponding to at-home information update means). In this update process, the at-home information stored in the at-home information storage unit 27 is updated for the resident identified by the resident identification process (step S14) based on the result of the return-home determination process (step S13). For example, when a plurality of residents are identified by the resident identification process, the home information of each resident is updated. Thereafter, the process ends.

  Here, in the present building 10, on the basis of the at-home information of each resident stored in the at-home information storage unit 27, for example, alert control for performing alerting of the building 10 is executed. To briefly explain the alert control, whether the controller 25 is in an absent state where no resident in the building 10 is at home based on the home information of each resident stored in the home information storage unit 27 The absence determination process is performed to determine the condition, and when it is determined that the inside of the building 10 is in the absence state by the absence determination process, predetermined alert control is performed.

  Specifically, the building 10 is provided with an intrusion detection sensor for detecting that a suspicious person has invaded the building 10 as a warning system, and an alarm unit for giving an alarm to the intruding suspicious person. It is done. Then, the controller 25 executes, as the above-mentioned alert control, control of emitting an alarm to the suspicious person from the alarm unit when the intrusion detection sensor detects the suspicious person. In this case, when the inside of the building 10 is absent, the alert control is automatically executed, so that the convenience can be improved in alerting the building 10.

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

  When the contact with the doorknob 17 is detected by any of the doorknob sensors 23a and 23b provided on the doorknobs 17a and 17b of the entrance door 16, the locking device 18 is based on the ID information received from the electronic key 20 carried by the resident. To unlock the As a result, when the resident goes out or goes home, the locking device 18 is unlocked when the resident touches the door knobs 17a and 17b, so convenience is improved in unlocking both when going out and when going home Can be

  Further, based on which of the doorknob sensors 23a and 23b detects a touch on the doorknobs 17a and 17b, in other words, the resident goes out based on which doorknob 17 of the doorknobs 17a and 17b is touched by a person. It was decided whether to go or to go home. Specifically, when the contact to the doorknob 17a on the indoor side is detected, it is determined that the resident goes out, and when the contact to the doorknob 17b on the outdoor side is detected, it is determined that the resident returns home. In this case, by determining whether the resident leaves home, it is possible to grasp whether the resident is at home in the building, so it is possible to preferably perform home management of the resident using the locking and unlocking system. It becomes.

  In the configuration in which each resident living in the building 10 possesses the electronic key 20 for transmitting ID information unique to the resident, and based on the ID information received from the electronic key 20, it is specified who the resident who goes out or returns home is I did it. In addition, for the specified resident, based on the determination result of the leaving-home determination unit, the at-home information (information on whether or not the resident is at home) stored in the at-home information storage unit 27 is updated. Thereby, it becomes possible to preferably perform at-home management of each resident who lives in the building 10.

  After the locking device 18 is unlocked, it is determined whether or not the front door 16 is opened (step S43), and the ID information received from the electronic key 20 while it is determined that the front door 16 is open Based on that the resident who went out or returned home was identified. In this case, when a plurality of residents (for example, family members) go home or go out together, when the respective residents open the front door 16 and go out or go home (that is, go into or out of the building 10), Each resident can be identified based on the ID information received from the key 20. Thereby, when a plurality of residents go out or go home, it becomes possible to respectively identify each of the residents.

  After the locking device 18 is unlocked, the resident may open and close the front door 16 to go home or go home. Therefore, in the above embodiment, when the front door 16 is opened and closed (operated) after the locking device 18 is unlocked, a door open / close flag indicating that the front door 16 has been opened and closed is set (step S47) The resident's at-home information is updated on the condition that the door open / close flag is set (when YES is determined in step S51). In this case, since the at-home information is updated when the resident actually goes home or goes out, highly accurate at-home management can be performed.

  After the locking device 18 is unlocked, the resident may open the front door 16 and return home or go out, and then shut the front door 16 to lock (operate) the locking device 18. So, in said embodiment, when the said locking apparatus 18 was locked after the unlocking of the locking apparatus 18 (when it is judged as YES by step S54 or S55), it was made to update a resident's at-home information. Also in this case, since the resident's at-home information is updated when the resident returns home or goes out, highly accurate home management can be performed.

  Specifically, when it is determined that the resident goes out in the return-home determination process (step S13) (YES determination in step S62), the lock operation is performed from the outdoor side (YES in step S54) If it is determined that the home information is updated and it is determined that the resident returns home (YES in step S56), YES is determined in step S55 on the condition that the locking operation is performed from the indoor side (YES in step S55). Updated the at-home information). As a result, since the home information is updated when the resident surely comes home or goes out, more accurate home management can be performed.

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

  (1) In the above embodiment, the resident who goes out or comes home is specified based on the ID information received from the electronic key 20 while the front door 16 is opened, but this may be changed, for example, the locking device 18 The resident who goes out or goes home may be specified based on the ID information received from the electronic key 20 until the predetermined time elapses after the key is unlocked. Also in this case, after the locking device 18 is unlocked, it is possible to preferably identify each resident who goes out or comes home after opening the entrance door 16.

  In addition, when authenticating the ID information, the resident who goes out or comes home may be specified based on the ID information (step S32) received from the electronic key 20. However, in this case, only the resident who unlocks is identified as the resident who goes out or comes home, and therefore, when a plurality of residents go out or go home, it is impossible to specify each of the respective residents. . Therefore, in view of the point, it is desirable to identify the resident who goes out or returns home based on the ID information received from the electronic key 20 while the front door 16 is opened as in the above embodiment.

  (2) In the above embodiment, when it is determined that the resident goes out, the resident at home stored in the home information storage unit 27 is conditioned on the locking operation of the locking device 18 from the outdoor side. If it is determined that the resident will return home after updating the information, the resident's home information is updated on the condition that the locking device 18 has been locked from the indoor side. May be For example, regardless of the locking operation from the outdoor side and the locking operation from the indoor side, when the locking operation is performed on the locking device 18 (that is, when YES is determined in either step S54 or S55) ), Home information may be updated uniformly. Also in this case, since the at-home information is updated after the locking of the locking device 18, the at-home information of the resident is updated when the resident returns home or goes out. Therefore, highly accurate home management can be performed.

  When the front door 16 is opened and closed (operated) (when YES is determined in step S51), the at-home information is uniformly updated regardless of the presence or absence of the locking operation on the locking device 18. Good. Also in this case, since the at-home information is updated when the resident actually opens the front door 16 and goes home or goes out, highly accurate home management can be performed.

  (3) In the above embodiment, the door knob sensor 23 for detecting that a person has touched the doorknob 17 is provided as the handle detection means, but instead, the person is in the opening direction for the doorknob 17 as the handle detection means. A sensor that detects that the user has made a rotational operation, a sensor that detects that a person has pressed the door knob 17, or the like may be provided. In this case, when the resident unlocks the locking device 18, the door knob 17 is rotated or pushed. Even in the case where such a sensor is provided, by providing the sensors on the doorknobs 17a and 17b on the indoor side and the outdoor side, as in the case of the above embodiment, it depends on which of the sensors on the indoor side and the outdoor side was detected. It can be determined whether the resident goes out or comes home (going out home determination processing).

  The doorknob sensor 23a (contact sensor) in the above embodiment is provided in the doorknob 17a on the indoor side, and the doorknob 17b on the outdoor side is provided with the above-described sensor for detecting a rotation operation or a pressing operation on the knob 17b. The sensors provided at 17a and 17b may be different.

  (4) In the above embodiment, the handle of the entrance door 16 is the door knob 17. However, as the handle of the entrance door 16, various things such as a lever type and a bar type extending vertically can be used besides the knob. There is. Therefore, the present invention may be applied to an entrance door having a handle other than such a knob. Also in such a case, a contact sensor or the like for detecting contact with the handle may be provided as the handle detection means with respect to the handle.

  (5) In the above embodiment, the alert control of the building 10 is executed based on the at-home information of each resident stored in the at-home information storage unit 27. However, instead of or in addition to this, for example, at-home At-home information of each resident stored in the information storage unit 27 may be notified (sent) to a portable terminal (such as a mobile phone or a smartphone) carried by the resident. For example, when the controller 25 receives a request from a portable terminal or a predetermined predetermined time comes, the at-home information of each resident stored in the at-home information storage unit 27 is read, and the read at-home information is read through the communication device 19 It is conceivable to transmit to the mobile terminal of the resident. In this case, the resident carrying the portable terminal can grasp the at-home situation of the other resident even from outside.

  In addition, the determination result of the going-out home determination process (step S13) (that is, going-out home information related to whether the resident goes out or goes home) may be transmitted as it is to the mobile terminal of the resident. In this case, it may be considered to transmit, to the portable terminal, the out-of-home return information of each resident identified by the resident identification process (step S14). In that case, since the resident carrying the portable terminal can grasp sequentially whether another resident went out or returned home from outside, he can grasp the home condition of the other resident in the same manner as described above.

  (6) In the above embodiment, when the resident returns home, the locking device 18 is locked by locking the thumb-turn 18a indoors, but instead or in addition to this, The locking device 18 may be locked when the resident touches the doorknob 17a on the indoor side. That is, when the doorknob 17a on the indoor side is touched by the resident in the unlocked state of the locking device 18, contact with the doorknob 17a is detected by the doorknob sensor 23a, and the ID information received from the electronic key 20 is detected based on the detection. Enable authentication process. Then, as a result of the authentication processing, when the authentication is OK, the locking device 18 is locked. In this case, in addition to the case where the resident goes out, the resident can lock only by touching the door knob 17 when the resident returns home.

  In the above case, it is determined from the indoor side the locking device 18 by determining whether the resident has touched the indoor doorknob 17a based on the detection result from the doorknob sensor 23a in the unlocked state of the locking device 18. It is conceivable to determine whether a locking operation has been performed.

  (7) In the above embodiment, when the resident unlocks the locking device 18 when the resident goes out, the locking device 18 is unlocked based on the resident touching the doorknob 17a on the indoor side, Alternatively or additionally, the locking device 18 may be unlocked by the unlocking operation by the thumb turn 18a.

  In this case, based on the detection result from the locking / unlocking detection sensor 22, it is determined whether or not the locking device 18 is switched from the locked state to the unlocked state. That is, it is determined whether or not the resident has performed an unlocking operation by the Samturn 18a from the indoor side. When it is determined that the unlocking operation has been performed, it is determined in step S13 that the resident goes out. After the determination, the resident identification process (step S14) and the at-home information update process (step S15) are performed as in the above embodiment.

  (8) In the above embodiment, the locking and unlocking system of the present invention is applied to the entrance door 16 provided at the entrance 15. However, for example, a door provided at another entrance such as a door provided at a self-port The door locking and unlocking system of the present invention may be applied to the door.
