  However, in the smart key system as described above, if the user goes outside without having an electronic key and then the locking device is in a locked state, the locking device cannot be unlocked, It may be inconvenient to return indoors. For example, it is considered that the same inconvenience arises when the occupant enters the locked state after the resident temporarily goes outdoors for gardening (gardening) or the like. Also, not limited to the smart key system, when the user goes outside without having the front door key (key), and then the front door is locked (for example, an infant accidentally locks) It is thought that the same inconvenience arises in

  The present invention provides a door control system for a building that allows a resident outside to enter the house without having a key such as a front door, thereby improving the convenience of going in and out of the house. The main purpose is to provide it.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  The door control system of the present invention includes a first door (entrance door 22) provided at an opening (entrance door 21) such as an entrance that is normally used by a user when entering and leaving the room, and other than the opening. It is applied to the building provided with the 2nd door body (the glass door 32, the doorway door 42) provided in the opening part (sweeping window 31, the doorway 41). And the portable communication apparatus (portable machine 52) which is carried by the user and stores identification information (user ID information) for each user, and the transmission provided from the portable communication apparatus provided near the second door body. An outdoor receiving device (window communication device 34) capable of receiving identification information, and a second door locking device (window) provided on the second door body based on the identification information received by the outdoor receiving device And a second door body control means (window controller 36) for performing the locking / unlocking control of the locking device 33).

  In a building having the above configuration, when a user tries to enter the building, the user normally opens the first door from the outdoor side and enters the building. In the present invention, in particular, in addition to opening the first door body and entering the building, the second door body can be opened from the outdoor side and enter the building. That is, on the condition that the predetermined identification information transmitted from the portable communication device is received through the outdoor receiving device, the second door body locking device can be unlocked and enter and exit through the second door body. It has become. As a result, a user who carries the portable communication device, that is, a resident of the building, can enter the building from other than the opening (entrance) that normally enters and exits. Therefore, in the case where the user goes outside without having the key for the first door, such as the key for the entrance door, the inconvenience of returning to the indoor is eliminated. As a result, it is possible for a resident outside to enter the room without having a key such as a front door, thereby improving the convenience of going in and out of the room.

  In addition, in this specification, "the opening part normally used by the user when going in and out of the room and the opening part other than the opening part" is an opening part that leads to the inside and outside of the building, and the "door body" Includes pivoting doors and sliding sliding doors.

  In the second invention, a first door locking device (entrance locking device 23) provided on the first door and an electronic key (electronic key 51) carried by the user separately from the portable communication device. ) And a first door body control means (entrance controller 25) for performing locking / unlocking control of the first door body locking device. That is, for example, for the entrance door, the locking device is locked and unlocked by wireless communication with the electronic key. Here, when the user goes out of the building without having the electronic key, the locking device for the first door (entrance door) cannot be automatically unlocked, but the identification transmitted from the portable communication device as described above. When the second door locking device is unlocked based on the information, it can return to the building through the second door.

  In the third invention, when the second door body control means unlocks the second door body locking device based on the identification information received by the outdoor receiver, a predetermined time has elapsed. Then, the locking device is set to the locked state. Thereby, after the second door body locking device is unlocked as necessary, the locking device is automatically returned to the original locked state, which is a preferable configuration for crime prevention.

  In 4th invention, it applies to the building provided with two or more opening parts other than the opening part which a user normally uses when going in and out of the said indoor / outdoor, The said 2nd door body control means is provided in each of these opening parts. In the door body control system for performing locking / unlocking control using any one of the door bodies as the second door body, the second door body to be controlled by the control means for the second door body is a user. Can be selected by the input operation. In this case, it is possible to enter / exit the building using an opening that is convenient for the user (any one of the openings other than the opening that is normally used by the user when entering / exiting indoors / outdoors). Is further improved.

  At this time, not all doors provided in openings other than the openings normally used by the user when entering / exiting indoors / outdoors are controlled for locking / unlocking. By setting only the door body as a control target, it is possible to avoid the inconvenience that the security performance is lowered due to arbitrarily performing the locking / unlocking control of each door body.

  In the fifth invention, the change of the second door body to be controlled is permitted on the condition that the identification information received from the portable communication device is identification information of a specific user determined in advance. That is, in this case, only the specific user authorized in advance can change the second door body to be controlled. Therefore, the second door body is inadvertently changed by the user, and as a result, when the user tries to open the second door body and enter the building, the user cannot do so, or an unintended door body is opened. Inconvenience can be suppressed.

  According to a sixth aspect of the invention, there is provided biometric information acquisition means (sound detector 35) for acquiring biometric information of the user, and the second door body control means is provided with the identification information transmitted from the portable communication device. In addition, locking / unlocking control of the second door locking device is performed based on the biological information acquired by the biological information acquiring means. In this case, since the second door body locking device is unlocked by both the identification information from the portable communication device and the biological information, it is more appropriate whether or not the second door body locking device is unlocked. I can judge. Thereby, crime prevention can be improved in the structure which enables the approach into a building through a 2nd door body.

  According to a seventh aspect of the invention, there is provided voice recognition means (voice detector 35) for recognizing the voice uttered by the user, wherein the second door body control means registers in advance with voice information recognized by the voice recognition means. The registered information is collated, and the lock control of the second door locking device is performed based on the collation result. The voice recognition means is preferably provided in the vicinity of the second door body (the same applies to the ninth invention described later). Further, as in the eighth invention, the second door body control means is provided on the condition that a predetermined word (a secret word or the like) registered in advance is included in the voice information recognized by the voice recognition means. In addition, the second door locking device may be unlocked. It should be noted that the prescribed words (passwords etc.) may be determined for each user.

  According to this structure, the conditions for unlocking the second door locking device can be easily set by recognizing the user using the voice information.

  In the ninth invention, voice recognition means (speech detector 35) for recognizing voice uttered by the user, and response message output for outputting a response message by voice or image based on voice information recognized by the voice recognition means Means (window controller 36). In this case, the user can receive a response message by voice or image when trying to unlock the second door locking device to enter the building through the second door. Therefore, a safe operation can be performed for a regular user, and a suspicious person who is not a regular user can be intimidated.

  As in the tenth aspect of the invention, the opening other than the opening that is normally used by the user when going in and out of the room is preferably a sweep window or a door (a doorway for kitchens and kitchens). That is, in this case, the glass door provided in the sweep window and the service door provided in the service door are used as the second door body. A user such as a resident may work in the area outside the sweep window (terrace, etc.) or the area outside the doorway. When doing so, he wants to enter the house from the window or doorway without going to the entrance door. Although it is assumed that there is something to think about, according to the above-described present invention, it is possible to enter the room indoors through a sweep window or a user's door as the user needs.

  Hereinafter, an embodiment in which the door control system of the present invention is embodied will be described with reference to the drawings. FIG. 1 is a diagram schematically showing a floor plan layout in a first floor portion of a building.

  As shown in FIG. 1, a building (house) 10 includes a front door 11 and rooms 12, 13, 14, and 15 made up of a living room, a kitchen, and the like as main building spaces. A front door 21 is provided in the front door 11, and a front door 22 is provided in the front door 21. The room 12 (for example, a living room) is provided with a sweep window 31, and the sweep window 31 is provided with a glass door 32. Further, the room 13 (for example, a kitchen) is provided with a service port 41, and the service port 41 is provided with a service port door 42.

  In this embodiment, the entrance 21 corresponds to “an opening that is normally used by a user when going in and out of the room”, and the user normally enters and exits the building 10 through the entrance 21. Further, the sweep window 31 and the user's mouth 41 correspond to “an opening other than the opening normally used by the user when going in and out of the room”. In addition, in the building 10, there is an opening corresponding to “an opening other than the opening normally used by the user when going in and out of the room” in addition to the sweep window 31 and the user entrance 41, but is omitted here for convenience. To do.

  FIG. 2 is a schematic diagram showing a configuration related to locking / unlocking control at the entrance door 22 and the glass door 32 of the sweep window 31. In addition, although description is abbreviate | omitted, it becomes the same structure also when it implements locking / unlocking control about the front door 42 of the front door 41 instead of the glass door 32 of the sweep window 31. FIG.

  As shown in FIG. 2, the entrance door 22 is provided with an entrance locking device 23 made of an electric cylinder lock. Since the entrance locking device 23 is not a new configuration, it will be briefly described. The locking device 23 includes a lock bar and an electrically driven actuator (both not shown), and the lock bar is driven by the actuator. And the entrance door 22 is configured to be either locked or unlocked. That is, the entrance door 22 is locked when the lock bar is in the protruding state, and the entrance door 22 is unlocked when the lock bar is shifted from the protruding state to the immersive state.

  In this system, the locking and unlocking of the entrance locking device 23 is automatically controlled by wireless communication with the electronic key 51 carried by a resident or the like (user U in the figure). As a configuration for the control, An entrance communication device 24 and an entrance controller 25 are provided. The entrance communication device 24 is provided in the vicinity of the entrance door 22 (or on the side of the entrance door 22), and a predetermined area near the entrance door is a communication area. The entrance controller 25 includes a microcomputer having a CPU, a memory, and the like, and the entrance locking device 23 and the entrance communication device 24 are electrically connected to the entrance controller 25. Information received from the electronic key 51 is transmitted to the entrance controller 25 through the entrance communication device 24. The entrance controller 25 determines whether to unlock or lock the entrance locking device 23 based on information received from the entrance communication device 24, and outputs an unlock signal to the entrance locking device 23 when unlocking. When locking, a locking signal is output to the entrance locking device 23.

  The electronic key 51 corresponds to a smart key put into practical use in the smart key system, and ID information (smart ID information) is set for each key 51. The electronic key 51 transmits smart ID information in response to a request from the entrance controller 25.

  Here, the front door communication device 24 transmits a request signal constantly or at a predetermined time period, whereas the electronic key 51 enters a communicable area with the front door communication device 24 and receives the request signal. In response to the request signal, the smart ID information is transmitted to the entrance communication device 24. After the smart ID information is transmitted to the entrance controller 25, the entrance controller 25 performs authentication based on the smart ID information and outputs an unlock signal or a lock signal to the entrance lock device 23. At this time, if the smart ID information received from the electronic key 51 corresponds to the authorized user, the entrance locking device 23 is automatically unlocked. On the other hand, if the ID information does not correspond to the authorized user, the entrance locking device 23 is not unlocked.

  The glass door 32 of the sweep window 31 is provided with a window locking device 33 made of an electric crescent lock. Since the window locking device 33 is not a new configuration, it will be briefly described. The locking device 33 includes a crescent (handle) having an arcuate hook and an electrically driven actuator (both not shown). The crescent is rotated by driving of the actuator, and the glass door 32 is in a locked or unlocked state. That is, when the crescent is rotated in one direction and the hook is engaged with the fixed hook, the glass door 32 is locked, and the crescent is rotated in the opposite direction to release the engagement. The glass door 32 is unlocked.

  In this system, in addition to the electronic key 51, the locking and unlocking of the window locking device 33 is automatically controlled by wireless communication with a portable device 52 carried by a resident (user U in the figure). As a configuration for control, a window communication device 34, a sound sensor 35, and a window controller 36 are provided. The window communication device 34 is provided in the vicinity of the glass door 32 (or on the side surface of the glass door 32), and a predetermined area near the glass door is a communication area. The voice detector 35 includes a microphone and an amplifier circuit. The voice detector 35 detects the voice generated by the user U with the microphone, and amplifies the voice signal with the amplifier circuit and outputs the amplified voice signal.

  The window controller 36 includes a microcomputer having a CPU, a memory, and the like, and a window locking device 33, a window communication device 34, and a sound sensor 35 are electrically connected to the window controller 36. Information received from the portable device 52 is input to the window controller 36 through the window communication device 34 and user voice information sensed by the voice sensor 35 is input. The window controller 36 determines whether to unlock or lock the window locking device 33 based on the received information from the window communication device 34 and the user voice information. When unlocking, the window controller 36 unlocks the window locking device 33. A lock signal is output, and when locking, a lock signal is output to the window locking device 33.

  The portable device 52 is composed of a small portable device, and is not easily disturbed even if it is carried. For example, a bracelet-type portable device with a wristband attached to the portable device, a pendant-type portable device with a neck chain attached to the portable device, or a badge with a spring hook or badge pin attached to the portable device. It can be realized as a portable mobile device. It is also possible to use a mobile phone used daily as the mobile device 52 or an IC card having a communication function as the mobile device 52.

  The portable device 52 has a memory (not shown) as a storage unit, in which unique ID information (user ID information) is stored for each owner (user U or the like). The user ID information is set separately from the above-described smart ID information, and is information that allows at least a plurality of users (for example, family members who live together) who are authenticated by this system and are to be authenticated individually. It has become.

  Here, the window communication device 34 transmits the request signal constantly or at a predetermined time period, whereas the portable device 52 enters the communicable area with the window communication device 34 and receives the request signal. In response to the request signal, user ID information is transmitted to the window communication device 34. Then, after the user ID information is transmitted to the window controller 36, the window controller 36 performs authentication based on the user ID information and performs locking / unlocking control of the window locking device 33 based on the authentication result.

  Next, the flow of the locking / unlocking control of the window locking device 33 by the window controller 36 will be described based on the flowchart of FIG. This control process is executed by the window controller 36 at a predetermined time period.

  In FIG. 3, a request signal transmission process is executed in step S <b> 11, and in subsequent step S <b> 12, it is determined whether user ID information is received from the portable device 52 in response to the request signal. If there is no response, that is, if user ID information has not been received, this process ends.

  When there is a response, that is, when user ID information is received, the process proceeds to step S13, and user authentication is performed based on the received user ID information. If the authentication is OK, step S14 is affirmed and the process proceeds to the subsequent step S15. If the authentication is NG, step S14 is denied and the process is terminated. When user ID information is received from a plurality of portable devices, if at least one of the received information from each portable device is OK, the process proceeds to step S15.

  In step S15, voice recognition processing is performed by analyzing the voice information of the user sensed by the voice sensor 35. Specifically, the voice information recognized by the voice detector 35 is collated with the registered information registered in advance, and the pre-registered defined words (challenge etc.) are included in the voice information recognized each time. It is determined whether or not. The prescribed word is, for example, “Open the door. ], And this specified word is determined for each user.

  Thereafter, in step S16, it is determined whether or not the voice authentication by the voice recognition process in step S15 is OK. If the voice authentication is OK, the process proceeds to step S17. In step S <b> 17, an unlock signal is output to the window locking device 33 in order to unlock the window locking device 33 of the sweep window 31. As a result, a user on the outdoor side of the sweep window 31 can enter the room through the sweep window 31.

  Here, when the window locking device 33 of the sweep window 31 is automatically unlocked in the step S17, the elapsed time from the unlocking is measured, and when the elapsed time reaches a predetermined time (for example, 10 minutes). The window locking device 33 of the sweep window 31 may be returned to the original locked state.

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

  Based on the user ID information transmitted from the portable device 52 and the voice information of the user sensed by the voice sensor 35, the lock / unlock control of the window locking device 33 of the sweep window 31 is performed. In addition to unlocking the entrance door 22 (entrance locking device 23) from the outdoor side and entering the building 10 with the electronic key 51, the glass door 32 (window locking device 33) of the sweep window 31 is unlocked from the outdoor side. It becomes possible to enter the building 10. That is, when the resident goes outside without having the electronic key 51 (key for the entrance door), he can enter the room from outside the entrance. Therefore, in the case where the electronic key 51 is forgotten indoors and it is left outdoors, or when an infant or the like accidentally locks the front door locking device 23, the inconvenience of returning to the indoor is eliminated. . In addition, the resident may perform gardening or the like in an outside area (such as a terrace) of the sweep window 31, and can enter the sweep window 31 without going to the entrance 21. As described above, it is possible for a resident who is outdoors to enter the room without having a key such as a front door, thereby improving the convenience of going in and out of the room.

  Since the user's voice information is adopted as the information for authenticating the user in addition to the user ID information, it can be more appropriately determined whether or not the window locking device 33 of the sweep window 31 is unlocked. Thereby, even if it is the structure which enables the approach into the building 10 through the sweep window 31, crime prevention can be improved.

  According to the configuration in which the locking / unlocking control is performed based on the user's voice information, the conditions for automatically unlocking the window locking device 33 of the sweep window 31 can be easily set. In addition, when performing voice authentication based on voice information, the reliability of user authentication can be improved by registering a prescribed word (a secret word or the like) for each user. It is desirable that the specified word is updated as appropriate.

  It is preferable in terms of crime prevention because the locking device 33 is set to the locked state when a predetermined time has elapsed after the window locking device 33 of the sweep window 31 is automatically unlocked based on the user ID information and the user's voice information. It becomes composition.

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

  Which of the door bodies provided in the openings other than the entrance 21 in the building 10 (the sweep window 31 and the free entrance 41) is to be controlled, that is, which is unlocked by the user ID information, The selection may be made by a user input operation. For example, the door body to be controlled is changed by an input operation on the window controller 36 or an input operation on a management personal computer provided in a building. In this case, it is possible to enter / exit the building 10 using an opening that is convenient for the user (any one of the openings other than the opening that is normally used by the user when entering / exiting indoors / outdoors). The property is further improved.

  Here, the limited doors that are selected each time, rather than carrying out locking / unlocking control for all doors provided in openings other than the openings that are normally used by the user when entering and exiting indoors and outdoors. It is better to control only the body. For example, when the glass door 32 is selected as a control target, the locking / unlocking control (automatic unlocking) is not performed on the doorway door 42. As a result, it is possible to avoid the inconvenience that the crime prevention performance is lowered due to arbitrarily performing locking / unlocking control of each door.

  As described above, in the configuration in which the door to be controlled can be selected, the user ID information received each time is the ID information of a specific user determined in advance, on the condition that the door to be controlled ( It is preferable to allow the change of the second door body. For example, only the householder in the family can select the control target. As a result, the door body (second door body different from the entrance door) to be controlled is changed carelessly for the resident, and as a result, the user opens the second door body and enters the building. Therefore, it is possible to suppress inconveniences that cannot be achieved or that an unintended door body is opened.

  In the above embodiment, when performing voice authentication based on the voice information, the voice information recognized by the voice detector 35 and the registered information registered in advance are collated and registered in advance in the recognized voice information. The configuration is such that it is determined whether or not a specified word (a secret word or the like) is included, but this is changed. For example, voice authentication is performed based on a voiceprint extracted from voice information. In this case, user authentication is performed by comparing the voiceprint extracted from the voice information with the user's voiceprint registered in advance.

A response message may be created and output based on the user's voice information recognized by the voice sensor 35, and the lock / unlock control of the window locking device 33 may be performed after the output of the response message. The response message may be generated by, for example, the window controller 36 and output as a voice message or an image message. Specifically, control is performed as in the following (1) and (2).
(1) When the user utters a voice such as “I am now” outdoors (near the sweep window 31), the system recognizes the voice and outputs a voice message such as “Please come home”. Thereafter, the window locking device 33 is unlocked. This provides a sense of security for the user.
(2) When the user utters a voice such as “I'm right” outdoors (near the sweep window 31), the system recognizes the voice and outputs a voice message such as “Please use the secret”. When the user returns a voice such as “open sesame” as a response, the system side recognizes the voice again, confirms that the voice information is normal, and then unlocks the window locking device 33. Thereby, a crime prevention effect can be expected.

  According to the above configuration, the user can receive a response message by voice or image when trying to unlock the window locking device 33 to enter the building through the glass door 32 of the sweep window 31. This makes it possible for the user to perform a safe operation, and for a suspicious person who is not a legitimate user to perform a threat.

  Information other than the voiceprint included in the voice information can also be used as the user's biometric information. For example, it is possible to perform locking / unlocking control based on fingerprint information read by a fingerprint reading device (corresponding to biometric information acquisition means), iris information read by an iris reading device (corresponding to biometric information acquisition means), or the like. is there.

  In the above embodiment, the entrance controller 25 (corresponding to the control means for the first door body) that performs the locking / unlocking control of the entrance locking device 23 and the window controller 36 (the second door body) that performs the locking / unlocking control of the window locking device 33. Is equivalent to the control means), but it is also possible to change this and configure the same controller.
