  FIG. 5 is a diagram showing the response information 21 and the visitor information 63 stored in the storage unit 79 in the first embodiment of the present invention. FIG. 6 is a diagram illustrating an example of an input screen displayed on the display unit 86 when the response information 21 is input to the storage unit 79 in the first embodiment of the present invention. FIG. 7 is a diagram illustrating an example of a display screen of the display unit 86 when displaying the visitor information 63 previously stored in the storage unit 79 in the first embodiment of the present invention.

  The visitor information 63 includes the name of the visitor 12 or its affiliation, the reading of the name, the telephone number of the visitor 12, an image captured in the past by the visitor imaging means 26, and a visit previously input via the outdoor microphone 44. The voice information including the voice of the person 12 and the response content information in a plurality of modes are included. Although the name may be the name of the visitor 12, in the first embodiment, the name is a type name classified and determined by the visitor identification means 27. When the visitor identification means 27 cannot classify the visitor 12 among a plurality of predetermined types, the visitor identification means 27 is classified as “others”, and the name is corrected by a home person who operates the operation unit 74. May be.

  The response information 21 is determined according to a plurality of predetermined cases and each type of the visitor 12. In the example shown in FIG. 5, at least three of the types are illustrated, and each type is referred to as types T1 to T3. The plurality of cases determined in advance are the following three situations (a) to (c), where the situation (a) indicates that “all of the residents are located in at least one of the toilet 34 and the bathroom 36. The situation (b) is “a situation in which the home-responder can immediately respond to the visitor 12”, and the situation (c) "Situation without". Specifically, the situation (b) is “a situation where the home is found in other parts of the residence 18 except for the toilet 34 and the bathroom 36”.

  The situation (a) is responded with the content of the correspondence A to any of the three types of visitors 12. Correspondence A is a response with response information 21 including voice information and text information, “I can't do anything right now. Please wait for a while or come after 30 minutes.” Therefore, in the situation (a), the voice information is output from the outdoor speaker 46 and the character information is displayed on the outdoor display unit 48. This response content is an example, and may be another wording, or may be set by selection from among a plurality of options, and is set by a home person inputting via the operation unit 74. It is also possible to record the response contents by recording the voice of the operated person.

  The situation (b) is responded to the visitor 12 with the content of the correspondence B in any of a plurality of types. Correspondence B corresponds to response information 21 indicating that neither audio output from the outdoor speaker 46 nor display by the outdoor display unit 48 is performed. If the home visitor can respond immediately to the visitor 12, there is no problem in keeping the visitor 12 waiting until the home visitor responds to the visitor 12.

  The situation (c) corresponds to the visitor 12 of the type T1 with the content of the correspondence C1, and the visitor 12 of the type T2 corresponds to the content of the correspondence C2, and the visitor 12 of the type T3. Is handled by the content of the correspondence C3. Correspondence C1 corresponds to response information 21 including voice information and text information that “I will call you later”. The voice information is output from the outdoor speaker 46, and the character information is displayed on the outdoor display unit 48. This response content is also an example, and may be configured to select from a plurality of options, or may be configured to store the response content by input.

  Correspondence C2 is a response in response information 21 including voice information and character information “please leave at ZZ convenience store”. “ZZ” is an example and is replaced by a proper noun of a convenience store. The voice information is output from the outdoor speaker 46, and the character information is displayed on the outdoor display unit 48. Correspondence C3 corresponds to response information 21 including voice information and text information “Please come again at 20:00”. The correspondences C2 and C3 are also examples of response contents, and may be configured to select from a plurality of options, or may be configured to store response contents by input.

  FIG. 8 is a flowchart showing the steps of the method for responding to the visitor 12 in the first embodiment of the present invention. FIG. 8 shows a process when there is one resident. After the start of processing, the process proceeds to step a1, and it is determined whether or not a person is present in a predetermined area in the residence 18. The predetermined region is a range captured by the camera 32 in the first embodiment. When it is determined that the person is at home, the process proceeds to step a2 to determine whether or not the person is at the toilet 34. If it is determined in step a1 that the resident is not at home, the process proceeds to step a6 described later.

  If it is determined in step a2 that the person is not at the toilet 34, the process proceeds to step a3 to determine whether the person is in the bathroom 36 or not. If it is determined in step a2 that the position of the person is the toilet 34, and if it is determined in step a3 that the position of the person is the bathroom 36, the situation corresponds to the situation (a) and the process proceeds to step a4. Then, response A is performed. If it is determined in step a3 that the person is not located in the bathroom 36, the situation corresponds to the situation (b), the process proceeds to step a5, and action B is performed. If it is determined in step a1 that the resident is not at home, the process proceeds to step a6, and the type of the visitor 12 is determined.

  If this process is referred to as a visitor 12 type determination process, if it is determined in the visitor 12 type determination process that the type of the visitor 12 is the type T1, the process proceeds to step a7 and a response C1 is performed. If it is determined that the type of the visitor 12 is the type T2 in the visitor 12 type determination step, the process proceeds to step a8, and the response C2 is performed. If it is determined in the visitor 12 type determination step that the type of the visitor 12 is the type T3, the process proceeds to step a9, and the corresponding C3 is performed. After performing the actions A, B and C1 to C3, the present process is terminated. If there is a visitor 12 again, this process is started again.

  The correspondence other than correspondences A, B and C1 to C3 may include a correspondence that the visitor 12 contacts the mobile phone that the visitor 12 has visited. In this case, the response information 21 includes information about a procedure for contacting the mobile phone. Specifically, information indicating that the visitor 12 has visited may be transmitted to the mobile phone by e-mail. Moreover, the response | compatibility of transferring the audio | voice information acquired via the outdoor microphone 44 as a telephone call to a mobile telephone may be included.

  As a result, a resident who is out of the office with a mobile phone can talk with the visitor 12 via the mobile phone and the intercom device 10. Moreover, it is good also as a structure which does not perform the visitor 12 type | mold determination process like step a6, and performs the common response | compatibility with respect to all the visitors 12 in the situation (c) where the resident is not at home.

  Information indicating that the visitor 12 has arrived is notified to the home residents by outputting a predetermined voice in the residence 18 immediately after the visit is detected. In the first embodiment, this notification is notification by outputting voice information representing the doorbell electronically stored in the storage means 79.

  When the visitor 12 visits and a visit is detected, the outdoor imaging means performs imaging, and a video having a predetermined length with respect to time is temporarily recorded in the visitor storage unit 58. This temporary recording is performed once for each visit. In the first embodiment, the visitor information 63 stores one for one type even if there are multiple visits. As one visitor information 63, a video may be stored as a moving image, but in the first embodiment, it is possible to effectively use the capacity of the storage medium by storing one still image rather than a moving image. Therefore, one visitor information 63 includes one still image. In another embodiment, one visitor information 63 may include a plurality of, for example, two or three still images.

  As shown in FIG. 6, the temporarily recorded video is displayed to the resident, and the visitor information 63 is determined by the resident based on the video information representing this video. The confirmation of the visitor information 63 by the home visitor may be performed after the automatic or manual response to the visitor 12 is completed, and may be performed after the visitor 12 finishes the visit and returns. The home resident operates the operation unit 74, selects image information representing one or more images from the image information included in the video information, and includes the information in the visitor information 63. As described above, the visitor information 63 may include other names, readings, telephone numbers, and memo information representing related contents in characters. Moreover, in 1st Embodiment, the information of who the visitor 12 of each type was the visitor 12 among the residents who live in the residence 18 is also included. When this is unknown, it may be excluded from the visitor information 63 as a matter of course. The visitor information 63 may include information indicating that the visit was made to all residents.

  As shown in FIG. 7, the visitor information 63 can be read by operating the operation unit 74. This is performed by the control unit 17 reading out information stored in the visitor information 63 storage unit and displaying the information on the display unit 86 in response to an operation by the operation unit 74, whereby 63 can be confirmed at any time. Information displayed on the display unit 86 may be a part or all of the visitor information 63. The display unit 86 can also display a plurality of response contents associated with each type of visitor 12, and the associated response contents can be changed by operating the operation unit 74.

  FIG. 9 is a diagram illustrating an example of a display screen when the display unit 86 displays the visit history information 110 in the first embodiment of the present invention. FIG. 10 is a diagram illustrating an example of the visit history information 110 according to the first embodiment of this invention. The visitor storage unit 58 can store the visit of the visitor 12 and the identification result by the visitor identification means 27 at each visit, and the display unit 86 records the visit of the visitor 12 as a history. Can be displayed as visible.

  The visit history information 110 representing the visit history is set to include the video imaged by the outdoor imaging means and the identification result by the visitor identification means 27. As shown in FIG. 9, the display unit 86 may display information on the amount of electric power obtained by solar power generation acquired through the solar information receiving unit 93 together with the visit history information 110. Furthermore, it is good also as a structure which displays the information of power consumption.

  According to the first embodiment, the in-resident detection unit 11 detects at least one of the presence position and the situation of the person inside the residence 18. The control unit 17 selects one or a plurality of response information 21 from the plurality of response information 21 stored in the response information storage unit 13 based on the detection result by the in-house detection unit 11, and the selected response information 21 is selected. The output means 16 outputs the response content represented by

  This makes it possible to change the response content to the visitor 12 according to the position of the person inside the residence 18. For example, when the position of the person in the residence 18 is limited to only at least one of the toilet 34 and the bathroom 36, or when the activity of the person is detected only in at least one of the toilet 34 and the bathroom 36 In addition, information on both the fact that an immediate response to the visitor 12 is impossible and the fact that the visitor 12 has been notified to the person in the residence 18 is notified to the visitor 12. It is also possible to reflect the response contents. Therefore, the response content to the visitor 12 can be the response content according to the status of the home-staying person.

  Further, according to the first embodiment, the intercom device 10 is configured to further include the visitor imaging unit 26 and the visitor identification unit 27. The visitor imaging means 26 images the visitor 12 and acquires the visitor 12 image. The visitor identification means 27 identifies the visitor 12 by analyzing the image of the visitor 12. The control unit 17 selects one or a plurality of response information 21 to be output to the output unit 16 based on the identification result by the visitor identification unit 27. As a result, the response content can be changed according to the difference between the visitors 12. For example, the response content can be changed according to any one or more of the number, sex, uniform, and person of the visitor 12, so that the response content can be adapted to the role or purpose of the visitor 12. Can be.

  Moreover, according to 1st Embodiment, the detection means 11 in a residence detects the presence position of a person. Thereby, for example, information on whether or not a person is present can be acquired in a place where it is difficult to immediately respond to a visitor such as the bathroom 36. Accordingly, when the location where the person is present is difficult to instantly respond to the visitor such as the bathroom 36, it is impossible to immediately respond to the visitor 12, and the person in the residence 18 Both of the information that the visitor 12 has been informed can be reflected in the response content to the visitor 12. Therefore, the response content to the visitor 12 can be the response content according to the status of the home-staying person.

  The in-resident detection means 11 determines whether the toilet 34 is a person's presence position. As a result, it is possible to acquire information on whether or not a person exists in the toilet 34. Therefore, when the toilet 34 is located at a person, it is informed that the visitor 12 cannot be immediately responded and that the visitor 12 has come to a person in the residence 18. This information can be reflected in the response content to the visitor 12.

(Second Embodiment)
FIG. 11 is a block diagram showing the configuration of the intercom apparatus 10 according to the second embodiment of the present invention. The intercom apparatus 10 according to the second embodiment is similar to the intercom apparatus 10 according to the first embodiment, and hereinafter, the description will focus on differences between the second embodiment and the first embodiment.

  The in-housing detection means 11 acquires predetermined types of information about a person whose presence position and / or situation has been detected inside the dwelling 18. This predetermined type of information is one or more types of information among audio information, image information, and counting information. The intercom device 10 further includes a resident identification unit 111, and the resident identification unit 111 includes a resident information storage unit 112. The resident information storage unit 112 lists and stores the personal attribute information 113 of the resident who lives in the residence 18. The resident personal attribute information 113 is at least a part of information such as the gender, date of birth, height, and weight of each resident. Further, the resident personal attribute information 113 may include an analysis result of an image obtained by capturing each resident.

  The resident identification means 111 identifies the detected person by analyzing the predetermined type of information acquired by the in-resident detection means 11 for the detected person. The control unit 17 selects one or a plurality of response information 21 to be output to the output unit 16 based on the identification result of the resident identification unit 111. The resident information storage unit 112 is provided in the storage unit 79 and realized by including any one device configuration such as a RAM, an HDD, and an SSD.

  In the second embodiment, the predetermined type of information acquired by the in-resident detection unit 11 includes image information. The resident information storage unit 112 stores information regarding the image of the resident living in the residence 18. When the person presence determination unit 24 determines that a person is captured, the resident identification unit 111 includes an indoor image in which a person is captured and a resident image stored in the resident information storage unit 112. Compared with the information on, the analogy judgment.

  The visitor storage unit 58 stores the visitor 12 image captured by the visitor imaging unit 26, and the visitor storage unit 58 displays the identification result of the visitor 12 image by the visitor identification unit 27 as the resident information. The information is stored in association with information of at least some of the residents stored in the storage unit 112.

  The intercom apparatus 10 further includes a plurality of notification means 114. The plurality of notification means 114 are controlled by the control means 17 and notify each person inside the residence 18 according to the position of each person. When the visitor 12 visits and the identification result by the visitor identification means 27 indicates that it is associated with a part of the resident person, the control means 17 includes the part of the resident person. Control is performed so that the notification by the notification means 114 corresponding to the presence position is performed earlier than the notification by the other notification means 114.

  The resident identification means 111 determines that the person's face included in the indoor image is a person's face, and identifies who the resident is. For example, in the case of a kitchen, the camera 32 is installed at a position where it is easy to capture the face of a person standing on the sink 38. In the case of the room 28, the face of the person entering the room is installed at a position where it is easy to image. The same method as the identification by the visitor identification means 27 can be used to determine whether or not the face is a person and to identify who is a resident. When the face is not reflected in the indoor image captured by the camera 32, or when a person other than the resident is captured, when “who cannot be identified” or “others” It may be determined that the person is a person.

  In the second embodiment, when the visitor 12 comes, the visitor 12 is determined based on the visitor information 63 stored in the visitor storage unit 58. That is, the type of the visitor 12 is determined based on information indicating who the visitor 12 visited. Based on the determination result, if the resident who has visited is at home, the notification to the resident who has visited is given priority over the notification to other residents who have not been visited.

  In the second embodiment, video information captured by the outdoor camera 42 and audio information acquired by the outdoor microphone 44 are recorded and recorded. For this purpose, as shown in FIG. 11, the intercom apparatus 10 further includes a video codec unit 116 and an audio codec unit 118. The video codec unit 116 stores a video codec, which is a protocol necessary for recording and playing back video. The audio codec unit 118 stores an audio codec that is a protocol necessary for recording and reproducing audio.

  FIG. 12 is a flowchart showing the steps of a method for responding to a visitor 12 according to the second embodiment of the present invention. After the start of this process, the process proceeds to step b1, and the visitor 12 is detected. The detection of the visitor 12 may be performed by installing a sensor that senses the proximity of an object using infrared rays in the vicinity of the intercom outdoor unit 39, and in this second embodiment, the sensor is detected by the interphone outdoor unit 39. This is performed by detecting whether or not the provided push button 54 is pressed. If no visit is detected, it tries to detect it until it is detected.

  Next, the process proceeds to step b2, and the presence / absence of a person at home is determined and specified. This is done by identifying the indoor image captured by the camera 32 with the resident identification means 111. In other embodiments, identification may be performed in other ways. In step b2, if there is a person at home, even if it is impossible to identify the person at home, it is determined that “the person is at home” and the process proceeds to the next step.

  If there is a person at home in step b2, the process proceeds to step b3, where it is determined whether the presence position of the person at home is a position where response is possible. If the presence position of the home person is at least one or both of the toilet 34 and the bathroom 36 and the other place is not the presence position of the home person, it is determined that the response is impossible. When the presence position of the person at home is a position other than the toilet 34 and the bathroom 36 in the house 18, it is determined that the person is able to respond.

  If it is determined in step b3 that the presence position of the resident is a responsive position, the process proceeds to step b4, and the type of the visitor 12 is determined. In the specific example shown in FIG. 12, it is first determined whether or not it is a trader, and if it is determined, it is further determined which type the visitor 12 is. When the determination is impossible, for example, it may be set to determine that it is equivalent to the type of a specific trader. In this case, since the presence position of the person at home is a position where the response is possible, the situation corresponds to the “situation (b)” described with reference to FIG.

  If it is determined in step b4 that the contractor is a trader, the process proceeds to step b5, and a response is determined according to the type of the visitor 12. Next, the process proceeds to step b6, and a response corresponding to the content determined in step b5 is performed. Specifically, the notification is performed by all of the plurality of notification means 114 provided indoors. In this case, since the person at home can respond immediately, the operation by the outdoor speaker 46 and the outdoor display unit 48 is not performed on the visitor 12.

  If it is determined in step b4 that the visitor 12 is not a trader, the process proceeds to step b7, and a response corresponding to the type of the visitor 12 is performed. If the visitor 12 is a visitor 12 to some of the residents, the alerting means 114 installed at the place where the resident who has visited is made to ring the sound as a doorbell, Priority is given to other residents who have not been visited. In the second embodiment, a resident who has received a visit is given a priority by giving a notification earlier than a resident who has not received a visit, but in other embodiments, a loud sound is generated. It is good also as a structure which informs the resident who received the visit that it has received the visit.

  In step b3, when it is determined that there is a person at home but the position of the person at home is a place where a response cannot be made, the process proceeds to step b9, and the type of visitor 12 is determined. In step b9, it is first determined whether or not the visitor 12 is a trader, and the visitor 12 is further classified into a plurality of subdivided types. When the visitor 12 is a trader, the process proceeds to step b10, and a response corresponding to the type of the visitor 12 is determined. Specifically, the notification is performed by all of the plurality of notification means 114 provided indoors. In this case, since the presence position of the person at home is a position where a response is impossible, this corresponds to the “situation (a)” described with reference to FIG. For the merchant who is the visitor 12, the action determined in the type of the merchant in the situation (a) is selected. Next, the process proceeds to step b11, and a response corresponding to the content determined in step b10 is performed.

  If it is determined in step b9 that the visitor 12 is not a trader, the process proceeds to step b12, and a response is determined according to the type of the visitor 12. If the visitor 12 is a visitor 12 to some of the residents, the alerting means 114 installed at the place where the resident who has visited is made to ring the sound as a doorbell, Priority is given to other residents who have not been visited. Next, the process proceeds to step b13, and a response corresponding to the content determined in step b12 is performed.

  Even when it is determined in step b2 that there is no person at home, the sound is sounded by the notification means 114 indoors. Thereby, even when a home person is present and the location of the home cannot be specified, the home person can notice the visit of the visitor 12. If it is determined in step b2 that there is no home-staying person, the process proceeds to step b14 and the type of the visitor 12 is determined. In step b14, it is first determined whether or not the visitor 12 is a trader, and the visitor 12 is further classified into a plurality of subdivided types.

  If it is determined in step b14 that the visitor 12 is a trader, the process proceeds to step b15 to determine the correspondence according to the type of the visitor 12. Specifically, the notification is performed by all of the plurality of notification means 114 provided indoors. In this case, since there is no resident, this corresponds to the “situation (c)” described with reference to FIG. For the merchant who is the visitor 12, the action determined for the type of the merchant in the situation (c) is selected. Next, the process proceeds to step b16, and a response corresponding to the content determined in step b15 is performed.

  If it is determined in step b14 that the visitor 12 is not a trader, the process proceeds to step b17, and a response corresponding to the type of the visitor 12 is determined. If the visitor 12 is a visitor 12 to some of the residents, the alerting means 114 installed at the place where the resident who has visited is made to ring the sound as a doorbell, Priority is given to other residents who have not been visited. Next, the process proceeds to step b18, and a response corresponding to the content determined in step b17 is performed. Thereafter, the process proceeds to step b1 to determine whether or not there are visitors 12 again.

  FIG. 13 is a flowchart showing the steps performed on the visitor 12 in the method for responding to the visitor 12 according to the second embodiment of the present invention. FIG. 13 is a diagram for explaining the process of identifying the visitor 12 in steps b4, b9, and b14 in FIG. First, in step c1, the visitor 12 is detected. If no visit is detected, it tries to detect it until it is detected. This step is the same as step b1 described in relation to FIG. Next, the process proceeds to step c2, and imaging of the visitor 12 is started. The imaging of the visitor 12 is performed by the outdoor camera 42 controlled by the control means 17. Next, the process proceeds to step c3, and storage of the image obtained by imaging is started. The storage of the video is stored in the visitor storage unit 58 by the control means 17.

  Next, the process proceeds to step c4 where the visitor 12 is recognized. This is performed by analyzing the video obtained by the imaging by the outdoor camera 42 by the visitor identification means 27. Next, the process proceeds to step c5, and it is determined whether or not there is visitor information 63 corresponding to the identification result by the visitor 12 identification unit. This is performed by the control means 17 based on the visitor information 63 stored in the visitor storage unit 58.

  If it is determined in step c5 that the corresponding visitor information 63 exists, the process proceeds to step c6, where it is determined whether the user is a friend or an acquaintance. This is performed by the control means 17. If the friend or acquaintance is distinguished from the merchant and is determined to be a friend or acquaintance, the process proceeds to step c7, and the visitor 12 visits the visit partner. This is performed by the control means 17 extracting the resident personal attribute information 113 associated with the visitor 12 in the visitor information 63. Next, the process proceeds to step c8, and indoor response is performed. As described above, the indoor correspondence is preferentially notified to the resident who is the visiting partner of the visitor 12.

  Next, the process proceeds to step c9, and the visitor 12 is dealt with. The response to the visitor 12 at this time is performed according to the type of the visitor 12, the presence / absence of the home visitor, and the location of the home visitor, as described with reference to FIG. Next, the process proceeds to step c10, and imaging and video storage are finished. Thereafter, the process proceeds to step c1, and it is determined again whether there is a visitor 12 or not.

  If it is determined in step c6 that the person is not a friend or an acquaintance, it is determined that the person is a trader, the process proceeds to step c11, and the type of the trader is determined. Next, it transfers to step c12 and respond | corresponds indoors. In this case, the notification is made indoors regardless of the presence or absence of the resident, and even when there are a plurality of resident, the notification is equally made to all the resident without giving priority notification to a part of the resident. I do. Next, the process proceeds to step c13 to deal with the visitor 12. The response to the visitor 12 at this time is performed according to the type of the trader, the presence / absence of the resident, and the location of the resident as described with reference to FIG. Next, the process proceeds to step c10, and imaging and video storage are finished.

  In step c5, when it is determined that there is no visitor information 63 corresponding to the identification result of the visitor 12 among the visitor information 63 stored in the visitor storage unit 58, the process proceeds to step c14, and the visitor is visited. It is determined whether 12 is a wanted offender. Information about the wanted crime may be stored in advance in the storage means 79, and may be provided from the external database 121 via the Internet 120, for example. This determination is made by the control means 17 based on the acquired information about the wanted crime.

  If it is determined in step c14 that it is a wanted crime, the process proceeds to step c15 and a report is made to the police. Next, the process proceeds to step c16 and a predetermined response is made. This is determined in advance in response to the wanted criminal, and performs, for example, asking several questions by an automatic response, or increasing the resolution in imaging and continuing imaging. While this predetermined response is being performed, imaging, storage of video acquired by imaging, and audio recording are continuously performed. As a result, for example, voiceprint analysis can be performed later. Thereafter, the process proceeds to step c10, and imaging and video storage are finished.

  If it is determined in step c14 that the criminal is not a wanted person, the process proceeds to step c17, and a question to the predetermined visitor 12 is automatically output by voice. Next, the process proceeds to step c18, and the contents of the answer of the visitor 12 to the contents inquired by voice output are stored by recording. This is performed under the control of the control means 17 via the outdoor microphone 44 and recorded in the visitor storage unit 58.

When the person presence determination unit 24 determines that a person is captured, the resident identification unit 111 includes an indoor image in which a person is captured and a resident image stored in the resident information storage unit 112. Compared with the information on, the analogy judgment.

  Thereby, it can be determined whether or not a person exists at a plurality of different positions in the residence 18, and the captured person can be identified based on information stored in the resident information storage unit 112. Therefore, when the visitor 12 visits, the response content can be selected immediately according to the situation of the person at home.

(Third embodiment)
The intercom apparatus 10 according to the third embodiment is similar to the intercom apparatus 10 according to the second embodiment, and hereinafter, the description will focus on differences between the third embodiment and the second embodiment.

  In the third embodiment, the predetermined type of information acquired by the in-resident detection unit 11 includes count information about the weight. The dwelling detection means 11 includes a weight measurement unit, and the weight measurement unit performs weight measurement at one or a plurality of positions inside the dwelling 18 to acquire weight information. The resident information storage unit 112 stores information related to the weight of the resident living in the residence 18. The resident identification unit 111 compares the weight information acquired by the weight measurement unit with the information stored in the resident information storage unit 112, and makes an analogy determination.

  This makes it possible to acquire information related to the position of the person with high accuracy. For example, when a place where a person is likely to be located is local, such as the kitchen and the toilet 34, the area detected by the in-resident detection means 11 is locally changed to a place where the person is likely to be located. It becomes possible to arrange in. Further, in places where it is not preferable to acquire information on whether or not a person is present, such as a toilet 34, by capturing an image, diversity is added to the detection method by the in-house detection means 11, and versatility is achieved. High intercom device 10 can be realized.

  The third embodiment is particularly effective when there are a plurality of residents and the weights of the plurality of residents are different from each other. Although the weight of the same person also increases or decreases due to meals, exercise, bathing, etc., this embodiment is applicable when the difference in weight for each resident is greater than the difference due to daily weight changes of the same person. .

  For example, in the case of a kitchen, the weight measuring unit for measuring the body weight is provided on the floor located at the position where the human weight can be detected by standing in the vicinity of the sink 38, that is, at the foot of the person standing on the sink 38. For example, a Japanese style toilet 34 is provided on the floor next to the toilet, and a Western style toilet 34 is installed at a position such as under the toilet seat so that the body weight can be detected by sitting on the toilet seat.

  Moreover, in 3rd Embodiment, when the detection means 11 in a residence determines whether the bathroom 36 is a person's presence position or an activity place, it determines based on the flow volume of a water supply or a sewer. The dwelling detection means 11 includes a flow rate measuring unit and a flow rate determining unit. The flow rate determination unit measures the flow rate in the water supply or drainage channel in the bathroom 36. The flow rate determination unit determines whether or not the bathroom 36 is a person's presence position or activity place according to the measurement result of the flow rate measurement unit. Specifically, the flow rate determination unit refers to the measurement result of the flow rate measurement unit in units of time of several minutes to several tens of minutes, for example. As a result, in the bathroom 36, even if the flow rate becomes almost zero L / min in a time of several minutes or less, it is erroneously determined that the person is not in the bathroom 36 even though the person exists. Can be prevented.

  In the third embodiment, the dwelling detection means 11 includes a flow rate measurement unit and a flow rate determination unit, and the flow rate determination unit determines whether the bathroom 36 is a person's presence position or activity according to the measurement result of the flow rate measurement unit. Since it is determined whether or not it is a place, information on whether or not a person is active in the bathroom 36 can be acquired. In the bathroom 36, it may not be preferable to acquire information on whether or not a person is present, for example, by capturing an image. Therefore, the detection method by the in-house detection unit 11 is provided with diversity. A highly versatile intercom device 10 can be realized.

(Modification)
In FIG. 8 and FIG. 12, the in-house detection means 11 exemplifies the case where the person's location in the house 18 is the bathroom 36 and the toilet 34 as a case where an immediate response is impossible. If an immediate response is impossible even if there is a person, the person is not limited to the bathroom 36 and the toilet 34. For example, it may be determined that the situation is such that the person's situation is sleeping or studying in the study room is “a situation in which an immediate response is impossible”.

  Specifically, for example, it may be configured to determine the status of a person who is at home, that is, a resident, by detecting the distribution of the weight of the person in the nightclothes and its change over time. Further, as “a case where an immediate response is not possible”, the intercom device 10 may be configured such that a home person can add these conditions via the operation unit 74. Further, one or more conditions that the resident wants to set as “when immediate response is impossible” from a plurality of predetermined setting conditions may be selected and set. As a result, for example, when there is a person who refrains from taking an examination among residents, the intercom device 10 can be used even when there is a person who is difficult to move even in the residence 18. Therefore, the resident's various demands can be satisfied, and the versatile intercom device 10 can be realized.

  In another embodiment, the detection of the presence or absence of a person, that is, the method of detecting the presence of the visitor 12 and the person at home is any one of an infrared sensor, a thermal sensor, an ultrasonic sensor, a camera 32, a weight measurement, and the like. Alternatively, any two or more may be used in combination.

  The methods for identifying an individual are, for example, fingerprint authentication, vein shape authentication, iris pattern authentication, a card possessed by a person and a card in which information as an electronic key is recorded, or a tag possessed by a person. Thus, a tag that can identify an individual through wireless communication can be used. Thus, the present invention can be applied not only to a house used as a residence, such as a detached house or a residential space of an apartment, but also to a building that forms a workplace where several employees work.
