  FIG. 5 is a diagram showing the merchant-related visitor response information 20 a stored in the storage unit 79. The merchant-related visitor response information 20 a that is the first visitor resident-related information is included in the visitor response information 20. The trader-related visitor response information 20 a includes trader-related response information 21, resident information 25, and visitor information 63. 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. Voice information including the voice of the person 12 is included. The name may be the name of the visitor 12, but in the trader-related visitor response information 20 a shown in FIG. 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 resident information 25 is information representing the resident who lives in the residence 18, and, for example, five residents of the residents A to E are shown. For example, the resident A is the grandfather, the resident B is the father, the resident C is the mother, the resident D is the eldest son, and the resident E is the eldest daughter. A black circle attached to each resident indicates that the resident is associated with the visitor 12 indicated in the same row, and indicates that the response content indicated by the response information 21 is applied. Yes. Therefore, respond to the resident with the black circle with the response content indicated by the response information 21, and do not respond to the resident without the black circle. Is shown.

  The response information 21 indicates information of response contents, and is determined according to a plurality of predetermined cases and each type of the visitor 12. In the trader relation visitor response information 20a shown in FIG. 5, at least three of the types are illustrated, and each type is set as a type 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. Situation (b) is “a situation where the resident can immediately respond to the visitor 12”, and the situation (c) is “the resident is all out and the resident "Situation without". Specifically, the situation (b) is “a situation in which the resident is present in the other part of the residence 18 other than the toilet 34 and the bathroom 36” and is in a place where the resident can respond. It is.

  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. 6 is a diagram showing the friend acquaintance related visitor response information 20 b stored in the storage unit 79. The friend acquaintance related visitor response information 20 b that is the second visitor resident related information is included in the visitor response information 20. The trader-related visitor response information 20 a includes response information 21, resident information 25, and visitor information 63. In the friend acquaintance related visitor response information 20 b shown in FIG. 6, the type of the visitor 12 corresponds to the individual of the visitor 12, and the visitor information 63 includes the information of the visitor 12. The visitor information 63 shown in FIG. 6 shows information on seven visitors 12. However, the number of visitors 12 is not limited to seven, and the necessary number of visitors 12 is displayed. You can register. Further, the visitor information 63 of the friend acquaintance related visitor response information 20b shown in FIG. 6 may include the voice information of the visitor 12 acquired through the outdoor microphone 44. In the friend acquaintance related visitor response information 20b shown in FIG. 6, each visitor 12 is associated with any one of the residents, but a plurality of residences are stored in association with all the residents. May be.

  The correspondence A in the situation (a) and the correspondence B in the situation (b) are the same as the correspondences A and B in the merchant relationship visitor response information 20a shown in FIG. Correspondence C in the friend acquaintance related visitor response information 20b shown in FIG. 6 includes the correspondence that the visitor 12 contacts the mobile phone. The response information 21 stored in the response information storage unit 13 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, but the correspondence C in the friend acquaintance related visitor response information 20b shown in FIG. The voice information acquired via the mobile phone is transferred to the mobile phone so that the mobile phone can make a call. The correspondence C includes a plurality of specific correspondences C1, C2,..., Cn (n is a natural number), and each specific correspondence Ci (i is a natural number; 1 ≦ i ≦ n) Is associated with the information of the person 12. The same correspondence Ci may be associated with a plurality of visitors 12. Although not shown in FIG. 5 and FIG. 6, the voice information that correspondence D is “I am away now. If there is a business, please tell me your name and business after a beeping sound.” It is also possible to deal with response information 21 including character information.

  FIG. 7 is a flowchart showing the steps of the response method to the visitor 12 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 area is an area captured by the camera 32. 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 type determination process, if it is determined in the visitor 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 type determination step, the process proceeds to step a8, and the response C2 is performed. If it is determined in the visitor type determination step that the type of the visitor 12 is the type T3, the process proceeds to step a9, and the response C3 is performed. After performing the actions A, B, 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, C1 to C3, D 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 a visitor type determination process like step a6, and performs the common response | compatibility with respect to all the visitors 12 to the condition (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. This notification may be notification by outputting sound information representing a doorbell or chime electronically stored in the storage means 79 from the speaker 69.

  When the visitor 12 visits and a visit is detected, imaging is performed by an outdoor imaging means, for example, the outdoor camera 42, 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. The visitor information 63 stores one for each type even if there are multiple visits. As one visitor information 63, a video may be stored as a moving image, but in this embodiment, the capacity of the storage unit 79 can be used more effectively by storing one still image 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.

  FIG. 8 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. As shown in FIG. 8, the temporarily recorded video is displayed to the resident, and the visitor information 63 is determined by the resident based on 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 that represents related contents in characters. Moreover, the information which 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.

  FIG. 9 is a diagram illustrating an example of a display screen of the display unit 86 when the visitor information 63 stored in the storage unit 79 in the past is displayed. As shown in FIG. 9, 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 storage unit 58 and displaying the information on the display unit 86 in response to an operation by the operation unit 74, whereby the resident is informed of the visitor information 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. 10 is a diagram illustrating an example of the visit history information 110. FIG. 11 is a diagram illustrating an example of a display screen when the display unit 86 displays the visit history information 110. 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 displays the visit of the visitor 12 as a history. It can be displayed so as to be visible.

  The visit history information 110 representing the visit history is set to include an outdoor image capturing unit, for example, an image captured by the outdoor camera 42 and an identification result by the visitor identifying unit 27. As shown in FIG. 11, the display unit 86 may display information on the amount of electric power obtained by solar power generation acquired via 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.

  As described above, the dwelling detection means 11 detects at least one of the position and situation of the person inside the dwelling 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.

  The intercom apparatus 10 further includes a visitor imaging unit 26 and a visitor identification unit 27. The visitor imaging means 26 images the visitor 12 and acquires a visitor image representing the captured visitor image. The visitor identifying means 27 identifies the visitor 12 by analyzing the visitor 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.

  The in-resident detection means 11 detects a person's presence position. 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.

  Further, the in-resident detection means 11 determines whether or not 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.

  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. The resident personal attribute information 113 includes resident information 25. The resident information 25 is also included in the visitor response information 20 stored in the storage unit 79. 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.

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

  The visitor identification means 27 determines the visitor 12 based on the visitor information 63 stored in the visitor storage unit 58 when the visitor 12 comes. 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. The visitor identification means 27 determines who the visitor 12 has visited among the residents based on the visitor response information 20.

  In addition, the intercom device 10 records and records video information captured by the outdoor camera 42 and audio information acquired by the outdoor microphone 44. 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 when the resident is not always one. 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 for detecting the proximity of an object using infrared rays in the vicinity of the intercom outdoor unit 39, and this sensor may detect the sensor. However, a push button 54 provided on the intercom outdoor unit 39 may be used. This is done by detecting whether or not 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. The presence position of the person at home is a position where the person can respond is that the person whose presence is detected is in a place where he / she can 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. The trader is a visitor related to the trader. 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, this 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 determined. Next, the process proceeds to step b8, and a response is made according to the content determined in step b7. 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. Residents who have been visited are given priority by notifying residents earlier than those who have not been visited, but in other embodiments, residents who have been visited by making a loud sound are used. It is good also as a structure which informs the person who has received the visit.

  In step b3, if it is determined that there is a person at home but the location of the person at home is a place where a response is not possible, 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 cannot be made, 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 steps performed on the visitor 12 in the response method to the visitor 12. 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, where it is determined whether or not there is visitor information 63 corresponding to the identification result by the visitor identification means 27. 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. A friend or acquaintance is a visitor other than the merchant and is distinguished from the merchant. If it is determined that the user is a friend or acquaintance, the process proceeds to step c7, and the visiting partner visited by the visitor 12 is specified. 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. Next, it transfers to step c19 and respond | corresponds indoors. In this case, the sound may be simply generated through the speaker 69, or the recording information based on the voice of the visitor may be output through the speaker 69. Thereafter, the process proceeds to step c10, and imaging and video storage are finished. After step c10, the process proceeds to step c1.

  As described above, the dwelling detection means 11 acquires predetermined types of information about the person whose location is detected inside the dwelling 18. 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 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.

  As a result, a person in the residence can be identified, and the response content to the visitor 12 can be changed according to the status of the identified home-staying person. For example, the response content to the visitor 12 is changed based on whether or not the person identified by the resident identification unit 111 is a resident in the residence 18 and who is the resident. can do. As a result, the safety level set in the residence 18 can be matched with the safety level required by the person in the residence 18.

  The intercom device 10 includes a visitor storage unit 58. The visitor storage unit 58 stores a visitor image captured by the visitor imaging unit 26. In addition, the visitor storage unit 58 stores the identification result of the visitor image by the visitor identification unit 27 in association with the information of at least some of the residents stored in the resident information storage unit 112.

  As a result, when the visitor 12 whose image information and the identification result by the visitor identification means 27 have already been stored in the visitor storage unit 58 has visited, the visitor 12 visits any of the residents. It can be determined whether or not the person 12 is. Therefore, the response content to the visitor 12 can be changed depending on whether or not the resident who is visited is at home, and if the resident who is visited is at home, The response content to the visitor 12 can be changed according to the situation of the resident who is present. Furthermore, according to the visitor 12, it becomes possible to set a priority order to a home person, and it becomes possible to perform notification according to the priority order.

  The intercom device 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.

  This makes it possible to give notification to a home visitor who has received a visit earlier than notification to other home stayers other than the home visitor who has received a visit among a plurality of home visitors. Therefore, the response content for the visitor 12 can be a response content that is preferable for both the visitor 12 and the home-stayed person.

  Furthermore, the predetermined type of information acquired by the in-resident detection means 11 includes image information. The in-housing detection means 11 includes one or a plurality of indoor imaging units 22 and a person presence determination unit 24. The one or more indoor imaging units 22 capture images at a plurality of positions inside the residence 18 and acquire indoor images. The person presence determination unit 24 analyzes the indoor image and determines whether or not a person is captured at each position inside the residence 18. 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.

  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.

  In addition, 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.

  Therefore, this 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, 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.

  The in-resident detection means 11 further 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 place according to the measurement result of the flow rate measurement unit. Therefore, 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.

  In FIG. 7 and FIG. 12, the dwelling detection means 11 exemplifies the case where the person's location in the dwelling 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 a person exists, the present invention is not limited to the case where the person is present in 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.

  Furthermore, the intercom apparatus 10 further includes a sound volume measurement information acquisition unit 89. The sound volume measurement information acquisition means 89 that is a sound volume measurement means includes a sound volume measuring device. The volume measuring device is constituted by, for example, a microphone and a volume measuring circuit, and is arranged in each room 28 one by one. The volume measuring circuit measures the volume of the sound collected by the microphone and sends volume information representing the measured volume to the control means 17. The control unit 17 determines the volume of the chime output from the speaker 69 according to the volume of each room 28 indicated by the volume information received from the volume measurement information acquisition unit 89, and outputs the chime from the speaker 69 at the determined volume. . A chime is a ringing sound.

  FIG. 14 is a diagram illustrating an example of the sound control information 31. The sound control information 31 is information set in the setting storage unit 78 in advance by operating the operation unit 74. The sound control information 31 includes “No” column 311, “identification name” column 312, “name” column 313, “reading” column 314, “volume to be increased (S 3)” column 315, and “ringing sound pattern” column 316. Contains items.

  The “No” column 311 is a column indicating a number assigned to a registered resident. The “identification name” column 312 is a column indicating an identification name that is identification information for identifying a resident. The “name” column 313 is a column indicating the name of the resident. The “reading” column 314 is a column indicating how to read the name in katakana. The “Volume to be increased (S3)” column 315 is a column indicating an increased volume in decibels for increasing the volume. The “ringing sound pattern” column 316 is a column indicating a ringing sound pattern that is a chime pattern.

  In the example shown in FIG. 1 resident A has the name “Hideki Sato”, the reading is “Hideki Sato”, the volume to be raised is “+6 dB”, and the ringing sound pattern is “A”. No. The resident B of No. 2 has the name “Koichi Sato”, the reading “Sato Kouichi”, the volume to be raised “+4.5 dB”, and the ringing sound pattern “B”. No. The resident C of No. 3 has the name “Ryoko Sato”, the reading “Sato Ryoko”, the volume to be raised “+3.5 dB”, and the ringing sound pattern “C”. No. Resident D of No. 4 has the name “Sato Keisuke”, the reading “Sato Keisuke”, the volume to be raised “+1.5 dB”, and the ringing sound pattern “D”. No. The resident E of No. 5 has the name “Eri Sato”, the reading is “Satoueri”, the volume to be raised is “+1.5 dB”, and the ringing sound pattern is “E”.

  The volume level to be increased, which is a predetermined increase volume, is set large for a person with a long ear, such as an elderly person, and small for a person with a good ear, such as a young person.

  FIG. 15 is a flowchart illustrating a processing procedure of the notification strengthening process after the processing B for the friend acquaintance relationship. The notification strengthening process is a process for surely notifying the resident that there is a visitor 12. The notification enhancement process after the corresponding action B process related to the friend acquaintance is a process included in the execution of the corresponding action B process in step b8 shown in FIG. After the process described in step b8 shown in FIG. 12 is executed, the process proceeds to step e1.

  In the case of the notification enhancement process shown in FIG. 15, in step b2 shown in FIG. 12, the control means 17 designates the resident associated with the visitor 12 identified by the visitor identification means 27 as the friend shown in FIG. It specifies based on the acquaintance related visitor response information 20b, and determines whether the specified resident exists in the dwelling. In the case of a visitor 12 who is friends and acquaintances, any one resident is associated with the visitor 12. When the specified resident exists in the dwelling, the process proceeds to step b3, and when the specified resident does not exist in the dwelling, the process proceeds to step b14. In step b3 shown in FIG. 12, the control means 17 determines whether or not the specified location of the resident is a responsive position. When the identified resident's presence position is a responsive position, the identified resident is set as the target resident, and the process proceeds to step b4. When the identified resident's presence position is not a responsive position, step b9 Proceed to

  In step e1, the control means 17 measures the volume of the room 28 where the target resident is present. Specifically, the control means 17 which is a room specifying means specifies the room 28 where the target resident is present based on the identification result of the resident identification means 111, and measures the sound volume installed in the specified room 28. The volume indicated by the volume information received from the device is “S2 *”. “*” Indicates which of the residents indicated by the identification name shown in the “identification name” column 312 of the sound control information 31 shown in FIG. For example, if “*” is “A”, “S2 *” indicates the volume of the resident A.

In step e2, the control means 17 determines ringing volume S1 by Formula (1).
S1 = S2 * + S3 * (1)

  “S3 *” is an increase volume of the target resident among the increase volumes indicated in the “volume to be increased (S3)” column 315 of the sound control information 31 illustrated in FIG.

  In the “volume to be increased (S3)” column 315 shown in FIG. 14, the increased volume is shown in units of “dB”. Therefore, the increased volume is set to the “volume to be increased (S3)” column 315. Is a value obtained by subtracting the measured volume from the value obtained by multiplying the ratio represented by the “dB” value shown in FIG. For example, when the resident is “resident A”, since the ratio shown in the “volume to be increased (S3)” column 315 is “6 dB”, the ringing volume S1 is double the measured volume S2. It is necessary to make it the volume. Therefore, the increased volume S3 is a volume obtained by subtracting the measured volume S2 from the volume obtained by doubling the measured volume S2.

  In step e3, the control means 17 determines whether it is less than the reference maximum ringing volume S0. The reference maximum ringing volume S0 is set to the maximum volume that can be output from the speaker 69, for example, but may be configured to be set by the operation unit 74. When S0> S1, it is determined that it is less than the reference maximum ringing volume S0, and the process proceeds to step e4. When S0> S1, it is determined that it is not less than the reference maximum ringing volume S0, and the process proceeds to step e10.

  In step e4, the control means 17 sounds with the sound volume S1. Specifically, the control means 17 outputs from the speaker 69 a chime that rings at the ring volume S1. In step e5, the control means 17 starts measuring the elapsed time after the start of ringing. In step e6, the control means 17 determines whether or not a certain time has elapsed. Specifically, the control means 17 measures the elapsed time by a timer (not shown) included in the indoor unit 65, and determines whether or not a predetermined time, for example, 20 seconds has elapsed after the start of ringing. The fixed time is configured to be settable from the operation unit 74. When the fixed time has elapsed, the process proceeds to step e7, and when the fixed time has not elapsed, the process returns to step e6.

  In step e7, the control means 17 confirms the location of the target resident. Specifically, the control means 17 instructs the person presence determination unit 24 to check whether the target resident is present in the room 28 identified in step e1. The person presence determination unit 24 images the room by the indoor imaging unit 22 installed in the room 28 specified in step e1, and whether the target resident exists in the specified room 28 based on the captured indoor image. Determine whether. The person presence determination unit 24 sends the determination result to the control means 17.

  In step e8, the control means 17 determines whether a resident exists. When the determination result received from the person presence determination unit 24 indicates that the target resident is present in the specified room 28, the control unit 17 determines that the resident is present and proceeds to step e9. When the determination result received from the person presence determination unit 24 indicates that there is no target resident in the specified room 28, no resident exists, that is, the target resident corresponds to the visitor 12. Therefore, it is determined that the user has moved to the entrance 51, the notification strengthening process after the friend B acquaintance corresponding action B process is terminated, and the process returns to step b1 shown in FIG.

  In step e9, the control means 17 changes the ring pattern and makes it ring. Specifically, the control means 17 sets the chime ringing pattern that rings at the ringing volume S1 among the ringing patterns shown in the “ringing sound pattern” column 316 of the sound control information 31 shown in FIG. The chime changed to the person's ringing pattern is output from the speaker 69, the notification strengthening process after the process B corresponding to the friend acquaintance is terminated, and the process returns to step b1 shown in FIG. For example, the chime “ping pong” ringing pattern is changed to a “ping pong pong pong” ringing pattern indicating a higher degree of urgency.

  In step e10, the control means 17 sounds at the reference maximum sound volume S0. That is, the control means 17 outputs a chime that rings at the reference maximum ringing volume S0 from the speaker 69, and proceeds to step e5.

  FIG. 16 is a flowchart showing a processing procedure of the notification enhancement processing after the processing B for the business related to the business. The notification strengthening process after the trader-related action B process related to the trader is a process included in the execution of the trader-compatible action B process in step b6 shown in FIG. After the process described in step b6 shown in FIG. 12 is executed, the process proceeds to step f1.

  In the case of the notification enhancement process shown in FIG. 16, in step b2 shown in FIG. 12, the control means 17 selects the resident associated with the visitor 12 identified by the visitor identification means 27 as the trader shown in FIG. It specifies based on the related visitor response information 20a, and determines whether the specified resident exists in a residence. In the case of the visitor 12 related to the trader, the resident associated with the visitor 12 is not necessarily one. When at least one of the identified residents is present in the residence, the process proceeds to step b3, and when all the identified residents are not present in the residence, the process proceeds to step b14. In step b3 shown in FIG. 12, the control means 17 determines whether or not the position of the resident who is at home among the specified resident is a responsive position. Hereinafter, a resident who is at home among the specified resident is referred to as a specified resident. When the location of at least one of the identified at-homers is a position where response is possible, the home-at-home that is the available location among the identified at-homes is set as the target resident, and the process proceeds to step b4. When all the present positions of the identified home-stayers are not responsive positions, the process proceeds to step b9.

  In step f1, the control means 17 measures the volume of the room 28 where the target resident is present. Specifically, the control means 17 specifies the room 28 where the target resident is present based on the identification result of the resident identification means 111, and the volume received from the volume measuring device installed in the identified room 28. The volume indicated by the information is “S2a”, “S2b”,.

In step f2, the control means 17 calculates a ringing volume. Specifically, the ringing sound volume is determined for each target resident by Equation (2).
S1a = S2a + S3a, S1b = S2b + S3b, (2)

  The lowercase letters “a”, “b”,... Appended to “S1”, “S2”, “S3” are subscripts for identifying the target resident. For example, “S2a” Is the volume of the room 28 of the resident B, and “S2b” is the volume of the room 28 of the resident C.

In step f3, the control means 17 determines the maximum ringing volume S1max by the equation (3).
S1max = max (S1a, S1b,...) (3)

  max (S1a, S1b,...) is a volume having the maximum value among the ringing volumes S1a, S1b,.

  In step f4, the control means 17 determines whether it is less than the reference maximum ringing volume S0. When S0> S1max, it is determined that it is less than the reference maximum ringing volume S0, and the process proceeds to step f5. When S0> S1max is not determined, it is determined that it is not less than the reference maximum ringing volume S0, and the process proceeds to step f11. Steps f5 to f8 and f11 are the same as steps e4 to e7 and e10 shown in FIG. 15, respectively, and a description thereof will be omitted to avoid duplication.

  In step f9, the control means 17 determines whether all the residents are present. When the determination result received from the person presence determination unit 24 indicates that all the target residents are present in the room 28 specified in step f1, the control means 17 determines that there are residents, Proceed to step f10. When the determination result received from the person presence determination unit 24 indicates that at least one of the target residents is not present in the specified room 28, there is no resident, that is, among the target residents. It is determined that at least one person has moved to the entrance 51 in order to respond to the visitor 12, the notification enhancement process after the corresponding action B process of the friend acquaintance relationship is terminated, and the process returns to step b1 shown in FIG.

  In step f10, the control means 17 changes the sound pattern and makes it sound. Specifically, the control means 17 sets the chime ringing pattern that rings at the maximum ringing volume S1max among the ringing patterns shown in the “ringing sound pattern” column 316 of the sound control information 31 shown in FIG. The chime changed to the resident's ringing pattern with the volume set to the maximum ringing volume S1max is output from the speaker 69, and the notification strengthening process after the dealer-related dealer action B process is terminated, as shown in FIG. Return to step b1.

  In the above-described embodiment, the target resident is specified and the volume of the room where the specified resident is present is measured. However, the volume of all rooms may be measured without specifying the target resident. In this case, an increase volume and ringing pattern may be set for each room, not for the resident.

  As described above, the in-resident detection unit 11 detects the presence of a person inside the residence 18 including the plurality of rooms 28. The response information storage unit 13 stores a plurality of response information 21 representing a plurality of response contents different from each other with respect to the visitor 12 visiting the residence 18. The output means 16 outputs one or a plurality of response contents represented by one or a plurality of response information 21 of the plurality of response information 21 to the outside of the residence 18 to the visitor 12. The push button 54 detects that the visitor 12 has visited. The speaker 69 outputs a chime for notifying that the visitor 12 has visited. The volume measurement information acquisition unit 89 measures the volume of the sound generated in each room 28. The control means 17 specifies the room 28 where the person whose presence is detected by the in-housing detection means 11 is present. Then, when it is detected by the push button 54 that the visitor 12 has visited, the control means 17 is based on the detection result by the in-resident detection means 11 and a plurality of response information 21 stored in the response information storage unit 13. One or a plurality of response information 21 is selected from the above, the response content represented by the selected response information 21 is output to the output means 16, and the volume of the room 28 specified by the control means 17 is further set to the volume measurement information acquisition means 89. The chime is output by the speaker 69 at a ringing volume that exceeds the measured volume. Therefore, the response content to the visitor can be set to the response content according to the situation of the home-staying home, and the resident can be more surely notified that there is the visitor 12.

  Furthermore, the dwelling detection means 11 determines whether or not the person whose presence is detected in the dwelling 18 is in a place where it can be accommodated. Then, the control unit 17 causes the speaker 69 to output a chime with the ringing volume when the in-dwelling detection unit 11 determines that the person whose presence is detected inside the dwelling 18 is in a place where it can respond. Therefore, the resident can be more surely notified that there is the visitor 12 only when the person whose presence is detected inside the residence 18 is in a place where he / she can respond.

  Furthermore, the control means 17 outputs a chime by the speaker 69 with the resident who exists in the room 28 specified by the control means 17 when it is detected by the push button 54 that the visitor 12 has visited. When the resident who is present in the room 28 specified by the control means 17 matches with the speaker 69, the chime is output by the speaker 69 with a ringing pattern different from the ringing pattern when the chime is output by the speaker 69 at the ringing volume. Output. Therefore, even if the chime is output, when the resident does not move from the room 28, the resident can be more surely notified that there is a visitor 12.

  Furthermore, the visitor imaging means 26 images the visitor 12 and acquires a visitor image representing the image of the captured visitor 12. The visitor identification unit 27 identifies the visitor 12 by analyzing the visitor image acquired by the visitor imaging unit 26. The storage means 79 stores visitor response information 20 representing the resident associated with each visitor 12 for each visitor 12. Then, the control means 17 specifies a resident associated with the visitor 12 identified by the visitor identification means 27 based on the visitor response information 20 stored in the storage means 79, and among the identified residents The volume measurement information acquisition unit 89 measures the volume of the room 28 where the resident whose presence is detected by the in-resident detection unit 11 is present. Therefore, it is possible to notify the resident more surely that only the resident who is associated with the visitor 12 has the visitor 12.

  Furthermore, the visitor response information 20 stored in the storage unit 79 includes the trader-related visitor response information 20a that associates the trader-related visitor 12 with at least one of the residents, and the visitor 12 other than the trader relation. And friend acquaintance related visitor response information 20b for associating any one of the residents. Thus, if visitor 12 is a merchant, visitor 12 is associated with at least one resident associated with the merchant, and if visitor 12 is a friend acquaintance, visitor 12 is associated with the one resident associated with the friend or acquaintance. It is possible to inform the resident more reliably that there is.

  Further, since the ringing volume that exceeds the measured volume is a ringing volume obtained by adding a predetermined increase volume to the measured volume, the ringing volume that exceeds the measured volume can be calculated by simple calculation. Can do.

  Further, the resident identification unit 111 identifies a resident present in the room specified by the control unit 17 among the persons detected by the in-resident detection unit 11. The predetermined increase volume is an increase volume set for each resident identified by the resident identification means 111. Then, the control unit 17 causes the speaker 69 to output the ringing sound at the maximum ringing volume that is the maximum volume among the volumes obtained by adding the predetermined increase volume to the measured volume. That is, since the ringing sound is generated with the maximum ringing volume, it is possible to more reliably notify the resident that there is a visitor.
