(Indoor unit state transition example)
An example of state transition in the indoor unit 200 according to the present embodiment will be described with reference to FIG. FIG. 2 is a schematic diagram illustrating an example of state transition in the indoor unit 200.

  The example 301 shows the state of the indoor unit 200 before the visitor operates the call button 110 of the outdoor unit 100. In the illustrated example, the indoor unit 200 includes a display unit 210 at the center, and a call key 240 and an indoor microphone 230 are disposed below the display unit 210. In addition, an automatic answering key 250 is provided at the lower right of the housing of the indoor unit 200. In the example 301, nothing is displayed on the display unit 210, and the indoor microphone 230, the call key 240, and the automatic answering key 250 are disabled.

  When the visitor operates the call button 110 of the outdoor unit 100, the indoor unit 200 changes from the state shown in the example 301 to the state shown in the example 302. In the example 302, the visitor image acquired by the visitor information acquisition unit 282 using the camera 120 is displayed on the display unit 210, and the voice of the visitor acquired using the microphone 130 is not illustrated in the indoor speaker 220 (not shown). Is output from. From the video of the visitor, or from the video and audio, the responder can determine whether to talk to the visitor or perform an automatic response.

  Example 303 shows a state after the responder operates the call key 240 with respect to the state of Example 302. When the respondent operates the call key 240, the input control unit 284 acquires the voice uttered by the responder using the indoor microphone 230. The reception output unit 285 outputs the voice uttered by the response person from the outdoor speaker of the outdoor unit 100. As a result, since the voice uttered by the visitor is output from the indoor speaker 220 and the voice uttered by the responder is output from the outdoor speaker 140, a call can be made between the visitor and the respondent. Become. Based on the content of the call with the visitor, the responder can invite the visitor into a building, for example.

  The example 304 shows a state after the responder operates (presses) the automatic response key 250 with respect to the state of the example 302. When the responder operates the automatic response key 250, the input control unit 284 instructs the response output unit 285 to output the first response message from the outdoor speaker 140. When the first reception message is output from the outdoor speaker 140, the visitor utters his / her identity and the purpose of the visit to the microphone 130 according to the first reception message. Since the voice about the visitor's identity and the purpose of the visitor uttered is output from the indoor speaker 220, the respondent can confirm the visitor's identity and the purpose of the visit.

  Further, in Example 304, a response selection key 260 is displayed on the display unit 210, and a user can select and operate (press) a desired key.

  Example 305 shows a state after the responder operates (presses) the reception selection key 260 with respect to the state of Example 304. When the response person operates the response selection key 260, the input control unit 284 instructs the response output unit 285 to acquire the second response message corresponding to the previously operated key from the response message 271 and output it from the outdoor speaker 140. To do. The visitor can confirm the second reception message output from the outdoor speaker 140 and grasp that the visit was not accepted.

  Note that the call key 240 can be operated in any state of Examples 302 to 305. For example, by outputting the first response message from the outdoor speaker 140 in Example 304 and pressing the call key 240, the responder may be able to talk to the visitor as shown in Example 303.

(Responding flow)
With reference to FIG. 3, a description will be given of a flow in which a visitor responds to a visitor using the intercom device 1 according to the present embodiment. FIG. 3 is a schematic diagram showing an outline of the flow of the visitor to the visitor using the intercom device 1, and FIG. 3 (a) shows that the visitor operates the call button 110 to answer the visitor. It shows the flow to start. FIG. 3B shows a flow after the response shown in FIG. 3A, in which the responder operates various keys to perform automatic reception.

  FIG. 3A shows that when a visitor operates the call button 110 of the outdoor unit 100, an image of the visitor is displayed on the indoor unit 200, and the attendant notices the visit. In other words, (a) of FIG. 3 shows a flow of transition of the state of the indoor unit 200 from the example 301 to the example 302 in FIG. 2 from another viewpoint.

  FIG. 3B shows a flow in which, after FIG. 3A, the responder operates the automatic response key 250 and the response selection key 260 of the indoor unit 200 in order, and ends the response without talking to the visitor. Show. As shown in FIG. 3A, the respondent confirms the visitor's video on the display unit 210. For example, if the visitor is unfamiliar and does not want to make a direct call with the visitor, the attendant operates the automatic answer key 250 to the outdoor speaker 140 of the outdoor unit 100, and the first answer message “automatic customer service system”. Please tell me your name and business. " After confirming the first response message, the visitor speaks about his / her identity and the purpose of the visit. In the example shown in the figure, the visitor utters the purpose of the visit (= religion solicitation), saying, “Would you like to join the school? Call me later.” Since the purpose of the visit uttered by the visitor is output as audio from the indoor speaker 220 of the indoor unit 200, the respondent operates the reception selection key 260 displayed on the display unit 210 to select the second reception message. . In the illustrated example, the respondent has selected “I am not interested” as the second response message. Thereafter, when the second response message “I am not interested” is output from the outdoor speaker 140 of the outdoor unit 100, the visitor can know that his / her visit has not been accepted.

  Depending on the assumption that the recording function is provided in the intercom device 1 depending on the visitor, it is possible to utter the purpose of the visit etc. in response to the automatic response and make the contact person contact the caller. There is sex. Therefore, for example, the intercom device 1 may output a third response message indicating that the visitor's utterances in a series of responses could not be recorded after a lapse of a predetermined time from the output of the second response message. The second response message may be anything that indicates that the visitor's utterance has not been recorded, such as “The recording time limit has been reached and cannot be recorded.” Good.

  In addition, it is conceivable that a visitor operates the call button 110 a plurality of times on the assumption that the person using the answering machine is used. Therefore, for example, the control unit 280 of the intercom device 1 has output the first response message within a predetermined waiting time by the visitor identified from the video acquired by the visitor information acquisition unit 282 or the video and audio. It may be determined whether or not a visitor is present. If the visitor has already output the first response message within the predetermined waiting time, the response output unit 285 obtains a fourth response message from the response message 271 indicating that no continuous operation should be performed. May be output from the outdoor speaker 140.

(Process flow)
The flow of processing executed by the intercom device 1 in this embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of a flow of processing executed by the intercom device 1. Although not described in the flowchart, by pressing the call key 240 of the indoor unit 200 at an arbitrary timing, the responder can interrupt the series of processes at any time and talk with the visitor.

  First, the visit detection unit 281 of the indoor unit 200 determines whether or not the call button 110 of the outdoor unit 100 has been pressed by the visitor (S1). When it is determined that the call button 110 has been pressed by the visitor (YES in S1), the visitor information acquisition unit 282 of the indoor unit 200 acquires the visitor's video using the camera 120 of the outdoor unit 100. Then, the output control unit 283 of the indoor unit 200 displays the visitor image acquired by the visitor information acquisition unit 282 on the display unit 210 (S2: visitor information acquisition step, output control step). At this time, the visitor information acquisition unit 282 acquires a visitor's voice using the microphone 130, and the output control unit 283 outputs the visitor's voice from the indoor speaker 220.

  After S2, the input control unit 284 of the indoor unit 200 determines whether or not the automatic answering key 250 has been pressed (S3). When it is determined that the button has been pressed (YES in S3), the reception output unit 285 acquires the first reception message from the reception message 271 in the storage unit 270 and outputs the first reception message from the outdoor speaker 140 of the outdoor unit 100 (S4: reception output step). . Thereafter, the process proceeds to S5. On the other hand, when it determines with not having been pressed (it is NO at S3), the intercom apparatus 1 complete | finishes a series of processes after progress of predetermined time.

  In S5, the input control unit 284 of the indoor unit 200 determines whether or not the reception selection key 260 has been pressed (S5). The reception output unit 285 acquires the second reception message from the reception message 271 in the storage unit 270 and outputs it from the outdoor speaker 140 of the outdoor unit 100 (S6). Thereafter, the process proceeds to S7. On the other hand, if it is determined that the button has not been pressed (NO in S5), the process directly proceeds to S7.

  In S7, the control unit 280 of the indoor unit 200 determines whether or not a predetermined time has elapsed (S7). If it is determined that the predetermined time has elapsed (YES in S7), the reception output unit 285 acquires the third reception message from the reception message 271 in the storage unit 270 and outputs it from the outdoor speaker 140 of the outdoor unit 100 (S8). Thereafter, the series of processing is terminated.

  Through the above processing, the intercom apparatus 1 according to the present embodiment can display a visitor's video on the display unit 210 and output a first response message when the automatic response key 250 is operated. Thereby, for example, when the respondent does not want to talk with the visitor, it can respond while pretending to be absent. Therefore, there is an effect that it is possible to provide an intercom device with improved security for visitors.

[Embodiment 2]
A second embodiment of the present invention will be described with reference to FIG.

(Configuration of intercom device 1 and external server 300)
The configuration of the intercom apparatus 1 according to the present embodiment and the external server 300 connected to the intercom apparatus is shown in FIG. FIG. 5 is a block diagram illustrating an example of a main configuration of the intercom device 1 that cooperates with the external server 300.

  The basic configuration of the intercom device 1 is the same as that of the first embodiment. In the present embodiment, the indoor unit 200 of the intercom device 1 is connected to be communicable with one external server 300. The intercom apparatus 1 can output the first response message from the outdoor speaker 140 in the same manner as in the first embodiment, and allow the visitor to speak his / her identity and the purpose of the visit.

  In the present embodiment, for example, when it is estimated that a visitor has spoken a false feature, the intercom device 1 can output a fifth response message that causes the visitor to speak the feature again. Specifically, the intercom device 1 identifies the feature of the visitor from the speech uttered by the visitor through speech recognition. The intercom apparatus 1 estimates the visitor's identity from the face image identified by image analysis of the visitor's video. The intercom device 1 assumes that the visitor's feature identified from the voice does not match the visitor's feature estimated from the video, and that the visitor has spoken a false feature, and speaks the feature to the visitor again. The fifth response message to be output can be output from the outdoor speaker 140.

  The external server 300 is a data server that stores master data that is referred to when the indoor unit 200 executes a specific process. The external server 300 includes a server storage unit 310 and a server control unit 320, and the server storage unit 310 includes a response message 311, face data 312, and sound pattern data 313.

  The server storage unit 310 stores various data handled by the external server 300. The response message 311 may be configured to have the same content as the response message 271 provided in the indoor unit 200 of the intercom device 1, or may be configured to include more data than the response message 271. The face data 312 is master data referred to by the control unit 280 when the control unit 280 of the indoor unit 200 estimates the visitor's identity from the visitor's video. The sound pattern data 313 is master data referred to by the control unit 280 when the control unit 280 of the indoor unit 200 estimates the visitor's identity from the voice uttered by the visitor.

  The server control unit 320 controls each unit of the external server 300 in an integrated manner. When receiving an instruction to transmit various data stored in the server storage unit 310 from the indoor unit 200, the server control unit 320 acquires the corresponding data from the server storage unit 310 and transmits it.

(Flow until the feature is spoken again)
In the present embodiment, after the interphone device 1 utters the feature to the visitor, the flow of processing until the fifth response message that utters the feature again is output from the outdoor speaker 140 will be described below.

  First, the intercom apparatus 1 outputs the first response message from the outdoor speaker 140, and makes the visitor speak his / her identity and the purpose of the visit. When the visitor speaks, the control unit 280 of the indoor unit 200 of the intercom apparatus 1 identifies the feature of the visitor spoken by the visitor with respect to the first response message by voice recognition. Furthermore, the control unit 280 compares the voice uttered by the visitor with the voiceprint data 313 provided in the external server 300 to estimate the visitor's identity. The control unit 280 analyzes the image of the visitor acquired by the visitor information acquisition unit 282 and compares the image with the face data 312 provided in the external server 300 to estimate the visitor's identity.

  Thereafter, the control unit 280 determines whether the visitor's feature estimated from the voiceprint data 313 matches the feature estimated from the face data 312. If the features do not match, the controller 280 estimates that the visitor has spoken a false feature and outputs a fifth response message from the outdoor speaker 140 using the response output unit 285.

  In this way, the intercom apparatus 1 according to the present embodiment is false in the identity of the visitor uttered by the visitor using the face data 312 and the voiceprint data 313 included in one external server 300. It can be determined whether or not. And when it is estimated that the visitor spoke the false feature, the 5th reception message which makes the visitor speak the feature again can be output.

  In the above description, the intercom device 1 is configured to determine whether the identity of the visitor spoken by the visitor is false using the face data 312 and the voiceprint data 313 provided in the external server 300. . However, for example, the intercom device 1 includes face data and sound pattern data, and the interphone device 1 determines whether or not the identity of the visitor uttered by the visitor using the face data and sound pattern data included in the interphone device 1 is false. May be determined. In general, the interphone device 1 having face data and sound pattern data has an advantage that a series of processing can be performed at high speed.

  Further, the external server 300 may be configured to include information for specifying a visitor in addition to the face data 312 and the voiceprint data 313. For example, the external server 300 further includes data on uniforms of various occupations, and the control unit 280 of the indoor unit 200 analyzes the image of the visitor and specifies the type of uniform worn by the visitor.
