The storage unit 24 includes, for example, a RAM, a ROM, and the like, and stores a system program that can be executed by the server 2, various processing programs that can be executed by the system program, data that is used when these various processing programs are executed, and the like. Remember.
Specifically, the storage unit 24 stores an e-mail generation program 24a and a mail transmission control program 24b.

Based on the first to third transmission instructions received by the communication control unit 23, the e-mail generation program 24a generates an e-mail having contents according to the transmission instructions.
Specifically, when the first transmission instruction and the person identification data are received by the communication control unit 23 based on the execution of the email generation program 24a by the CPU 25, the visitor is based on the first transmission instruction and the person identification data. When the communication control unit 23 receives the second transmission instruction and the captured image data by generating an e-mail including the visitor identification text data related to the identification, the visit is performed based on the second transmission instruction and the captured image data. When an email including visitor image data relating to a person is generated and a third transmission instruction is received by the communication control unit 23, a face related to the face detection failure in the face detection process based on the third transmission instruction Generate an email containing undetectable text data.
In the above e-mail, for example, “destination” is “e-mail address” of the user's external terminal 3 registered in the storage unit 24 in advance, and “title” is “visitor contact information”. However, the present invention is not limited to these, and the “destination” and “title” can be arbitrarily changed as appropriate.

  When the communication control unit 23 receives the transmission history information in addition to the first transmission instruction and the person identification data, the CPU 25 receives the first transmission instruction, the person identification data, and the transmission history information (the first transmission instruction Based on the number of times of transmission), an email including visitor identification text data including the number of visits of the visitor is generated.

Based on the reception of the first to third transmission instructions by the communication control unit 23, the mail transmission control program 24b sends the e-mail generated by the e-mail generation process according to the transmission instruction to the external terminal by the communication control unit 23. 3 is a program for causing the CPU 25 to realize a function related to processing to be transmitted to the CPU 3.
Specifically, based on the execution of the mail transmission control program 24b by the CPU 25, an email including visitor identification text data generated by the email generation process in response to the first transmission instruction is externally transmitted by the communication control unit 23. An e-mail including visitor image data generated by the e-mail generation process in response to the second transmission instruction is transmitted to the external terminal 3 by the communication control unit 23, and the third transmission is performed. In response to the instruction, the communication control unit 23 transmits an e-mail including the face detection impossible text data generated by the e-mail generation process to the external terminal 3.

  The CPU 25 comprehensively controls each unit of the server 2 and performs various control operations according to various processing programs stored in the storage unit 24. At that time, the CPU 25 stores various processing results in the working memory of the storage unit 24 and displays the processing results on the display unit 22 as necessary.

Next, the external terminal 3 will be described with reference to FIG.
FIG. 5 is a block diagram showing a main configuration of the external terminal 3.
For example, a general mobile phone is applied to the external terminal 3 and is connected to the internal call device 12 and the server 2 via the network N so as to be able to perform information communication. Is connected to be able to make a call.
Specifically, as shown in FIG. 5, the external terminal 3 includes an operation input unit 31, a call unit 32, a display unit 33, a communication control unit 34, a storage unit 35, a CPU 36, and the like. .

  The operation input unit 31 includes a numeric keypad, various function switches (not shown), and the like, and outputs an operation signal to the CPU 36 based on an operation by a user of these numeric keys and switches.

  The calling unit 32 includes a microphone 32a, a speaker 32b, an A / D conversion unit, and a D / A conversion unit (not shown). Then, the user's transmitted voice input from the microphone 32a is A / D converted, and the transmitted voice data is output to the CPU 36, and voice data such as received voice data that is output from the CPU 36 and input. Is D / A converted, and the voice of the visitor is output from the speaker 32b.

The display unit 33 is composed of a display such as an LCD, for example, and displays various information on the display screen under the control of the CPU 36.
Specifically, the display unit 33 is an email transmitted from the server 2 and received by the communication control unit 34, that is, an email including visitor identification text data, an email including visitor image data, and face detection impossible text. Displays the contents of an email containing data.

  The communication control unit 34 includes an antenna (not shown) that transmits and receives radio signals related to incoming and outgoing calls, reception of e-mails, and the like with a radio base station (not shown), and is an instruction signal output and input from the CPU 36. Accordingly, the mobile phone communication protocol corresponding to a predetermined communication method is executed with the radio base station, and transmission / reception voice transmission / reception and data communication are executed by the communication channel set in this communication method.

  The storage unit 35 includes, for example, a RAM, a ROM, and the like, and is a system program that can be executed by the external terminal 3, various processing programs that can be executed by the system program, data that is used when these various processing programs are executed, and the like. Remember.

  The CPU 36 comprehensively controls each unit of the mobile terminal, and performs various control operations according to various processing programs stored in the storage unit 35. At that time, the CPU 36 stores various processing results in the working memory of the storage unit 35 and causes the display unit 33 to display the processing results as necessary.

Next, the operation in the intercom system 100 will be described with reference to FIGS.
First, with reference to FIG. 6, a call process between the external call device 11 and the internal call device 12 will be described.

  As shown in FIG. 6, when a visitor who visits the user operates the call button 111 a of the external communication device 11 installed at the entrance or the like (step S <b> 1), the CPU 116 of the external communication device 11 causes the imaging unit 113 to perform the operation. After the visitor is imaged (step S2), the captured image data and the calling signal generated by the imaging unit 113 are transmitted to the internal communication device 12 by the communication control unit 114 (step S3).

In the internal communication device 12, when the captured image data and the call signal transmitted from the external call device 11 are received by the communication control unit 124, the CPU 126 outputs a ringing sound from the speaker 122b according to the call signal, A captured image is displayed on the display unit 123 based on the captured image data (step S4).
Subsequently, the CPU 126 executes the response determination program 125a in the storage unit 125 to determine whether or not the user has performed a predetermined operation on the response button 121a (step S5).
Here, if it is determined that the response button 121a has been operated (step S5; YES), the CPU 126 connects the line between the external call device 11 and the internal call device 12 so that a call can be made, and the visitor and the user are connected. A call is started via the external call device 11 and the internal call device 12 (step S6).

  Thereafter, when the call between the visitor and the user ends (step S7), the CPU 126 stores call history information such as the call date and time and the call time in the history information storage area of the storage unit 125 (step S8).

  On the other hand, if it is determined in step S5 that the response button 121a is not operated (step S5; NO), in this case, it is considered that “the user is not in the building B” or “is unable to respond”. Therefore, a visitor contact process (see FIG. 7) is performed.

Below, a visitor contact process is demonstrated with reference to FIG.
FIG. 7 is a flowchart illustrating an example of an operation related to a visitor contact process.
In the following visitor contact processing, it is assumed that person identification data and person face image data of a plurality of visitors who have visited before are registered in the registration DB 125g.

  As shown in FIG. 7, the CPU 126 of the internal call device 12 executes the face detection program 125 b in the storage unit 125, and from the captured image frame transmitted from the external call device 11 and received by the communication control unit 124, A face detection process for detecting is performed (step S9).

Next, the CPU 126 determines whether or not a face has been detected in the face detection process (step S10).
If it is determined that a face has been detected (step S10; YES), the CPU 126 executes the visitor determination program 125c in the storage unit 125, and registers the face detected in the face detection process and the registration DB 125g. A visitor determination process is performed to compare and collate the person face image data that has been registered to determine whether or not the person face image data of the visitor associated with the captured image data is registered in the registration DB 125g (step S11).

If it is determined that the visitor's human face image data is not registered in the registration DB 125g (step S12; YES), the CPU 126 executes the second transmission control program 125e in the storage unit 125, and the communication control unit 124 transmits the second transmission instruction to the external terminal 3 of the electronic mail including the captured image data and the visitor image data to the server 2 via the network N (step S13).
Thereafter, the CPU 126 stores the transmitted captured image data, the transmission date and time, the transmitted captured image data name and the transmission history information such as the second transmission instruction in the history information storage area of the storage unit 125 (step S14).

On the other hand, if it is determined in step S12 that the human face image data of the visitor is registered in the registration DB 125g (step S12; NO), the CPU 126 executes the first transmission control program 125d in the storage unit 125. Then, the communication control unit 124 first transmits to the external terminal 3 an e-mail including the person identification data registered in the registration DB 125g in association with the person face image data related to the visitor and the visitor identification text data. The instruction is transmitted to the server 2 via the network N (step S15).
Thereafter, the CPU 126 stores transmission history information such as the transmission date and time, the transmitted person identification data name, and the first transmission instruction in the history information storage area of the storage unit 125 (step S16).

If it is determined in step S10 that no face has been detected (step S10), the CPU 126 acquires the captured image data generated by the imaging unit 113 of the external call device 11 to obtain the background difference method or the like. It is determined whether or not the visitor (moving object) is within the shooting range of the image pickup unit 113, that is, in the vicinity of the external communication device 11 by the inter-frame difference method or the like (step S17).
Here, if it is determined that the visitor is still in the vicinity of the external communication device 11 (step S17; YES), the CPU 126 proceeds to step S9 and controls the execution of the subsequent processing.
That is, the CPU 126 performs the face detection process (steps S9 and S10) and the visitor determination process (steps S11 and S12) again.

On the other hand, in step S17, the visitor does not exist in the vicinity of the external communication device 11, that is, the visitor judges that “the user is not in the building B” and leaves, and the external communication device 11 If it is determined not to exist in the vicinity (step S17; NO), the CPU 126 executes the third transmission control program 125f in the storage unit 125, and the communication control unit 124 detects the face related to the face detection failure. A third transmission instruction to the external terminal 3 for the electronic mail including the impossible text data is transmitted to the server 2 via the network N (step S18).
Thereafter, the process proceeds to step S <b> 16, and the CPU 126 stores transmission history information such as a transmission date and time and a third transmission instruction in the history information storage area of the storage unit 125.

  In the server 2, when the communication control unit 23 receives the first to third transmission instructions transmitted from the internal communication device 12, the CPU 25 executes the email generation program 24 a in the storage unit 24 to receive An e-mail having contents corresponding to the first to third transmission instructions is generated (step S19). Specifically, when the CPU 25 receives the first transmission instruction and the person identification data, the CPU 25 generates an e-mail including visitor identification text data related to the visitor identification, and also outputs the second transmission instruction and the captured image data. When received, an e-mail including visitor image data relating to the visitor is generated, and upon receiving a third transmission instruction, an e-mail including face detection impossible text data related to face detection disabled in the face detection process is generated. To do.

  Thereafter, the CPU 25 executes the mail transmission control program 24b in the storage unit 24, and the communication control unit 23 sends an email corresponding to the first to third transmission instructions generated in the email generation process to the network N. To the external terminal 3 (step S20).

In the external terminal 3, when the communication control unit 34 receives the electronic mail transmitted from the server 2, the CPU 36 includes the electronic mail, that is, the electronic mail including the visitor identification text data and the visitor image data. The contents of the e-mail and the e-mail including the face detection impossible text data are displayed on the display screen of the display unit 33. That is, when an e-mail including visitor identification text data is received on the display unit 33, the person identification data relating to the visitor is displayed in text, and when an e-mail including visitor image data is received. When the captured image data of the visitor is displayed and an e-mail including face detection impossible text data is received, the fact that face detection is impossible is displayed in text.
As a result, the user is a person who has visited on the display screen of the display unit 33 of the external terminal 3, and the visitor has visited before or is the person who has visited for the first time. Can be recognized.

As described above, according to the intercom system 100 of the present embodiment, when the user is absent, that is, when there is no response to the call from the external call device 11, the internal call device 12 The face detected by the face detection process is compared with the human face image data registered in the registration DB 125g based on the picked-up image data picked up and generated by the image pickup unit 113, and the person's face of the visitor is compared. It is determined whether or not the image data is registered in the registration DB 125g. If the visitor's person face image data is registered, the visit is performed based on the person identification data associated with the person face image data. A first transmission instruction to the external terminal 3 of the electronic mail including the visitor identification text data relating to the identification of the visitor is transmitted to the server 2. Further, when a face is not detected in the face detection process, a third transmission instruction to the external terminal 3 of an e-mail including face detection impossible text data related to face detection failure is transmitted to the server 2.
That is, instead of the captured image data for recognizing the visitor, an e-mail transmission instruction including text data such as visitor identification text data and face detection impossible text data is transmitted from the internal communication device 12 to the server 2, Since an e-mail including text data is transmitted from the server 2 to the external terminal 3, data communication between the interphone 1 and the server 2 and between the server 2 and the external terminal 3 as compared with the case where the captured image data is transmitted. Since the amount can be reduced, an increase in the amount of data communication can be suppressed.
On the other hand, when the visitor's person face image data is not registered, the internal call device 12 performs the second e-mail for the external terminal 3 including the visitor image data relating to the visitor based on the captured image data. By transmitting the transmission instruction to the server 2, the user can recognize who the visitor is by visually recognizing the image related to the visitor image data.
Thus, the visitor can be confirmed by the visitor identification text data and the visitor image data, and the presence of the visitor can be recognized by the face detection impossible text data. Usability can be improved.
In particular, when a user wants to respond to a conversation after recognizing a visitor, the external call device 11 and the external terminal 3 are connected so as to be able to make a call using the VoIP technology of the internal call device 12 to make a call with the visitor in real time. It is possible to provide an interphone system 100 that is more convenient to use.

In addition, when the history information storage area of the storage unit 125 of the internal communication device 12 of the interphone 1 stores transmission history information related to a visitor whose personal identification data is determined to be registered in the registration DB 125g. The first transmission instruction to the external terminal 3 of the e-mail including the person identification data, the number of transmissions of the first transmission instruction so far, and the visitor identification text data including the number of visits of the visitor is transmitted to the server 2. Then, since the server 2 transmits an e-mail including visitor identification text data including the visit number of the visitor to the external terminal 3, the importance of the visit purpose of the visitor is recognized by the visit number of the visitor. Can do. That is, for example, a visiting salesperson who has not even registered his / her name visits many times, and although it is not particularly important, personal identification data such as name and address is registered. In the case of such a deeply related visitor, it is assumed that the visitor has a certain purpose and is therefore highly important.
In such a case, after the user recognizes the importance of the visit purpose of the visitor, the external call device 11 and the external terminal 3 are connected to be able to make a call by using the VoIP technology of the internal call device 12, and the visit is made. You can also talk to the person in real time.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the above embodiment, the external call device 11 includes a requirement accepting unit that accepts a visitor's requirement, and the visitor includes the requirement accepted by the communication control unit 124 of the internal call device 12 by the requirement accepting unit. A first transmission instruction of the identification text data to the external terminal 3 may be transmitted to the server 2.
That is, when the person identification data is registered in the registration DB 125g, the person has visited at least once. Such requirement data is transmitted to the server 2. Specifically, after step S12 in FIG. 7, after the external call device 11 executes the requirement acceptance process for accepting the visitor's requirement, the internal call device 12 acquires the requirement accepted in the requirement acceptance process, A first transmission instruction to the external terminal 3 of visitor identification text data including the accepted requirements is transmitted to the server 2.

  Note that the requirement receiving means may be any device configured to be able to receive visitor requirements. For example, the requirement receiving means analyzes voice collected by the microphone 112a and converts it into character data. The requirement may be specified according to the voice emitted from the visitor according to the voice guidance emitted from the speaker 112b, or the display unit provided with the touch pad on the external communication device 11 (Not shown) may be provided, and requirements may be selected and input using the touchpad.

  As a result, even if the user cannot make a call with the visitor in real time, the requirements of the visitor can be grasped. You can also get in touch with the person. In this way, the intercom system 100 that is more convenient to use can be provided.

Further, in the configuration including the above requirement receiving means, it may be configured to determine whether or not to transmit the requirement to the user by e-mail according to the input requirement.
That is, for example, in the case of a requirement that does not require urgency, such as when a visiting salesperson visits, it is not necessary to notify the user immediately by e-mail, while the courier requires a redelivery time for the courier service. This is because it is necessary to notify the designated time in the case of a requirement in which the time is designated, such as when it is left as.

Further, in the above embodiment, the face detection process and the determination of whether or not the person's face image data of the visitor is registered in the registration DB 125g are made when the user is absent in the room and there is no response to the call. However, the present invention is not limited to this, and determination may be made regardless of whether or not there is a response to the call.
That is, even when the user is in the room, when the user is not in the vicinity of the internal call device 12 or when the user cannot move to the vicinity of the internal call device 12, or the presence of the visitor without hearing the ringing tone When it cannot be recognized, the visitor's face displayed on the display unit 123 cannot be confirmed, so that the visitor identification text data or the visitor image data is displayed on a mobile terminal such as a mobile phone carried by the user. By sending an e-mail containing, it is possible to confirm the visitor and the presence of the visitor.

  In the above embodiment, the image capturing unit 113 of the external communication device 11 continuously captures a visitor and generates a plurality of image frames. Is not limited to this, and the captured image data of the visitor may be generated at least when the call button 111a is operated.

Furthermore, in the above embodiment, the internal communication device 12 is configured to transmit the third transmission instruction to the external terminal 3 of the face detection impossible text data to the server 2, but the face cannot be detected by the face detection process. In this case, it is not always necessary to transmit the third transmission instruction, and whether or not to transmit the third transmission instruction can be arbitrarily changed as appropriate.
That is, when the third transmission instruction is not transmitted, the amount of data communication between the intercom 1 and the server 2 and between the server 2 and the external terminal 3 can be further reduced.

  In the above embodiment, the human face image data is registered in the registration DB 125g. However, it is not always necessary to register the human face image data, and the human image data related to an image other than the human face. May be registered, and a visitor may be specified using the person image data.

  In addition, in the above embodiment, the face detection process and the visitor determination process are performed by the internal communication device 12, but the present invention is not limited to this, and the external communication device 11 performs the face detection process and the visitor determination process. Also good. That is, the registration DB is stored in the storage unit 115 of the external call device 11, and the face detection process and the visitor determination process are performed based on the person face image data and person image data registered in the registration DB. Also good.

Furthermore, in the above embodiment, the storage unit 125 of the internal call device 12 stores the call history information such as the call date and time, the call time, the transmission history information related to the first transmission instruction, the captured image data, and the second transmission instruction. The history information such as the transmission history information and the transmission history information related to the third transmission instruction is stored, but as long as at least the transmission history information related to the first transmission instruction is stored, the number of visits of the visitor An e-mail including visitor identification text data including can be transmitted to the external terminal 3.
The history information as described above is not necessarily stored in the storage unit 125 of the internal call device 12, and whether or not the history information is recorded can be arbitrarily changed as appropriate.

In addition, the configuration of the intercom system 100 in the above embodiment is an example and is not limited thereto. For example, in the above-described embodiment, the external call device 11 and the internal call device 12 constituting the interphone 1 are connected by wire using a predetermined communication cable, but may be wirelessly connected.
Furthermore, although the intercom system 100 including the interphone 1 is illustrated as the visitor communication system, the present invention is not limited to this, and any system may be used as long as it is a system for making a contact about the visitor.

  In the above embodiment, a mobile phone is exemplified as the external terminal 3. However, the present invention is not limited to this, and any external device 3 can be used as long as it can receive an e-mail transmitted from the server 2. Also good. That is, for example, any device such as a PC or a portable information terminal may be used.

  In addition, it is needless to say that other specific detailed structures can be appropriately changed.
