The mobile terminal device 10 can be connected to both the Internet network 12 and the mobile phone network 14 simultaneously. In the present embodiment, the mobile phone network 14 may be anything that can transmit voice. Further, as described later, the mobile terminal device 10 can be connected to the Internet network 12 without going through the mobile terminal network 14 and the gateway, as will be described later. The connection to the Internet network 12 here can be realized through a network such as a wireless LAN (not shown) other than the cellular phone network 14.

  The center device 16 includes a server 22 and a telephone server 24. The server 22 has the following functions, for example.

  The server 22 stores data via the Internet network 12 from the controller 30 (FIG. 2) of the household device group 20 in a database (not shown), and transmits the data to the mobile terminal device 10. At this time, the data format (format) is adjusted according to the model of the mobile terminal device 10. For image data, image size adjustment is included.

  Further, the server 22 accepts control information (command) transmitted from the mobile terminal device 10 via the Internet network 12 and transmits the control information (command) to the home device group 20.

  The telephone server 24 controls telephone notification via the mobile phone network 14 between the mobile terminal device 10 and the home device group 20. In addition, a call record in the mobile terminal device 10 and a call record in the home device group 20 are stored in the database.

  The controller 30 can be connected to the cellular phone network 14 via the splitter 32 and can be connected to the Internet network 12 via the modem 34 and the splitter 32. In communication via the Internet network 12, the controller 30 follows TCP / IP.

  In the present embodiment, data from the Internet network 12 is transmitted to the controller 30 via the ADSL / telephone network 18. However, in the ADSL / telephone network 18 as well, data from the Internet network 12 is communicated separately from voice signals for normal telephone communication. Therefore, communication via the Internet network 12 and the ADSL / telephone network 18 is referred to as communication via the Internet network 12.

  On the other hand, communication via the mobile phone network 14 is also actually via the mobile phone network 14 and the ADSL / phone network 18, but is simply referred to as communication via the mobile phone network.

  In the present embodiment, data communication according to TCP / IP is realized between the controller 30 and the interphone master unit 36 and between the controller 30 and the interphone slave unit 38.

  The controller 30 accepts the image data and the audio signal of the interphone slave unit 38 having the camera 39 installed at the entrance. The controller 30 transmits image data to the mobile terminal device 10 via the data server 22 and the Internet network 12, and transmits an audio signal to the mobile terminal device 10 via the mobile phone network 14.

  Note that transmission of image data conforms to TCP / IP as described above. Also, the transmission of audio data follows the mobile phone system. Further, in this specification, since the voice is transmitted through the cellular phone network 14, the signal is described as “voice signal” for convenience, but it may be a digital signal. Not too long.

  The audio signal from the mobile terminal device 10 is transmitted to the home device group 20 via the mobile phone network 14 and is received by the controller 30 via the splitter 32. The audio signal received by the controller 30 is reproduced from, for example, the microphone / speaker 41 of the interphone slave unit 38.

  FIG. 3 is a block diagram illustrating a configuration example of the mobile terminal device according to the present embodiment. As shown in FIG. 3, the mobile terminal device 10 according to the present embodiment includes a CPU 50, an input device 52, a display device 54, a telephone communication circuit 56, an Internet communication circuit 58, an audio processing circuit 60, a speaker 62, a microphone 64, and A memory 65 is included.

  In the present embodiment, the audio signal input via the microphone 64 is transmitted from the antenna 66 via the telephone communication circuit 56. Similarly, the audio signal received by the antenna 66 is emitted from the speaker 62 via the telephone communication circuit 56.

  In addition, control information including characters and the like operated by the input device 52 is transmitted from the antenna 68 via the Internet communication circuit 58. Also, image data received by the antenna 68 is displayed on the screen of the display device 54 via the Internet communication circuit 58. In the present embodiment, the telephone communication circuit 56 and the Internet communication circuit 58 can operate simultaneously. Thus, voice communication using the telephone communication circuit 56 and control information and image data communication using the Internet communication circuit 58 are realized simultaneously and in parallel.

  In the present embodiment, the mobile terminal device 10 accesses a predetermined URL, logs in to the server 22, and is stored in a predetermined area in the database of the server 22 in which image data from the controller 30 is stored. A program (script) that requests transmission of image data is stored in the memory 65. In the present embodiment, the mobile terminal device 10 stores a script that is a program written in a so-called script language, but the form of the program is not limited to this.

  FIG. 4 is a block diagram showing a configuration example of the controller 30 according to the present embodiment. As shown in FIG. 4, the controller 30 includes an auto dialer control unit 72, a TCP / IP communication control unit 74, a data conversion unit 76, a POE control unit 78, and an input / output control unit 80. Yes.

  The auto dialer control unit 72 dials the telephone number of the mobile terminal device 10 stored in the memory (not shown in FIG. 4) of the controller 30 and controls the communication of the audio signal via the mobile phone network 14. The TCP / IP communication control unit 74 controls communication of image data and control information via the Internet network 12.

  The data converter 76 converts the data so as to comply with TCP / IP, or converts the data according to the format of the device so that the data can be given to a device that does not comply with TCP / IP. POE is an abbreviation for Power over Ethernet (registered trademark). The POE control unit 78 controls the supply of data and power to the LAN cable connecting the interphone master unit 36 and the interphone slave unit 38. As a result, the interphone master unit 36 and the interphone slave unit 38 can operate without using a separate power line.

  Voice communication and data communication using the controller 30 configured as described above will be described.

  Usually, the interphone master unit 36 and the interphone slave unit 38 communicate with each other via the controller 30. For example, when a visitor from the outside operates a button of the intercom handset 38 or when the intercom handset 38 detects a visitor from an image taken by the camera 39 of the intercom handset 38, the button operation is performed. And data indicating visitor detection are transmitted from the intercom slave unit 38 to the interphone master unit 36 via the controller 30.

  In addition, the audio signal input to the microphone / speaker 41 of the interphone slave unit 38 is also transmitted to the interphone master unit 36 via the controller 30, and voice is emitted from the speaker (not shown) of the interphone master unit 36. Similarly, voice input to a microphone (not shown) of the interphone master unit 36 is also transmitted to the interphone slave unit 38 via the controller 30, and voice is emitted from the microphone / speaker 40 of the interphone slave unit 38.

  Further, a command is given from the intercom base unit 36 to the controller 20 by a button operation of the intercom base unit 36. The controller 30 can execute zoom-in, zoom-out, panning, on / off of various sensors, locking / release of the front door, and the like of the camera 39 connected to the interphone slave unit 38 according to the command.

  Communication of data and audio signals between the interphone master unit 36 and the interphone slave unit 38 via the controller 30 is in accordance with TCP / IP as described above.

  When the user is away from home, for example, the user operates a key of the interphone base unit 36 to operate in a normal operation mode (a mode in which communication is performed between the interphone base unit 36 and the interphone base unit 38). ) To the outing mode, the mode switching information is transmitted to the controller 30, and the controller 30 operates under the outing mode.

  Hereinafter, communication via the controller 30 according to the first embodiment will be described with reference to the flowcharts of FIGS. As shown in FIG. 5, when a visitor from the outside operates a button of the intercom handset 38 or the interphone handset 38 detects a visitor from an image captured by the camera 39 of the intercom handset 38. In step 501, a signal indicating a button operation and information indicating a detection result are transmitted from the intercom slave unit 38 to the controller 30 (step 502).

  The auto dialer control unit 72 of the controller 30 refers to the telephone number of the user stored in advance in the memory (not shown) of the controller 30 and dials the mobile terminal device 10 using the mobile phone network 14 ( Steps 503 and 504). As a result, the mobile terminal device 10 is called, and a communication line through the mobile phone network 14 is opened between the controller 30 and the mobile terminal device 10 when the user performs an operation to start a call (step 505). ).

  The voice of the visitor received by the microphone / speaker 41 of the intercom handset 38 is transmitted from the intercom handset 38 to the controller 30 according to TCP / IP. In the controller 30, the data conversion unit 76 converts an audio signal according to TCP / IP into an audio signal that can be transmitted via the mobile phone network 14, and sends it to the mobile phone network 14 via the auto dialer control unit 72. Send it out. The voice signal transmitted through the cellular phone network 14 is received by the telephone communication circuit 56 of the portable terminal device 10, and the voice of the visitor is reproduced from the speaker 62 of the portable terminal device 10.

  The user's voice received by the microphone 64 of the mobile terminal device 10 is sent from the telephone communication circuit 56 to the mobile phone network 14. The audio signal transmitted through the cellular phone network 14 is received by the controller 30. The data conversion unit 76 of the controller 30 converts the received audio signal into an audio signal according to TCP / IP, and transmits the converted audio signal to the interphone slave unit 38. Thus, the user's voice is reproduced from the microphone / speaker 41 of the intercom slave unit 38.

  In this way, voice communication via the controller 30 is realized between the intercom slave unit 38 and the portable terminal device 10 (step 506). 5 to 7, communication using the mobile phone network 14 is indicated by a broken line.

  An image captured by the camera 39 of the intercom slave unit 38 is transmitted to the controller 30 (step 507), and further transmitted from the controller 30 to the server 22 via the Internet 12 (step 508).

  More specifically, image data of an image taken by the camera 39 is transmitted to the controller 30 according to TCP / IP. Since the image data is sent to the Internet network 12 according to TCP / IP, the data conversion by the data conversion unit 76 is not performed, and the TCP / IP communication control unit 74 transmits the image data to the server 22.

  When the server 22 accepts the image data, the server 22 adds predetermined information (for example, a file name or a time stamp indicating the photographing time) to the image data, and stores the image data in a predetermined area of the database (step 509). ). The predetermined area in the database can be specified by a URL. The URL is stored in the database of the server 22 in association with the controller 30 that is the data transmission source. Thus, the image data transmitted from the controller 30 can be stored in a database area specified by a predetermined URL.

  The transmission of the image data taken by the camera 59 of the intercom slave unit 38 to the controller 30, the transmission of the image data from the controller 30 to the server 22, and the storage of the image data in the server 22 in the database (steps 507 to 507). 509) is preferably repeated as long as the communication of the audio signal between the controller 30 and the mobile terminal device 10 via the mobile phone network 14 is continued.

  As shown in FIG. 6, the communication (audio signal communication) via the controller 30 and the mobile phone network 14 is continued between the intercom handset 38 and the mobile terminal device 10 (step 600), and the user Can access the server 22 via the Internet 12 by operating the input device 52 of the mobile terminal device 10.

  As described above, the mobile terminal device 10 according to the present embodiment accesses a predetermined URL, logs in to the server 22, and stores it in a predetermined area in the database of the server 22 in which image data from the controller 30 is stored. A program (script) requesting transmission of the stored image data is stored in the memory 65.

  For example, when the user operates the input device 52 of the mobile terminal device 10 to cause the mobile terminal device 10 to read a script stored in the memory 65 and execute the script, the Internet communication circuit 58 of the mobile terminal device 10 is executed. Accesses a predetermined URL of the server 22 via the Internet network 12. The Internet communication circuit 58 of the mobile terminal device 10 reads the user ID and password stored in the memory by the script, and the Internet communication circuit 58 transmits the user ID and password to the controller 30 (step 601). Thereby, the portable terminal device 10 can log in to the server 22 (step 602).

  The image data of the image taken by the camera 39 of the intercom slave unit 38 is periodically transmitted to the server 22 via the controller 30 and stored in a predetermined area of the database of the server 22 (steps 603 to 605). ). Steps 603 to 605 are the same as steps 507 to 509 in FIG.

  Note that the script of the mobile terminal device 10 is automatically read when the user performs a call start operation of the mobile terminal device 10 (step 505), and indicates the URL stored in the memory of the mobile terminal device 10. Based on the information, the Internet communication circuit 58 of the mobile terminal device 10 may access the URL.

  According to the script of the mobile terminal device 10, the Internet communication circuit 58 of the mobile terminal device 10 transmits image data to the server 22 periodically after login or in response to the user's operation of the mobile terminal device 10. A request is transmitted (step 606). The server 22 refers to the time stamp added to each of the image data stored in the predetermined area of the database, searches for the latest image data, and transmits the searched image data to the mobile terminal device 10. (Steps 607 and 608).

  The internet communication circuit 58 of the mobile terminal device 10 receives the image data. An image corresponding to the received image data is displayed on the screen of the display device 54 (step 609).

  The transmission request of the image data to the server 22 by the Internet communication circuit 58 (step 606) and the voice signal communication between the mobile terminal device 10 and the controller 30 via the mobile phone network 14 are repeated. Is desirable.

  As described above, according to the present embodiment, the mobile terminal device 10 can receive image data via the Internet network 12 in a state where communication using the mobile phone network 14 is continued. In addition, image data captured by the camera 39 of the interphone slave unit 38 is periodically transmitted to the server 22, and the mobile terminal device 10 periodically requests transmission of the image data of the server 22 and receives the image data. Thus, the latest image captured by the camera 39 can be confirmed on the mobile terminal device 10.
