The control unit 1 of the integrated management apparatus TM that has received the message transmits the portal site data shown in FIG. 8A to the display control apparatus CV that is the transmission request source (2).

  The display control device CV displays the portal site on the liquid crystal display by opening the data (file) received from the integrated management device TM with a web browser executed by the microcomputer unit 50 (3). When the touch panel is operated on the icon I11 of the homepage HP1 (4), a transmission request message of the homepage HP1 of the equipment device controller C1 is transmitted to the integrated management device TM by the web browser (5). And the control part 1 of the integrated management apparatus TM which received the transmission request message acquires the monitoring information (the current operation state of the equipment Xm) from the equipment controller C1 (6) and stores it in the storage unit 5. The data on the homepage HP1 is appropriately updated according to the monitoring information and then transmitted to the display control device CV (7). In the display control device CV, the data (file) is opened by a web browser executed by the microcomputer unit 50, whereby the home page HP1 of the equipment device controller C1 is displayed on the liquid crystal display of the display unit 52 (8). Therefore, it is possible to monitor (confirm) the operating state of each equipment device X1, X2 from the information displayed on the homepage HP1 (9).

  Here, when performing control for reversing the operating state of any of the equipment devices Xm, for example, performing control for turning off the lighting equipment (equipment device X2) that is currently lit, the operating state of the equipment device X2 is reversed on the homepage HP1. The touch panel is operated on the icon I21 (or I22) corresponding to the operation to be performed (10). Then, a message indicating that the icon I21 has been operated by the web browser, that is, a message (control request message) requesting to turn off the lighting fixture (facility device X2) is transmitted to the integrated management device TM through the home network. (11). And the control part 1 of the integrated management apparatus TM which received this control request message transfers the said control request message to the equipment device controller C1 (12). The equipment controller controller 10 of the equipment controller C1 turns off the relay of the relay terminal section 15 via the lighting equipment interface section 14 in response to the control request message received from the integrated management device TM. The device X2) is turned off (13). Thereafter, the fact that the equipment controller controller 10 has turned off the lighting equipment (equipment X2) is sent as monitoring information to the integrated management device TM (14). The control unit 1 of the integrated management device TM updates the content of the homepage HP1 based on the monitoring information received from the equipment device controller C1, and transmits the updated data of the homepage HP1 to the display control device CV (15). Then, the updated home page HP1 of the equipment controller C1 is displayed on the liquid crystal display of the display unit 52 by opening the data (file) with a web browser executed by the microcomputer unit 50 of the display control device CV (16). In the homepage HP1, the operating state of the lighting fixture (equipment device X2) is changed from lighting to extinguishing.

  Next, the operation in the case of controlling and monitoring the equipment device Xm from outside the house using a portable terminal device (for example, the mobile phone MP) will be described with reference to the sequence diagram of FIG.

  First, when the center device SV is accessed using the Internet connection function of the mobile phone MP, the center device SV transfers web content for selecting a service that can be provided after performing predetermined authentication to the mobile phone MP. Then, for example, when a service for checking the state of the lighting device (facility device X2) is selected from the web content displayed on the screen of the display device of the mobile phone MP, the mobile phone MP sends the lighting device to the center device SV. A monitoring request is transmitted (1). In the center device SV, a monitoring request message including a monitoring request received from the mobile phone MP is transmitted via an external network (Internet) to the integrated management device TM in which the correspondence relationship with the mobile phone MP is registered in advance ( 2). The control unit 1 of the integrated management apparatus TM that has received the monitoring request message acquires the monitoring information (the current operating state of the equipment Xm) from the equipment controller C1 (3), and sends a monitoring response message including the acquired monitoring information. Transmit to the sensor device SV (4). The monitoring response message is transferred from the center device SV to the mobile phone MP (5), and the monitoring response message transferred from the sensor device SV is displayed on the screen of the display device of the mobile phone MP so that the operating state of the lighting fixture ( Can be confirmed.

  When a service for turning off the lighting device is selected from the web content displayed on the screen of the display device of the mobile phone MP, a control request for the lighting device is transmitted from the mobile phone MP to the center device SV (6). ). The center device SV transmits a control request message including the control request received from the mobile phone MP to the integrated management device TM via the external network (Internet) (7). And the control part 1 of the integrated management apparatus TM which received this control request message transfers the said control request message to the equipment device controller C1 (8). The equipment controller controller 10 of the equipment controller C1 turns off the relay of the relay terminal section 15 via the lighting equipment interface section 14 in response to the control request message received from the integrated management device TM. The device X2) is turned off (9). Thereafter, the fact that the equipment controller controller 10 has turned off the lighting equipment (equipment X2) is transmitted as monitoring information to the integrated management device TM (10). The control unit 1 of the integrated management device TM transmits a control response message including the monitoring information received from the equipment device controller C1 to the center device SV via the external network (11). The control response message is transferred from the center device SV to the mobile phone MP (12), and the lighting device is turned off by displaying the control response message transferred from the sensor device SV on the screen of the display device of the mobile phone MP. I can confirm that.

  Next, in the security system (subsystem SS2), the operation when the security controller C2 obtains detection information indicating the occurrence of an abnormality (for example, the occurrence of a fire or gas leak or the entry of a suspicious person) from the security receiver SR. This will be described with reference to the sequence diagram of FIG.

  When an abnormality is detected in any one of the security devices Y1 and Y2, and the security controller control unit 30 of the security controller C2 acquires detection information on the occurrence of the abnormality from the security receiver SR (1), the security controller control unit 30 detects the detection information. Is transmitted to the integrated management device TM via the home network (2). The control unit 1 of the integrated management apparatus TM creates a response message (hereinafter referred to as a cooperation message) including the detection information received from the security controller C2, and determines a predetermined counterpart (for example, the equipment device controller C1, image). A message is sent to the IP address of the transfer controller C3 and the display control device CV) (3), and a message for notifying the occurrence of an abnormality is also sent to the center device SV (4).

  In the display control device CV that has received the cooperation message, the microcomputer unit 50 determines the content of the abnormality (for example, the occurrence of a fire or gas leak or the entry of a suspicious person) from the detection information included in the cooperation message received. , The alarm sound corresponding to the content (for example, a voice message such as “A fire has occurred. Please evacuate immediately.” Or “A suspicious person has entered.”) An alarm display corresponding to the content of the abnormality (for example, a message such as “A fire has occurred at XX” or “A suspicious person has entered XX”) is displayed on the liquid crystal display of the display unit 52 ( 5).

  In addition, the center device SV transmits the abnormality occurrence notification message received from the integrated management device TM to the e-mail address of the mobile phone MP registered in advance so that the occurrence of the abnormality is notified to the user (housekeeper who is out). Notify (6).

  On the other hand, in other controllers that have received the cooperation message, that is, the equipment device controller C1 and the image transfer controller C3, generated from the detection information included in the cooperation message received by the equipment device controller control unit 10 and the image transfer controller control unit 40. The content of the abnormality is judged, and a control operation corresponding to the content of the abnormality is executed if necessary according to a predetermined rule (7). For example, when a fire is occurring, the facility device controller control unit 10 can turn on the luminaire to facilitate evacuation. However, when a gas leak has occurred, if the operating state of the equipment Xm is switched, there is a risk that the spark generated when the power is turned on or off may ignite the leaked gas. Then, even if a control request message is received, the control for all the equipment devices Xm is invalidated. Alternatively, when a suspicious person enters, the image transfer controller control unit 40 acquires image data obtained by imaging the monitoring area from the sensor camera SC, and transfers it to the center apparatus SV via the integrated management apparatus TM together with the suspicious person's intrusion information. Thus, the user who is out can check the image of the monitoring area using the mobile phone MP.

  Next, the image captured by the intercom system (subsystem SS3) door phone slave unit DS is stored in the center device SV and the stored image is played back by the terminal device (for example, the mobile phone MP). This will be described with reference to the sequence diagram of FIG. However, in the following description, a case where only an image is stored will be described, but a call voice can be stored in the center device SV together with the image and can be reproduced by the terminal device.

  As described above, when the visitor presses the call button (1), the image transmission function of the doorphone slave unit DS is activated, and the image (image data) captured by the camera of the doorphone slave unit DS becomes the interphone parent. To the machine IM. The intercom master unit IM transmits the image data received from the door phone slave unit DS to the image transfer controller C3 (2). In the image transfer controller C3, the image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 using a predetermined compression method (for example, MPEG4 for moving images, JPEG for still images). (3) Then, the compressed image data is transferred as a response message to the integrated management apparatus TM via the home network (4). The integrated management device TM transfers the image data transferred from the image transfer controller C3 to the center device SV via the external network. The center device SV records (accumulates) the image data received from the image transfer controller C3 via the integrated management device TM on a recording medium such as a hard disk (5).

  When the answering function of the interphone master unit IM is set to be valid by the display control device CV via the integrated management device TM and the image transfer controller C3 (6), the display control device CV leaves the center device SV. A message notifying the recording setting is transmitted (7). Then, when the visitor presses the call button when the answering machine function is set to be effective (8), the image transmission function of the doorphone slave unit DS is enabled and the image is captured by the camera of the doorphone slave unit DS. The image (image data) is transmitted to the interphone master unit IM, and the interphone master unit IM transmits the image data received from the door phone slave unit DS to the image transfer controller C3 (9) and the image data to the memory unit 45. Store (record) (10). The image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 (11), and the compressed image data is sent as a response message from the integrated management device TM via the home network and the external network to the center device. Transfer to SV (12).

  In the center device SV, when image data is transferred from the image transfer controller C3 via the integrated management device TM, a message is sent to the e-mail address of the mobile phone MP registered in advance to notify the resident who is out. (13) Further, the image data is stored in the recording medium (14).

  When the user (household) who has received the message wants to confirm the visitor, an image reproduction request message may be transmitted from the mobile phone MP to the center device SV (15). The center device SV that has received the request message processes (converts) the image data stored in the recording medium into a file format that can be played back by the mobile phone MP (16), and transmits the processed image data to the mobile phone MP. (17). As a result, the user can confirm the visitor by viewing the image reproduced by the mobile phone MP.

  Next, the operation in the case where the image captured by the doorphone slave unit DS is reproduced on the terminal device (for example, the mobile phone MP or the display control device CV) using the image monitor function of the interphone master unit IM is shown in the sequence of FIG. This will be described with reference to the drawings.

  When an image monitor request message is transmitted from the mobile phone MP to the center device SV (1), the center device SV transmits the request message to the integrated management device TM via the external network (2). Further, the control unit 1 of the integrated management apparatus TM transfers the image monitor request message received from the center apparatus SV to the image transfer controller C3 via the home network (3). In the image transfer controller C3 that has received the image monitor request message, the image transfer controller control unit 40 transmits a control signal for enabling the image monitor function of the interphone master unit IM from the communication unit 42 (4). By receiving the control signal, the image monitor function of the intercom master unit IM is enabled (5). Then, the interphone master unit IM activates the image transmission function of the door phone slave unit DS by supplying power via the telephone line, receives the image captured by the camera of the door phone slave unit DS, and displays the image data as an image. The data is transmitted to the transfer controller C3 (6). In the image transfer controller C3, the image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 (7), and the compressed image data is transferred as a response message to the integrated management apparatus TM via the home network. Further, the response message is transferred from the integrated management device TM to the center device SV via the external network (8). Then, the image data transferred by the center device SV is transmitted to the mobile phone MP (9), and as a result, the image captured by the door phone slave unit DS can be reproduced and confirmed by the mobile phone MP.

  Further, the home page HP3 of the image transfer controller C3 is provided with an icon I41 for effectively setting the image monitor function of the intercom master unit IM (see FIG. 8D), and the operation unit of the display control device CV. When the operation of the icon is accepted in 53, the microcomputer unit 50 transmits an image monitor request message to the image transfer controller C3 via the integrated management device TM through the LAN interface unit 51 (10) (11). In the image transfer controller C3 that has received this image monitor request message, the image transfer controller control unit 40 transmits a control signal for enabling the image monitor function of the interphone master unit IM from the communication unit 42 (12). Receiving the control signal enables the image monitor function of the intercom master unit IM (13). Then, the interphone master unit IM activates the image transmission function of the door phone slave unit DS by supplying power via the telephone line, receives the image captured by the camera of the door phone slave unit DS, and displays the image data as an image. The data is transmitted to the transfer controller C3 (14). In the image transfer controller C3, the image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 (15), and the compressed image data is transferred as a response message to the integrated management apparatus TM (16). Further, the integrated management device TM transfers to the display control device CV (17). In the display control device CV, the received image data is decompressed by the microcomputer unit 50 and output to the display unit 52, whereby the image captured by the door phone slave unit DS is displayed on the liquid crystal display of the display unit 52.

  As described above, according to the present embodiment, residential equipment is controlled and monitored for each of the plurality of subsystems SS1 to SS3, and a home network using a general-purpose communication protocol is configured by the plurality of subsystems SS1 to SS3. Therefore, since the subsystems SS1 to SS3 can be linked through the home network, it is more flexible in changing market needs and improving the function of housing equipment than in the conventional case where all housing equipment is connected to a single master unit. And it can respond quickly.

  By the way, in the equipment device controller C1, the current time is measured by the timer section 18, but the equipment device Xm is controlled at a preset time (for example, by using the timer function mounted in the equipment device controller control section 10). The lighting fixtures can be turned on / off and the air conditioner can be turned on / off. The timer function can be set on a timer setting web page linked from the home page of the subsystem SS1. Specifically, using a terminal device such as a personal computer PC or a display control device CV, open the timer setting web page linked from the home page of the subsystem SS1 with a web browser, and select the equipment Xm to be controlled. If necessary items such as control contents (for example, power-on) and control execution time (set time) are input, the input items are recorded in the memory unit 16. And if the present time time-measured by the time measuring part 18 corresponds with design time, the equipment apparatus controller control part 10 will control the equipment apparatus Xm. Also, the necessary items are registered in the center device SV using a terminal device (such as a personal computer PC, a display control device CV, or a mobile phone MP), and a control request message corresponding to the set items is integratedly managed from the center device SV at the set time. It is also possible to transmit to the equipment device controller C1 from the device TM and further from the integrated management device TM and to control the equipment device Xm by the equipment device controller control unit 10. Further, the control units 10, 30, and 40 of the controllers C1 to C3 each independently transmit monitoring information to the integrated management device TM at predetermined times, and the monitoring information is stored in the storage unit 5 in the integrated management device TM. It may be stored and managed.

  The names of the equipment device Xm and the security devices Y1, Y2, etc. displayed on the web pages of the subsystems SS1 to SS3 can be changed by selecting from candidates prepared in advance using the display control device CV. is there. Alternatively, an arbitrary name can be given using the personal computer PC via the center device SV.

  By the way, among the terminal devices connected to the home network, for the display control device CV, the integrated management device TM can grasp the size, resolution, etc. of the display device in advance. Therefore, between the integrated management device TM and the display control device CV, screen data (for example, JPEG image data) for displaying the screens of the portal site and the home pages HP1 to HP3 instead of the web content is integrated management device TM. To the display control device CV to display the image on the liquid crystal screen of the display control device CV, and the display control device CV transmits the position information on the touch panel of the operation unit 53 to the integrated management device TM for integration. Based on the screen data and the position information in the control unit 1 of the management device TM, it is also possible to accept an operation input made in the display control device CV. In this way, the processing burden on the microcomputer unit 50 of the display control device CV can be reduced.

  In addition, in the control unit 1 of the integrated management device TM, it is desirable to store in the storage unit 5 a record when a request message or a response message is received from each controller Cn, terminal device, or center device SV. Such a record (log) consists of a file representing the IP address of the message sender, the message content, the reception time, etc. in text data, and is read from the storage unit 5 as needed in response to a browsing request from the terminal device. Transferred. However, saving logs for all types of messages consumes the storage capacity of the storage unit 5, so that logs may be saved only for predetermined messages.

  By the way, when a new housing facility is added in each of the subsystems SS1 to SS3 and when an existing housing facility is removed (leaved), the controllers 10, 30, and 40 of the controllers C1 to C3 are connected via the home network. You may make it transmit the addition / separation information (such as the kind of the housing equipment added or removed) of housing equipment to the integrated management apparatus TM. The housing facility addition / removal information is transmitted to the display control device CV by the control unit 1 of the integrated management device TM that has received the portal site transmission request from the display control device CV, and is displayed on the liquid crystal screen of the display control device CV for a certain period of time. It is desirable to display and inform the user.
