  The network camera NC is well known in the art, and image data obtained by compressing a captured image with a predetermined compression method (for example, MPEG4 for a moving image, JPEG for a still image, etc.) via a home network. It is possible to execute imaging and perform remote control such as panning and tilting according to control information transmitted to the security controller C2 which is a proxy server device or received from the security controller C2 via the home network. Each network camera NC can be identified by an IP address, but a name for identification is given separately from the IP address. Such a name can be set by a user using a terminal device from the center device SV via an external network or from the integrated management device TM via a home network. For example, in the portal site provided by the control unit 1 of the integrated management device TM, the name of each network camera NC can be set using CGI (Common Gateway Interface), and the user can control the display. The name set using a terminal device such as the device CV or personal computer PC is transferred from the integrated management device TM to each network camera NC via the home network, and the name is assigned.

  Next, a case where a new subsystem (for example, SS1) is added to the home network will be described with reference to the sequence diagram of FIG.

  After the wiring of the subsystem SS1 is completed, when the equipment device controller C1 is started (powered on), the equipment device controller control unit 10 of the equipment device controller C1 that is a UPnP device sends a home network to the integrated management device TM that is a UPnP control point. Participation in is notified (NOTIFY) (1). The control unit 1 of the integrated management apparatus TM that has received the notification searches for a UPnP device (2), and as a response from the facility device controller C1 that is the notification source, a device such as the type of the controller (facility device controller C1) and a MAC address Receive information (3). Further, using DHCP, an IP address is assigned to the equipment controller C1 newly joining the home network. The control unit 1 of the integrated management apparatus TM adds the device information received from the equipment controller C1 to the list stored in the storage unit 5 and additionally registers the IP address as a link destination of the portal site ( 4). In addition, the equipment controller controller 10 of the equipment controller C1 stores the assigned IP address in the memory 16 as its own address (5). Note that, when the other subsystems SS2 and SS3 and the network camera NC are added, the same procedure is used, and the description thereof is omitted.

  Next, an operation in the case where control and monitoring of the equipment device Xm are performed using a home terminal device (for example, the display control device CV) will be described with reference to the sequence diagram of FIG.

  First, when the push button switch of the operation unit 53 is pressed, the microcomputer unit 50 transmits a portal site transmission request message from the LAN interface unit 51 to the integrated management device TM (1). The control unit 1 of the integrated management apparatus TM that has received the message transmits the portal site data shown in FIG. 14A to the transmission control source display control apparatus CV (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). If the touch panel is operated on the icon I04 of the subsystem SS1 (4), the web browser performs web content for the link destination URL (IP address of the equipment controller C1) displayed by the icon I04. A transmission request message of (homepage HP1) is transmitted (5). Then, if the equipment controller controller 10 of the equipment controller C1 that has received the transmission request message transmits the data of its own homepage HP1 to the display controller CV (6), the data is transmitted by the web browser executed by the microcomputer unit 50. By opening (File), the home page HP1 of the subsystem SS1 is displayed on the liquid crystal display of the display unit 52 (7). Therefore, it is possible to monitor (confirm) the operation state of each equipment device X1, X2 from the information displayed on the homepage HP1 (8).

  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 I14 (or I15) corresponding to the operation to be performed (9). Then, a message indicating that the icon I14 has been operated by the web browser, that is, a message (request message) for requesting to turn off the lighting device (facility device X2) is addressed to the IP address of the facility device controller C1 through the home network. (10). Then, in the equipment controller controller 10 of the equipment controller C1 that has received this request message, the lighting equipment (facility equipment X2) is turned off by turning off the relay of the relay terminal section 15 via the lighting equipment interface section 14. (11). After that, if the equipment controller controller 10 updates the content of the homepage HP1 in response to the lighting equipment (equipment equipment X2) being turned off, and transmits the updated homepage HP1 data to the display control device CV (12), By opening the data (file) with a web browser executed by the microcomputer unit 50 of the display control device CV, the updated home page HP1 of the subsystem SS1 is displayed on the liquid crystal display of the display unit 52 (13). 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. Here, if the web server function of each controller Cn always opens a port to the external network (Internet), for example, there is a high possibility that a malicious intruder will cause an abnormality in the system. In the embodiment, the web server function of each controller Cn normally polls the center device SV while closing the port, and the request message received from the portable terminal device is held in the center device SV. Then, the home network is protected by transferring the request message from the center device SV at the time of polling by the controller Cn that is the destination of the request message.

  As described above, each controller Cn periodically polls the center device SV, and if the center device SV does not hold a request message from the mobile phone MP, the center device SV simply receives an acknowledgment (ACK). ) Is simply returned to the controller Cn. Here, the householder uses the mobile phone MP to send a request message (for example, a monitoring request message for the operating state of the lighting fixture) to the center device SV (1), and after the monitoring request message is held by the center device SV. When polled from the equipment controller C1 (2), the center apparatus SV transmits (transfers) the monitoring request message received and held from the mobile phone MP to the equipment controller C1 (3). In the equipment controller C1 that has received this monitoring request message, the equipment controller controller 10 creates a monitoring response message indicating the current operating state (for example, lighting) of the lighting fixture (facility equipment X2) and sends it to the center apparatus SV. Reply (4). The monitoring response message is transferred from the center device SV to the cellular phone MP (5), and the monitoring response message transferred from the sensor device SV is displayed on the liquid crystal screen of the cellular phone MP, so that the operating state (lighting) of the lighting fixture is displayed. Can be confirmed.

  Further, the householder transmits a request message (for example, a control request message for turning off the lighting fixture) to the center apparatus SV using the mobile phone MP (6), and the equipment is stored after the control request message is held in the center apparatus SV. When polled from the controller C1 (7), the center device SV transmits (transfers) the control request message received and held from the mobile phone MP to the equipment device controller C1 (8). In the equipment device controller C1 that has received this control request message, the equipment device controller control section 10 turns off the lighting equipment (facility equipment X2) by turning off the relay of the relay terminal section 15 via the lighting equipment interface section 14. 9). Thereafter, the equipment device controller control unit 10 creates a control response message indicating that the lighting equipment (facility equipment X2) has been turned off and sends it back to the center apparatus SV (10). The control response message is transferred from the center device SV to the mobile phone MP (11), and it is confirmed that the lighting fixture is turned off by displaying the control response message transferred from the sensor device SV on the liquid crystal screen of the mobile phone MP. it can. However, when it takes a considerable time (for example, several minutes) from sending the control request message to returning the control response message, a message indicating that the control request message has been received is sent from the center device SV to the mobile phone MP. It is desirable to send.

  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. A response message (hereinafter referred to as a linkage message) including the message is generated and transmitted to the IP addresses of predetermined counterparts (for example, the equipment device controller C1 and the display control device CV) (2) and the center device A message for reporting the occurrence of an abnormality is also sent to the SV (3).

  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 ( 4).

  In addition, the center device SV notifies the householder who is out of the house by sending the report message of the occurrence of abnormality received from the security controller C2 to the mail address of the mobile phone MP registered in advance (5). .

  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 according to the content of the abnormality is executed if necessary according to a predetermined rule (6). 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 enabled, 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) The compressed image data is transferred as a response message to the center apparatus SV through the home network and the external network (4). The center device SV records (accumulates) the image data received from the image transfer controller C3 on a recording medium such as a hard disk (5).

  Further, when the answering function of the interphone master unit IM is enabled by the display control device CV via the image transfer controller C3 (6), the answering device setting is notified from the display control device CV to the center device SV. A message is sent (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 transferred as a response message to the center device SV through the home network and the external network (12). .

  In the center device SV, when the image data is transferred from the image transfer controller C3, 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), and The image data is stored in a recording medium (14).

  When the householder who has received the message wishes to confirm the visitor, the mobile phone MP may transmit an image reproduction request message 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 housekeeper who is out can check the visitor by viewing the image reproduced by the mobile phone MP.

  Next, an operation when the security controller C2 is used as a proxy server device and an image captured by the network camera NC is displayed on a terminal device (for example, a mobile phone MP) will be described with reference to the sequence diagram of FIG.

  When a request message for an image monitor is transmitted from the mobile phone MP to the center device SV (1), the center device SV is polled by the security controller C2 of the security system SS2 (2). The transmission request message for the web page for the image monitor that is held is transmitted to the security controller C2 (3). In the security controller C2 that has received the request message, the security control unit 30 reads the web page for the image monitor stored in the memory unit 35 and transmits it from the LAN interface unit 31 to the center device SV (4). This image monitor web page displays, for example, a list of names assigned to all network cameras NC existing in the home network in a predetermined order. The mobile phone is connected via the center device SV. It is transferred to the MP (5) and displayed on the liquid crystal screen by the web browser of the mobile phone MP. Then, if the user operates the cellular phone MP and selects the icon of the name of the network camera NC that desires to monitor the image, the selection result is transmitted to the center device SV (6), and further the security is sent from the center device SV. An image monitor request message including the selection result (name of the selected network camera NC) is transmitted to the controller C2 (7). Upon receiving this image monitor request message, the security controller control unit 30 of the security controller C2 transmits an image data acquisition request message via the home network with the IP address of the network camera NC to which the name is assigned as the destination (8 ), The image data captured by the network camera NC that has received the request message is transmitted to the security controller C2 (9). The security controller C2 transfers the image data received from the network camera NC as a response message to the center device SV through the home network and the external network (10). Then, the center device SV transmits the transferred image data to the mobile phone MP (11), and as a result, the image taken by the network camera NC can be displayed and confirmed on the mobile phone MP.

  Next, the point which becomes the summary of this invention is demonstrated.

  As shown in FIG. 13 and FIG. 14, the icons and characters displayed on the screen of the portal site page and the home pages HP1 to HP3 of the subsystems SS1 to SS3 are component data, such as the storage unit 5 and each controller of the integrated management device TM. It is stored in advance in the memory units 16, 35, and 45 of Cn. As described in the prior art, even if icons and characters composed of the same component data are used, the size of the icons and characters when displayed according to the size (screen size) of the display device included in the terminal device Will be different. Therefore, it is desirable from the viewpoint of usability that the user can freely change the size (size) of the icons and characters.

  Therefore, in the present embodiment, the integrated management device TM and each controller Cn display the parts such as icons and characters that constitute the web content (portal site and homepages HP1 to HP3) on the screen of the display device included in the terminal device. A plurality of types of component data having different appearances such as the size of the time are stored in advance in the storage unit 5 and each of the memory units 16, 35, and 45, and the component indicated by the instruction message received from the terminal device via the home network Web content can be created by selecting data.

  For example, on the portal site of the integrated management apparatus TM, as shown in FIG. 14B, a web page displaying an icon I07 corresponding to an operation button named “detailed setting” is prepared. When I07) is operated on the terminal device, a message requesting transmission of a web page for performing detailed settings is transmitted to the integrated management device TM via the home network, and the details are received from the integrated management device TM according to the request message. A web page indicating a setting menu is transferred to the terminal device, and the web page is displayed on the screen of the display device of the terminal device (see FIG. 15A). In this menu screen, icons “I51” to “I53” corresponding to “icon size”, “character size”, and “background” corresponding to operation buttons for selecting an item that can be changed by the user, and an operation for ending the change work are displayed. An “change complete” icon I54 corresponding to the button is displayed. For example, when the icon I51 is operated, a message requesting transmission of a web page for changing the size of the icon is transmitted to the integrated management device TM via the home network, and the integrated management device TM responds to the request message. A web page for changing the icon size is transferred to the terminal device, and the web page is displayed on the screen of the display device of the terminal device (see FIG. 15B). On the web page, four types of icons I61 to I64, which are large, standard, medium, and small, are displayed. By default, the “standard” icon I62 is used. Here, if the user wants to change the size of the icon to “small” smaller than the standard, the icon I64 may be operated. Then, a message indicating that the icon I64 is selected is transmitted from the terminal device to the integrated management device TM via the home network, and a sample web page in which the selected icons I64 are arranged vertically and horizontally is transmitted from the integrated management device TM to the terminal device. The web page is displayed on the screen of the display device of the terminal device (see FIG. 15C). When the “decision” icon I71 provided on the web page is operated, an instruction message instructing to use the component data having the size (small size) of the icon I64 as described above is displayed on the terminal device. To the integrated management device TM. As a result, in the integrated management device TM, in accordance with the instruction message received from the terminal device, the control unit 1 reads out the component data of the small icon from the component data stored in the storage unit 5 and newly creates a portal site. Are created and stored in the storage unit 5. However, the data file of the portal site before the change (default) is stored in the storage unit 5 as it is.

  The character size (character size) and background (web page screen background) can also be changed by the same procedure as the procedure for changing the icon size described above, and each controller Cn provides it. The icon size, character size, background, etc. of web content (homepage HP1-HP3, etc.) can be changed in the same procedure using the web page for detailed settings linked from the homepage HP1-HP3 of each controller Cn. Therefore, detailed description is omitted.

  By the way, the terminal in which the change operation was performed for each individual terminal device rather than uniformly applying the change of the icon size and the like on the portal site and the home pages HP1 to HP3 to all the terminal devices connected to the home network. Data files of the portal site for the device and the homepages HP1 to HP3 are individually created and stored in the storage unit 5 and the memory units 16, 35, and 45 in association with the IP address of the terminal device. In response to a web content transmission request, it is desirable to read and transfer the web content data file for the requesting terminal device from the storage unit 5 or the memory units 16, 35, and 45. In this way, when the screen size of the display device included in each terminal device is different or when the user is different for each terminal device, the web content is optimal for each terminal device or each user. Can be displayed.

  Here, referring to the contents (icon, character size, etc.) changed by any terminal device (for example, personal computer PC), the web content is changed by another terminal device (for example, display control device CV). If possible, it will be easier to make changes. Therefore, in the control unit 1 of the integrated management device TM, for example, in a situation where the web content for the personal computer changed by the personal computer PC is stored in the storage unit 5 in addition to the default web content, the terminal device other than the personal computer PC When a PC web content transmission request message is received from the display control device CV (for example, the display control device CV), the personal computer web content is read from the storage unit 5 and transmitted to the display control device CV. Then, the microcomputer unit 50 of the display control device CV displays the personal computer web content received from the integrated management device TM on the screen of the display device, and if the change operation is completed, the personal computer web content is displayed. An instruction message instructing to create web content for the display control device CV using the component data being used is transmitted to the integrated management device TM. In this way, the terminal device receives the web content for the other terminal device from the integrated management device TM, and at the same time, the web content for the other terminal device is not modified, or only necessary parts are corrected. Web content can be changed.

  Alternatively, the controller 10, 30, 40 of each controller Cn creates a new web content data file by changing the size of icons, characters, etc. according to an instruction from any terminal device (for example, personal computer PC). Information of parts data used for the web content (for example, icon size, character size, background type, etc.) is notified to all the controllers 10, 30, 40 of the controller Cn via the home network. Also good. For example, when the web content is changed from the personal computer PC to the equipment controller C1 and a new web content for the personal computer (homepage HP1 or the like) is created, the equipment controller controller 10 causes the web content for the personal computer to be created. Information on the component data used in the process is notified to the security controller C2 and the image transfer controller C3 via the home network. Then, when changing the icon size or the like to the web contents of the security controller C2 or the image transfer controller C3, a new web can be created simply by instructing to use the component data information notified from the equipment controller C1. Content (homepage HP2, HP3, etc.) can be easily created. Note that if part data information is broadcast and sent to the home network by broadcast, packets are also sent to unnecessary network terminals (such as network cameras NC and terminal devices), which increases the amount of communication more than necessary. There is a risk that. Therefore, it is desirable to send the packet data by unicast so that the component data information is transmitted only to the necessary network terminal, that is, each controller Cn.

  By the way, when newly adding component data such as icons and characters, additional component data stored in a portable storage medium such as a memory card is read into the integrated management device TM or each controller Cn to store the data. Alternatively, it may be stored in the memory units 16, 35, 45, or additional part data may be transferred from the center device SV via an external network, which makes it easy to add part data accompanying the addition of new functions. Can respond.
