And provided (distributed) to terminal devices (personal computer PC and display control device CV) in the house through the home network. For example, the portal site created by the integrated management device TM is usually displayed on the liquid crystal display 52a of the display control device CV. In this portal site, a link to web content (web page group of each subsystem SSn) provided by each controller Cn is displayed as an icon, and if the touch panel is operated on any of the icons, the icon A web content transmission request message is transmitted from the display control device CV to the link destination URL (the IP address of the web page group held by each controller Cn) displayed in. Then, if the controller Cn that has received the transmission request message transmits a web page designated from among a group of web pages held by itself to the display control device CV, the web page of the controller Cn instead of the portal site. Is displayed on the liquid crystal display 52a.

  Next, the operation in the case of controlling and monitoring the equipment device Xm using the display control device CV will be described with reference to the sequence diagram of FIG.

  First, when the operation button 53a 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 integrated management device TM creates in advance a portal site that displays icons indicating links to the web pages of the subsystems SS1 to SS3, characters indicating the names of the individual subsystems SS1 to SS3, and stores them in a memory. When the message is received, the portal site data is read from the memory and transmitted 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 web page data (file) received from the integrated management device TM with a web browser executed by the microcomputer unit 50 (3). Then, if the touch panel is operated on the icon of the subsystem SS1 (4), the web address is linked to the link destination URL (IP address of the web page group held by the equipment controller C1) displayed by the icon. A web page transmission request message is transmitted by the browser (5). Then, when the equipment controller C1 that has received the transmission request message transmits the data of the web page held by itself to the display control device CV (6), the data (file) is opened by the web browser executed by the microcomputer unit 50. As a result, the web page of the subsystem SS1 is displayed on the liquid crystal display of the display unit 52 (7). In this web page, characters indicating the names and installation locations of the equipment devices X1 to X4 included in the subsystem SS1 (for example, “living air conditioner”, “living lighting”, etc.), and the operation of each equipment device X1 to X4 Characters indicating the state, buttons corresponding to operations for inverting the operation states of the respective equipment devices X1 to X4, and the like are displayed, and other web pages are linked to these buttons. Therefore, it is possible to monitor (confirm) the operation state of each equipment device X1 to X4 from the information displayed on the web page (8).

  Here, in the case of performing control for reversing the operating state of any of the equipment devices Xm, for example, control for turning off the lighting equipment (equipment device X2) that is currently lit, the operation state of the equipment device X4 is reversed on the web page. The touch panel is operated on the button corresponding to the operation to be performed (9). Then, a message indicating that the button 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 sent to the network address of the facility device controller C1 through the home network. It is transmitted (10). Then, the equipment controller C1 that has received this request message turns off the luminaire (facility equipment X2) (11). After that, the equipment controller C1 transmits web page data corresponding to the turn-off of the lighting fixture (facility equipment X2) to the display controller CV (12), and the web browser is executed by the microcomputer unit 50 of the display controller CV. By opening the data (file), another web page of the subsystem SS1 is displayed on the liquid crystal display 52a of the display unit 52 (13). In the said web page, the operation state of the lighting fixture (equipment apparatus X2) is changed from lighting to light extinction. However, if the control of the equipment device Xm fails for some reason, the equipment device controller control unit 10 creates a response message indicating that the control has failed and transmits it to the display control device CV, and the display unit 52 of the display control device CV. An error message (characters indicating that the requested control of the equipment Xm has failed) is displayed on the (liquid crystal display 52a).

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

  When an abnormality is detected in any of the security devices Y1 and Y2, and the security controller C2 acquires detection information of the occurrence of the abnormality from the security receiver SR (1), the security controller C2 sends a response message (hereinafter referred to as cooperation) (Referred to as a message) and broadcast (broadcast) in the home network (2), and also send a message to the center device SV to report the occurrence of an abnormality (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 52a 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, other controllers that have received the cooperation message, that is, the equipment device controller C1 and the image transfer controller C3, determine the content of the abnormality that has occurred from the detection information included in the received cooperation message, and determine a predetermined rule. Accordingly, if necessary, a control operation corresponding to the content of the abnormality is executed (6). For example, when a fire is occurring, the facility equipment controller C1 can turn on the luminaire to facilitate evacuation. However, if a gas leak has occurred, there is a risk that the spark generated when the power source is turned on or off will ignite the leaked gas when the operating state of the equipment device Xm is switched. Even if a control request message is received, control for all the equipment devices Xm is invalidated.

  By the way, when controlling and monitoring the equipment device Xm, the security device Yn, etc. using the display control device CV, a web page including buttons and icons corresponding to the target equipment device Xm, the security device Yn, etc. is displayed on the display unit 52. It may be necessary to follow a number of links before displaying on the liquid crystal display.

  Therefore, in the present embodiment, in the display control device CV, a request message for requesting a search for a web page that matches the search condition received by the operation unit 53 is created by the microcomputer unit 50 and transmitted to the controller Cn, and the search request is sent. The microcomputer 50 receives the search result performed by each controller Cn for the request message and displays it on the liquid crystal display of the display unit 52.

  The web page held by each controller Cn includes a keyword indicating at least one of the type, usage, and installation location of the housing facility. The keyword is used as a search condition with reference to the flowchart of FIG. A procedure for searching a web page will be described.

  When the switching input to the search mode is received by the operation unit 53 (step 1), the search condition input built-in web page stored in the memory unit 54 is read by the web browser executed by the microcomputer unit 50, and the display unit 52 Display on the liquid crystal display (step 2). In this search condition input built-in web page, buttons B1 to B16 for receiving input of characters such as hiragana, katakana, and alphanumeric characters using the touch panel of the operation unit 53 and an input character display area W for displaying the input characters are provided. Displayed (see FIG. 7A). For example, when the user operates the touch panel on the button Bk (k = 1 to 16) to input the character “Taro” and further operates the touch panel on the “Kanji” button B14, the microcomputer unit 50 is installed. The Japanese input system converts Hiragana “Taro” into Kanji “Taro”. When a search condition (for example, including the keyword “Taro”) is received by the operation unit 53 (step 3), the microcomputer unit 50 requests a search for a web page that matches the search condition. And are transmitted from the LAN interface unit 51 to each controller Cn (step 4).

  On the other hand, each controller Cn that has received the search request message searches the web page group held by itself for a web page that matches the search condition (that is, the web page including the keyword in the hypertext document), and performs a search. If a web page that matches the conditions is found, a response message including the URL of the web page is created. If no web page that matches the search conditions is found, a response message that the corresponding web page does not exist is created. It returns to the display control device CV through the network.

  In the display control device CV, when the LAN interface unit 51 receives a response message from each controller Cn (step 5), the microcomputer unit 50 finds a web page that matches the search condition in at least one of the controllers Cn based on the response message. It is determined whether or not it has been found (step 6). If no web page matching the search condition is found in any controller Cn, the microcomputer unit 50 displays a message such as “No web page matching the search condition was found”. 52 is displayed on the liquid crystal display 52 (step 7). On the other hand, when a web page that matches the search condition is found in any controller Cn, the microcomputer unit 50 transmits a transmission request message to the URL included in the response message returned from the controller Cn. A web page that matches the search condition is received from the controller Cn (step 8), a web page for displaying the search result is created and displayed on the liquid crystal display of the display unit 52 (step 9). After that, the microcomputer unit 50 ends the search mode if the input for ending the search mode is accepted by the operation unit 53, and returns to step 2 if the input for ending the search mode is not accepted by the operation unit 53, and is used for input of search conditions. The web page is displayed on the liquid crystal display of the display unit 52.

  Here, an example of the search result display web page is shown in FIG. The microcomputer unit 50 includes a functional block including a keyword (a character string “Taro”) from a hypertext document of a web page (a web page that matches a search condition) received from each controller Cn, for example, a character string “Taro”. The description part for displaying the button is copied and pasted into a new hypertext document to create a search result display web page. In this web page, as shown in FIG. 7B, three buttons B20, B21, B22 including the character string “Taro” and the previous screen (screen of the built-in web page for inputting search conditions) are returned. Button B23 is displayed. Then, if the user operates the touch panel on any button, for example, the button B20 displayed as “Taro's room lighting”, the display control device CV controls the equipment device controller C1 according to the procedure described above. , A control request message for turning on or off the equipment (lighting fixture) Xm corresponding to “Taro's room lighting fixture” is transmitted, and as a result, “Taro's room lighting fixture” can be turned on or off. . However, the character string “Taro” is an example of a keyword indicating the installation location of the housing equipment, and the keyword indicating the type of housing equipment (for example, lighting equipment or air conditioner) and the use (security, etc.) may be used. Is possible.

  In addition, a plurality of types of search keys prepared in advance instead of characters may be displayed on a built-in web page for entering search conditions. For example, icons indicating the type, usage, installation location, etc. of housing equipment (lighting fixtures) Icons, air conditioner icons, security device icons, etc.) may be displayed as search keys. When the touch panel is operated on any icon, for example, the icon of the lighting fixture, the search condition that the keyword “lighting fixture” is included, and the search that relates to the control or monitoring of the equipment device Xm that is the lighting fixture. Search is performed by condition.

  As described above, in the present embodiment, the LAN interface unit 51 generates a request message for requesting a search for a web page that matches the search condition received by the operation unit 53 that is an operation input receiving unit by the microcomputer unit 50 that is a search request unit. The web browser which is transmitted to each controller Cn and which is executed by the microcomputer unit 50 in response to the search request request message is received from the LAN interface unit 51 by the liquid crystal display of the display unit 52 Therefore, there is an advantage that a desired web page can be easily found and displayed without following links of many layers as in the prior art. In addition, it is possible to search with keywords indicating the type, usage, installation location, etc. of housing equipment, or to search using letters or a plurality of types of search keys prepared in advance, making it easier to find a desired web page There is an advantage that it can be found. In order to accept the switching input to the search mode, long press any of the operation buttons 53a, 53b, 53c, 53d provided in the operation unit 53, or operating a dedicated operation button (not shown).
