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, the operation in the case of performing control (switching) and monitoring of the operation state (warning state or non-warning state) of the security receiver SR using a home terminal device (for example, the display control device CV) is shown in FIG. This will be described with reference to a sequence diagram.

  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 indicates an icon indicating a link to the home page of the subsystems SS1 to SS3 registered in the list of the storage unit 5 and the names of the individual subsystems SS1 to SS3. A portal site that displays characters and the like is created, and data of the portal site is transmitted to the display control device 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). Then, if the touch panel is operated on the icon of the subsystem (security system) SS2 (4), the web browser uses the web browser to link the URL (security controller C2 IP address) displayed with the icon. A content (homepage) transmission request message is transmitted (5). When the security controller control unit 30 of the security controller C2 that has received the transmission request message transmits the data of its own home page to the display control device CV (6), the data (file) is transmitted by the web browser executed by the microcomputer unit 50. Is opened, the home page of the security system SS2 is displayed on the liquid crystal display of the display unit 52 (7).

Therefore, it is possible to monitor (confirm) the operation state of the security receiver SR, the detection status of each security device Y1, Y2, and the like from the information displayed on the homepage (8).

  Here, in the case of performing control for reversing the operation state of the security receiver SR, for example, control for switching from the non-warning state to the vigilance state, the touch panel is operated on a button corresponding to an operation for reversing the operation state of the security receiver SR on the homepage. Is operated (9). Then, a message indicating that the button has been operated by the web browser, that is, a message for requesting switching control for switching the security receiver SR to the alert state (request message) is addressed to the network address of the security controller C2 through the home network. It is transmitted (10). The security controller control unit 30 of the security controller C2 that has received this request message transmits a command (switch command) from the communication unit 32 to the security receiver SR, so that the operating state of the security receiver SR is not wary. The state is switched to the alert state (11). After that, if the security controller control unit 30 updates the content of the homepage in accordance with the switching of the operation state of the security receiver SR, and transmits the updated homepage data to the display control device CV (12), the display control device The updated home page of the security system SS2 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 CV (13). In the homepage, the operating state of the security receiver SR is changed from the non-warning state to the warning state.

  Next, an operation in the case of performing control (switching) and monitoring of the operation state (warning state or non-warning state) of the security receiver SR from outside the house using a portable terminal device (for example, the mobile phone MP) is performed. This will be described with reference to the sequence diagram of FIG.

  First, a householder uses the mobile phone MP to transmit a security system monitoring request message (operation status monitoring request message of the security receiver SR) to the center device SV (1), and the monitoring request message is held in the center device SV. After being polled from the security controller C2 (2), the center device SV transmits (transfers) the monitoring request message received and held from the mobile phone MP to the security controller C2 (3). In the security controller C2 that has received this monitoring request message, the security controller control unit 30 creates a monitoring response message indicating the current operating state (for example, non-warning state) of the security receiver SR and returns it to the center device SV ( 4). The monitoring response message is transferred from the center device SV to the mobile phone MP (5), and the status of the security system (security receiver) is displayed by displaying the monitoring response message transferred from the sensor device SV on the liquid crystal screen of the mobile phone MP. SR operating state) can be confirmed.

  In addition, the householder transmits a control request message (for example, a switching control request message for switching the operating state of the security receiver SR to the alert state) to the center device SV using the mobile phone MP (6). When polled from the security controller C2 after being held in the center device SV (7), the center device SV transmits (transfers) the control request message received and held from the mobile phone MP to the security controller C2. (8). In the security controller C2 that has received this control request message, the security controller control unit 30 transmits a command (switch command) to the security receiver SR from the communication unit 32, so that the operation state of the security receiver SR is in a non-warning state. (9). Thereafter, the security controller control unit 30 creates a control response message indicating that the operation state of the security receiver SR has been switched, and returns it to the center device SV (10). The control response message is transferred from the center device SV to the mobile phone MP (11), and the control response message transferred from the sensor device SV is displayed on the liquid crystal screen of the mobile phone MP, so that the operating state of the security receiver SR is changed. It can be confirmed that it has been switched. 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. Moreover, it is desirable that the switching of the operation state of the security receiver SR by the portable terminal device (for example, the mobile phone MP) is limited to the switching from the non-warning state to the warning state.

  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 a fire or gas leak 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 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.

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.

  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, 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 general, when going out, the power of the air conditioner or the lighting fixture is turned off and the security receiver SR is switched to a warning state, or when going to bed, the lighting fixture is turned off and the security receiver SR is switched to a warning state. In a specific situation, a plurality of predetermined controls are often performed at the same time. In such a case, an operation for each control is input by the operation unit 53 (touch panel) of the display control device CV. It is a very troublesome task.

  Therefore, in the present embodiment, symbols corresponding to three types of situations such as going out, staying at home, and sleeping are displayed on the screen of the portal site provided by the integrated management apparatus TM (for example, “going out”, “at home”, “sleeping”). Button), and when one of the buttons is selected in the operation unit 53 of the display control device CV, one or more control request messages associated in advance with each situation, For example, if the “going out” button is operated, a control request message for instructing the equipment controller C1 to turn off the air conditioner and all the lighting fixtures (power off and extinguish), and the security controller C2. A control request message for instructing the display control device CV to switch the security receiver SR to the alert state. Created by the emission unit 50, respectively transmitted via the LAN interface unit 51 the two kinds of control request message created for equipment controller C1 and the security controller C2. When the operation unit 53 accepts the operation of the “going out” button, the microcomputer unit 50 displays characters such as “accepting outing mode” on the liquid crystal display of the display unit 52.

  On the other hand, the equipment controller C1 performs control to turn off the air conditioner and all the lighting fixtures according to the control request message received from the display control device CV, and the security controller C2 controls the control request received from the display control device CV. In response to the message, control is performed to switch the operating state of the security receiver SR to a warning state. That is, when the user goes out, the user can turn off the air conditioner and all the lighting fixtures and switch the security receiver SR to the alert state only by operating the “outing” button in the operation unit 53 of the display control device CV. As compared with the case where an operation for each control is input by the operation unit 53 of the display control device CV, there are advantages that work efficiency is high and operability is improved.

  Further, in the microcomputer unit 50 of the display control device CV, a request message transmitted to the controller Cn and a response message transmitted from the controller Cn are recorded on a recording medium, and an operation input for confirming a history is received from the operation unit 53. Sometimes, a history of request messages and response messages, such as what kind of control was performed when and what detection information was received, can be displayed on the liquid crystal display of the display unit 52 as character information.
