  Explaining the basic operation of the intercom system 1, the dwelling unit intercom 11 and the system control device 14 constitute a network connected to each other by an interphone line 15 and perform communication by TCP / IP. The communication between the dwelling unit intercom 11 and the system control device 14 may be a unique protocol, but even in that case, communication by TCP / IP can be performed by protocol conversion.

  Further, the system control device 14, the lobby interphone 12, and the alarm monitoring panel 13 may be configured to perform communication by TCP / IP.

  The basic functions and operations of the intercom system 1 are the same as in the past. That is, when a calling operation is performed with the dwelling unit number designated by the lobby intercom 12, the system control device 14 designates the address of the dwelling unit called and calls the dwelling unit intercom 11 of the dwelling unit. When the call key 11e is operated on the called dwelling unit intercom 11, the system control device 14 configures an exclusive audio channel between the lobby intercom 12 and the dwelling unit intercom 11, so that the visitor and the dweller Allow phone calls. Thereafter, when the call key 11e is operated again or when a predetermined time has elapsed, the audio channel is released. Note that there may be a plurality of lobby interphones 12, and even in this case, the audio channel is exclusively controlled.

  Further, if the intercom system 1 is a television system, a video camera (not shown) provided on the lobby intercom 12 side and a call destination are provided between the time when the call operation is performed on the lobby intercom 12 and the time when the call channel is released. An exclusive video channel is configured with the dwelling intercom 11. If it does in this way, it can respond, monitoring the visitor's picture with dwelling intercom 11.

  Further, the basic functions and operations as an alarm monitoring system are the same as those in the prior art. That is, when the security sensor 16 detects the occurrence of an abnormality, the dwelling unit intercom 11 displays an alarm screen on the touch panel 11c and outputs an alarm message from the speaker 11f. Further, the dwelling unit intercom 11 notifies the alarm monitoring panel 13 of the occurrence of the abnormality. Upon receiving the notification, the alarm monitoring panel 13 outputs an alarm, and outputs an evacuation message or the like from the dwelling unit interphone 11 that has notified the occurrence of an abnormality or the neighboring dwelling unit intercom 11 according to the operation of the manager. In addition, the occurrence of abnormalities can be transferred to disaster prevention centers.

  Next, a characteristic operation of the present invention, that is, a basic operation related to the display of the energy information screen will be described. In short, when the dwelling intercom 11 receives a predetermined operation, it operates the web browser unit 11h to download and display the energy information screen provided by the content server 20 using the system control device 14 as a gateway. It is.

  In order to display the energy information screen, for example, the menu key 11d of the dwelling unit intercom 11 may be operated. The web browser unit 11h stores the address (or URL) of the content server 20 in advance, and connection to the content server 20 is started when the menu key 11d is operated. The connection request signal is output to the intercom line 15 and reaches the system control device 14.

  The gateway unit 14 c of the system control device 14 determines the transmission destination address of the connection request signal and sends the connection request signal to the Internet 21. The connection request signal sent to the Internet 21 reaches the content server 20 via a plurality of routers by a known routing technique. The content server 20 outputs a response signal to the connection request signal, but the response signal is transmitted to the dwelling unit intercom 11 along the path opposite to the previous connection request signal, and the connection between the dwelling unit intercom 11 and the content server 20 is performed. Established. Thereafter, the content server 20 downloads an energy information screen composed of HTML, XML, or the like in accordance with a request from the web browser unit 11h of the dwelling unit intercom 11, and displays it on the display unit of the web browser unit 11h, that is, the touch panel 11c.

  The measuring device 3 regularly notifies the content server 20 of the power usage of the dwelling unit via the residence building LAN 18, and the content server 20 stores the power usage of the dwelling unit transmitted from the measuring device 3 in the database. Record in section 20b. The notification of the power consumption may be performed spontaneously, for example, every predetermined time. However, it goes without saying that the content server 20 may connect to the measuring device 3 every predetermined time to request notification of power usage. The content server 20 analyzes the history of the power consumption of the dwelling unit notified from the measurement device 3, and generates the content of the energy information screen.

  Thus, in this invention, the energy information screen for each dwelling unit is produced | generated by the common content server 20, and the dwelling unit intercom 11 of each dwelling unit is the structure which downloads and displays the screen. Therefore, the circuit and the program for generating the screen need only be in the content server 20 and are unnecessary for the dwelling unit intercom 11, so that the cost is lower than the conventional configuration.

  FIG. 4A shows an example of the energy information screen. Here, the monthly power consumption change is displayed in a graph. Below that, advice on ecology and power usage is displayed, and further below that, a plurality of links such as links for switching the display on the power monitor screen of FIG. 4B are displayed. There is no particular restriction on the content of energy information. For example, a weekly power usage change, a monthly power usage change, a yearly power usage change, and the like may be simultaneously displayed or switched.

  FIG. 4B is also an example of the energy information screen, which is a power monitor screen for confirming the current power consumption. Along with the time, the current power consumption of the dwelling unit is displayed in a graph on the screen, resembling an analog meter, and the value is also displayed numerically. The graph display and the numerical display may be updated and displayed every minute, for example. In addition, a warning message such as “Exceeding the reference level” may be appropriately displayed on this screen based on the power consumption. The reference level may be set in advance in the measuring device 3, but the management screen may be called from the energy information screen and may be freely input there. The reference level value input at this time is transmitted from the content server 20 to the measuring device 3 through the residence building LAN 18 and stored therein.

  In order to display the power monitor screen as described above, it is necessary to sequentially notify the power usage amount from the measurement device 3 to the content server 20 at short time intervals. However, when trying to notify the amount of power used sequentially, the communication band of the residential building LAN 18 may be insufficient, depending on the number of units. Therefore, the content server 20 may notify the measurement device 3 of the start and end of the display of the power monitor screen, and the measurement device 3 may sequentially notify the power usage amount only during the display of the power monitor screen based on the notification. If it does in this way, it can prevent that the communication band of residence ridge LAN18 runs short.

  Further, the measuring device 3 compares the current power usage amount with a reference level of power usage that is set in advance or input and set by the content server 20, and if the level is equal to or higher than the reference level, Output to the connection terminal 3a. The dwelling unit intercom 11 monitors the notification signal at the second connection terminal 11b, and displays a warning in real time based on the monitoring result. As the display form, for example, the lighting color of the letter “energy” of the menu key 11d may be changed to red when it is above the reference level and green when it is below the reference level. Further, an icon indicating whether or not the current power usage amount is equal to or higher than a reference level may be displayed at a corner of the touch panel 11c. That is, the measuring device 3 outputs a notification signal to the signal line 19 when the measured power consumption exceeds a predetermined reference value, while the dwelling intercom 11 is based on the notification signal output to the signal line 19. Display the power usage status in real time. In such a configuration, even when the communication state of the Internet 21 is bad, the display is not delayed, so that a sense of incongruity is not given to the residents due to the display timing. Such power usage state display may be performed when the top menu is displayed on the touch panel 11c of the dwelling unit intercom 11.

  FIG. 5A and FIG. 5B are examples of such icons. When the current power consumption exceeds the reference level, an up arrow icon is displayed, and when it is less than the reference level, a down arrow icon is displayed on the touch panel 11c. Is displayed.

  FIG. 6 is a flowchart showing the basic signal transmission according to the system of the present invention in time series.

  In this flow, the menu key 11d is operated with the dwelling unit intercom 11 at time T1, a connection request signal is transmitted from the dwelling unit intercom 11 to the content server 20, and a response signal in response thereto is returned from the content server 20. After the connection is established, a screen request signal is transmitted from the dwelling unit intercom 11 to the content server 20, and screen information corresponding thereto is returned from the content server 20 to the dwelling unit intercom 11. At time T2, an energy information screen constituted by the screen information is displayed on the dwelling unit intercom 11.

  Thereafter, at time T3, the measuring device 3 detects that the power used exceeds the reference level, and a notification signal is output. At time T4, the dwelling intercom 11 changes the power usage state based on the notification signal. it's shown.

  The time T5 is a time for notifying the content server 20 of the power used. A connection request signal is transmitted from the measuring device 3 to the content server 20, and a response signal in response thereto is returned from the content server 20. After the connection is established, the power usage amount is notified from the measuring device 3 to the content server 20. At time T6, the content server 20 stores the power usage amount in the database 14c.
