And a control unit 73 that performs overall control of the transmission / reception unit 71, the image display unit 72, and the like.

  Further, the electric device controller C1 in FIG. 1 has an interface function with the integrated device TM and an interface function with the electric device Xmn conforming to the Japan Electric Manufacturers Association (JEMA) unified standard. When the electric device controller C1 receives a control request message from the terminal device TU via the integrated device TM, the electric device controller C1 individually controls each electric device Xmn via the information transmission path Lj and operates (in the case of a lighting fixture). Is switched on and off (in the case of lighting fixtures) a function (control function), and when a monitoring request message is received from the terminal device TU via the integrated device TM, each electric power is transmitted via the information transmission path Lj. The terminal which is the source of the request message and obtains the operation status (operation [lit] or stop [extinction]) of the device Xmn individually, and the response to the control request and the monitoring request (operation status of each electrical device Xmn) It has a function (monitoring function) for transmitting to the device TU via the integrated device TM. In addition, the electric device controller C1 stores in advance device name information of the electric device Xmn under its control, name information of the room Rn, etc., and displays the name and operation state of the electric device Xmn with characters and symbols. It also has a function (web server function) for creating web content (web page) and providing (distributing) the web content to the terminal device TU in response to a request from the terminal device TU.

  Incidentally, FIG. 9 shows an example of a screen displayed on the display screen 72a when the terminal device TU is started up or in a state where the terminal device TU is switched to the top screen of the control panel. The title bar TB indicating the panel) is displayed, and on the lower side thereof, the operation / stop state of each electric device Xmn is switched to a preset state in accordance with each scene of “at home”, “outing”, and “good night” Scene selection buttons B1, B2, and B3 are displayed. Below the scene selection buttons B1, B2, and B3, a display unit W1 that displays information distributed from the center device SV (for example, weather forecasts in the surrounding area) with pictures and characters is arranged. The page includes a previous page button B4 and a next page button B5 for shifting to the previous page or the next page, and a menu button B6 for shifting to the menu screen.

  Then, when the user touches the menu button B6 on the initial screen of FIG. 9, the control unit 73 of the terminal device TU controls the transmission / reception unit 71 to transmit a display request for the menu screen to the integrated device TM. Upon receiving the menu screen display request transmitted from the terminal device TU, the integrated device TM returns a web page for displaying the menu screen to the terminal device TU that is the transmission source of the display request, and the terminal device TU The web page received by the transmission / reception unit 71 is displayed on the display screen 72 a of the image display unit 72. 10A and 10B show an example of a menu screen displayed on the display screen 72a of the image display unit 72 of the terminal device TU. Title bars TB1 and TB2 for displaying screen names (for example, “menu (1/2)” and “menu (2/2)”) are displayed on the upper side of the menu screen, and a desired menu is selected in the center of the screen. Menu selection buttons (selection buttons BT1 to BT4 on the screen of FIG. 10A, selection buttons BT5 and BT6 on the screen of FIG. 10B), and the previous page that transitions to the previous page or the next page at the bottom of the screen Button BT7 and next page button BT8 are respectively displayed. Each menu selection button BT1 to BT6 is displayed with characters (“remote control”, “wireless remote control”, “eco monitor”, etc.) indicating the contents of the corresponding menu, and the next page button BT8 is displayed on the screen of FIG. When the touch operation is performed, the display screen of the image display unit 72 is switched to the menu screen of FIG. 7B through the same processing as described above, and when the previous page button BT7 is further touched on the screen of FIG. The display screen of the image display unit 72 can be switched to the menu screen shown in FIG.

  By the way, in the power monitoring system of this embodiment, FIG. 10A displayed on the image display unit 72 in the terminal device TU such as the personal computer PC in the house, the display control device CV, or the portable terminal PT connected to the Internet. When the user touches the selection button BT3 for selecting the eco-monitor screen on the menu screen, the control unit 71 performs real power monitoring from the transmission / reception unit 71 to the energy management unit 2 via the integrated device TM in response to the touch operation. When the request message is transmitted and the control unit 2c of the energy management unit 2 receives the power real monitor request via the integrated device TM, the control unit 2c receives the main power amount and the branch breaker Bmn input from the calculation unit 2b. Based on branch power, main power and branch power for each branch breaker Bmn Power real monitor image data for displaying the current value of the current power is generated, and the generated power real monitor image data is transmitted to the terminal device TU that has transmitted the power real monitor request via the integrated device TM. .

  In the terminal device TU that has received the power real monitor image data, the control unit 73 controls the display of the image display unit 72 to display the power real monitor image data on the display screen of the image display unit 72. It is possible to monitor the current value of the power amount and the branch power amount for each branch breaker Bmn. FIG. 11A is an example of a power real monitor image displayed on the display screen 72a of the image display unit 72 of the terminal device TU. In the power real monitor screen (energy management top screen) of FIG. 11A, a title bar TB3 indicating the name of the screen (for example, “Eco-monitor (1/2)”) is displayed at the upper side of the screen, and at the center of the screen. The display unit SY1 that shows the electricity charges for the current month (data of yesterday and today) and the pictogram P1 that shows the electric equipment that consumed the most electricity yesterday are displayed. A next page button BT9 and a menu button BT10 for transition are respectively displayed.

  By the way, the electric device Xmn connected to the branch breaker Bmn is not only one that consumes zero power when stopped, such as a lighting fixture, but also one that generates standby power even when stopped, such as a television or an air conditioner. Some of them are always working without stopping, such as refrigerators. Therefore, even when the electric device Xmn is in a stopped state, a branch current may flow through the branch breaker Bmn to which the electric device Xmn is connected. Therefore, for each branch breaker Bmn, the power supply of the electric device connected to the branch breaker A branch current in a stop state with the switch turned off (hereinafter referred to as a stop-time branch current) is set in advance. In addition, when the branch breaker Bmn is connected to the outlet in the room Rn, various electric devices may be connected to the outlet. Therefore, the branch current when the branch circuit is stopped is the stop state of the electric device. The sum of the standby current consumed by the electric current and the operating current of an electric device such as a refrigerator that does not normally stop.

  Therefore, in the terminal device TU, by performing a setting operation on a setting screen (not shown), a branch current setting image at the time of stopping of the branch breaker Bmn to be set is displayed, and the power supply of the electrical equipment connected to the target branch breaker Bmn When the setting button displayed on the screen is touch-operated in a state where the switch is turned off (except for those that are always in an operating state such as a refrigerator), the control unit 73 of the terminal device TU starts from the transmission / reception unit 71. The energy management unit 2 is transmitted with a setting request signal for setting a branch current when the branch breaker Bmn to be set is stopped. At this time, when the control unit 2c of the energy management unit 2 receives the stop branch current setting request signal via the integrated device TM, the detection value of the branch current of the setting target branch breaker Bmn is obtained via the calculation unit 2b. Then, the branch current detection value is set in the storage unit 2e as the branch current when the branch breaker Bmn is stopped (electric consumption during stop). This process is performed for all branch breakers Bmn, and a stop-time branch current is set for each branch breaker Bmn.

  Also, once the stop branch current of each branch breaker Bmn is set by the controller 2c, the stop branch current is updated by executing the processing described below. In the control unit 2c, the branch current detection value of the setting target branch breaker Bmn registered in the storage unit 2e and the current stop branch current are sequentially compared, and the branch current detection value is determined from the stop branch current. If the branch current detection value is equal to or greater than the stop branch current, the branch current detection value at this time is set to the storage means 2e. The stop branch current can be set to an appropriate value at any time.

  Then, the control unit 2c acquires the branch current detection value for each branch breaker Bmn via the calculation unit 2b, and the branch current detection value of each branch breaker Bmn and the branch breaker Bmn read from the storage unit 2e. When the difference obtained by subtracting the stop branch current value from the branch current detection value is equal to or greater than a certain value, the one or more electrical devices Xmn connected to the branch breaker Bmn When it is determined that the operating state is present and the difference obtained by subtracting the steady branch current value from the branch current detection value is smaller than a certain value, it is determined that the electrical device Xmn connected to the branch breaker is in a stopped state.

  In this way, the control unit 2c detects the operating / stopped state of the electric device Xmn connected to each branch breaker Bmn, but the control unit 2c measures the current time (not shown). The non-operating period of the electric equipment Xmn connected to each branch breaker Bmn is obtained based on the time measurement result. When the electrical device Xmn is restarted after the preset continuous non-operation period, the restarting device detection means 2d of the control unit 2c restarts based on the operation / stopped state of each electrical device Xmn. The branch breaker Bmn to which the operated electric device Xmn is connected is detected. At this time, the image data generating means 2f reads from the storage means 2e a message for notifying the precautions when restarting the electrical equipment Xmn connected to the branch breaker Bmn detected by the restarting equipment detection means 2d. Image data for displaying the read message is generated, and the generated image data is transmitted to the terminal device TU via the integration device TM.

  In the terminal device TU, the screen of FIG. 9 is switched to the top screen of the control screen, the screen of FIG. 10 is switched to the menu screen, and the screen of FIG. When the image data for displaying the above message is transmitted from the energy management unit 2 via the integrated device TM in the state in which these screens are displayed, the above message is displayed. The child screens to be displayed are displayed in a superimposed manner (pop-up display), and the user can be informed of precautions when restarting the electric device Xmn that has been suspended for more than the continuous inoperative period. FIG. 11B is an example of a screen that displays a message for notifying the precautions when restarting the air conditioner on the image display unit 72 of the terminal device TU. The above message is displayed on the display screen 72 a of the image display unit 72. The child screen G1 to be displayed is superimposed (pop-up display). The sub-screen G1 displays a message (for example, “Did you clean the filter?”) M1 for notifying the precautions about the electric equipment to be restarted, and a confirmation button BT11 for performing a confirmation operation. . The message M1 may be set as appropriate according to the intended use or place of use of the electrical equipment Xmn to be reactivated. For example, when the electrical equipment Xmn that has been reactivated after a continuous non-operation period is a floor heater. May display a message such as “Did you remove ticks since it has been a long time?”, Or instead of displaying it in a pop-up, it may be displayed on the entire screen.

  Here, when the user confirms the content of the message M1 and performs a touch operation on the confirmation button BT11 as an operation unit, the control unit 73 of the terminal device TU displays a confirmation signal generated according to the operation of the confirmation button BT11. The data is transmitted from the transmission / reception unit 71 serving as a transmission unit to the energy management unit 2 via the integrated device TM. At this time, the control unit 2c of the energy management unit 2 receives the confirmation signal transmitted from the terminal device TU, generates power real monitor image data for displaying electricity usage, and generates the generated power real monitor image. Since the data is transmitted to the terminal device TU that is the transmission source of the confirmation signal via the integrated device TM, the display of the terminal device TU is switched to the power real monitor screen. In this case, until the user operates the confirmation button BT11 displayed on the display screen of the terminal device TU, the above-described sub-screen G1 is displayed as a pop-up, and thus the user may miss the display of the sub-screen G1. In addition, by touching the confirmation button BT11 of the terminal device TU, it is possible to switch to a power real monitor screen that displays the amount of electricity used.

  By the way, in this system, when one of the electric devices Xmn is restarted after exceeding the continuous non-use period, when the electric device Xmn is restarted from the control unit 2c of the energy management unit 2 through the above-described processing. The image data of the small screen G1 that displays the message for notifying the notice is transmitted to the terminal device TU via the integration device TM and displayed on the image display unit 72 of the terminal device TU. After that, when the control unit 2c receives a confirmation signal transmitted from the terminal device TU in response to an operation on the terminal device TU, the control unit 2c performs the above-described processing to display the electricity usage amount on the display screen of the terminal device TU. The screen is switched to the monitor screen. When a certain period of time elapses after the image data of the child screen G1 is transmitted to the terminal device TU, power real monitor image data is generated, and the image data is converted into the integration device TM. It is also possible to transmit to the terminal device TU that has transmitted the image data of the sub-screen G1 via. In this case, even if the user does not intentionally perform any operation, the message indicating the precautions about the reactivated electric device Xmn is displayed on the image display unit 72 of the terminal device TU for a certain period of time. It is possible to switch to a monitor screen that displays the usage amount, and to continuously monitor various types of electricity usage.

  Further, in this system, information on the electrical equipment Xmn connected to each branch breaker Bmn can be set in the control unit 2c of the energy management unit 2, so that electricity that is frequently used only in a specific period is concentrated. Information on the device Xmn (air conditioner, floor heating, etc.) and the branch breaker Bmn to which the electric device Xmn is connected is set in advance, and an operation start correspondence message to be displayed when the electric device Xmn is restarted is stored in the storage means 2e. If the re-operation device detection means 2d detects the fact that these electric devices Xmn have been re-operated beyond the continuous non-operation period, before displaying the above-mentioned message for notifying the precautions. The image data generation means 2f reads out the operation start correspondence message corresponding to the electric device Xmn from the storage means 2e. The image data for displaying the read message is generated and transmitted to the terminal device TU via the integration device TM, and the operation start correspondence message is displayed on the terminal device TU and then restarted through the above processing. A message indicating precautions may be displayed on the terminal device TU. Here, as the above-mentioned operation start correspondence message, for example, a message such as “I started using the air conditioner is ○ days earlier than last year” or “It became cold (hot)” is displayed. When re-operating the device Xmn, the user can know how long it will take to start using it compared to when it started last time, or whether it will be earlier or later than the start time of normal use. However, if it is desired to delay the start of use from the viewpoint of energy saving, it can be used for such actions. FIG. 11C is an example of a screen that displays an operation start message, and a child screen G2 that displays the message is superimposed on the display screen 72a of the image display unit 72 (pop-up display). The sub-screen G2 displays an operation start message (for example, “the start of using an air conditioner is 10 days earlier than last year”) M2 corresponding to the electrical equipment to be reactivated, and a confirmation button BT12 for performing a confirmation operation. ing.

  Thus, when the air conditioner or floor heating appliance is operated for a long time at the turn of the season or the like, the above-mentioned operation start correspondence message and the message for notifying the warning are displayed on the terminal device TU. The fact that the system grasps history information using Xmn can be notified to the user, and the reliability of the system can be enhanced.

  Moreover, in this system, the control part 2c can grasp | ascertain the electric usage of the electric equipment Xmn connected to each branch breaker Bmn based on the electric usage of each branch breaker Bmn input from the calculating part 2b. If the electric usage amount of the electric device Xmn registered in the list to be monitored exceeds a specified value preset by the user using the terminal device TU or the like, the electric device Xmn is stopped using the electric device controller C1. Can be made. Here, when the electric device Xmn such as an air conditioner or a floor heater is not used for a long period of time, the control unit 2c removes the electric device Xmn from the list. By detecting the restart of these electric devices Xmn, the restarted electric devices can be re-registered in the list.

  In the control unit 2c of the energy management unit 2, the history of the amount of electricity used is limited to, for example, the electric device Xmn (for example, an internet-compatible IH electromagnetic cooker or an internet-compatible washing machine) that is always used at a pace of once a week. Information is stored in the storage means 2e, and when these electric appliances Xmn are used, they are compared with the past electricity consumption stored in the storage means 2e, for example, compared with the same day of the week before. When the electric usage amount increases or decreases with respect to the threshold value of the electric usage amount, the image data generating means 2f generates image data to that effect and transmits it to the terminal device TU via the integration device TM. For example, each branch breaker can be displayed by displaying on the terminal device TU a message such as “electricity consumption has increased by ○% since last Monday”. The increase or decrease of the electricity consumption can notify to the user for each mn. By displaying such a display on the terminal device TU, it is natural that the amount of electricity used changes when the user's life pattern changes, but when there is no change in the life pattern, the electrical equipment The user can review whether or not the electric device Xmn has been used excessively due to forgetting to turn off Xmn or due to special circumstances, which can be used for enlightenment of energy saving.

  Furthermore, in the control unit 2c of the energy management unit 2, when the restarting device detection unit 2d has not detected the electrical device Xmn restarted after the continuous non-operation period, it is registered in advance in the storage unit 2g. Select any message from multiple types of messages (for example, energy-saving information, seasonal messages, and various event information) and read it, and generate message display image data to display the read messages. The message display image data may be transmitted to the terminal device TU via the integration device TM. FIG. 11D is an example of message display image data, and a child screen G3 including the message M3 and the screen title TL1 is displayed in a pop-up on the image display unit 72, and the message M3 is presented to the user. Thus, information useful for energy saving, messages such as seasonal messages (such as the meaning of the calendar), and various event information can be transmitted to the user. Here, the case where the image data of the sub-screen G3 is transmitted from the control unit 2c of the energy management unit 2 has been described, but the content of the sub-screen G3 (for example, a ranking that compares the amount of electricity used with other dwelling units is displayed. In some cases, the center device SV may transmit the image data of the child screen G3 to the terminal device TU via the integrated device TM.

  When the user touches the confirmation button BT14 while the sub-screen G3 is displayed, a confirmation signal generated according to the operation of the confirmation button BT14 is transmitted from the terminal device TU via the integrated device TM. 2, the control unit 2 c receives the confirmation signal transmitted from the terminal device TU, generates power real monitor image data, and transmits the power real monitor image data to the terminal device TU via the integration device TM. Since it is transmitting, the display of the sub-screen G3 can be terminated and switched to the original screen (for example, a power real monitor screen).

  In the above-described embodiment, the terminal device TU has a touch panel, and a desired operation is performed by touching a switch displayed on the screen. However, the operation unit is limited to a touch switch. Instead, a desired operation may be performed using an operation unit provided in the main body of the terminal device TU, and when the terminal device TU is a television, a desired operation may be performed using a television remote controller. good.
