In this case, the measurement device 5 can receive the output of the sensor unit of the power conditioner and measure the amount of power generated by the solar cell (power generation amount), the remaining power amount of the storage battery (remaining capacity), and the like. it can. Thus, the electric power (instantaneous electric power, electric energy) measured by the measurement device 5 is related information related to energy in the house, and the measurement device 5 is an information providing device that provides the management device 2 with related information. Function. The measuring device 5 is installed side by side with the distribution board 4. However, the measuring device 5 is not limited to this configuration and is housed in the distribution board 4 together with other internal devices (main circuit breaker or branch breaker). May be.

  As shown in FIG. 1, the management device 2 communicates between the processing unit 21 that performs a process of providing presentation information to the television 3, the presentation information storage unit 22 that stores the presentation information and the like, and the television 3. And a television communication unit 23 for performing.

  In response to a request from the determination unit 27 described later, the processing unit 21 reads the presentation information from the presentation information storage unit 22 and provides it to the television 3 to display the presentation information on the television 3. Here, the processing unit 21 has a function as a Web server that provides the presentation information, and the television 3 has a function as a Web browser that browses the presentation information provided from the processing unit 21.

  The television 3 displays the presentation information provided from the management device 2 on a part of the screen (for example, the lower right corner). Specifically, the television 3 displays the presentation information so as to overlap with a part of the content being viewed and received by, for example, receiving a television broadcast. The content here is a video displayed on the television 3 for the purpose of viewing by the user, and is displayed not only by the television broadcast but also by input to the television 3 from an external device (such as a DVD player or a game machine). Also included is a video to be played. The display form of the presentation information is not limited to the above form. For example, the presentation information may be displayed side by side with the content being viewed and reduced. Alternatively, the display of content may be temporarily interrupted, and the presentation information may be displayed on the entire screen of the television 3.

  The management device 2 includes an information acquisition unit 24 that acquires the measurement result of the measurement device 5 as related information, a related information storage unit 25 that stores the related information, and a measurement communication unit 26 that communicates with the measurement device 5. It has further.

  The information acquisition unit 24 acquires related information periodically (for example, every 5 minutes), and stores the acquired related information in the related information storage unit 25 in time series. In the related information storage unit 25, as exemplified in Table 1 below, for each “circuit ID” for specifying the load, “circuit name”, related information (“instantaneous power consumption” in Table 1), The measurement date and time ("Measurement time stamp" in Table 1) is stored in association with each other.

すなわち、表１では、たとえば回路ＩＤが「ＣＩ００１」である主幹回路について、２０１１年２月１８日１４時１５分の時点で、１５００Ｗの電力（瞬時値）が消費されていたことを表している。

That is, Table 1 shows that 1500 W of power (instantaneous value) was consumed at 14:15 on February 18, 2011 for the trunk circuit whose circuit ID is “CI001”, for example. .

  In the present embodiment, the management device 2 constructs a local area network (LAN) using a general-purpose communication protocol in a house together with the television 3 and the measurement device 5. Between the television 3 and the management device (television communication unit 23) 2 and between the measurement device 5 and the management device (measurement communication unit 26) 2 may be wired by a LAN cable, or by a wireless LAN. Wireless connection may be used. In this embodiment, as an example, the television 3 and the management device 2 are connected by wire, and the measurement device 5 and the management device 2 are connected wirelessly. Note that these connection forms are not limited to LAN connection, and for example, a connection form conforming to a standard such as HDMI (High-Definition Multimedia Interface) may be used between the television 3 and the management device (the television communication unit 23) 2. .

  The management device 2 further includes a determination unit 27 that determines whether or not the related information satisfies a predetermined determination condition, and a condition storage unit 28 that stores the determination condition.

  The determination unit 27 determines whether or not the related information satisfies the determination condition by comparing the related information read from the related information storage unit 25 with the determination condition read from the condition storage unit 28. The condition storage unit 28 stores a plurality of determination conditions in advance. The determination unit 27 makes a determination every time the information acquisition unit 24 acquires related information. When the determination unit 27 determines that the related information satisfies the determination condition, the determination unit 27 issues a request (transmission request) to the processing unit 21. A process for displaying the presentation information is executed. In the condition storage unit 28, as exemplified in Table 2 below, for each “condition ID” for specifying the determination condition, a “condition sentence” indicating the determination condition and the contents of the conditional sentence are described in a sentence “ “Remarks” is stored in association with each other.

すなわち、表２の例では、たとえば回路ＩＤが「ＣＩ００１」で特定される負荷の消費電力（瞬時値）が２０００Ｗを超えたときに、判定部２７は条件ＩＤが「ＣＯ００１」である判定条件を満たした（つまり、関連情報が判定条件に合致した）と判定する。

That is, in the example of Table 2, for example, when the power consumption (instantaneous value) of the load specified by the circuit ID “CI001” exceeds 2000 W, the determination unit 27 sets the determination condition that the condition ID is “CO001”. It is determined that the condition is satisfied (that is, the related information matches the determination condition).

  The transmission request output from the determination unit 27 to the processing unit 21 includes a condition ID that specifies the determination condition determined to be matched by the determination unit 27, and the processing unit 21 provides the presentation information corresponding to the condition ID. Is read from the presentation information storage unit 22 and provided to the television 3. That is, the presentation information storage unit 22 stores the presentation information as a presentation information table 221 in association with the condition ID, and the processing unit 21 provides the television 3 with presentation information corresponding to the condition ID included in the transmission request. To do. The presentation information table 221 includes a “condition ID” and a “message wording” indicating the content of the presentation information for each “message ID” for specifying the presentation information, as shown in Table 3 below. A “presentation information type” indicating a display format of information is stored in association with each other.

すなわち、表３の例では、たとえば条件ＩＤが「ＣＯ００５」である判定条件を満たしたとき、処理部２１は、「太陽光の発電が開始されました」というテキストからなる提示情報（メッセージＩＤが「ＭＥ００２」の提示情報）をテレビ３に提供する。

That is, in the example of Table 3, for example, when the determination condition that the condition ID is “CO005” is satisfied, the processing unit 21 presents the presentation information (message ID is the message “Solar power generation has started”). (Presentation information “ME002”) is provided to the television 3.

  In addition to the condition ID, the transmission request output from the determination unit 27 to the processing unit 21 may include related information that matches the determination condition, a circuit ID that identifies the load, and the like. In this case, for example, the processing unit 21 uses the related information and the circuit ID included in the transmission request to generate presentation information that represents the current power consumption and the power consumption of the day for each load, and provides the presentation information to the television 3. Is also possible. Thus, the presentation information generated based on the related information may include a graph representing the current power consumption in addition to the text.

  In addition, although the management apparatus 2 may be comprised so that control of charging / discharging of a storage battery and on / off control of each load may be possible in the process part 21, the detail about these controls by the process part 21 is possible. The detailed explanation is omitted. The processing unit 21, the information acquisition unit 24, and the determination unit 27, which are main functions of the management device 2, are realized mainly by a microcomputer.

  By the way, in the energy management system 1 of the present embodiment, the television 3 displays the presentation information triggered by the fact that the type of the content currently being viewed matches a predetermined display condition. In other words, the television 3 determines the timing for displaying the presentation information in accordance with the type of the content being viewed. Even when the management device 1 provides the presentation information, the type of the content being viewed is determined. The presentation information is not displayed until the display condition is satisfied. The type of content here is displayed, for example, by the name of the program being viewed or the genre of the program, whether it is a CM (commercial message), the genre or content of the CM, or input from a DVD player, game machine, or the like. Including whether or not the screen is a screen.

  More specifically, the presentation information storage unit 22 stores display conditions in association with the presentation information as an attribute table 222. When the processing unit 21 reads the presentation information from the presentation information storage unit 22, The display conditions associated in the table 222 are read together. The processing unit 21 combines the presentation information read from the presentation information storage unit 22 and the display conditions, and transmits the communication data from the television communication unit 23 to the television 3. If the transmission request from the determination unit 27 to the processing unit 21 includes related information, circuit ID, or the like, the processing unit 21 converts the information such as related information or circuit ID into communication data as necessary. May be included.

  The television 3 includes a device communication unit 31 that communicates with the television communication unit 23 of the management device 2 and a display control unit 32 that displays the presentation information. The presentation information transmitted from the management device 2 and Communication data including display conditions is received by the device communication unit 31. Furthermore, the television 3 includes a timing determination unit 33 that determines whether or not the type of the content being viewed matches the display condition, and displays the presentation information when the content matches the display condition. When the communication data is received by the device communication unit 31, the timing determination unit 33 is included in the communication data when the type of content currently being viewed matches the display condition included in the communication data. Display information is displayed on the display control unit 32.

  Here, the television 3 temporarily stores the communication data received from the management device 2 in the memory 34. The television 3 collates the type of content being viewed with the display conditions in the memory 34 at any time by the timing determination unit 33, and if the type of content being viewed matches the display conditions, display control of the presentation information in the memory 34 is performed. This is displayed on the part 32. Note that for the presentation information for which display conditions are not specified (shown as “-” in Table 4 below), the television 3 displays the presentation information immediately after receiving the communication data.

  Here, as illustrated in Table 4 below, as the attribute table 222, “priority”, “emergency”, “display condition”, and “time limit” are associated with each “message ID”. Is memorized.

すなわち、表４の例では、たとえばメッセージＩＤが「ＭＥ００２」である提示情報については、テレビ３で視聴中のコンテンツの種別が「ＣＭ」という表示条件に合致したときにテレビ３に提示情報が表示されることになる。表４中の「優先度」並びに「緊急度」は、処理部２１によって提示情報記憶部２２から提示情報および表示条件と一緒に読み出され、提示情報および表示条件と組み合わされて通信データとしてテレビ通信部２３からテレビ３に送信される。

That is, in the example of Table 4, for example, for the presentation information whose message ID is “ME002”, the presentation information is displayed on the television 3 when the type of content being viewed on the television 3 matches the display condition “CM”. Will be. The “priority” and “emergency” in Table 4 are read together with the presentation information and the display condition from the presentation information storage unit 22 by the processing unit 21 and combined with the presentation information and the display condition as television data as communication data. The data is transmitted from the communication unit 23 to the television 3.

  The “priority” in Table 4 is a number indicating the order in which the presentation information is displayed when a plurality of pieces of presentation information are simultaneously displayed. Here, the smaller the number, the higher the priority. Represents. That is, the presentation information of “ME003” and the presentation information of “ME004” in Table 4 have the same display condition, so that it may occur that the display condition is satisfied at the same time. In such a case, since the presentation information “ME003” has the priority “2” in the presentation information “ME003” and the presentation information “ME004”, the presentation information “ME004” has the priority “3”. Is also displayed first. Here, in the configuration in which the time for displaying each piece of presentation information is determined in advance and the television 3 sequentially displays the presentation information having a high priority, the television 3 displays the next presentation information every time this time elapses.

  “Emergency” in Table 4 is a number indicating the urgency and importance of the presented information. Here, the smaller the number, the higher the urgency. Specifically, regarding the presentation information with the urgency “1”, the television 3 is turned on automatically by displaying the presentation information by turning on automatically even in the standby (standby) state where the screen is not displayed. Regardless of the state or standby state, the presentation information is displayed immediately after receiving the communication data. Regarding the presentation information with the urgency “2”, the television 3 displays the presentation information immediately after receiving the communication data, only when the television 3 is in the on state, regardless of the type of the content being viewed.

  Regarding the presentation information with the urgency level “3”, the television 3 displays the presentation information if the type of the content being viewed matches the display condition without any particular time limitation. Regarding the presentation information with the urgency level “4”, the television 3 displays the presentation information if the type of the content being viewed matches the display conditions, and even if a predetermined time limit has elapsed after receiving the communication data. If the display conditions are not met, the presentation information is deleted from the memory 34 without being displayed. In the example of Table 4, since the time limit is set to “1 hour” for the presentation information of “ME004” having the urgency “4”, the television 3 is within one hour after receiving the communication data. Only when the content type matches the display condition, the presentation information “ME004” is displayed. Regarding the presentation information with the urgency “5”, the television 3 displays the presentation information if the type of the content being viewed matches the display condition when the communication data is received, and displays the presentation information in the memory 34 if it does not match. Discard without memorizing.

  Thus, regarding the presentation information with a high degree of urgency (“1” or “2”), the television 3 displays the presentation information regardless of the type of content being viewed. For presentation information with a low degree of urgency (“4” or “5”), the television 3 displays the presentation information with a time restriction in addition to the type of content being viewed.

  Note that the television 3 may identify the type of content being viewed based on data included in an EPG (electronic program guide) or a television broadcast reception signal, or by analyzing audio or video. May be.

  In addition, the presentation information displayed on the television 3 by the management device 2 is not limited to the information as described above, and may be information such as an electricity bill (unit price) in the current time zone, or a prediction of the power generation amount of the solar cell of the day. . In this case, the management device 2 is connected to the Internet, and acquires related information such as electricity charges and weather used for power generation amount prediction from a server on the Internet by the information acquisition unit 24. In this configuration, a server on the Internet functions as an information providing device that provides related information to the management device 2.

  Next, the operation of the energy management system 1 will be described with reference to FIG. 3 showing the operation of the management device 2 and FIG. 4 showing the operation of the television 3.

  The management device 2 periodically acquires related information from the measuring device 5 by the information acquisition unit 24, and accumulates the acquired related information in the related information storage unit 25 (S1). Each time the management device 2 stores the acquired related information in the related information storage unit 25, the determination unit 27 uses the determination condition stored in the condition storage unit 28 to store the related information in the related information storage unit 25. A determination is made (S2). As a result, if there is no matching determination condition (S3: NO), the management device 2 returns to the process of S1.

  On the other hand, if there is a matching determination condition (S3: YES), the management device 2 outputs a transmission request including a condition ID for specifying the determination condition from the determination unit 27 to the processing unit 21 (S4). Receiving the transmission request, the processing unit 21 reads the presentation information corresponding to the condition ID in the transmission request from the presentation information storage unit 22 and provides it to the television 3 (S5). At this time, the processing unit 21 reads the display condition associated with the attribute table 222 together with the presentation information, and transmits it from the television communication unit 23 to the television 3 as communication data in combination with the presentation information.

  When the communication data is received by the apparatus communication unit 31 (S11), the television 3 reads the display conditions in the communication data by the timing determination unit 33 (S12), and the type of content currently being viewed matches the display conditions. It is determined whether or not (S13). If the content being viewed does not match the display condition (S13: NO), the timing determination unit 33 puts the display process of the presentation information on hold and temporarily stores the presentation information together with the display condition in the memory 34 (S14).

  On the other hand, if the content being viewed matches the display conditions (S13: YES), the timing determination unit 33 displays the presentation information corresponding to the display conditions (S17). At this time, if there are a plurality of presentation information corresponding to the same display condition (S15: YES), the timing determination unit 33 rearranges the presentation information in order from the presentation information with the highest priority (S16). The presentation information is sequentially displayed (S17).

  If the urgency level is included in the communication data from the management device 2, the timing determination unit 33 reads the urgency level together with the display condition. Depending on the urgency level, whether the currently viewed content matches the display condition. The presenting information is immediately displayed without determining whether or not (S13) (S17).

  According to the management device 2 having the configuration described above, the presentation information based on the related information related to energy (electric power) is displayed on the television 3 by the push method, so that the user sees the screen of the television 3 and relates to the energy. Information to do. When displaying this type of presentation information, immediacy is not important, but it is required to display it at a position that is easy to enter the user's field of view. Therefore, the television 3 that easily enters the user's field of view is suitable as a medium for displaying the presentation information.

  Here, since the presentation information is displayed with a trigger that the type of content being viewed on the television 3 matches the display condition, the display of the presentation information hinders the original function of the television 3 for viewing a television broadcast. Hateful. That is, when the presentation information is displayed regardless of the type of content being viewed, the user may feel annoyed by the act of viewing the television 3, whereas in the present embodiment, the presentation information is displayed. The content type can be specified. Therefore, the management device 2 has an advantage that, for example, the presentation information is displayed only during the CM, so that it does not hinder the viewing of the television broadcast, and it is difficult for the user who is viewing the television broadcast to be bothered. .

  The presentation information storage unit 22 stores a plurality of pieces of presentation information in association with content types (display conditions) on the attribute table 222, and the timing determination unit 33 displays the display conditions that match the content types. The presentation information to be displayed is selected from a plurality. Thereby, the content of the presentation information displayed on the television 3 is optimized according to the type of content being viewed on the television 3. That is, not only the timing at which the presentation information is displayed, but also the content of the displayed presentation information is determined according to the type of content being viewed on the television 3. Therefore, the content of the presentation information presented to the user changes according to the type of content being viewed on the television 3, and there is an advantage that it is less likely to bother the user who is viewing the television broadcast.

  For example, regarding the presentation information whose corresponding determination condition on the attribute table 222 is “CM” or “news program”, the presentation information table 221 has different contents (messages) for each type of “CM” and “news program”. Use word) may be associated. In this case, the correspondence between the content type and the content of the presentation information is read by the processing unit 21 from the presentation information storage unit 22 together with the display condition, and is combined with the display condition as communication data from the television communication unit 23. It is transmitted to the television 3. When the type of content being viewed satisfies the display condition, the timing determination unit 33 displays the presentation information of the content corresponding to the type of content currently being viewed.

  Furthermore, the timing determination unit 33 sequentially displays each presentation information according to the priority associated with each presentation information on the attribute table 222 when a plurality of pieces of presentation information satisfy the display condition and become display targets. Display. For this reason, while individually displaying a plurality of pieces of presentation information, by associating a higher priority with presentation information that requires immediacy, the television 3 can display presentation information that requires immediacy as much as possible without delay. It can be presented to the user.

  In the present embodiment, the management device 2 transmits communication data including presentation information and display conditions to the television 3, and the determination of the timing for displaying the presentation information, that is, the type of content being viewed is used as the display condition. The timing determination unit 33 of the television 3 determines whether or not they match. Accordingly, it is only necessary to transmit communication data unilaterally from the management device 2 to the television 3 between the management device 2 and the television 3, and it is not necessary to perform bidirectional communication. Simplification and improvement in communication speed can be achieved.

  By the way, the energy management system 1 of this embodiment has an importance storage unit (not shown) in which the importance associated with each presentation information and the importance associated with each content type are stored in advance. And the timing determination unit 33 may use the importance as a display condition.

  In this case, the timing determination unit 33 displays the presentation information based on the magnitude relationship of the importance so that the presentation information is displayed when the importance of the type of the content being viewed falls below the importance of the presentation information. Make timing decisions. In other words, when the importance corresponding to the type of content being viewed falls below the importance of the presentation information, the timing determination unit 33 determines that the type of content being viewed matches the display conditions, indicate. In short, the timing determination unit 33 refers to the importance storage unit, grasps the importance of the content being viewed, and displays the presentation information having a higher importance than the importance.

  As illustrated in Table 5 below, the importance storage unit stores “importance” associated with each of “message ID” and “content type”. The “importance” in Table 5 is a number indicating the urgency and importance of the presentation information and content, and here, the smaller the number, the higher the importance. The importance in the importance storage unit can be arbitrarily changed by the user.

すなわち、表５の例では、たとえばメッセージＩＤが「ＭＥ００２」の提示情報については、重要度が「３」であるため、テレビ３で視聴中のコンテンツの種別が優先度「４」以下のときにテレビ３に提示情報が表示されることになる。要するに、タイミング判断部３３は、テレビ３で視聴中のコンテンツの種別が重要度「４」または「５」である「ＣＭ中」、「ニュース番組」、「バラエティ番組」のいずれかに該当すれば、表示条件に合致すると判断して「ＭＥ００２」の提示情報を表示させる。

That is, in the example of Table 5, for example, for the presentation information with the message ID “ME002”, the importance is “3”, and therefore the type of content being viewed on the television 3 is the priority “4” or less. The presentation information is displayed on the television 3. In short, if the type of the content being viewed on the television 3 corresponds to any of “CM”, “News program”, and “Variety program” with the importance level “4” or “5”, the timing determination unit 33 corresponds. The display information “ME002” is displayed on the assumption that the display condition is met.

  According to this configuration, the timing determination unit 33 compares the importance level between the content being viewed and the presentation information, and displays the presentation information display timing so that the higher importance level is preferentially displayed. To decide. Therefore, since the timing determination unit 33 can display the presentation information on the television 3 according to the importance, there is an advantage that information requiring immediacy can be notified to the user without delay.

  Here, in the energy management system 1 of the present embodiment, the management device 2 transmits communication data including presentation information and display conditions to the television 3, and the timing determination unit 33 of the television 3 determines the timing for displaying the presentation information. Done in Therefore, the importance level storage unit may be provided separately for the management device 2 and the television 3. For example, the correspondence between the presentation information and the importance may be stored in the presentation information storage unit 22 of the management device 2, and the correspondence between the content type and the importance may be stored in the television 3.

  As a result, if the management device 2 includes the presentation information together with the presentation information as the display condition in the communication data and transmits it to the television 3, the timing determination unit 33 of the television 3 determines that the type of the content being viewed is within the communication data. It can be determined whether or not the display conditions are met. That is, the timing determination unit 33 refers to the importance level storage unit to grasp the importance level of the content being viewed, and if the importance level (display condition) in the communication data is higher than the recognized importance level, the communication data The presentation information inside is displayed.

  Moreover, even if the information acquisition part 24 of the management apparatus 2 is the structure which acquires the operation state of an electric equipment, a hot water supply installation, a solar power generation facility, etc. by communication, and acquires the relevant information regarding energy based on this operation state. Good.

  Note that the television 3 may have a time restriction on the display of the presentation information regardless of the degree of urgency. In this case, the television 3 deletes the presentation information from the memory 34 without displaying the presentation information if the type of the content being viewed does not meet the display conditions even after a predetermined effective time has elapsed after receiving the communication data.
