  Next, a specific configuration of the residential energy system according to the embodiment of the present invention will be described. FIG. 2 is a block diagram showing an example of a schematic configuration of the residential energy system 10 according to the embodiment of the present invention.

  As shown in FIG. 2, the house energy system 10 includes a control device 20 that corresponds to the above-described calculation unit 16 and that monitors and controls energy in the house. The control device 20 includes a microcomputer. That is, the control device 20 includes a CPU 22, a ROM 24, a RAM 26, and an input / output port 28, which are connected via a bus 30 such as an address bus, a data bus, and a control bus.

  A display device 32, an operation device 34, a flash memory 36, and the like are connected to the input / output port 28 as various input / output devices, and a power supply unit 38 that supplies power to each unit is connected.

  For example, a display such as a liquid crystal can be applied to the display device 32. The operation device 34 may be a touch panel provided integrally with the display device 32, or may be an operation device such as a keyboard. That is, the display device 32 and the operation device 34 function as the display / operation unit 12 described above.

  The flash memory 36 functions as the data storage unit 18 described above, and stores a detection result of energy consumption in a house, an energy saving support program that supports energy consumption reduction activities, various information, and the like.

  The power supply unit 38 supplies power to each unit such as the CPU 22, and can stop power supply to a part as in a sleep mode or the like under the control of the CPU 22.

  An analog / digital (A / D) conversion unit 40 is connected to the input / output port 28. The A / D conversion unit 40 converts a detection result of an analog signal output from a sensor for detecting energy consumption of a house or a sensor for detecting information for classifying energy consumption of a house into a digital signal. Thus, the detection result of each sensor is taken into the control device 20.

  Specifically, the A / D converter 40 includes a current sensor 42 that detects a current value consumed in the house, a gas sensor 44 that detects a gas amount consumed in the house, and a water amount consumed in the house.

That is, various sensors connected to the A / D conversion unit 40 function as the above-described detection unit 14. In addition, each sensor is not restricted to the above, For example, you may make it provide the power sensor etc. which detect power consumption.

  Here, the energy consumption reduction support method performed in the residential energy system 10 according to the embodiment of the present invention configured as described above will be described.

  In the residential energy system 10 according to the embodiment of the present invention, the above-described detection units (current sensor 42, gas sensor 44, water sensor 46, solar radiation sensor 48, outside air temperature sensor 50, room temperature sensor 52, wind direction / wind speed sensor 54, outside The detection result of each sensor 14 such as the humidity sensor 51 and the indoor humidity sensor 53) is acquired, and the energy consumption in the house is classified into a predetermined category and stored. Then, past energy consumption classified and stored is used as an evaluation value, and the energy consumption improvement point is advised by comparing it with the current energy consumption.

  As a classification method, for example, based on a predetermined classification specifying parameter shown in FIG. 3A, classification into a predetermined category (A to C in FIG. 3B) as shown in FIG. 3B. Then, energy consumption (for example, current consumption, gas consumption, water consumption, etc.) is stored in the flash memory 36 as the data storage unit 18 for each classification. At this time, as shown in FIG. 3 (B), the energy consumption classified and stored is sorted and stored as an evaluation value table in ascending order of consumption, thereby detecting the energy consumption (actual value) detected next. Compared to the above, by displaying the rank and the like, the reduction of energy consumption is promoted.

  In addition, as an evaluation value table, it is good also as an evaluation value by memorize | storing an actual value as an evaluation value at any time, or memorize | stores a predetermined value as an evaluation value and updates a predetermined value sequentially based on an actual value You may make it do.

  In addition, when energy consumption is classified using the classification specifying parameter in FIG. 3A, it is possible that all of the classification conditions do not match. Therefore, an evaluation value obtained by multiplying a predetermined coefficient or the like You may make it handle as a table.

  Further, the classification specifying parameter shown in FIG. 3A is an example, and is not limited to this, and other parameters may be used. For example, in FIG. 3A, the weather (temperature, solar radiation time, wind direction / velocity) is given as an example of the season / weather content of the classification specifying parameter, but the weather (temperature, humidity, solar radiation time, solar radiation amount) is shown. , Wind direction / wind speed) and the like may be set.

  Then, the specific process performed with the control apparatus 20 which functions as a calculating part of the house energy system 10 concerning the embodiment of the present invention constituted as mentioned above is explained. FIG. 4 is a flowchart showing an example of the flow of processing performed by the control device 20 of the residential energy system 10 according to the embodiment of the present invention.

  In step 100, a predetermined classification information input screen is displayed on the display device 32, and the process proceeds to step 102. That is, a screen for inputting classification information for specifying a classification of energy consumption is displayed, and input is performed according to the display. For example, as the contents to be input, items that cannot be detected by various sensors among the items of the classification specifying parameters are input. Of the classification specifying parameters, items that can be detected by various sensors are acquired and used in subsequent processing.

  In step 102, it is determined whether or not the input has been completed, and the process waits until the determination is affirmed and the process proceeds to step 104.

  In step 104, various detection data are acquired, and the process proceeds to step 106. That is, the detection results of the current sensor 42, gas sensor 44, water sensor 46, solar radiation sensor 48, outside air temperature sensor 50, room temperature sensor 52, wind direction / wind speed sensor 54, outside humidity sensor 51, indoor humidity sensor 53, etc. are A / D. Information for identifying energy consumption and classification is acquired by converting the digital signal into a digital signal by the conversion unit 40 and acquiring the digital signal.

  In step 106, a classification specifying operation is performed, and the routine proceeds to step 108. The classification specifying operation specifies a classification based on the classification information input in the above step and the detection results of various sensors. That is, the control device 20 specifies which category falls into the predetermined category.

  In step 108, an evaluation value is calculated, and the process proceeds to step 110. The calculation of the evaluation value uses the energy consumption detected by each sensor functioning as the detection unit 14 as the evaluation value. If the classification does not match, as described above, the evaluation value may be obtained by multiplying the energy consumption by a predetermined coefficient in order to match the classification with the close category.

  In step 110, an evaluation value table corresponding to the specified category is acquired from the flash memory 36 as the data storage unit 18, and the process proceeds to step 112.

  In step 112, the calculated evaluation value is compared with the acquired evaluation value table, and advice on energy saving is calculated, and the process proceeds to step 114. In other words, the calculated evaluation value is compared with an evaluation value table that is past data, and a ranking is determined. Then, advice in consideration of classification or the like is prepared in advance, and the advice is obtained by selecting the corresponding advice. As advice, for example, by comparing the current consumption energy detected by each sensor with the evaluation value table, it is possible to save energy when the temperature consumption is XX degrees, the sunshine duration is XX, and the energy consumption is XX. It is good, but it is possible to judge that it is bad for energy saving when the energy consumption is xx when the temperature is xx and sunshine time xx, and this data is temperature xx degrees, sunshine time Because XX and energy consumption is close to XX, it is good to save energy when the temperature is XX degrees, sunshine duration is XX, and energy consumption is XX, so please adjust by turning off the heating. Such advice may be stored in advance in the flash memory 36 or the like and selected and displayed on the display device 32.

  In step 114, the comparison result is displayed on the display device 32 that functions as the display / operation unit 12, and the process proceeds to step 116. That is, since a comparison result with past energy consumption and advice regarding energy saving are displayed, reduction of energy consumption such as power saving can be promoted, and support for promoting energy saving can be performed. Further, in this embodiment, by comparing energy consumption for each predetermined category, it is possible to make a comparison in accordance with conditions, so that reduction of energy consumption can be accurately promoted.

  In step 116, the evaluation value table stored in the flash memory 36 is updated, and the series of processes is terminated. That is, the evaluation value table is updated by reflecting the comparison result of step 112.

  In the above embodiment, the case where energy consumption in one house is detected to support energy saving has been described. However, the present invention is not limited to this, and each house can be detected by detecting energy consumption in a plurality of houses. It is good also as a structure which supports energy saving.

Separately from this, the server 60 aggregates the detection results of the detection unit 14 in each house, creates an evaluation value table for each house, and compares the energy consumption of energy with a classification specific parameter that matches or is close. Reduction may be promoted.

  For example, the consumption current of house A is ○, the consumption gas amount is ○, the consumption water amount is ○, the consumption current of house B is Δ, the consumption gas amount is Δ, the consumption water amount is Δ, and the consumption current of C house is ×, The evaluation value table is stored in the server 60 for each house with the consumption gas amount being x and the consumption water amount being x, and the control device 20 of the D house whose classification specifying parameter is similar to that of the A house When making an acquisition request, the server 60 uses the evaluation value table for house A (for example, a detection result of energy consumption such as current consumption is ◯, gas consumption is ◯, water consumption is ◯, etc.) 20 is transmitted. Then, in the control device 20 of D home, the energy consumption detected by the detection unit 14 of D home is compared with the evaluation value table of A home received from the server 60, and there is much energy consumption for the A home, or It is possible to display advice such as less. Alternatively, when there are a plurality of similar houses, it is possible to display the rank and the like, and further promote the reduction of energy consumption. In addition, when transmitting the evaluation value table or the like of another house to the requesting control device 20, the server 60 can protect privacy by transmitting which house information is undisclosed. it can.

  In addition, when selecting a house having a similar classification specification parameter from a plurality of house evaluation value tables, the corresponding house may be selected according to a predetermined priority order.
