FIG. 2 is a block diagram showing a functional configuration of the support server 8.
As shown in the figure, the support server 8 is roughly divided into a communication unit 30, a database unit 32, a fuel consumption totaling unit 34, a continuous curve calculating unit 36, a usage situation analyzing unit 38, and providing advice. Part 40.
The support server 8 is configured using a general computer system that includes a CPU as a control means, a ROM, a RAM, a hard disk drive as a program storage means, and the like (all not shown). Installation on the hard disk drive is performed by causing the computer system to read various programs including a device usage status program according to the present invention recorded on a recording medium such as a CD-ROM. And various functions shown in Drawing 2 are realized when a computer program runs the program concerned. Further, as described above, the support server 8 has an HTTP server function and is configured to be able to browse a WEB page by the WEB service from the installation terminal 9 of each customer 2.

Explaining each part of the support server 8, the communication unit 30 performs two-way data communication with the installation terminal 9 installed in each customer 2 via the telecommunication line 6.
The database unit 32 stores various types of information, and includes a customer information database 42 and an advice database 44.
The customer information database 42 stores customer information 43 that is information for managing each customer 2.
FIG. 3 is a diagram schematically illustrating an example of the contents of the customer information 43.
As shown in the figure, the customer information 43 includes ID 43A and hot water supply facility information 43B as identification information of the customer 2.
The hot water use facility information 43B stores the hot water use facility 10 provided in the customer 2 as a group. In each of these groups, the value range of the fuel consumption per unit time consumed by the gas water heater 4 when the hot water supply utilization facility 10 is used is defined in advance. In addition, a standard value of fuel consumption per unit time is defined in advance in each hot water use facility 10 by an experimental value or the like, and each hot water use facility 10 is divided into a group of value ranges including the standard value.

In the present embodiment, as the above group, “low consumption equipment” to which the hot water supply facility 10 with relatively low fuel consumption belongs, “high consumption equipment” to which the hot water supply facility 10 with relatively high fuel consumption belongs, and those There are three “medium consumption facilities” to which the hot water supply utilization facility 10 for the amount of fuel consumption belongs.
The “low consumption equipment” group includes, for example, equipment that uses hot water in a relatively low temperature range such as a kitchen or a wash basin. The “high consumption equipment” group includes, for example, hot water for a bathtub or shower. Equipment that uses hot water in a relatively high temperature range generally belongs. In addition, the “medium consumption equipment” group includes, for example, equipment in which hot water is used in a temperature range between a low consumption equipment and a high consumption equipment, such as reheating a bathtub.

Returning to FIG. 2, the advice database 44 stores an energy saving measure advice sentence.
FIG. 4 is a diagram schematically showing the advice database 44.
As shown in the figure, in the advice database 44, a large number of energy saving measure advice sentences 46 describing contents contributing to energy saving measures are registered. One or a plurality of these energy saving measure advice statements 46 are provided for each hot water supply equipment 10, and each of the energy saving measure advice statements 46 defines a parameter 48 for determining whether to provide the energy saving measure advice statement 46. ing. For this parameter 48, either the usage time or the fuel consumption of the hot water supply utilization facility 10 is used according to the function and application of the hot water utilization facility 10 and the distinguishability on the sustain curve described later.

For example, when the hot water supply utilization facility 10 is a bathroom having a cooking function, the cooking time is used for the parameter 48. When the additional cooking use time exceeds a predetermined time, an energy saving measure advice sentence 46 that prompts to refrain from using additional cooking is provided, assuming that excessive use of additional cooking in the bathtub is used.
Further, for example, when the hot water supply facility 10 is a kitchen or a wash basin, the parameter 48 uses the ratio of the fuel consumption of the “low consumption appliance” group, which is the group to which the kitchen belongs, to the total fuel consumption. . When this ratio is high, it is assumed that excessive use of hot water in the kitchen or wash basin is used, and an energy saving measure advice statement 46 is provided that encourages the use of hot water in the kitchen or wash basin and the accompanying fuel consumption. .
Note that one hot water supply utilization facility 10 may use both as the parameter 48 instead of either the usage time or the fuel consumption.

Returning to FIG. 2, the fuel consumption totaling unit 34 acquires and accumulates the fuel consumption and the outside air temperature at the customer 2 every predetermined period (for example, 1 minute) via the communication unit 30.
The regularity determination unit 35 determines whether or not the fluctuation of the fuel consumption over the predetermined number of days is regular based on the detected value of the fuel consumption over a predetermined number of days (for example, for seven days). Such regularity determination will be described later.
The sustain curve calculating unit 36 calculates a fuel consumption sustain curve over a predetermined number of days when the regularity determining unit 35 determines that the regular curve is regular.

Based on the correspondence between the duration curve calculated by the duration curve calculation unit 36 and the value range of the fuel consumption per unit time of each group, the usage situation analysis unit 38 obtains the usage time and the fuel consumption for each group. . Thereby, use time and fuel consumption are calculated | required about the hot water supply utilization equipment 10 of each group.
Based on the usage time and the fuel consumption of each hot water supply facility 10 calculated by the usage situation analysis unit 38, the advice providing unit 40 exceeds the predetermined value of the parameter 48 defined for each hot water supply facility 10 The energy saving measure advice sentence 46 is extracted from the advice database 44, and a WEB page is generated and published so that it can be viewed from the installation terminal 9 of the customer 2.
Moreover, the advice provision part 40 extracts the energy-saving countermeasure advice sentence 46 about all the hot water supply utilization facilities 10 with which the consumer 2 is provided, when it determines with irregularity by the regularity determination part 35, and publishes on a WEB page.

Next, the operation of the support server 8 will be described as the operation of the present embodiment.
FIG. 5 is a flowchart of the device usage status analysis process of the support server 8.
The support server 8 first acquires a detected value of fuel consumption over 7 days (1 week) (step S1). For example, when the fuel consumption amount at the customer 2 is detected every minute, 60 × 24 (= 1440) detection values are acquired per day.
Here, the period of one week is generally a basic unit of human life (minimum period for making a round of each lifestyle on weekdays and holidays). Therefore, by analyzing the fuel consumption over one week, it is possible to perform analysis by taking into account the user's daily activities on weekdays and holidays.

Next, the support server 8 determines whether or not the daily fluctuation of the fuel consumption is irregular due to a factor such as a user staying out based on the detected value of the fuel consumption for 7 days. The fuel consumption regularity determination process is executed as much as possible (step S2).
FIG. 6 is a flowchart showing the fuel consumption regularity determination process.
In this fuel consumption regularity determination process, (1) whether or not the time when fuel consumption peaks on each day is in approximately the same time zone, and (2) the average outside air temperature and total fuel consumption for each day The regularity of daily fluctuations in fuel consumption is determined in two ways: whether the quantity correlation coefficient is in the same range.

That is, the support server 8 calculates the fuel consumption amount for every hour for each day (step S20), and calculates the fluctuation range (blurring range) of the peak time of the fuel consumption amount for each day (step S21). Then, when the fluctuation range is outside the range of the predetermined width α (for example, 3 hours) (step S22: No), the support server 8 determines that there is no regularity in the fluctuation of the fuel consumption amount on the 7th. (Step S23).
On the other hand, when the fluctuation range is within the range of the predetermined width a (step S22: Yes), the support server 8 calculates a correlation coefficient between the fluctuation of the average outside air temperature and the fluctuation of the fuel consumption amount for each day in one week. (Step S24). Then, when the correlation coefficient is equal to or less than the predetermined value β (step S25: No), the support server 8 determines that there is no regularity in the variation of the fuel consumption on the 7th day (step S23), If it is larger than the predetermined value β (step S25: Yes), it is determined that the variation in the fuel consumption is regular (step S26). The predetermined value β is set to such a value that it can be considered that the fuel consumption varies following the variation of the average outside air temperature.

  The fact that there is no regularity in fluctuations in the fuel consumption indicates that there is no regularity in the use of the hot water supply facility 10 by the user for 7 days. Therefore, as shown in FIG. 5, when the support server 8 determines that there is no regularity (step S <b> 3: No), the energy saving measure advice sentence 46 for all the hot water use facilities 10 provided in the customer 2. Is extracted and published on the WEB page (step S4).

On the other hand, when the variation of the fuel consumption is regular (step S3: Yes), the support server 8 creates a fuel consumption duration curve (step S5).
FIG. 7 is a diagram schematically showing the duration curve.
The duration curve is a curve obtained by rearranging the detected values of the fuel consumption in descending order. In the present embodiment, for each detected value of fuel consumption over one week, an average value between the measurement values at the same time on each day (the same measurement value on each day) is calculated, and the average value is used. To calculate the duration curve. This averages the trend of fuel consumption over a week and provides a duration curve based on this averaged trend of fuel consumption.

In this continuous curve, as shown in FIG. 7, corresponding to the value range of fuel consumption per unit time that each group of “high consumption equipment”, “medium consumption equipment” and “low consumption equipment” can take, A curve having a shape whose value is substantially constant or gently fluctuates is obtained.
In this duration curve, the usage time of the group is determined by the length of the range in which the value of the duration curve belongs to the value range of the group, and the fuel consumption consumed by the group in one week by the area of the range Is required.
This makes it possible to analyze the usage status such as which group uses excessive hot water from the usage time and fuel consumption for each group. Furthermore, based on the types and uses of the hot water supply facilities 10 belonging to each group, trends in the use of hot water at the customer 2 such as a long time for additional cooking in the bathtub or a large amount of hot water usage in the kitchen. Can also be estimated.

  Then, after calculating the usage time and fuel consumption of each group (step S6), the support server 8 calculates the value of the parameter 48 defined for each hot water use facility 10 based on the usage time and fuel consumption. Is extracted from the advice database 44 and the WEB page is generated and made public so that it can be viewed from the installation terminal 9 of the customer 2 (step S7). Then, the device usage status analysis process is terminated.

  As explained above, according to this embodiment, based on the continuous curve obtained from the detected value of the fuel consumption at the consumer 2, each usage time and fuel of the hot water supply facility 10 provided in the consumer 2 In order to obtain the consumption amount, it is not necessary to provide a detector for each hot water supply utilization facility 10 to individually detect the fuel consumption amount, and the installation cost and maintenance cost of the system can be suppressed. In addition to this, even when the number of hot water supply utilization facilities 10 is increased, a complicated operation such as attaching a detector as in the prior art becomes unnecessary.

  Moreover, according to this embodiment, it was set as the structure which divides the hot water supply utilization equipment 10 into a some group, and calculates | requires use time and fuel consumption for every group. Thereby, since the usage time and the fuel consumption of each of the hot water supply utilization facilities 10 belonging to the group are obtained at a time, the processing can be shortened.

Furthermore, according to this embodiment, since the regularity of the fluctuation of the fuel consumption in the predetermined number of days is determined, the user 2 is away from the user on a trip or the like in the customer 2 or is not in operation due to a sudden holiday or the like. When the period during which the hot water supply utilization facility 10 is not used is included, or when the use of the hot water utilization facility 10 is not regular due to an irregular life, the variation in the fuel consumption is determined to be irregular. Thereby, when the fluctuation | variation of energy consumption is regular, ie, the case where the normal energy consumption action is performed in the consumer 2, and the case where it is not so, it can distinguish. Accordingly, the use status of the hot water supply facility 10 can be analyzed and energy saving support can be performed.
In particular, according to the present embodiment, the regularity of the fuel consumption is determined based on the correlation between the outside air temperature and the fuel consumption, so that the regularity of the fuel consumption can be determined with higher accuracy.

  In addition, embodiment mentioned above shows the one aspect | mode of this invention to the last, and a deformation | transformation and application are arbitrarily possible within the scope of the present invention.

For example, the detection interval of the fuel consumption at the customer 2 is 1 minute, and the detection period of the fuel consumption used for generating the sustain curve is 1 week, but these can be set as appropriate.
Further, for example, the operation period of the gas water heater 4 used for calculating the fuel consumption of the gas water heater 4 is detected from the fan current of the combustion fan 12, but the present invention is not limited to this. That is, a temperature sensor is provided at the exhaust gas discharge port of the gas water heater 4 to detect the exhaust gas temperature, and the period during which the exhaust gas temperature is higher than the outside air temperature may be set as the operation period of the gas water heater 4.
In addition, it is good also considering the detected value of the gas transaction meter installed by the gas company as fuel consumption.

  Moreover, the gas combustion type water heater was illustrated as the heat source equipment that consumes fuel. However, the fuel is not limited to gas fuel such as gas, but may be liquid fuel such as kerosene or alcohol, or solid fuel such as coal or briquette. The heat source equipment is not limited to a heat source such as a water heater, and may be a cold source.

Moreover, the structure which calculates | requires each usage time and / or power consumption of each of the some electrical appliance (load apparatus) 160 with which the consumer 2 is provided instead of the hot water supply utilization equipment 10 like the energy saving assistance system 101 shown in FIG. It is also good.
In this case, the consumer 2 is provided with a power consumption detector 151 that detects the amount of power used by the consumer 2 by detecting the current flowing through the distribution board 150 instead of the fuel consumption calculation device 16. The detected value of the power consumption is transmitted to the energy saving support server computer (hereinafter referred to as “support server”) 108 via the installation terminal 9 for example every minute.

  In this embodiment, the rated power consumption of the electrical appliance 160 corresponds to the reference value of the hot water supply utilization facility 10, and the support server 108 stores these electrical appliances 160 in groups based on each rated power consumption. . Then, the support server 108 obtains a sustained curve for a predetermined period based on the detected value of power usage from the customer 2, and the value of the sustained curve is based on the range belonging to the value width of the rated power consumption of each group. The usage time and / or power consumption of each appliance 160 belonging to each group is calculated.
