Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric power monitoring system for actively promoting energy saving, and an energy saving system using a so-called eco-fund for a company which is actively working on environmental issues. The present invention relates to a power promotion system and a power saving promotion method.

[0002]

2. Description of the Related Art In recent years, due to the emergence of global warming phenomenon and depletion of energy, energy saving consciousness has been increasing in recent years. Although energy demand is steadily increasing worldwide, it is difficult to add new nuclear power plants due to opposition from environmental NGOs. Rather, it can be said that developed countries are moving away from nuclear power plants.
In such a situation, effective use of limited energy is also an important issue in ordinary households. However, a small number of consumers are conscious of energy saving and are working hard to save power, and many consumers are aware of energy saving but have not yet actively implemented it.

Therefore, various conventional techniques for energy saving in general households have been proposed.

For example, Japanese Patent Application Laid-Open No. 2000-3144752 discloses a power monitoring system configured so that the instantaneous value and integrated value of DC power generation and AC power consumption at home can be monitored in real time and visually. (This is referred to as prior art 1). According to this conventional technique, it is easy to compare the power between the power used and the private power generation, so that the power consumption can be easily managed.

Japanese Patent Application Laid-Open No. 11-237414 discloses an electric power monitoring information having a configuration in which an alternating current value is measured and processed and the measurement result is continuously displayed on a monitor such as a home television screen. A terminal is described (this is referred to as conventional technology 2). According to this conventional technique, since information on power consumption can be displayed in an easy-to-view form, it is possible to alert consumers to energy saving.

In Japanese Patent Application Laid-Open No. 11-118844, an indirect power detection means capable of indirectly detecting the power in use is installed on the indoor side wiring section of the distribution board, and the detection result of the indirect power detection means is provided. There is described a power usage state display device configured to display the power consumption and the power rate based on the above (this is referred to as Conventional Technique 3). According to this conventional technique, the current power usage state can be accurately grasped, and effective power saving management can be performed.

Further, Japanese Patent Application Laid-Open No. 9-84146 discloses that
There is described a power management system configured to issue a warning message to a consumer when the contracted power amount is about to be exceeded (this is referred to as prior art 4). According to this conventional technique, it is possible to solve the problem that the breaker falls due to the contracted electric energy.

[0008]

However, the prior art 1 is troublesome because the power consumption must be confirmed on the Internet screen, and the data is one time.
There was a problem that the current situation could not be checked in real time because the message was sent only with a time delay. Further, there is no bench data to be compared, so that it is not possible to confirm how much energy is being realized.

The prior art 2 is troublesome because the user has to turn on the television when he or she wants to see the power consumption. Also, since there is no bench data to compare, it is difficult to determine how much energy saving is realized. There was a problem that it could not be confirmed.

In the case of the prior art 3, there is no bench data to be compared, so that there is a problem that it is not possible to confirm how much energy is saved.

The prior art 4 has a problem in that a warning is issued only when the contracted electric energy is about to be exceeded, so that awareness of energy saving is not raised. Also,
There was also a problem that it was not possible to confirm how much energy was saved because there was no bench data to compare.

Further, any of the above prior arts 1 to 4
It only depends on providing various kinds of information on power consumption to consumers, and whether or not to realize energy saving by using the provided information depends solely on the level of awareness of energy saving of the consumers themselves. For this reason, there is a problem that it is difficult for consumers who are not so conscious of energy saving to effectively utilize the information and save energy even if various information regarding power consumption is provided. This is due to the fact that even if energy saving is achieved, the result cannot be visually recognized as its own benefit.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its purpose is to return the result of realizing energy saving to a power consumer in a visible form as a financial product, thereby reducing energy saving awareness. It is an object of the present invention to provide a power monitoring system, a power saving promotion system using financial products, and a power saving promotion method that can give a high energy saving consciousness even to ordinary consumers who are not expensive.

In FIG. 3, the transition graph display window 53 shows the transition of the power consumption on the day (shown by a solid line in the figure).
Is displayed in comparison with the estimated power consumption (indicated by a broken line in the figure). Then, in this display state, when the changeover switch 53a is pressed once, the transition graph display window 53 displays the transition of the power consumption of the current month as indicated by reference numeral 531 (shown by a solid line in the figure). ) Is displayed in comparison with the estimated power consumption (indicated by a broken line in the figure). Then, in this display state, when the changeover switch 53a is pressed once, in the present embodiment, as indicated by reference numeral 532 next to the switch, the transition graph display window 53 displays the holding of financial products described below up to the present. A graph showing the amount of money, the progress of the purchase amount of the financial product, and the progress of the market value of the financial product is displayed. When the changeover switch 53a is pressed once in this display state, the transition graph display window 53 displays again the transition of the power consumption of the day (shown by a solid line in the figure) and the estimated power consumption (in the figure, (Indicated by a broken line) is displayed.

It should be noted that the information about the financial product indicated by reference numeral 532 is transmitted from
5 may be acquired and transmitted to the power measuring device 11 in the power consumer's home 1, or may be directly transmitted from the terminal device 15 to the power measuring device 11.

Next, the processing operation in the power saving promotion system having the above configuration will be specifically described.

As described above, the management apparatus 12 determines a plurality of scheduled power consumptions B (see FIG. 2) as benchmarks for each power consumer home 1 for the purpose of reducing power consumption. The method of determination has already been described, and a description thereof will be omitted. The power consumer selects one from the determined plurality of scheduled power consumptions B.

The management center that manages the management device 12 gives advice on energy saving know-how according to the estimated power consumption B selected by the power consumer. As a method for giving advice, there is a method using a telephone or a facsimile, but it is also possible to transmit know-how information on energy saving from the management device 12 to the power measurement device 11 and display it on the display unit 11a. As power consumers learn energy-saving know-how, benchmarks can be changed from moderate to severe (or vice versa).

The management device 12 monitors the power consumption of the power consumer home 1 and performs the following three types of calculation processing.

The first is to calculate the difference between the power consumption of the power consumer home 1 in the unit of the day of the day and the scheduled power consumption of the scheduled power consumption B at the corresponding time in the corresponding day among the scheduled power consumption B ( Hereinafter, calculation processing 1). The second is to calculate a difference between the integrated value of the power consumption of one day (the current day) and the planned power consumption of the corresponding day among the planned power consumption (hereinafter, calculation processing 2).
). Third, a difference between the power consumption accumulated daily in the current month and the integrated value of the power consumption to be consumed up to that day in the current month is calculated (hereinafter referred to as calculation process 3). These calculation results are stored in the customer database of the corresponding power consumer as power history at any time.

The management device 12 is provided with the power measuring device 11
Switch buttons 51a, 53 displayed on the display panel 50
is operated by the power consumer, a calculation result corresponding to the operation is transmitted to the power measuring device 11, and the display unit 11
a is displayed on the display panel 50. That is, on the initial screen, the calculation result of the above calculation processing 1 is displayed in the numerical value comparison display window 5.
1, and the result of the calculation process 2 is displayed in the transition graph display window 53 (the display state shown in FIG. 3). Then, when the power consumer presses the switching button 51a once from this display state, the result of the calculation process 2 is displayed in the numerical value comparison display window 51 (indicated by reference numeral 511).
From this display state, the power consumer switches the switch button 51a.
Is pressed once, the result of the calculation process 3 is displayed in the numerical value comparison display window 51 (indicated by reference numeral 512). Further, from the initial screen display state, the power
When the user presses 3a once, the result of the calculation process 3 is displayed on the transition graph display window 53 (indicated by reference numeral 531). In addition, from this display state, the power consumer operates the switch button 5.
When the user presses 3a once, the information (indicated by reference numeral 532) on the financial product purchased by the user is displayed in the transition graph display window 53 as described above.

The power consumer checks the power information displayed on the display panel 50 at any time, and works to save energy with high awareness.

Then, for example, when one month has elapsed, as shown in FIG. 2, the management device 12 compares the measured power consumption C1 actually used in this month with the actual power consumption actually consumed in the same month in the past. A difference D (A1-C1) from A1 is calculated, and based on the electricity rate corresponding to the calculated electric energy of the difference D,
Purchasing financial products of a predetermined amount on behalf of electricity consumers.
For example, if the electricity rate of the difference D for the month is 1,000 yen, the financial product for the 1000 yen is purchased.

That is, the management device 12 communicates with the terminal device 15 of the financial product handling company on behalf of the electric power consumer.
A process related to a purchase procedure of a financial product for 000 yen is executed. In addition, when the management device 12 executes a process related to a purchase procedure with the terminal device 15, the management device 12 requests a transfer to the server device 13 of the financial institution with which the power consumer has contracted. The financial institution that has received the transfer request debits 1000 yen from the personal account of the corresponding power consumer provided in the server device 13 and is provided in the server device 14 of the financial institution with which the financial product handling company has contracted. Transfer processing to the account of the relevant financial instruments trading company. The transfer fee is not considered here.

After confirming that the purchase fund has been transferred to the account, the financial product handling company purchases the financial product for the amount of the deposit on behalf of the electric power consumer, and then checks the asset status of the financial product purchased by the current month ( The increase / decrease) is reported to the power consumer. As a method of contacting, a notice by mail or a notice by facsimile can be used. In addition, the terminal device 15
Transmits the asset status information to the power measuring device 11 in the power consumer's home, and notifies the power measuring device 11 by displaying the asset status in the transition graph display window 532 provided on the display panel 50 of the display unit 11a of the power measuring device 11. You may do so. Further, when the power consumer has a personal computer or a mobile phone, the power consumer may be notified by e-mail. In any case, the communication method is based on a contract between the power consumer and the financial product handling company.

Regarding which financial product is to be purchased, for example, various financial products such as securities, investment trusts, insurances, and banks are lined up in advance, and power consumption is selected from among the lined up financial products. May be determined in advance between the consumer and the financial product handling company or between the power consumer and the management company of the management device 12 requested by the financial product handling company. For example, by purchasing a so-called eco-fund for companies actively working on environmental issues, it becomes possible to build a more global energy saving promotion system in which individuals and companies are integrated.

As a result, the power consumer can work more aggressively on energy saving because the financial products to be his / her assets increase by the amount of power saved. Ona
The predetermined amount does not necessarily have to be the same as the difference in electricity rate. For example, the ratio can be determined by an initial contract, such as purchasing a financial product at an amount 5 or 10 times the difference. is there.

As shown in FIG. 2, for example, as shown in FIG. 2, the operating cost for operating the management device 12 is the measured power consumption C1 actually used in this month and the actual power consumption actually used in the same month in the past. The difference D from the used electric energy A1 is calculated, and an amount (30 yen) obtained by multiplying an electric charge (1000 yen) corresponding to the calculated electric energy of the difference D by a certain ratio (for example, 3%) is set as a fee. This can be deducted and applied to operating costs. Alternatively, instead of being collected from the electric power consumer, a fixed amount (or 1,000 yen) corresponding to the amount of electric power of the difference D per month (or a certain amount ( For example, it is also possible to collect an amount multiplied by 3% or the like) and to use this as an operation cost.

Further, in the power saving promotion system of the present embodiment, it is possible to construct a system so that the power usage status of another power consumer home 1 can be browsed through the Internet N1. In this case, from the viewpoint of private protection, only the power usage status of the power consumer who has accepted the posting is displayed via the Internet. This allows the power consumer to work on his or her own energy saving while referring to the power usage status of other power consumers who live in a house having a similar family structure and similar specifications.

In the above embodiment, the power measuring device 1
1 is described as a configuration having only a function of measuring power and a function of displaying various types of power information and financial product information. For example, means for determining a planned power consumption B serving as a benchmark, A power calculating device 11 compares the expected power consumption B and the actually consumed power C with a calculating means.
It is also possible to have it on the side. By providing such a determination unit and a comparison operation unit on the power measurement device 11 side, the load on the management device 12 side that manages many power measurement devices 11 is reduced.
