[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an energy usage reduction evaluation method, system and apparatus for evaluating the degree of energy usage reduction, a program for causing a computer to evaluate the degree of energy usage reduction, and a recording medium on which the program is recorded.
[0002]
[Prior art]
Energy saving is important from the viewpoints of both environmental conservation and economic efficiency. Efforts such as turning off the light frequently and lowering the set value of the heating temperature are being made. As a device that supports energy saving efforts, a device that displays a current energy consumption amount is used. This apparatus is configured to attach a power measuring device to a distribution board, for example, and display the measured power on a display.
[0003]
On the display, for example, the accumulated power consumption obtained by accumulating the measured power can be displayed every other minute. By increasing the displayed cumulative power consumption, it is possible to increase the power saving awareness of those who have seen the display.
[0004]
Further, the device sets a target value of power consumption of the current year based on, for example, power consumption of the previous year, and when the measured value of the power meter reaches the target value, a sound or a message is displayed from the display unit. It can also be output. By setting the target value, interest in the current power consumption is increased, and power saving awareness can be further enhanced.
[0005]
In addition, the amount of energy used grasped by a billing slip or the like is transmitted to a website established on the Internet, and a target value of power consumption for the current year is obtained based on the power consumption of the previous year. By setting the target value, interest in the current power consumption is increased, and power saving awareness can be further enhanced.
[0006]
[Problems to be solved by the invention]
In the apparatus and method described above, setting of a target value or an energy saving approach is evaluated based on the energy consumption amount of the previous year. For example, as shown in FIG. 8, when the energy usage E1 of the month M1 decreases to the energy usage E2 in the month M2 one year later, the ratio of A (= E1-E2) to B (= E1) Evaluation is performed based on (A / B).
[0007]
However, since it is based on its own past performance, it is difficult to set a target value or an evaluation standard for efforts to save energy, and there is a possibility that appropriate evaluation has not been performed. For example, when the amount of energy used is significantly higher than the average value, it is considered that a significant reduction can be easily performed. Conversely, if the energy usage is below the average value, a small reduction is considered difficult. Furthermore, a relatively large reduction in energy consumption is possible in the first year, but it is considered that the reduction will gradually become difficult after the second year.
[0008]
In addition, it is considered that the difficulty in reducing energy consumption varies depending on attributes such as family structure, house structure, or floor area. It is difficult to set a target value without considering such attributes or to appropriately evaluate energy saving efforts.
[0009]
The present invention has been made in view of such circumstances, and accepts an energy usage amount and an attribute of a measurement unit body in which the energy usage amount is measured, and sets a reference usage amount to be used as an evaluation criterion for each attribute. To provide an energy usage reduction evaluation method, an energy usage reduction evaluation system, an energy usage reduction evaluation device, a computer program, and a recording medium that can set a reference usage amount according to the attribute of each customer as a target value. With the goal.
[0010]
In addition, the present invention accepts the energy usage and attributes to be evaluated, and evaluates the degree of reduction in energy usage with respect to the reference usage of the accepted attribute, thereby reducing the degree of energy usage reduction based on customer attributes. It is an object to provide an energy usage reduction evaluation method, an energy usage reduction evaluation system, an energy usage reduction evaluation device, a computer program, and a recording medium that can be evaluated.

In addition, the present invention provides an energy usage reduction evaluation system that can provide the terminal device with the most suitable reference usage amount by means of transmitting the reference usage amount corresponding to the attribute received from the terminal device to the terminal device. The purpose is to provide.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
FIG. 1 shows a configuration example of an energy usage reduction evaluation system provided with an energy usage reduction evaluation device according to the present invention. In FIG. 1, a management server (energy usage reduction evaluation device) 10 and a customer terminal (terminal device) 30 are connected to a communication network 20 such as the Internet.
[0028]
The management server 10 includes a communication unit 15 that controls communication with the communication network 20, an input unit 16 such as a mouse and a keyboard, an output unit 17 such as a monitor and a printer, and a RAM (Random Access Memory) 14 such as a DRAM. A hard disk 13, an external storage means 12 such as a flexible disk drive or a CD-ROM drive, and a CPU (Central Processing Unit) 11.
[0029]
The CPU 11 controls the above-described units 12 to 17 of the management server 10. Further, the CPU 11 temporarily stores the program or data received from the input unit 16 or the communication unit 15, the program or data read from the external storage unit 12 or the hard disk 13 in the RAM 14, and executes the program or data stored in the RAM 14. Various processes such as computation are performed, and various processing results or temporary data used for various processes are stored in the RAM 14. Data such as calculation results stored in the RAM 14 is stored in the hard disk 13 or output from the output means 17 or the communication means 15 by the CPU 11.
[0030]
The communication means 15 operates as means for receiving the energy usage and the attributes of the customer (measurement unit) from which the energy usage is measured. The received energy usage and attributes are stored in the hard disk 13 by the CPU 11. The CPU 11 operates as means (setting means) for setting a reference usage amount used as an evaluation criterion for each attribute based on the received energy usage amount and attribute.
[0031]
For example, the CPU 11 obtains the minimum energy usage for each attribute, and sets the obtained minimum energy usage as the reference usage. Alternatively, when the energy usage amounts are arranged in ascending order, the energy usage amount of the rank corresponding to, for example, a rank number of 5% is set as the reference usage amount from the smallest. Here, the rank number of 5% from the smallest means the rank number corresponding to 5% of the total number of customers when the customers included in the attribute are arranged in the order of small usage. For example, when there are 200 customers included in the attribute, the tenth smallest usage amount is set as the reference amount. The set reference usage amount is stored in the hard disk 13 by the CPU 11.
[0032]
The communication means 15 operates as means for receiving from the customer terminal 30 the energy usage to be evaluated and the attributes of the customer (measurement unit) whose energy usage is measured. The accepted attributes are stored in the RAM 14 or the hard disk 13 by the CPU 11. The CPU 11 operates as means (selection means) for selecting a reference usage amount corresponding to the accepted attribute from the set reference usage amounts, and reads the selected reference usage amount from the hard disk 13 to the RAM 14.
[0033]
The communication unit 15 operates as a unit (transmission unit) that transmits the selected reference usage amount to the customer terminal 30 that has received the attribute. The reference usage amount read into the RAM 14 is transmitted from the communication means 15 to the customer terminal 30 by the CPU 11. The reference usage amount transmitted to the customer terminal 30 is used as a target value for energy usage.
[0034]
The CPU 11 calculates a reduction amount (reduction amount calculation means) of the received energy usage amount for a predetermined period, and calculates a difference (difference) between the first or last energy usage amount of the predetermined period and the selected reference usage amount. Calculation means), and operates as means (ratio calculation means) for calculating the ratio of the calculated reduction amount to the calculated difference. The CPU 11 reads, for example, the energy usage amounts for the current fiscal year and the previous fiscal year from the energy usage amounts to be evaluated stored in the RAM 14, calculates the reduction amount, and stores them in the RAM 14. Here, when the reduction amount becomes negative, it indicates that the energy consumption amount has increased from the previous year. Further, the CPU 11 reads the reference usage amount of the previous year from the hard disk 13 to the RAM 14, obtains the difference between the read energy usage amount and the reference usage amount of the previous year, and stores it in the RAM 14. The CPU 11 calculates the ratio of the reduction amount to the difference stored in the RAM 14 and stores it in the RAM 14.
[0035]
The CPU 11 evaluates the degree of energy consumption reduction according to the obtained ratio, and transmits the evaluation result from the communication means 15 to the customer terminal 30. A higher ratio gives a higher rating.
[0036]
The computer program recorded on a recording medium such as a CD-ROM is read by the external storage means 12, stored in the hard disk 13, and executed by the CPU 11, whereby the CPU 11 can be operated as each means described above. Using the communication unit 15, a computer program can be received from another device connected to the communication network 20 and stored in the hard disk 13.
[0037]
The customer terminal 30 includes a communication unit 38 that controls communication with the communication network 20, an input unit 32 such as a button-type switch, an output unit 34 such as a display panel, and a storage unit 36 such as a ROM, a RAM, and a flash memory. And a control unit 40 that performs calculation and control of the above-described units 32, 34, 36, and 38.
[0038]
The control unit 40 stores the data received from the input unit 32 or the communication unit 38 in the storage unit 36, performs various processes such as execution of a program stored in the storage unit 36 or calculation of data, and outputs various processing results. Store in the storage unit 36. Data such as calculation results stored in the storage unit 36 is output from the output unit 34 or the communication unit 38 by the control unit 40.
[0039]
The storage unit 36 stores an attribute of a customer, which is a measurement unit for measuring energy usage. The attribute is input from the input unit 32. Attributes include information on residents such as singles, couples, elderly couples, couples and children, elderly people living together, etc., and the family structure and the number of family members, etc. And information about the area such as an address.
[0040]
As the customer terminal 30, a computer can be used in addition to the same device as the conventional one. For example, when using a computer including the CPU 11, the external storage unit 12, the hard disk 13, the RAM 14, the communication unit 15, the input unit 16, the output unit 17 and the like shown in FIG. 1, the computer recorded on a recording medium such as a CD-ROM The program can be stored in the hard disk 13 from the external storage means 12 and can be executed by the CPU 11.
[0041]
In this case, the control unit 40, the input unit 32, the output unit 34, the storage unit 36, and the communication unit 38 substantially correspond to the CPU 11, the input unit 16, the output unit 17, the RAM 14, the hard disk 13, and the communication unit 15, respectively.
[0042]
The energy usage amount may be measured by a measuring instrument. For example, as shown in FIG. 2A, a measuring instrument that measures the energy usage amount and transmits the measured energy usage amount and attribute to the management server 10. When 26 is provided at the customer's home, the energy usage and attributes measured by the measuring instrument 26 are transmitted to the management server 10. Generally, the energy usage accumulated for one month is transmitted.
[0043]
Further, the energy usage amount may be measured by the meter reader. For example, as shown in FIG. 2B, the meter meter or the like inputs the energy usage amount, and the input energy usage amount and attribute are managed by the management server. 10, the energy usage amount and the attribute input to the mobile terminal 28 are transmitted to the management server 10. Generally, the energy usage accumulated for one month is transmitted.
[0044]
The attribute includes the customer identification number. For example, only the customer identification number among the attributes is stored in the customer terminal 30, the portable terminal 28 or the measuring instrument 26, and the other is stored in the hard disk 13 of the management server 10. You can also. Customers can be classified according to attributes.
[0045]
The energy usage of each attribute is sent to the management server 10 from the measuring instrument 26 and the portable terminal 28 shown in FIGS. 2A and 2B, and the management server 10 accepts the energy usage of each attribute. Specifically, the energy usage amount and attribute sent from the measuring instrument 26 or the portable terminal 28 are received by the communication means 15 and stored in the hard disk 13.
[0046]
When the energy usage amount is sent to the management server 10 by the measuring device 26 or the portable terminal 28 shown in FIG. 2A or 2B, it is not necessary to input the energy usage amount used for diagnosis. The CPU 11 can read out the energy usage corresponding to the identification number included in the accepted attribute from the hard disk 13 and perform diagnosis. When the energy usage is not stored in the management server 10, the energy usage is input and transmitted from the input unit 32 of the customer terminal 30.
[0047]
Next, the evaluation of the degree of energy consumption reduction using the energy usage reduction evaluation system according to the present invention will be described.
[0048]
An example of a procedure for setting a reference usage amount (hereinafter referred to as a reference amount) is shown in FIG. The energy usage (hereinafter referred to as usage) is input or measured by the input unit 32 of the customer terminal 30, the portable terminal 28 or the measuring device 26 (S10). The control unit 40, the portable terminal 28, or the measuring device 26 of the customer terminal 30 transmits the input amount measured or measured and the attribute stored in advance to the management server 10 (S12). The attribute is stored in advance in the storage unit 36 of the customer terminal 30, the portable terminal 28, or the memory (not shown) of the measuring instrument 26.
[0049]
The communication unit 15 of the management server 10 receives the transmitted usage amount and attribute (S14). The received usage amount is stored in the hard disk 13 by the CPU 11 (S16). The attribute includes, for example, an identification number for each customer, and the usage amount is stored for each customer. Usage amounts sent from a large number of customers not shown in FIG. 1 and FIGS. 2A and 2B are also stored in the hard disk 13 in the same manner.
[0050]
The CPU 11 sets a reference amount (reference usage amount) for each attribute (S18). For example, the usage amount can be classified according to the attribute, the minimum usage amount can be obtained for each attribute, and the minimum usage amount can be set as the reference amount. As will be described later, the reference amount can be used as a target value for reducing the amount of energy used. In this case, the minimum consumption actually realized becomes the target value.
[0051]
Alternatively, the usage amount close to the minimum value can be set as the reference amount. For example, the usage amount of the rank number of 5% from the smallest can be set as the reference amount. The minimum usage amount may be a unique value, for example, when there was a day when you were away on a trip, etc., so by selecting the usage amount of the rank number of 5% from the smallest one, a unique value Can be excluded.
[0052]
The set reference amount (reference use amount) is stored in the hard disk 13 by the CPU 11 (S20). The reference amount can be set on a monthly basis, for example, in accordance with the measurement of the usage amount. The reference amount is stored in the hard disk 13 on a monthly basis in the same manner as the usage amount.
[0053]
The reference amount can be a target value for reducing the amount used. An example of the target value display procedure is shown in FIG. The input unit 32 of the customer terminal 30 is operated to transmit the attribute and target value transmission request stored in advance in the storage unit 36 to the management server 10 (S42).
[0054]
The management server 10 receives the attribute and target value transmission request through the communication unit 15 (S44). The CPU 11 detects the reception of the target value transmission request, reads the reference amount (reference usage amount) corresponding to the received attribute from the hard disk 13 (S46), and transmits it from the communication means 15 (S48).
[0055]
The transmitted reference amount is received by the communication unit 38 of the customer terminal 30 (S50). The received reference amount is sent to the output unit 34 and displayed by the control unit 40 (S52). The customer works on energy saving by setting the reference amount displayed on the output unit 34 of the customer terminal 30 as a target value.
[0056]
Next, FIG. 5 shows an example of the procedure for evaluating the degree of use reduction. In this description, a case where the usage amount is not stored in the management server 10 will be described as an example. The evaluation applicant operates the input unit 32 of the customer terminal 30 and inputs the usage amount (S60). After the usage amount is input, the control unit 40 transmits the usage amount and attributes stored in the storage unit 36 to the management server 10 (S62).
[0057]
The transmitted usage amount and attribute are received by the communication means 15 of the management server 10 (S64). The received usage amount and attribute are stored in the RAM 14 by the CPU 11, and a reference amount (reference usage amount) corresponding to the received attribute is read from the hard disk 13 to the RAM 14 (S66). The CPU 11 performs evaluation based on the received usage amount and the read reference amount (S68). In the evaluation, the reduction amount of the received usage amount with respect to the previous year is compared with the difference between the usage amount of the previous year and the read reference amount.
[0058]
An example of the comparison between the reduction amount and the difference is shown in FIG. In FIG. 6, M1 and M2 are the same month in the previous year and this year, E1 is the amount used in the previous year, E2 is the amount used in the current year, and E3 is the reference amount set based on the amount used in the previous year. It is. Further, A (= E1-E2) is a reduction in the usage amount relative to the previous year, and C = (E1-E3) is a difference between the usage amount and the reference amount in the previous year.
[0059]
CPU11 calculates | requires A, C, and A / C, and performs evaluation based on the calculated | required ratio. The higher the ratio, the higher the rating. For example, the ratio is a negative number (when the usage is increased), 0 to 0.20, 0.21 to 0.40, 0.41 to 0.60, 0.61 to 0.80, 0 The evaluation can be performed in seven stages of .81 to 1.00 and 1.01 or more. The evaluation result is transmitted from the management server 10 to the customer terminal 30 (S70).
[0060]
The transmitted evaluation result is received by the communication unit 38 of the customer terminal 30 (S72), sent to the output unit 34 by the control unit 40, and the evaluation result is displayed (S74). Customers can improve their motivation for future energy-saving efforts by receiving evaluations for energy-saving efforts. For example, ranking can be performed according to the calculated ratio. Since the ratio is calculated based on a reference amount corresponding to the attribute, ranking can be performed for each attribute or for all attributes.
[0061]
In the above-described embodiment, the reference amount is set to a usage amount of 5% from the smallest, but the reference amount is not limited to 5%, and can be set to 10%, for example. Alternatively, an average value of usage amounts of customers classified into the same attribute can be set as the reference amount.
[0062]
For example, when the average value of usage is set to the first reference amount, the usage amount of 5% of ranks from the smallest is set to the second reference amount, and the usage amount to be evaluated is larger than the first reference amount The first reference amount can be set as a target value, and if it is smaller than the first reference amount, the second reference amount can be set as the target value. If the amount used exceeds the average value, the difference from the reference amount that is close to the minimum (5% from the smallest) is large, making it an unrealistic target and willingness to save energy May disappear. However, when the reference amount close to the average value is set, it becomes a realistic target, and the motivation for energy saving can be increased.
[0063]
In FIG. 6, the ratio (A / C) is calculated using the reference amount E3 at the start of the period (M1). However, as shown in FIG. 7, the reference amount E4 at the end of the period (M2) is used. The ratio (A / D) can also be calculated. The reference amount varies from year to year even in the same month. In FIG. 7, the current reference amount can be used for evaluation.
[0064]
Further, for example, it is possible to transmit the usage amount of electricity from the measuring instrument 26 and transmit the usage amount of water and gas from the customer terminal 30. In this case, evaluation can be performed separately for electricity, gas, and water, or electricity, gas, and water can be evaluated together.
[0065]
In FIG. 1, the usage amount and attribute reception, the reference amount setting, and the reduction degree evaluation are performed by one apparatus (management server 10). It is also possible to set the amount with another device and acquire the reference amount according to the attribute from the other device. Alternatively, the reference amount corresponding to the attribute can be received from the management server 10 and the reduction evaluation can be performed at the customer terminal 30. In this case, only the attribute is sent from the customer terminal 30 to the management server 10.
[0066]
【The invention's effect】
According to the first, third, sixth, ninth, and tenth inventions, it is most suitable for the measurement unit body by setting a reference usage amount to be used as an evaluation criterion for each attribute based on the received energy usage amount and attribute.
