The present invention relates to a method and device for managing energy consumption and, more particularly, to a method and device for managing energy consumption for each time period to assist a user in achieving a target energy consumption charge for a specific period.
The Internet is evolving from a human-centric network, in which humans generate and consume information, into an Internet of things (IoT) network in which distributed things exchange and process information. Further, the IoT technology combines with big data processing technology through connection with a cloud server or the like, thus developing into Internet of everything (IoE) technology. In order to realize the IoT, relevant technologies such as sensing technology, wired/wireless communication and network infrastructure, service interface technology, and security technology are being required. Thus, technologies such as a sensor network, machine-to-machine (M2M), and machine type communication (MTC) are now being studied.
In the IoT environment, an intelligent Internet technology (IT) service can be provided that collects and analyzes data generated from connected things and thereby creates new value in a human life. The IoT technology can be applied to fields of smart home, smart building, smart city, smart car or connected car, smart grid, health care, smart home appliance, and advanced medical service through the fusion of existing information technology (IT) and various industries.
Meanwhile, a typical method for managing energy consumption of energy consuming devices in a user's house is to compare monthly charges with each other. In other words, since the user merely uses fragmentary information such as already charged rates, the user has difficulty in managing the energy effectively. Therefore, there is a need of a method for managing energy consumption by subdivided periods, based on energy consumption related information that reflects the characteristics of the user, and on a user's target charge for a certain period.

For reference, the term “energy usage status information” in the present invention refers to information related to energy usage, charges, and the like at the present time that the user can use to manage energy consumption.
In the present invention, the term “target charge information” refers to information on an energy charge that the user inputs through a terminal based on desired consumption of a certain period.
In the present invention, the term “energy charge budget information” refers to information on energy charges distributed in each period to comply with the target charge information.
The system for managing energy consumption may include a user terminal 100, a server 110, a gateway 120 connected to the server 110 in one or more households, and one or more electricity consuming devices 120 in the household.
The user terminal 100 may include a mobile communication terminal used generally in the technical field of the present invention. The user terminal 100 may be connected to the server 110 to transmit and receive information necessary for managing energy consumption. Although not shown in
According to an embodiment of the present invention, the user terminal 100 may generate “energy usage status information” necessary for managing energy consumption. The energy usage status information is information related to energy usage at the present time that the user can use to manage energy consumption. The energy may include at least one of electricity, water, and gas, but the following description will be limited to a case of electricity for simplicity of explanation. However, it is apparent to those skilled in the art that the present invention can be applied to energy, such as water, gas, etc. in addition to electricity, which incurs a burden of charges in a building. Specifically, the energy usage status information necessary for managing energy consumption may be generated by an application installed in the user terminal 100.
The energy usage status information may include at least one of energy charge budget information, energy charge information at the present time, saving charge information at the present time against charge information at a predetermined past time point, ranking information with a friend or similar group based on saving charge information, and carbon emission reduction information based on reduced usage information.
The user terminal 100 may receive, from a user, target charge information per period to manage energy consumption. The “target charge information” may be input from the user through a display, and corresponds to a target electricity charge that the user desires to consume for a certain period of time. The user terminal 100 may display a user interface (UI) for receiving the target charge information per period on the display. The period may include, for example, one month. Also, the user terminal 100 may check the energy usage status information and display it on the display.
The user terminal 100 may provide the user with a user experience (UX) of managing energy consumption by expressing the energy usage status information through the UI. That is, the present invention may deal with feelings, attitudes, behaviors, etc. of the user who manages energy consumption.
The server 110 may be connected to the gateway 120 in each household and receive energy consumption information of the energy consuming device 125. Alternatively, the server 110 may be connected to a server of an energy supplier and obtain information on energy consumption. The server 110 may accumulatively store such energy consumption information and generate energy consumption history information. The server 110 may provide the received energy consumption information to the user terminal 100. Also, the server 110 may generate the energy usage status information based on the received energy consumption information. That is, the energy usage status information may be selectively generated by an application in the user terminal 100 or in the server 110.
Additionally, the server 110 may store and manage the received energy consumption information in units of hour, day, and month. Also, using the received energy consumption information, the server 110 may provide a real-time prediction and management service in units of hour, day, and month. Further, the server 110 may receive energy usage information of households in a certain area as well as energy usage information of a household having the user of the user terminal 100, and then apply a game model through comparative monitoring for energy usage charges. The game model through the comparative monitoring may be based on, for example, a target charge, set by the user, or a saving charge against a past time point.
In addition, the server 110 may determine a household for the comparative monitoring to be compatible with the user of the user terminal 100. That is, rather than performing the comparative monitoring for households in a certain zone determined by a postal code, etc., the server may perform the comparative monitoring for households grouped in accordance with ages of household members, sizes of residences, applied rate systems, etc. in order to increase the association with the user. This grouping causes the comparison of realistic and meaningful energy charges and has the effect of motivating the user to manage energy consumption.
The gateway 120 may collect information on the energy consumption of the energy consuming devices existing in a house and transmit the collected information to the server 110. The gateway 120 may communicate with the energy consuming device 125 having a communication module built therein and collect information on energy consumption. On the other hand, the legacy energy consuming device 125 having no built-in communication module may measure information on energy consumption and transmit the measured information to the gateway 120 through a smart meter having a built-in communication module.
The energy consuming devices 125 may include all energy consuming devices existing in a house or a building. Assuming that the energy is electric electricity, the energy consuming devices may include a TV, a desktop computer, a refrigerator, a lamp, and the like. The energy consuming device 125 having the communication module embedded therein may transmit energy consumption information to the gateway 120. The legacy energy consuming device 125 having no built-in communication module may measure information on energy consumption, be connected to a smart meter having a built-in communication module, and then transmit the measured information to the gateway 120.
Hereinafter, it is assumed that the energy is electricity. Specifically,
Referring to
Thereafter, when the server 205 receives a message for requesting electricity usage status information from the terminal 210 at step S230, the server 205 may generate the electricity usage status information at step S240. The electricity usage status information may include at least one of electricity charge budget information, electricity charge information at the present time, saving charge information at the present time against charge information at a predetermined past time point, ranking information with other user group based on saving charge information, and carbon emission reduction information based on reduced usage information. At step S250, the server 205 may transmit the generated electricity usage status information to the terminal 210.
Then, at step S260, the terminal 210 may display the received electricity usage status information on the display. Displaying the electricity usage status information on the display by the terminal will be described later in detail with reference to
Referring to
Thereafter, at step S280, the terminal 210 may transmit a message for requesting electricity usage status information to the server 205. Then, the server 205 that receives the message may transmit, to the terminal 210, the electricity usage information received from the gateway 200. Then, at step S290, the terminal 210 that receives the electricity usage information may generate electricity usage status information. The electricity usage status information is the same as that generated by the server 205 of
Specifically,
At step S315, the server or terminal may calculate an electricity charge budget per period based on a user's target charge. The server or terminal may predict an electricity charge for each period based on electricity consumption history information of the electricity consuming device received from the gateway, and then calculate the electricity charge budget per period to meet the target charge entered by the user. Rather than deriving a linear electricity charge budget per period in accordance with the target charge entered by the user, the server or terminal may derive a suitable electricity charge budget per period by considering a user's electricity usage pattern or the like included in the electricity consumption history information. A detailed description thereof will be described later in
At step S320, the server or terminal may generate comparative information between a current electricity charge and the electricity charge budget per period. By comparing a current cumulative electricity charge with an electricity charge budget at the present time in the electricity charge budget information per period, the server or terminal may generate information on target achievement probability based on a comparison ratio. The target achievement probability may be indicated as a grade according to a predetermined ratio. The grade may include, for example, excellent, good, fair, need of saving, and the like.
In addition, at step S330, the server or terminal may generate a similar group from households within a certain area. The “similar group” refers to groups being similar to the user in consideration of the characteristics of each household. The characteristics considered when generating the similar group may include at least one of the age of members constituting a household, the size of a building, and a rate system being used. Based on information received from the gateway, the server or terminal may check information on the characteristics of each household. A more detailed description thereof will be described later with reference to
Thereafter, at step S335, the server or terminal may generate user ranking information in the generated similar group or a neighbor group, based on a current saving charge against a target charge or a past electricity charge. The “neighbor group” refers to households within a certain distance from a building where the user is located. In addition, when there is a user input for a specific object for which the comparative monitoring is desired, the server or terminal may generate the user ranking information in consideration of this input. A group of specific objects for which the comparative monitoring is desired is defined as a “friend group”. Also, at step S340, the server or terminal may generate carbon emission information based on saving usage information against an electricity charge at a certain time point in the past. The carbon emission information may be calculated by a predetermined equation, and is not described in detail as being not directly related to the present invention.
At step S350, the server or terminal generates electricity usage status information by integrating the above generated information. Specifically, the electricity usage status information may include at least one of electricity charge budget information, electricity charge information at the present time, saving charge information at the present time against charge information at a predetermined past time point, ranking information with other user group based on saving charge information, and carbon emission reduction information based on reduced usage information.
Specifically, this diagram shows that the server or terminal simplifies the electricity usage history information necessary for predicting the electricity charge to generate the electricity charge budget information at step S315 of
The server may receive information on electricity usage per household from the gateway. Also, the server may collect the electricity usage information and generate electricity usage history information. The electricity usage history information may include electricity usage information of one household with respect to each day of the week, each week, and each hour. The electricity usage history information may be represented by a matrix ( ) in which the T-axis is a day of the week, the j-axis is a week, and the k-axis is an hour. For example, in case of electricity usage history information having electricity usage information for three weeks, a matrix 400 of 7 (days)*3 (weeks)*24 (hours) may be generated.
In case of using the first simplification method, the server may simplify the 7*3*24 matrix 400 into a 2*1*1 matrix 410. That is, information for three weeks is integrated according to weekday and weekend, and an average of information for 24 hours is calculated. In the end, simplified one-week electricity usage information according to weekday and weekend is obtained.
In case of using the second simplification method, the server 36 may simplify the 7*3*24 matrix 400 into a 2*1*24 matrix 420. That is, information for three weeks is integrated according to weekday, weekend, and hour. In the end, simplified one-week electricity usage information according to weekday, weekend, and hour is obtained. In case of using the third simplification method, the server may simplify the 7*3*24 matrix 400 into a 7*1*24 matrix 430. In this case, information for three weeks is integrated according to day of the week and hour, and simplified one-week electricity usage history information is obtained.
When integrating and simplifying information for three weeks as described above, a weight may be assigned to each week. The weight of electricity usage information for the last one week is (%), the weight of electricity usage information for one week before the last one week is (%), and the weight of electricity usage information for one week before the last two weeks is (%). The weights may be initially predetermined as a specific value and then changed respectively while the sum of the three weights maintains 100%.
The server or terminal may change the weights, based on a variation of electricity usage accumulated over time. That is, if variations of electricity usage for the last one week and for one week before the last week are large after one week has elapsed after the prediction of electricity usage, it may be seen that the recent electricity usage information has a greater influence. Therefore, a greater weight may be given to the recent electricity usage information. The above variation may be derived from the electricity usage for the last one week and for one week before the last week.
The simplifying method shown in
At step S500, the server or terminal may receive electricity usage information for a certain period. In this case, the server may receive electricity consumption information from a gateway installed in each household. In addition, the server may receive electricity usage information from a smart meter installed in each household. The server that receives the electricity usage information may transmit the received electricity usage information to the terminal.
Thereafter, at step S510, the server or terminal determines whether the user uses a variable rate system. This is to select a method for simplifying the electricity usage history information described in
If it is determined at step S510 that the user does not use the variable rate system, the server or terminal selects the second simplification method at step S520. That is, the server or terminal may simplify, for example, the 7*3*24 matrix 400 to the 2*1*24 matrix 420 as described above with respect to the received electricity usage information for three weeks. That is, information for three weeks is integrated according to weekday, weekend, and hour, and then the simplified one-week electricity usage information according to weekday, weekend, and hour is obtained. When the user uses the variable rate system, the server or terminal selects the third simplification method at step S530. That is, the server may simplify, for example, the electricity usage history information of 7 (days of week)*3 (weeks)*24 (hours) to the 7*1*24 matrix 430 with respect to the received electricity usage information for three weeks. In this case, information for three weeks is integrated according to days and hours, and then the simplified one-week electricity usage history information is obtained. When integrating the three-week information, the above-described weight for each week may be considered.
Thereafter, at step S540, the server or terminal may predict electricity usage information in units of hour, date, day of week, and month after the present time by using the simplified electricity usage history information.
Thereafter, at step S550, the server or terminal may convert the predicted electricity usage information into an electricity charge and thereby predict an electricity charge in units of hour, date, day of week, and month. Based on this information on the electricity charge per period, a pattern of the electricity charge may be predicted.
When the predicted electricity usage information is converted into the electricity charge, the server or terminal may consider the rate of change in charges with respect to the temperature change and thus further consider information about surrounding environment. The server or terminal may receive temperature information at a time point to be predicted from an external server such as a weather station server.
Thereafter, at step S560, the server or terminal may generate electricity charge budget information by converting the predicted electricity charge into a budget based on a target charge received from the user. For example, if the user inputs a one-month target charge, the predicted one-month electricity charge may be adjusted based on the target charge. Let's suppose that the total one-month electricity charge according to the one-month electricity charge pattern predicted by the server or terminal at step S550 exceeds a one-month target charge inputted by the user. In this case, the electricity charge budget information per period may be generated by reducing the total electricity charge for one month to the target charge and also reducing the electricity charge per hour, date, day of week, and month determined according to the predicted one-month electricity charge pattern at the same rate.
Likewise, if the monthly electricity charge according to the predicted one-month electricity charge pattern is less than the target charge, the electricity charge budget information per period may be generated by increasing the total electricity charge for one month to the target charge and also increasing the electricity charge per hour, date, day of week, and month determined according to the predicted one-month electricity charge pattern at the same rate.
As described above, by calculating the electricity charge budget for each period using the electricity usage history information, rather than deriving the electricity charge budget linearly according to hour or date, it is possible to form a budget to further comply with a user's electricity usage pattern and thereby efficiently manage energy consumption. The above-described operation in
Specifically,
The terminal may display a rate start date 600 from which a charge is to be measured, and also display a target period 605 for which a target charge is to be applied. In addition, the terminal may display, in the middle of the screen, a bar-shaped item 606 for indicating a charge and another bar-shaped item 607 for indicating the amount of carbon emission. In addition, the terminal may display an item 610 for indicating the last month usage charge of a similar group, an item 615 for indicating the last month usage charge of a neighbor group, and an item 617 for indicating the last month usage charge of the user. These items 610, 615, and 617 may be in the form of a line perpendicular to the item 606 for indicating the charge. The items 610, 615, and 617 may be overlapped with the item 606 for the charge at positions determined based on information represented by the items. When usage charges of a similar group and a neighbor group and the user's last month usage charge are provided, the user may refer to this when setting the target charge.
The terminal may display an item 630 for receiving the target charge from the user. The item 630 for receiving the target charge may be displayed to be overlapped with both the bar-shaped item 606 for indicating the charge and the bar-shaped item 607 for indicating the carbon emission amount. In addition, the item 630 for receiving the target charge may have a circular form with arrows on both sides, so that the user can input the target charge by moving the item 630 from side to side. When the terminal detects a left or right movement of the item 607 for receiving the target charge, the terminal may determine, based on a moving distance, the target charge information inputted by the user. Also, since the target charge is changed in position according to an input, the user may compare, based on a relative position, the target charge with the item 610 for indicating the last month usage charge of the similar group, the item 615 for indicating the last month usage charge of the neighbor group, or the item 617 for indicating the last month usage charge of the user. That is, based on such a relative distance between the item 607 for receiving the target charge and the item 610, 615, or 617, the terminal may determine the user's target charge information.
In addition, although not shown in the drawing, the user not only inputs the target charge by moving the item 607 for receiving the target charge from side to side, but also may directly input the target charge by using a keypad which is displayed when the item 607 is touched.
Depending on the relative position of the item 620 for receiving the target charge, the bar-shaped item 606 for indicating the charge and the bar-shaped item 607 for indicating the carbon emission amount may change a colored region thereof. In addition, the item 606 for indicating the charge may show a saving charge 625 against the previous month in view of the target charge. In addition, the item 607 for indicating the carbon emission amount may show a reduction amount of carbon emission against the previous month in view of the target charge inputted by the user. The carbon emission reduction amount may be displayed together with information on the number of planted trees having the same effect according to a given calculation rule. In addition, the terminal may display the user's target charge as an upper percentage (%) 630 compared to neighbors. When the terminal receives the target charge through the item 630 for receiving the target charge from the user, the terminal may transmit the target charge information to the server.
Specifically,
The terminal may display a circular item 700 in the center of the screen to compare the electricity charge budget information with the current electricity charge information. At the center of the circular item, current electricity charge information 710 may be displayed. Together with the current electricity charge information, information about the remaining days until charge settlement and information about the remaining budget corresponding to a difference between the target charge and the current electricity charge may be displayed. In addition, an indicator 720 for indicating the target charge information may be displayed in the twelve o'clock direction of the circular item 700. The indicator 720 may be a reference point for displaying the current electricity charge in the circular item 700.
The terminal may display the current electricity charge in the form of an arc 730 in the circular item 700. The length of the arc 730 may be determined depending on the ratio of the current electricity charge to the target charge. The length of the arc 730 may be calculated by multiplying the length of the circumference of the circular item 700 by the ratio of the current electricity charge to the target charge. In addition, the terminal may display a guide indicator 740 for indicating the current electricity charge budget information at the edge of the circular item 700. Using the electricity charge budget information per period generated by the server or terminal, the current electricity charge budget information may be derived. Then, the guide indicator may be displayed at a position away from the target charge indicator 720 by an angle derived by multiplying the ratio of the current electricity charge budget to the total target charge by 360 degrees.
Also, the terminal may display a grade 750 depending on target achievement probability at the top of the screen. That is, the grade may be obtained by dividing the ratio of the current electricity charge to the current electricity charge budget by a given period. The grade may include, for example, excellent, good, fair, need of saving, and the like. As another example, the grade may include awesome, great, good, bad, and the like.
Specifically, the terminal displays electricity charge budget information per period in the electricity usage status information generated by the terminal or received from the server, and current electricity charge information compared to the budget information.
First,
Specifically, in order to provide the user with electricity charge comparative information with other households, the server or terminal may generate a group from households adjacent to the user.
The group generated by the server or terminal may include a neighbor group and a similar group. The neighbor group refers to a group generated by extracting households within a predetermined radius from a place where the user is located. The server or terminal may generate the neighbor group by using the location information of the terminal.
Further, the similar group refers to a group generated by extracting households similar to a household to which the user belongs, in consideration of the characteristics of each household. The characteristics used for determining the similar group may include a zip code, the number of residents divided by age, the size of residence, and an applied rate system. The server may receive the characteristic information of the household from the gateway installed in each household. The terminal may receive the characteristic information of household from the server.
As shown in
As described above, a group for comparison of electricity charges is selected by extracting households being similar in characteristics to the user, rather than using only zip codes. Therefore, there is an effect that the user can make realistic comparison possible.
Specifically,
In addition to generating a similar group as shown in
Thereafter, at step S1025, the server calculates the user ranking in the generated user group cluster. Then, if the terminal updates the friend information at step S1030 and transmits this to the server 1005, the server may modify the user group cluster and recalculate the user ranking for the electricity saving charge at step S1035. Thereafter, the terminal 1000 may transmit a message for requesting ranking contention information at step S1040. In response to this, the server 1005 may transmit a ranking contention response message including the calculated ranking information to the terminal 1000 at step S1045. At step 1050, the terminal 1000 may display the received ranking contention information on the display.
