Description

[Technical field]

[0001] The present disclosure relates to a display control device, a display control method, and a computer program. [Background technology]

[0002] The electricity charges for electricity consumed by consumers such as factories and homes are composed of a basic charge and a metered charge (see, for example, Patent Document 1). In order to reduce the electricity charge, it is necessary to reduce the basic charge or the metered charge. The metered charge is determined according to the power consumption. Therefore, the metered charge can be reduced by reducing the power consumption. On the other hand, the basic charge is determined by a contract with the power company, and is determined according to, for example, the maximum value of the average power consumption in 30-minute increments (power peak) over the past 13 months. Therefore, the basic charge can be reduced by reducing the power peak. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [Overview of the embodiment of the present disclosure] First, an overview of the embodiments of the present disclosure will be listed and described. (1) A display control device according to one embodiment of the present disclosure includes a receiving unit that receives a power consumption threshold, an extraction unit that extracts power consumption information indicating power consumption exceeding the threshold from power consumption information indicating power consumption for each specified time period, and a display control unit that executes a display process to display the power consumption indicated by the extracted power consumption information in association with a specified type related to the timing of power consumption measurement.

[0013] According to this configuration, the power consumption exceeding the threshold is displayed in association with the type. Therefore, the user can easily know the type for which measures should be taken to reduce peak power. This can support the user in planning effective measures to reduce electricity charges. .

[0014] (2) Preferably, the display control unit executes a display process for displaying the amount of power consumption indicated by the extracted power consumption information in a different manner for each time period during which power is consumed.

[0015] According to this configuration, the power consumption exceeding the threshold is displayed in association with the time period. This allows the user to easily know the time period during which peak power should be reduced. This helps the user to plan effective measures to reduce electricity bills.

[0016] (3) More preferably, the display control unit further executes a display process for displaying the amounts of power consumption indicated by the extracted power consumption information in descending order.

[0017] According to this configuration, the user can more easily know the time periods during which peak power consumption should be reduced, which is useful for planning measures to reduce peak power consumption.

[0018] (4) The display control unit may further execute a display process to display the number of pieces of power consumption information extracted for each combination of a first type and a second type selected from the month, time, and day of the week when power was consumed.

[0019] According to this configuration, the user can easily know the combination of the first type and the second type for which power should be reduced. For example, if the first type is the month and the second type is the day of the week, the user can easily know the combination of the month and the day of the week for which the power consumption exceeds the threshold. This can be useful for the user in planning measures to reduce peak power.

[0020] (5) The display control unit may further execute a display process to display the extracted power consumption information and the non-extracted power consumption information in different display modes in the form of a calendar corresponding to the days and days of the week on which electricity was consumed.

[0021] According to this configuration, the user can easily know the date and day of the week on which the power consumption exceeded the threshold, which can be useful for the user in planning measures to reduce peak power consumption.

[0022] (6) The display control unit may also execute a display process that displays an area where power consumption exceeds the threshold and an area where power consumption is equal to or less than the threshold in different display modes based on the extracted power consumption information.

[0023] According to this configuration, the user can easily know to what extent the power consumption has exceeded the threshold, which can be useful for the user in planning measures to reduce peak power consumption.

[0024] (7) The receiving unit may further receive the changed threshold value, the extraction unit may extract the power consumption information in response to the change of the threshold value, and the display control unit may execute the display process in response to the extraction of the power consumption information.

[0025] According to this configuration, when the threshold value is changed, the display process is executed in conjunction with the change. For example, by gradually increasing the threshold value, the user can narrow down the types of problems for which measures should be taken.

[0026] (8) A display control method according to another embodiment of the present disclosure includes a step of accepting a power consumption threshold, and selecting an image that exceeds the threshold from among power consumption information indicating power consumption for each predetermined time period. The method includes the steps of: extracting power consumption information indicating the amount of power consumption; and executing a display process to display the amount of power consumption indicated by the extracted power consumption information in association with a predetermined type related to the timing of measuring the amount of power consumption.

[0027] This configuration includes steps corresponding to characteristic processing units included in the above-mentioned display control device, and therefore, according to this configuration, it is possible to achieve the same effects and advantages as the above-mentioned display control device.

[0028] (9) A computer program according to another embodiment of the present disclosure causes a computer to function as a receiving unit that receives a power consumption threshold, an extraction unit that extracts power consumption information indicating power consumption exceeding the threshold from power consumption information indicating power consumption for each specified time period, and a display control unit that executes a display process to display the power consumption indicated by the extracted power consumption information in association with a specified type related to the timing of power consumption measurement.

[0029] According to this configuration, the computer can function as the above-mentioned display control device, and therefore, the same effects and advantages as those of the above-mentioned display control device can be achieved.

[0030] [Details of the embodiment of the present disclosure] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0031] <Overall configuration of power monitoring system> FIG. 1 is a diagram showing a configuration of a power monitoring system according to an embodiment. Referring to FIG. 1, a power monitoring system 100 includes a power monitoring server 1, an EMS (Energy Management System) device 2, a data collecting server 3, a database 4, a display device 5, and a terminal device 6.

[0032] The power monitoring server 1, the EMS device 2, the data collecting server 3, the database 4, and the terminal device 6 are connected to each other via a network such as the Internet or a LAN (Local Area Network).

[0033] The power monitoring server 1 functions as a display control device, and is a device for displaying the power usage status in consumer facilities such as factories and offices.

[0034] The EMS device 2 is connected to smart meters and power devices installed at multiple measurement points within the customer facility, and collects power consumption information at each measurement point.

[0035] The data aggregating server 3 receives power consumption information at each measurement point from the EMS device 2 according to a communication protocol such as FTP (File Transfer Protocol) or HTTPS (Hypertext Transfer Protocol Secure). The data aggregating server 3 classifies the received power consumption information by measurement point and stores it in the database 4. Note that the power monitoring server 1 may be provided with either or both of the data aggregating server 3 and database 4.

[0036] The database 4 is a storage device that stores power consumption information, and is configured, for example, by a NAS (Network Attached Storage), etc. Note that the power monitoring server 1 may also be provided with the database 4.

[0037] The power monitoring server 1 reads out the power consumption information stored in the database 4, and processes the power consumption information to display an image on the display device 5 or transmit the image to the terminal device 6.

[0038] The terminal device 6 displays the image received from the power monitoring server 1. In addition, the terminal device 6 transmits to the power monitoring server 1 data input by the user, such as threshold values, which will be described later.

[0039] <Example of power consumption information> 2 is a diagram showing an example of power consumption information stored in the database 4. The power consumption information indicates the amount of power consumption for each predetermined time period.

[0040] Referring to Fig. 2, the power consumption information includes an ID, a measurement point name, an equipment type, a parent ID, a measurement date and time, and an amount of power. The ID is an identifier for identifying a measurement point. The measurement point name indicates the name of the measurement point. The equipment type indicates the attributes of the power equipment connected to the measurement point, or the attributes of the measurement point itself. The equipment type includes, for example, a power receiving point, a power receiving station, a light / outlet, an air conditioner, a production facility, and others.

[0041] The parent ID is the ID of the measurement point that corresponds to the parent node when the measurement points are hierarchically organized into a tree structure. For example, the X factory consists of buildings A, B, and C. In other words, the power consumption at the X factory power receiving point with ID "1" is expressed as the sum of the power consumption at the A building power receiving station with ID "2", the power consumption at the B building power receiving station with ID "7", and the power consumption at the C building power receiving station with ID "12". For this reason, the parent ID of the measurement points with ID "2", ID "7", and ID "12" is set to "1". The power consumption at the A building power receiving station with ID "2" is expressed as the sum of the power consumption of the A building lighting with ID "3", the power consumption of the A building air conditioning with ID "4", the power consumption of the A building production equipment with ID "5", and the power consumption of the A building OA equipment with ID "6". For this reason, the parent ID of the measurement points with ID "3" to ID "6" is set to "2". Parent IDs are set similarly for the measurement points in buildings B and C.

[0042] The measurement date and time indicates the date and time when the power consumption was measured. The power amount indicates the measured power consumption. For example, at the measurement point with ID "1", the power consumption from 0:00 to 1:00 on January 1, 2017 is x(1), the power consumption from 1:00 to 2:00 on January 1, 2017 is x(2), the power consumption from 22:00 to 23:00 on January 31, 2019 is x(n-1), and the power consumption from 23:00 to 24:00 on January 31, 2019 is x(n). The measurement date and time and the power amount are similarly described for IDs "1" to "16", but are omitted from the illustration due to space limitations.

[0043] <Power monitoring server 1 configuration> FIG. 3 is a block diagram showing the configuration of the power monitoring server 1. As shown in FIG. With reference to FIG. 3, the power monitoring server 1 includes a reception unit 11, an extraction unit 12, and a display control unit 13.

[0044] The display control unit 13 causes the display device 5 to display the power consumption information stored in the database 4. The display control unit 13 may transmit an image of the power consumption information to the terminal device 6. In other words, the display control unit 13 may cause the terminal device 6 to display the power consumption information.

[0045] FIG. 4 is a diagram showing an example of a screen displayed on the display device 5. As shown in FIG. Referring to FIG. 4, display device 5 displays an analysis target field 20, an analysis period designation field 21, a threshold designation field 22, a measurement point display field 25, a power distribution field 26, an exceedance date and time field 27, and a number of exceedances field 28.

[0046] The analysis target field 20 is a field for specifying the time unit to be analyzed for the amount of power consumption. When the user presses button 20a with a mouse or the like, analysis is performed for a specific day. When the user presses button 20b, analysis is performed for a specific month. If none of the buttons are pressed, the analysis is performed on a yearly basis. Figure 4 shows the analysis screen on a yearly basis.

[0047] The analysis period designation field 21 is a field for designating an analysis period, and is provided with a field 21a for designating the start date of the analysis period and a field 21b for designating the end date. The analysis period designation field 21 is also provided with an execute button 21c, and an analysis of the designated analysis period is performed when the user presses the execute button 21c. In the example of FIG. 4, an analysis of the amount of power consumption for one year from January 9, 2018 to January 8, 2019 is performed.

[0048] The threshold specification field 22 is a field for the user to input a threshold. The threshold displayed in the threshold display field 24 changes when the user moves the slider 23 left or right, allowing the user to input a threshold. In the example of Fig. 4, a threshold of 90% is input. This threshold indicates a percentage of the maximum power consumption during the analysis period.

[0049] The measurement point display field 25 is a field for displaying the measurement points of the power consumption in a hierarchical structure. Although some of the measurement points are shown in FIG. 4, all the measurement points can be viewed by scrolling the measurement point display field 25. For example, the measurement point "X factory power receiving point" includes the measurement points "A building power receiving station" and "B building power receiving station." Furthermore, the measurement point "A building power receiving station" includes the measurement points "A building lighting," "A building air conditioning," "A building production equipment," and "A building OA equipment." The user can specify the measurement point to be analyzed by clicking the radio button provided to the left of any of the measurement point names. In the example of FIG. 4, the measurement point "X factory power receiving point" is specified as the measurement point.

[0050] The power distribution column 26 is a column showing the distribution of power consumption for each hour. FIG. 5 is a diagram showing an example of the distribution of the power consumption per hour displayed in the power distribution section 26. The horizontal axis represents time, and the vertical axis represents the power consumption. FIG. 5 is a bar graph in which the power consumption per hour from January 9, 2018 to January 8, 2019 is sorted in descending order of power consumption. In addition, the bar graphs of the power consumption during working hours (9:00-12:00, 13:00-17:00), break times (7:00-9:00, 12:00-13:00, 17:00-19:00), and nighttime (19:00-7:00) are shown in different display modes (for example, different colors, patterns, etc.). In addition, the position of the peak power consumption (2545.5 kWh) is shown by a dashed line. In addition, a peak enlargement button 31, a whole display button 32, a power consumption button 33, and a time series button 34 are shown. The meaning of each button will be described later.

[0051] Referring again to FIG. 4, the excess date and time column 27 displays a list of the excess dates and times when the power consumption threshold is exceeded.

[0052] 6 is a diagram showing an example of a threshold exceeding date and time displayed in the exceeding date and time field 27. The receiving unit 11 calculates the power consumption threshold from the ratio (%) of the power consumption to the maximum power consumption input in the threshold designation field 22 according to the following formula 1. Threshold = Maximum power consumption x percentage (%) / 100 ... (Formula 1)

[0053] In FIG. 6, some of the dates and times (six dates and times) when the threshold was exceeded are displayed. All of the dates and times when the threshold was exceeded can be viewed by scrolling the exceedance date and time column 27. For example, 16:00 on July 23, 2018 is displayed as the date and time when the threshold was exceeded. That day is a Monday, and the power consumption at that date and time is 2545.5 kWh. A month analysis button 35 and a day analysis button 36 are displayed to the right of each date and time. When the user presses the month analysis button 35, the power consumption for the month (for example, July 2018) corresponding to the exceedance date and time is displayed. When the user presses the day analysis button 36, the power consumption amount for the day corresponding to the exceedance date and time (for example, July 23, 2018) is analyzed.

[0054] Referring again to FIG. 4, the number of times of exceedance column 28 displays the number of times the amount of power consumption exceeded the threshold (hereinafter referred to as the "number of times of exceedance of threshold").

[0055] Fig. 7 is a diagram showing an example of the threshold exceedance count displayed in the exceedance count field 28. Fig. 7 is a diagram showing the threshold exceedance count two-dimensionally. Fig. 7 shows three combinations.

[0056] That is, the upper left of Figure 7 shows the number of times the threshold was exceeded for each combination of month and time. This shows that the threshold was exceeded between 10:00 and 17:00 in July and August. Of these, the number of times the threshold was exceeded was two each between 15:00 in July and 14:00 and 16:00 in August, and the number of times the threshold was exceeded was one at other times. It can also be seen that the number of times the threshold was exceeded in July was eight, and the number of times that the threshold was exceeded eight times was ten.

[0057] The bottom left of Figure 7 shows the number of times the threshold was exceeded for each combination of day of the week and time. This shows that the number of times the threshold was exceeded on Mondays was two each from 10:00 to 12:00 and from 14:00 to 17:00, and the number of times the threshold was exceeded on Tuesdays was one each from 15:00 and 14:00 to 16:00 on Thursday. It can also be seen that the number of times the threshold was exceeded on Mondays was 14, the number of times it was exceeded on Tuesdays was one, and the number of times it was exceeded on Thursdays was three.

[0058] The right side of Figure 7 shows the number of times the threshold was exceeded for each combination of month and day of the week. This shows that the number of times the threshold was exceeded on Mondays in July and August was 7, on Tuesdays in July was 1, and on Thursdays in August was 3. It also shows that the number of times the threshold was exceeded on Mondays was 14, on Tuesdays was 1, and on Thursdays was 3. In addition, in FIG. 7, the number of times the threshold was exceeded is 0 in the fields where no numerical value is entered.

[0059] 3, the reception unit 11 receives information input by the user by operating a keyboard, mouse, or the like connected to the terminal device 6 or the power monitoring server 1. For example, the reception unit 11 receives input data, thresholds, button input, and the like for various fields displayed in the analysis target field 20, analysis period designation field 21, threshold designation field 22, measurement point display field 25, power distribution field 26, and the like shown in FIG.

[0060] For example, the receiving unit 11 receives an analysis period for the power consumption information input in an analysis period designation field 21. The receiving unit 11 also receives a threshold value input by the user in a threshold designation field 22. As described above, in the threshold designation field 22, the user inputs a percentage (%) relative to the maximum power consumption. Therefore, the receiving unit 11 calculates a threshold value for the maximum power consumption based on the percentage and in accordance with Equation 1. The receiving unit 11 outputs the calculated threshold value to the extracting unit 12.

[0061] The extraction unit 12 receives the threshold value from the reception unit 11. The extraction unit 12 extracts, from the power consumption amount information stored in the database 4, power consumption information that indicates a power consumption amount that exceeds the threshold value.

[0062] The display control unit 13 performs display as shown in Fig. 4 to Fig. 7 based on the power consumption information stored in the database 4. When displaying the threshold exceeding date and time shown in Fig. 6 and the threshold exceeding count shown in Fig. 7, the display control unit 13 executes display processing based on the power consumption information extracted by the extraction unit 12.

[0063] <Power monitoring server 1 processing procedure> 8 to 10 are flowcharts showing the procedure of the process executed by the power monitoring server 1. FIG.

[0064] For example, when the user inputs an analysis period in the analysis period designation field 21 in FIG. 4 and presses the execute button 21c, the processing of the power monitoring server 1 is started. The reception unit 11 acquires the analysis period input in the analysis period designation field 21 (S1).

[0065] The extraction unit 12 extracts analysis target information, which is power consumption amount information for the acquired analysis period, from the database 4 (S2).

[0066] The receiving unit 11 receives the threshold value (proportion (%) of maximum power consumption) corresponding to the position of the slider 23 in the threshold value specification field 22, and calculates the power consumption threshold value according to Equation 1, thereby acquiring the threshold value (S3).

[0067] The extraction unit 12 extracts, from the analysis target information, power consumption information indicating a power consumption amount exceeding a power consumption threshold (S4).

[0068] The display control unit 13 displays the analysis target information in the power distribution field 26 shown in Fig. 4 (S5). That is, the display control unit 13 performs the display process as shown in Fig. 5.

[0069] The display control unit 13 displays the threshold exceeding date and time in the exceeding date and time field 27 shown in Fig. 4 based on the power consumption information in which the power consumption exceeds the threshold (S6). That is, the display control unit 13 performs the display process as shown in Fig. 6.

[0070] The display control unit 13 displays the number of times the threshold is exceeded in the number of times exceeding the threshold in the number of times exceeding the threshold, based on the power consumption information in which the power consumption exceeds the threshold (S7). That is, the display control unit 13 performs the display process as shown in FIG.

[0071] The reception unit 11 determines (S8) whether or not the user has changed the threshold by moving the slider 23 in the threshold specification field 22. If the threshold has been changed (YES in S8), the power monitoring server 1 returns control of the process to step S3.

[0072] If the threshold has not been changed (NO in S8), the reception unit 11 determines (S9) whether or not the user has specified an analysis period by inputting an analysis period in the analysis period specification field 21 and pressing the execute button 21c. If the user has specified an analysis period (YES in S9), the power monitoring server 1 returns control of the process to step S1.

[0073] If the analysis period is not specified (NO in S9), the reception unit 11 judges whether or not the peak enlargement button 31 has been pressed (S10 in Fig. 9). For example, the reception unit 11 judges whether or not the peak enlargement button 31 has been pressed on the power consumption distribution screen shown in Fig. 5. If the peak enlargement button 31 has been pressed (YES in S10), the display control unit 13 executes a peak enlargement display process for displaying the distribution of power consumption exceeding a threshold based on the power consumption information in which the power consumption exceeds a threshold (S11).

[0074] FIG. 11 is a diagram showing an example of an image displayed in the power distribution field 26 of the display device 5 in the peak enlargement display process. The horizontal axis represents time, and the vertical axis represents power consumption. FIG. 11 is a bar graph in which the power consumption for each hour that exceeds a threshold value (2291.0 kWh) is sorted in descending order of power consumption. In FIG. 11, the power consumption for working hours (9:00-12:00, 13:00-1 The diagram shows bar graphs of power consumption during the following periods: 7:00-7:00, break times (7:00-9:00, 12:00-13:00, 17:00-19:00), and nighttime (19:00-7:00) in different display modes (e.g., different colors, patterns, etc.). The position of the peak power consumption (2291.0 kWh) is shown with a dashed line. Also shown are a peak enlargement button 31, an overall display button 32, a power consumption button 33, and a time series button 34.

[0075] The reception unit 11 determines whether or not the whole display button 32 has been pressed (S12). For example, the reception unit 11 determines whether or not the whole display button 32 has been pressed on the screen shown in Fig. 11. If the whole display button 32 has been pressed (YES in S12), the display control unit 13 executes whole display processing to display the analysis target information (S13). For example, the display control unit 13 displays the distribution of power consumption during the analysis period as shown in Fig. 5 in the power distribution field 26.

[0076] The receiving unit 11 determines whether or not the chronological button 34 has been pressed (S14). For example, the receiving unit 11 determines whether or not the chronological button 34 has been pressed on the screen shown in Fig. 5. If the chronological button 34 has been pressed (YES in S14), the display control unit 13 executes a chronological display process that displays the analysis target information in chronological order (S15).

[0077] FIG. 12 is a diagram showing an example of an image displayed in the power distribution field 26 of the display device 5 in the time series display process. The horizontal axis represents time, and the vertical axis represents power consumption. The display control unit 13 displays the time series distribution of power consumption in the analysis period as shown in FIG. 12 in the power distribution field 26. FIG. 12 is a bar graph showing the power consumption for each hour from January 9, 2018 to January 8, 2019 in a time series. Note that the bar graphs of the power consumption for working hours (9:00-12:00, 13:00-17:00), break times (7:00-9:00, 12:00-13:00, 17:00-19:00), and nighttime (19:00-7:00) are displayed in different display modes (for example, different colors, patterns, etc.). However, in FIG. 12, due to the paper resolution, the bar graphs for each time period are displayed in the same display mode. 12, the position of the peak power amount (2291.0 kWh) is indicated by a dashed line. Also shown are a peak enlargement button 31, an overall display button 32, a power amount button 33, and a time series button .

[0078] When the time series button 34 is pressed on the screen shown in FIG. 11, the display control unit 13 displays the power amount information exceeding the threshold in time series.

[0079] The reception unit 11 determines whether the power amount button 33 has been pressed (S16).

For example, the power breakdown table 48 shows the power consumption of the measurement points "A-building power receiving station", "B-building power receiving station" and "C-building power receiving station" as 1515.6 kWh, 680.5 kWh and 346.1 kWh, respectively, as a breakdown of the power consumption of 2542.2 kWh at the measurement point "X-factory power receiving point". In addition, it is shown that the ratios of these to the power consumption of 2542.2 kWh are 59.62%, 26.77% and 13.61%, respectively.

[0097] <Effects of the embodiment> As described above, according to the present embodiment, the amount of power consumption exceeding the threshold is displayed in association with the type. For example, as shown in FIG. 11, the amount of power consumption exceeding the threshold is displayed in association with the type of power consumption. The power consumption is displayed in association with the time period during which peak power is consumed (hours, break time, or nighttime). This allows the user to easily know the time periods during which peak power should be reduced. This can assist the user in planning effective measures to reduce electricity bills. Also, as shown in FIG. 11, the power consumption is displayed in a different manner for each time period during which power was consumed. This allows the user to easily know the time periods during which peak power should be reduced.

[0098] Moreover, the power consumption is displayed in descending order as shown in Fig. 11. This allows the user to more easily know the time periods during which peak power consumption should be reduced.

[0099] In addition, the number of pieces of power consumption information extracted is displayed for each combination of the first type and the second type selected from the month, time, and day of the week when power was consumed, as shown in Fig. 7. This allows the user to easily know the combination of the first type and the second type for which power should be reduced.

[0100] Also, as shown in Fig. 13, the power consumption exceeding the threshold and the power consumption below the threshold are displayed in different display modes in the form of a calendar associated with the days and days of the week on which the power was consumed. Specifically, the area of ​​the power consumption exceeding the threshold and the area of ​​the power consumption below the threshold are displayed in different display modes. This allows the user to easily know the days and days on which the power consumption exceeded the threshold. Also, the user can easily know to what extent the power consumption exceeded the threshold.

[0101] Furthermore, when the threshold value is changed, a display process is executed in conjunction with the change by the display control unit 13. This allows the user to narrow down the types for which measures should be taken, for example, by gradually increasing the threshold value.
