<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of a power monitoring system according to an embodiment. The power monitoring system 1 includes a management device 10 and a plurality of watt hour meters 31, 32, and 33. In the following description, the watt hour meters 31, 32, and 33 may be collectively referred to as the watt hour meter 30.

  The watt-hour meter 30 is classified according to use or installation location. In this embodiment, the watt-hour meter 30 is classified according to use, and the watt-hour meters 31, 32, and 33 collect wiring for lighting equipment, wiring for air conditioning equipment, and wiring for kitchen equipment, respectively.

  The management device 10 is configured by a personal computer or the like, and a communication unit 12, a display unit 13, an operation unit 14, and a storage unit 15 are connected to a control unit 11 including a CPU that controls each unit. The communication unit 12 communicates with each watt hour meter 30. The display unit 13 displays an operation screen of the management apparatus 10, a management screen 20 (see FIG. 2), and the like. The operation unit 14 performs an input operation using a keyboard, a mouse, or the like. The storage unit 15 includes a RAM, a ROM, a hard disk drive, and the like. The storage unit 15 stores the operation program of the management device 10 and various data, and temporarily stores the calculation result of the control unit 11.

  The management device 10 acquires the power output from the watt hour meter 30 through communication between the communication unit 12 and each watt hour meter 30. Thereby, the output of each watt-hour meter 30 can be totaled, and the electric power consumption inside a building etc. can be monitored.

  At this time, the management apparatus 10 stores the power usage output from the watt hour meter 30 in the storage unit 15 according to measurement time periods obtained by subdividing one day into a predetermined time. Thereby, the power usage amount for each measurement time zone in the past can be read from the storage unit 15 and the management screen 20 (see FIG. 2) showing the power usage amount for each measurement time zone can be displayed on the display unit 13. . It is desirable that the measurement time zone is set to 30 minutes or 60 minutes, which is set to the time width used for the time distribution of power supply and demand and the time width for detecting the amount of power in the power charge, because analysis by the power monitoring system 1 becomes easy. In addition, when the electric power usage amount for every measurement time slot | zone is displayed on the display part 13, an electric power usage amount is displayed as an average value of the electric power usage in the applicable measurement time slot | zone.

  FIG. 2 is a diagram showing a management screen 20 based on the power consumption for each measurement time zone. The management screen 20 is provided with a list display unit 21 for displaying a list of past days in a calendar format. Below the list display unit 21, a target setting unit 22 is provided for inputting a target value for the amount of power used within the measurement time zone by means of the operation unit 14.

  Below the target setting unit 22, a selection unit 23 is provided for selecting the watt hour meters 31, 32, and 33 for performing the smoothing process using the operation unit 14. Although details of the smoothing process will be described later, the power consumption for each watt hour meter 30 in a plurality of measurement time zones is averaged and smoothed. The selection unit 23 is formed by a plurality of check boxes having labels of “illumination”, “air conditioning”, and “kitchen” corresponding to the watt-hour meters 31, 32, and 33, respectively.

  Table 1 shows an example of the power usage data stored in the storage unit 15 and the determination result of the achievement status with respect to the target value. The table reads the power consumption of the watt hour meter 31 for lighting equipment dated 7/14 and 7/15, the watt hour meter 32 for air conditioning equipment, and the watt hour meter 33 for kitchen equipment by measurement time zone. Contains the published data. Moreover, the measurement time zone is set to 30 minutes.

  When the 7/14 target value is 31.0 kW, the total power consumption of the watt hour meters 31, 32, 33 exceeds the target value between 11:30 and 13:30. For this reason, the overall comprehensive judgment is not achieved (indicated by “x”). When the target value of 7/14 is 33.0 kW and 33.2 kW, the total power usage amount of the watt hour meters 31, 32, 33 exceeds the target value between 12:30 and 13:00. For this reason, the comprehensive judgment for one day is not achieved.

  When the 7/15 target value is 31.0 kW, the total power consumption of the watt hour meters 31, 32, 33 exceeds the target value between 11:30 and 13:30. For this reason, the comprehensive judgment for one day is not achieved. When the target value of 7/15 is 33.0 kW and 33.2 kW, the total power consumption of the watt hour meters 31, 32, 33 between 12: 0 to 12:30 and 13: 0 to 13:30 Exceeds the target value. For this reason, the comprehensive judgment for one day is not achieved.

  The management screen 20 of FIG. 2 described above shows a state in which the smoothing process is not performed when the target value of the power consumption is 31.0 kW. According to this, the 1st mark which made the character bold is displayed with respect to the date (7/3, 7/7, 7/8, 7/14, 7/15) where comprehensive judgment is not achieved. You may display a 1st mark with the other character decoration, the change of a foreground color, a background color, etc. with respect to the date which a target is not achieved.

  Further, the management screen 20 in FIG. 3 shows a state in which the watt hour meters 31, 32, and 33 are subjected to the smoothing process when the target value of the power consumption is 31.0 kW. A second mark with a letter underlined is displayed for the date (7/3) when the comprehensive judgment is switched to the achievement of the target. You may display a 2nd mark by the change of a foreground color, a background color, etc. with respect to the date of goal achievement. As shown in Table 1, since the average daily power consumption for July 14 and July 15 exceeds 31.0 kW, the overall determination fails to achieve the target even if the smoothing process is performed.

  The management screen 20 of FIG. 4 shows a state where the smoothing process is not performed when the target value of the power consumption is 33.2 kW. According to this, the 1st mark which made the character bold is displayed with respect to the date (7/8, 7/14, 7/15) where comprehensive judgment is not achieved.

  At this time, when a date is selected by operating the mouse or the like, a breakdown screen shown in FIG. 5 is displayed. The figure shows a breakdown screen of 7/14. On the breakdown screen, the power consumption of each watt-hour meter 30 and the total thereof are displayed in a graph for each measurement time zone on the selected day. In the figure, the broken line indicates the target value. Thereby, the user can grasp | ascertain the breakdown of electric power consumption easily. A breakdown screen may be created as a table.

  As described above, when the watt hour meter 30 is selected by the selection unit 23 of the management screen 20, the result of the smoothing process is displayed. In the smoothing process, the power consumption corresponding to the selected watt-hour meter 30 is averaged and smoothed during a predetermined first smoothing period and second smoothing period. The first smoothing period is set to a measurement time zone that exceeds the target value, and the second smoothing period is set to a measurement time zone that is adjacent before and after the first smoothing period. You may set a 2nd smoothing period to the measurement time slot | zone adjacent to only one before and behind a 1st smoothing period.

  For example, in the case of 7/14 shown in the above-mentioned Table 1, when the target value is 33.2 kW, the target value is exceeded in the measurement time zone from 12:30 to 13:00. Therefore, 12:30 to 13:00 are the first smoothing period, and 12: 0 to 12:30 and 13: 0 to 13:30 are the second smoothing period. Only one of 12: 0 to 12:30 and 13: 0 to 13:30 may be used as the second smoothing period.

  Moreover, when the measurement time slot | zone exceeding a target value continues, the several measurement time slot | zone which exceeded the target value continuously is set to a 1st smoothing period. The second smoothing period is set to a measurement time zone adjacent before and after the first smoothing period. You may set a 2nd smoothing period to the measurement time slot | zone adjacent to only one before and behind a 1st smoothing period. At this time, when the first and second smoothing periods are shorter, the power usage can be easily dispersed according to the result of the smoothing process. For this reason, when the first smoothing period exceeds a predetermined time (for example, 3 hours), warning notification that prompts resetting of the target value may be performed.

  In addition, when the adjacent measurement time zone exceeds the target value for the measurement time zone that exceeded the target value, the measurement time zone that exceeded the target value after the measurement time zone that exceeded the previous target value Is set as the first smoothing period. At this time, the second smoothing period is set to a measurement time zone adjacent before and after the first smoothing period. You may set a 2nd smoothing period to the measurement time slot | zone adjacent to only one before and behind a 1st smoothing period. Thereby, it is possible to prevent the measurement time zones between the measurement time zones exceeding the target value from being overlapped and smoothed, and to facilitate the analysis after the smoothing process.

  For example, in the case of 7/15 shown in the above-mentioned Table 1, when the target value is 33.2 kW, the target value is exceeded in the measurement time zones of 12: 0 to 12:30 and 13: 0 to 13:30. For this reason, 12: 0 to 13:30 is the first smoothing period, and 11:30 to 12:00 and 13:30 to 14:00 are the second smoothing period. Only one of 11:30 to 12:00 and 13:30 to 14:00 may be used as the second smoothing period.

  A plurality of continuous measurement time zones including a measurement time zone exceeding the target value is set as the first smoothing period, and a plurality of continuous measurements including the measurement time zones adjacent to each other before and after the first smoothing period. The time zone may be set to the second smoothing period. Further, the second smoothing period may be a plurality of continuous measurement time zones including a measurement time zone adjacent only before the first smoothing period, or a plurality of continuous time zones including a measurement time zone adjacent only after the second smoothing period. It may be a measurement time zone. At this time, when the first and second smoothing periods are shorter, the power usage can be easily dispersed according to the result of the smoothing process. For this reason, the total of the first and second smoothing periods may be within 4 hours, for example.

  Moreover, although the smoothing process is performed by averaging the power consumption amounts in the first and second smoothing periods, smoothing may be performed by other methods. For example, the smoothing process may be performed by replacing the power usage amount in the first smoothing period and the power usage amount in the second smoothing period of the watt-hour meter 30 selected by the selection unit 23.

  Table 2 is an example of the result of performing the smoothing process when the target value of the power consumption is 33.2 kW with respect to the data in Table 1. The table shows that when 7/14 and 7/15 are subjected to the smoothing process for the watt hour meter 31 for lighting equipment, the watt hour meter 32 for air conditioning equipment, and the watt hour meter 33 for kitchen equipment, the air conditioning equipment When it is performed only for the watt-hour meter 32 for the kitchen, when it is performed only for the watt-hour meter 33 for the kitchen equipment, the watt-hour meter 32 for the air conditioning equipment and the watt-hour meter 33 for the kitchen equipment The amount of power used and the determination result are shown.

  As shown in FIG. 6, when “illumination”, “air conditioning”, and “kitchen” are selected by the selection unit 23, the result of smoothing the watt hour meters 31 to 33 based on Table 2 is as follows. It is displayed on the management screen 20. Thereby, the second mark (underline) is displayed on the date (7/8, 7/14, 7/15) when the comprehensive determination is switched to the achievement of the target on the management screen 20 of FIG.

  Thereby, the user can easily determine that the target value can be achieved by smoothing for all the past days. At this time, for example, when a date of 7/14 is selected, a breakdown screen shown in FIG. 7 is displayed, and the power achievement target achievement status can be grasped in more detail.

  For further analysis, when only “air conditioning” is selected by the selection unit 23 as shown in FIG. 8, the result of smoothing the watt hour meter 32 based on Table 2 is displayed on the management screen 20. Is displayed. Accordingly, the second mark (underline) is displayed on the date (7/8) when the comprehensive determination is switched to the achievement of the target on the management screen 20 of FIG. Thereby, it can be easily determined that the target value cannot be achieved by the distribution of the power use of only the air conditioners for 7/14 and 7/15. At this time, for example, when a date of 7/14 is selected, a breakdown screen shown in FIG. 9 is displayed.

  As shown in FIG. 10, when only “kitchen” is selected by the selection unit 23, the result of smoothing the watt hour meter 33 based on Table 2 is displayed on the management screen 20. Accordingly, the second mark (underline) is displayed on the date (7/8) when the comprehensive determination is switched to the achievement of the target on the management screen 20 of FIG. Thereby, it can be easily determined that the target value cannot be achieved by the distribution of the power usage of only the kitchen appliances for 7/14 and 7/15. At this time, for example, when a date of 7/14 is selected, a breakdown screen shown in FIG. 11 is displayed.

  As shown in FIG. 12, when “air conditioning” and “kitchen” are selected by the selection unit 23, the result of smoothing the watt hour meters 32 and 33 based on Table 2 is the management screen 20. Is displayed. As a result, the second mark (underline) is displayed on the date (7/8, 7/14/7/15) when the overall determination is switched to the achievement of the target on the management screen 20 of FIG.

  Thereby, the user can easily determine that the target value can be achieved by distributing the power usage to the air conditioner and kitchen appliance for all past days. At this time, for example, if the date 7/14 is selected, a breakdown screen shown in FIG. 13 is displayed.

  According to the present embodiment, a desired watt-hour meter 30 is selected by the operation unit 14, and the first smoothing period including the measurement time period exceeding the target value and the first measurement period including the measurement time period adjacent to the first smoothing period. A smoothing process for smoothing the amount of power used in the two smoothing periods is performed on the selected watt-hour meter 30. Thereby, the analysis for disperse | distributing electric power use according to the watt-hour meter 30 according to an application, an installation place, etc. can be performed easily. Therefore, the convenience of the power monitoring system 1 can be improved.

  Moreover, the 1st smoothing period is set to the several measurement time slot | zone which exceeded the target value 1 or continuously, and the 2nd smoothing period is set to the measurement time slot | zone adjacent before and behind the 1st smoothing period. Thereby, the first and second smoothing periods are set to a short time, and it is possible to easily distribute the power usage based on the result of the smoothing process.

  In addition, when the adjacent measurement time zone exceeds the target value for the measurement time zone that exceeded the target value, the measurement time zone that exceeded the target value after the measurement time zone that exceeded the previous target value Are set as the first smoothing period. Thereby, it is possible to prevent the measurement time zones between the measurement time zones exceeding the target value from being overlapped and smoothed, and to facilitate the analysis after the smoothing process.

  In addition, the management screen 20 has a list display unit 21 for displaying a list of each day, displays a first mark such as a bold letter on a day including a measurement time zone that exceeds the target value, and performs each measurement time zone by smoothing processing. A second mark such as an underline different from the first mark is displayed for the day when becomes lower than the target value. Thereby, the achievement status of the target value can be easily determined.

  In addition, when a date is selected on the management screen 20, a breakdown screen for the day is displayed, so that it is possible to grasp the power usage target achievement status in more detail.

  Further, the measurement time zone is set to 30 minutes or 60 minutes, and the smoothing process averages the power usage amount in the first smoothing period and the power usage amount in the second smoothing period. Thereby, it is possible to easily perform an analysis for distributing the power usage corresponding to the time width of the time distribution of the power supply and demand and the time width of the power amount detection of the power charge.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the electric power monitoring system which monitors the electric power usage detected by the watt-hour meter.
