(Embodiment 1)
FIG. 1 is a block diagram showing a schematic arrangement of an energy management system 1 according to an embodiment of the present invention. As shown in FIG. 1, the energy management system 1 according to the present embodiment is a HEMS (Home Energy Management System) that displays the amount of power consumed by the electrical device 100 to the user. The energy management system 1 calculates an amount of electric power based on electric equipment 100 that operates using electric power supplied via a power line (not shown) as a power source, and electric power information that represents an integrated value of electric power supplied to the electric equipment 100, And a data processing device 200 to be displayed. Electrical device 100 and data processing device 200 are connected to each other so that data can be transmitted and received.

  The electric device 100 is, for example, an air conditioner or a lighting device. Electric equipment 100 is supplied with electric power from a commercial power source (not shown) via a power line (not shown). The electric device 100 operates in accordance with an operation directly input by a user of the energy management system 1 and a request transmitted from the data processing device 200. In the present embodiment, the electrical device 100 measures the integrated value of the power supplied to the electrical device 100 via the power line, for example, every second. And according to the request | requirement from the data processor 200, the electric equipment 100 transmits the electric power information showing the integrated value of the measured electric power to the data processor 200 regularly, for example every 30 seconds.

  The data processing device 200 calculates and displays the amount of power supplied to the electrical device 100 via the power line per unit time based on the power information periodically acquired from the electrical device 100. This unit time is, for example, one hour, one day, one month, and one year. In addition, the data processing device 200 receives time information representing the current time on the network 400 from an NTP (Network Time Protocol) server 300 connected via the network 400 such as the Internet, and the received time information Based on this, an internal clock (timer 270 described later) in the data processing device 200 is corrected.

  Next, the hardware configuration of the data processing device 200 will be described. As shown in FIG. 1, the data processing device 200 includes a processor 210, a main storage unit 220, an auxiliary storage unit 230, a communication unit 240, an input unit 250, a display unit 260, and a time measuring unit 270. The main storage unit 220, auxiliary storage unit 230, communication unit 240, input unit 250, display unit 260, and timing unit 270 are all connected to the processor 210 via the internal bus 280.

  The processor 210 is composed of, for example, a CPU (Central Processing Unit). The processor 210 executes various processes by executing the program P1 stored in the auxiliary storage unit 230. The processing executed by the processor 210 includes calculation of the amount of power supplied to the electrical device 100 via the power line every unit time.

  FIG. 2 is a diagram schematically showing the amount of electric power per hour calculated by the processor 210. Each of the electric energy E8 to E14 in FIG. 2 is 8 o'clock (after 8:00:00 and before 9: 0), 9 o'clock (after 9:00:00 and before 10:00), ... This corresponds to the amount of power supplied to the electrical device 100 at each of the 14:00 range (after 14:00 and before 15:00). Also, the black circles in FIG. 2 indicate the integrated values at 0 minutes per hour.

  As shown in FIG. 2, the processor 210 supplies, to this unit time, a value obtained by subtracting the integrated value at the start time of this unit time from the integrated value at the end time (0 minutes per hour) of each unit time. It is calculated as the amount of electric power. For example, the processor 210 calculates a value obtained by subtracting the integrated value at 8:00:00 from the integrated value at 9:00:00 as the amount of power supplied for 1 hour in the 8 o'clock range.

  The processor 210 calculates the amount of power supplied in one day, the amount of power supplied in one month, and the amount of power supplied in one year in the same manner as the amount of power supplied in one hour. The start time and end time when one day is a unit time are 0:00 every day. The starting time and ending time when the month is a unit time are 0:00 on the first day of every month. The starting time and ending time when the unit time is one year is 0:00 on January 1 every year.

  Returning to FIG. 1, the main storage unit 220 includes, for example, a RAM (Random Access Memory). The main storage unit 220 loads the program P1 from the auxiliary storage unit 230. The main storage unit 220 is used as a work area for the processor 210.

  The auxiliary storage unit 230 includes a nonvolatile memory such as a hard disk or a flash memory. The auxiliary storage unit 230 supplies data used by the processor 210 to the processor 210 in accordance with an instruction from the processor 210, and stores the data supplied from the processor 210 and the like.

  The auxiliary storage unit 230 stores various data used for the processing of the processor 210 in addition to the program P1. The data stored by the auxiliary storage unit 230 includes a power history table 231 that indicates a time transition of an integrated value of power acquired from the electric device 100. The power history table 231 includes a plurality of combinations of an integrated value of power and a time when the integrated value is acquired.

  The communication unit 240 includes a communication interface for communicating with the electric device 100 and the NTP server 300. The communication unit 240 outputs data included in the received signal to the processor 210. Moreover, the communication part 240 acquires the data output from the processor 210, and transmits the signal containing this data to the electric equipment 100, for example.

  The input unit 250 includes a keyboard and pointing devices such as a mouse and a touch pad. The input unit 250 acquires information input by the user and outputs the information to the processor 210. The input unit 250 is used for switching an image displayed on the display unit 260 and inputting a control content for the electric device 100.

  FIG. 3 shows an example of a graph displayed on the display unit 260 at 15:10 on July 29, 2013. As shown in FIG. 3, the display unit 260 displays a bar graph g <b> 1 indicating the transition of the amount of power supplied every hour in the past.

  The timer unit 270 includes a timer that measures the current time, and functions as an internal clock in the data processing device 200. Based on the time information received from the NTP server 300, the current time measured by the time measuring unit 270 is corrected so as to be synchronized with the current time represented by the received time information.

  Next, a functional configuration of the processor 210 of the data processing device 200 will be described.

  FIG. 4 is a schematic block diagram illustrating a functional configuration of the processor 210 of the data processing device 200 according to the first embodiment of the present invention. As shown in FIG. 4, when the processor 210 executes the program P1 stored in the auxiliary storage unit 230, a time information acquisition unit 211, a notification determination unit 212, a power information acquisition unit 213, a calculation unit 214, a display determination unit 215, which functions as a display control unit 216.

  The time information acquisition unit 211 periodically acquires time information indicating the current time (second current time) on the network 400 from the NTP server 300. Then, the time information acquisition unit 211 measures the time when the current time (first current time) timed by the time measuring unit 270 is different from the second current time represented by the time information acquired from the NTP server 300. The first current time is corrected so as to be synchronized with the second current time represented by the time information acquired from the NTP server 300.

  The notification determination unit 212 determines whether or not the first current time measured by the time measuring unit 270 is different from the second current time acquired by the time information acquisition unit 211. If the notification determination unit 212 determines that the first current time is different from the second current time, the notification determination unit 212 outputs that fact to the display control unit.

  The power information acquisition unit 213 acquires power information representing the integrated value of power measured by the electrical device 100 from the electrical device 100 via the communication unit 240 periodically, for example, every 30 seconds. In addition, the power information acquisition unit 213 associates the first current time counted by the clock unit 270 when the power information is acquired with the power information as the time when the power information is acquired, and stores the power information in the auxiliary storage unit 230. Stored in the power history table 231.

  Based on the integrated value of power stored in the power history table 231 and the acquisition time, the calculation unit 214 calculates the amount of power supplied to the electrical device 100 via the power line every unit time. Further, when the first current time is corrected, the calculation unit 214 calculates the amount of power supplied per unit time before and after the correction.

  The display determination unit 215 determines whether or not there is an abnormality in the amount of power supplied per unit time calculated by the calculation unit 214. Specifically, the display determination unit 215 calculates the amount of electric power calculated based on the difference between the first current time measured by the timer unit 270 and the second current time acquired by the time information acquisition unit 211. Determine whether there is an abnormality.

  Here, the abnormality of the calculated electric energy determined by the display determination unit 215 will be described.

  FIG. 5A is a diagram showing an integrated value of power per unit time before and after correction of the first current time when the first current time is ahead of the second current time, and FIG. 5B is a display. 4 is an example of a graph representing the amount of power per unit time displayed on a unit 260. In the example shown in FIG. 5A, when the first current time is 11:45, 10:30 is acquired as the second current time. Therefore, in this example, there are two values for the amount of power at 11:00: a value acquired before correction and a value acquired after correction. In addition, the value acquired after the correction is the electric energy for a total of 75 minutes including 45 minutes from 11:00 to 11:45 before correction and 30 minutes from 10:30 to 11:00 after correction. Represents. Therefore, as shown in FIG. 5B, in the graph g2 representing the electric energy per unit time displayed on the display unit 260, the electric energy at 11:00 is corrected instead of the value acquired before correction. When the bar graph b2_11 having a value acquired later is displayed, a bar graph b2_11 that actually represents the amount of power for 75 minutes is displayed as the amount of power in one hour from 10:00 to 11:00.

  FIG. 6A is a diagram showing an integrated value of power per unit time before and after correction of the first current time when the first current time is ahead of the second current time, and FIG. 6B is a display. 4 is an example of a graph representing the amount of power per unit time displayed on a unit 260. In the example shown in FIG. 6A, when the first current time is 11:15, 10:45 is acquired as the second current time. Accordingly, in this example as well, as in the example shown in FIGS. 5A and 5B, there are two values for the electric energy at 11:00: a value acquired before correction and a value acquired after correction. It will be. In addition, the value acquired after the correction is the total amount of power for 30 minutes including the 15 minutes from 11:00 to 11:15 before the correction and the 15 minutes from 10:45 to 11:00 after the correction. Represents. Therefore, as shown in FIG. 6B, in the graph g3 representing the power amount per unit time displayed on the display unit 260, the power amount at 11:00 is corrected instead of the value acquired before correction. When the bar graph b3_11 having a value acquired later is displayed, a bar graph b3_11 that actually represents the amount of power for 30 minutes is displayed as the amount of power in one hour from 10:00 to 11:00.

  Therefore, as in the example shown in FIGS. 5 and 6 above, when there are two values before and after correction as the value of the electric energy in a certain unit time, that is, the first current time is greater than the second current time. When the second current time is before the time at which the latest unit time has elapsed, the display determination unit 215 determines that the calculated electric energy is abnormal.

  FIG. 7A is a diagram showing an integrated value of power per unit time before and after correction of the first current time when the first current time is ahead of the second current time, and FIG. 7B is a display. 4 is an example of a graph representing the amount of power per unit time displayed on a unit 260. In the example shown in FIG. 7A, when the first current time is 11:45, 11:15 is acquired as the second current time. Therefore, the electric energy at 12:00 is the total electric energy for 90 minutes including the 45 minutes from 11:00 to 11:45 before the correction and the 45 minutes from 11:15 to 12:00 after the correction. Calculated. Therefore, as shown in FIG. 7B, in the graph g4 representing the electric energy per unit time displayed on the display unit 260, the bar graph b4_12 actually indicating the electric energy for 90 minutes is displayed as the electric energy at 12:00. Is done.

  Therefore, as in the example shown in FIG. 7, when the amount of power in a certain unit time is calculated, the amount of power in a time exceeding the normal unit time of 60 minutes is calculated by combining the measurement time before and after correction. That is, when the first current time is ahead of the second current time and the second current time is later than the time when the latest unit time has elapsed, the display determination unit 215 calculates It is determined that the amount of power is abnormal.

  FIG. 8A is a diagram showing an integrated value of power per unit time before and after the correction of the first current time when the first current time is later than the second current time, and FIG. 4 is an example of a graph representing the amount of power per unit time displayed on a unit 260. In the example shown in FIG. 8A, when the first current time is 11:15, 11:45 is acquired as the second current time. Therefore, the power amount at 12 o'clock is 15 minutes from 11 o'clock to 11:15 before the correction and 15 minutes from 11:45 to 12 o'clock after the correction, for a total of 30 minutes. Calculated. Therefore, as shown in FIG. 8B, in the graph g5 representing the amount of power per unit time displayed on the display unit 260, a bar graph b5_12 actually representing the amount of power for 30 minutes is displayed as the amount of power at 12:00. Is done.

  Accordingly, as in the example shown in FIG. 8, when the amount of power in a certain unit time is calculated as the amount of power in a unit time, the measurement time before and after correction is combined and the amount of power in a time of less than 60 minutes that is a normal unit time is calculated. When the first current time is later than the second current time and the second current time is before the time at which the unit time of the first current time elapses, the display determination unit 215 calculates It is determined that there is an abnormality in the amount of power.

  FIG. 9A is a diagram showing an integrated value of power per unit time before and after the correction of the first current time when the first current time is delayed from the second current time, and FIG. 9B is a display. 4 is an example of a graph representing the amount of power per unit time displayed on a unit 260. In the example shown in FIG. 9A, when the first current time is 11:15, 12:45 is acquired as the second current time. Therefore, the amount of power at 12 o'clock is not calculated, and 15 minutes from 11 o'clock to 11:15 before correction and 15 minutes from 12:45 to 13 o'clock after correction are combined for a total of 30 minutes The amount of power is calculated as the amount of power at 13:00. Accordingly, as shown in FIG. 9B, in the graph g6 representing the electric energy per unit time displayed on the display unit 260, the bar graph representing the electric energy at 12:00 is not displayed, and the electric energy at 13:00 is displayed. Actually, a bar graph b6_13 representing the amount of power for 30 minutes is displayed.

  Accordingly, as in the example shown in FIG. 9, when the value of the electric energy in a certain unit time is missing and not calculated, that is, the first current time is later than the second current time, and the second current If the time is after the time at which the unit time of the first current time has elapsed, the display determination unit 215 determines that the calculated power amount is abnormal.

  Returning to FIG. 4, the display control unit 216 displays the amount of power supplied per unit time calculated by the calculation unit 214 on the display unit 260. In addition, when the notification determination unit 212 determines that the first current time and the second current time are different, the display control unit 216 displays the power amount supplied for each unit time before displaying it on the display unit 260. Notifying that there is a possibility that there is an abnormality in the amount of power displayed on unit 260. Further, when the display control unit 216 determines that the power amount calculated by the display determination unit is abnormal, the display control unit 216 indicates that the power amount to be displayed is abnormal when displaying the power amount supplied per unit time. A message to that effect is displayed on the display unit 260.

  Here, a display mode of the display unit 260 by the display control unit 216 when the notification determination unit 212 determines that the first current time and the second current time are different will be described. FIG. 10 shows an example of a notification that there is a possibility that the amount of power displayed on the display unit 260 may be abnormal. In FIG. 10, a message M <b> 1 is displayed on the display screen 261 of the display unit 260, “A time lag has occurred. There is a possibility that the displayed power amount data may be abnormal.”.

  Next, a display mode of the display unit 260 by the display control unit 216 when the display determination unit 215 determines that the calculated electric energy is abnormal will be described.

  FIG. 11 shows an example of a message indicating that there is an abnormality in the displayed electric energy. The message M2 illustrated in FIG. 11 is displayed when the display determination unit 215 determines that the first current time and the second current time are different as illustrated in FIG. 5A or 6A, that is, power in a certain unit time. This is displayed when it is determined that there is an abnormality in the calculated electric energy when there are two values before and after the correction. The message M2 prompts the user to select which of the corrected power amount data and the uncorrected power amount data to display. And the display control part 216 is displayed using the electric energy data selected by the user as the electric energy value in the unit time. FIG. 12 shows an example of a graph representing the power amount per unit time using the power amount data selected by the user. In the graph g7 shown in FIG. 12, the bar graph b7_11 representing the amount of power selected by the user is highlighted by being displayed in a different color from the other bar graphs.

  In FIG. 13, an example of the graph showing the electric energy for every unit time displayed on the display part 260 is shown. The graph g8 shown in FIG. 13 is corrected by the display determination unit 215 when the first current time and the second current time are different as shown in FIG. 7A, that is, as the value of the electric energy in a certain unit time. It is an example of a graph displayed when it is determined that there is an abnormality in the calculated electric energy when the electric energy in the time exceeding 60 minutes, which is a normal unit time, is calculated by combining the measurement time before and after. . In the graph g8 shown in FIG. 13, the bar graph b8_12 representing the amount of power in a time exceeding 60 minutes, which is a normal unit time, is highlighted by being displayed in a different color from the other bar graphs.

  When the first current time and the second current time are different as shown in FIG. 8A, the display determination unit 215 adjusts the measurement time before and after correction as the power amount value in a certain unit time. Even in the case where the amount of power in a time of less than 60 minutes, which is a normal unit time, is calculated, the bar graph representing the amount of power in the unit time is expressed in a color different from other bar graphs as in FIG. Is highlighted.

  In FIG. 14, an example of the graph showing the electric energy for every unit time displayed on the display part 260 is shown. The graph g9 shown in FIG. 14 shows that the display determination unit 215 has a case where the first current time and the second current time are different as shown in FIG. FIG. 11 is an example of a graph displayed when it is determined that there is an abnormality in the calculated electric energy when it is not calculated. In the graph g9 shown in FIG. 14, the value of the electric energy is missing at 12:00, and the region b9_12 where the bar graph indicating the electric energy is normally displayed is displayed in a color different from that of the other bar graphs, thereby emphasizing. In addition to being displayed, a message M3 indicating that data is missing is displayed.

  Next, the operation of the data processing apparatus 200 in this embodiment will be described.

  First, the flow of time synchronization processing executed by the data processing device 200 will be described. FIG. 15 is a flowchart illustrating an example of the flow of time synchronization processing executed by the data processing device 200. For example, the time synchronization process illustrated in FIG. 15 is started when the power of the data processing apparatus 200 is turned on.

  First, the time information acquisition unit 211 refers to the time measurement unit 270 and determines whether or not the first current time has reached a predetermined time for acquiring time information from the NTP server 300 (step S11). When it is determined that the first current time is not the predetermined time (step S11; No), the time information acquisition unit 211 is in a waiting state until it is determined that the first current time has reached the predetermined time.

  Next, when it is determined that the first current time has reached a predetermined time (step S11; Yes), the time information acquisition unit 211 acquires time information from the NTP server 300 via the communication unit 240 (step S11). S12).

  Next, the notification determination unit 212 determines whether or not the first current time measured by the time measuring unit 270 is different from the second current time represented by the time information acquired in step S12 (step S13). When it is determined that the first current time and the second current time are not different, that is, the same (Step S13; No), the process returns to Step S11.

When it is determined that the first current time and the second current time are different (step S13; Yes),
The display control unit 216 displays on the display unit 260 that there is a possibility that there is an abnormality in the amount of power displayed on the display unit 260 (step S14).

  Next, the time information acquisition unit 211 corrects the first current time measured by the time measuring unit 270 so as to be synchronized with the second current time (step S15). Then, the process returns to step S11.

  By repeating the processes of steps S11 to S15 described above, the data processing device 200 synchronizes the first current time measured by the timer unit 270 with the second current time acquired from the NTP server 300. In addition, when the first current time is different from the second current time, the data processing device 200 displays on the display unit 260 that there is a possibility that the power amount displayed on the display unit 260 may be abnormal. Notify

  Next, the flow of power amount acquisition processing executed by the data processing device 200 will be described. FIG. 16 is a flowchart illustrating an example of the flow of power amount acquisition processing executed by the data processing device 200. The power amount acquisition process illustrated in FIG. 16 is started, for example, when the power of the data processing apparatus 200 is turned on.

  First, the power information acquisition unit 213 refers to the clock unit 270 and determines whether or not the first current time has reached a predetermined time for acquiring power information from the electrical device 100 (step S21). When it is determined that the first current time is not the predetermined time (step S21; No), the power information acquisition unit 213 is in a waiting state until it is determined that the first current time has reached the predetermined time.

  Next, when it is determined that the first current time has reached a predetermined time (step S21; Yes), the power information acquisition unit 213 acquires power information from the electrical device 100 via the communication unit 240 (step S21). S22).

  Then, the power information acquisition unit 213 associates the first current time counted by the clock unit 270 when the power information is acquired in step S22 with the power information as the time when the power information is acquired, and stores the auxiliary information in the auxiliary memory.
