Description

  The present invention relates to a meter value verification device, and in particular, reads actual meter values of each meter related to consumption of building equipment and display meter values provided in a building equipment management device and reflecting the actual meter values, respectively. The present invention relates to a read meter value checking device for checking whether or not a display meter value of an equipment management device is an abnormal value.

  For example, equipment installed in buildings such as office buildings and factories is regularly read by workers of equipment management companies to read the actual meter value of each meter related to its consumption and the display meter value of the building equipment management device. And collated. This is because the amount of usage of the equipment is charged based on the display meter value of the building equipment management device, but if the display meter value displays a value different from the actual meter value, the charge will not be charged correctly. Because it becomes. This situation can generally occur due to an error in the initial setting of the display meter value, poor contact of the electrical wiring, or disconnection.

  For example, if the building is an office building or the like, the floor on which the actual meter related to this consumption is placed is different from the floor on which the display meter of the building equipment management device is placed. A difference occurs between the reading times of both. Moreover, the value of each meter regarding consumption of building equipment changes with progress of time. Therefore, if there is a difference in reading time between the actual meter and the display meter, both meter values may be different.

Therefore, the facility management company generally collates the reading operation of the actual meter value and the display meter value of each actual meter by arranging two workers on the actual meter and the display meter, respectively.
Even when two workers read both the actual meter and the display meter, there may be a slight time difference in reading. Therefore, it is determined whether or not both readings are within a predetermined error range, and if they are within the predetermined error range, it is determined that the display meter value reflects the actual meter value.

  On the other hand, Patent Document 1 discloses a fee calculation system. Here, for multiple child meters that measure the amount of usage at each location in the field facility, a parent meter is provided to measure the usage at each location, and the sum of the meter values of each child meter and the meter value of the parent meter It is described that the normality of the meter value of each child meter is confirmed when and match.

  Hereinafter, an embodiment of a meter value matching apparatus according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of one embodiment of the meter value matching device. The meter value verification device 1 includes a meter value input unit 2, a reading time recording unit 3, a display meter value storage unit 4, a variation model creation unit 5, and a meter value verification unit 6. In the present embodiment, a case will be described in which the building is an office building 11, the building facility is an air conditioning facility 10, and the consumption amount is the amount of electricity used. However, the building facility may be, for example, a water supply / drainage facility, and its consumption may relate to facilities such as water usage.

  An air conditioner 10 is provided in the office building 11, and an air conditioner (not shown) is provided on each floor of the office building 11. Each floor is provided with an actual meter 7 indicating the amount of electricity used by those air conditioners. On the other hand, the building equipment management device 9 is provided with a display meter 8 that reflects the meter value of each actual meter 7. The worker 12 performs an operation of collating the meter value of the display meter 8 that displays the power consumption of each air conditioner related to the air conditioner 10 of the office building 11 with the corresponding meter value of the actual meter 7.

  The meter value input unit 2 reads and inputs the actual meter value of each actual meter 7 related to the consumption of the building facility 10 and the display meter value of the display meter 8 of the building facility management device 9 by the operator 12. . The worker 12 reads the actual meter value of the actual meter 7 on the floor of the office building 11 and inputs it to the meter value verification device 1. And the display meter value of the display meter 8 arrange | positioned at the building equipment management apparatus 9 of the office building 11 is read and inputted into the meter value collation apparatus 1. The worker 12 individually inputs the meter values of a certain actual meter 7 and the corresponding display meter 8 together with the identification number of the actual meter 7. Note that the reading order may be either first or second.

  FIG. 2 shows reading values and reading times of the actual meter 7 and the display meter 8 recorded in the meter value collating apparatus 1. In the meter value verification device 1, the reading value of the actual meter 7, the reading value of the display meter 8, and the absolute value of the difference between these meter values are recorded. Further, the reading time recording unit 3 measures the reading time when the actual meter value and the display meter value are read, and calculates the time difference. For example, when the time when the actual meter value displayed on the actual meter 7 with the identification number 3F007 is read is PM19: 45 and the time when the displayed meter value of the display meter 8 is read is PM19: 55, the time difference is 10 minutes. The reading time and the time difference may be measured up to a second unit.

  The display meter value storage unit 4 stores history information of display meter values of the past building facility management device 9 of the office building 11. That is, the display meter value storage unit 4 stores a predetermined time interval of each display meter of the air conditioning equipment 10 in the past several years of the office building 11, for example, a meter value every 10 minutes.

  FIG. 3 shows a variation model of the daily electricity consumption in the air conditioner. In general, the amount of electricity used by an air conditioner tends to increase gradually in the morning, peak in the afternoon, and decrease from the evening. This fluctuation in electricity usage varies depending on the season and month of the year, and also varies depending on the outside temperature of the day. The fluctuation model creation unit 5 selects from the display meter value storage unit 4 a past day in which the reading of the meter value is similar to the past in which the ambient temperature, which is an environmental condition, is similar, and extracts the history information of the display meter value for that day. Then, a fluctuation model of the daily meter display value is created. That is, if the weather forecast for the day on which the meter value is read is cloudy throughout the day, the fluctuation model creating unit 5 is arranged around the day on which the meter value for the same month stored in the display meter value storage unit 4 is read. The day which was cloudy all day is extracted from the day. The extracted days may be extracted from a plurality of years, or a plurality of days may be selected from a certain year. The fluctuation model creation unit 5 creates a fluctuation model as shown in FIG. 3 from the fluctuation of the daily electricity usage in the extracted air conditioner.

  The meter value verification unit 6 confirms that the difference between the read actual meter value and the displayed meter value is within the threshold value set from the reading time and time difference in the variation model, and Check the displayed meter value. As shown in FIG. 2, the read actual meter value and the display meter value differ due to the read time difference. The meter value matching unit 6 calculates a difference between meter values predicted from the read reading time and time difference using the variation model shown in FIG. 3, and adds an error to the difference to set a threshold value. To do. For example, the case of the real meter 7 with the meter identification number 3F007 in FIG. 3 will be described. From the slope (A) of the curve of FIG. If 2 is added as a measurement error to this value, the threshold value is 6. The meter value verification unit 6 determines that the difference in meter value is 1 for the actual meter 7 with the meter identification number 3F007, and the meter value of the display meter 8 correctly reflects the meter value of the actual meter 7. On the other hand, in the case of the actual meter 7 with the meter identification number 4F003 in FIG. 2, the difference in the time difference of 6 minutes is 3 from the slope (B) of the curve in FIG. Calculated. If 2 is added as a measurement error to this value, the threshold value becomes 5. The meter value matching unit 6 determines that the difference in meter value is 11 for the actual meter 7 with the meter identification number 4F003, and the meter value of the display meter 8 does not correctly reflect the meter value of the actual meter 7.

  The fluctuation model creation unit 5 extracts a time zone with a low rate of fluctuation per hour from the created daily meter display value fluctuation model, and the meter value collation unit 6 determines the actual meter value and the display meter in that time zone. Read and check the value. That is, in FIG. 3, the curve slope in the early morning (C), the curve slope in the lunch break (D), the curve slope in the afternoon peak (E), and the curve slope in the night (F) Even if there is a difference in reading time, the influence is less. The fluctuation model creation unit 5 extracts a time zone having a small slope of the curve and shows it to the worker. The worker selects the time most suitable for the work among these time zones and performs the collation work of the meter value. Thus, for example, select a time zone with a low rate of change per hour, such as during the day when the meter value is peak or at night when the meter value is low, and check the actual meter value and the displayed meter value for verification. The collation between the actual meter value and the display meter value of the building equipment management device 9 can be accurately performed by one worker.
