Referring to FIG. 2, the error correction method of the meter reading data includes detecting at least one of unloaded data and singular value data included in an energy profile (S100), and corrected according to the type of the meter reading data corresponding to the unloaded data. Loading the reading data into the energy profile (S200) and correcting the outlier data based on the loading data range included in the energy profile, and loading the corrected outlier data into the energy profile (S300). have. Steps S100, S200, and S300 may be performed by an error correction apparatus of reading data, and the error correction apparatus of reading data may refer to the
Here, the energy profile may include loading data, unloaded data, and the like, and the loading data may include outlier data and the like. Unloaded data means when no metering data is loaded.If the metering data does not exist due to the failure of meter reading, the metering data exists but is not loaded due to an error of the metering data itself. This may occur when the metering data exists but the metering data is not loaded due to an error (for example, an error of the AMR server 20 (see FIG. 1)). Singular value data may refer to metering data having an unusually large value or a small value compared to other metering data.
In detail, the apparatus for correcting error of meter reading data may receive an energy profile and a customer profile from at least one AMR server 20 (see FIG. 1), and may include the energy profile and the customer profile in an energy profile through analysis of the received energy profile and the customer profile. At least one of the unloaded data and the outlier data may be detected (S100).
The error correction apparatus of the meter reading data may analyze an arbitrary consumer profile to determine whether the consumer resides at the meter reading place (that is, the place where the usage amount is measured by the meter). If the consumer resides at the meter location, the error correction device of the meter data can analyze the energy profile that maps to any consumer profile, and the analysis results in a value of zero or less (i.e. any Value) can be detected as unloaded data. That is, the error correction apparatus of the meter reading data may detect, as unloaded data, data that satisfies both 'condition 1) a customer resides in the meter reading place and condition 2) a data presence having a value of' 0 'or less'.
On the other hand, the error correction device of the meter reading data can calculate the average value of the loading data included in the energy profile for any customer, and a value larger than twice the average value calculated among the loading data of the energy profile for any customer. The branch can detect the loaded data as outlier data. At this time, the threshold for detecting outlier data is not limited to the above description (ie, twice the average value).
If the unloaded data is present in the energy profile for any customer (S210), the error correction device of the meter data may read the corrected meter data according to the type of the meter data corresponding to the unloaded data. (S220, S230, S240, S250, S260).
Type 1: meter data = '0', meter flag ( flag ) = '0' (ie meter reading flag indicates first state)
When the error correction apparatus of the meter reading data may analyze the meter reading data corresponding to the unloaded data, and as a result, the value of the meter reading data corresponding to the unloaded data is '0' and the metering flag is '0' (S220), The error correction device of the meter data can analyze the reason why the meter data is not loaded. If the analysis result of the unloading reason determines that it is not loaded due to the error of the metering data itself, the error correction apparatus of the metering data may make a request for rereading the unloaded data to the AMR server 20 (see FIG. 1). (S250).
The error correction apparatus for reading data may receive re-reading data according to the re-reading request from the AMR server 20 (see FIG. 1), and may load the re-reading data in the energy profile (S260). In addition, the error correction apparatus of the meter reading data stores uncalibrated meter reading data (i.e., meter reading data corresponding to unloaded data) separately from reread data (i.e., corrected meter reading data) in a database (or energy Profile).
Type 2: meter data> '0', meter flag = '1' (i.e. meter flag indicates second state)
The error correction apparatus of the meter reading data may analyze the meter reading data corresponding to the unloaded data, and as a result, the value of the meter reading data corresponding to the unloaded data is greater than '0' and the metering flag is '1' (S230). The error correction apparatus of the meter reading data may determine the meter reading data (that is, meter reading data having a value larger than '0' and the meter flag '1') as corrected meter reading data.
The error correction apparatus of the meter data may load the corrected meter data (that is, meter data having a value greater than '0' and the meter flag '1') in the energy profile (S260).
Here, the metering data of 'type 2' may refer to metering data not yet loaded in the energy profile among the metering data re-read in correspondence to 'type 1'. That is, due to re-reading, the reading data value may have a value greater than '0' and the reading flag is changed from '0' to '1', so that the reading flag has a value larger than '0' and the reading flag is '1'. The meter reading data may refer to meter reading data that has been reread in correspondence with 'type 1'.
Type 3: meter data> '0', meter flag = '10 '(ie meter flag indicates third state)
The error correction apparatus of the meter reading data may analyze the meter reading data corresponding to the unloaded data, and as a result, the value of the meter reading data corresponding to the unloaded data is greater than '0' and the metering flag is '10' (S240). The error correcting apparatus of the meter reading data may determine the meter reading data (that is, meter reading data having a value greater than '0' and the meter flag '10') as the meter reading data corrected for the outlier data. That is, the metering data of type 3 may mean corrected metering data not yet loaded in the energy profile among the metering data corrected for the outlier data.
The error correction apparatus of the meter data may load the corrected meter data (that is, meter data having a value greater than '0' and the meter flag '10') into the energy profile. In addition, the error correction apparatus of the meter reading data may store uncorrected meter reading data (ie, outlier data) separately from the corrected meter reading data (or load the energy profile) in a database.
When outlier data exists in an energy profile for an arbitrary customer (S310), the error correction apparatus of the meter data may calculate a normal distribution of the energy profile having the outlier data (S320).
The error correction apparatus of the meter reading data may calculate a normal distribution based on the corresponding energy profile when the outlier data is related to the energy profile generated based on the meter reading data over time, and the outlier data may be stored in one day. According to the energy profile generated based on the meter reading data according to the normal distribution can be calculated based on the corresponding energy profile, and when the outlier data is related to the energy profile generated based on the meter data according to the month The normal distribution may be calculated based on the energy profile, and when the singular value data is generated based on the meter reading data according to the year, the normal distribution may be calculated based on the corresponding energy profile.
After calculating the normal distribution of the energy profile, the error correction apparatus of the meter reading data may correct the outlier data based on the normal distribution (S330). For example, if the normal distribution is related to an energy profile generated based on the reading data over time, the error correction device of the reading data may first analyze the time at which the outlier data is read, and the outlier data is generated. In the energy profile for the previous day of the day, the meter reading data can be detected at the same time as the outlier data is read, and the metering data for detecting the outlier data (that is, the same time as the time when the outlier data is read) Can be corrected with the meter reading data). Here, in order to correct the outlier data, the energy profile for the day before the day when the outlier data is generated is used, but the range of the energy profile used for correcting the outlier data is not limited to the above description.
After correcting the outlier data, the error correction apparatus of the meter reading data may determine whether an energy profile (that is, an energy profile including the corrected outlier data) for the corrected outlier data satisfies a preset criterion ( S340). That is, the error correction apparatus of the meter reading data may determine whether the maximum value of the energy profile for the corrected outlier data exceeds two times the average value of the energy profile for the corrected outlier data (ie, the maximum of the energy profile). Value ≤ 2 times the mean value of the energy profile). At this time, the threshold is not limited to the above description (ie, twice the average value).
If the energy profile for the corrected outlier data satisfies a preset criterion, the error correction device of the meter data may load the corrected outlier data into the energy profile, and the uncorrected outlier data may be corrected for the outlier. The data may be loaded in a database (or energy profile) separately from the data (S350).
On the other hand, if the energy profile for the corrected outlier data does not satisfy a preset criterion, the error correction apparatus of the meter data may perform the process of obtaining and analyzing the energy profile and the customer profile again (S100).
