Abstract

A method for predicting and correcting metering data in a non-metered section includes collecting energy-related metering data. The method includes generating, when a non-metered section occurs while collecting the metering data, predicted metering data for the non-metered section; and generating corrected metering data for the predicted metering data by analyzing history of the predicted metering data and collected metering data.

First claim

What is claimed is:

1. A method, performed by an integrated metering system including an integrated remote metering apparatus and a prediction and correction apparatus, for predicting and correcting metering data in a non-metered section, the method comprising:
collecting, by the integrated remote metering apparatus, actual energy-related metering data received from an automatic meter reading server, the actual energy-related metering data metered by a meter and transmitted from the meter to the automatic meter reading server;
detecting, by the integrated remote metering apparatus, a non-metered section within the collected actual energy-related metering data;
requesting, by the prediction and correction apparatus, metering data corresponding to the non-metered section to the automatic meter reading server and re-collecting re-transmitted actual energy-related metering data from the automatic meter reading server when the non-metered section is detected;
generating, by the prediction and correction apparatus, predicted metering data for the non-metered section when the metering data corresponding to the non-metered section does not exist within the re-transmitted actual energy-related metering data; and
generating corrected metering data for the non-metered section from the predicted metering data by analyzing the predicted metering data and the actual energy related metering data.

2. The method of claim 1 , wherein the non-metered section has a starting point and an end point, and wherein said generating the predicted metering data comprises:
generating a first function using metering data of a first section zone which is placed before the starting point of the non-metered section;
generating a second function using metering data of a second section zone which is placed after the end point of the non-metered section;
calculating an intersecting point of the first and second functions; and
calculating predicted metering data for each timing point of the non-metered section by generating a third function that passes through the calculated intersecting point, a first coordinate of the first function, and a second coordinate of the second function.

3. The method of claim 2 , wherein the first coordinate is an end portion of the first section zone and metering data of the end portion, and the second coordinate is a starting portion of the second section zone and metering data of the starting portion.

4. The method of claim 2 , wherein the non-metered section is a unit of hour, day, month or year.

5. The method of claim 1 , wherein said generating corrected metering data comprises:
correcting the predicted metering data by comparing the predicted metering data calculated with the previous metered data corresponding to the non-metered section or a history statistical value of the previous metered data corresponding to the non-metered section.

6. The method of claim 5 , wherein said generating corrected metering data comprises:
calculating a difference between the previous metered data or the history statistical value and the predicted metering data;
determining whether the difference is within a predetermined effective scope;
setting, when the difference is within the predetermined effective scope, the predicted metering data as metering data for the non-metered section; and
correcting, when the difference is not within a predetermined effective scope, predicted metering data of a portion which is not within the predetermined effective scope using the previous metered data or the maximum or minimum value of the history statistical value by comparing the predicted metering data of the portion which is not within the predetermined effective scope with the previous metered data or the history statistical value.

7. The method of claim 6 , wherein said correcting using the maximum or minimum value comprises:
correcting predicted metering data of the portion with the maximum value when predicted metering data of the portion having the difference is greater than the previous metered data or the history statistical value; and
correcting the predicted metering data of the portion with the minimum value when predicted metering data of the portion having the difference is equal to or smaller than the previous metered data or history statistical value.

8. The method of claim 6 , wherein the effective scope is calculated using the previous metered data or a standard deviation of the history statistical value.

9. An integrated metering system for predicting and correcting metering data in a non-metered section, the system comprising:
an integrated remote metering apparatus configured to collect actual energy-related metering data received from an automatic meter reading server and detect a non-metered section within the collected actual energy-related metering data, wherein the actual energy-related metering data is metered by a meter and transmitted from the meter to the automatic meter reading server;
a prediction and correction apparatus comprising:
a metering request unit configured to request metering data corresponding to the non-metered section to the automatic meter reading server and re-collect re-transmitted actual energy-related metering data from the automatic meter reading server when the non-metered section is detected;
a metering data prediction unit configured to generate predicted metering data for the non-metered section when the metering data corresponding to the non-metered section does not exist within the re-transmitted actual energy-related metering data; and
a correction unit configured to generate corrected metering data for the non-metered section from the predicted metering data by analyzing the predicted metering data and the actual energy related metering data.

10. The apparatus of claim 9 , wherein the non-metered section has a starting point and an end point, and wherein the predicted metering data generation unit is configured to:
generate a first function using metering data of a first section zone which is placed before the starting point of the non-metered section;
generate a second function using metering data of a second section zone which is placed after the end point of the non-metered section and then calculates an intersecting point of the first and second functions; and
generate a third function that passes through the calculated intersecting point, a first coordinate of the first function, and a second coordinate of the second function, thereby generating predicted metering data for each timing point of the non-metered section.

11. The apparatus of claim 10 , wherein the first coordinate is an end portion of the first section zone and metering data of the end portion, and the second coordinate is a starting portion of the second section zone and metering data of the starting portion.

12. The apparatus of claim 9 , wherein the correction unit is configured to correct the predicted metering data by comparing the predicted metering data calculated with the previous metering data corresponding to the non-metered section or a history statistical value of the previous metering data corresponding to the non-metered section.

13. The apparatus of claim 12 , wherein the correction unit is configured to calculate a difference between the previous metered data or the history statistical value and the predicted metering data, and determine whether or not to correct the predicted metering data by determining whether the difference is within a predetermined effective scope.

14. The apparatus of claim 13 , wherein the correction unit is configured to correct, when the difference is not within the predeterm
