Problems solved by technology

[0008] In the case of Patent Document 1, when missing measurements occur consecutively at multiple times, the supplementary values ​​are all the same value, which cannot reflect changes in energy usage at each time. Therefore, although it is used for energy management There is no problem in the application, but there is a problem that it is not suitable for situations such as energy-saving applications that require high-precision values ​​at each time.
[0009] In the case of Patent Document 2, according to the total energy consumption, the usage amount at the location where the missing measurement occurs is supplemented according to the distribution ratio. Therefore, when the missing measurement period spans multiple times, there is the following problem, that is, it cannot Complements the energy usage at each moment with high precision, and is not suitable for energy-saving purposes, etc.
[0010] In the case of Patent Document 3, by combining the energy usage pattern (pattern) immediately before the occurrence of the missing measurement, weather conditions (obtained by setting), etc., similar to those previously saved Combining docking to complete the missing data, therefore, there is a problem that the missing data cannot be completed with high precision when the pattern of energy usage in the missing period is not similar to the previous one. Therefore, Not suitable for energy-saving purposes, etc.

Embodiment approach 1

[0031] In Embodiment 1 of the present invention, the data collection device collects the data of energy usage from all measurement positions of the data collection object, and saves the collected data in the built-in storage device. Based on the data saved in advance, the measured position similar to the pattern obtained by extracting the measurement position with similar energy usage over time, the energy usage amount during the missing measurement period of the missing position is supplemented, and the data used for the completion Only the similar pattern measurement position and the energy usage of the similar pattern measurement position for a period corresponding to the lack of measurement do not need to search for similar patterns from a large amount of previously stored data like in the prior art, and can use a low-cost low-cost During the missing period, the CPU can perform high-precision complementation even for a strange energy usage pattern that does not exist in the...

Embodiment approach 2

[0075] In Embodiment 2 of the present invention, the method for supplementing the missing data is to supplement the missing data at the measurement positions in the data collection system that uses the data collection device to collect the energy usage measured at a plurality of measurement positions respectively. The complete missing measurement data complement method, when the missing measurement occurs, the variation pattern of the energy usage is similar to the variation pattern of the energy usage of the measurement location where the missing measurement occurs, and the missing measurement period Calculate the energy usage increase / decrease value or the energy usage amount increase / decrease value ratio for each measurement time interval during the corresponding period, and use the calculated energy usage amount increase / decrease value or energy usage amount increase / decrease value ratio to calculate the The energy usage at each measurement time interval during the missing ...

Embodiment approach 3

[0086] On the basis of the missing data complementing method in Embodiment 1, the missing data complementing method in Embodiment 3 of the present invention is to set priority levels for the plurality of measurement positions, and the occurrence occurs at a measurement position with a higher priority level. In the case of a missing measurement, a period corresponding to the missing measurement period at a measurement location where the fluctuation pattern of the energy usage amount of the next priority level is similar to the variation pattern of the energy usage amount of the measurement location where the missing measurement occurred Calculate the energy usage ratio of each measurement time interval, and use the calculated energy usage ratio to calculate the energy usage amount of each measurement time interval during the missing measurement period, and complete the missing measurement data, The data collection device sets priority levels for the plurality of measurement loca...

Abstract

Even though missing measurement occurs, the missing data can be complemented in high precision. Provided is a missing data complementation method. A data collection device (1) is used to collect missing data on measuring positions in a data collection system, and the data is complemented, and in the data collection system, energy usage amount of a plurality of measuring positions (31, 31,...3n) is respectively measured. When missing measurement occurs, energy usage amount rate of each measuring time interval during a period which is equivalent to a missing measurement period is calculated, the variation patterns of the measuring positions of the energy usage amount are similar to the variation patterns of the energy usage amount of the measuring positions where missing measurement occur, and using the calculated energy usage amount rate to calculate energy usage amount of each measuring time interval of the missing measurement period, so as to complement the missing data.

Description

technical field [0001] The present invention relates to a missing measurement data complement method and a data collection device. The missing measurement data completion method uses the data collection device to collect the measurements in a data collection system of energy usage measured at a plurality of measurement positions respectively. Missing data completion at position. Background technique [0002] As a conventional method of complementing missing data, there is a technique that calculates the energy usage of the missing location based on the cumulative value before and after the missing location, or uses the time of multiple locations earlier than the missing location. The ratio of the energy usage to the energy usage is calculated to calculate the energy usage of the missing position (for example, refer to Patent Document 1). [0003] Also, based on the history information of the total energy consumption, the energy usage amount at the missing position is calcul...
