Energy monitoring device and control method therefor, and energy monitoring program

A method that controls an energy monitoring device to compute an amount of energy to be reduced within an energy consumed by equipment, the method comprising:

• acquiring, by a processor, time-series data of a physical quantity related to the consumed energy;
• pre-storing waveform model information indicating a waveform model of single-cycle time-series data, wherein the single-cycle time-series data is time-series data in a single-cycle from a start to an end of a predetermined process by the equipment;
• detecting, by a processor, the single-cycle time-series data within a predetermined period from the acquired time-series data;
• determining whether or not the single-cycle time-series data is detected;
• dividing, by a processor, the detected single-cycle time-series data detector into an added-value creating portion and an unproductive portion, only when it is determined that the single-cycle time-series data is detected, wherein the added-value creating portion creates an added-value in the predetermined process, and the unproductive portion does not produce any added-value in the predetermined process;
• and
• computing, by a processor, an amount of energy consumed in the unproductive portion as the amount of energy to be reduced, wherein
• the detecting of the single-cycle time-series data extracts waveform feature data from the acquired time-series data, performs pattern matching between the waveform feature data and the waveform model information stored in the memory, and detects the single-cycle time-series data in which the waveform feature data matches the waveform model information.

A non-transitory computer readable storage medium having computer instructions stored thereon comprising an energy monitoring program that operates an energy monitoring device to compute an amount of energy to be reduced within an energy consumed by equipment, the program causing a computer to perform:

• acquiring time-series data of a physical quantity related to the consumed energy;
• re-storing waveform model information indicating a waveform model of single-cycle time-series data, wherein the single-cycle time-series data is time-series data in a single-cycle from a start to an end of a predetermined process by the equipment;
• detecting the single-cycle time-series data within a predetermined period from the acquired time-series data;
• dividing the detected single-cycle time-series data into an added-value creating portion and an unproductive portion, only when it is determined that the single-cycle time-series data is detected, wherein the added-value creating portion creates an added-value in the predetermined process, and the unproductive portion does not produce any added-value in the predetermined process;
• and
• computing an amount of energy consumed in the unproductive portion as the amount of energy to be reduced, wherein
• the detecting of the single-cycle time-series data extracts waveform feature data from the acquired time-series data, performs pattern matching between the waveform feature data and the waveform model information stored in the memory, and detects the single-cycle time-series data in which the waveform feature data matches the waveform model information.
