Title:
CURRENT WAVEFORM FLUCTUATION STARTING POINT IDENTIFICATION METHOD, ELECTRONIC DEVICE AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/036483
Kind Code:
A1
Abstract:
Provided are a current waveform fluctuation starting point identification method and the corresponding electronic device, the method comprises the following steps: identifying and extracting a fluctuation section waveform and a stationary section waveform close to the front end of the fluctuation section waveform in the total current waveform (12); counting a mean value of each data point in the stationary section wave, a difference value A between each data point and the mean value, and a difference value B between two adjacent data points, calculating an average fluctuation limit value according to the difference value A, and calculating an adjacent fluctuation limit value according to the difference value B (13); sequentially searching and calculating a difference value C between each data point and the mean value from the front end of the fluctuation section waveform until the difference value C exceeds the average fluctuation limit value, and calling the current data point as a first data point (14); reversely searching and calculating a difference value D between each data point and the previous data point from the first data point along the fluctuation section waveform until the difference value D does not exceed the adjacent fluctuation limit value, and marking the current data point as a fluctuation starting point (15). The method can accurately recognize the position of the fluctuation starting point, and the recognition speed is high.
