Monitoring identification method for swimming information based on wearable intelligent device

Abstract

The invention discloses a monitoring identification method for swimming information based on a wearable intelligent device. The method comprises the following steps: A) collecting standard data of swimming, thereby acquiring signal feature diagrams of various swimming strokes; B) selecting acceleration magnitudes of y axis and z axis for distinguishing the swimming strokes; C) filtering fault motions, setting a threshold value, removing fault motion interference, confirming the data as being valid if the value exceeds the threshold value, and then performing low-pass filtering and feature extraction identification operation; and D) designing a filter, performing low-pass filtering and filtering high-frequency noise and harmonic wave, thereby acquiring a swimming base frequency signal. After the method is adopted, a swimming index is acquired through statistic analysis; the monitoring method is reasonable, the calculated amount is low and the occupied memory space is less; the swimming stroke and swimming related parameters (arm pulling times, swimming distance, swimming time, swimming speed, and the like) can be accurately confirmed and identified; the monitoring identification data are accurate; and the method has higher practicability for the embedded wearable intelligent device.
