Embodiment Construction

[0018] The method for monitoring and identifying swimming information based on a wearable smart device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the swimming information monitoring and identification method based on the wearable smart device of the present invention must include a six-axis sensor, and the six-axis sensor includes a three-axis acceleration and a three-axis gyroscope. Through the configuration conversion of the drive, a three-dimensional Space X-axis, Y-axis, Z-axis, the acceleration values ​​in three directions and the angular acceleration around each axis. Through the configuration drive, the six-axis sensor can store a certain length of acceleration value and angular acceleration value in the cache FIFO (First-InFirst -Out), when the data length reaches the FIFO length, an interrupt can be generated, and the required value can be re...

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.

Description

technical field [0001] The invention relates to a wearable smart device suitable for wrist wear, in particular to a swimming information monitoring and identification method based on the wearable smart device. Background technique [0002] Swimming, as a sport that can effectively enhance various functions of the human body, is favored by all kinds of people. With the rise of smart wearable devices, there are more and more devices that can recognize and guide swimming strokes. At present, Garmin, as a professional sports monitoring device, is also loved by professional athletes on the market. However, due to its monitoring method design Unreasonable, making its accuracy still need to be optimized. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a swimming information monitoring and recognition method based on a wearable smart device that can improve recognition accuracy. [0004] In order to solve the above tec...
