Abstract

The invention relates to the technical field of riding state detection, and discloses a rider motion state detection method, which comprises the following steps of obtaining reflected waves received after radar waves with different frequencies are transmitted to different body parts of a rider; acquiring motion state parameters corresponding to different body parts of a rider while acquiring the reflected waves; performing wavelet transformation on all the reflected waves to obtain waveform characteristic parameters of all the reflected waves; training a BP neural network by taking the waveform characteristic parameters of the reflected waves as input sample data and taking motion state parameters corresponding to the reflected waves as output sample data to obtain a motion state detectionmodel; and detecting the motion state of the rider in the riding process through the motion state detection model. The method and the device have the technical effect of uniformly detecting various motion states.

Description

technical field [0001] The invention relates to the technical field of riding state detection, in particular to a method, device, stopwatch and computer storage medium for detecting a rider's motion state. Background technique [0002] Cycling is an endurance sport with aerobic endurance as the core. During cycling, the electrolyte fluid of the human body is fast and consumes a lot of physical energy. It is often necessary to inject energy and food in a timely manner to replenish what is needed in time. This requires cyclists to make accurate judgments on their own physical conditions in a timely manner. However, cyclists generally focus on riding, and inevitably neglect to pay attention to their own physical conditions. This requires the help of automated detection methods during riding. Keep abreast of your own physical condition by cycling. [0003] At present, the detection of exercise status generally adopts single-function detection instruments, such as heart rate mon...
