[0029] The specific embodiments of the present invention will be further described below in conjunction with the drawings:
[0030] Reference figure 1 , A fall detection and early warning method based on smart wearable devices, including the following steps:
[0031] A. Read in training data, the training data includes multiple sets of healthy people's gait data and multiple sets of abnormal gait data, and the training data is the acceleration of the hand swing during walking;
[0032] First of all, the acceleration data of the hand swing can accurately reflect the state of the hand swing under the state of uniform motion. figure 2 The ideal model of healthy human gait data shown, when the time is 0, the acceleration is the maximum, the arm swings forward from the end, the arm swings the maximum speed when the first zero point is reached, and then starts to decelerate until the arm swings to the foremost position. The first half cycle of a gait; then the second half cycle of a gait ...
