Embodiment Construction
[0033] Below in conjunction with embodiment the present invention is described in further detail.
[0034] A kind of human fall detection method based on triaxial acceleration proposed by the present invention, it specifically comprises the following steps:
[0035] ① Using a three-axis acceleration sensor worn on the upper body of the human body, the three-axis acceleration data of the human body is collected in real time according to the set collection frequency, and the collected X-axis acceleration values, Y-axis acceleration values, and Z-axis acceleration values of the human body are correspondingly recorded as A x 、A y and A z , then according to A x 、A y and A z , calculate the acceleration value of the human body, denoted as A, A = A x 2 + A y 2 + ...
