Abstract

The present invention provides a human body movement state monitoring method and device. The method comprises the following steps performed repeatedly: obtaining acceleration signals having a set sampling time period from output of a triaxial acceleration sensor worn on a human body, and calculating the energy and average power of the acceleration signals; determining a human body movement state according to the average power of the acceleration signals, and if the average power of the acceleration signals is more than a predetermined fierce movement threshold, determining that the human body is in a fierce movement state, if the average power of the acceleration signals is less than a predetermined sleeping threshold, determining that the human body is in a sleeping state, if the average power of the acceleration signals is less than the fierce movement threshold and is more than the sleeping threshold, determining that the human body is in a light movement state; if the human body is in the fierce movement state, further determining whether the acceleration signals have quasi-periodicity, if the acceleration signals do not have quasi-periodicity, determining that the human body is in an irregular fierce movement state, if the acceleration signals have quasi-periodicity, determining that the human body is in a regular fierce movement state. The method can automatically, comprehensively, round-the-clock, accurately monitor various movement states of a person.
