Abstract

The invention provides a human body fall detection method, device and system. The human body fall detection method comprises the following steps: obtaining an infrared detection result of each infrared sensor in an infrared detector group, wherein each infrared sensor in the infrared detector group is used for carrying out infrared detection on a corresponding coverage area higher than a preset horizontal height, coverage areas of adjacent infrared sensors being connected with each other to form a detection area of the infrared detector group, the infrared detector group being arranged in a user passing area, the passing direction of the user passing area being the direction where a user passes the coverage areas of the infrared sensors in the infrared detector group in sequence; according to the infrared detection results, determining a leaving user disappeared from the detection area, and determining the last infrared sensor, which lastly detects the leaving user; and by judging whether the last infrared sensor, which lastly detects the leaving user, is the first or the last infrared sensor in the infrared detector group, judging whether the leaving user falls over.

Description

technical field [0001] The invention relates to the technical field of human body fall detection, in particular to a human body fall detection method, device and system. Background technique [0002] With the acceleration of population aging, the population of the elderly is particularly large, and the physical function of the elderly declines. Environmental factors and self-factors increase the risk of falls. , Any chronic disease that can lead to unstable gait, balance dysfunction, dizziness, vision and disturbance of consciousness in the elderly can be prone to falls; the elderly are a high-risk group for falls. Due to their weak physical function and reduced balance ability, Falls, which ordinary people don't care much about, may cause disability or even death to the elderly. Especially for the empty-nesters, whose children are not around, after an accidental fall at home, there is a high possibility that no one will help after the danger occurs. Therefore, how to quick...
