Embodiment Construction

[0055] The present invention will be further described below in conjunction with specific examples.

[0056] Such as figure 1As shown, the elderly fall detection method based on the attractor propagation algorithm described in this embodiment includes the following steps:

[0057] 1) collect the sample information of each sensor;

[0058] 2) Processing and normalizing the sample information, and constructing a weighted sum of sample states;

[0059] 3) Weighting and inputting the samples into the AP clusterer;

[0060] 4) Utilize the clustering results to construct a balanced binary tree, and mark the clustering results;

[0061] 5) collect the information of each sensor;

[0062] 6) Process sensor information and perform normalization, and construct state weighted sum;

[0063] 7) Find the balanced binary tree according to the weighted sum result, and output the prediction result.

[0064] The sensors in steps 1) and 5) include a three-axis acceleration sensor (when the...

Abstract

The invention discloses a method for old man falling-down detection based on an attractor propagation algorithm. The method comprises a step 1) of collecting sample information of each sensor; a step 2) of processing the sample information and performing normalization, and constructing a sample state weighted sum; a step 3) of inputting the sample state weighted sum into an AP cluster; a step 4) of utilizing clustering results to construct a balanced binary tree, and marking the clustering results; a step 5) of collecting information of each sensor; a step 6) of processing the sensor information and performing normalization, and constructing a state weighted sum; a step 7) of searching the balanced binary tree according to a weighted sum result, and outputting a predicted result. According to the method, through the AP cluster implemented through the attractor propagation algorithm and the balanced binary tree constructed through the state weighted sum, the old man falling-down detection accuracy rate is effectively improved, and thus the problem that an existing falling-down detection method is not high in accuracy rate and large misjudgment occurs is solved.

Description

technical field [0001] The invention relates to the technical fields of medical health and machine learning, in particular to an elderly fall detection method based on an attractor propagation algorithm. Background technique [0002] The age structure of our society is gradually aging, and the safety guardianship of the elderly is getting more and more attention. Among them, falls are the first cause of injury to the elderly over 65 years old in my country, which seriously affects the quality of life and physical and mental health of the elderly. The death cause monitoring data of the National Disease Surveillance System in 2006 showed that the fall mortality rate of the elderly over 65 years old in my country was 49.56 / 100,000 for men and 52.80 / 100,000 for women. The death rate from falls in the elderly increases sharply with age. Therefore, how to detect the occurrence of the elderly's fall time at the first time, so that the elderly can obtain medical treatment in time ...
