Abstract

The invention discloses a wearable falling prediction protection system and a prediction method thereof. The system comprises a hooded protective clothing body composed of a lining and a jacket, a folding airbag is arranged between the lining and the jacket, and a head sensor is arranged in a cap at the upper end of the hooded protective clothing body. A control module, a gas generator and a powermodule are arranged at the waist position at the lower end of the hooded protective clothing body. The control module includes a central processing unit and a waist sensor. The head sensor, the waistsensor, the gas generator and the power module are connected to the central processing unit through wires, and the gas generator is connected to the folding airbag. The system has the advantage thata six-axis inertial sensor is adopted to perform angle data acquisition and joint analysis on the waist and the head of a human body to achieve earlier prediction of falling; a falling prediction algorithm based on a head and waist angle correlation coefficient threshold, a waist angle threshold and a waist angular speed threshold is adopted, the prediction accuracy is improved, and the falling can be predicted early.

Description

technical field [0001] The invention relates to the technical field related to biomedical engineering, in particular to a wearable fall prediction and protection system and a prediction method thereof. Background technique [0002] According to the latest standards of the United Nations, an aging society refers to a region where the population aged 65 and over accounts for 7% or more of the total population, and the region is deemed to have entered an aging society. According to the 2003 China Statistical Yearbook, a sample survey was conducted on 1% of the population in 2002, and it was found that the elderly population aged 65 and above had accounted for 8.16% of the total surveyed population, indicating that China has entered an aging society. With the increase of the elderly population, social pension issues and the physical and mental health of the elderly have received more and more attention, and falls are a common cause of morbidity and death in the elderly, and more...
