Human body tumbling automatic detecting and alarming device and information processing method thereof

Abstract

The invention relates to a human body tumbling automatic detecting and alarming device and an information processing method thereof. The human body tumbling automatic detecting and alarming device comprises a moving device and a long-distance alarm processing terminal, wherein the moving device comprises a central information processor, the input end of the central information processor is electrically connected with a triaxial acceleration transducer by an A / D converter; three-dimensional acceleration information of upper trunks of a user are collected and are fused, and the impact of the human body and upper trunk inclination angle before and after the impact are integrated to judge whether the human body tumbles; when the impact which is used for judging a tumbling level is generated, the acceleration which is greater than or equal to a threshold value of 3.5g is used as a standard; and if the user tumbles or needs help, the tumbling information is transmitted to the long-distance alarm processing terminal. The human body tumbling automatic detecting and alarming device has the characteristics of high detection rate and low misjudge rate for human body tumbling detection, has effect on detecting multiple-impact type tumbling and rolling type tumbling and can be used for rescue operations after the bumble of old people, patients, danger operating personnel, and the like.

Description

Technical field: [0001] The invention relates to the monitoring and identification of human movement behaviors and states, a detection method, an alarm system and an information processing method thereof, in particular to a device for automatically detecting and alarming human body falls and an information processing method thereof. Background technique: [0002] The problem of falls in the elderly has prominent characteristics such as high incidence rate, high hospitalization rate, and high mortality rate, which has attracted extensive attention of many scholars. According to the statistics of the World Organization for Disease Control and Prevention, one-third of the elderly over 65 years old in the world will fall every year, half of which are recurrent falls, and the rate of falls increases with age; the elderly who fall Moderate and severe injuries (hip fractures and head trauma) occur in 20%-30% of people, and 60% of them are limited or unable to move, resulting in hug...
