A Fall Event Detection System Based on Shuangjian

Abstract

The invention provides a falling accident detecting system based on dual technologies. The falling accident detecting system comprises a front end detecting system and a central processing system. The front end detecting system comprises two or more dual-technology detectors. Detection on human bodies in different space areas can be realized through arrangement of detector locations. The central processing system mixes and analyzes information according to information detected by the front end detecting system, judges various kinds of information that the human bodies pass through detecting areas, stay or fall down according to a falling accident judging method, and sends warning according to confirmed falling accidents. Low-cost dual-technology detectors are adopted, and the system has high precision on falling accident detection through reasonable arrangement. The falling accident detecting system has the advantages of non-intrusive detection, low production cost, low mistaken warning rate or false warning rate and the like, and is suitable for automatic detection of falling accidents of old people living alone and with home-based care.

Description

technical field [0001] The present invention relates to an intelligent detection system, specifically, a double-detection-based fall event detection system, that is, to automatically detect fall events of the elderly by using microwave and infrared double-detection technologies. Background technique [0002] The fall event detection system based on Shuangjian is a system based on Shuangjian detectors to detect falls of the elderly. With the intensification of population aging, the problem of providing for the elderly living alone has become a major social problem. Due to age, the elderly living alone have a decline in their physiological functions. Once they encounter accidents such as illness or falls, they often lead to disastrous consequences because no one knows and it is difficult for them to save themselves. Therefore, the safety and health monitoring faced by the elderly in solitary situations has become an increasingly important social issue. The main goal of this ...

AI Technical Summary

Problems solved by technology

This system has the characteristics of high detection rate and low misjudgment rate, but it requires the elderly to wear these complex devices strictly according to the requirements, which greatly affects the daily life of the elderly.

[0006] 2. At present, the cost of most fall detection patents is relatively high, such as Chinese patent application number: 201110298650.5, patent name: portable wireless fall monitoring system based on walking power generation

This system includes: an energy collection and storage module, used to collect and store electrical energy through walking; an acceleration sensor, used to collect three-dimensional acceleration information of the limbs; a central processing unit, used to receive the information input by the acceleration sensor, and judge whether the human body is Falling down; this system uses human body energy to generate electricity, and the system integration is high in power consumption, but the cost of the equipment itself is relatively high
