A rapid fall detection system and method based on multi-sensor combination

Abstract

The present invention relates to a multi-sensor combination-based fast tumble detection system. The system comprises a human body acceleration detection unit (104), a foot bottom pressure detection unit (105), a computing unit (101), a remote communication unit (102), a positioning unit (103), an interactive operation unit (106), a local alarm unit (107) and a main control unit (108); the human body acceleration detection unit (104) acquires an acceleration value during the movement process of a human body; the foot bottom pressure detection unit (105) detects the pressure value of the foot bottom of the human body; the computing unit (101) processes and judges the data acquired by the detection unit; the remote communication unit (102) realizes remote communication; the positioning unit (103) obtains location information and provides a positioning function; the interactive operation unit (106) provides a one-key help seeking function and a personalized man-machine interaction function; and the main control unit (107) controls the units and works in cooperation with the units. Compared with the prior art, the multi-sensor combination-based fast tumble detection system of the invention obtains more comprehensive and high-reliability information based on the body acceleration signals and foot bottom pressure signals. The interactive operation unit has the man-machine interaction function, and therefore, false alarm behaviors can be prevented, and autonomous help seeking can be performed.

Description

technical field [0001] The invention relates to a fall detection method, in particular to a rapid fall detection system and method based on multi-sensor combination. Background technique [0002] With the development of economy, science and technology, the rapid progress of medical level, and the improvement of people's living standards, the whole world is facing a serious problem, that is, the problem of population aging. The problem of population aging has been particularly prominent in China in recent years. According to the United Nations' statement on population structure, when the proportion of elderly people aged 60 and 65 in a society exceeds 10% and 7% of the total population, it means that the society is in a state of insufficiency. aging society. According to the latest census released by my country, the proportion of the population over 60 years old in my country is 13.31%, of which the population aged 65 and over accounts for 8.91%. According to the definition...

Problems solved by technology

[0005] According to a large amount of data, falling itself does not directly endanger life, but more often, after the fall behavior, the elderly panic and cause sudden symptoms such as heart disease or high blood pressure, or the fall itself is caused by some sudden symptoms. Due to the occurrence of diseases, the best time for rescue is missed because of failure to get rescue in time, resulting in serious consequences

However, as analyzed above, more and more "empty-nester elderly" and certain social problems in today's society make it difficult for the elderly to receive timely assistance after a fall
