Problems solved by technology

Such a device may indeed have the effect of preventing falls, but due to its bulkiness and complexity, it is redundant for most elderly people who can take care of themselves, and it consumes high energy and is expensive
[0006] In view of the above situation, the inventor believes that although there are many existing inventions, they cannot meet the actual needs of the vast number of elderly people.

Abstract

The invention provides a human body unbalance detection method and device, and a fall prevention device and method. The human body unbalance detection method comprises a gravity center acceleration sensor, a left foot acceleration sensor, a right foot acceleration sensor and a main control unit, wherein the gravity center acceleration sensor detects the longitudinal acceleration, lateral acceleration and vertical acceleration of a body weight center when a human body walks; the left foot acceleration sensor detects the longitudinal acceleration and lateral acceleration of a left foot when the human body walks; the right foot acceleration sensor detects the longitudinal acceleration and lateral acceleration of the right foot when the human body walks; the main control unit judges whether the human body is unbalanced through the deviation between the detected longitudinal accelerations and lateral accelerations of the left and right feet and the longitudinal acceleration and lateral acceleration of the body weight center or the deviation between the detected lateral displacements and longitudinal displacements of the left and right feet and the lateral displacement and longitudinal displacement of the body weight center when the vertical acceleration of the body weight center is smaller than a vertical acceleration threshold value of the gravity center or the vertical displacement of the gravity center is smaller than the vertical displacement threshold value of the gravity center, and outputting alarm signals if the human body is unbalanced.

Description

technical field [0001] The invention relates to human body imbalance detection and alarm technology during walking, in particular to a human body imbalance detection device and method, and a fall prevention device and method. Background technique [0002] Global aging is an increasingly serious problem today. According to reports, by 2020, 13 countries in the world will become "super-aged" countries, that is, more than 20% of the population is over 65 years old. And by 2030, the number of "super-aged" countries will rise to 34, and by then, China will also become the country with the highest aging population in the world. [0003] The physical function of the elderly declines, the sense of balance decreases, and they are prone to falls in daily life. The morbidity rate, high hospitalization rate, and high mortality rate of falling in the elderly not only cause pain to the body and mind of the elderly, but also bring a heavy burden to the family and society. Elderly falls a...
