Falling-preventing protection system

Abstract

The invention provides a falling-preventing protection system. According to the falling-preventing protection system, the falling state and the falling direction are prejudged together by utilizing the sole pressure and an attitude sensor, after a user is determined to be in a falling process, a corresponding air bag is inflated. The to-be-inflated air bag comprises a main inflating pipeline, an auxiliary inflating pipeline and the rest part of the air bag; the air pressure and the inflating speed of the main inflating pipeline are guaranteed with priority, so that the main stressing support is realized; in order to improve the inflating speed, a plurality of small high-pressure air bottles are adopted to inflate one air bag, and the starting of the inflating process is controlled by an electromagnetic inflation valve. On the aspect of the inflating sequence, the whole space is not subjected to the uniform inflating, but the inflating passages with different levels are divided in the air bag, firstly, the important channel space is inflated, then the secondary channel space is inflated, and finally the rest part of the air bag is inflated, namely, the key part is firstly protected, then the other parts are protected, and thus the adverse effects which are possibly generated by the insufficient inflating speed are reduced.

Description

technical field [0001] The patent of the present invention belongs to the field of portable electronic anti-fall protection system, and specifically relates to an anti-fall protection system that protects people when they fall while walking. Background technique [0002] Falls are the second leading cause of accidental injury death in the world, and how to prevent falls has become the key to protecting the lives of the elderly. The prior art mainly realizes the fall alarm function, which only realizes the alarm function after the human body falls. At the same time, there are also a few studies trying to realize the prediction of falls and the prediction of falling posture through multi-modal sensors including three-axis accelerometers, three-axis gyroscopes, and three-axis magnetometers. This patent will use the plantar pressure sensor and attitude sensor to predict the fall, starting from the essence of the fall, that is, the state of the feet off the ground, the rotatio...

AI Technical Summary

Problems solved by technology

The inflation system of the lifejacket generally adopts manual control and automatic control after encountering water. A single bottle is used to inflate the lifejacket. In order to ensure the buoyancy and inflation space is large, the inflation speed is less than 5 seconds, and the inflation time for the protection against falling is too long.
