[background technology]
Falling refers to that happen suddenly, involuntary, unintentional Body Position Change, for example fall on the ground or lower plane on.According to statistics, have every year in the world about 424000 examples dead directly related with the behavior of falling, falling is the second largest reason (being only second to traffic hazard) that causes in the world Accidents death.Studies show that, in the elderly of over-65s, have every year 1 time or repeatedly fall the experience ratio up to 1/3, wherein the old man of 20-30% can cause scratch, Hip Fracture, head injury etc. in the event of falling, and increases along with the increase at age.In the U.S., the annual medical total expenses that is used for falling is above 20,000,000,000 dollars.China 1.3 hundred million the elderlys that have an appointment at present have 2,000 ten thousand the elderlys that altogether 2,500 ten thousand accidents of falling occur at least every year approximately, and direct medical cost is above 5,000,000,000 yuans.This shows that falling becomes the key factor that threatens the elderly's life security and increase burden on society.
Judge to fall at present and mainly contain following 3 kinds of methods:
(1) based on the analysis of video image: the real time kinematics of object is monitored by camera, and its weak point is to guarantee user's personal secrets;
(2) based on the analysis of audio signal: the event of falling is impacted the frequency that causes vibrating and is partly judged by analyzing, but it installs more complicated, and fund input is also larger;
(3) detect based on the device of Wearable: consider user's the right of privacy and reduce disturbance user life style as far as possible, the device of Wearable is best suited for.But the fall detection of Wearable/monitoring and warning device generally all are based on the inertia sensing unit.The single three axis accelerometer of the at present general employing of the sensing module of common " alarm of falling ", measuring accuracy and data mode are limited, or the thresholding algorithm that adopts is good not, therefore only can realize the warning function after human body is fallen and early warning before can not realizing falling, and not take effective intervening measure when human body is fallen tendency monitoring.
There is following defective in above-mentioned prior art:
(1) all unrealized front early warning of falling: present common " alarm of falling ", the single three axis accelerometer of the general employing of its sensing module, measuring accuracy and data mode are limited, or the thresholding algorithm that adopts is good not, therefore only can realize the warning function after human body is fallen and the front early warning that can not realize falling, thereby unlikely realize instant anti-intervening measure and the real-time protection of falling;
(2) all unrealized front effective interventions of falling: as previously mentioned, since the common alarm of falling can not be realized accurate early warning at present, thereby unlikely realize the instant anti-intervening measure of falling;
(3) accuracy of falling is judged undesirable: the present judgment means of falling mainly is only to rely on acceleration to judge the generation of the event of falling mostly, but the motion of human body schedule is very complicated, and the accident behavior (1-2 second) of falling and normally occuring in a flash, rely on less or single human motion attitude information to predict that the reliability of falling is not high, when fall tendency and when failing in time to judge of human body, just do not have the early warning effect, do not fall tendency and make erroneous judgement when disconnected when human body, must make troubles to wearer.
