Low-power-consumption realization method for early warning device for fall prevention

Abstract

The invention provides a low-power-consumption realization method for an early warning device for fall prevention. On the basis of motion interruption information provided by a motion sensor and a low-power-consumption characteristic of a shutdown mode of a single-chip microcomputer, the single-chip microcomputer detects a motion interruption signal provided by the motion sensor and then the working states of the single-chip microcomputer and the motion sensor can be adjusted flexibly, thereby achieving an objective of overall power consumption reduction. Meanwhile, the motion sensor carries out accelerated speed acquisition only at a low sampling rate in a low-power-consumption mode; and once the accelerated speed is detected to exceed a set threshold value, a motion interruption signal is generated immediately and the single-chip microcomputer is informed of state changing of a monitored object from a static stat to a moving state; and the single-chip microcomputer updates configuration of the motion sensor, so that the motion sensor works in a high-speed sampling state.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for realizing low power consumption of an anti-fall warning device. Background technique [0002] Studies have shown that among the elderly over 65 years old, the proportion of more than one fall experience per year is as high as 1 / 3, and 20% to 30% of them will cause abrasions, hip fractures, and head injuries during falls. etc.; and with increasing age, the risk of falling increases. The fall itself may cause harm to the human body, and if timely assistance cannot be obtained after the fall, the result may be worsened. How to effectively detect falls and provide timely help information is extremely important; if timely warnings can be made before a fall, many tragedies can be avoided; It can greatly reduce the safety threat to the elderly caused by falls. [0003] At present, the solution to realize the fall warning is mainly to realize the real-time monitoring of ...
