内嵌状态机的MEMS传感器及其在体位监测中的应用研究
Study on a MEMS sensor with embedded state machines and its application in body position detecting
摘要
Abstract
Aiming at the need of rapid recognition of human body motion of medical monitoring assistance devices , a body position and motion recognition system is designed .The system consists of a MEMS sensor LIS 3DSH with two em-bedded state machines and a SOC chip nRF 51822 which can realize the Bluetooth 4 .0 protocol .On the basis of re-alizing the functions of the LIS3DSH's embedded modules such as vector filter , the method for design of its two embedded state machines is studied emphatically and illustrated by two experiments .The experiments validates the feasibility and effectiveness of the body position transition and fall recognition .Because of the sensor's embedded state machines and the Bluetooth SOC , the design brings the advantages of portable , fast, and Bluetooth 4.0 wire-less network transmission .This study can contribute to the human stumble protection devices , and can also be used for multi-sensor fusion based on Bluetooth 4.0 wireless networks .关键词
