摘要：为研究康复型下肢外骨骼的运动状态,基于微机电系统(microelectromechanical system,MEMS)倾角传感器和薄膜压力传感器建立人体运动状态监测装置。该装置按照功能划分为传感器模块、无线发送模块和数据处理模块,传感器模块利用倾角传感器和薄膜压力传感器感知肢体运动倾角和脚底支反力,无线收发模块通过Zig Bee将数据发送至计算机,数据处理模块采用Labwindows/CVI软件实现步态周期归一化处理。通过该系统与某型步态图像识别系统同步进行多种步速的步态试验,得到不同步速下两装置膝关节运动倾角归一化数据对比曲线,其结果基本一致,试验表明本监测装置具有实用性。
In order to study the movement state of the rehabilitative lower limb exoskeleton,a monitoring device based on the microelectromechanical system tilt sensor and thin film pressure sensor was established.The device had its function divided into sensor modulewireless send module and data-processing module.The sensor module used the tilt sensors and the film pressure sensor to perceive the movement angle of the limb and the reacting force of the foot.The experimental data was send to computer with ZigBee.The data-processing module used the Labwindows/CVI to achieve the period normalization of the gait.The system synchronized with a certain gait recognition system carried out tests under a variety of gait speed,and the data comparison normalization curves of knee joint motion angle of the two systems was obtained.The results of the gait test data of the system were basically the same as that of a gait image recognition system.It is proved that the monitoring system is practicable.
