摘要
提出了一种有效监测人体坐姿压力的系统,设计了柔性触觉传感器阵列,基于多路模拟开关CD4051、微处理器MSP430与无线发送模块实现数据的采集与传输,在上位机软件中通过低通滤波、配色与插值算法,并应用分布式压缩感知理论,形成了模拟人体坐姿压力分布的彩色图像,图像真实清晰,便于观察。实验结果表明:系统稳定性和分辨率较好,且能够实现坐姿压力分布的实时测量和显示。
An effective monitoring system of body sitting posture pressure is proposed. A flexible tactile sensor array is designed,a multi-channel analog switch CD4051,microprocessor MSP430 G2553 and wireless transmission module for data acquisition and transmission. Through low-pass filtering,color matching and interpolation algorithm in upper PC software,distributed compressed sensing theory is applied,color images which simulates human body＇s sitting posture pressure distribution is formed,the image is ture,clear and convenient for observation.Experimental results indicate that the system has good stability and resolution,and real-time measurement and display of sitting posture pressure distribution can be achieved conveniently.
