MEMS在运动轨迹显示中的应用

为便于通过运动轨迹分析研究物体运动特征，设计了一个运动轨迹测量显示装置，利用微机电系统（micro‐electronic mechanical system ，MEMS）技术与可视化设计，以Freescale Semiconductor公司生产的三轴低重力加速度传感器MMA8450Q和计算机为核心搭建硬件平台，以NI（National Instruments）公司开发的 LabWindows／CVI 8．5为平台编写具有可视化虚拟操作界面的控制程序，并通过性能验证实验，完成了基于 M EM S技术的运动轨迹测量显示装置的设计、实现、调试与实验过程。

Application of MEMS in motion trajectory display

In order to make it convenient to study motion features by motion trajectory analysis, this paper designed a motion trajectory measurement and display device, where MEMS (Micro Electronic Mechanical System) technology and visualization technology were put into use. MMA8450Q, a 3 axis, low g acceleration sensor of Freescale Semiconductor Corporation, and a computer played the core role of hardware development platform, while LabWindows/CVI 8.5, developed by National Instruments (NI) Corporation, was used in visual programming. After series of performance validation experiments, the procedure of designing, complement, debugging and experiments of the motion trajectory measurement and display device based on MEMS was accomplished.
