摘要
提出了一种新颖的脚部加速度信息获取方法,并利用嵌入式低功耗技术和无线数据传输技术,成功研制了一套试验系统。试验结果表明,本系统具有较高的数据采样速率和良好的无线数据传输性能,能实现脚部三维加速度信息的精确获取。本系统为进行基于脚部加速度信息的相关研究提供了重要的试验平台,具有重要的基础意义。
The paper introduces a novel data acquisition system. Based on the low-power technology of embedded system, we designed an acquisition system based on wireless data transmissiorL The results show that the system can sample in a high speed, with high quality in wireless data transmission, and can achieve the goal of accurate data acquisition of foot acceleration information. The system provides an important approach for the study basing on foot acceleration information.
