摘要：为了可靠获取人体步态信息,实现对外骨骼机器人控制提供重要参数,研究了一种基于IMU与Wi Fi技术的步态监测系统。阐述了监测系统的软、硬件结构和该监测系统的实际应用。该步态监测系统包括多个安装于肢体的无线传感节点、汇聚节点与上位机监测平台。无线传感节点获取各节点倾角传感器信息,并通过Wi Fi无线网络传输到上位机监测平台。经实测该监测系统在空旷地带的监测范围是80m,充满电状态下可以连续30h输出角度信息,满足人机系统动态位姿信息监测的要求。
In order to obtain the human real-time gait information and provide important parameters for the control of exoskeleton robot, a gait signal acquisition system is designed in this paper based on IMU and WiFi technology. The hardware, software and the practical application of the monitoring system are introduced. The system includes a plurality of wireless sensor nodes installed in the body, sink node and PC monitoring platform. Wireless sensor nodes acquire the information of each motion sensor, and then transmit to the monitoring system in host computer through the WiFi network. The system can cover a monitoring range of 80 meters in open area, and has up to 30 hours of battery life under full power condition, which can meet the monitoring requirements of dynamic position and attitude information.
