Acquisition System Design of Human Lower Limbs Motion Information
In order to get the information close to the regulation of movement of the human lower limbs, a multichannel information acquisition project is put forward for the human lower limbs joints motion. This project can achieve a higher compatibility, more appropriate human body motion rules for lower limbs rehabilitation robots design and research. Based on the technologies of FPGA, USB2.0 interface and LabVIEW, a set of human lower limbs motion information acquisition system is designed with characteristics of high performance, low power consumption, multichannel and easy extension. The experiments show that the system can achieve multichannel synchronous information acquisition and processing, data real-time display and storage. It provides an experimental platform which can analyze and process data steadily and can obtain basic data that nestle human motion state.
