摘要
针对居家训练的运动效果问题,设计了一款基于FPGA的运动训练辅助系统。在系统硬件部分,基于FPGA搭建了以动作采集与控制模块、数据中转模块与机械臂为主的三个主要模块,并通过PID控制算法,保证运动训练机械运作的稳定。在系统功能部分,基于DTW算法对动作标准度进行判断。实验测试证明,当P、I、D参数分别优选为1.2、0.2、0.5时,系统机械部分可以及时平稳达到目标位置,动作转变平滑;系统功能的部分均展示成功,动作标准度分析符合实际运动情况。整体而言,测试结果符合预期设计,证明设计的运动辅助系统可以被用于居家运动的训练指导。
Aiming at the problem of sports effect of home training,a sports training auxiliary system is designed based on FPGA.In the hardware part of the system,three main modules including motion acquisition and control module,data transfer module and robot arm are built based on FPGA,and PID control algorithm is adopted to ensure stable mechanical operation.In the system function part,this paper designs the judgment of action standard degree based on DTW algorithm.Experimental tests show that when P,I and D parameters are selected as 1.2,0.2 and 0.5 respectively,the mechanical part of the system can reach the target position in time and smoothly.All the parts of the system function are displayed successfully,and the movement standard degree analysis is consistent with the actual movement situation.On the whole,the test results are consistent with the expected design,which proves that the motion assistance system designed in this paper can be used for home exercise training guidance.
