摘　　要：针对目前跑步机锻炼模式单调、乏味的问题,结合视频播放设备设计了一套跑步机3D视频同步播放控制系统。采用磁场传感器采集跑步机转轴状态,通过单片机实时计算跑步机速度,并进行滤波以后送给上位机。编写上位机控制软件,利用Windows键盘相关的API函数控制播放器速度,使视频播放速度随着跑步者速度变化而同步改变,实现了体验者与视频播放的互动,增强了跑步运动的趣味性。实验结果表明,设计方案有效可行,且实用性强,可广泛地应用到其他健身器械中。A 3D Video synchronous broadcasting system for the treadmill is designed in view of the monotonicity and insipidity of the traditional treadmill. The speed of treadmill is measured by the magnetic sensor and the single chip machine and then it is transmitted to the PC software after filtering. PC software,controlling the speed of 3 dimension（3 D） player,is compiled by using the Windows Application Programming Interface（API） function related to the keyboard. The speed of 3 D video player is synchronized with the speed of the treadmill. It realizes the interaction between experiencer and the 3D player,and it increases the enjoyment. The results show the efficiency,feasibility and practicability of the design. The technique also can be widely applied in other fitness equipments.
