Abstract: The BeiDou Navigation Satellite System(BDS) independently researched and developed in China has gradually matured and is widely used in the civilian field. There are still many shortcomings in football training in China. Improper football training not only causes poor training effect, but also may does harm to the athlete's body. In view of the above problems, this paper designs a soccer training system based on Beidou smart bracelet. Blending BDS, multi-sensor fusion technology, Internet technology, 3D video technology and wireless communication technology, the smart bracelet has high-precision real-time positioning, blood pressure measurement, heart rate detection, speed and acceleration measurement, motion recognition, onebutton alarm and track record and other functions to improve the scientific, safety and pertinence of training.
