Design and Fabrication of Intelligent Training Javelin Based on Embedded Technique

The angle of throwing and the speed of throwing are very important technical indicators in the javelin throwing training process. It is helpful to improve the effect of training according to the feedback information in real time for each training session. In view of this situation, based on the embedded technique, we designed and produced the javelin-throwing posture measuring system. A new intelligent training javelin with an embedded moving posture measurement system was manufactured through further mechanical design and processing. This intelligent javelin can realize the real-time inspection and transmission of key javelin-throwing parameters and quantitatively describe the regular moving pattern of a javelin thrower. Coaches and athletes may analyze the training results according to the parameters they get from our system, which realize quantification and modification of javelin training and provide technical support to the improvement of the athletic level of javelin throw.
