The Digitizing The Discus Hardware Circuit System Research

With the development of competitive sports, sports research plays more and more important role for Athletes to improve performance. For discus project, two-dimensional photography and three-dimensional platform for force measurement has been widely used to reveal the law of body to discus. Two-dimensional photography and three-dimensional platform for force measurement does not clearly reveal the dynamic process which the hand make effect to the discus, and this is the most concerned for physical education, coaches and athletes. For discus throwing project, there is no ideal measuring equipment. The pros and cons of the discus throwing are closely related to the force and angle of discus throwing. We can approximately get the posture and force of discus at the moment of just leaves hand, which can be based on to study the whole process of discus throwing in-depth. At present there are no such instruments for measuring at home and abroad.The hardware circuit system of digital discus is studied in this paper. The discus structure built-in circuit board was designed according to the discus international standards. Digital discus was developed based on acceleration sensors and angular velocity sensor. The digital discus can obtain3D acceleration and3D angular velocity information of the discus in the process of discus athletes throwing the discus. The obtained data can be sent through the wireless transmitter module, and be received by the wireless receiver module, and ultimately be processed by computer to get the motion parameters of the discus. Dynamic information was Real-time accessed. Computer can be used to process the data and storage useful information. The system can also be used for measurements separately, and simultaneous measurements with other instruments. Sports researchers can make use of this instrument and such measurements. They can explore a new theory and discover new laws of the discus throwing by collected data.The hardware circuit system of digital discus studied by this paper had been validated after the actual throwing experiment. The collected data of3D acceleration and3D angular velocity were relatively accurate, real-time wireless transmission, the device is stable. Wireless transmission of data through wireless RF module overcomes the limitations of traditional wired transmission equipment. The system provides an effective means for remote access to data.
