摘要
研制了一套数字化铁饼三维信息采集系统,该系统包括一个数字化铁饼、USB连线、上位机软件和一台PC计算机,其中,数字化铁饼由上、下壳体、金属圈、电路板、加速度传感器、角速度传感器等组成。该系统能够对运动员完整掷铁饼过程中的用力信号实时采集,进行动力学分析。现场测试表明,数字化铁饼三维信息采集系统动力学数据采集方便可靠,为铁饼项目的技术诊断、科学研究提供了一种崭新的测量方法与手段。
A suit of the three-dimensional information collection system of digital discus has been developed which includes a digital discus, USB connecting line, position machine software and a personal computer. The digital discus is made up of the higher and lower shell, eyelets, circuit boards, accelerometer and angular rate sensor, etc. This system can be used to collect the signals sent out when throwing the discus on the whole process and carry through the dynamics analysis. It indicates on the spot that the dynamics data collection methods are convenient and feasible on using the three-dimensional information collection system of digital discus, which provides a band-new way and instrument for the technical diagnosis and scientific researches of the discus event.
