运动员动态信息捕捉系统研究与设计

Research and Design of Athletes' Dynamic Data Capture System

为节省体能训练与测试的人力投入并提高项目公平可靠性,以射频识别为核心,设计了一套适合于运动场中长距离比赛的运动员动态信息自动捕捉系统。系统采用具有片上系统技术的2.4 GHz射频芯片为核心部件,设计了阅读器和电子标签的软硬件,分析了系统天线有效覆盖半径,引入了RFID防冲突策略,并设计了PC终端信息管理软件。通过实验证明,该系统具有携带方便,响应速度快,成本低廉的特点,可以应用于体能训练和比赛中。

In order to save manpower for physical training and testing and improve the fairness and reliability of the project,this paper designed an automatic capture system of athletes’ dynamic data,which is suitable for long-distance race in stadium by taking radio frequency identification as a core. Based on the2. 4 GHz radio chip with system-on-chip technology,the hardware and software of readers and electronic tags are designed. The effective covering radius of the system antenna was analyzed and RFID anti-collision strategy was introduced. A management software was also designed on PC terminal. The experiments have proved that the system has the characteristics such as portability,fast response and low cost,which thus can be used in physical training and competition.
