基于RFID和WSN的运动计时系统分析与设计

The Analysis and Design of RFID and WSN Based Sports Timing System

本文论述一种将射频识别技术(RFID)和无线传感器网络技术(WSN)应用于体育比赛长距离运动的运动计时系统。系统通过射频识别对运动员配带的RFID传感器标签进行读写,完成对运动员非接触式自动识别,既可以获取运动员的标识信息,也可以获取运动员的身体状态信息如体温、心跳等,还可以获取比赛环境的温度、湿度、风力等信息,再经过无线传感器网络的组织将采集到的数据进行处理,一是实现运动员成绩的准确计时,二是可以通过多方面信息分析该运动员的比赛情况。该系统解决了在长距离运动中计时需要耗费大量人力财力的问题,同时可以对比赛数据进行详细的分析。经过试验表明,系统实现简单,控制方便,效果良好。

This Paper discusses the sports timing system of the long-distance race which applies the RFID technology and WSN. The system reads and writes the information in the RFID sensor tag upon the person through the RFID reader. The information includes the identification of the person, the status of the person, such as temperature and heartbeat, and the status of the surroundings such as temperature humidity and wind power. Through the wireless sensor net, the information can be dealt with to correctly calculate the score of the person and to analyze the state of the person according to the complex data. This system can resolve the resource problem of the long-distance race and can improve the usage of the information to analyze the state. The system is simple, well controlled and effective.
