RFID标签在运动界的出路 擦出不一样的火花

2014年08月25日

      近日美国国家橄榄球联盟(NFL)在橄榄球运动员的垫肩里加装了射频识别技术(RFID)标签。通过标签,观众和裁判都可以了解运动员的运动轨迹和运动状态。事实上,RFID标签已经运用在多项运动当中。

  橄榄球

  NFL为运动员加装的标签里包含了运动传感器,观众可以直观地了解到运动员的速度和加速度,从而了解到冲撞时的撞击力:这些数据会让比赛更加刺激。

  运动轨迹可以让裁判更好地判断运动员是否犯规。橄榄球运动对于球员位置有严格的规则,并且也有越位的规定。以往的判断方法是通过摄像机和人眼判断,但现在能够直接从电脑上看到运动员的位置。通过软件,电脑甚至可以直接提示裁判运动员是否犯规。

  NFL媒体策略副总裁Vishal Shah表示:“Zebra公司的追踪技术能够帮助团队进一步优化培训内容,根据每位球员的能力进而指定更加合理的进攻路线和运输轨迹。而最后为我们的球队、赞助商和球迷之间搭建沟通的桥梁。”

      高尔夫

  位于得克萨斯州的TopGolf高尔夫球场所采用RFID技术,实时显示球员的成绩。该解决方案采用无源EPC Gen 2超高频(UHF)RFID技术测量球移动的距离,同时为每个球员记录得分。标签对200,000个高尔夫球进行追踪,此过程包括548个落球点。

  由于高尔夫球运动占地很广,运动员的球落地后很难马上知道位置,更不用说让观众看到运动轨迹了。但在高尔夫球内加装RFID标签后,观众和运动员能够实时看到球的运动轨迹,并能够马上找到落地点。通过运动传感器,人们也能够了解到运动员击球的力道。

      田径比赛

  1994年柏林的马拉松比赛由Champion Chip开了RIFD的先河,参赛运动员身上带有个人信息的电子标签,通过设定起点和终点,举办方能够通过数据采集点采集信息。从此以后,各种公路赛、滑雪比赛、十项全能都用了这样的技术,计时效率能够大幅提高。

  目前高水品的田径比赛采用激光测距仪来测量距离,但还是要裁判在投掷物落地的那一刹那判断第一落地点,还是会有人为误差。如果在铅球、标枪等物件里植入RFID标签和加速度传感器,那么系统就能够在第一时间里判断落点。

  另外,RFID技术在各类球类比赛里也有很好的应用,但要让这类技术运作需要有很大的投入。就拿高尔夫来说,球场必须安装多个数据采集点。如果 要加装传感器的话,这些运动器材如何充电也是一个问题。很多人将RFID技术做成防丢标签,但不可否认的是,该技术在运动界找到了更好的出路。
