英国足协正在研究如何将电子技术引入足球比赛。据设想,未来的裁判腰带上插有微型放像机,在遇到判断不准的情况时可重新播放录像;腰带上还插有激光测距器,供在罚任意球等情况下准确测距用;手腕上戴有通信机,可与其他人员通话;手表可以通过无线电与场内的大型电子钟相联,这样观众和运动员、教练员可以准确得知裁判手表上的时间。此外,运动员胸前还佩带电子卡,它发出的无线电波可准确判断运动员的位置,这有利于裁判员、巡边员判断越位。 The British Football Association is studying how to bring electronic technology into football matches. It is envisaged that in the future the referee belt will be inserted with a mini-video player and the video may be replayed in the event of a discrepancy; a laser range finder is inserted into the waistband for accurate ranging in the penalty kick, There is a communication device on the wrist to talk to other people; the watch can be radio-linked to the large electronic clock inside the stadium so viewers, athletes, and coaches can accurately know the time on the referee’s watch. In addition, the athlete’s chest is also wearing an electronic card, which issued a radio wave can accurately determine the position of the athlete, which is conducive to the referee, the lineman to determine the offside.
