细数伦敦奥运会高科技:游泳用上雷达收发机--亲稳网络舆情监控室
2012-07-26
新闻背景 News background
伦敦奥运会27日即将开幕。奥运会既是选手们较量的战场,更是高科技比赛装置的展示台,也是运动装备比拼的竞技场。与往届一样,伦敦奥运会上也将亮相一系列高科技装置和设备。
London Olympic Games which opens 27,。The Olympic Games is not only the players take on the battlefield,The game is high-tech device for furnishings,Also sports equipment of the competition arena。As scale and,London games also will appear on a series of high-tech device and equipment。
发令枪 gun
计时开始由起跑发令脉冲决定 The clock started by launching the pulse decision
伦敦奥运会将使用新的起跑发令枪。枪响后会同时发生3件事情:选手身后的扩音器播放声音,确保他们同时听到起跑令;发生闪光;向计时装置发送起跑令脉冲。如果在两秒钟内第二次扣动扳机,说明有人抢跑。发令枪的声响可以利用电脑改变和下载。在一些场馆,公共广播系统也会传回起跑令的声音。
London Olympic Games will use the new starting gun。After a shot will occur at the same time three things:Players behind the loudspeakers voice,Ensure that they also start to hear;Happen flash;The timer to send to start pulse。If the second time in two seconds pulled the trigger,That someone jump start。The sound of the gun can use computers to change and download。In some venues,Public radio system would also start back to sound。
起跑器 blocks
通过踏板受力测量起跑反应 Through the pedal force measurement start reaction
在1936年的奥运会上,赛跑选手人手一把铁铲,在起跑线上的煤渣中挖坑以方便起跑时蹬地,“挖坑水平”成为短跑竞赛的一个组成部分。1948年伦敦奥运会的田径比赛第一次使用起跑器,旨在让选手获得平等的起跑条件。
In the 1936 games,Runner with a shovel,At the starting line of cinders to dig in with convenient when starting to push,“Have dug a pit level”Be sprint, a part of the competition。London 1948 Olympic athletics first use of blocks,Aims to make players get equal starting conditions。
2012年伦敦奥运会上,赛跑选手的反应时间将通过测量起跑器后踏板受力的方式得出,而不是通过测量运动。新起跑器能够在不改变设置的情况下测量每一位选手——无论是男选手还是女选手的反应时间。发令枪响后,选手离开起跑器的时间如果少于l/10秒,便被视为抢跑。伦敦奥运会起跑器的中部结构比以往的起跑器细,从80毫米减至50毫米,能够改进选手的起跑姿势,尤其是女选手。此外,踏板的宽度提高,从120毫米提高到160毫米,允许选手采用不同的起跑姿势。
The 2012 London games,The response time of the runners will be measured by the way after blocks pedal force that,Not by measuring the movement。New blocks are not changing Settings measure the every player-whether male or female players the response time of the players。After starting gun,Players leave the blocks if less than time l / 10 seconds,He is considered as the false start。London Olympic Games of the blocks in central structure than the previous blocks is fine,From 80 mm to 50 mm,To improve the players start posture,Especially female athletes。In addition,The width of the pedal improve,From 120 mm to 160 mm improve,Allows players using different starting position。

帮助改进跳远技术 Help to improve the long jump technology
为了帮助奥运选手提高比赛成绩,科学家研究了一系列技术。美国加利福尼亚州的宝马技术办公室推出了速度测量计划,帮助提高美国田径运动员的成绩。宝马的系统利用立体视觉技术和机器视觉算法软件捕捉跳远运动员的运动。
In order to help the Olympic athletes improve match result,Scientists study a series of technology。The California BMW launched velocity measurement technology office plan,Help improve the U.S. track and field athletes grades。BMW's system using stereo vision technology and machine vision algorithm software to capture the long jump of the movement of athletes。
这一系统能够对跳远比赛的3个关键参数进行实时分析,即选手接近起跳板时的速度,垂直起跳速度和起跳角度。宝马用了大约一年时间研发这一系统。他们目前正与美国游泳队合作,对选手的起跳和转身进行运动跟踪分析。
The system of long jump to the game three key parameters for real-time analysis,That is close to the speed of QiTiaoBan players,Vertical take-off speed and takeoff point of view。BMW in about a year time research and development the system。They are working with the U.S. swim team cooperation,Players of the takeoff and turned to track dynamic analysis。
泳池起跳台 Swimming pool QiTiaoTai
踏脚板可自主调整 Pedal adjustment can be independent
伦敦奥运会游泳比赛的一个最明显变化当属新的泳池起跳台。这种起跳台的倾斜式踏脚板可以调整,允许选手以后腿与膝盖呈90度角的蹲伏姿势起跳,让选手获得的起跳力量实现最大化。这种新型起跳台在2009年斯德哥尔摩举行的短池游泳世界杯上首次使用。也就是说,世界顶尖的游泳选手在2012年伦敦奥运会前拥有充足的时间,适应这种起跳台。与赛跑比赛上使用的起跑器一样,游泳比赛的新起跳台也装有一个探测抢跳的系统。同样,游泳比赛也使用声学发令装置,让选手们同时听到起跳令。
London Olympic swimming, one of the most obvious change when the new swimming pool QiTiaoTai。This QiTiaoTai tilting pedal can be adjusted,Allows players leg and knee after with a 90 degree Angle crouching posture of takeoff,Let's get the takeoff of power to achieve maximized。The new QiTiaoTai held in 2009 in Stockholm USES first used swimming World Cup。That is,The world's top swimmer in the 2012 Olympic Games in London has plenty of time before,To adapt to this QiTiaoTai。And the race for use on the same blocks,The swimming new QiTiaoTai also is equipped with a starting before the starting signal detection system。The same,The swimming also use acoustic the device,Let the players also heard that takes off。
