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。

云计算失宠伦敦奥运会 Cloud computing disfavor London Olympic Games

　　奥运期间，伦敦互联网基础设施的网络流量将达到一个惊人数字。为了确保2012年伦敦奥运会的顺利进行，负责运营IT基础设施的公司更注重所采用技术的可靠性，而不是尖端性。这也就意味着云计算等热门技术在伦敦奥运会上没有施展空间，无法成为IT基础设施核心的一部分。

During the Olympic Games，London Internet infrastructure network traffic will reach an astonishing number。In order to ensure that the 2012 Olympic Games in London smoothly，Responsible for the operation of the IT infrastructure company pay more attention to the reliability of the technology，Not sophisticated sex。This also means that cloud computing hot technology such as in London games have not performed space，Can't become a core part of IT infrastructure。

　　法国源讯公司是负责运营伦敦奥运会技术基础设施的IT服务提供商的领导者，其首席集成官米歇尔-海朗在接受采访时表示：“我们采用了一些虚拟化技术，但不会采用云技术。我们始终将目光聚焦已得到验证的成熟技术。”

The French company is responsible for the operation of the source-London Olympic Games technology infrastructure IT service provider leader，Its chief integrated officer michelle-the sea lang said in an interview：“We adopted some virtualization technology，But not in cloud technology。We always focused attention on the established mature technology。”

　　海朗指出：“2009年进行分析时，我们就不准备采用云技术。它虽然是一项非常有趣的技术，但将其用于奥运会对我们来说还早了些。”

The sea lang points out that：“In 2009 when analysis，We will not prepared to adopt cloud technology。Although it is a very interesting technology，But on the Olympic Games for us was early enough。”

　　最近，负责奥运会IT系统的团队完成了第一次技术装备彩排，官员们为演练设计了一系列可能发生的事故并对演练过程进行监督，考验技术负责团队的应变能力。他们设计的事故包括拔掉设备的插头或者有人请病假，这些都是有可能在奥运会举行期间发生的事故。

recent，Responsible for the Olympic Games IT system team finished first technical equipment the rehearsal，Officials for drill design a series of possible accident and the practice process of supervision，Responsible for the test technology team capability。Design of their accidents including pulled out the plug of the equipment or someone please sick leave，These are possible in the Olympic Games accident。
