       一場(chang)馬拉(la)松賽事少則千八百人(ren)(ren)，多則幾萬人(ren)(ren)。選手快速(su)同時(shi)通過(guo)計(ji)時(shi)點，如(ru)何記錄每個人(ren)(ren)的(de)(de)時(shi)間？到終點時(shi)，成(cheng)績如(ru)何記錄統計(ji)？如(ru)何保證選手通過(guo)時(shi)不被漏記？如(ru)何防作(zuo)弊？為(wei)什么有的(de)(de)比賽結束幾天還沒出來官方成(cheng)績？

 引(yin)入艾德(de)沃克RFID計(ji)(ji)時(shi)(shi)(shi)芯(xin)片(pian)(pian)可以有效解決上述問題(ti)。現在普遍的計(ji)(ji)時(shi)(shi)(shi)芯(xin)片(pian)(pian)存在方式(shi)(shi)有：1、號(hao)碼布(bu)芯(xin)片(pian)(pian)，即(ji)號(hao)碼布(bu)背面粘貼計(ji)(ji)時(shi)(shi)(shi)芯(xin)片(pian)(pian)；2、手腕帶計(ji)(ji)時(shi)(shi)(shi)芯(xin)片(pian)(pian)；3、卡片(pian)(pian)式(shi)(shi)計(ji)(ji)時(shi)(shi)(shi)芯(xin)片(pian)(pian)，多(duo)數(shu)用(yong)于綁在鞋帶上；4、綁帶式(shi)(shi)，多(duo)數(shu)用(yong)于鐵(tie)三(san)等(deng)需要(yao)下水的項目，芯(xin)片(pian)(pian)需要(yao)做防水、抗金屬(shu)處理(li)。

      RFID芯(xin)片計(ji)時(shi)(shi)的(de)(de)(de)好處(chu)是：1、通(tong)(tong)過(guo)(guo)被動感應芯(xin)片，選(xuan)手(shou)(shou)經過(guo)(guo)時(shi)(shi)通(tong)(tong)過(guo)(guo)預設的(de)(de)(de)計(ji)時(shi)(shi)模塊感應并記(ji)錄選(xuan)手(shou)(shou)通(tong)(tong)過(guo)(guo)的(de)(de)(de)時(shi)(shi)間(jian)(jian)(jian)，以(yi)達到(dao)計(ji)時(shi)(shi)效果；2、良好的(de)(de)(de)群讀能(neng)力以(yi)及感應靈敏度，選(xuan)手(shou)(shou)通(tong)(tong)過(guo)(guo)時(shi)(shi)不(bu)需要減速或(huo)者(zhe)停留(liu)打卡，按正常節奏以(yi)及速率經過(guo)(guo)即可，高靈敏度以(yi)及高頻率的(de)(de)(de)信(xin)號發射(she)間(jian)(jian)(jian)隔最大限度的(de)(de)(de)避免(mian)了選(xuan)手(shou)(shou)通(tong)(tong)過(guo)(guo)漏讀的(de)(de)(de)可能(neng)。由于是被動記(ji)錄，所以(yi)通(tong)(tong)過(guo)(guo)沿途預設的(de)(de)(de)各(ge)個(ge)計(ji)時(shi)(shi)點來確定選(xuan)手(shou)(shou)路線，杜絕選(xuan)手(shou)(shou)抄近路以(yi)及各(ge)種(zhong)人為的(de)(de)(de)作弊。比賽結束時(shi)(shi)，通(tong)(tong)過(guo)(guo)數(shu)據網絡上傳或(huo)者(zhe)數(shu)據導出，在各(ge)個(ge)計(ji)時(shi)(shi)點都有有效成績的(de)(de)(de)情況下，起點時(shi)(shi)間(jian)(jian)(jian)（起跑時(shi)(shi)間(jian)(jian)(jian)）與終(zhong)點的(de)(de)(de)時(shi)(shi)間(jian)(jian)(jian)差既為選(xuan)手(shou)(shou)最終(zhong)成績。
