近日，隨著(zhu)重慶地鐵五(wu)號線一期信號系(xi)統互(hu)聯互(hu)通(tong)交叉(cha)測試的(de)成(cheng)功，裝(zhuang)備(bei)(bei)中國(guo)通(tong)號完全自主CBTC信號系(xi)統的(de)重慶軌道交通(tong)5號線率先具備(bei)(bei)互(hu)聯互(hu)通(tong)條(tiao)件，標(biao)志著(zhu)由中國(guo)通(tong)號打(da)造的(de)全球首條(tiao)互(hu)聯互(hu)通(tong)地鐵即將孕育(yu)而生。

長期以(yi)來(lai)，由于不同(tong)地(di)鐵(tie)(tie)線路車載信(xin)號設(she)備與地(di)面信(xin)號設(she)備間無法(fa)“交流(liu)”，導致列車跨線運行一直(zhi)是(shi)一項世界性(xing)難題，國(guo)外(wai)曾努力(li)嘗試(shi)但(dan)始(shi)終沒有(you)實現不同(tong)廠(chang)家間的(de)地(di)鐵(tie)(tie)信(xin)號系統(tong)(tong)互通(tong)。在我國(guo)，隨著以(yi)中國(guo)通(tong)號CBTC信(xin)號系統(tong)(tong)為代表的(de)自主知識(shi)產權(quan)信(xin)號系統(tong)(tong)的(de)成(cheng)熟應(ying)用(yong)，我國(guo)已編(bian)制(zhi)出了(le)(le)(le)適應(ying)中國(guo)國(guo)情的(de)互聯(lian)互通(tong)技術(shu)標(biao)準，真正意(yi)義上建(jian)(jian)立了(le)(le)(le)不同(tong)廠(chang)家之間、車載信(xin)號系統(tong)(tong)與地(di)面信(xin)號系統(tong)(tong)之間，互相兼容、互相“交流(liu)”的(de)基礎，一舉解決了(le)(le)(le)這個世界性(xing)難題。地(di)鐵(tie)(tie)互聯(lian)互通(tong)后(hou)，可以(yi)滿足(zu)乘客一站式“直(zhi)達”的(de)需求，減少客流(liu)換乘壓力(li)，降低地(di)鐵(tie)(tie)建(jian)(jian)成(cheng)本資(zi)，大(da)幅(fu)度提(ti)高車輛利用(yong)率和運營效率。

上圖為(wei)建設(she)中(zhong)的重慶地鐵5號線

重慶5號線(xian)(xian)裝備(bei)的FZL300型CBTC互(hu)聯互(hu)通(tong)(tong)(tong)信(xin)號系(xi)統是中(zhong)國通(tong)(tong)(tong)號自主研發，為城市(shi)軌道交通(tong)(tong)(tong)“互(hu)聯互(hu)通(tong)(tong)(tong)”量身定制(zhi)的基于無線(xian)(xian)通(tong)(tong)(tong)信(xin)的移動閉塞(sai)系(xi)統，可(ke)實現列(lie)車(che)(che)最小90秒(miao)追蹤(zong)間(jian)隔。在(zai)原有(you)CBTC列(lie)車(che)(che)控制(zhi)系(xi)統的基礎上，該(gai)系(xi)統可(ke)實現列(lie)車(che)(che)不降速降級跨(kua)線(xian)(xian)運(yun)營至其(qi)它線(xian)(xian)路，并支持其(qi)它線(xian)(xian)路車(che)(che)輛進(jin)入本線(xian)(xian)運(yun)行(xing)(xing)，滿(man)足(zu)城市(shi)軌道交通(tong)(tong)(tong)未(wei)來聯通(tong)(tong)(tong)聯運(yun)需求，對節約旅客出行(xing)(xing)時(shi)間(jian)、提高城市(shi)軌道交通(tong)(tong)(tong)運(yun)營效率具有(you)重要(yao)意義。

重慶(qing)地鐵5號(hao)線（一期）工(gong)程(cheng)(cheng)(cheng)北起園博中心站南(nan)至跳蹬站，線路(lu)長39.75km，設(she)(she)車(che)站25座，最高(gao)運行(xing)時速可達100公里。工(gong)程(cheng)(cheng)(cheng)分段建設(she)(she)開通(tong)(tong)，其中首通(tong)(tong)段擬于2017年(nian)底開通(tong)(tong)運營，成為全球首條(tiao)實現城市軌道交通(tong)(tong)互聯互通(tong)(tong)的地鐵線路(lu)。中國(guo)通(tong)(tong)號(hao)旗下城軌公司(si)負責整體(ti)(ti)(ti)工(gong)程(cheng)(cheng)(cheng)組(zu)織實施及(ji)信號(hao)系(xi)統(tong)(tong)集(ji)(ji)成；研究設(she)(she)計院集(ji)(ji)團負責核心系(xi)統(tong)(tong)的設(she)(she)計、研發；上海工(gong)程(cheng)(cheng)(cheng)局負責施工(gong)安(an)裝工(gong)作，其核心產品均由中國(guo)通(tong)(tong)號(hao)各工(gong)業(ye)企業(ye)自主生(sheng)產，充分凸顯了中國(guo)通(tong)(tong)號(hao)設(she)(she)計研發、裝備(bei)制造、工(gong)程(cheng)(cheng)(cheng)服務(wu)“三(san)位一體(ti)(ti)(ti)”的完整產業(ye)鏈優勢，是中國(guo)通(tong)(tong)號(hao)整體(ti)(ti)(ti)品牌優勢的又一次集(ji)(ji)中體(ti)(ti)(ti)現。

信號(hao)系(xi)統(tong)(tong)是軌道(dao)交通(tong)的(de)“大腦(nao)”，是控制車輛安全(quan)(quan)、高(gao)(gao)效運(yun)行(xing)的(de)神經中(zhong)樞，指揮(hui)全(quan)(quan)線列(lie)(lie)車以高(gao)(gao)密度、高(gao)(gao)速度、舒(shu)適運(yun)行(xing)。FZL300型(xing)互(hu)聯(lian)互(hu)通(tong)移(yi)動閉塞(sai)系(xi)統(tong)(tong)是中(zhong)國通(tong)號(hao)在成(cheng)熟的(de)高(gao)(gao)鐵列(lie)(lie)控技術標準(zhun)基礎上，依據(ju)國內城市軌道(dao)交通(tong)信號(hao)系(xi)統(tong)(tong)“互(hu)聯(lian)互(hu)通(tong)”標準(zhun)，對原有CBTC系(xi)統(tong)(tong)進行(xing)升級而形成(cheng)的(de)列(lie)(lie)車運(yun)行(xing)控制系(xi)統(tong)(tong)。系(xi)統(tong)(tong)采用了(le)(le)全(quan)(quan)新的(de)LTE車地通(tong)信技術，替代(dai)了(le)(le)原有WLAN技術，支(zhi)持更高(gao)(gao)的(de)移(yi)動接入(ru)速度，安全(quan)(quan)性和(he)抗干擾能力更強，并且(qie)預留了(le)(le)多專業綜(zong)合承載條件。

建設期間，中國(guo)通(tong)(tong)(tong)號會(hui)同國(guo)內信號廠商(shang)，在(zai)中國(guo)城(cheng)市(shi)(shi)(shi)軌(gui)(gui)道(dao)交(jiao)(jiao)通(tong)(tong)(tong)協會(hui)技(ji)(ji)(ji)術(shu)(shu)裝備委員會(hui)牽頭(tou)下(xia)共同編(bian)制(zhi)了(le)CBTC互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)(tong)(tong)技(ji)(ji)(ji)術(shu)(shu)標準，旨(zhi)在(zai)促(cu)進(jin)中國(guo)城(cheng)市(shi)(shi)(shi)軌(gui)(gui)道(dao)交(jiao)(jiao)通(tong)(tong)(tong)建設，實現并滿足(zu)城(cheng)市(shi)(shi)(shi)軌(gui)(gui)道(dao)交(jiao)(jiao)通(tong)(tong)(tong)互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)(tong)(tong)的需(xu)求(qiu)，達到(dao)經濟適用(yong)、資源(yuan)共享(xiang)、技(ji)(ji)(ji)術(shu)(shu)先進(jin)及可持續發展(zhan)的目(mu)的。這也是城(cheng)市(shi)(shi)(shi)軌(gui)(gui)道(dao)交(jiao)(jiao)通(tong)(tong)(tong)在(zai)世界范圍(wei)內一(yi)次創新的革命(ming)與(yu)探索，為城(cheng)市(shi)(shi)(shi)軌(gui)(gui)道(dao)交(jiao)(jiao)通(tong)(tong)(tong)的產(chan)品(pin)通(tong)(tong)(tong)用(yong)化、技(ji)(ji)(ji)術(shu)(shu)標準化、網(wang)絡(luo)化運營(ying)邁出了(le)重要的一(yi)步。目(mu)前，長沙地(di)鐵也確(que)定使用(yong)CBTC互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)(tong)(tong)技(ji)(ji)(ji)術(shu)(shu)標準，互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)(tong)(tong)技(ji)(ji)(ji)術(shu)(shu)得以進(jin)一(yi)步應用(yong)。
