近(jin)日，隨著重慶(qing)地(di)(di)鐵五號(hao)(hao)線一(yi)期信號(hao)(hao)系(xi)統互(hu)聯互(hu)通(tong)(tong)交(jiao)叉測(ce)試的(de)(de)成功(gong)，裝備中(zhong)國通(tong)(tong)號(hao)(hao)完全自主CBTC信號(hao)(hao)系(xi)統的(de)(de)重慶(qing)軌(gui)道交(jiao)通(tong)(tong)5號(hao)(hao)線率先具備互(hu)聯互(hu)通(tong)(tong)條件，標志(zhi)著由中(zhong)國通(tong)(tong)號(hao)(hao)打造(zao)的(de)(de)全球首條互(hu)聯互(hu)通(tong)(tong)地(di)(di)鐵即(ji)將孕育而生(sheng)。

長(chang)期以來(lai)，由于不(bu)同(tong)地(di)鐵(tie)(tie)線路車(che)(che)載(zai)信(xin)(xin)號(hao)設(she)備與地(di)面(mian)信(xin)(xin)號(hao)設(she)備間無法“交流”，導致(zhi)列車(che)(che)跨線運行(xing)一(yi)直是一(yi)項世界性難題(ti)，國(guo)(guo)(guo)外曾努力嘗(chang)試但始(shi)終(zhong)沒有(you)實現(xian)不(bu)同(tong)廠(chang)家間的(de)地(di)鐵(tie)(tie)信(xin)(xin)號(hao)系(xi)統(tong)互(hu)通(tong)(tong)。在我(wo)國(guo)(guo)(guo)，隨著以中(zhong)(zhong)國(guo)(guo)(guo)通(tong)(tong)號(hao)CBTC信(xin)(xin)號(hao)系(xi)統(tong)為代表的(de)自(zi)主知識產權信(xin)(xin)號(hao)系(xi)統(tong)的(de)成熟應用，我(wo)國(guo)(guo)(guo)已(yi)編(bian)制出了適應中(zhong)(zhong)國(guo)(guo)(guo)國(guo)(guo)(guo)情(qing)的(de)互(hu)聯互(hu)通(tong)(tong)技(ji)術標準，真(zhen)正意義上建(jian)立了不(bu)同(tong)廠(chang)家之間、車(che)(che)載(zai)信(xin)(xin)號(hao)系(xi)統(tong)與地(di)面(mian)信(xin)(xin)號(hao)系(xi)統(tong)之間，互(hu)相兼容、互(hu)相“交流”的(de)基(ji)礎，一(yi)舉解(jie)決了這(zhe)個世界性難題(ti)。地(di)鐵(tie)(tie)互(hu)聯互(hu)通(tong)(tong)后，可以滿足乘客一(yi)站(zhan)式“直達(da)”的(de)需求(qiu)，減少(shao)客流換乘壓力，降低地(di)鐵(tie)(tie)建(jian)成本資，大(da)幅度提高(gao)車(che)(che)輛利用率(lv)和運營效率(lv)。

上圖為(wei)建設中的重慶地鐵5號線(xian)

重(zhong)慶(qing)5號線(xian)(xian)裝備的(de)FZL300型CBTC互(hu)聯(lian)互(hu)通(tong)(tong)信(xin)號系(xi)統(tong)是中國通(tong)(tong)號自主研發(fa)，為城(cheng)(cheng)市軌(gui)道交通(tong)(tong)“互(hu)聯(lian)互(hu)通(tong)(tong)”量(liang)身定制的(de)基于(yu)無線(xian)(xian)通(tong)(tong)信(xin)的(de)移動閉塞系(xi)統(tong)，可實現列車(che)最小(xiao)90秒(miao)追蹤間隔(ge)。在原有CBTC列車(che)控制系(xi)統(tong)的(de)基礎上，該系(xi)統(tong)可實現列車(che)不降速降級跨線(xian)(xian)運(yun)(yun)營(ying)至(zhi)其(qi)它線(xian)(xian)路(lu)，并支持其(qi)它線(xian)(xian)路(lu)車(che)輛(liang)進入本線(xian)(xian)運(yun)(yun)行(xing)，滿足城(cheng)(cheng)市軌(gui)道交通(tong)(tong)未來聯(lian)通(tong)(tong)聯(lian)運(yun)(yun)需求，對節(jie)約旅客出行(xing)時間、提高(gao)城(cheng)(cheng)市軌(gui)道交通(tong)(tong)運(yun)(yun)營(ying)效率(lv)具有重(zhong)要(yao)意義(yi)。

重慶地鐵5號(hao)(hao)(hao)(hao)線（一期）工(gong)程北起園博中(zhong)心站南至跳(tiao)蹬站，線路(lu)長39.75km，設車(che)站25座，最高運行時速可達100公里(li)。工(gong)程分段建設開通(tong)(tong)(tong)(tong)，其中(zhong)首通(tong)(tong)(tong)(tong)段擬于2017年(nian)底開通(tong)(tong)(tong)(tong)運營，成為(wei)全球首條實現城市軌道交通(tong)(tong)(tong)(tong)互聯互通(tong)(tong)(tong)(tong)的(de)地鐵線路(lu)。中(zhong)國(guo)(guo)通(tong)(tong)(tong)(tong)號(hao)(hao)(hao)(hao)旗(qi)下城軌公司負責整體工(gong)程組織(zhi)實施及(ji)信(xin)號(hao)(hao)(hao)(hao)系(xi)統集成；研究設計(ji)(ji)院集團(tuan)負責核心系(xi)統的(de)設計(ji)(ji)、研發(fa)；上海工(gong)程局負責施工(gong)安裝工(gong)作，其核心產(chan)品(pin)均(jun)由中(zhong)國(guo)(guo)通(tong)(tong)(tong)(tong)號(hao)(hao)(hao)(hao)各(ge)工(gong)業企業自主生產(chan)，充分凸顯了中(zhong)國(guo)(guo)通(tong)(tong)(tong)(tong)號(hao)(hao)(hao)(hao)設計(ji)(ji)研發(fa)、裝備制造、工(gong)程服務(wu)“三位一體”的(de)完(wan)整產(chan)業鏈優勢，是中(zhong)國(guo)(guo)通(tong)(tong)(tong)(tong)號(hao)(hao)(hao)(hao)整體品(pin)牌(pai)優勢的(de)又一次集中(zhong)體現。

信(xin)號(hao)(hao)系統(tong)是軌道交通(tong)(tong)的(de)(de)“大(da)腦”，是控制(zhi)車(che)輛安全、高效運行(xing)(xing)的(de)(de)神經中樞，指揮全線列車(che)以(yi)高密度(du)、高速度(du)、舒(shu)適運行(xing)(xing)。FZL300型互(hu)聯(lian)互(hu)通(tong)(tong)移動閉塞系統(tong)是中國通(tong)(tong)號(hao)(hao)在成熟的(de)(de)高鐵列控技術標準(zhun)基礎上，依據國內城市軌道交通(tong)(tong)信(xin)號(hao)(hao)系統(tong)“互(hu)聯(lian)互(hu)通(tong)(tong)”標準(zhun)，對原有CBTC系統(tong)進行(xing)(xing)升(sheng)級而形成的(de)(de)列車(che)運行(xing)(xing)控制(zhi)系統(tong)。系統(tong)采用了全新(xin)的(de)(de)LTE車(che)地通(tong)(tong)信(xin)技術，替(ti)代了原有WLAN技術，支持更高的(de)(de)移動接(jie)入(ru)速度(du)，安全性和抗干(gan)擾能力(li)更強，并(bing)且預留(liu)了多專業綜(zong)合(he)承載條件。

建設期間，中(zhong)國(guo)通號(hao)會(hui)同國(guo)內信號(hao)廠商，在(zai)中(zhong)國(guo)城(cheng)(cheng)市(shi)軌道(dao)交通協會(hui)技(ji)(ji)術(shu)裝(zhuang)備委員會(hui)牽頭下共同編制了CBTC互(hu)聯(lian)互(hu)通技(ji)(ji)術(shu)標準，旨在(zai)促進(jin)中(zhong)國(guo)城(cheng)(cheng)市(shi)軌道(dao)交通建設，實現并滿(man)足城(cheng)(cheng)市(shi)軌道(dao)交通互(hu)聯(lian)互(hu)通的(de)(de)需求(qiu)，達(da)到經(jing)濟適用、資(zi)源(yuan)共享、技(ji)(ji)術(shu)先(xian)進(jin)及(ji)可持續發展的(de)(de)目(mu)的(de)(de)。這也是城(cheng)(cheng)市(shi)軌道(dao)交通在(zai)世界范圍內一次(ci)創(chuang)新(xin)的(de)(de)革命與探索，為城(cheng)(cheng)市(shi)軌道(dao)交通的(de)(de)產品通用化(hua)、技(ji)(ji)術(shu)標準化(hua)、網(wang)絡化(hua)運營邁出了重要的(de)(de)一步。目(mu)前，長沙(sha)地鐵也確定使用CBTC互(hu)聯(lian)互(hu)通技(ji)(ji)術(shu)標準，互(hu)聯(lian)互(hu)通技(ji)(ji)術(shu)得以(yi)進(jin)一步應用。
