近(jin)日，隨著重慶地鐵(tie)五號(hao)線一期信號(hao)系統互(hu)(hu)聯互(hu)(hu)通(tong)交(jiao)叉測試的成功(gong)，裝備中國(guo)通(tong)號(hao)完全自主CBTC信號(hao)系統的重慶軌道交(jiao)通(tong)5號(hao)線率先具備互(hu)(hu)聯互(hu)(hu)通(tong)條(tiao)(tiao)件，標志著由(you)中國(guo)通(tong)號(hao)打(da)造的全球(qiu)首條(tiao)(tiao)互(hu)(hu)聯互(hu)(hu)通(tong)地鐵(tie)即將孕育而(er)生。

長期以來(lai)，由于(yu)不(bu)同地(di)(di)鐵(tie)線路車載信(xin)號設備與地(di)(di)面(mian)信(xin)號設備間(jian)(jian)無法“交(jiao)流”，導致列車跨線運(yun)行一直是(shi)一項世界(jie)性難題，國(guo)(guo)外曾努力(li)嘗(chang)試但始(shi)終(zhong)沒有實現不(bu)同廠家間(jian)(jian)的地(di)(di)鐵(tie)信(xin)號系(xi)統互(hu)通(tong)(tong)。在我國(guo)(guo)，隨著(zhu)以中(zhong)國(guo)(guo)通(tong)(tong)號CBTC信(xin)號系(xi)統為代(dai)表的自(zi)主知識產權信(xin)號系(xi)統的成熟應用(yong)，我國(guo)(guo)已編(bian)制(zhi)出了適(shi)應中(zhong)國(guo)(guo)國(guo)(guo)情的互(hu)聯(lian)互(hu)通(tong)(tong)技術標(biao)準，真正意義上建立了不(bu)同廠家之(zhi)間(jian)(jian)、車載信(xin)號系(xi)統與地(di)(di)面(mian)信(xin)號系(xi)統之(zhi)間(jian)(jian)，互(hu)相(xiang)兼容、互(hu)相(xiang)“交(jiao)流”的基礎，一舉解決了這個世界(jie)性難題。地(di)(di)鐵(tie)互(hu)聯(lian)互(hu)通(tong)(tong)后，可(ke)以滿足乘(cheng)客一站式(shi)“直達”的需求，減少客流換乘(cheng)壓(ya)力(li)，降低(di)地(di)(di)鐵(tie)建成本資，大幅(fu)度提(ti)高車輛利用(yong)率和運(yun)營效(xiao)率。

重慶5號(hao)線(xian)(xian)裝備的FZL300型CBTC互(hu)(hu)聯(lian)(lian)互(hu)(hu)通信號(hao)系統(tong)是(shi)中(zhong)國通號(hao)自主研發，為城市軌(gui)(gui)道(dao)交通“互(hu)(hu)聯(lian)(lian)互(hu)(hu)通”量(liang)身定制的基于無(wu)線(xian)(xian)通信的移動閉塞系統(tong)，可(ke)實(shi)現(xian)列(lie)車(che)最小90秒(miao)追蹤間(jian)隔。在原有(you)CBTC列(lie)車(che)控制系統(tong)的基礎上(shang)，該系統(tong)可(ke)實(shi)現(xian)列(lie)車(che)不降速降級跨線(xian)(xian)運(yun)(yun)營至其(qi)(qi)它(ta)線(xian)(xian)路，并支(zhi)持其(qi)(qi)它(ta)線(xian)(xian)路車(che)輛(liang)進入本線(xian)(xian)運(yun)(yun)行，滿足城市軌(gui)(gui)道(dao)交通未來聯(lian)(lian)通聯(lian)(lian)運(yun)(yun)需求，對節約(yue)旅客出行時間(jian)、提高城市軌(gui)(gui)道(dao)交通運(yun)(yun)營效率具有(you)重要意義。

重慶地(di)鐵5號(hao)線(xian)（一(yi)期）工(gong)程(cheng)(cheng)北(bei)起園博中(zhong)(zhong)(zhong)心(xin)站(zhan)南至(zhi)跳蹬站(zhan)，線(xian)路長(chang)39.75km，設車站(zhan)25座(zuo)，最高運(yun)行(xing)時速(su)可達100公(gong)里。工(gong)程(cheng)(cheng)分段建設開通，其中(zhong)(zhong)(zhong)首(shou)(shou)通段擬于2017年底開通運(yun)營，成為全球首(shou)(shou)條(tiao)實現(xian)城市軌道交通互聯互通的(de)地(di)鐵線(xian)路。中(zhong)(zhong)(zhong)國(guo)通號(hao)旗下城軌公(gong)司(si)負責(ze)整(zheng)體(ti)工(gong)程(cheng)(cheng)組(zu)織實施及信(xin)號(hao)系統集成；研究設計院集團(tuan)負責(ze)核心(xin)系統的(de)設計、研發；上海工(gong)程(cheng)(cheng)局負責(ze)施工(gong)安裝工(gong)作，其核心(xin)產(chan)品均由中(zhong)(zhong)(zhong)國(guo)通號(hao)各工(gong)業(ye)企業(ye)自主生產(chan)，充分凸(tu)顯了中(zhong)(zhong)(zhong)國(guo)通號(hao)設計研發、裝備制造、工(gong)程(cheng)(cheng)服務“三位一(yi)體(ti)”的(de)完整(zheng)產(chan)業(ye)鏈優勢，是中(zhong)(zhong)(zhong)國(guo)通號(hao)整(zheng)體(ti)品牌優勢的(de)又一(yi)次集中(zhong)(zhong)(zhong)體(ti)現(xian)。

信(xin)號(hao)系(xi)統(tong)是(shi)(shi)軌道(dao)(dao)交通的“大腦”，是(shi)(shi)控制(zhi)車輛安(an)全(quan)(quan)、高效運(yun)(yun)行的神(shen)經(jing)中樞，指揮全(quan)(quan)線列車以高密度(du)、高速度(du)、舒適運(yun)(yun)行。FZL300型互(hu)聯互(hu)通移動(dong)閉塞系(xi)統(tong)是(shi)(shi)中國通號(hao)在成(cheng)熟(shu)的高鐵列控技術標(biao)準(zhun)基(ji)礎上，依據國內(nei)城市軌道(dao)(dao)交通信(xin)號(hao)系(xi)統(tong)“互(hu)聯互(hu)通”標(biao)準(zhun)，對(dui)原有CBTC系(xi)統(tong)進行升級而形成(cheng)的列車運(yun)(yun)行控制(zhi)系(xi)統(tong)。系(xi)統(tong)采用了全(quan)(quan)新的LTE車地通信(xin)技術，替(ti)代了原有WLAN技術，支持更高的移動(dong)接入(ru)速度(du)，安(an)全(quan)(quan)性和抗干擾能力更強，并(bing)且預留了多(duo)專業綜合承載條件。

建設(she)(she)期間(jian)，中國(guo)通(tong)(tong)(tong)(tong)號會同(tong)國(guo)內信號廠(chang)商，在中國(guo)城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)(tong)協會技術(shu)裝(zhuang)備委員會牽頭下共同(tong)編制了CBTC互(hu)聯(lian)互(hu)通(tong)(tong)(tong)(tong)技術(shu)標準(zhun)(zhun)，旨在促進中國(guo)城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)(tong)建設(she)(she)，實現并滿足城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)(tong)互(hu)聯(lian)互(hu)通(tong)(tong)(tong)(tong)的(de)需求，達到經濟適用、資源共享、技術(shu)先進及可持續發展(zhan)的(de)目的(de)。這也(ye)是城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)(tong)在世(shi)界范圍內一(yi)次(ci)創(chuang)新的(de)革(ge)命與探索，為城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)(tong)的(de)產品通(tong)(tong)(tong)(tong)用化(hua)、技術(shu)標準(zhun)(zhun)化(hua)、網絡化(hua)運(yun)營邁出了重要的(de)一(yi)步。目前，長沙地(di)鐵也(ye)確定使用CBTC互(hu)聯(lian)互(hu)通(tong)(tong)(tong)(tong)技術(shu)標準(zhun)(zhun)，互(hu)聯(lian)互(hu)通(tong)(tong)(tong)(tong)技術(shu)得(de)以進一(yi)步應用。
