近日(ri)，隨著(zhu)重(zhong)慶(qing)地鐵(tie)五號(hao)(hao)線一(yi)期信號(hao)(hao)系統互(hu)聯(lian)(lian)互(hu)通(tong)交(jiao)叉測試的成功，裝備中(zhong)國通(tong)號(hao)(hao)完全自主CBTC信號(hao)(hao)系統的重(zhong)慶(qing)軌道(dao)交(jiao)通(tong)5號(hao)(hao)線率先具備互(hu)聯(lian)(lian)互(hu)通(tong)條件，標志著(zhu)由中(zhong)國通(tong)號(hao)(hao)打造的全球首條互(hu)聯(lian)(lian)互(hu)通(tong)地鐵(tie)即將孕(yun)育而生。

長期(qi)以來，由于不(bu)同地鐵(tie)(tie)線(xian)路車(che)載信(xin)(xin)號(hao)設備與地面信(xin)(xin)號(hao)設備間(jian)無(wu)法(fa)“交(jiao)流(liu)”，導致(zhi)列車(che)跨線(xian)運行一直(zhi)是一項世(shi)界(jie)性(xing)難題，國(guo)(guo)外曾努力嘗(chang)試但始(shi)終沒有實現不(bu)同廠家間(jian)的(de)(de)地鐵(tie)(tie)信(xin)(xin)號(hao)系(xi)(xi)統(tong)互(hu)(hu)通。在我國(guo)(guo)，隨著以中國(guo)(guo)通號(hao)CBTC信(xin)(xin)號(hao)系(xi)(xi)統(tong)為代(dai)表的(de)(de)自(zi)主知(zhi)識(shi)產權信(xin)(xin)號(hao)系(xi)(xi)統(tong)的(de)(de)成(cheng)熟(shu)應(ying)用(yong)，我國(guo)(guo)已編(bian)制出了(le)適(shi)應(ying)中國(guo)(guo)國(guo)(guo)情的(de)(de)互(hu)(hu)聯互(hu)(hu)通技術標準，真正意義上建(jian)立了(le)不(bu)同廠家之間(jian)、車(che)載信(xin)(xin)號(hao)系(xi)(xi)統(tong)與地面信(xin)(xin)號(hao)系(xi)(xi)統(tong)之間(jian)，互(hu)(hu)相兼容(rong)、互(hu)(hu)相“交(jiao)流(liu)”的(de)(de)基礎，一舉解決了(le)這(zhe)個世(shi)界(jie)性(xing)難題。地鐵(tie)(tie)互(hu)(hu)聯互(hu)(hu)通后(hou)，可以滿足乘客一站式(shi)“直(zhi)達”的(de)(de)需求，減(jian)少客流(liu)換乘壓(ya)力，降低地鐵(tie)(tie)建(jian)成(cheng)本資，大幅度提(ti)高(gao)車(che)輛利用(yong)率和運營效率。

上圖為建設中的重(zhong)慶(qing)地鐵5號(hao)線

重慶5號線裝備的FZL300型CBTC互聯(lian)互通(tong)(tong)(tong)信號系統(tong)是中國(guo)通(tong)(tong)(tong)號自主研發，為城(cheng)市軌(gui)道交(jiao)通(tong)(tong)(tong)“互聯(lian)互通(tong)(tong)(tong)”量身定制的基于無(wu)線通(tong)(tong)(tong)信的移動閉(bi)塞系統(tong)，可實現列(lie)車最小90秒追(zhui)蹤間隔。在(zai)原有CBTC列(lie)車控制系統(tong)的基礎上，該系統(tong)可實現列(lie)車不(bu)降(jiang)(jiang)速降(jiang)(jiang)級跨線運營(ying)至其它線路，并支持(chi)其它線路車輛進入本線運行(xing)，滿足城(cheng)市軌(gui)道交(jiao)通(tong)(tong)(tong)未來聯(lian)通(tong)(tong)(tong)聯(lian)運需求，對節約旅客(ke)出行(xing)時(shi)間、提(ti)高城(cheng)市軌(gui)道交(jiao)通(tong)(tong)(tong)運營(ying)效率具有重要意(yi)義。

重慶地鐵5號(hao)(hao)線(xian)（一(yi)期）工程(cheng)北起(qi)園博中(zhong)心(xin)站(zhan)南至跳蹬站(zhan)，線(xian)路(lu)長39.75km，設車站(zhan)25座，最高運行(xing)時速可達100公(gong)里。工程(cheng)分段(duan)(duan)建(jian)設開通(tong)(tong)，其(qi)中(zhong)首通(tong)(tong)段(duan)(duan)擬于2017年底開通(tong)(tong)運營，成為全球首條(tiao)實(shi)現城市軌(gui)道交通(tong)(tong)互(hu)聯互(hu)通(tong)(tong)的(de)(de)地鐵線(xian)路(lu)。中(zhong)國(guo)(guo)通(tong)(tong)號(hao)(hao)旗下城軌(gui)公(gong)司負責整(zheng)體工程(cheng)組織實(shi)施及信號(hao)(hao)系(xi)統集成；研(yan)究設計(ji)院(yuan)集團負責核(he)心(xin)系(xi)統的(de)(de)設計(ji)、研(yan)發(fa)；上海工程(cheng)局負責施工安(an)裝工作，其(qi)核(he)心(xin)產(chan)品均由中(zhong)國(guo)(guo)通(tong)(tong)號(hao)(hao)各(ge)工業(ye)企業(ye)自(zi)主生產(chan)，充(chong)分凸顯了中(zhong)國(guo)(guo)通(tong)(tong)號(hao)(hao)設計(ji)研(yan)發(fa)、裝備制(zhi)造、工程(cheng)服(fu)務“三位一(yi)體”的(de)(de)完整(zheng)產(chan)業(ye)鏈優(you)勢，是中(zhong)國(guo)(guo)通(tong)(tong)號(hao)(hao)整(zheng)體品牌優(you)勢的(de)(de)又一(yi)次集中(zhong)體現。

信(xin)號系(xi)統(tong)(tong)是(shi)(shi)軌道交通(tong)的(de)(de)“大腦”，是(shi)(shi)控(kong)制(zhi)(zhi)車輛安全(quan)(quan)、高(gao)(gao)效運行的(de)(de)神(shen)經中樞(shu)，指揮全(quan)(quan)線列(lie)車以(yi)高(gao)(gao)密度(du)、高(gao)(gao)速度(du)、舒適運行。FZL300型互(hu)聯互(hu)通(tong)移動(dong)閉塞系(xi)統(tong)(tong)是(shi)(shi)中國通(tong)號在成熟的(de)(de)高(gao)(gao)鐵列(lie)控(kong)技術(shu)(shu)標(biao)準基礎上，依(yi)據國內城(cheng)市軌道交通(tong)信(xin)號系(xi)統(tong)(tong)“互(hu)聯互(hu)通(tong)”標(biao)準，對(dui)原有CBTC系(xi)統(tong)(tong)進行升級而形成的(de)(de)列(lie)車運行控(kong)制(zhi)(zhi)系(xi)統(tong)(tong)。系(xi)統(tong)(tong)采用了全(quan)(quan)新的(de)(de)LTE車地通(tong)信(xin)技術(shu)(shu)，替代了原有WLAN技術(shu)(shu)，支(zhi)持更高(gao)(gao)的(de)(de)移動(dong)接入速度(du)，安全(quan)(quan)性和抗干擾能力更強，并且(qie)預留了多專業綜合承載條(tiao)件。

建(jian)設(she)期間(jian)，中(zhong)(zhong)國(guo)通(tong)號會(hui)同國(guo)內信號廠商，在中(zhong)(zhong)國(guo)城市(shi)軌(gui)(gui)道交(jiao)(jiao)通(tong)協會(hui)技(ji)(ji)術裝備(bei)委員會(hui)牽(qian)頭下共同編(bian)制了CBTC互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)技(ji)(ji)術標(biao)準，旨在促(cu)進中(zhong)(zhong)國(guo)城市(shi)軌(gui)(gui)道交(jiao)(jiao)通(tong)建(jian)設(she)，實現(xian)并滿足城市(shi)軌(gui)(gui)道交(jiao)(jiao)通(tong)互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)的(de)(de)(de)需求(qiu)，達到(dao)經濟適用(yong)(yong)、資源共享、技(ji)(ji)術先(xian)進及可持續發展的(de)(de)(de)目的(de)(de)(de)。這也(ye)是城市(shi)軌(gui)(gui)道交(jiao)(jiao)通(tong)在世界范圍內一(yi)(yi)次(ci)創(chuang)新(xin)的(de)(de)(de)革命與探索，為城市(shi)軌(gui)(gui)道交(jiao)(jiao)通(tong)的(de)(de)(de)產品通(tong)用(yong)(yong)化、技(ji)(ji)術標(biao)準化、網絡(luo)化運營邁出了重要(yao)的(de)(de)(de)一(yi)(yi)步。目前，長沙地鐵也(ye)確定使用(yong)(yong)CBTC互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)技(ji)(ji)術標(biao)準，互(hu)(hu)(hu)聯互(hu)(hu)(hu)通(tong)技(ji)(ji)術得(de)以進一(yi)(yi)步應用(yong)(yong)。
