12月28日10點，由中國通(tong)號提供完全自主(zhu)知識產權CBTC信號系統的重慶地鐵5號線正(zheng)式(shi)開通(tong)試運營(ying)。重慶地鐵5號線由此成為全球首條實現(xian)城(cheng)市(shi)(shi)軌(gui)道交通(tong)互(hu)(hu)聯互(hu)(hu)通(tong)的地鐵線路，引領城(cheng)市(shi)(shi)軌(gui)道交通(tong)互(hu)(hu)聯互(hu)(hu)通(tong)時代正(zheng)式(shi)到(dao)來，標志(zhi)著我國城(cheng)市(shi)(shi)軌(gui)道交通(tong)互(hu)(hu)聯互(hu)(hu)通(tong)技術走在世界前列。
重慶5號(hao)(hao)線(xian)裝備的(de)FZL300型(xing)CBTC互聯(lian)(lian)互通(tong)(tong)(tong)信(xin)號(hao)(hao)系統是中國(guo)通(tong)(tong)(tong)號(hao)(hao)在成熟的(de)高鐵列(lie)控技術標準基礎上，自主研發的(de)基于(yu)無線(xian)通(tong)(tong)(tong)信(xin)的(de)移動(dong)閉(bi)塞系統。該(gai)系統依據國(guo)內城(cheng)市(shi)軌(gui)道(dao)交通(tong)(tong)(tong)信(xin)號(hao)(hao)系統“互聯(lian)(lian)互通(tong)(tong)(tong)”標準研發，為城(cheng)市(shi)軌(gui)道(dao)交通(tong)(tong)(tong)“互聯(lian)(lian)互通(tong)(tong)(tong)”量身定制，可實(shi)現列(lie)車(che)最小90秒追蹤間隔(ge)。在原有(you)CBTC列(lie)車(che)控制系統的(de)基礎上，該(gai)系統可實(shi)現列(lie)車(che)不(bu)降(jiang)速降(jiang)級跨線(xian)運營(ying)至(zhi)其(qi)它線(xian)路，并(bing)支持(chi)其(qi)它線(xian)路車(che)輛進入(ru)本線(xian)運行，滿足城(cheng)市(shi)軌(gui)道(dao)交通(tong)(tong)(tong)聯(lian)(lian)通(tong)(tong)(tong)聯(lian)(lian)運需求，對節約(yue)旅客出(chu)行時間、提高城(cheng)市(shi)軌(gui)道(dao)交通(tong)(tong)(tong)運營(ying)效率具有(you)重要(yao)意義。
信(xin)(xin)號(hao)系統是軌道交(jiao)(jiao)通(tong)(tong)的“大腦(nao)”，是控制車輛安全、高(gao)效運(yun)行的神經中(zhong)樞。重慶地鐵5號(hao)線的順利開通(tong)(tong)，真正解決(jue)了(le)不同信(xin)(xin)號(hao)廠家車地設備之間彼(bi)此“交(jiao)(jiao)流”的世界(jie)性(xing)技(ji)術難題，建(jian)立統一的信(xin)(xin)號(hao)系統互聯互通(tong)(tong)技(ji)術標(biao)準，為中(zhong)國(guo)乃(nai)至(zhi)世界(jie)城市軌道交(jiao)(jiao)通(tong)(tong)的建(jian)設、運(yun)營、維護帶來一次歷史性(xing)變革。
據悉，中國通(tong)(tong)號已中標的長(chang)沙地鐵5號線也將繼續沿用CBTC互聯互通(tong)(tong)技術(shu)標準，我國城市(shi)軌道交通(tong)(tong)互聯互通(tong)(tong)技術(shu)將得到(dao)進一步推(tui)廣(guang)應用。
