12月28日10點，由中國(guo)通(tong)(tong)(tong)號提供完全(quan)自(zi)主知識(shi)產權(quan)CBTC信號系統的重慶地鐵5號線正式開通(tong)(tong)(tong)試運營。重慶地鐵5號線由此成為(wei)全(quan)球首條(tiao)實現城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)互(hu)聯互(hu)通(tong)(tong)(tong)的地鐵線路，引領城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)互(hu)聯互(hu)通(tong)(tong)(tong)時代正式到來，標志著我(wo)國(guo)城(cheng)市(shi)軌道交(jiao)(jiao)通(tong)(tong)(tong)互(hu)聯互(hu)通(tong)(tong)(tong)技術走(zou)在世界前列(lie)。
重慶5號(hao)(hao)線(xian)(xian)裝備的(de)FZL300型CBTC互聯(lian)互通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)號(hao)(hao)系(xi)統是中國通(tong)(tong)(tong)(tong)(tong)號(hao)(hao)在成熟的(de)高鐵列控(kong)技術標準基礎上，自主研發(fa)(fa)的(de)基于無線(xian)(xian)通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)的(de)移動閉塞系(xi)統。該系(xi)統依據國內城(cheng)市軌道(dao)交通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)號(hao)(hao)系(xi)統“互聯(lian)互通(tong)(tong)(tong)(tong)(tong)”標準研發(fa)(fa)，為城(cheng)市軌道(dao)交通(tong)(tong)(tong)(tong)(tong)“互聯(lian)互通(tong)(tong)(tong)(tong)(tong)”量身定制，可(ke)實現列車最小90秒追蹤間隔。在原(yuan)有CBTC列車控(kong)制系(xi)統的(de)基礎上，該系(xi)統可(ke)實現列車不降速降級跨線(xian)(xian)運營至其它(ta)(ta)線(xian)(xian)路，并支持其它(ta)(ta)線(xian)(xian)路車輛進入本線(xian)(xian)運行(xing)，滿足城(cheng)市軌道(dao)交通(tong)(tong)(tong)(tong)(tong)聯(lian)通(tong)(tong)(tong)(tong)(tong)聯(lian)運需求，對節約旅客出行(xing)時(shi)間、提高城(cheng)市軌道(dao)交通(tong)(tong)(tong)(tong)(tong)運營效率具有重要意義。
信(xin)號(hao)(hao)系(xi)統是(shi)軌道(dao)交通(tong)的“大腦(nao)”，是(shi)控制車輛(liang)安全、高效(xiao)運(yun)(yun)行的神經(jing)中樞。重慶(qing)地(di)鐵5號(hao)(hao)線的順利開通(tong)，真(zhen)正解(jie)決了不同信(xin)號(hao)(hao)廠(chang)家車地(di)設備之間(jian)彼此(ci)“交流(liu)”的世界(jie)性技(ji)術難題，建(jian)立統一的信(xin)號(hao)(hao)系(xi)統互聯互通(tong)技(ji)術標準，為中國乃(nai)至(zhi)世界(jie)城市(shi)軌道(dao)交通(tong)的建(jian)設、運(yun)(yun)營、維護帶來一次歷史性變革。
據悉，中(zhong)國通(tong)號已中(zhong)標的長(chang)沙地鐵5號線也(ye)將繼(ji)續(xu)沿用CBTC互(hu)聯(lian)互(hu)通(tong)技術(shu)標準，我國城市(shi)軌道(dao)交(jiao)通(tong)互(hu)聯(lian)互(hu)通(tong)技術(shu)將得到進一步推廣應用。
