我国城市轨道交通信号系统发展方向探讨

Discussion on the Development Direction of Urban Rail Transit Signaling Systems in China

中国的城市轨道交通信号系统具有后发优势,除了上世纪九十年代早期建设的几条地铁线路的信号系统外,几乎全部采用CBTC(基于通信的列车控制)系统,实现了移动闭塞,这是几代轨道交通信号人梦寐以求目标。随着北京燕房线自主化的基于CBTC的FAO(全自动运行)列车控制系统开通以后,多家国内信号供应商拥有了自主化的FAO产品,并得到了工程验证。中国城市轨道交通信号系统的发展进入了“无人(领跑)区”,我们必须自己回答,我国城市轨道交通信号系统向何处去。

China's urban rail transit signaling systems possess the distinct advantage of later development.Nearly all existing metro lines adopt CBTC(communication-based train control)system and has achieved moving block except for few lines constructed in early 1990s,which is a long-awaited goal for several generations of rail transit signal professionals.Following the commissioning of Beijing Subway Yanfang Line FAO(fully automatic operation)train control system based on CBTC,numerous Chinese signaling system suppliers have independently developed their FAO products and completed engineering validation.The development of China urban rail transit signaling systems is now entering the'unmanned(leadership)'phase.The question of the future direction for China urban rail transit signaling systems must be addressed by ourselves independently.
