摘要:
上海轨道交通2号线是路网中重要的骨干线路，其一期段开通运营至今已达20年，存在设备老化和损耗严重等隐患。升级后的2号线信号系统全线采用新增CBTC作为主用信号系统，既有TBTC作为降级系统的方案，提升了信号系统的可靠性和可用性；技术方案符合信号系统技术的发展方向，满足长期的运营服务水平需要，与其在上海轨道交通线网中的重要性相匹配；对既有运营影响最小，实施风险可控。
Abstracts:
Shanghai Rail Transit Line 2 is an important backbone line in the road network, of which the first phase section has been operating for almost 20 years, and there are serious hidden dangers from equipment aging and wear and tear. The upgraded line 2 signaling system adopts the new CBTC as the main signaling system for the whole line. With the existing TBTC as the solution for downgrading, the reliability and availability of the signaling system are improved. The technical scheme conforms to the development direction of the signaling system technology, meeting the long\|term operational service level needs, matching its importance in the Shanghai rail transit network. The impact on the existing operation is limited to the least and the implementation risk can be controlled.
