摘要:为了避免综合监控系统延伸线接入主线时功能调试对主线运营造成的影响,通过在主线停运期间用增设的临时中央级设备进行调试,在主线运营期间则恢复至原有中央级设备,当调试已完成且相应问题已基本整改时将延伸线正式接人主线。将其中措建的临时中央级设备、延伸线临时接人主线、开展平行调试、骨干网接人和设备升级等重要步骤进行归纳总结,并针对项目实施前的主线通信网络发生功能性损害的安全风险,以及项目实施过程中的系统数据库出现紊乱、临时设备上电后超载跳闸、非调试期间人员误操作等的安全
风险提出相应管控措施,进一步提高后续类似项目的施工效率和安全性。关键词:轨道交通;综合监控系统;平行调试;延伸线接入主线;风险管控

Abstract: In order to avoid the bad impact of function debugging on the main line when the integrated monitoring system exten sion line accesses the main line, additional temporary central-level equipment is used for parallel debugging during the main line outage , and the original central-level equipment is restored during the operation of the main line and the extension line is con nected to the main line when the debugging is completed and problems are solved. The important steps for setting up temporary central-level equipment, temporary access of the extension line to the main line, implementing parallel debugging, backbone network access as well as equipment upgrading are summarized in the paper. Countermeasures are proposed to respond to these curity risks, such as functional damage of the communication network for the main line before the implementation of the project, system database disorder, overload trip of the temporary equipment after power-on, wrong operation in the non-debugging peri-od during the implementation of the project

心1个),北延伸线有车站2座,东延伸线有车站13 座,分别通过光纤构成各自独立的双环通信骨干网,如图1、2所示。延伸线接人主线后将合并成统一的双环通信骨干网,并与主线共用控制中心,实行“中央级+ 车站级“两级管理模式。
综合监控系统延伸线接人主线的传统方法是:在主线停运期间直接将中央级服务器升级后进行调试,当日调试完成后再将中央级服务器恢复[3]。此方法的调试效率较低(升级和恢复的时间占总作业时间的 70%),安全风险较大。针对此问题,苏州轨道交通在2 号线延伸线接人主线时开创性地采用平行调试方法,即
