摘要:
在轨道交通信号系统升级改造施工调试期间，新旧系统需进行多次倒接。结合上海轨道交通5号线工程应用实例，详细介绍不同倒接方式的设计原理、施工方案及倒接操作方法。对不同倒接方式的适用范围、经济性、可靠性及可维护性进行分析比较，供其他同类工程参考借鉴。
Abstracts:
During the construction and commissioning of the rail transit signal system upgrading, multiple reverse connections between the new and old systems are required. Combined with the practical application of reverse connection on Shanghai metro Line 5, the design principle, construction scheme and operation method of different reverse connection methods are introduced in detail. The application range, economy, reliability and maintainability of different reverse connectionsare analyzed and compared, providing reference for projects in the same category.
