在城市轨道交通信号系统改造调试期间，对新设信号系统的调试不能影响既有信号系统的正常运行。通过对城市轨道交通运营需求的分析，将新设信号系统放在非运营时段进行调试。在运营时段和非运营时段，分别由既有信号系统和新设信号系统控制室外设备。针对调试期间，两套系统分时复用共用室外设备的问题，设计了一种分时控制的倒切电路，并给出了倒切电路的工作流程。倒切电路具有两种控制权限，由转极电路、倒切电路、表示电路组成。该倒切电路具有倒切快速、操作方便、显示清晰、安全可靠等优点。
在城市軌道交通信號繫統改造調試期間，對新設信號繫統的調試不能影響既有信號繫統的正常運行。通過對城市軌道交通運營需求的分析，將新設信號繫統放在非運營時段進行調試。在運營時段和非運營時段，分彆由既有信號繫統和新設信號繫統控製室外設備。針對調試期間，兩套繫統分時複用共用室外設備的問題，設計瞭一種分時控製的倒切電路，併給齣瞭倒切電路的工作流程。倒切電路具有兩種控製權限，由轉極電路、倒切電路、錶示電路組成。該倒切電路具有倒切快速、操作方便、顯示清晰、安全可靠等優點。

During the period of transformation and commissioning of the signal system of urban rail transit, the debugging of the new signal system should not affect the normal operation of the existing signal system. For this reason, by analysis on operational requirement of urban rail transit, the new signal system should be debugged during non-operating period. The existing signal system controls the outdoor equipments during operation period, while the new signal system controls the outdoor equipments during non-operation period. In order that the two systems could share the same outdoor equipment with the time division multiplex technology during the period of commissioning, a kind of quick switch circuit based on time-sharing control technology was designed, and the workflow of the quick switch circuit was given in this paper. The whole quick switch circuit has two kinds of control permissions, being made up of pole-turn circuit, switch circuit and indication circuit. Especially, this quick switch circuit has advantages of fast switching, convenient operating, clear displaying, higher safety and reliability and so on.
