Discussion on the Function and Interface Schemes for Interlocking System of Multi-level Railway Network Junction Station
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 10
Abstract
Objective In the multi-level road network, junction stations of lines with different signal systems face quite a number of challenges. In order to meet the new demands of multi-network interoperation, it is necessary to conduct in-depth research and propose interlocking functions and interface configuration solutions for junction stations. Method By comparing the differences between interlocking systems under CBTC and CTCS-2 signal systems, signal control function, construction and operation demands are analyzed in detail, and functional requirements of the junction station interlocking system are clarified. On this basis, the interface objects and interface contents of the interlocking system are further analyzed. Finally, a configuration scheme for the interlocking interface of the junction station is constructed. Result & Conclusion The junction station interlocking system not only needs to complete the basic route safety protection function, but is also able to adapt to the requirements of various signal systems for basic information provision, capable of mobile blocking adaptability, as well as comprehensive functions such as section block combination, platform door control, over lap section protection, automatic return route processing, flexible operation adjustment and adaptation. At the same time, the junction station interlocking system should support multi-channel interfaces such as signal safety data network, wired ring network, wireless network, relay, etc. to ensure the compatibility and reliability of the system.
