Abstract
Addressing the pain points of traditional mine railway signaling systems such as redundant operational processes,complex routes,high risks of manual intervention,and numerous blind spots in safety monitoring,systematical study is carried out on the feasibility of upgrading the existing system,the intelligent upgrade pathways for railway signaling systems under complex terrain and harsh working conditions,and a turnout control system is introduced based on a fully electronic interlocking architecture.Computer control serves as the technical core of the system,with power electronics forming the foundational framework,while integrating hardware safety redundancy,real-time monitoring,and automatic fault localization technologies to achieve the electronic and modular upgrade of the original system.The upgraded system directly connects to outdoor signaling equipment such as turnouts,signals,and switch machines via power electronic units,enabling route selection and arrangement as well as the collection and management of statuses for on-site turnouts,signals,and tracks.While optimizing electrical circuits,it also provides standardized external interfaces,facilitating the integration of third-party control systems.The system not only offers robust technical support for the modernization of signaling equipment but also ensures safety,advancement,and reliability throughout the entire process.After upgrade,it is verified that the system's control interlocking cycle ranges from 150 to 300 ms under the dual-channel redundancy mechanism,with an average mean time to restore(MTTR)of not larger than 1 h across all aspects,and a 86%improvement in fault response efficiency.This solution successfully resolves the challenges of controlling and monitoring 29 turnouts and 127 routes in mine railways,validating the technical feasibility of a fully electronic interlocking system in unstructured mining scenarios.The research outcomes provide reusable technical frameworks and practical paradigms for the intelligent transformation of complex industrial transport scenarios in open-pit and underground mines,offering technical references for similar mine transport system upgrades.关键词
