摘要
针对传统矿山铁路信号系统存在的操作流程冗余、线路复杂、人工干预风险高、安全监控盲区多等痛点,研究了原有系统改造升级的可行性、复杂地形与恶劣工况下铁路信号系统的智能化升级路径,并引入基于全电子联锁架构的岔道控制系统。计算机控制作为系统技术核心,以电力电子技术搭建基础框架,并融入硬件安全冗余、实时监测、故障自动定位等技术,完成对原有系统的电子化、模块化升级。升级后的系统通过电力电子单元直接与室外的道岔、信号机及转辙机等信号设备相连接,实现进路选排以及现场道岔、信号、轨道等信号设备状态的采集和管理等,在优化电气线路的同时,并提供标准的对外接口,方便第三方的控制系统接入。系统不仅为信号设备的更新换代提供了坚实的技术支持,更确保了整个过程的安全、先进与可靠。系统改造升级后,经验证,在双通道冗余机制保障下,系统控制联锁周期为150~300 ms,系统各方面的平均恢复前时间MTTR≤1 h,故障响应效率提升86%。该方案成功解决了矿山铁路29组道岔、127条进路控制及监测难题,验证了全电子联锁系统在非结构化矿山场景中的技术可行性。研究成果为露天矿、井下矿等复杂工业运输场景的智能化改造提供了可复用的技术框架与实践范式,为同类矿山运输系统改造提供技术参考。
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,realtime 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.
