The invention discloses an overhead line system online monitoring, hidden danger and fault intelligent judgment and early warning system and belongs to the related technical field of electrified railways. The system comprises an overhead line system real-time parameter acquisition unit, a real-time data collection, transmission and arrangement unit and a calculation and analysis center. According to the system, various parameters of an anchor section and change conditions of the anchor section under various fault conditions are obtained by utilizing relevance among all parts in the anchor section and installing various detection devices at related positions of the anchor section, the big data analysis and artificial intelligence technology is used to analyze and classify the change data caused by the faults, the threshold value of the data change caused by the faults is summarized, the fault threshold value is used to discriminate real-time monitoring data, and the real-time discrimination and alarm of a fault hidden danger occurring in the operation process are realized, the situation that the working state of the overhead line system is regularly detected through a manual inspection mode for a long time is changed, the labor cost is saved, and the detection efficiency is improved.

    本发明公开了电气化铁路相关技术领域的一种接触网在线监测及隐患、故障智能判别预警系统。系统包括接触网系统实时参数采集单元,实时数据汇集、传输、整理单元和计算分析中心,本发明利用一个锚段内各部分之间的关联性,通过在锚段相关位置安装各种检测设备,获取锚段各类参数及其在各种故障情况下的变化情况,运用大数据分析和人工智能技术,对这种故障引起的变化数据进行分析归类,总结出故障引起数据变化的阈值,利用该故障阈值判别实时监测数据,实现对运行过程中出现的故障隐患的实时判别并报警,改变了长期以来通过人工巡检方式定期检测接触网的工作状态,节约了人力成本,提高了检测的效率。
