Description

接触网在线监测系统及其方法 技术领域
本发明涉及电气化铁路接触网监测技术领域，具体涉及一种接触网在线监测系统及其方法。
背景技术
电气化铁路接触网沿铁路线露天布置，线长点多且无备用。随着电气化铁路快速发展，特别是高速电气化铁路路网规模的扩大，铁路部门对牵引供电系统的运行安全提出了更高的要求，接触网系统是高速铁路供电系统的重要组成部分，其基础设施养护面临保障安全、提高效率、降低成本的迫切需求。
接触网系统常年遭受风、霜、雨、雪等自然环境的侵蚀，以及高速运行受电弓的冲击和振动，其机械和电气的性能状态都在动态变化中，在机械作用力与电气损耗的双重作用下工作，机械和电气方面的故障构成了接触网系统的主要故障。
目前国内外接触网监测方法有，1)“人工巡视法”，该方法效率低、准确率差、反应速度慢，不但耗费大量的人力成本，而且受时间和天气条件限制，无法做到全天候测量。2)“专用检测设备法”，该方法是将设备安装在专用的轨道车辆上，如接触网检测车、综合检测车或接触网作业车等，由各主管部门负责调度，定期或不定期地对接触网进行检测，每两次检测时间较长，且检测过程中不能实时回传数 据，具有数据延迟现象，不能反映出现场实时情况。虽可获得相对准确的接触网检测数据，但该数据不具备时效性，线路周边环境随时间会有所变化，如风向、风力、气温、湿度等，所测量得的线缆张力、动态抬升量数据仅为测量时刻的情况，无法反映接触网实时动态情况。为最大程度保证接触网系统的安全运行，需要对接触网的工作状态及参数进行实时测量以排除安全隐患。
随着传感器和电子测量技术的飞速发展，接触网系统的状态监测技术也将有了较大的进步。采用物联网技术、先进的监测方法和现代化的监测设备对接触网系统进行实时监测是提高牵引供电系统安全可靠运行的保证，是实现电气化铁路智能状态监测和状态维修的重要手段。
