The invention discloses a settlement monitoring method for a high-speed magnetic suspension track, which comprises the following steps of: extracting a communication signal power value of an existing high-speed magnetic suspension millimeter wave communication system in the running process of a magnetic suspension train, drawing a receiving power curve of a line, and detecting the settlement condition of the track by analyzing the change of the receiving power curve. And a settlement value is extracted by utilizing the offset of the wave crest and the wave trough to realize track monitoring. The method is based on a double-path propagation model in wireless communication and depends on an existing high-speed magnetic suspension millimeter wave communication system, the problems that an existing track monitoring method is complex in operation, poor in real-time performance and the like are solved, the problems that a modern track monitoring technology is high in cost and many in environmental limitation are solved, the method can serve as a powerful supplement of an existing monitoring system, and the method is suitable for popularization and application. The method is suitable for high-speed magnetic suspension tracks, is also suitable for high-speed railways, common railways, even low-speed railways and other scenes needing track settlement monitoring, and has the advantages of being good in real-time performance, wide in measurement range and low in cost.

    本发明公开了一种高速磁悬浮轨道的沉降监测方法,首先在磁悬浮列车行驶过程中,提取现有高速磁悬浮毫米波通信系统的通信信号功率值,并绘制线路的接收功率曲线,再通过分析接收功率曲线的变化,检测轨道的沉降情况,并利用波峰和波谷的偏移提取沉降值,实现轨道监测。本发明的方法基于无线通信中的双径传播模型,并依托现有的高速磁悬浮毫米波通信系统,克服了现有轨道监测方法操作复杂、实时性差等问题,还解决了现代轨道监测技术成本高、环境限制多的难题,可作为现有监测系统的有力补充,适用于高速磁悬浮轨道,也适用于高速铁路、普通铁路,甚至低速铁路等需要轨道沉降监测的场景,具有实时性好、测量范围广且低成本的优点。
