基于毫米波通信信号的高速磁浮轨道沉降实时监测方法
Real-Time Track Settlement Monitoring Method for High-Speed Maglev Based on Millimeter-Wave Communication Signals
摘要
Abstract
To address the limitations of conventional track settlement monitoring methods,such as poor real-time per-formance and high cost,a track settlement monitoring method based on cross-correlation analysis of millimeter-wave com-munication signals is proposed.The method exploits a millimeter-wave train-to-ground communication system to achieve track condition sensing while supporting high-data-rate transmission,extending the capability of communication signals for environment-assisted sensing.Compared with traditional approaches relying on manual inspection or dedicated equipment,the proposed method offers flexible deployment,low cost,and strong real-time performance.During high-speed maglev train operation,the received communication signal is formed by the interference between the line-of-sight and reflected paths,and its power level is highly sensitive to track settlement variations.Settlement-induced changes in the reflected path length and phase relationship lead to a shift in the interference pattern,providing a physical basis for settlement inversion.Path loss compensation and zero-phase filtering are applied to recover the true received power and suppress noise without signal distortion,while an adaptive windowing strategy is employed to enhance the stability of interference shift estimation.Cross-correlation analysis is then used to extract the relative interference shift,and a linear mapping between the interfer-ence shift and the track settlement is established for high-precision estimation.Experimental results show that,within a set-tlement range of 1～10 cm,the monitoring error is within±0.5 cm,with coefficients of determination(R2)exceeding 0.94.The proposed method provides a low-cost and high-resolution solution for dynamic track settlement monitoring in high-speed maglev systems.关键词
