摘要: 介绍一种监测地质灾害的辅助方法,使用自主研制的次声波实时监测预警仪器采集次声波信号,再传输至上位机软件系统进行数据显示、储存、查询等操作。在此基础上,将数据导出,用Matlab语言对信号进行小波去噪后,再利用离散傅里叶变换获取信号的频谱图。通过对频谱图进行研究、分析、获取次声波的相关信息,从而对地质灾害进行监测与预警。经测试,该系统具有运行稳定、数据准确、监测精度高和实时性强的优点。

Abstract: This paper introduces a kind of auxiliary method of monitoring the geological disasters,which uses self-developed infrasonic wave to real-time monitor and warn instrument to collect device signal,then transmits it to a PC software system for data displaying,storing,and inquiring.On this basis and after the data is derived,Matlab language is used to analyze and filter the signal wavelet,and then the discrete Fourier transform is adopted to obtain the signal spectrum diagram.Through the analysis and research on the spectrum diagram,the related information of device were accessed,thus to monitor and warn the geological hazards.By tests,it is found that the system has some advantages as stable running,accurate data,high precise monitoring,and good response.
