基于Matlab多台VP宽频带倾斜仪时域监控及频域PSD计算软件的研发
Development of Time-Domain Monitoring and Frequency-Domain PSD Calculation Software for Multiple VP Broadband Inclinometers Based on Matlab
摘要
Abstract
Based on the actual work requirements,this paper developed a time-domain monitoring and frequency-domain power spectrum density(PSD)calculation software for the VP broadband inclinometers on the Matlab platform.The software utilized the Matlab network functions to monitor the VP broadband inclinometer in real time to obtain data and display it visually.At the same time,it used the principle of the improved periodogram diagram method(Welch method)to automatically calculate the PSD of the daily observation data.It executed the time-domain monitoring and frequency-domain PSD calculation tasks concurrently in multiple threads through the Matlab parallel computing toolbox,without interfering with each other.After testing,the software could achieve real-time monitoring of multiple VP broadband inclinometers and promptly issue alarms for situations such as data breakage and out-of-range.This helped improve the quality of observational data at the station.Additionally,by automatically calculating the PSD of the observational data,it enabled station staff to analyze and summarize the normal background and interference characteristics of the observation data,thereby facilitating dynamic tracking and understanding of the background noise situation at the station.关键词
