基于盲源分离的管道声波信号分析及处理方法探究

摘要

There are many indeterminate signal source and interference factors when analysis the pipeline acoustic signal.In the practical application,the test result is always not very accurate because of practical environment influences.Based on the analysis of he separated signal time domain and frequency domain signal,it showed that the separated signal had a great practicality,it provides new research methods and ideas for the research of pipeline early warning technology.%　　由于对管道声波信号进行分析时，会有许多不确定的信号源干扰因素，在实际生产应用中更是受到现实环境制约影响从而导致检测结果并不准确。本文通过对分离信号进行了时域和频域信号分析，表明分离信号具有极大的实用性，为管道预警技术的研究提供了新的研究方法和途径。
