Development of Pipeline Leak Detection System based on LabVIEW

摘要

This paper developed a pipeline leak detection system based on virtual instrument LabVIEW and described the system principle, composition structure and development progress in detail. The pipeline leak detection system acquired pressure and flow at two ends of the pipeline real time, analyzed data by wavelet analysis functions offered by LabVIEW, detected leak through flow changes and located leak by negative pressure wave method. This system has the characteristics of perfect functions, friendly interface, convenient operation and great practicality.
