| Abstract: | To solve the problem of pipeline leak detection and meet the demand of student＇s learning, an experimental system of pipeline leak detection based on negative pressure wave and flow is established in the laboratory. Advantecb DAQ board PCI-1710HG is used to acquire pressure and flow flux, wavelet transform is utilized to analyze the test data the software of the monitoring system is developed by National Instruments graphical programming language LabVIEW. It can detect and locate pipeline leak point in time. Finally, a set of testing results is provided. |
