摘要：

Leak　detection　of　complex　pipe　network　of　hydraulic　system　is　the　difficulty.　A　software　is　developed　for　pipeline　network　leak　monitoring　system　with　distributed　optical　fiber　sensor　array　using　LabVIEW　and　FoxPro　database.　The　modulated　interference　signal　is　acquired　using　PXI-6133data-aequisition　card,　and　the　signal　is　denoised.　According　to　whether　there　is　zero　frequency　of　the　denoised　waveform　determines　whether　the　leaking　pipeline　and　conducting　alarm.　All　the　pipes　flow　and　pressure　changes　can　also　be　real-time　displayed.　All　the　allocation　data　and　flow　pressure　data　can　are　stored　in　real-time,　inquired　or　deleted　in　the　database.　The　system　is　proved　to　have　real-time　and　high　operability,　and　achieving　a　complex　hydraulic　pipe　network　leak　detection　of　intelligent　and　automated.
