Abstract:
Sequential probability ratio test(SPRT) is put forward to detect and locate small leakage.Unitary new information sequence generated after Kalman Filter processing can be used to input sequence of SPRT to satisfy the requests.Methods of judging and locating leakage are analysed.At last,Kalman Filter and SPRT algorithms are realized with virtual instrument software,LabVIEW.The programming modules can be directly used in the existing pipeline leakage real-time detecting system.The experiments show that the design of rational and effective procedures for leakage of less than 3% of the small leak is also very effective and controls the positioning accuracy within 2.5%.
