METHOD FOR DETECTING LEAKAGE ZONE IN MAIN PIPELINES Russian patent published in 2002 - IPC

Abstract RU 2190152 C1

FIELD: measuring technique, possibly current monitoring of fluid tightness of main pipelines. SUBSTANCE: method comprises steps of registration time moment of arrival of two lowered-pressure waves formed at time moment of local rupture or damage of pipeline to ends of said monitored pipeline; detecting time difference of arrival of those waves and determining leakage position; generating high frequency oscillations at time moment of local rupture or damage of pipeline; manipulating said oscillation by phase by means of modulating code containing data related to number of damaged piece of pipeline and leakage position in order to form phase-manipulated alarm signal; amplifying received signal and irradiating it to atmosphere; receiving alarm phase- manipulated signal in control station by means of three antennas arranged along one line parallel to pipeline in the form of straight line piece; placing in center of said line receiving antenna of measuring channel common for receiving antennas of two direction finding channels arranged in azimuthal plane in order to create in that plane two measuring bases d and 2d satisfying to given inequality: , where λ - wave length. Lower base d provides rough but unambiguous scale for reading angle value. Larger base 2d provides accurate but ambiguous scale for reading angle value. Received signals are converted by frequency; voltages of first intermediate frequency are extracted; voltage of first intermediate frequency of measuring channel is again converted by frequency; voltage of second intermediate frequency is extracted and it is multiplied to voltage of first intermediate frequency of direction finding channels; harmonic oscillations are extracted out of received voltages at frequency of second heterodyne and at keeping phase relations; phase difference between harmonic oscillations and voltage of second heterodyne is measured in order to evaluate azimuth value of damaged portion of pipeline. EFFECT: enlarged functional possibilities of method due to transmitting alarm signal related to leakage position by radio channel. 4 cl, 10 dwg
