METHOD FOR REMOTE DIAGNOSTICS OF STATE OF LINEAR PART OF UNDERGROUND MAIN PIPELINES Russian patent published in 2015 - IPC F17D5/02 G01V8/00 

FIELD: measurement equipment.

SUBSTANCE: method is intended for solution of a task of remote detection of precursors of emergency situations on underground main pipelines. The method is implemented by acquisition and analysis of images as per reflected and proper radiations of the underlying surface of the pipeline running route. Before the beginning of the route survey, there shaped are simulators of designated precursors with storage of their coordinates in a flight navigation device of a flying carrier. Images obtained during the flight are transformed to space of solutions by means of matched filters and by using as thresholds of taking decisions of output signals of filters from images of the corresponding simulators. At the same time, correlation functions of the received images are determined to calculate the number of false decisions and as per this number and the shaped space of solutions there determined is availability on the test route of precursors of emergency situations of the corresponding type.

EFFECT: improving reliability of detection, reducing the volume of information transmitted via a communication channel.
