Methods for gas leak detection and localization in populated areas using horizontal analysis

摘要

A procedure of Leak Detection and location of gasThe Method comprises: one or more Measurements from a gas concentration Measuring Instrument of gas (104) which is transported by a vehicle or a Mobile entity (102) that moves along at least a Rail Platform (106) arranged near one or more potential locations of gas leak; analysis of Automatic Horizontal Spatial ScaleMeasurements of gas concentration, and automatically determine if there's a gas leak is present in one or more of the locations of gas leak potential on the basis of the analysis of scale SpaceThe Automatic Horizontal; and provide an indication of leak in the locations of gas leak potential to an end user; characterized because of horizontal Spatial Scale Analysis respondsThe means of Peak widths of gas concentration Detection in a range between approximately 1 M and 50 m,And does not respond significantly to the means of Peak widths of gas concentration Detection outside the interval, where F (X) is the concentration of the gas as a function of position X,Where G (X, W) is a Core Function of a Gaussian Scale space is specified by the parameter W, where l (X, W) is a Convolution of F (X) and G (X, W),And where the Peaks of gas concentration, candidates are identified by the local Maximum Values of F (X, W) = - W (∂ 2L (X, W) / ∂ W2) with respect to X and W.
