Abstract:
A method wherein a plurality of pipelines which are laid under the ground or through a structure at specific intervals are employed in their entirety for a synthetic danger predicting alarm sensor, characterized in that both end portions of each of said plurality of pipelines are fitted with synthetic sensors, each of said synthetic sensors are provided with detector portions for taking measurements in connection with at least sound, radiation, heat, mechanical stain, electricity, magnetism and vibration, and wherein signals of abnormality information which are given for the external or internal portion of each pipeline laid under the ground or through a structure, or the interior of a geologic stratum or that of the structure as a result of variation of measuring signals from their normal condition are simultaneously measured by means of the detector portions of said sensors, and means for analyzing said signals to predict disastrous trouble at one or ones of specific intervals of the plurality of pipelines.
