<P>PROBLEM TO BE SOLVED: To automatically estimate a detectable blockage level. <P>SOLUTION: An impulse line blockage detection detectable level estimation system comprises: a blockage characteristic computing part 11; a deformation characteristic computing part 12; a pressure propagation model computing part 13; an evaluation determination part 14; a computing control part 15; and a display part 16. The blockage characteristic computing part 11 obtains flow characteristics of the blockage from a blockage level specified from the computing control part 15. The deformation characteristic computing part 12 obtains a deformation ratio for a pressure variation of an element constituting a pipe line system. The pressure propagation model computing part 13 obtains a pressure propagation model by using the obtained flow characteristics and deformation characteristics of the blockage. The evaluation determination part 14 evaluates pressure propagation characteristics of the obtained pressure propagation model and determines whether the specified blockage level can be detected by an applied impulse line blockage diagnosis method through comparison with a reference value. The computing control part 15 changes the blockage level to be specified to the blockage characteristics computing part 11 on the basis of the result of the evaluation determination in the evaluation determination part 14 and narrows down the borderline of detectability. <P>COPYRIGHT: (C)2013,JPO&INPIT |
