ANALYSIS DATA CREATION METHOD, NOISE FILTER, WATER LEAKAGE DETERMINATION METHOD, WATER LEAKAGE PLACE SPECIFICATION METHOD, AND VIBRATION DATA MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analysis data creation method, noise filter, water leakage determination method, water leakage place specification method and vibration data measurement method, capable of enhancing determination accuracy for water leakage detection.;SOLUTION: An analysis data creation method includes: a vibration data creation step of installing two vibration sensors 200 in at least two places, measuring vibration for a predetermined time by the installed vibration sensors 200, and acquiring vibration data; and a classification step of performing classification with at least one of a predetermined ratio of an acquired waveform to the number of pieces of vibration data and a predetermined ratio of the acquired waveform to the size of vibration. Then, the analysis data creation method obtains first group of analysis data whose vibration level is larger than a first threshold, and a second group of analysis data whose vibration level is smaller than a second threshold.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
