RESIDUAL SERVICE LIFE ASSESSMENT METHOD, RESIDUAL SERVICE LIFE ASSESSMENT DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To simply and nondestructively assess residual service life of inspection objects for use in receiving and transforming facilities, thereby improving the reliability.;SOLUTION: A residual service life assessment apparatus 100 for assessing the residual service life of inspection objects related to receiving and transforming facilities includes: a reference data storage unit 25 which stores reference data determined by a reflected light from a brand-new one of inspection objects irradiated with inspection light; a service life threshold storage unit 23 which stores service life threshold determined by service life factors of the inspection object; an optical measurement control unit 6 which acquires measurement data determined by the reflected light from a deteriorated one of the inspection objects irradiated with the inspection light from a probe 1 and a spectroscope 2; a deterioration level calculation unit 11 which calculates the deterioration level of the deteriorated one of the inspection objects based on the measurement data and the reference data; and a residual service life assessment unit 13 which predicts secular change in the deterioration level, defines a period when the predicted value of the future deterioration level accords with the service life threshold, as the service life of the deteriorated one of the inspection objects, and calculates a difference between the service life and the present age of the deteriorated one of the inspection objects as the residual service life of the deteriorated one of the inspection objects.;COPYRIGHT: (C)2012,JPO&INPIT
