Patent number: 11152126Abstract: This abnormality diagnosis system for diagnosing abnormalities in a plant is provided with: an abnormality diagnosis control unit which, with respect to an instrument parameter measured in a plant determined to have an indication of abnormality, predicts the development of the instrument parameter by extrapolation, and which generates an abnormality manifestation pattern that is a pattern of behavior of the instrument parameter after prediction; and a data storage unit which stores a plurality of abnormality model patterns PA, PB that are patterns of behavior of the instrument parameters corresponding to causes CA1, CA2, CB1, CB2 of plant abnormality. The abnormality diagnosis control unit makes a matching determination between the abnormality manifestation pattern that has been generated and the plurality of abnormality model patterns PA, PB stored in the data storage unit, and identifies, as the cause of the abnormality in the abnormality manifestation pattern.Type: GrantFiled: June 22, 2016Date of Patent: October 19, 2021Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Kenji Mashio, Takae Yamashita, Takashi Azuma, Susumu Shiizuka, Junichi Nishitani, Masafumi Utsumi, Jun Shibuya

Patent number: 11062273Abstract: A plant maintenance assisting system is provided with: an abnormality indication monitoring system; an abnormality diagnosis system; a maintenance plan creation system; a risk evaluation system; and a component management system. On the basis of risk information and abnormality diagnosis information that is a result of diagnosis by the abnormality diagnosis system, the risk evaluation system determines the need for maintenance work with respect to an abnormality indicating facility. In a case where it is determined that maintenance work with respect to the abnormality indicating facility is necessary, the maintenance plan creation system sets, in a maintenance plan, maintenance implementation timing of maintenance work with respect to a facility including the abnormality indicating facility. On the basis of component management information, the component management system determines whether a component can be procured at the maintenance implementation timing set by the maintenance plan creation system.Type: GrantFiled: March 7, 2016Date of Patent: July 13, 2021Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Takashi Azuma, Kenji Mashio, Takae Yamashita, Susumu Shiizuka, Junichi Nishitani, Masafumi Utsumi, Jun Shibuya
