Title:
SHIP MAIN ENGINE MONITORING METHOD, MAIN ENGINE MONITORING SYSTEM, MAIN ENGINE STATE PREDICTION SYSTEM, AND OPERATION STATUS PREDICTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/235688
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a ship main engine monitoring method capable of monitoring a main engine state with an accuracy comparable to actual measurements, without requiring much actual measurement equipment; a main engine monitoring system; a main engine state prediction system; and an operation status prediction system. In the present invention, a primary measurement value and a setting value pertaining to the operation of a main engine (10) of a ship (A), the setting value being a main engine state parameter serving as an intra-model variable, are applied to a main engine virtual model (40) based on a combination of physical models representing a response for each constituent element of the main engine (10). Calculations are performed with the main engine virtual model (40) to monitor the main engine state of the main engine (10). At least one of the main engine states obtained as a calculation result and the main engine state parameter are used to change the model parameter serving as the intra-model variable and update the main engine virtual model (40).
