Abstract

The invention relates to a Multi-source information-based ship residual life prediction method and system, and solves the problems that an existing ship residual life prediction method is low in reliability and poor in prediction precision. The method comprises the following steps: collecting a system output signal vector of a ship sensor measurement sample, determining a system initial state and an initial parameter, and calculating a system state according to the system initial state and the initial parameter; according to the system output signal vector and the system state, calculating an optimal state estimation value of a sampling moment and each past sampling moment; estimating the state value of each future sampling moment according to the optimal state estimation values of the sampling moment and each past sampling moment; and comparing the state value at each future sampling moment with a threshold value to predict the residual life of the ship.

Description

technical field [0001] The invention relates to the technical field of ship life prediction, in particular to a ship remaining life prediction method based on multi-source information. Background technique [0002] In recent years, with the rapid development of electronics, information and other technologies, the remaining service life prediction is used as the basis for the formulation of equipment maintenance strategies and is one of the important links in prediction and health management. Accurately predicting the remaining service life can provide comprehensive, accurate and effective information for the formulation of equipment maintenance strategies, avoid equipment failure, reduce losses caused by failure, and provide guarantee for safe and reliable operation of equipment. [0003] There are dynamic systems with multiple independent and unrelated sensors in the shipbuilding industry. There is an implicit performance degradation process in this type of system, but ther...
