Abstract

The invention provides a ship machinery health state assessment method and system. The system comprises an initialization information configuration module, a data preprocessing module, a sub-model health value calculation module, a node comprehensive health value calculation module, a health value prediction module, an auxiliary decision-making module, a database module, an initialization information configuration module and a dynamic threshold calculation module. Initialized information configuration, including configuration of channel value signals of data, configuration of each module and the like, is performed before real ship application; ship cabin data is collected in real time, and the ship cabin data is preprocessed and stored; relevant data are extracted to calculate and store sub-model health values; a corresponding sub-model calculation result is extracted, and a node comprehensive health value is calculated; and the future development trend is predicted according to the historical health value of the node, and if the fault is predicted to occur, the auxiliary decision module is automatically triggered to give warning and maintenance suggestions to marine engineers, so that the occurrence of major faults is avoided.

Description

technical field [0001] The present invention relates to the technical field of monitoring the health state of ship machinery, in particular, to a method and system for evaluating the health state of ship machinery. Background technique [0002] Under the background of "Industry 4.0" and "Made in China 2025", intelligent ships and unmanned ships have become the focus of the development of today's shipbuilding and ship operating industries. Engine room intelligence is the core content of ship intelligence. Among them, the important systems and equipment health status assessment and remaining life prediction technology research of ship power plant can reasonably arrange the maintenance of engine room equipment through the analysis and research of equipment operation information. Discovering potential failure factors of equipment, and automatically performing fault finding and troubleshooting are the requirements of technological development and social needs in the new era, and ...
