Abstract

The invention relates to a method for extracting and judging operation data stability of ship electromechanical equipment. The method comprises the following steps: acquiring ship electromechanical equipment data, preliminarily judging data stability, calculating the minimal length of a stable inspection data segment, judging data stability point by point, correcting the stability inspection result as well as storing and outputting results. The defects that true stable data is difficult to judge simply by the statistic method and large-range judgment error occurs in the prior art are overcome.Through the judgment method, the stable operation data of the electromechanical equipment is extracted, accuracy and reliability of modeling, evaluation and even optimized decision can be improved, and important significance in analysis and research of ship data is achieved.

Description

technical field [0001] The invention relates to the technical field of analysis of operation data of electromechanical equipment of ships, in particular to a method for extracting and distinguishing the stability of operation data of electromechanical equipment of ships. Background technique [0002] In order to make the ship sail more economically, safely and reliably under various possible working conditions, and to construct the health model of the main engine diesel engine and the power station diesel engine, it is necessary to obtain the stable operation data of the ship-related electromechanical equipment, so as to provide data for the modeling and analysis of various equipment. premise. During the ship's voyage, affected by the surrounding environmental factors such as wind, waves, swells and other environmental factors, the ship's electromechanical equipment is almost always in a frequently changing operating state. It is more difficult to extract the stable operati...
