Embodiment Construction

[0026] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0027] Too many health characterization parameters often lead to problems such as high test cost, large information redundancy, and strong background noise; while too few health characterization parameters are likely to cause problems such as lack of status information, incompleteness and inability to meet the information requirements of equipment health management. . In particular, in the design stage of equipment, physical models are lacking, knowledge information is limited, uncertainty and ambiguity are strong, and it is difficult to determine health characterization parameters through methods based on experiments and models. The method provided by...

Abstract

The present invention relates to a method for determining health characterizing parameters of an electromechanical device. The method is characterized by comprising a first step of performing at least one of structure decomposition, function decomposition and fault decomposition on the elecromechanical device so as to decompose the electromechanical device into sets of multiple levels of parts; a second step of establishing parameters, a sensor and setting position of the sensor, a fault mode, and a many-to-many mapping relationship of fault effects for each part obtained through decomposition; and a third step of according to parameters measured by the sensor, determining the health state of the electromechanical device through the many-to-many mapping relationship, when it is detected that the health state of the electromechanical device and actual health state of the elecromechanical device have deviation, if the deviation is greater than a preset value, performing the first step to the third step again till the deviation falls into a set range, so as to determine the health characterizing parameters of the electromechanical device.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to the technical field of engineering reliability and safety. Background technique [0002] Electromechanical equipment occupies an extremely important position and role in ships, and is responsible for ship propulsion and power supply. Without an electromechanical system that is in a healthy state and meets the requirements of ship operation, the ship cannot complete its mission. Therefore, the health status of electromechanical equipment is an important indicator to measure its capabilities. How to evaluate the health status of electromechanical equipment must first solve the problem of measuring the health status. According to the composition, function and the characteristics of the task of the ship's electromechanical equipment, on the basis of the sensor information collection parameters, the construction of its characterization parameter system is realized in stages.
