Abstract

The invention discloses a multi-dimensional data fusion equipment health assessment method and device and an operation and maintenance system. The device comprises a parameter selection unit, a data fusion unit and an evaluation and prediction unit. The system comprises an interaction module, the multi-dimensional data fusion equipment health assessment device and an operation and maintenance support module. The method comprises the following steps: selecting multi-dimensional associated data with relatively high association degree through a preset association parameter selection method, performing data fusion on the multi-dimensional associated data, calculating current health values of different evaluation levels of equipment according to data obtained after fusion calculation, and performing health value prediction of different evaluation levels on the equipment. According to the equipment health assessment method and device and the operation and maintenance system, the depth and accuracy of equipment health assessment are improved.

Description

technical field [0001] The invention relates to the field of multidimensional data fusion equipment health assessment, and relates to a multidimensional data fusion equipment health assessment method, device and operation and maintenance system. Background technique [0002] Equipment health assessment refers to the calculation and judgment of multi-dimensional parameters of equipment in the equipment operation and maintenance cycle to evaluate the health of equipment at different levels. In-depth and accurate equipment health assessment is conducive to the operation, repair and maintenance of equipment to maintain normal equipment functions. In order to prevent the degradation of equipment performance or reduce the probability of equipment failure, the technical management measures are carried out according to the predetermined plan or the corresponding technical conditions. Once the equipment fails, the operator needs to promptly notify the equipment maintenance personnel...
