Equipment health management system and database modeling method thereof

Abstract

The invention discloses an equipment health management system and a database modeling method thereof, and belongs to the technical field of management systems. The equipment health management system comprises a CBM equipment health management subsystem, an equipment health information visualization system and an expert system, and further comprises a space-grid-based database including a space grid node data packet composed of space grids and grid nodes, wherein relative space coordinates of nodes and activation time of the nodes are stored in the space grid node data packet. The system and the method provided by the invention have the advantages that firstly, an equipment management space is subjected to space grid division, so that grid data can be stored in a distributed manner, grid parallel computing is facilitated, and data processing efficiency is improved; secondly, the traditional journal recording mode based on a time line is converted into a space-based journal recording mode, so that journal recording modes are enriched; thirdly, three-dimensional visualization processing is performed on equipment health state information corresponding to the space grids.

Description

technical field [0001] The invention relates to an equipment health management system, in particular to an equipment health management system and a database modeling method thereof, belonging to the technical field of equipment management. Background technique [0002] Traditional equipment management methods focus on fault handling and static maintenance, that is, after a fault occurs, use fault diagnosis or shutdown and disassembly maintenance to restore the equipment in stages and maintain the overall health of the equipment. The traditional equipment management method has a single management method, and regular fault diagnosis or fault maintenance has a certain impact on production, which is inefficient and cannot achieve the purpose of maximizing equipment utilization. [0003] In order to promote the development and progress of the equipment management model, many enterprises in my country have carried out maintenance research based on condition maintenance (CBM), and ...
