Research on equipment maintenance data recording method based on E-R diagram model

摘要

For existing equipment maintenance records, normative is not so strong. Worse more, the text-based description always makes post data mining impossible or difficult. In order to realize the equipment maintenance information, this paper imports the basic idea of E-R (Entity-Relation) graph model into numbering separate parts and assembly relations. The Roche mechanical turbocharger was taken as an example to describe how to operate the numbering and display the powerful potential in the post data-mining process.
