Research and implementation of condition-based maintenance system for stack crane in automatic storage and retrieval system

Abstract

Aiming at solving the problem of excess or lack of maintenance which exists in traditional maintenance of stack crane in automatic storage and retrieval system, the stack-crane monitor and diagnostic system (SCMDS) based on the component module has been proposed, using the SCMDS as a research object, and utilizing the open-system architecture for condition-based maintenance (OSACBM) model and component technology theory for reference. First, this paper details the internal structure, functional modules, and interactive interface of the generic component module with the reconfigurable and scalable features in SCMDS. Second, it puts forward the six layers whole project of SCMDS which constituted by single and nested components. Finally, using the fault tree analysis model which established on the physical characteristics of the stack crane as an example, it describes the specific implementation of a single component and also provides the theoretical basis for application.
