| The RC450 hydraulic machine running assistance system is developed under the goal of supporting the user to operate the equipment in complicated production tasks correctly and effectively, in particular to make the correct numerical control and optimize program before performing the operation through the hardware status and its failure events simulation in order to raise the quality's assistance in the real production.The thesis states in detail this software's requirement analysis for its functions, software design and programming implementation. The functions implemented by this software include the functions of the equipment operation and running status simulation, various failure events simulation adapt to its operations and the numeric control programming aid. These functions are analyzed with the related use-case models. The software design scheme is established around this software analysis which is in the layered organization. Among the layers the user interface layer implements the interactive information processing and simulation outputs displaying. The model management layer implements the hydraulic equipments operating models' maintenance which covers the hydraulic device model objects, hydraulic loop model objects, hydraulic equipment model objects on basis of the simulation project object. These objects compose the simulation task with the object classes inheritance relationships and association relationships. The data management layer implements the basic and dynamic data processing within the universal framework of the relational database model. This thesis presents the objects internal data structure, class diagrams and the main task processing program frameworks.This software is implemented with C++ and its integration with database servers through the standard SQL programming interfaces. Now this software has completed all standard processing specification tests on the main functions and comparatively well reached the expected effects. |
