Design And Implementation Of Simulation System For Gas Valve Electronic Dynamic Adjustor

This thesis to discuss the development work on the JingLi company gas valve’selectronic dynamic adjustor’s simulation software based on the methods and techniques of software engineering.The software is applied to provide flexible,highly efficient and low-cost tools to support these products development.This thesis systematically discusses the development works in requirements analysis,software design,programming and tests in accordance with the specific demands on thegas valve electronic dynamic adjustor development.In requirements analysis it establishes main functions of the system including basic information management,the gas valve electronic dynamic adjustorcomponents modeling,the devicedynamicssimulation and some assistant functions.For each requirement its desired data processing demands and computational tasks are discussed with the use case models.In the work of software design,this thesis establishes the software architecture and the related design scheme,including main object data structures,database models,representative algorithm processing frameworks and some example database table structures.In the work of implementation,this system runs on the platform of Windows operating system on the application server and is programmed with C++.The system database is SQL Server.Some programs are briefly described together with the system test methods and results.This gas valve electronic dynamic adjustorsimulation management system has now been finished with its tests and deployment.During its applications it has provided design support to multiple gas valve electronic dynamic adjustor designs with significant effects in the products’ design assessment and achievespositive effects in lowering the cost and raising the efficiency.
