Design And Implementation Of Locomotive Working System

As one of the three major systems for train operating-diagram, locomotive working system offers basic motive force for organization work of train operation. With the enhancement of railway information level of our country, it is urgent to construct a locomotive working system based on train operating-diagram drawing system, thus satisfying the rapid development of our railway industry, bringing the train operating-diagram into a full play and maximize the utilization of computer information sharing.This thesis develops a locomotive system by adopting RUP method (Rational Unified Process), and explains in detail how to realize the analysis, design and implementation of the system with the help of RUP. Meanwhile, this thesis also introduces various functional modules of the locomotive system, as well as some algorithmic problems arising from the development process and a corresponding method to solve these problems. The system developed in this thesis, by adopting Rational Rose Tool, designs diagrams such as case diagram, class diagram, sequence diagram, package diagram and data model diagram. Finally implementation of the system is completed by using VC++.The thesis is organized as follows: Chapter one introduces the current situation of the domestic research on locomotive working system, and the significances of the present study. Chapter two serves as a theoretical foundation for introducing locomotive working system and corresponding arithmetic problems as well as basic knowledge about UML (Unified Modeling Language). Chapter three gives an analysis of the requirements of the system by adopting UML modeling technology, and at the same time introduces an idea of designing the overall scheme of the system. Chapter four designs a database and class for the system; sets up systematic class diagram, sequence diagram, and package diagram by using UML; and constructs data model diagram by using Rational Rose. Chapter five introduces various methods to solve the problems arising from developing process and the...
