Design And Implementation Of Software For Maintenance Machine Of Automatic Track Management System In Locomotive Depot

With the continue reform and rapid development of the railway transport industry in our country,locomotive depots rendered higher demand for the reliability of based equipment of railway signal. Besides,with the progress of railway signal technologies,the automation level of automatic track management system for locomotive depot becomes more and more high,technologies by used more and more advanced,and maintenance difficulty is increasing.Traditional maintenance mode and management of railway signal could not still meet the demand of safety production in locomotive depots.Thus,it will be imperative to study the application of railway signal microcomputer monitoring system in locomotive depots.The theme of this dissertation is to design and implementation of software of maintenance machine,which used in railway signal monitoring,of automatic track management system for locomotive depot.Taking a practical project as the background and combining with the actual demand,this thesis describes the development of the software system of maintenance machine by use of.NET platform,C# and multi-tire structure.First of all,this thesis briefly introduces railway signal microcomputer monitoring system,and analyzes the current application status in our country.Then,research topic of this thesis is given,and research meaning described.Secondly,the software system of maintenance machine is analyzed and designed, according to the objective and business functional requirements.In section of system analysis,the process modeling and data modeling of the software system of maintenance machine is established by using data flow diagram(DFD) and entity relationship diagram(ERD).In section of system overall design,the submodules are divided and their functions are designed.Meanwhile,the software system of maintenance machine is devised with the layered design.In detailedly designing section,the entity relationship diagrams of the software system of maintenance machine are transformed into relationship tables,and then adopted to SQL Server 2005,the thesis realizes the database of maintenance machine.After that,the thesis mainly discusses the detailed design of the business data processes of maintenance machine,also gives the sequence charts of these processes.Finally,the communication software of maintenance machine is implemented.At present,the system is evaluated on the simulation test platform in lab environment.The results indicated that the design has reached the expectation of research.
