Design And Implementation Of Metro Vehicle Maintenance Management System

With the increasing number of population in our country, the traffic of city is becoming more and more crowded. In order to reduce the time spent in traffic congestion, many people choose to travel in the metro. Metro is not only convenient and fast, and there will be no congestion situation, which is the biggest advantage of the metro. Because more and more people take metro, how to ensure the safety and stability of metro has become a very important work. This paper designs and implements a metro vehicle maintenance management system, which can manage the inspection information and maintenance information of metro vehicles, which can improve the efficiency and quality of maintenance work.(1) This paper introduces the background and significance of the system, and researches the actual maintenance management. A lot of problems have been found in the research process. In order to solve these problems, this paper puts forward the development of metro vehicle maintenance management system to manage the maintenance work.(2) This paper introduces the system requirement analysis, feasibility analysis, use case analysis and system development and operation environment.(3) This paper introduces the design and implementation process of the system. In introducing the design process of the system, the paper first introduces the principle that should be followed in the design, and then introduces the structure, process, function and database of the system. The working process of the system is based on the actual work process, and the system can manage the whole process of maintenance and repair work. The system ensures that the user can use the system more quickly. Architecture of this system is five layers B/S structure, including the UI layer, business logic layer, entity object layer, database access layer and database layer. Through this design can ensure the architecture of the system is more reasonable, and can improve the efficiency of operation. In order to better design the database system, this paper determines the entities and relations between them of the system firstly, and then design the structure of the main database table. On the function, the system can manage information during routine maintenance, including failure information, maintenance program information, service information, parts inventory information, etc.In the design process, this paper uses the method of UML modeling, using the flow chart, sequence diagram and E-R diagram and so on to describe the design content. When introducing the realization of the management system of the subway, it introduces the realization process of the function mainly through the interface, the realization process and the realization code. In the development process, the system uses the.NET development platform, using C # as the development language. In order to enhance the user experience, the system uses AJAX technology to achieve asynchronous refresh.(4) This paper introduces the testing process of the system. The test shows that the function of the system is reasonable, the operation is stable, and the work needs of metro vehicle maintenance management are satisfied.
