Design And Realization Of Shanghai Metro Subway Damage Management Monitoring Information System

Shanghai Metro current operating mileages are more than420kilometers while877kilometers are expected to be completed by the end of2020which is a big challenge to maintenance party, so how to choose a right management mode is very important. The current maintenance work produces large amounts of information such as historical data, testing data and working processes. The relatively backward management mode already shows loopholes and shortcomings which should be replaced by the informatization management mode satisfying functions such as information storage and query, etc.Based on the current status of Shanghai Metro development, the contradictions of enterprise internal management and metro development status were pointed out and the method to resolve the current contradictions-information management was proposed in this paper. In the whole process of system development, Struts2was the core framework of presentation layer, Spring framework was the core framework of the business logic layer and persistence layer, Hibernate was database presistence solution while Spring Framework also played a role in management of Hibernate.The information management system was developed based on Object-Oriented Analysis and Design (OOAD) through the following steps including demand analysis (case study), object-oriented analysis system, object-oriented system design and object-oriented system implementation (system testing).1) First, both functional and non-functional demand analysis were made through function descriptions.2) Second, in the process of system analysis, the domain objects, object dependency and object properties were obtained through overall-analysis so as to draw the system domain model. Then, the working process in each case was obtained through detail-analysis.3) Third, in the process of System design, the static and dynamic models of background management platform and foreground display platform were designed and the realization of three big core functions in the system were stated in details.4) Finally, based on the object-oriented analysis and design, all the functions and demands had been achieved in the process of system implementation through the combined code and selected framework. With these steps, the information management of Shanghai Metro Defect management and monitoring was achieved.
