Design And Implementation Of Shanghai Subway Equipment Safety Operation Management System

This thesis discusses software development of Shanghai subway equipment safety operation management information system, including systematical discussion of its demand analysis, software design and implementation.First, it generally describes the system’s developing background and related technology. From the view of users, it analyzes and discusses the company’s subway equipment running management system function features, input/output data processing requirement. It also analyzes the system’s developing goal and main functions, including equipment basic information management, equipment online running status management and equipment breakdown management, and builds corresponding user case modules which are the results of demand analysis. Then, based on demand analysis, it discusses the system’s software design scenario, including software architecture, outlined design, database design and main modules’ internal processing flow and algorithm. It also briefly discusses corresponding design scenarios’main consideration factors and advantages, as foundation of programming implementation. On the basis of software design scenario, it discusses main programming, running information examples and system testing, and gives summary at last.This system’s developing main programming tools include Java, Oracle database and data distribution service middleware - DDS Openslice. Based on Java programming, the system can conduct efficient task distribution and multi-task processing; based on Oracle database, it realizes large-scale data storage management and transactional processing; based on DDS middleware, it achieves distributed access management to data flows. The system has passed trial test and reaches table running status, and meets the planning developing goals.
