| With the large number of people's travel requirements,the city's dependence on the subway continues to increase,forcing the construction and extension of subway lines.The subway station uses a large number of various hardware facilities to maintain the stable and safe operation of the subway.This puts forward higher requirements for the management platform in the subway station so that it can form a unified,interrelated,comprehensive data collection and monitoring management system that can coordinate work among the hardware devices,and achieve highly shared data of the equipment in the station.Provides effective tools for daily management of managers.In terms of software design,this thesis first elaborated the development background and significance of the automated data acquisition and monitoring system for subway stations,analyzed the current status of the similar systems at home and abroad,and the main contents of this system research;Secondly,the related knowledge of OPC UA(Object Linking and Embedding for Process Control Unified Architecture)specification technology and COM(Component Object Model)technology is described in this system;Finally,the system requirements and system design and system implementation of this system are performed.In the system design,the OPC UA server is used to access the functional interfaces exposed by the OPC DA server by mapping the main functions to the functions of the OPC DA server.So the architecture of the server is designed to solve the compatibility problem with the old system.And using the Softing SDK development package as the core architecture of the entire system,based on which the system's client and server programs were developed.In terms of software testing,functional and non-functional tests are performed on the system designed and implemented in this thesis.The test results are analyzed.The results show that the system designed by this project is stable,reliable,and has good performance and achieves the purpose of design.At the end of this thesis,summarize the problems and deficiencies in the system and determine the directions for further research and development in the future. |
