Design And Implementation Of Information Publishing Subsystem Of Metro Monitoring Experimental Platform

The pressure of transportation increased, because the urban population increased with the development of society and urbanization.Metro is an important means to improve the transport capacity. The normal operation of metro equipment is the basis for the safe and efficient operation of metro. It can improve the safety level of metro operation by monitoring the metro equipment and finding out the fault as soon as possible. The analysis of faults of metro equipment can guide the maintenance and repairing work of metro.In view of the above background, SpringMVC, Spring framework,Mybatis and Java are used to design and implement the information publishing subsystem of metro monitoring experimental platform.Firstly, the background, the goals and the tasks of the project are briefly introduced. Secondly, the related technologies are introduced including spring framework, privilege management based on RBAC,MQTT protocol, EMQ message broker and Java object serialization technologies. Thirdly, the functional requirements and nonfunctional requirements are analyzed. Functional requirements include management of user and privilege, real-time monitoring, query on fault records and statistics on fault records. Then, the outline design is introduced including design of system architecture, design of interfaces among modules,database design, system deployment architecture design and front page architecture design. The detailed design and implementation of each function module are introduced with class diagrams, flow diagrams,sequence diagrams and text descriptions. Furthermore, the deployment environment and test cases are introduced, and the testing result is analyzed.Finally, the work results are summarized, and the future work is prospected.
