| According to the bus information collected by the equipment,together with the actual demand of the company,the thesis studies and designs the bus information management system so as to present the information of electronic components in vehicles using data visualization tools to make the vehicle operators and managers carry out monitoring and performance management easily.The system is a three-layer structural model which is based on B/S framework and developed by Java language.The three layers are separately,data access layer,business logic layer and presentation layer.The database applies relational database Oracle and data persistence layer uses Hibernate frame to achieve data persistence,and then utilizes Mybatis frame to inquire the report data.Business logic layer,which is between data access layer and presentation layer,mainly uses SpringMVC frame.It is a connecting link in data exchange and is mainly used for processing data.Interface layer applies the technology of JSP and JQuery,together with Ztree,Jqgrid,Highchart and other plug-in to achieve a much wonderful visualization effect and improve the user experience through Ajax technology.Through the hierarchical architecture design,the coupling among each functional layer is weakened,which is beneficial..for the later maintenance of code.The bus information management system designed in this thesis has come into use in some bus companies.The bus administrators can learn about the vehicle information visually and dynamically through the system and then carry out efficient check on those problem vehicles,which greatly simplifies the troubleshooting procedures.Besides,they can also monitor the driving behavior of drivers through vehicle information to supervise and advise the drivers who have unsafe driving act to change their harmful driving habits.Therefore,the bus information management system is of great significance to improve the management quality and work efficiency of bus companies. |
