Desing And Implementation Of MVC Pattern-based WEB Management System For RFID Readers

RFID(Radio Frequency Identification)as a new non-contact automatic identification technology has been widely used in warehouse management,radio frequency access control,electronic traceability,product security and many other industries,because it has a high management efficiency,low operating costs and good environmental adaptability,etc.However,with the RFID system more widely used,the number of readers which needed deploying is also increasing rapidly,which has presented new challenges to RFID reader management system.To solve the current problems of reader management in planning deployment,data collection and parameter configuration,this paper dedicated to the design and implement the management system of the large-scale RFID readers.Mainly including the RFID reader management system architecture design,interface module implementation and the PC software implementation.First,summarize the core architecture of the system.Put forward a new reader network deployment scheme according to the demand analysis.The scheme has a simple structure and good performance of extension,it can also save the hardware resources effectively.After that,propose the core architecture of the system,the system consists of PC software and three interface modules,and elaborate the function modules combined with case diagram.The architecture adopts modular design concept,which effectively improves the system's maintainability.Secondly,design and implement three interface modules,which are responsible for connecting the PC software with the readers,the database and the application systems.Among them,the reader access interface module includes the description of the reader hardware,the design of access interface and invoking method.The database access interface module includes the design of database tables and the realization of the data access interface,this interface uses Spring data framework to simplify the database access.The application system access interface module including the design of the web services interface,this interface meet the REST specification,which effectively reduce the complexity of web service development.Finally,design and implement the PC software,which is responsible for implementing the business functions.Firstly the PC software control the underlying hardware through reader access interface,and get the electronic tag data collected by the readers,then store it to the database through the database access interface,finally publish the results through the application system access interface.The PC software is based on based on Maven construction.Use Spring frameworks to implement the tlhree-tier architecture,which reflects the "high cohesion,low coupling" ideas.Use Ajax and Java multithread technology to enhance the system's response and throughput rate.I successfully deployed and managed several RFID readers by using the system mentioned by this dissertation.
