Research And Design Of Key Technologies For Intelligent Parking Vehicle RFID Location

With the improvement of people’s living standard, the number of cars has increaseddramatically, which brings convenience to people, but also causes the parking problem. This thesismakes research on the application status of parking lot management system that has some defects,and so proposes the research topic which studies on the key technology of intelligent parkingvehicle RFID location. The vehicle information collection for the intelligent parking system shouldbe comprehensive, especially the location information of vehicles, which provides support for theparking guidance service system. The intelligent parking uses RFID to enhance the compatibility ofthe collection information, and constructs lightweight RFID middleware system, which providesconvenient interface for the application layer software development.The major contents in this thesis include: RFID indoor location algorithm which is applied tothe parking lot application scenario and RFID-based real-time location middleware system. Thisthesis analyzes the basic theory of RFID indoor location algorithms, and then proposes a newindoor location algorithm D-LANDMARC based on the traditional LANDMARC algorithm.Compared with LANDMARC algorithm, the simulation result shows that the D-LANDMARCmethod enhances the precision of indoor localization. Furthermore, the thesis analyzes the structureof middleware and the relationship of core modules in detail, defines the structure of the RFIDreal-time location lightweight middleware based on event processing mode. The middlewaresimplifies the application layer interface and has the characteristics of practicability and easyoperation. Finally, this thesis describes the hardware network architecture in the parking and teststhe working process of middleware, and then through the graphical parking management platformsoftware to show the desired results.
