Community Information Management System Based On RFID

With the development of the era and with our country’s urbanization advancement speeding up unceasingly, the number of newly built residential areas have greatly increased. In order to enforce the management of these newly built residential areas and to improve the overall management level of personnel and vehicle within the community, this paper describes the design of a district management system based on radio frequency identification. Radio Frequency Identification (RFID) is a new automatic identification technology developed in nineteen eighties. Compared with the traditional identification technology, RFID has the advantages of high speed, high precision and strong anti-interference ability. It is now widely used in people’s lives, becoming an indispensable technology. Therefore, it has the profound theoretical and practical significance in the study, development and application of RFID technology.Community management system designed in this paper is composed by two parts, one part is to realize the function of the RF card reader in the hypogynous machine, the other part is to finish the system of querying and displaying residents’information in epigynous machine. District residents hold the unique identification tag. RF reader can not only read the tag’s series number, but also send the series number to the community management system in the epigynous machine through the serial port. After querying the database, manager can view details on the resident in epigynous machine. What’s more, these information may also include a motor vehicle, electric vehicle and the store room surround the community. It is very convenient for community manager to supervise and monitor the personnel and vehicles.This paper firstly explains the related theories and protocol of radio frequency identification technology, and then introduces the related technology of software development based on JAVA program, lastly,on the basis of above theories, it puts forward the overall design scheme of community management system. The text introduces the design of RF reader and resident information querying and displaying system in detail. RF reader using STM32as the main control chip and MF RC522as the RF chip. It can achieve the function of communicating with the13.56MHz MIFARE1card. The main work is to design the reader circuit and a PCB antenna,at the same time,write the program for driving the RF reader using C language. The querying and displaying system mainly use JAVA language to complete, the display part is designed to generate a KML file which can run in Google Earth software, in this way, personnel information in each building of this community can be seen directly in Google Earth. The query part is based on the B/S architecture software, we can query the information of personnel and vehicle by IE browser.
