This phenomenon presented a new challenge for the municipal transportation. Take the parking problem as all example, the city39。s parking spaces is far from enough nowadays. The traditional parking management technology Call not satisfy the needs. At present, the parking lot is turning toward larger scale, higher effective and more intelligent. The intelligence management system for parking lot based on RFID technology can be called the most economical, practical, convenient and efficient management system for parking lot. This paper concentrates efforts on researching and designing an intelligent manage system for the smart parking lot, which is based on the technology of RFID, which Can bring the automatic management and ensure every vehicle safety. It presents a framework of this system and has researched on the related techniques. Firstly, this paper introduced the background of intelligence management system, in this Paper the basic principles, structure, characteristics, munication coding, and the relevant theoretical knowledge of the radio frequency identification technology were introduced. Especially, this paper has done an in—depth research on the data transmission in the issue of anti—collision and authentication protoc01. Secondly, the total scheme of this system Was given. The design requirements and principles of the system, overall framework and workflow of the system, hardware configuration of the system were included. Thirdly, this system based 011 RFID technology applies technologies of puter work, puter control and database. The system included the application to decide system’s major function, which process the management of basic information of vehicles,the management of application dispatch of vehicles and the maintenance and passing in and 更多相關參考論文設計文檔資源請訪問 本參考設計材料,包含項目源代碼,屏幕錄像指導、項目運行截圖、項目設計說明書、任務書、報告書以及文獻參考翻譯等,完整的設計文件及源代碼,資料請聯系 68661508 索要 out of vehicles. The kit of development is c, database selects SQL Server 2020 and operating system selects Windows Server2K/Windows XP. Fourthly, this paper introduced some time division multiple algorithms(TDMA) which has being generally accepted, such as ALOHA protocol, and Binary tree protocol, analyzed characteristics and shortings . After that a new autoadapted dynamic grouping anticollision algorithm Was proposed which using HASH function to determine the grouping, it has confidentiality, and system throughput advantages. The article also carried out the algorithm of mathematical analysis, the throughput of the system MATLAB’S simulation and the experimental results and conclusion are given. Finally, conclude the main work of this Paper, and then make a prospect and plan for the further studies. Key words: radio frequency identification(RFID); vehicles access control; shortest parking path search; anticollision algorithm; 更多相關參考論文設計文檔資源請訪問 本參考設計材料,包含項目源代碼,屏幕錄像指導、項目運行截圖、項目設計說明書、任務書、報告書以及文獻參考翻譯等,完整的設計文件 及源代碼,資料請聯系 68661508 索要 目錄 摘 要 ................................................................... i Abstract ................................................................ ii 1 緒論 .................................................................. 1 選題背景和意義 .................................................... 1 停車場管理系統的現狀與發(fā)展趨勢 .................................... 1 國內停車場管理系統的現狀和趨勢 ................................. 2 國外停車場管理系統的現狀和趨勢 ................................. 3 論文的主要工作 .................................................... 3 2 RFID 系統及組成原理 ................................................... 4 RFID 系統的基本組成 ............................................... 4 電子標簽 ....................................................... 4 讀寫器 ......................................................... 5 中間件 ......................................................... 7 應用系統軟件 ................................................... 7 RFID 系統的射頻工作原理 .......................................... 7 電感耦合 RFID 系統 ............................................. 8 電磁反向散射 RFID 系統 ......................................... 8 無線射頻識別的標準 ................................................ 9 技術標準 ....................................................... 9 應用標準 ...................................................... 10 數據內容標準 .................................................. 10 性能標準 ...................................................... 10 小結 ............................................................. 11 3 智能停車場管理系統硬件設計 ........................................... 12 智能停車場管理系統 ............................................... 12 停車場系統的性能特點 .......................................... 12 智能停車場的優(yōu)點 .............................................. 12 RFID 讀卡模塊 .....................
