【正文】 西南科技大學本科生畢業(yè)論文 I 智能門禁系統(tǒng)設計 摘要 : 隨著射頻技術的飛速發(fā)展及其應用范圍 的越發(fā)寬廣,在身份識別和安防等行業(yè),門禁系統(tǒng)作為智能建筑的重要單元越來越得到重視,從原始的機械鎖操作到如今刷卡的智能門禁系統(tǒng)。射頻識別技術的出現(xiàn)彌補了原來門禁系統(tǒng)的不足,而且讓門禁系統(tǒng)變的更加安全、便捷和實用。射頻標簽是 采用 非接觸式, 具有 讀寫速度快、功耗低 等優(yōu)點 。 本文設計了一種采用 RFID( Radio Frequency Identification)技術的高安全性的智能門禁系統(tǒng) 。首先分析了門禁系統(tǒng)的國內(nèi)外發(fā)展現(xiàn)狀和趨勢,闡述了門禁系統(tǒng)當前存在的 問題,引出課題研究目的和意義, 給出 了智能門禁系統(tǒng)設計方案,并對射頻識別技術進行了闡述, 研究 了射頻識別系統(tǒng)的工作原理、主要技術參數(shù)和相關的關鍵技術。其次 完成 了系統(tǒng)硬件和軟件設計, 對硬件電路芯片的選擇、硬件驅動程序的設計、串口通訊程序的設計等作出了具體詳細的 分析 。 最后對 智能門禁系統(tǒng)進行檢測 , 當使用者進入門禁系統(tǒng)的檢測范圍時,系統(tǒng)會自動 獲取身份信息確定該使用者是不是授權用戶,并且記錄進出人員信息,對非授權用戶發(fā)出 報警 信號。 經(jīng)試驗測試,達到設計要求 。 關鍵詞 : RFID;智能門禁; IC卡; STC89C52 Design of intelligent access control system 西南科技大學本科生畢業(yè)論文 II Abstract: With the rapid development of radio frequency (RFID) technology and its application more and more broad, in the identification and security industries, access control system as an important element of intelligent building more and more importance has been attached to the, from the original mechanical lock operation to today39。s credit card intelligent access control system. The emergence of radio frequency identification technology has made up the shortage of the original access control system, and makes access control system bee more secure, convenient and practical.. Radio frequency tags are noncontact, read and write fast and low power consumption. In this paper, a high security intelligent access control system is designed, which is based on RFID (Frequency Identification Radio) technology.. Begins with an analysis of the access control system of the domestic and foreign development status and trends, describes the problems existed in current access control system, leads to the purpose and significance of the topic research, based on the design scheme of the intelligent entrance guard system, and on the radio frequency identification technology is discussed in this paper, introduces the radio frequency identification system, the working principle, main technical parameters and related key technologies. Secondly, the hardware and software design of the system are introduced, the choice of hardware circuit, the design of the hardware driver, the design of serial munication program, etc.. Finally, summary the paper, summarizes the research contents and results of this paper, when the user enters the detection range of access control system, the system will automatically obtain identity information to identify the user is not authorized to the user, and records and personnel information, to non authorized user sends out the alarm signal. The project also needs to improve the place, and the prospect of the development of RFID technology.
