【正文】 本科生畢業(yè)設(shè)計(jì) 智能門(mén)禁系統(tǒng)的設(shè)計(jì)制作 The Design of Intelligent Access System 摘 要 門(mén)禁系統(tǒng)是 一種新型的智能管理模式 ， 對(duì)于現(xiàn)今的安全管理起了不可替代的作用 。 在科技發(fā)展和社會(huì)財(cái)富不斷增長(zhǎng)的今天 ， 為了加強(qiáng) 主要 工作管理區(qū) 、 進(jìn)出 口、 珍貴 物品的 儲(chǔ)存室 、設(shè)備 的 控制 管理中心、電梯口等重要通道 安全防護(hù) 處理辦法 ， 開(kāi)發(fā)相應(yīng)的智能門(mén)禁系統(tǒng)，來(lái)識(shí)別進(jìn)出 人員的身份 資料 ，對(duì) 進(jìn)出通道進(jìn)行安全防護(hù)和控制就有了很大的必要性 。 通過(guò)對(duì)當(dāng)代門(mén)禁系統(tǒng)發(fā)展概況和技術(shù)的研究，本方案提出以單片機(jī)為中央控制系統(tǒng)，加 LCD 液晶顯示電路、鍵盤(pán)輸入電路、讀卡電路等外圍電路，來(lái)完成非接觸式 IC卡和密碼兩種方法控制的門(mén)禁系統(tǒng)。在 具體 的 使用中， 當(dāng)感應(yīng)卡 接近讀卡機(jī) 或有密碼通過(guò)鍵盤(pán)輸入時(shí) ，合法 的 卡信號(hào) 正確的密碼，繼電器工作， 電鎖 便會(huì) 自動(dòng)打開(kāi)，非法卡 和錯(cuò)誤的密碼將被禁止訪問(wèn)，并在顯示器上提示卡是否合法，密碼是否正確。系統(tǒng)設(shè)計(jì)簡(jiǎn)單，性能可佳，實(shí)用性較強(qiáng)。 關(guān)鍵詞 ： 智能門(mén)禁系統(tǒng)；非接觸式 IC卡；鍵盤(pán)密碼 ABSTRACT Access Control System is a new type of intelligent management,security management for today played an irreplaceable role. In technological development and socialy wealth growing today,in order to strengthen the management of the main work area an important channel to control the import and export management center, storage room precious items, equipment, elevator and other security approach, the development of appropriate smart access control systems, to identify the identity and out of personnel to carry out security and control channels have a great necessity. By studying the development of contemporary overview of access control systems and technologies, the program made a microcontroller as the central control system, plus LCD display circuit, keyboard input circuit, circuit card reader and other peripheral circuits to plete noncontact IC card and two passwords methods to control access control system. In the specific use, when close proximity card reader or have the password via keyboard input, legitimate card signals the correct password, relay, power locks will open automatically, illegal card and the wrong password will be denied access, and tips on the display card is legitimate, the password is design is simple,the performance can be good,practical, strong. Keywords: intelligent access control systems noncontact IC card keyboard password 目 錄 1 緒論 ................................................................................................................................... 1 門(mén)禁系統(tǒng)簡(jiǎn)介 ........................................................................................................ 1 門(mén)禁系統(tǒng)的發(fā)展趨勢(shì) ............................................................................................ 1 2 門(mén)控系統(tǒng)設(shè)計(jì)方案 ........................................................................................................... 2 門(mén)禁系統(tǒng)的方案選擇 ............................................................................................ 2 門(mén)禁系統(tǒng)的組成 .................................................................................................... 3 系統(tǒng)實(shí)現(xiàn)功能 ........................................................................................................ 3 最小系統(tǒng)的設(shè)計(jì) .................................................................................................... 3 3 門(mén)禁系統(tǒng)的硬件設(shè)計(jì) ....................................................................................................... 5 門(mén)禁控制器 ............................................................................................................ 5 射頻卡與讀寫(xiě)器 .................................................................................................... 9 射頻卡 ......................................................................................................... 9 讀寫(xiě)器 ....................................................................................................... 10 電控鎖 .................................................................................................................. 11 繼電器 ....................................................................................................... 11 電控鎖分類(lèi) ............................................................................................... 11 鍵盤(pán)設(shè)計(jì) .............................................................................................................. 12 LCD12864 液晶顯示 ............................................................................................. 12 4 門(mén)禁系統(tǒng)的軟件設(shè)計(jì) ..................................................................................................... 15 軟件開(kāi)發(fā)環(huán)境 ...................................................................................................... 15 軟件整體流程圖 .................................................................................................. 15 鍵盤(pán)程序流程 ...................................................................................................... 16 讀卡程序流程 ...................................................................................................... 16 5 門(mén)禁的系統(tǒng)軟硬件調(diào)試操作 ......................................................................................... 19 硬件調(diào)試 .............................................................................................................. 19 軟件調(diào)試 .............................................................................................................. 19 實(shí)際效果 .............................................................................................................. 19 結(jié) 論 ............................................................................................................................. 21 參考文獻(xiàn) ............................................................................................................................. 22 附錄 程序 ................................................................................................................
