基于單片機(jī)的智能門禁系統(tǒng)

摘 要：           

為了科學(xué)地管理特定區(qū)域的出入權(quán)限，在管理區(qū)域中建立一套現(xiàn)代化的智能門禁監(jiān)控管理系統(tǒng)是必不可少的。

本文首先簡單介紹了非接觸式IC卡的技術(shù)，通過與接觸式IC卡的比較，說明了非接觸式IC卡的特點(diǎn)和優(yōu)勢。本課題研究開發(fā)了基于非接觸式IC卡識別的門禁系統(tǒng)。詳細(xì)分析了系統(tǒng)的硬件設(shè)計(jì)和軟件設(shè)計(jì)，以及主要程序設(shè)計(jì)的流程圖和程序。形成了一套完整的門禁監(jiān)控管理系統(tǒng)。

該系統(tǒng)以單片機(jī)W77E58為核心門禁控制器；以鍵盤和zlg500B讀卡模塊作為門禁系統(tǒng)的核心部分，并與PC機(jī)組成通信網(wǎng)絡(luò)系統(tǒng)，來達(dá)到以卡識別身份和驗(yàn)證信息的目的。同時還擴(kuò)展有狀態(tài)指示燈和蜂鳴器用于讀卡狀態(tài)指示。此外，該部分還包含有LCD接口電路，歷時芯片DS1302，AT24C256存儲器設(shè)計(jì)以及開關(guān)等模塊。實(shí)驗(yàn)證明系統(tǒng)的可行性。

The Intelligent Guard Control System based on MCU

Abstract: In order to manage in and out rights of location area effectively, it is absolutely necessary to set up a set of modern intelligent access control system.

Firstly, this paper briefly introduces the RFIC card technology and the feature and the advantage of IC card through comparing with the no-contact IC card. This paper main makes a study of guard system with IC card, and analysis the design of hardware and software detailed, gives  the main flow chart and program, it forms a completely guard control system.

The design uses W77E58 as the core entrance guarder. The keyboard and card-reader module zlg500B are the core-part of this entrance guard system. They communicate with PC computer to identify the correctly of the user. Besides, it has the state designation lights and buzzer using for the state designation of reading card. In addition, this part also includes the design of interface circuit of LCD, chip of time and date DS1302, AT24C256 memory, and digital signals and pulse signals. The experiment proves that the system is feasible.
