Especially nearer year our country mechanical and electrical trend rapid is risen and becomes the pillar industry of country, among them the intelligentization product also will become the development trend of our country mechanical and electrical trade. The systems of automatic door controller is the typical product of intelligentization. Owing to the fact that is above the technology of IC cards that to base on at present ripe, and that to expend also very convenient is nimble the merit, and confidentiality capability is good, so getting the extensive application. The system of automatic door controller is the one of kind of mechanical and electrical integration product of model. It has the aid of the intelligent card technology by way of the Single-Chip Microcomputer, as well as the management of data base, and now excluding various interfaces of boundary, display and keyboard to realize the big and powerful merit ability. It also develops becomes a perfect technology in our country. So we have developed a new kind of automatic door controller based on SPEC061A.The controller has good competitive ability because it is powerful, reliable, convenient and low-cost. AT89C51 is is powerful cheap. It has been widely used in many industry controller fields because of its excellent anti-interference feature. It is very suitable to AT89C51 as the core unit of automatic door controller and so we did choose it. Key words：automatic door controller; integrated circuit card; AT89C51  目 录 第1章　概述 1 1.1　课题背景 1 1.2　智能门控系统的意义 2 1.3　智能门控系统的发展趋势 2 1.4　本文主要内容 3 第2章　系统的方案设计与选择 4 2.1　方案的选择 4 2.2　IC卡的选择 4 2.3　复位与应答 8 2.4　同步通讯与异步通讯 9 2.5　串行通讯的传输方向 10 2.6　设计原理 10 2.7　设计功能 11 2.8　本章小结 11 第3章　系统的硬件设计 12 3.1　电路基本原理 12
