【正文】 安防系統(tǒng) ,它作為一種新型現(xiàn)代化安全管理系統(tǒng)，集自動(dòng)識(shí)別技術(shù)和現(xiàn)代安全管理措施為一體。本文以開發(fā)基于射頻識(shí)別技術(shù)的門禁系統(tǒng)為目標(biāo)，研究了門禁系統(tǒng)中的關(guān)鍵技術(shù)及其應(yīng)用，包括了門禁系統(tǒng)軟硬件設(shè)計(jì)、天線設(shè)計(jì)、數(shù)據(jù)安全性分析、系統(tǒng)抗干擾性設(shè)計(jì)等。 主要的研究?jī)?nèi)容和工作： 1） 以 MF RC500 為核心，結(jié)合單片機(jī)、液晶屏等設(shè)計(jì)了一套門禁系統(tǒng)，其中包括了讀寫器、液晶 屏、鍵盤接口等軟硬件的設(shè)計(jì)，并在現(xiàn)場(chǎng)對(duì)該門禁系統(tǒng)進(jìn)行調(diào)試和優(yōu)化。 關(guān)鍵字：門禁系統(tǒng) 。MF RC500 基于 RFID 門禁控制系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn) II Based on RFID Access Control System Design and Implementation Abstract Access control management system,which is also known as access door control system,belongs to the intelligent elf system of a security system,as a kind of new modern safety management system,set to be automatic identification technology and modern safety management measures for an anic whole. It can automatically record personnel and out of time,limit the people inside and out of area, in and out of time,politely refuse to freeloaders,also will effectively protect your property shall not be infringed paper based on the development of rid technology entrance guard system as the goal,the entrance guard system of the key technology and its application,including entrance guard system hardware and software design,antenna design,data security analysis,system antijamming design, development of the entrance guard system has been put into use and obtain good effect. The main research contents and work: 1)the MF RC500 as the core,bining SCM,LCD,such as design a set of entrance guard system,including the writing and reading device,liquid crystal screen,keyboard interface of software and hardware design, and to the entrance guard system in the debug and optimize. 2)the system of MF RC500 chip of the procedure,And use the corresponding development of reading and writing the language is the bottom control software,and put on the card of the different operating plait procedure module,convenient system upgrade. Key Words： Entrance Guard System。 MF RC500 基于 RFID 門禁控制系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn) III 目 錄 摘 要 .......................................................................................................................................
