Control System in the field of intelligent architecture. Refers to the forbidden permissions door, is the guard of door. Access control system is to protect the facilities indispensable in life, a safety management system is the most close to the development of the science and technology society, the intelligent entrance guard system relates to the electronic, mechanical, optical, puter technology, munication technology, biological technology and other new technology. It is pletely solve some important departments and residential one of the most effective security management measures to achieve the entrance. Applicable to all kinds of important departments such as banks, hotels, rooms, intelligent residential, office and factory. It plays an ideal role in personnel attendance management, safe working environment and other administrative work. Based on access control system on the corresponding increase in the auxiliary equipment can monitor system, elevator control, vehicle access and population differences and so on, the real implementation of the region a smart card management. Access control systems have already gone beyond the simple road and key management, it has developed into a very plete access control system This design content is wireless access control system based on IC card. In bination with the now demand status of people, prehensive parison of access control system based on the monly used, carried out the other application of IC card promotion. This graduation design includes the hardware design, software design, hardware and software debugging and will be integrated into a system Keywords: Access control system Intelligent building Monitoring system The elevator control 智能門禁控制系統(tǒng)設(shè)計 3 前言 門禁系統(tǒng),又稱為出入口控制系統(tǒng),在科學技術(shù)發(fā)達的今天,已發(fā)展為一套現(xiàn)代化的、功能齊全的管理系統(tǒng)。 智能門禁控制系統(tǒng)設(shè)計 4 1 智能 門禁系統(tǒng)簡介 概述 在越來越注重商業(yè)情報和安全的今天,對進出一些重要機關(guān)倉庫、科研實驗室、檔案館、以及關(guān)系到國計民生的公用事業(yè)單位的控制中心、民航機場等場所的工作人員,給予進出授 權(quán)控制是非常有必要的。從智能門禁控制系統(tǒng)設(shè)計 5 門禁系統(tǒng)迅猛的成長迅度可以看出該產(chǎn)品的市埸已逐漸成熟,一改往日報警和監(jiān)控產(chǎn)品一統(tǒng)天下的局面,由專家最近執(zhí)行的預測表明:感應(yīng)式門禁系統(tǒng)的市埸正以每年300%的驚人速度增長。每一瑣內(nèi)可存儲多個電子鑰匙的資料,并可由用戶自行添加刪除,增減電力鑰匙的數(shù)量,丟失鑰匙亦無需換鎖。子門鎖是近幾年隨著電子計算機技術(shù),尤其是智能 IC 卡應(yīng)用技術(shù) 的提高發(fā)展起來的,隨之而產(chǎn)生的接觸式智能 IC 卡和密碼 鍵盤門禁系統(tǒng)也越來越被人們重視和使用。 電鎖與執(zhí)行: 電鎖 與執(zhí)行單元部分包括各種電子鎖具、擋車 器等控制設(shè)備,這些設(shè)備應(yīng)具有動作靈敏、執(zhí)行可靠、良好的防潮、防腐性能,并具有足夠的機械強度和防破壞的能力。 感應(yīng)式訊號發(fā)送器 也可有多種選擇,其中包括 卡片式、鑰匙圈式、筆心式、玻璃管式、麥克筆等,體積有大小差別,而體積的大小往往與感應(yīng)距離成正比,為了使用者更加 便于使用和攜帶 ,通常 會 做成卡片式,故俗稱感應(yīng)卡?,F(xiàn)在國際最流行最通用 的還是非接觸 IC 卡門 禁系統(tǒng)。系統(tǒng)的運轉(zhuǎn)真正做到開電即可工作 , 插上就能運行的程度。 基本功能 成熟的門禁系統(tǒng)實現(xiàn)的基本功能: 對通道進出權(quán)限的管理 消防報警監(jiān)控聯(lián)動功能:在出現(xiàn)火警時門禁系統(tǒng)可以自動打開所有電子鎖讓里面的人隨時逃生。 優(yōu)點:從識別角度來說安全性極好;無須攜帶卡片 缺點:成本很高。 2. 485 聯(lián)網(wǎng)門禁,就是可以和電腦進行通訊的門禁類型,直接使用軟件進行管理,包括卡和事件控制。(需聯(lián)網(wǎng)) 可靈活設(shè)定持卡人的開門權(quán)限、開門時間、有權(quán)開門的區(qū)域時段 支持多種開門方式:密碼、刷卡、遠程開門(需聯(lián)網(wǎng)) 可支持多條件靈活組合查詢通行記錄、按不同順序?qū)蟊頂?shù)據(jù)排序、支持報表數(shù)據(jù)打印及導出到文件功能 可與多奧電梯 /停車場 /通道 /消費 /等智能一卡通 ? 單門門禁特點 1) 在標準狀態(tài)下,感應(yīng)距離達到 4070mm; RS485 通訊接口 ; 產(chǎn)品型號:DAICMJ1MB 2) 可實時向門禁管理電腦上傳每次刷卡進出人員的信息。 3. 先進性 系統(tǒng)的設(shè)計和產(chǎn)品選用在投入使用時應(yīng)具有一定的技術(shù)先進性,但不盲目追求尚智能門禁控制系統(tǒng)設(shè)計 17 不成熟的新技術(shù)或不實用的新功能,以充分保護用戶的投資。s Zhangye city during their journey to Kazakhstan, May 5, 2021. The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2021. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2021. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。 he wondered how in the world he came to belong there. Indeed his penning and publishing this essay caused his exmunication from high society and also caused him
