As a background, Developing a control system of low cost automatic opening door based on single chip microputer, introduced the infrared sensor to detect the pedestrian, In this paper, we design control system of the automatic door based on single chip microputer. The system with 51 singlechip puter as the main body, dc motor, the entrance guard system as the core, achieve automatic control of automatic door, achieve to enter the automatic door of office in the outside by password, Within the infrared induction open the door automatically, Equipped with automatic door normally open, normally closed. Through single chip microputer program ,control current servo motor39。s forward and control the door of open and close current motor driven uses H bridge, give full play to the performance of the micro controller. Its advantage is simple circuit, software function is perfect, and reliable control system, high cost performance, has certain use and reference value. Keywords: AT89C51。heat release infrared sensors,。BIS0001 chip。stepping motor。L298N chip。 Password lock 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì) (論文 )報(bào)告用紙 目 錄 引言 ............................................................................................................................................1 1 緒論 .....................................................................................................................................2 自動(dòng)門(mén)的發(fā)展歷史 ................................................................................................2 自動(dòng)門(mén)的功能概述 ................................................................................................2 開(kāi)門(mén)信號(hào) .........................................................................................................2 門(mén)禁系統(tǒng)與非公共區(qū)域的自動(dòng)門(mén) ......................................................................3 對(duì)自動(dòng)門(mén)的要求就是解鎖動(dòng)作與開(kāi)門(mén)動(dòng)作之間的協(xié)調(diào) .......................................3 本章小結(jié) ................................................................................................................3 2 系統(tǒng)硬件設(shè)計(jì) ..................................................................................................................4 自動(dòng)門(mén)設(shè)計(jì)基本思路和原理 ................................................................................4 單片機(jī)和外圍電路介紹 ........................................................................................5 AT89C51 主要性能概述 ...................................................................................5 單片機(jī)時(shí)鐘電路介紹 ........................................................................................8 單片機(jī)復(fù)位電路、電源電路介紹 ......................................................................8 LED顯示和鍵盤(pán) ....................................................................................................9 四位數(shù)碼管 LED 介紹 ......................................................................................9 4*4 矩陣鍵盤(pán) .................................................................................................11 紅外感應(yīng)裝置 ......................................................................................................12 熱釋電紅外傳感器介紹 ..................................................................................12 BISS0001 芯片及 其典型電路 ..........................................................................14 驅(qū)動(dòng)電路 ..............................................................................................................17 L298N 芯片介紹及應(yīng)用 ..................................................................................17 直流電機(jī)分類(lèi)和特點(diǎn) ......................................................................................19 門(mén)行程檢測(cè) ....................................................................................................20 本章小結(jié) ..............................................................................................................20 3 系統(tǒng)軟件設(shè)計(jì) ................................................................................................................21 主程序流程 ..........................................................................................................21 LED顯示模 塊 .....................................................................................................22 鍵盤(pán)掃描模塊 ......................................................................................................23 門(mén)禁系統(tǒng)模塊 ......................................................................................................24 紅外和驅(qū)動(dòng)模塊 ..................................................................................................25 本章小結(jié) ..............................................................................................................26 4 軟件仿真與分析 ...............................................................................
