【正文】 CU receives the alarming signal that is collected by the sensors, and controls GSM module sending corresponding alarm information to the householder in time. Through the keyboard and display module which can default and change the alarm telephone numbers, users can change alarm telephone numbers. Through the wireless infrared remote controller, user also can control the switch of the system. The system needn?t to form a special alarm work, by means of the existing GSM work to realize the wireless alarm function. The system has good security confidentiality. It is convenient to use, and has a big advantage than traditional alarm system. Key words: GSM mobile work。s wireless security alarm system based on the GSM(Global System for Mobile Communications). With the rapid popularization of GSM works and the fast development of mobile munication technology, GSM technology will be applied to achieve practical application of intelligent alarm home value. This design mainly relies on the most reliable and mature GSM mobile work, by the solution to send a message, directly sent the alarm information to mobile phone. This design mainly uses AT89C52 single chip microputer as the main control chip, controlling normal operation of the whole system。 該系統(tǒng)不需要再組建專用的報警網(wǎng)絡(luò)，利用已有的 GSM 網(wǎng)絡(luò)來實現(xiàn)無線報警功能，具有很好的安全保密性，并且非常方便用戶使用，比傳統(tǒng)的報警系統(tǒng)有著很大的優(yōu)勢。本設(shè)計主要采用 AT89C52 單片機(jī)作為主控制芯片，控制著整個系統(tǒng)的 正常運行，采用 HCSR501 熱釋電紅外傳感器進(jìn)行安保監(jiān)控，采用 MQ2 煙霧傳感器監(jiān)控火情，單片機(jī)接收傳感器采集的報警信號，通過判斷，及時控制 GSM 模塊發(fā)送相應(yīng)的報警信息給戶主。 隨著 GSM 網(wǎng)絡(luò)的迅速普及以及移動通信技術(shù)的快速發(fā)展，利用 GSM 網(wǎng)絡(luò)實現(xiàn)家庭遠(yuǎn)程監(jiān)控是非常具有實際應(yīng)用價值的。尤其是上班族，他們的大部分時間是不在家的，因此他們希望通過自動監(jiān)測報警系統(tǒng)來隨時隨地的掌 控家中的安全情況，以往的防盜系統(tǒng)包括防盜門、防盜窗已遠(yuǎn)遠(yuǎn)不能滿足人們的需要。 唐 山 學(xué) 院 畢 業(yè) 設(shè) 計 設(shè)計題目： 基于 GSM 的家庭防盜報警系統(tǒng)的設(shè)計與實現(xiàn) 系 別： 信息工程系 基于 GSM的家庭防盜報警系統(tǒng)的設(shè)計與實現(xiàn) 摘 要 隨著社會的進(jìn)步以及科學(xué)技術(shù)的快速發(fā)展，人們 的 生活水平 日益 提高， 與此同時， 對 住宅 的 要求 也越來越 高。 家居環(huán)境不僅要舒適化，而且要安全化和智能化 。 本設(shè)計是一種基于 GSM(Global System for Mobile Communications)短信模塊的家庭無線防盜報警系統(tǒng) 。本設(shè)計主要借助最可靠、最成熟的 GSM 移動網(wǎng)絡(luò)，以最直觀的短消息的形式，直接把報警情況反映到手機(jī)上，具有非常好的遠(yuǎn)程監(jiān)控效果。本設(shè)計還具有鍵盤顯示模塊可以預(yù)設(shè)和改變報警電話號碼，方便用戶實時更改報警電話號碼，還可以通過無線紅外遙控控制布、 撤 防。 關(guān)鍵詞 ： GSM 移動網(wǎng)絡(luò) AT89C52 單片機(jī) 傳感器 遙控器 Design and Realization of Family Security Alarm System Based on the GSM Abstract Along with the progress of society and the rapid development of science and technology, people?s living standards are rising. At the same time, people have a higher demand for residence. Household environment is not only fortable, but also more and more secure and intelligent. Especially for the office worker, most of their time is not at home, so they hope through the automatic monitoring alarm system to control the security situation of home at any time. The past security systems including security doors, antitheft window hasn?t far meet the needs of people. This design is a kind of family39。 the HCSR501 pyroelectric infrared sensor is used as security monitoring。 AT89C52 MCU。 Remote controller 目 錄 1 引言 ................................................................................................................................ 1 2 總體設(shè)計方案 ................................................................................................................ 2 3 系統(tǒng)硬件設(shè)計 ................................................................................................................ 3 系統(tǒng)組成模塊 ...................................................................................................... 3 AT89C52 簡介 ....................................................................................................... 3 AT89C52 引腳介紹 ..................................................................................... 3 AT89C52 串口簡介 ..................................................................................... 6 AT89C52 功能 ............................................................................................. 8 GSM 模塊 .............................................................................................................. 8 GSM 簡介 .................................................................................................... 8 TC35 介紹 ................................................................................................... 8 單片機(jī)與 GSM 模塊串口通信 ................................................................ 11 GSM 模塊電路連接原理圖 ...................................................................... 13 AT 指令介紹 .............................................................................................. 13 PDU 編碼規(guī)則 .......................................................................................... 14 鍵盤顯示模塊 .................................................................................................... 14 傳感器模塊 ........................................................................................................ 15 紅外傳感器 .............................................................................................. 15 煙霧傳感器 ............................................................................................... 16 傳感器連接電路 ....................................................................................... 17 遙控器模塊 ........................................................................................................ 18 4 系統(tǒng)軟件設(shè)計 .............................................................................................................. 20 系統(tǒng)開發(fā)環(huán)境 .................................................................................................... 20 Keil C51 簡介 ............................................................................................ 20 Proteus 簡介 .............................................................................................. 22 系統(tǒng)主程序流程圖 ..................................................................
