【正文】 基于無線網絡的防盜報警系統(tǒng) 中文摘要 隨著國家智能化小區(qū)建設的推廣，防盜系統(tǒng)已成為智能小區(qū)的必需設備 。本 系統(tǒng) 利用單片機控制技術和無線 通信 技術， 以及相關的傳感器技術， 開發(fā) 了 一種具有聯網功能的智能無線防盜系統(tǒng)。 本系統(tǒng) 采用無線數據傳輸方式，不需重新布線，特別適用于已裝修用戶及布線不方便的場合。 本 設計 利用無線數據收 /發(fā)芯片 nRF2401 和微控制器件 AT89S52 構成 了 無線數據傳輸系統(tǒng) 。本論文詳細敘述 了系統(tǒng)的硬件電路設計和軟件 程序 設計 ,以及無線數字傳輸芯片在突發(fā)傳遞模式下 ， 通過單片機的控制進行無線數據傳輸的原理。該無線報警系統(tǒng)可以對整個家居的安全環(huán)境進行實時監(jiān)控。監(jiān)控的范圍為室內入侵盜竊的不安全因素。一旦有上述安全事故的發(fā)生，該報警系統(tǒng)就會發(fā)出相應的報警及用戶的相關信息，可以使小區(qū)管理中心在得到報警信息后，立即采取有效的應急措施，對事故進行緊急處理。運行表 明 ,該系統(tǒng)控制方便 ,工作穩(wěn)定 ,功耗低，能實現可靠的無線數據傳輸。 關鍵詞：無線數據傳輸； AT89S52； nRF2401。 LCD12864 Antitheft Alarm System Based on Wireless Network ABSTRACT Antitheft alarm system has bee essential equipment in the intelligent munity with the promotion of national intelligence munity building. The system used the technology of microcontroller and wireless munication to develop an intelligent antitheft system with capability of joining the inter and also used some sensors Related. This system adopted the way of wireless Transmission, no rewiring, especially suited for the house renovated and the place where convenient wiring. This technology used the wireless data transmit / receive chip nRF2401 and microcontroller AT89S52 to design a Wireless Data Transmission System, described the designing of hardware and software of the system clearly, and explained the principle of transmission of wireless digital chip in the burst transmission mode. The wireless alarm system can monitor the safety of the whole house. The range of monitoring are the insecurity factors that Indoor invasion theft. Once these insecurity factors, the alarm system will send the appropriate alarm and user messages to Community Management Center. Immediately, the management can take effective emergency actions to deal with the emergency incidents. Realty showed that the control of this system is easy, the faction is stable. It has low power consumption and be able to achieve reliable wireless data transmission. Keywords: Wireless Data Transmission 。 AT89S52 。 NRF2401。 LCD1286 1 目錄 第一章 前言 .......................................................................................................................................... 1 ................................................................................................................................... 1 ............................................................................................................................ 2 第二章 總體設計方案論證與比較 ........................................................................................................... 3 ................................................................................................................................... 3 ................................................................................................................. 4 ..................................................................................................................... 4 傳感器選擇 .................................................................................................................... 4 /接收模塊 ........................................................................................................ 6 ........................................................................................................................ 7 第三章 系統(tǒng)硬件電路設計與實現 ........................................................................................................... 8 nRF2401 及其外圍電路 ............................................................................................................. 8 熱釋電傳感器及其外圍電路 ...................................................................................................... 9 紅外對管防入侵電路 ................................................................................................................ 9 第四章 系統(tǒng)軟件的設計與實現 ............................................................................................................ 11 ................................................................................................. 11 .........................................................................................
