【正文】 , to develop a convenient and easy operation of the information written code measures, in order to the pleted the effective method of a simple infrared data munication system. The design and principle of the related modules of the circuits are pared and pared.. The maximum degree of error rate is reduced, so that the information can be improved in the transmission process.. The design of this system mainly based on the control of single chip write, scan and input the ranks of the keyboard value, the related digital tube dynamic display, infrared data munication clear show. This paper mainly from the position and the working principle of the infrared data munication and its coding and decoding of work on, the theme is divided into two modules to discuss, both for the reception and sending of two parts, and finally according to the related information and standard to plete the final design of the hardware part of the. Keywords： MCU； LED display； Infrared municationXXXXXXXX I XXXXXXXX 目錄 摘要 ................................................................................................................................................. i Abstract ..........................................................................................................................................ii 第 1 章 緒論 ............................................................................................................................... 1 背景 ............................................................................................................................... 1 研究的基本內容與擬解決的主要問題 .................................................................. 2 本章小結 ...................................................................................................................... 2 第 2 章 終端節(jié)點電路的方案設計 ........................................................................................ 3 無線數(shù)據(jù)傳輸模塊 .................................................................................................... 3 課題設計的目的及目標 ............................................................................................ 3 設計目標 .............................................................................................................. 4 課題設計 .............................................................................................................. 4 設計思路 .............................................................................................................. 4 開發(fā) 工具 ...................................................................................................................... 6 protel99se ............................................................................................................. 6 keil 分析 ............................................................................................................... 6 主要芯片介紹 ............................................................................................................. 7 Philips89lpc935 ................................................................................................... 7 主要特性 .............................................................................................................. 7 附加特性 .............................................................................................................. 7 本章小結 ...................................................................................................................... 8 第 3 章 系統(tǒng)硬件電路設計 ....................................................................................................... 9 MCU 外圍電路 ........................................................................................................... 9 紅外發(fā)射接受部分 .................................................................................................. 10 鍵盤模塊和顯示模塊 .............................................................................................. 11 電源模塊 .................................................................................................................... 12 URT 串口通信模塊 .................................................................................................. 13 詳述主機與從機的通信過程 ................................................................................. 14 注意事項 .................................................................................................................... 14 本章小結 .................................................................................................................... 14 第 4 章 系統(tǒng)軟件設計 .............................................................................................................. 15 系統(tǒng)總流程 ............................................................................................................... 15 紅外數(shù)據(jù)通信的編碼格式 ..................................................................................... 15 XXXXXXXX II XXXXXXXX 主機程序 .................................................................................................................... 16 從機程序 .................................................................................................................... 21 系統(tǒng)調試與測試 ....................................................................................................... 28 本章小結 .................................................................................................................... 29 致謝 .............................................................................................................. 錯誤 !未定義書簽。 本文主要從紅外數(shù)據(jù)通訊的組成原理及其關的解碼與編碼工作所進行研究，文章主題被分為兩大模塊來進行討論，既為接受及發(fā)送兩部分，并最終參照其相關的信息及標準完成其硬件部分的最后設計。最大程度上降低其所產(chǎn)生的誤碼率，從而使相關的信息在傳送過程中能夠提高其速率。本設計主要以 89lpc935單片機為其設計依據(jù)，制定出了一個方便易操作的 信息寫碼對策，以此作為其完成了一個簡潔的紅外數(shù)據(jù)通信系統(tǒng)的有效方法。因其所具有的較低成本、較好的擴展功能、自由的工作條件以及方便接入的優(yōu)勢等，在相關的虛擬產(chǎn)品市場、安全警報系統(tǒng)、傳感器無線網(wǎng)絡系統(tǒng)等多方面領域都具有十分廣闊的前景。 XXXXXXX i XXX
