【正文】 XXXXXXX i XXXXXXXXXXXXX 摘要 怎樣解決種類繁多的有線電纜所導致的麻煩及問題，創(chuàng)建一個安穩(wěn)、便捷、安全的環(huán)境狀態(tài)是人們的愿望所在。所以，無線數(shù)據(jù)傳輸方式的誕生改變了其傳統(tǒng)的技術手段。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。 為使其相關的數(shù)據(jù)在進行傳送的過程中能夠具有安全可靠的傳輸性、易于操作、方便其進行運行工作等，可以采用紅外信息技術手段。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。辯證的比較其各電路相關模塊的設計及原理。最大程度上降低其所產生的誤碼率，從而使相關的信息在傳送過程中能夠提高其速率。本系統(tǒng)的設計主要基于控制其單片機的編寫、掃描并輸入其鍵盤的行列值、顯示其相關的數(shù)碼管動態(tài)運行，將紅外數(shù)據(jù)的通信清晰的展現(xiàn)出來。 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。 關鍵詞： 數(shù)碼管； 單片 機； 紅外 XXXXXXX ii XXXXXXXXXXXXX Abstract How to solve the problem and problem caused by a wide variety of cable cable, creating a safe, convenient, safe environment is people39。s desire. So, the birth of the wireless data transmission mode has changed its traditional technology means .. Because of its low cost, good expansion function, free working conditions and the easy access of advantage, in the field of virtual product market, security alarm system, sensor wireless work system in many aspects has very broad prospects. In order to make the data transmitted in the process of transmission, it can be used for safe and reliable transmission, easy operation, and convenient operation. So it can be used for infrared information technology.. This design mainly by single chip puter 89lpc935 as the design basis, 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.
