【正文】 ，無一沒有涉及到紅外通信技術(shù)，所以有不斷的新的紅外通信產(chǎn)品涌進(jìn)市場(chǎng)，重而也推動(dòng)了對(duì)紅外通信技術(shù)的研究和發(fā)展。隨著各種手持式信息終端設(shè)備在我們的工作中頻繁的使用出現(xiàn)，就標(biāo)志著無線通信的時(shí)代已經(jīng)到來，也意味著無線通信這種比傳統(tǒng)的有線通信更加的讓人接受。并且經(jīng)過多年的發(fā)展，有了今天以紅外通訊為核心技術(shù)的藍(lán)牙、紅外、 等無線數(shù)據(jù)傳輸技術(shù) [1]。 在電腦技術(shù)發(fā)展早期，數(shù)據(jù)都是通過線纜傳輸?shù)?，線纜傳輸連線麻煩，需要特制接口，頗為不便 。 關(guān)鍵字 ： 紅外通訊 發(fā)射端 接收端 系統(tǒng) 基于單片 機(jī)的紅外 通訊軟件設(shè)計(jì) 1 II Abstract The development of science and technology, SCM because of its high reliability and costeffective, in the intelligent home appliances, instrumentation and many other areas has been very widely used. The SCM appliance shows the simplistic appearance, functional diversification, superior performance of the development trend. Infrared munication is a means of munication is the use of more. Infrared munication device has the advantages of small volume, low power consumption, strong function, low cost. In family life, tape recorders, audio equipment, airconditioning color TV using infrared munication system. In this paper, the infrared munication equipment based on single chip microputer in modern society to promote the use of the situation and development prospects, and the system is mainly based on the realization principle and the principle of singlechip infrared munication equipment to design the emission that remote control and receiver. The transmitter includes a key input, to control the operation of the motor and the liquid crystal display the receiving end of the display。本文 簡(jiǎn)述基于單片機(jī)的紅外通訊設(shè)備在現(xiàn)代社會(huì)的推廣使用情況和發(fā)展前景，而 系統(tǒng)方面主要基于 紅外通訊設(shè)備的實(shí)現(xiàn)原 理 和單片機(jī)原理來設(shè)計(jì) 發(fā)射即遙控器和接收端。紅外線 通訊 裝置具有體積小、功耗低、功能強(qiáng)、成本低等特點(diǎn)。當(dāng)前單片機(jī)對(duì)家用電器控制呈現(xiàn)出外型簡(jiǎn)單化、功能多樣化、性能優(yōu)越化的發(fā)展趨向。 基于單片 機(jī)的紅外 通訊軟件設(shè)計(jì) 1 A 目 錄 摘要 .................................................................................................................................I Abstract.......................................................................................................................
