多路音樂對(duì)講門鈴電子信息工程技術(shù)專業(yè)畢業(yè)設(shè)計(jì)畢業(yè)論文-全文預(yù)覽
【正文】 座上。操作電路設(shè)計(jì)在操作電路中，IC1為編碼電路，所有地址腳懸空（三態(tài)地址），1~~10為10個(gè)用戶選擇鍵，按下1表示接通第1個(gè)用戶，按下2表示接通第2個(gè)用戶而本文主要是介紹基于數(shù)字電子基礎(chǔ)上的電子門鈴的設(shè)計(jì)，以純硬件實(shí)現(xiàn)門鈴的功能。要提高住宅、住宅小區(qū)建設(shè)的現(xiàn)代科技水平，推動(dòng)住宅產(chǎn)業(yè)現(xiàn)代化和住宅的改朝換代，就必須充分利用現(xiàn)代建筑技術(shù)、新型建材、環(huán)保節(jié)能技術(shù)，特別是以計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)為特征的信息技術(shù)。也有的是由IC片播放一段電子音樂的。關(guān)鍵詞：對(duì)講系統(tǒng) 編碼 多路復(fù)用AbstractI designed a multichannel music inter system, it can be used in the building and office between residents and visitors to municate. For the multiuser,this system using the encoding and decoding technology,many circuit modules can be reused, simplifying the circuit structure. At the same time, a largescale CMOS integrated circuits is use to hardware encoding, decoding, it make the system is reliable, low cost, simple wiring, has a strong value. In this article I will mainly introduce the part of design of the circuit and receive circuit and fully introduce the whole process of multichannel music inter doorbell system.Key words: doorbell Electron Multichannel practical目錄引言……………………………………………………………. …. .1總體方案……………………………………………………………. 1操作電路設(shè)計(jì)…………………………………………………………2接收電路設(shè)計(jì)…………………………………………………………3芯片功能介紹…………………………………………………………4經(jīng)驗(yàn)總結(jié)………………………………………………………………8附件…………………………………………………………
