1、論文題目:基于MCS51的多路溫度檢測終端設(shè)計與實現(xiàn)專業(yè):電子與信息工程學(xué)生:張澤鑫簽名:指導(dǎo)教師:倪云峰簽名:摘要溫度是工業(yè)生產(chǎn)過程中保證產(chǎn)品質(zhì)量的重要可控參數(shù)。因此,在工農(nóng)業(yè)生產(chǎn)和科學(xué)研究中溫度的檢測與控制在現(xiàn)代經(jīng)濟(jì)與社會中越來越受到重視。傳統(tǒng)的監(jiān)測方法都是單點測量,同時有溫度傳遞不及時、精度不夠的缺點,不利于工業(yè)控制者根據(jù)溫度變化及時做出決定,因此多路溫度檢測終端的設(shè)計成了一項重要的研究課題。本文設(shè)計了一種基于單片機(jī)的具有多路采集通道的高精度的數(shù)字溫度檢測系統(tǒng)。硬件上,CPU采用STC89C52為主
2、控芯片,配置DS18B20溫度傳感器作為信號采集裝置,利用LCD1602對四路采集的溫度信號進(jìn)行顯示。軟件上運(yùn)用C語言的編程,用protues仿真和硬件電路的設(shè)計,實現(xiàn)了實時溫度檢測,并能夠方便設(shè)置溫度上下限,實現(xiàn)報警功能,另外還配備了單片機(jī)與PC機(jī)的通信功能。文中,終了進(jìn)行了測試與實驗,實驗達(dá)到了預(yù)期的結(jié)果?!娟P(guān)鍵詞】溫度測量;單總線;數(shù)字溫度傳感器;單片機(jī)【論文類型】設(shè)計型-41-Title:TheTerminaldesignandimplementationofmulti-channeltemper
