基于單片機(jī)的溫度控制系統(tǒng)畢業(yè)設(shè)計(jì)

1、I基于單片機(jī)的溫度控制系統(tǒng)設(shè)計(jì)摘要隨著國(guó)民經(jīng)濟(jì)的發(fā)展，人們需要對(duì)各中加熱爐、熱處理爐、反應(yīng)爐和鍋爐中溫度進(jìn)行監(jiān)測(cè)和控制。采用單片機(jī)來(lái)對(duì)他們控制不僅具有控制方便，簡(jiǎn)單和靈活性大等優(yōu)點(diǎn)，而且可以大幅度提高被控溫度的技術(shù)指標(biāo)，從而能夠大大的提高產(chǎn)品的質(zhì)量和數(shù)量。本設(shè)計(jì)采用無(wú)ROM的8031作為主控制芯片。8031的接口電路有8155、2764。8155用于鍵盤(pán)LED顯示器接口，2764可作為8031的外部ROM存儲(chǔ)器。其中溫度控制電路是通過(guò)可

2、控硅調(diào)功器實(shí)現(xiàn)的。雙向可控硅管和加熱絲串聯(lián)接在交流220V，50HZ交流試點(diǎn)回路，在給定周期內(nèi)，8031只要改變可控硅管的接通時(shí)間便可改變加熱絲功率，以達(dá)到調(diào)節(jié)溫度的目的。關(guān)鍵字：溫度控制；接口電路；可控硅DesignofTemperatureControlSystemBasedonSCMLibing(CollegeofZhangjiajieJishouUniversityJishouHunan416000)AbstractAlongw
