基于單片機的溫度控制系統(tǒng)畢業(yè)設計

1、I基于單片機的溫度控制系統(tǒng)設計摘要隨著國民經(jīng)濟的發(fā)展，人們需要對各中加熱爐、熱處理爐、反應爐和鍋爐中溫度進行監(jiān)測和控制。采用單片機來對他們控制不僅具有控制方便，簡單和靈活性大等優(yōu)點，而且可以大幅度提高被控溫度的技術指標，從而能夠大大的提高產(chǎn)品的質(zhì)量和數(shù)量。本設計采用無ROM的8031作為主控制芯片。8031的接口電路有8155、2764。8155用于鍵盤LED顯示器接口，2764可作為8031的外部ROM存儲器。其中溫度控制電路是通過可

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