【正文】 and control technology appearance, caused traditional the electronic surveying in the principle, the function, the precision and the automaticity has had huge change, caused the scientific experiment and the application project automaticity can obviously enhance. Temperature is one of important parameters in industrial production and scientific experiment course. In metallurgy, machinery, material, chemical engineering, petroleum and the course of heat treatment, the control effect for temperature directly affects service life and the quality of product. Therefore temperature control is the technology of a key in every key of temperature control lies control .Temperature measure is that the more in two aspects of to measure and to technical parison of this respect and the foundation of temperature control ripen. It presents the designing of the analog circuit on LM35 temperature sensor and the editing and the debugging of the whole temperature control circuit .In this paper, it interview the principle of the temperature control circuit, temperature measure circuit, antijamming circuit, frequency power arnplifier and RAMDAC the theory of LM35 chip and voltage parator.Keyword: Temperature control Temperature measure LM35 application Voltage parator目 錄摘要.................................................................. 2目錄...................................................................4緒論...................................................................51溫度控制電路..........................................................6.........................................................6 方案選擇與論證..................................................62基于模擬電路的溫度控制電路............................................8 ...........................................8.....................................................8.....................................................9 LM35精密集成電路溫度傳感器...............................9 三位半LED顯示A/D轉(zhuǎn)換器ICL7107..........................93 溫度信號的檢測和信號調(diào)整..............................................12.....................................12...........................................12 ...........................................13...............................................144 溫度控制電路的設計.....................................................14 控制電路........................................................14 控制系統(tǒng)中的電壓比較技術........................................15 ............................................15..................................................16..........................................175 顯示電路的設計.........................................................18 顯示電路原理....................................................18 顯示電路設計....................................................186總結(jié)....................................................................19..........................................................19.....
