基于單片機的數(shù)字溫度計的設(shè)計

 摘要：隨著社會的不斷發(fā)展，人們對新科技的需求量也日益增加。在講求新元素的同時，還講求方便、快捷、精準(zhǔn)。溫度計，人們需要對各種加熱爐、熱處理爐、反應(yīng)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、應(yīng)用范圍廣和測溫準(zhǔn)確，其輸出采用數(shù)字顯示，方便讀取。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)品的數(shù)量和質(zhì)量。該種溫度計的控制器采用AT89C51單片機為主控器件，DS18B20為測溫傳感器通過4位共陽極LED數(shù)碼管串口傳送數(shù)據(jù)，實現(xiàn)溫度顯示。

    Abstract:With the continuous development of society, the people of the new technology of demand also increases increasingly. In seeking new elements at the same time, also be convenient, fast, accurate. Thermometer, the people need to all kinds of heating furnace, heat treatment furnace, in the reactor and the boiler the temperature monitoring and control.MCU to use them to control not only has the convenient control, wide application range and accurate temperature measurement, the output of the digital display, easy to read. It can greatly increase the temperature was charged with the technical indicators, which can greatly improve the quantity and quality of products. The thermometer controller using AT89C51MCU as the main controller,S18B20temperature sensor through a total of 4digital tube anode LED serial transmission of data, temperature display.
