毕业论文设计基于51单片机温度控制系统摘要在日常生活中温度在我们身边无时不在，温度控制和应用在各个领域全部相关键作用。很多行业中全部有大量用电加热设备，和温度控制设备，如用于报警温度自动报警系统，热处理加热炉，用于融化金属坩锅电阻炉及多种不一样用途温度箱等，这些全部实行单片机技术，利用单片机语言程序对它们进行控制。而单片机技术含有控制和操作使用方便、结构简单便于修改和维护、灵活性大且含有一定智能性等特点，能够正确控制技术标准，提升了温控指标，也大大提升了产品质量和性能。因为单片机技术优点突出，智能化温度控制技术正被广泛地实行。本文介绍了基于单片机 AT89C51 温度控制系统设计方案和软硬件实现。实行温度传感器 DS18B20 采集温度数据，7 段数码管显示温度数据，按键设置温度上下限，当温度低于设定下限时，点亮绿色发光二极管，当温度高于设定上限时，点亮红色发光二极管。给出了系统总体框架、程序步骤图和 Protel 原理图，并在硬件平台上实现了所设计功效。关键词：单片机 温度控制系统 温度传感器AbstractIn daily life, the temperature in our side the ever-present, the control of the temperature and the application in various fields all have important role. Many industry there are a large number of electric heating equipment, and the temperature control equipment, such as used for alarm automatic temperature alarm systems, heat treatment furnace, used to melt metal crucible resistance furnace, and all kinds of different USES of temperature box and so on, these using single chip microcomputer, using single chip computer language program to control them. And single-chip microcomputer technology has control and convenient in operation, easy to modify and maintenance of simple structure, flexibility is large and has some of the intelligence and other characteristics, we can accurately control technology standard to improve the temperature control index, also greatly improve the quality of the products and performance. Because of the advantages of the ...
