用单片机进行温度的控制及LCD显示系统的设计论文编号:JD909 包括开题报告，任务书。 论文字数:14253,页数:45摘 要 温度测量与控制是工程实践中常见的问题,在工业生产中有着广泛的应用。针对此领域的发展方向，本论文设计了一个基于单片机的智能温度测量系统。本系统以AT89C51单片机为微控制器，采用数字温度传感器DS18B20作为测温元件, 温度传感器DS18B20采集温度信号送给单片机处理，单片机再把处理后的温度数据送到LCD上显示出来。 能够实现快速、准确的测温功能和越限声光报警功能。本论文完成了系统硬件电路的设计，给出了软件流程框图，并编写了相关的软件程序。 关键词：温度测量；传感器 ；单片机；LCD显示 Abstract Temperature measuring and the controlling are very common in the project practice and are widely adopted in the industry production . In view of development direction of this domain, this paper introduces a temperature measuring system which take the AT89C51 single chip microcontroller as an controlling unit and the digital temperature sensor --DS18B20, as temperauture measuring transducer. The collected temperature signals of the digital temperature transducer--DS18B20 are processed by the single chip microcontroller. The processed temperature signals are displayed on the system has achieved prompt and precise temperature measuring and the super warnning function by sound and light .This paper has finished the design of hardware curcuit and compiled related software program..
