基于单片机的水浴温度检测系统的软件设计

摘要：温度在工农业和现代科学研究开发的各个领域中是一个非常普遍和常用的测量参数。例如：在冶金工业、化工生产、电力工程、造纸行业、机械制造和食品加工等诸多领域中，人们都需要对各类加热炉、热处理炉、反应炉和锅炉中的温度进行控制和检测。
本次设计以STC89C52单片机作为检测核心,通过硬件电路的制作和软件程序的编制，实现一个温度测控系统.通过铂热电阻组成的电桥对温度进行采样，采样后的电信号通过ICL7650放大，再将信号通过ADC0804进行AD转换后传入单片机进行处理。
本论文给出了各个系统模块的设计思想和硬件框图，详细介绍了系统的软件设计。这个温度检测系统能够准确地进行数据的采样转换，稳定进行恒温的检测过程，并且能够较好地满足对系统精度的要求。

Software design for the system of bathing temperature

Abstract: The temperature is a very widespread and in common use diagraph parameter in the each realm of the work agriculture and modern science research development. For example:In metallurgy industry, chemical engineering produce, electric power engineering, deckle profession, the machine many realms such as manufacturing and food processing etc., the people all need to carry on the controls and examination to the each kind of heating stove, the hot processing stove, reactor and temperature in the boiler.
This time designs to examination the core with a machine of STC89C52 conduct and actions,through the hardware electric circuit manufacture and the software procedure establishment, realizes a temperature observation and examination system.The system spread the feeling machine to come to indirectly to measure the water temperature through a hot electric resistance, make use of to give or get an electric shock the bridge electric circuit to make it from the temperature change but causable electric resistance of variety change becomes the variety of the electric voltage, then pass the ICL7650 to carry on enlarge to the electric voltage signal that the sample come in, use a pair of integral calculuseses type ADC0804 to enlarge of electric voltage signal carry on the conversion of AD,then put them in the unit of STC89C52 to deal with it.
This system according to a design thought for turn of mold, completed the design of the system hardware part, give the design thought and block diagrams of the each system mold piece. This temperature regulating system can steer the sample switching of the figure accurately, the stability steers to heat, the examination process of the constant temperature, and can compare goodly request of satisfaction to accuracy of system.
