温度测控实验系统的设计

The Design of the Experimental System of Temperature Measure and Control

本实验系统通过单片机AT89C51实现了温度的测量与控制,设有键盘和显示电路,能够实现对温度的设定、修改、清零和显示当前温度值,同时对温度超过上下限时进行报警处理的功能。为学习温度测量与控制的软件编写和程序调试提供了硬件实验环境。

The experimental system of temperature measuring and controling was realized based on the single - chip microcomputer AT89C51. Tile keyboard and display circuit was designed, which can be used for setting and modifying temperature value, resetting and displaying the present temperature value. At the same time the warning circuit was also designed in the system, which can deal with the alarm when temperature exceeds the upper limit and the lower limit. It can provide experimental environment of hardware for study software compiling and program debugging about temperature measure and control.
