一种低温单片机测控系统

A System Measuring and Controlling a Lower Temperature with a Computer on Slice

研制了一种采用8031单片机的低温测控系统。AD590将温度信号变为电信号，0804将这一电信号转换为数字信号送入单片机处理，最后送出，以显示检测的温度、控制电加热器。测控温度大于室温小于一百度，在这一温度范围内测控的温度值可任意设定，如果没有给定将要测控的温度，本系统将予以提示。

The system measuring and controlling a lower temperature is developed with a computer on slice 8031. AD590 changes the temperature signal into the electric one and 0804 turns the electric signal into the figure one, then it is inputted to the computer on sloe to be handled. Finally, it is outputted to show the temperature measured and control the electric heater. If the temperature to be measured and controlled is more than the ambient temperature and less than 100, it can be freely set up. Without the temperature set up , the wystem will give a warn.
