摘要
以单片机AT 89C 51为基础,配以传感变送器、A/D转换器、D/A转换器、调节阀等实现对贮液容器温度的自动控制,同时还设有报警电路,对其温度超过上下限时进行报警处理;设有键盘和显示电路,用来实现温度值的设定、清零和显示当前温度值的功能。
The automatical control of the storing liquid container＇s temperature was realized based on the single-chip microcomputer AT89C51, along with temperature sensor, A/D convertor, D/A convertor, regulating valve, etc. 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. At the same time the keyboard and display circuit was designed, which can be used for setting temperature value, resetting and showing the present temperature value.
