智能数字熔点仪设计

Design of the intelligent digital instrument of melting point

阐述了一个以AT89C52单片机为核心的智能数字熔点仪的硬件电路结构及软件设计。该仪器能对被测样品实时温度初熔值和终熔值进行测量、存储和显示,并可通过键盘对被测样品进行自动的升温和降温操作。

The hardware structure and software design of the intelligengt digital instrument of Melting point which takes AT89C52 single chip as the key part is expound. It can measure, store and show sample s initial and last melting point, and we can press keyboard button to make sample hot and cool automatically.
