基于MCU新型铁磁性材料特性实验仪的设计与实现

A new type of magnetic material characteristic experimental apparatus based on MCU environment

利用AT89C2051单片微型控制器和无源固态继电器来实现多路切换,采用译码的工作方式,大量节省了I/O资源,通过LED显示,直观地指示仪器所处的各项工作状态。与现有的磁滞回线实验仪相比,最为显著的特点是:由手动机械调整的工作方式,改变为程控电子切换工作方式;便得仪器具有很高的可靠性、稳定性与使用寿命,智能化自动化程度提高,增加了新的实验方式,简化了繁琐的实验操作步骤,简化了实验过程,降低了复杂的计算量,提高了工作效率。

The new instrument uses the AT89C2051 single-chip micro-controller（SCM） and the solid state relay（SSR） to achieve the multi-channel switching method, adopts on the decoding method to save a lot of I/O resources. The LED display can intuitively indicate the working condition which the instrument lays. Compared with the existing experimental instrument, the most salient feature of the news＇s is that the control method changed from the traditional manual mechanical adjustments to program-controlled electronic switching adjustments which makes the new type instrument has higher reliability, stability and longer life, carry the automation degree to a new and higher level increasing various forms of experimental methods, simplifying the operation steps of the complicated experiments, decreasing the complex of calculation, also improving work efficiency.
