摘要
为改进机械式实验仪器,即蒸汽压缩式制冷循环实验台的性能缺陷,设计了基于STM32F103的数据采集板卡,提高数据采集的精度和稳定性;采用基于C#语言的实验软件并结合ASP.NET技术实现实验过程自动化和远程实验教学功能。在此对上述功能的实现过程进行必要的阐述并对实验台的重要性能指标不确定度进行了详细的分析。结果表明实验台能满足现有教学实验要求,并对同类实验装置的研发具有一定的参考价值。
In order to improve the performance of experiment platform with vapor compression refrigeration cycle,a data ac-quisition card based on STM32F103 was designed to improve the precision and stability of the data acquisition. The experimen-tal software based on C# language and ASP.NET technology are adopted to realize the experimental process automation and the remote experiment teaching functions. The necessary elaboration on realization process of the above functions is made. The uncer-tainty of the important performance indexes of the experiment platform is analyzed in detail. The results show that the platform can satisfy the requirements of existing teaching experiment and has a certain reference value for research and development of the similar experiment devices.
