基于VB的超級電容器恒流測試系統的研制

摘要：針對在超級電容器性能測試中需要恒流充放電測試的實際情況，本文設計了一種基于VB語言的恒流充放電測試系統。人機交互界面采用VB語言設計，并應用VB的Mscomm控件實現了電腦與PIC單片機之間的通訊。測試結果表明，該測試系統操作方便，界面友好，可以直觀動態顯示超級電容器兩端的電壓曲線，實現對數據的實時采集和處理，并在測試過程建立詳細的數據檔案。實驗證明，該系統能夠滿足超級電容器大電流恒流測試的需要。 敘詞：超級電容器 人機界面 VB 曲線繪制 Abstract：According to the real situation of testing the constant current power charge and discharge performance for the supercapacitor, this paper introduced a test system which based on VB platform. Application of VB's Mscomm control implements the communication between computer and the microcontroller. Interface program was written by the VB. The testing result showed the System is friendly in human-computer interface and easy to operate. This system can display V-T curve at the supercapacitor, realize acquisition data at real-time and estimation and establish detailing data files for the progress of the testing, and it can save the data.
