摘　　要：针对开发和检测LED驱动器的实际需要,提出并实现了一种基于虚拟仪器思想的测试系统组建方法,并就系统的设计思想、结构特点和一些实施要点进行讨论,给出具有通用USB控制功能的基础测试模块和测试软件界面,指出应用通用USB仪器的编程控制方法,图表展示了系统的使用和测试结果的分析。Considering the requirements of developing and testing the power-driver of LED, this paper proposes and implements a new way to build testing system with virtual instrument technology. It discusses the design principle, structure characteristics and some key points of the implementation. Several of testing functional module with USB interface and the testing software windows are demonstrated too. A programming method to control instruments with general purpose, the manipulating method and the testing result are illustrated with data plots and data table.
