Aiming at the need of detecting the residual current fire monitoring detector, an intelligent test system based on virtual instrument technology was designed. This system was composed of industrial computer, data acquisition card, signal conditioning circuit, three-phase great current generator and pneumatic fixture, etc. Using Lab VIEW virtual instrument(More)
This paper presents an intelligent test system for printed circuit board of control and protective switching device. The optical isolation circuits and signal conditioning circuits are applied in the system to realize signal conversion. PCI-6133 and PCI-6229 are used for data acquisition. Laboratory Virtual Instrument Engineering Workbench is employed to(More)
The measurement of intelligent motor soft starter performance parameter is an important means to develop new product and guarantee product quality. Based on requirement analysis, an automatic measurement system of performance parameter for intelligent motor soft starter based on virtual instrument technology was designed and implemented. This system was(More)
