Virtual instrument for calibrating of multi-sensor testing system based on LabWindows/CVI

摘要

In multi-sensor multi-parameter testing system, the mapping relation between inputs and outputs of the system must be built with calibrating data. In this paper, typical methods used to build this mapping relation are gathered and embed in a virtual instrument based on LabWindows/CVI. After data fusion has finished, instrument reports the fusion result to user. This made what user need to do are adding the path of file, in which calibrating data is saved, and choosing data fusion method, but not deep-seated understanding to data fusion methods. So repetitive development about data fusion can be avoided, the applying of data fusion can be broadened, and the development process of multi-sensor system can be accelerated.
