Paper Abstract

In order to eliminate the noise and information coupling in the sensing information of the multi-sensor information measuring system, the paper propose a new modeling method, which adopts a distributed sensing mode, uses wavelet multiscale method and multivariate interpolation decoupling approach based on multiscale characteristic respectively in the de-noising and decoupling of sensing information, then uses scalars weighting method under minimum variance to estimate each sensor's contributing rate, and finally obtains the optimal fusion estimation of multi-sensor information. The experiments on the liquid component measurement in complex environment indicate that the precision of the modeling method can reach ±1.5%.
