多傳感器信息融合技術(shù)引起了工業(yè)測量系統(tǒng)的改變,是智能儀表的發(fā)展方向。針對工業(yè)中干擾的特點(diǎn),提出一種基于統(tǒng)計理論的信息融合方法,它采用高等數(shù)學(xué)的方法求解具有多變量約束條件的極值問題,從而得到最小方差的信息融合結(jié)果。以此方法可以提高系統(tǒng)的抗干擾能力和測量準(zhǔn)確度,并通過實(shí)驗測量進(jìn)行了仿真以表明其正確、有效。

Abstract : Industrial measure system has been changed by the technology of multi2sensor information fusion , the technology is the develop direction of intelligent instrument . A method of information fusion based on statistics theory is given against the industrial disturbance and a mathematics method is used to analyse the extreme value
on multi2variable bind station. The mini2variance of information fusion is given.By the use of information fusion , the anti2disturbance ability and measure precision is increased. The correct and the efficacious is proved by the emulation experment .
Key words : variance ; information fusion ; normal disturbance ; extreme value
