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
