多传感器信息融合技术引起了工业测量系统的改变,是智能仪表的发展方向。针对工业中干扰的特点,提出一种基于统计理论的信息融合方法,它采用高等数学的方法求解具有多变量约束条件的极值问题,从而得到最小方差的信息融合结果。以此方法可以提高系统的抗干扰能力和测量准确度,并通过实验测量进行了仿真以表明其正确、有效。
关键词: 方差; 信息融合; 正态干扰; 极值
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
