Aiming at the problem that the electric field intensity value of single sensor acquisition is prone to distortion

which affects the accuracy of voltage level identification

study on multi-sensor cooperative fusion identification voltage level is proposed. Firstly

the sensor is non-orthogonal

hierarchically laid out. Then

establish a space vector electric field dimensionality reduction reconstruction model

so that calculate the strongest electric field strength value by fuse data acquired by multi-sensors. Finally

a second-order fitting is carried out on the strongest electric field strength value. voltage level is identified by the parameter. Experimental platform that can control field voltage levels of 10

35

and 110 k V is built up. Collecting data by devices close to the field source.The fitting parameters graphics obtained by data processing show that it can be clearly seen that different voltage levels are concentrated in different locations in three-dimensional coordinate system.
