Group 1 includes multiple solution difference elements 11, and each solution difference element 11 wherein one end is transmitted by two
Line 12 is coupled on each axle measurer of multiaxial motion system, solves the other end coupling of difference element 11
In filtering serial compressed unit 2；The serial compressed unit of the filtration 2 is provided with filter element 21 and serial
Compressing member 22, filter element 21 are digital signal filter；Distinguish at 3 two ends of transcoding transmission group
With difference element 31 and solution difference element 32 is turned, turn difference element 31 and solution difference element 32 it
Between coupling be provided with two parallel and isometric difference cablings 33, turn difference element 31 with solution difference element 32
It is respectively coupled to the serial compressed unit 2 of filtration and reception decompression device 4；Above-mentioned filter element 21 is used for
The signal noise of the multiple solution difference elements 11 from decoding group 1 is filtered, signal noise comes from multiaxis
The power transmission shaft of motor system is produced when working, and serial compressed element 22 has then been crossed the multiple of noise filtering
The signal of solution difference element 11 gives serial and compression, and relays signal and transmit to transcoding transmission group 3
In turn difference element 31, turn difference element 31 and export that two amplitudes are equivalent and the signal of opposite in phase
To two difference cablings 33, two parallel and isometric difference cablings 33 then couple the external world and there is noise
