Slip ring loose contact is played, and then causes the flash that communicates.Furthermore because the position of brush is inevitable fixed position, and it is logical
Believe that circuit brush is thinner, after long-play, brush wear can seriously cause communication line loose contact.
In the prior art, the phenomenon of loose contact caused by the non-contact slip ring of photo-electric can only solve brush wear, and
Electronic equipment is used in slip ring, it is easier to influenceed by power signal electromagnetic interference, so to solving electromagnetic interference problem
Effect is little, and especially photoelectricity sets centering to require higher, when slip ring is shaken due to the mutation of wheel speed, transmitting dress
Put and misaligned with reception device, in this case it is still possible to the situation of loss of data or mistake can be caused.
