Abstract
The utility model provides a remote anti-interference transmission device which comprises a host machine, a sub machine and a signal current transmission line arranged between the host machine and the sub machine, wherein the sub machine is distributed along the path of the signal current transmission line and kept in a certain distance from the signal current transmission line, the sub machine comprises a signal inducing element, and the distance is within the range where the signal inducing element can induce the signal current transmitted by the host machine. Since the host machine and the sub machine are in a non-contact connection, without producing a loading effect and the signal current transmitted by the host machine doesn't cause the situations of shunt and attenuation, the effect of remote transmission is achieved. Additionally, the current transmitted on the signal current transmission line doesn't cause the transmission signals to be attenuated due to the shunt effect resulting from the increase of the sub machine, so that an approximately infinite number of sub machines are allowed to be arranged beside the signal current transmission line.
