Abstract
An independent cart system includes an inductive link for contactless power transfer between a track and each mover as the mover travels along the track. A system for contactless data transmission between movers and a controller in the independent cart system includes a transmitter and/or receiver mounted on each mover and a complementary receiver and/or transmitter mounted on a track. The transmitter receives data to be transmitted across the inductive link and modulates a voltage present on either the primary or secondary winding to which it is coupled. The modulated voltage present on one winding induces a corresponding modulation on the voltage present on the other winding. A receiver operatively connected to the other side of the inductive link detects the modulated voltage and decodes the data from the modulated voltage received across the inductive link.
