Abstract

PURPOSE:To realize a simultaneous transmission of the two independent signals of the same frequency, by installing the transmitter/receiver between the intermediate tap and the secondary side of the high frequency transformer connected to the parallel 3-wire type inductive line and providing two sets of the transmitter/receiver to the travelling object. CONSTITUTION:High frequency transformer 10 is connected to parallel 3-wire type inductive lines 1-3 which are laid along the path of the travelling object. Then fixed transmitter/receiver 9 is installed at the secondary side of transformer 10 along with fixed transmitter/receiver 4 provided between the intermediate tap and inductive line 2. The travelling object incorporates bar-type magnetic core antenna 5 which is set vertically to each inductive line with the center set onto line 2, transmitter/receiver 6, loop antenna 7 which is parallel to the surface of the inductive line with the longer side crossing vertically the position right above line 2, and transmitter/receiver 8 each. The current supplied from transmitter/receiver 4 is not coupled to transmitter/receiver 9 and antenna 7 but coupled to antenna 5. Thus the transmission is possible to transmitter/receiver 6. On the other hand, the current from transmitter/receiver 9 is not coupled to transmitter/receiver 4 and antenna 5 but coupled to antenna 7 to secure the signal transmission to transmitter/receiver 8. And no mutual coupling is given between the currents of antennas 5 and 7, thus causing no interference even with the same frequency.
