Abstract
PURPOSE: To make it possible to detect the position of a traveling body with accuracy by obtaining from 1st and 2nd phase difference detecting circuits the output of a level corresponding to a position in the two-intersection interval of induction lines.
CONSTITUTION: As for a unit by which a traveling body running a constant track detects its own position, intersection type two-wire induction lines 1 of the facility of a ground station intersect at every boundary point of each section obtained by dividing the track by constant length l and have one terminal terminated by a resistance. From the other terminal of line 1, a signal obtained by modulating 7 a carrier of specific frequency fO by its 1/n-dividing wave is fed. The traveling body, on the other hand, is equipped with circuit 22 which detects the phase difference between a composite value of the inputs of antennas 10 and 11 through phase shifters 12 and 13 and a reference phase signal, and circuit 24 which detects the phase difference the composite value and a signal obtained by phase-shifting the reference signal by a constant value. From circuits 22 and 24, the outputs of levels corresponding to a position in the two-intersection interval of line 1 are obtained, so that the position of the traveling body can be found with accuracy.
