<p>PURPOSE:To prevent ommision of reception signal in a boundary portion of a guiding line so as to improve the detection accuracy of moving body. CONSTITUTION:A guiding railway line 11 includes guiding lines 111-116 having reception aperture parts a1-a6. In the guiding lines 111-116 reception aperture parts are arranged at an interval in the advance direction (x) of a moving body 3, and receive transmission signals $1 and output reception signals R21-R26. A signal processing circuit 21 is connected to both the guiding lines 11, 12, and the reception signals R11-R16, R21-R26 are inputted. An input signal processing part 211 envelope-detects reception signals respectively to output detection signals U11, U12, V11, V12, W11, W12 and detection signals U21, U22, V21, V22, W21, W22 and a CPU 212 adds the detection signals.</p> |
