Abstract
PURPOSE: To perform correct detection without being affected from the coupling loss between the induction line and antenna even if it is greatly varied, by detecting the mobile body such as train in forward and backward movement at the mobile body.
CONSTITUTION: The signal from the transmitter on ground is received with the antenna 13 of the receiver at mobile unit, the reception input enters the BPF's 15 to 17, and the f3 to f1 components of the signal are respectively picked up. 30 and 31 are the conversion point pulse generators, and the signal components mentioned above are subject to required processing up to the generators to produce the pulses of leading or trailing depending on the forward or backward of the mobile body. The signal is fed to the AND gates 32 to 35, and when the mobile body goes left, the signal is given to the OR gate 36, and when right, the signal is to the OR gate 37. Further, the required directional signal is fed to FF38 to correctly detect whether the mobile body goes forward or backward.
