Abstract
PURPOSE:To enable the electric transmission of information without suffering the disturbance of noise by increasing the number of optical fibers and light emitting elements between a ground position signal setting part and a transmitting light-emitting part, and increasing the number of light receiving elements of a receiving light-receiving part and optical fibers between the light-receiving part and a photoelectric converting part on a vehicle. CONSTITUTION:A marker signal and a ground position signal are always being sent out of a ground position transmitting light-emitting part 3 and, when a train passes through the side of the light-emitting part 3, the receiving light-receiving part 2 of a vehicle-loaded equipment receives the marker signal and the ground position signal. And, the marker signal is outputted from a marker signal generating part 22 to the light-emitting part 3 in accordance with the quantity of information of a ground position signal setting part, and the light emitting body (a) of the light-emitting part 3 repeats the emission of light corresponding to the marker signal. Then, on the vehicle-loaded equipment which received the ground position signal, a marker signal is sent out of a marker signal generating part 19 to the 6 of a transmitting light-emitting part 1 while, at the same time, a set train number and a classified number are sent out from a train classification signal 10 to the 7-10 of the light-emitting part 1, and the light emitting bodies of the 6-10 of the light-emitting part 1 emit by light the first column of the train number synchronized with the signal of the marker signal generating part, followingly emitting light in order and completing transmission.
