<p>PURPOSE:To enable a track circuit boundary to be clearly obtained, by detecting a train in the mutual relation of receiving voltage signal at a plurality of receiving points arranged in close contact with each other. CONSTITUTION:A first receiving point Pa is set at a distance l from a sending end S1, and a second receiving point Pb is set at a distance X0 from the first receiving point Pa. The distance X0 is set to be a distance between the points in close contact with each other, sufficiently shorter than the distance l between the sending end S1 and the receiving point Pa. A receiver 5 is organized by being provided with the circuit 51 multiplied by m of the receiving voltage Vb of the second receiving point Pb, and a circuit 52 to get the difference DELTAV between the correcting receiving voltage mVb and receiving voltage Va obtained at the first receiving point Pa. By monitoring the polarity of the DELTAV or the value, a track circuit boundary for the position of a train coming to can be clearly detected.</p> |
