Abstract

A method is for determining a status of a track section of a railroad. Each end of the track section is connected to a respective detector. One of the two detectors transmits a current along the rails of the track section towards the other detector and receives a current transmitted along the rails of the track section from the other detector. The track section is further equipped with a computer in communication with the two detectors. The computer calculates an instant value of the status of the track section as a function of an instant vector based on a measure of an intensity of the current transmitted by a first of the detectors as measured by the first detector (Txl1), a measure of an intensity of the current received by the first detector as measured by the first detector (Rxl1) and a measure of an intensity of the current transmitted by the second detector as measured by the second detector (Txl2).

Dependent claims

A method for determining a status of a track section of a railroad, the track section comprising first and second ends and two rails, wherein the first end and the second end are electrically connected to a first detector and a second detector, respectively, the method comprising:

by the first detector, transmitting a current along the rails of the track section towards the second detector and receiving a current transmitted along the rails of the track section from the second detector,
wherein the track section is further associated with a computer and the first and second detectors are in communication with the computer, and
wherein the computer calculates an instant value of the status of the track section as a function of an instant vector of measures that comprises:
a first coordinate corresponding to a measure of an intensity of the current transmitted by the first detector as measured by the first detector;
a second coordinate corresponding to a measure of an intensity of the current received by the first detector as measured by the first detector;
and
a third coordinate corresponding to a measure of an intensity of the current transmitted by the second detector as measured by the second detector.
