Technique of measurement of ultra-low resistance of current conductive junction of rail lines as the problem of states object identification

Abstract

Abstract. Systems of railway automation and remote control play an important role in transportation process ensuring the safety of train traffic, so it is necessary to eliminate failure and malfunctions of all its components and devices. Article deals with the principle of measuring of current conductive junctions rail lines, which allows to carry out the measurement and calculation of the resistance in a wide range of variation (from tens micro-ohm to unit ohm). The presented mathematical models of informative signs can be in automated complexes of diagnostic resistance of current conductive junctions' rail trunk lines, industrial railways, tram road and underground rail.
