A Technique for Diagnosis of the Resistance of Conductive Rail Track Joints

摘要

This study proposes a technique of remotely determining the resistance of conductive joints as components of a complex system of train traffic control with the help of decision diagnostic functions. Complex amplitudes of current and voltage at the beginning and end of rail tracks are proposed for use as primary informative features. The joint resistance equation is derived by solving a system of incompatible equations made up of power polynomials. It is shown that the relative error value can be adjusted by changing the complexity of the joint resistance equation.
