Serdyuk T. Improvement of technical service of rail circuits by the automation of control of its parameters on the base of car-laboratory

The object of research is a process of rail circuits' maintenance and control of its parameters with the help of car-laboratory. The purpose of research is improvement of rail circuits' maintenance and decrease of exploit expenditure by the way of automation of control of its electrical parameters. The scientific basis of rail circuits' maintenance is offered on the basis of the advanced mathematical model of transfer of code signals from way's apparatuses to locomotive's devices at the using of received new analytical dependence of electromotive force in reception coils from the code current and electromagnetic interferences in rails. That has allowed us to increase accuracy during measurements from car - laboratory. The advanced mathematical models of traction net have allowed us to take into account action of conductivities between lines on the propagation of harmonics of traction current on the length of feeder zone, to estimate their influence on a work of rail circuits and to determine method ofautomated control of its parameters and sources with the help of car-laboratory. The developed methods and means of the automated control of parameters of rail circuits, current of locomotive signal system and electromagnetic influences in rails with the help of car-laboratory are realized as a hardware-software complex.
