Algorithms and mathematical model for determining shunt power of intelligent track section control sensor

Abstract

The normal operating state of jointless and butt track circuits depends on the state of change in the insulation resistance; respectively, the correct choice of the maximum and minimum limit resistance characteristics should be considered. The maximum and minimum limit resistance depends on the power consumption of the unlimited track circuit in the normal and the mode of movement of the wheelset at the supply end of the rail line. The article presents a study of an intelligent track circuit without insulated joints, where logical elements replace all the equipment of mechanical and electrical energy converters. The research aims to determine the shunt that affects the definition of the movable block, respectively, the definition of the power of the shunt. The method consists in choosing a sensor, namely an intelligent track control sensor, and developing a mathematical model for determining the shunt power, which provides the influence of the shunt on the track circuit. Research carried out for track circuits with insulating joints has shown that with the value of the argument, modulus, and synthesis of the maximum-minimum limit resistance when the supply end is shunted, the maximum power will be the least minimum Rkmax. Because of the lack of more accurate data for an intelligent control sensor, studies were carried out.
