Item Mathematical Modelling of the Communication Channel between the Rail Circuit and the Inputs Devices of Automatic Locomotive Signalization(Dnipro National University of Railway Transport named after Academician V. Lazaryan, 2019) Hololobova, Oksana O.; Buriak, Serhii Yu.; Havryliuk, Volodymyr I.; Skovron, Ihor Ya.; Nazarov, Oleksii A.ENG: Abstract. In modern practice of operating under traffic safety conditions, the traffic light signal must be transmitted to the locomotive that moves to it, and duplicate in the driver's cab. However, this communication channel is not protected from external interference. In order to prevent the occurrence of code failure, it is necessary to create conditions under which the automatic locomotive signalling system will distinguish between signals with useful information, from signals with false information. The best way to solve this problem at the first stage is to model the devices. Using the simulation tools of graphical environment of simulation modelling Simulink from Matlab software environment, the software model of the communication channel between the railroad and the input devices of automatic locomotive signalling system was constructed. The created mathematical model with the actual parameters allows us to obtain diagnostic signs of a proper condition, on the basis of which the research is aimed at the identification, recognition and definition of various types of malfunctions, failure, damages and defects in the work of the constituent elements of the system and the signal transmission channel of the automatic locomotive signalling system.
