METHOD FOR SIMULATING TRAIN FLOW ALONG A RAILWAY SECTION Russian patent published in 2023 - IPC B61L27/00 

FIELD: railway simulation modelling.

SUBSTANCE: invention is related to methods for modeling movement of trains on a railway section. In the method, with the help of a hardware-software complex, in which a train schedule is set, operational data is obtained, including the characteristics of the incoming train flows, the characteristics of each train and the passing conditions, and auxiliary data and constant data for modeling, including data on the section in form of a set of logically connected data arrays, including data arrays corresponding to block sections, data on speed limits according to the state of the path and the speed prescribed by traffic light readings is entered, after initializing the data, simulation is carried out by changing the state of the section data arrays. While saving the simulation results, the characteristics of each train are set as a composite distributed object in form of a data array, including data on locomotives and cars, which are independent model objects and can interact with an arbitrary number of other model objects, the section data is supplemented with data arrays corresponding to stations, and the data of these arrays include the number and length of tracks, additionally information about the presence of trains on the track and their coordinates is collected, followed by filtering the received data, at the same time regulatory and reference information that is relevant for the considered direction of movement or station is formed, then according to the received and the generated information, on the basis of the hybrid model of the control system, an assessment is made of stability of the current mode of movement on the line or station, taking into account how a change in various parameters will affect the change in operational indicators, based on the results of the assessment, data forecast for the development of the operational situation is formed, taking into account which modeling is carried out modes of passing the train flow along the railway section and control actions at the level of stations and adjacent hauls are decided on.

EFFECT: possibility of expanding the scope and increasing the stability of operation of the means of passing the train flow along the railway section to disturbances associated with operational work and equipment failures.
