METHOD FOR MONITORING THE STATE OF A RAIL LINE AND A SYSTEM FOR INTERVAL CONTROL OF TRAIN MOVEMENT ON A HAUL Russian patent published in 2022 - IPC B61L3/20 

FIELD: traffic control systems.

SUBSTANCE: invention relates to means of interval control of movement. In the method, the track generator signal is supplied to the rail line at the transmitting end, is received by the track receiver and/or locomotive receiver of the train occupying this circuit, signal level is compared with preset threshold levels corresponding to rail vacancy, occupying and breakage conditions. Tolerances for said threshold levels are calculated in advance by mathematical models of track circuits. At the same time, on the locomotive, the calculation results are stored in the database of the control device, in the process of controlling the locomotive, the corresponding data are periodically selected from the database, in real time, and based on results of measurements of values of corresponding parameters, from this locomotive, and results of measurements of corresponding parameters made in equipment of centralized automatic blocking and/or on locomotive in front of train, and transmitting measurement results to the locomotive of this train, changing the threshold levels of the locomotive receiver to control its accuracy in determining said conditions of the rail line. Coordinate of the locomotive front cabin location of this train is measured on its locomotive, the coordinate of the tail car of the ahead train is determined on the locomotive in front of the train, and the coordinate of the generator of the feeding end of the current rail circuit and its output voltage and current, as well as the conductivity of the track ballast of the current rail circuit are determined in the centralized automatic blocking equipment.

EFFECT: increased reliability of determining the states of the rail line in front of the train.
