VIBROACOUSTIC MEASUREMENT SYSTEM AND TRAIN POSITION MONITORING SYSTEM Russian patent published in 2024 - IPC B61L25/02 G08C19/00 

FIELD: measuring equipment; railway transport.

SUBSTANCE: system of vibroacoustic measurements contains a sensitive element in the form of a single-mode fiber-optic cable with fiber-optic sensors laid in the ground at a given distance from the railway track, each of which is made from the cable itself in the form of loops assembled into coils, or from a single-mode fiber-optic cable in the form of loops assembled into coils, and equipped with an optical coupling for connection with a fiber-optic cable, wherein the sensors are installed at a distance from each other, one side of the fiber-optic cable is made with a sealed plug, and the other side is connected to the input/output of the reflectometer, the other input/output of which is connected to the output/input of the processing unit, wherein the location of the sensors in the ground is tied to the coordinate system of the railway track. System for monitoring the location of the train comprises on-board satellite navigation receivers installed in the head and in the tail of the train, outputs of which are connected to corresponding inputs of on-board controller through geographic coordinates binding unit, input and output of which are connected to the output and input of the locomotive radio station, and an information-control server installed in the control center, corresponding inputs/outputs of which are connected to outputs/inputs of train location data generation unit, stationary radio station and central processor of electric centralization system, as well as a system of vibroacoustic measurements, the reflectometer and the processing unit of which are installed in the control center, wherein the other input/output of the processing unit is connected to the other output/input of the unit for generating data on the position of the train.

EFFECT: high accuracy of locating a train.
