ROLLING STOCK DERAILMENT CONTROL SYSTEM Russian patent published in 2023 - IPC G01D5/353 B61L25/02 

FIELD: railway equipment.

SUBSTANCE: means of ensuring safety in railway transport, namely devices for monitoring the derailment of rolling stock. The rolling stock derailment control system contains at least one control sensor, including n sensitive elements arranged in series, each of which is made of the same single-mode optical fiber in a protective sheath in the form of a coil of m loops, mounted on a corresponding plate at the edges in which one ends of the torsion springs are rigidly attached, inside which the axis of rotation is installed, and the other ends of the torsion springs are rigidly attached to the under-rail tire, located perpendicular to the rails in the inter-rail space and on both sides of them. In this case, the ends of the optical fiber of the control sensor are connected via an optical coupling to a single-mode fiber of the main fiber-optic cable laid between stations in the ground along the railway track, one end of which is connected to a sealed plug, and the second is connected through an optical switch to a reflectometer, the output of which is through the module processing is connected to the input of the event identification module, the output of which is connected to the hardware-software device of the station duty officer, while the reflectometer, processing module and event identification module are installed in the station premises.

EFFECT: increasing the accuracy of rolling stock derailment control.
