DEVICE FOR MONITORING ROLLING STOCK Russian patent published in 2023 - IPC B61L3/04 B61L23/00 

FIELD: railway equipment.

SUBSTANCE: means for monitoring derailment and violation of the lower clearance of rolling stock. The device contains collapsible type sensors installed on the railway track, an optical integrity monitoring cord with at least one optical fiber. In this case, the optical fiber forms a closed optical path connected via a fiber-optic communication line to a remotely installed device for reading the state of the sensors and generating signals on the operation of the sensor. In this case, the closed optical path is formed by an optical fiber loop connected via a fiber-optic communication line to a remotely installed device for reading the status of the sensors, or the optical cord for monitoring the integrity of the sensors is connected at one end to the optical signal reflector to form a closed optical path, and at the other to the optical circulator, connected to the optical source module and the photodetector module.

EFFECT: simplification of installation is achieved, eliminating the influence of traction and stray currents.
