Monitoring system of vibration impacts on the structure of overhead catenary of high-speed railway lines

The results of technical solutions proposed by the authors for application during continuous monitoring of vibration impacts in the overhead catenary cables and wires on the high-speed railway line “St. Petersburg - Moscow” (Russian Federation) are described herein. Specialized design of sensor to be attached at the control points on the overhead catenary cables and wires, including the accelerometer of MEMS type and built-in controller is fulfilled. The monitoring results are being processed by the integrated controller directly on the diagnostics site and transmitted via a radio-frequency channel with a specially designated frequency to the data hubs of the line service stations. The results of experiments for vibration-based diagnostics of the overhead catenary on the test site as well as some results of practical application are presented and highlighted in our article. The classification of events, being recorded via the designed diagnostic tool is completed, as well as the ways of improving continuous monitoring system of the railway overhead catenary are outlined based on the results of trial operation.
