AI Technical Summary

Technical Problem

Existing pantograph hard point testing and performance monitoring sensors are prone to breakage and detachment during long-term use, affecting train operation safety and potentially causing secondary faults such as mechanical jamming and electrical short circuits.

Method used

A pantograph composite sensor bracket designed to prevent detachment is constructed by setting a deformation groove and an anti-detachment part in the sensor housing, and connecting the first and second anti-detachment plates with a single-headed bolt to ensure that the sensor does not detach in the event of breakage. Strain gauges are used to monitor deformation and transmit signals.

Benefits of technology

This effectively prevents sensors from breaking and falling, ensuring safe operation of the equipment, avoiding impact on other equipment, and improving train operation efficiency and safety.
