Anti-falling pantograph hard point test and performance monitoring sensor
By introducing deformation grooves and anti-detachment parts into the pantograph sensor bracket and using single-headed bolts to connect the anti-detachment plate, the problem of sensor breakage and detachment was solved, achieving safe sensor connection and signal monitoring, and improving the safety and reliability of train operation.

AI Technical Summary
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.
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.
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.
