GUARD – a new system for rail vehicle roll-back detection
Requires no modification to the train’s envelope and no additional power sources.
NOTE: The LEDs are invisible to the human eye
A new variant of GoTRAX vision based navigation system is GUARD – GoTRAX Used As Rollback Detection which is a safety device to fit to trains to detect unintended movement or “roll-back” as mandated for trains using London Underground infrastructure.
GUARD sits behind the windscreen of the driver cab and communicates with the vehicle’s systems sending a current state of movement signal, reversing/not reversing. The system uses pre-defined parameters to determine whether any movement is acceptable and intentional and if not, will send a signal to the vehicle’s systems which may be used to apply the brakes.
Fitting GUARD, or GoTRAX, requires no modification to the train’s envelope and no additional power sources. GUARD is interfaced with the train’s existing systems and can be fitted very quickly with minimal disruption.
