ABSTRACT:
A positive-feedback go
o-go control system for an electric-vehicle ride (10) at an amusement park reliably communicates motion commands, vehicle-presence signals, and vehicle-status signals in the presence of high electrical noise and does so without the addition of expensive add-on equipment. The railway electric-vehicle ride includes an outbus (16) and an inbus (18) running along a railway (14). The positive-feedback go
o-go control system comprises a wayside control board (22) that provides a bipolar pulse-width-modulated command signal (26) to the outbus. A control circuit (24) onboard the electric vehicle receives the bipolar pulse-width-modulated command signal, amplitude modulates it at different frequencies that represent the electric vehicle's intended action, and provides the processed bipolar pulse-width-modulated command signal (30, 32) to the inbus. The wayside control board receives the processed bipolar pulse-width-modulated command signal, bandpass filters the frequency components, and compares the filtered frequency components to predetermined thresholds to detect the presence and intended action of the vehicle.
