Abstract
A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.
