MONITORING VEHICLE RESTRAINTS OVER A CONTINUOUS RANGE OF POSITIONS |
摘要 |
<p>Example vehicle restraint apparatus and methods of operating the same are disclosed herein. An example vehicle restraint includes a main body proximate a dock, a vehicle restraint drive unit, and a barrier coupled to the vehicle restraint drive unit and the main body. The barrier is movable relative to the main body between an extended position, a retracted position. and a plurality of intermediate positions between the extended position and the retracted position. A sensor provides a plurality of position feedback signals corresponding to a plurality of sensed positions of the barrier when the barrier moves along the plurality of intermediate positions. A controller receives the plurality of position feedback signals, performs a plurality of comparisons of the plurality of position feedback signals with a stored reference, and generates an output signal based on the compared value.</p> |
