Estimating the term…
An elevator system in which an elevator car travels in a hoistway is provided. The elevator system includes an anchor, a tensioning mass, a car-mounted governor (CMG) affixable to the elevator car, a rope and a processing board. The CMG includes idler and traction pulleys and at least one encoder mountable on one of the idler and traction pulleys and configured to generate a signal reflective of rotation of the one of the idler and traction pulleys on which the at least one encoder is mounted. The rope is extendible from the anchor, around the idler and traction pulleys and to the tensioning mass to cause idler and traction pulley rotation when the elevator car travels in the hoistway. The processing board is receptive of the signal and is configured to determine at least a position of the elevator car in the hoistway from the signal.
An elevator system in which an elevator car travels in a hoistway, the elevator system comprising:
A car-mounted governor (CMG) affixable to an elevator car of an elevator system, the CMG comprising:
An elevator car processing board, which is receptive of a signal from at least one encoder mounted on one of idler and traction pulleys of a car-mounted governor (CMG) of the elevator car and from which at least a position of the elevator car in a hoistway is determinable, the elevator car processing board comprising:
