Abstract
An illustrative example elevator sensor device includes at least one sensor supported on a door of an elevator car. The sensor provides an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis. A processor associated with the at least one sensor receives the output and determines at least one characteristic of the movement of the door based on the indication of the movement of the door. The processor also determines a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.
Claims19
An elevator sensor device, comprising:
- at least one sensor supported on a door of an elevator car such that the at least one sensor moves with the door as the door moves relative to another portion of the elevator car, the at least one sensor providing an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis;
- and
- a processor associated with the at least one sensor, wherein the processor is supported on the door, and the processor receiving the output and determining at least one characteristic of the movement of the door based on the indication of the movement of the door, the processor determining a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.
A method, comprising:
- sensing movement of a door of an elevator car along at least one axis by a sensor supported on the door such that the sensor moves with the door as the door moves relative to another portion of the elevator car;
- sensing movement of the elevator car along at least one axis by the sensor supported on the door;
- supporting a processor on the door, the processor determining at least one characteristic of the movement of the door based on sensed movement of the door;
- and
- the processor determining a location of the elevator car where the movement of the door occurs based on the sensed movement of the elevator car.
