Abstract
Disclosed is an elevator system having a first sensor in communication with an elevator in a multi-level hoistway, wherein during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway.
Claims18
An elevator system comprising:
- a first sensor in communication with an elevator in a multi-level hoistway,
- wherein
- during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and
- the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway;
- and
- a plurality of sensors including the first sensor and a second sensor, the first sensor in communication with the elevator and the second sensor in communication with an elevator counterweight in the hoistway,
- wherein
- during an emergency the elevator instructs the plurality of sensors to sense conditions and transmit sensor data representing the sensed conditions, and
- the transmitted sensor data is processed to obtain at least one image of the intensity of the hazard conditions on at least a subset of levels serviced by the multilevel hoistway.
