Title: ELEVATOR INSTALLATION WITH PREDICTIVE CALL BASED ON NOISE ANALYSIS
Abstract:
An elevator installation (1) for a building (2) has an elevator controller (12) to control an elevator car (10) to move from one floor to another floor (L1, L2, L3) of the building (2), a plurality of sensor units (4), and a processing unit (6). Each sensor unit (4) is located on a floor (L1, L2, L3) and configured to generate an electrical signal that is indicative of a noise level in its vicinity on the floor (L1, L2, L3). The processing unit (6) is coupled to the elevator controller (12) and the sensor units (4). The processing unit (6) analyzes received electrical signals to determine if an electrical signal indicates an increased noise level on a floor (L1, L2, L3) on which the sensor unit (4) generating that electrical signal is located, and to detect that a source of noise moves to distinguish it from a non-moving source of noise that may also be responsible for an increased noise level,and generates a control signal for the elevator controller (12) that is indicative of the floor (L1, L2, L3) with the increased noise level. The elevator controller (12) in response to the control signal causes the elevator car (10) to move to the floor (L1, L2, L3) with the increased noise level.
