Method for level monitoring with improved accuracy of an elevator car |
摘要 |
<p>A method which provides for level monitoring of an elevator car 12 within a hoistway 14 at a plurality of floors 20 by providing a plurality of sensed signals which is indicative of an elevator position of the elevator car relative to a plurality of targets 16 having a plurality of light absorptive surfaces and a plurality of light interactive regions, the plurality of targets mounted within the hoistway at the plurality of floors. The plurality of sensed signals is processed to provide a leveling variable, a floor number variable and a direction of travel variable which indicate a direction of travel of the elevator car within the hoistway. The leveling variable, floor number variable and direction of travel variable are stored at a remote elevator monitoring central processor. <IMAGE></p> |
