Patent attributes
An elevator car control system and method of operation determines occupancy weight based upon motor load. Information on motor load is collected during ascent and descent with loaded and unloaded elevator cars and used to create estimates of occupancy weight based for the full range of motor loads throughout travel within the hoistway. Once the estimates are available the approximate occupancy weight can be determined after each floor stop and appropriate action can be taken. One action is Load Bypass which prevents the elevator car from stopping to load more passengers until occupancy weight decreases. Another action is Nuisance Detection which clears all internal floor calls when occupancy weight indicates no passengers are present. Another action is Load Dispatch which prioritizes a floor for pickup based on demand.
