摘要： A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.

摘要： This disclosure relates to a system and method for monitoring a sheave bearing condition, and in particular relates to passenger conveyer systems, such as elevator systems, employing the system and method. An example passenger conveyer system includes a suspension member, and a sheave configured to rotate on a bearing. The suspension member is wrapped around at least a portion of the sheave. Further, the system includes a sensor mounted adjacent an end of the suspension member, and a controller configured to determine a condition of the bearing based on an output of the sensor.

摘要： A method of controlling operation of an elevator system (2), the elevator system (2) including a hoistway (4) extending between a plurality of landings (8) situated on different floors (9), and at least one elevator car (6) configured for moving along the hoistway (4) between the plurality of landings (8). The method includes receiving a control input indicating a passenger transport request, wherein the control input comprises at least one passenger transport request parameter; monitoring passengers (30) within or outside the elevator car (6) and determining at least one passenger parameter associated with the passengers (30); comparing the at least one passenger transport request parameter with the at least one passenger parameter; and controlling further operation of the elevator system (2) based on the result of said comparison.

摘要： A method for crowd prediction in an elevator system includes logging the number of calls across a period of time and generating a first time series for an average number of calls; collecting external influence data and generating a second time series for the external influence data; performing a cross-correlation test on the first and second time series; when a cross-correlation between the first and second time series is determined, performing a causality test on the first and second time series; and when a causal relationship between the first and second time series is determined, using the causal relationship to predict an expected number of calls in the elevator system.
