    • An elevator system includes a control system that determines the amount of load of the car, and that determines the operating speed profile of the car based upon the amount of load in the car. In a particular embodiment, the control system includes a load weighing device and uses the weight of the car to determine the selection between two operating speed profiles: a normal operating speed profile and a reduced operating speed profile. The control system compares the measured live load to a pre-selected threshold, such as the car weight plus twice the percentage balancing multiplied by the rated full load of the elevator system. If this threshold is exceeded, then the reduced operating speed profile is selected. In this way, reduced balancing may be used. The selected percentage balancing may be determined empirically or estimated by taking into account the building size, usage and other operational characteristics.
    • 电梯系统包括确定汽车负载量的控制系统,并且基于汽车中的负载量确定汽车的运行速度曲线。 在特定实施例中,控制系统包括负载称重装置,并使用轿厢的重量来确定两个运行速度曲线之间的选择:正常运行速度曲线和降低的运行速度曲线。 控制系统将测量的实时负载与预先选择的阈值进行比较,例如轿厢重量加上乘以电梯系统的额定满载的百分比的两倍。 如果超过此阈值,则选择降低的运行速度曲线。 以这种方式,可以使用减少的平衡。 所选择的百分比平衡可以通过考虑建筑尺寸,使用和其他操作特性凭经验或估计来确定。
