    • The present invention is directed to an elevator dispatching system for controlling the assignment of elevator cars. More particularly, the present invention is directed to a method of determining the commencement and/or conclusion of UP-PEAK and DOWN-PEAK periods of operation. For example, for commencing UP-PEAK operation, a lobby boarding count is predicted, based on historical information of the number of passengers boarding the elevators at the lobby. The predicted lobby boarding count is compared with a predetermined threshold value. If the predicted lobby boarding count is greater than the predetermined threshold value, UP-PEAK is commenced. In the preferred embodiment, the predetermined threshold value is a predetermined percentage of the building's population. Additionally, the present invention is directed to a method of adjusting the threshold value based on actual passenger traffic. For example, once UP-PEAK is commenced, the load of the first few elevators leaving the lobby within a predetermined time interval is determined, and the threshold value is adjusted based on their predetermined load. If the determined load is greater than a certain percentage of the elevator car's capacity, indicative of starting UP-PEAK too late, the threshold value is decreased. Similarly, if the determined load is less than a certain percentage of the elevator car's capacity, indicatve of starting UP-PEAK too soon, the threshold value is increased.
    • 本发明涉及一种用于电梯控制电梯轿厢的分配调度系统。 更具体地,本发明涉及确定的挖掘开始和/或操作的UP-PEAK和DOWN高峰时段的结束的方法。 对于实施例,用于开始UP-PEAK手术,大堂登机计数预测,基于旅客登机在大厅的电梯的数量的历史信息。 预测的大厅登机计数与预定的阈值进行比较。 如果预测的大厅登机计数大于所述预定阈值时,UP-PEAK被展开。 在首选实施例,预定阈值是大楼人口的预定的百分比。 另外,本发明涉及调节基于实际客流量阈值的方法。 例如,一旦UP-PEAK开始时,最初的几个电梯离开预定的时间间隔之内到达大厅的负荷确定性开采,并且阈值是基于它们的预定负载调整。 如果确定开采负荷大于电梯轿厢容量的一定百分比,指示开始上行峰太晚越大,阈值下降。 同样,如果确定性开采负荷小于电梯轿厢容量的一定比例,indicatve太早开始UP-PEAK的,阈值增加。
