    • A method for assigning hall calls to a plurality of elevator cars on the basis of the estimating the time of arrival (ETA) of each elevator car at the floor of the hall call to be assigned. A new hall call is assigned to the car having the lowest ETA. A previously assigned hall call is reassigned to a car having a lower ETA than the car presently assigned to serve the call when the lower ETA is lower by a value T. The average call waiting time (AWT) is calculated using a selected period of time to tabulate the number of calls and cumulative call waiting time, and this calculated value is compared with the desired AWT for the elevator system. The value of T is changed when the calculated and desired values of ETA have a predetermined relationship.
    • 基于在要分配的门厅呼叫的楼层估计每个电梯轿厢的到达时间(ETA)的基础上,向多个电梯轿厢分配门厅呼叫的方法。 具有最低ETA的汽车分配了一个新的门厅呼叫。 先前分配的门厅呼叫被重新分配给具有比目前被分配来服务呼叫的轿厢的ETA低的汽车,当较低的ETA低一个值T时。平均呼叫等待时间(AWT)是使用选定的时间段 列出呼叫次数和累积呼叫等待时间,并将该计算值与电梯系统的所需AWT进行比较。 当计算的和期望的ETA值具有预定的关系时,T的值被改变。

    • A method of assigning hall calls to a plurality of elevator cars in an ETA strategy in which up hall calls are scanned upwardly and down calls downwardly. A hall call floor at which the scan has stopped for the purpose of assigning or reassigning a hall call at the floor is called a "scan floor". The floor of the advanced position of the car being considered for assignment is called the "AVP floor". In order to favor the clustering of closely adjacent stops in a given car, and thus minimize car bunching, when a car has an intervening stop between the AVP floor and the scan floor, either the travel distance between the AVP floor and the scan floor, or the travel distance from an intervening stop to the scan floor, is used to develop a dynamic bias for the ETA of the associated car. The dynamic or variable bias is inversely proportional to the travel distance, i.e., the number of floors, between the relevant floors.
    • 在ETA策略中向多个电梯轿厢分配门厅呼叫的方法,向上和向下扫描向上和向下向上和向下向上扫描向上电梯呼叫。 扫描已停止的门厅呼叫楼层是为了在楼层分配或重新分配门厅呼叫而被称为“扫描楼层”。 正在考虑分配的汽车的先进位置的地板称为“AVP楼层”。 为了有利于在给定轿厢中紧密相邻的停靠点的聚集,并且因此使汽车聚束最小化,当汽车在AVP楼层和扫描楼层之间有中间停止时,AVP楼层与扫描楼层之间的行进距离, 或从中间站到扫描楼的行驶距离用于为相关联的汽车的ETA开发动态偏差。 动态或可变偏压与相关楼层之间的行进距离,即楼层数成反比。

    • An elevator system, and method of operating same, in which emergency back-up service is provided all floors of a building when normal service is degraded, such as due to a dispatcher malfunction, a communication failure between the elevator cars of a bank of cars and a group supervisory controller or dispatcher, failure of the hall call circuits, and the like. When the emergency service is provided, a different initial block of floors is assigned to each elevator car, and as each elevator car completes a round trip its block of assignments are revised in a rotational manner. Thus, all floors are guaranteed service as long as at least one elevator car is operational.
    • 一种电梯系统及其操作方法,其中当正常服务劣化时,建筑物的所有楼层都提供紧急备用服务,例如由于调度员故障,一排汽车的电梯轿厢之间的通信故障 以及组管理控制器或调度员,门厅呼叫电路的故障等。 当提供紧急服务时,向每个电梯轿厢分配不同的初始楼层,并且当每个电梯轿厢完成往返时,其轮转方式被修改。 因此,只要至少一台电梯轿厢正在运行,所有楼层都能得到保证。
