Embodiment Construction

[0025] figure 1 is a flowchart illustrating a method for managing elevator cars in a multi-car elevator hoistway system, according to one embodiment. In a multi-car elevator shaft system, two or more cars run independently in two shafts, always in the same direction in one shaft, and change shafts eg at the bottom or top floor. In other words, the cars run up in one hoistway and down in the other, and never toward each other. A control system for a multi-car elevator hoistway system allocates and dispatches elevator cars to service landing or destination calls.

[0026] The multi-car elevator hoistway system includes at least one elevator car store. The elevator cars in the at least one elevator car store are used as backup elevators for a multi-car elevator hoistway system.

[0027] At 100, an elevator control of a multi-car elevator hoistway system determines a preferred number of elevator cars for a given time of day. If the current number of elevator cars is below the ...

Abstract

According to an aspect, a method for managing elevator cars in a multi-car elevator hoistway system (200) is provided. The method comprises determining, by the elevator control, a preferred number of elevator cars (204, 206, 208, 210) for a given time of day; and instructing, by the elevator control, at least one elevator car to enter at least one elevator car store (214) or Returning service from at least one elevator car store (214), wherein an elevator car (216, 218) in the at least one elevator car store (214) is used as a backup elevator car (216, 218) for a multi-car elevator hoistway system .

Description

Background technique [0001] In a multi-car elevator shaft system, two or more cars can run independently in two shafts, always in the same direction in one shaft, and change shafts at the bottom or top floor. In other words, the cars run up in one hoistway and down in the other, and never towards each other. A control system for a multi-car elevator hoistway system allocates and dispatches elevator cars to service landing or destination calls. [0002] A multi-car elevator system must be dimensioned such that it can handle both low and high traffic situations. Thus, the challenge of operating a multi-car elevator system is how to operate it economically in all operating conditions. Contents of the invention [0003] According to a first aspect of the invention there is provided a method for managing elevator cars in a multi-car elevator hoistway system. The method comprises determining, by the elevator control, a preferred number of elevator cars for a given time of day; ...
