Abstract
The invention relates to an elevator system comprising: a plurality of elevator sub-systems and a group controller configured to control the plurality of the elevator sub-systems, wherein the group controller is configured to: determine an efficiency of the elevator system; and control, in accordance with the efficiency of the elevator system, at least one elevator sub-system to serve elevator calls at different zones from at least one other elevator sub-system. The invention also relates to a method, a group controller and a computer program product.
Claims17
An elevator system comprising:
- a plurality of elevator sub-systems, each elevator sub-system comprising at least one elevator car arranged to travel in a loop path comprising a first vertical section and a second vertical section connected to each other with two horizontal sections, wherein the at least one elevator car is configured to travel upwards in the first vertical section of the loop path and downwards in the second vertical section of the loop path,
- a group controller configured to control the plurality of the elevator sub-systems,
- wherein the group controller is configured to:
- determine an efficiency of the elevator system, and
- control, in accordance with the efficiency of the elevator system, at least one elevator sub-system to serve elevator calls at different zones from at least one other elevator sub-system.
A method for controlling at least one elevator sub-system of an elevator system, the elevator system comprising:
- a plurality of elevator sub-systems, each elevator sub-system comprising at least one elevator car arranged to travel in a loop path comprising a first vertical section and a second vertical section connected to each other with two horizontal sections, wherein the at least one elevator car is configured to travel upwards in the first vertical section of the loop path and downwards in the second vertical section of the loop path,
- the method comprises:
- determining an efficiency of the elevator system and
- controlling, in accordance with the efficiency of the elevator system, at least one elevator sub-system to serve elevator calls at different zones from at least one other elevator sub-system.
A group controller comprising:
- at least one processor;
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the group controller to perform:
- determine an efficiency of the elevator system, and
- control, in accordance with the efficiency of the elevator system, at least one elevator sub-system to serve elevator calls at different zones from at least one other elevator sub-system.
