1. Field of the Invention
The invention relates to pre-allocation of an elevator call. In particular, the invention relates to pre-allocation of an elevator call in an elevator system with destination control.
2. Description of the Related Art
From the point of view of controlling elevator cars, there are two major control arrangements in use today: elevator systems with traditional control and elevator systems with destination control.
In an elevator system with traditional control, controls both external and internal to an elevator car are provided. A passenger first operates the external controls, such as up and down buttons provided at each floor, to select the desired direction. In response to an up or down button pressed at a certain floor, the elevator arrives to pick up the passenger. Once inside the elevator car, the passenger operates call buttons inside the elevator car to choose his/her destination floor.
In an elevator system with destination control, destination control panels (also known as destination operating panels) are provided outside elevator cars (typically at each floor) where a passenger registers his/her destination floor call before entering the car. The system lets each passenger know which car to wait for, instead of everyone boarding the next car. Accordingly, travel time is reduced as the elevator car makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Typically, inside the elevator car there are no call buttons to push, but only indicators that indicate stopping floors. Elevator systems with destination control are typically used in sky-scraper buildings and other large buildings.
While an elevator system with destination control has several advantages over an elevator system with traditional control, the response time of the control system could still be further improved if elevator calls could be pre-allocated, that is, if the allocation of an elevator call could be started even before the passenger has entered his/her destination floor to the destination control panel.
Therefore, an passenger of the present invention is to alleviate the problems described above and to introduce a solution that allows pre-allocation of an elevator call in an elevator system with destination control.
A first aspect of the present invention is a method of pre-allocating an elevator call in which method a first signal is received at an elevator group controller of an elevator system with destination control. The first signal indicates that a passenger is detected to be approaching the elevator system at one of multiple floors associated with the elevator system. In response, allocation of an elevator call for the detected passenger is initiated, wherein the one of the multiple floors is assigned as the departure floor for the elevator call.
A second aspect of the present invention is an apparatus for pre-allocating an elevator call. The apparatus comprises at least one processor, and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform:
receiving, at an elevator group controller of an elevator system with destination control, a first signal indicating that a passenger is detected to be approaching the elevator system at one of multiple floors associated with the elevator system; and
in response, initiating allocation of an elevator call for the detected passenger, with the one of the multiple floors assigned as the departure floor for the elevator call.
A third aspect of the present invention is apparatus for pre-allocating an elevator call. The apparatus comprises:
means for receiving, at an elevator group controller of an elevator system with destination control, a first signal indicating that a passenger is detected to be approaching the elevator system at one of multiple floors associated with the elevator system; and
means for initiating allocation of an elevator call for the detected passenger in response, with the one of the multiple floors assigned as the departure floor for the elevator call.
A fourth aspect of the present invention is a computer program which comprises code adapted to cause the following when executed on a data-processing system:
receiving, at an elevator group controller of an elevator system with destination control, a first signal indicating that a passenger is detected to be approaching the elevator system at one of multiple floors associated with the elevator system; and
in response, initiating allocation of an elevator call for the detected passenger, with the one of the multiple floors assigned as the departure floor for the elevator call.
A fifth aspect of the present invention is an elevator system with destination control which comprises the apparatus of the second or third aspect.
In an embodiment of the invention, a second signal is received at the elevator group controller.
The second signal indicates the destination floor selected by the passenger.
In an embodiment of the invention, in response to the received second signal, the allocation of the elevator call is completed for the detected passenger.
In an embodiment of the invention, the initiation of the allocation of the elevator call comprises assigning an elevator car for the elevator call.
In an embodiment of the invention, the initiation of the allocation of the elevator call further comprises launching the assigned elevator car towards the assigned departure floor.
In an embodiment of the invention, the first signal is received in response to a predetermined event that includes at least one of:
the passenger logs in to an access control system;
a distance sensor of the elevator system at the one of the multiple floors detects the passenger within a predetermined distance from a destination control panel of the elevator system at the one of the multiple floors;
the passenger operates the destination control panel of the elevator system; and
a sensor of the elevator system at the one of the multiple floors detects the passenger being in the process of giving an elevator call.
In an embodiment of the invention, the predetermined event includes the passenger logging in to the access control system, wherein: the passenger is identified based on the logging in; and the elevator call is personalized for the passenger based on the identification.
In an embodiment of the invention, the computer program of the fourth aspect is stored on a computer readable medium.
It is to be understood that the aspects and embodiments of the invention described above may be used in any combination with each other. Several of the aspects and embodiments may be combined together to form a further embodiment of the invention. A method, an apparatus, a computer program or a system which is an aspect of the invention may comprise at least one of the embodiments of the invention described above.
The invention allows pre-allocation of an elevator call in an elevator system with destination control. This means that at least a portion of the computations in elevator call allocation can be performed in parallel with the passenger selecting his/her destination floor, rather than afterwards.
This in turn allows an elevator car being assigned to the passenger faster than in prior art, as the elevator system can respond even before the passenger has completed his/her destination floor selection e.g. by launching an elevator car towards the departure floor of the passenger before the passenger has completed his/her destination floor selection.
The accompanying drawings, which are included to provide a further understanding of the invention and constitute a part of this specification, illustrate embodiments of the invention and together with the description help to explain the principles of the invention. In the drawings:
Reference will now be made in detail to the embodiments of the invention, examples of which are illustrated in the accompanying drawings.
At step 101, a first signal is received at an elevator group controller of an elevator system with destination control. The first signal indicates that a passenger is detected to be approaching the elevator system at one of multiple floors associated with the elevator system.
In an embodiment of the invention, the first signal may be received at step 101 in response to a predetermined event that includes at least one of:
the passenger logs in to an access control system;
a distance sensor of the elevator system at the one of the multiple floors detects the passenger within a predetermined distance from a destination control panel of the elevator system at the one of the multiple floors;
the passenger operates the destination control panel of the elevator system; and
a sensor of the elevator system at the one of the multiple floors detects the passenger being in the process of giving an elevator call.
Accordingly, even though
At step 102, allocation of an elevator call for the detected passenger is initiated in response to the received first signal, wherein the one of the multiple floors is assigned as, the departure floor for the elevator call. In an embodiment of the invention, the initiation of the allocation of the elevator call may comprise assigning an elevator car for the elevator call, step 103. The initiation of the allocation of the elevator call may further comprise launching the assigned elevator car towards the assigned departure floor, step 104.
At step 105, a second signal is received at the elevator group controller. The second signal indicates the destination floor selected by the passenger.
In an embodiment of the invention in which the predetermined event includes the passenger logging in to the access control system, the passenger may optionally be identified based on the logging in, step 106; and the elevator call may then be personalized for the passenger based on the identification, step 107.
It is to be noted that steps 106 and 107 may alternatively be performed before step 105.
At step 108, in response to the second signal received at step 105, the allocation of the elevator call is completed for the detected passenger.
