Abstract:
The present invention discloses a solution for allocating hall calls in an elevator system (X, Y), which comprises call input devices (110, 210) for registering hall calls at the floors (F0 - F10), a group control system (101, 201, 301, 304) responsive to said hall calls, and a number of elevators (A, B, C, D) controlled by elevator-specific elevator controllers (120, 303) on the basis of commands issued by the group control system (101, 201, 301, 304). A number of route alternatives (302) are generated on the basis of the calls active, and allocation calculation is decentralized by calculating elevator-specific cost terms associated with the route alternatives (302) in the elevator controllers (120, 303). The cost terms are returned to the group control system (101, 201, 301, 304), which allocates the hall calls to the elevators (A, B, C, D) according to the route alternative (302) giving the lowest allocation cost.
Abstract:
Die Erfindung geht aus von einer Aufzugssteuerung einer Aufzugsanlage (10; 10') mit zumindest zwei Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30'), die dazu vorgesehen sind, unabhängig voneinander in einem gemeinsamen Fahrschacht (14, 16, 18; 16') verfahren zu werden, und mit einem Steuergerät (12; 12'). Es wird vorgeschlagen, dass das Steuergerät (12; 12') dazu vorgesehen ist, einen definierten Mindestabstand zwischen jeweils zwei aufeinanderfolgenden folgenden Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36, 26', 28', 30') und einen definierten Maximalabstand zwischen jeweils zwei aufeinander folgenden Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30') einzuhalten.
Abstract:
The present invention discloses a method for optimal routing of the elevators in an elevator system in a situation where the supply power received by the system is limited e.g. due to emergency power operation. In the invention, routes are optimized by using a cost function to which has been added a term containing the summed instantaneous power consumed. Power consumption is monitored in real time, and the elevators need a start permission from the control system. A route alternative that exceeds the power limit is penalized in the cost function by a so-called penal term. With the elevator routing obtained as a result, the instantaneous power consumed by the system remains continuously below the set power limit. Some call can thus be postponed to be served later. By the method of the invention, the number of elevators serving passengers in an emergency power situation can be varied dynamically .
Abstract:
The invention relates to a procedure for controlling an elevator group consisting of double-deck elevators. According to the invention, landing calls are allocated to the elevators and after that to the elevator decks in such a way that the passenger journey time is optimised. The procedure of the invention takes into account the time the call has been on and the estimated time of arrival to the destination floor.
Abstract:
Elevator system (8) , which comprises one or more passenger elevators (2) and at least one special elevator (3) and call pushbuttons (5, 7) for reserving the elevator (2, 3) for use by passengers. The system further comprises a control system (9) , which is arranged to allocate a special elevator (3) as a response to a call received from a call pushbutton (7) of a special elevator and to allocate a passenger elevator (2) or a special elevator (3) to a user as a response to a call received from the call pushbutton (5) of a passenger elevator. In the method for controlling an elevator system a special elevator (3) is allocated in the elevator control system (9) as a response to a call received from a call pushbutton (7) of a special elevator, and a passenger elevator (2) or a special elevator (3) is allocated in the elevator control system (9) to a user as a response to a call received from the call pushbutton (5) of a passenger elevator.
Abstract:
The present invention discloses an extension to a prior-art genetic algorithm, with which the routing of elevators based on the calls given in an elevator system is formed. A new type of gene, a so-called run type gene, is connected to the chromosome of the genetic algorithm according to the invention, with which gene the desired speed profile for the elevator trip can be set. In this way e.g. an upper limit can be set for the acceleration or for the maximum travel speed of the elevator. By means of the run type gene a kinetic energy term is included in the optimization. The energy consumed by the system can thus be minimized more effectively by means of the algorithm, because the varying travel speeds of the elevators create more freedom of choice for the chromosomes of the algorithm.
