Abstract:
The present invention pertains to 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 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.
Abstract:
Die Erfindung betrifft ein Sicherheitssystem (1) für einen Aufzug (2), enthaltend mindestens eine Steuereinheit, welche in mindestens zwei verschiedenen Betriebsmodi betreibbar ist. Das Sicherheitssystem (1) weist ferner mindestens ein elektronisches Schloss (7) auf, welches mit der Steuereinheit verbunden ist und mit mindestens einem elektronischen Schlüssel (8) verbindbar oder verbunden ist. Die Steuereinheit ist derart programmiert oder programmierbar, dass sie bei bestehender Verbindung zwischen dem elektronischen Schlüssel (7) und dem elektronischen Schloss (8) nur in einem Betriebsmodus einer ersten Teilmenge der Betriebsmodi betreibbar ist und bei nicht bestehender Verbindung zwischen dem elektronischen Schlüssel (7) und dem elektronischen Schloss (8) nur in einem Betriebsmodus einer zweiten Teilmenge der Betriebsmodi betreibbar ist. Dabei ist ein Wartungsmodus nur in der zweiten Teilmenge der Betriebsmodi verfügbar. Offenbart sind zudem eine Aufzugsanlage mit mindestens einem Aufzug (2) und mindestens einem solchen Sicherheitssystem (1) und ein Verfahren zum Betreiben eines solchen Sicherheitssystems (1).
Abstract:
Elevator group control method for the allocation of landing calls, in which method a target value is assigned to a given service time of the elevator group and landing calls are so allocated to elevators that the assigned target value of the service time is realized on the average, the energy consumption of the elevator group being thereby reduced.
Abstract:
An elevator trip based on destinations and activity parameters of a user is planned by a system having an elevator controller of an elevator installation, a storage device storing building plan data and a route planning computer. The user's trip inquiry, including a desired destination and a desired activity parameter, is received by the planning computer. Building plan data is read from the storage device by the planning computer. The current location of the user is determined by the planning computer, which calculates at least one route proposal based on the user's location, the destination and the activity parameter. The route proposal is communicated to the user. Upon receipt of a confirmation that the user selected the route proposal, a control signal identifying a boarding floor and a destination floor is transmitted by the planning computer to the elevator controller. The elevator installation is controlled according to the control signal.

Abstract:
An elevator system includes a primary power source configured to generate a first power. An elevator car includes an energy sub-system embedded therein. The energy sub-system is in electrical communication with the primary power source to buffer the first power and to generate a second power for powering a drive sub-system that drives the elevator car.
Abstract:
A safety system for an elevator that includes at least one control unit, which control unit is operable in at least two different operating modes. The safety system has at least one electronic lock connected with the control unit, and is connectable, or connected, with at least one electronic key. The control unit is programmed, or programmable, in such that, in the presence of a connection between the electronic key and the electronic lock, it is only operable in one operating mode of a first subset of the operating modes and, in the absence of a connection between the electronic key and the electronic lock, it is only operable in one operating mode of a second subset of the operating modes. A maintenance mode is only available in the second subset of the operating modes.
