Abstract:
An apparatus for performing a group control on elevators is disclosed, by which a total operation of the elevators for respective floors of building is controlled. This apparatus includes condition-instruction table which contains a plurality of predetermined control rules being defined by given conditions and given instructions. The apparatus also includes an elevator controller for detecting, in accordance with a specific rule selected from the control rules, a degree of establishment of the given conditions to provide a detected condition, and for generating, in accordance with the detected condition, an elevator control instruction used for performing the group control.
Abstract:
An elevator passenger traffic measuring system distributes passengers whose destination floors cannot be determined to each of origin-destination floor pairs in accordance with an elevator car position, an incoming passenger number and an outgoing passenger number at each floor, and registered car calls, using probability weights for the origin-destination floor pairs which are determined by previous traffic measurements. The system then estimates the number of passengers for each of the origin-destination floor pairs in accordance with the distributed passengers, and the passengers who moved the corresponding one of the origin-destination floor pairs.
Abstract:
With this group control the allocation of elevator cabins or cars to existing storey or floor calls should be timewise optimized and newly arriving storey calls should be immediately allocated. A computer device provided for each elevator computates at each landing or storey, irrespective of whether or not there is present a storey or landing call, from the distance between the storey and the cabin position indicated by a selector, the intermediate cabin stops to be expected within this distance and the momentary cabin load a sum proportional to the time losses of waiting passengers. In this way the cabin load prevailing at the computation time point is corrected such that the expected number of passengers entering and exiting the cabin, derived from the previously ascertained number of entering and exiting passengers is taken into account for the future intermediate cabin stops. Such loss time sum, also referred to as the servicing cost, is stored in a cost storage or memory provided for each elevator. During a cost comparison cycle the servicing costs of all elevators are compared with one another by means of a comparator, and in an allocation storage of the elevator with the lowest servicing cost there can be stored an allocation instruction which designates that storey or floor to which there can be optimumly allocated the relevant elevator cabin.
Abstract:
A method for controlling an elevator where an elevator is allocated for the use of a passenger in a first optimization phase in such a way that a first cost function is minimized, a second optimization phase is performed, in which the route of the allocated elevator is optimized in such a way that a second cost function is minimized.
Abstract:
An elevator swing operation system for use in a building includes a plurality of floors with landings that are grouped into zones. The elevator cars are allocated to service the zones with a default allocation setup or configuration. The allocation of elevator cars to zones can be modified by moving an elevator car from one zone to another in response to a maximum estimated time to arrival being exceeded and a maximum number of elevator cars allowed to change zones not being exceeded. Furthermore, the default configuration or allocation can be restored when the system is in swing operation, an elevator car is parked, and a minimum time for receiving no calls has been exceeded.
Abstract:
An elevator dispatching system includes a plurality of elevator groups, each of the plurality of elevator groups including a group controller and a plurality of elevator cars, each of the plurality of elevator groups serving a respective set of floors; and a redirector configured to receive a service request including a destination floor, and, in the event more than one elevator group serves the destination floor, communicate the service request to the group controllers of the more than one elevator groups, wherein the respective group controllers of the more than one elevator groups are configured to each determine a respective group score, and communicate the respective group score to the redirector, and the redirector is further configured to determine the best group based on the respective group scores.
Abstract:
An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators.
Abstract:
The disclosure relates to a method of controlling a elevator installation with several elevator cages per elevator shaft, wherein a destination call to a desired destination story is actuated on a call input story by at least one passenger and at least one most favorable call allocation for transport of the passenger by the elevator cage from a start story to a destination story is determined for the destination call by at least one destination call control. If at least one disadvantage parameter is set, at least one disadvantage-free call allocation for transport of the passenger by the elevator cage from a start story to a destination story is determined by the destination call control, in which it is possible the start story and call input story or the destination story and desired destination correspond.
Abstract:
An elevator installation for serving at least one floor in at least one building can be modernized, the elevator installation comprising at least one elevator with at least one elevator car and at least one elevator control. At least one destination call terminal for input of at least one destination call and/or for recognition of at least one identification code is installed on at least one input floor. At least one destination call control is installed. The destination call terminal is, for communication of the destination call signal, connected with the destination call control. The destination call control can be connected to the elevator control through a serial interface of the elevator control.
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.
