APPARATUS AND A METHOD FOR ELEVATOR ALLOCATION USING A MAGNETIC FIELD MAP IN AN ELEVATOR SYSTEM

摘要

The invention relates to a method and apparatus. In the method a target area is divided to a plurality of cells. A plurality of movement paths of mobile nodes are determined, each movement path comprising an origin cell and a target cell, the origin cell and the target cell being determined using a magnetic map of the target area. The durations of the plurality of movement paths are determined for an elevator user. A route topology data structure is formed using the plurality of movement paths and the durations of the plurality of movement paths, the data structure comprising for a plurality of cells an estimated time to reach an elevator location. An elevator call in a request cell is determined by a requesting mobile node. The time to reach the elevator location is determined using the data structure and information on the request cell, and an elevator car is selected to serve the elevator call based on the time to reach the elevator location, current positions of at least two elevator cars, and current directions of at the least two elevator cars.

1. A method, comprising:
dividing a target area to grid having a predefined resolution, the grid comprising a plurality of cells; determining a plurality of movement paths of a plurality of mobile nodes, each movement path comprising an origin cell and a target cell, the origin cell and the target cell being determined using a magnetic map of the target area; determining durations of the plurality of movement paths for an elevator user; forming a route topology data structure using the plurality of movement paths and the durations of the plurality of movement paths, the route topology data structure comprising for the plurality of cells a time to reach an elevator location cell; determining an elevator call in a request cell by a requesting mobile node, the request cell being the cell in which the elevator call is made; determining the time to reach the elevator location cell using the route topology data structure and information on the request cell; and selecting an elevator car to serve the elevator call based on the time to reach the elevator location cell, a floor of the elevator location cell, current positions of at least two elevator cars, and current directions of at the least two elevator cars.
