Elevator system

Abstract

A method for allocating destination calls in an elevator system, said elevator system comprising at least one multi-deck elevator, in which method the passenger gives his / her destination floor by means of a destination call device at the beginning of the journey route, defining the starting point and final point of the passenger's journey route in the elevator system, which method comprises the steps of generating possible route alternatives from the starting point to the final point of the passenger's journey route, determining a cost function containing at least one travel time term, determining the value of the travel time term corresponding to each route alternative in the cost function, calculating the total cost of each route alternative by using the cost function, allocating for the passenger the route alternative that gives the minimum total cost and guiding the passenger to a waiting lobby and / or elevator consistent with the route alternative allocated.

Description

technical field [0001] The present invention relates to the transport of passengers in buildings. More specifically, the present invention relates to a method and elevator system for distributing destination calls in a building. Background technique [0002] Multi-storey buildings are often equipped with multiple elevators, elevators, automatic doors, access control doors and other corresponding components to facilitate the transport and guidance of passengers from one place to another in the building. When traveling in a building, a passenger must make an elevator call in order to reach his / her destination on a target floor. Group control of an elevator system allocates elevators for passenger use according to the situation prevailing in the elevator system and based on established optimization criteria. In conventional elevator systems, call entry (call entry) is arranged by providing each floor of the building with an up / down button by which passengers indicate a desire...

AI Technical Summary

Problems solved by technology

The result is an inaccurate allocation, which means that either the waiting time for the elevator is too long, or that the passengers cannot catch the elevator serving it, leading to a congested situation in the elevator system, a reduction in travel comfort and a reduction in transport capacity

In addition, since the call input device must be placed as close as possible to the elevator, the prior art solution alternatives contain constraints regarding the layout of the elevator system in the building and related to the delivery configuration

The prior art solution alternatives are equally unsuitable for emergency situations such as plant failures or evacuation situations where the routing of passengers in the elevator system must be implemented differently than normal
