Group call management

Abstract

In elevator journey prioritization often calls for larger groups are prioritized. This is often misused by placing elevator calls for larger groups that are actually travelling. This problem can be reduced by identifying the calling person when placing the call and again in the elevator. The number of people in the elevator can be estimated by using machine vision or weight-based approximation methods. When the number of passengers is not known the possible misuse can be suspected if a person places considerably more group calls as than average.

Description

technical field [0001] The present invention relates to controlling group calls in elevator systems. Background technique [0002] The most traditional method of calling an elevator is to press a button indicating the direction the passenger wishes to travel. However, this is insufficient for today's modern elevator systems when an elevator group may have a large number of elevators with different properties. For example, in the group there may be express elevators with preselected possible destinations. Such systems are often found in large buildings where there is a need for high capacity elevator systems. [0003] The efficiency of elevator systems can be increased by using so-called destination control systems with the possibility to direct a group of people to travel with the person making the elevator call. An elevator call made for more than one person is called a group call. A similar function can be achieved, for example, by asking each passenger to indicate the...

Problems solved by technology

Thus it cannot be used for larger groups or hypothetical calls

Also, if there are more people traveling from the same floor and one person makes an imaginary call, the mechanism doesn't work because someone else will get into the elevator anyway
