US 7,032,716 B2 · Destination selection control for elevator installation having multiple elevator cars

Abstract

The invention relates to a method for controlling an elevator installation with at least one shaft and a number of cars, it being possible to make at least two cars travel separately up and down along a common traveling path and a passenger being able to enter a destination call by means of an input unit disposed outside the shaft and the destination call being allocated to a car in dependence on an allocation assessment. To develop the method in such a way that the transporting capacity can be increased, with the cars which can be made to travel along a common traveling path hindering one another as little as possible, it is proposed according to the invention that, in the case of allocation of the destination call to one of the cars which can be made to travel along the common traveling path, the portion of the traveling path required for serving the destination call is assigned to this car and blocked for the time of the assignment for the other cars. Furthermore, an elevator installation for carrying out the method is proposed.

Dependent claims

Method for controlling an elevator installation with at least one shaft, a number of cars which each have an associated drive and brake, and at least two cars capable of traveling separately up and down along a common traveling path, comprising:

entering a destination call with a travel destination of a passenger by means of an input unit of a control device of the elevator installation disposed outside the at least one shaft;
performing an allocation assessment for each car;
comparing the allocation assessments of all the cars with one another to determine a best allocation assessment;
and
allocating the destination call to the car with the best allocation assessment to serve the destination call, wherein, in the case of allocation of the destination call to one of the cars which can be made to travel along a common traveling path, a portion of the traveling path required by the allocated car to serve the destination call is assigned to the allocated car and the assigned portion of the traveling path is blocked for a time of the assignment for the other cars which are capable of traveling along the common traveling path.

2 more elements

Elevator installation, comprising:

at least one shaft;
a number of cars which each have an associated drive and brake, at least two of said cars being capable of traveling separately up and down along a common traveling path;
input units disposed outside the at least one shaft for entering a destination call with a travel destination of a passenger;
and
a control device for controlling the cars, said control device adapted for:
carrying out an allocation assessment for the individual cars after each time a destination call is entered;
and
allocating the destination call to one of said cars based on a comparison of said allocation assessments,
wherein when the destination call is allocated to one of the cars which are capable of traveling along a common traveling path, a portion of the traveling path required by the allocated car to serve the destination call is assigned to this car and the assigned portion of the traveling path is not accessible during a time of the assignment for the other cars which are capable of traveling along the common traveling path.
