Elevator monitoring in shuttle mode

A device configured to monitor a plurality of elevators, wherein at least two of the plurality of elevators are set into a shuttle mode in which the corresponding elevator travels between two pre-defined floors, the device including

• means for calculating at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in the shuttle mode at a predetermined floor;
• means for determining a time required by a user for reaching each of the at least two elevators in the shuttle mode from an operation terminal location;
• means for calculating a preference order of the at least two elevators in the shuttle mode on the basis of the time of arrival and/or departure of the elevator car of each of the at least two elevators in the shuttle mode and the time required by the user for reaching each of the at least two elevators in the shuttle mode from the operation terminal location;
• means for assigning one of a plurality of display modes to each of the at least two elevators in the shuttle mode according to the preference order;
• and
• means for causing displaying of an elevator identification according to the preference order by using the assigned display mode.

An elevator system including

• a plurality of elevators, wherein at least two of the plurality of elevators are set into a shuttle mode in which the corresponding elevator travels between two pre-defined floors;
• at least one operation terminal including a display for displaying information related to the at least two elevators in the shuttle mode;
• a controller configured to
• calculate at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in the shuttle mode at a predetermined floor;
• determine a time required by a user for reaching each of the at least two elevators in the shuttle mode from the location of the at least one operation terminal;
• calculate a preference order of the at least two elevators in the shuttle mode on the basis of the time of arrival and/or departure of the elevator car of each of the at least two elevators in the shuttle mode and the time required by the user for reaching each of the at least two elevators in the shuttle mode from the operation terminal location;
• and
• assign one of a plurality of display modes to each of the at least two elevators in the shuttle mode according to the preference order;
• wherein the at least one operation terminal is further configured to display an elevator identification of the at least two elevators in the shuttle mode according to the preference order and the assigned display mode.
