Background
The elevator group management system can respond to the calling request of the passenger by properly allocating the elevator, thereby improving the transportation efficiency of the elevator and shortening the waiting time of the passenger. However, when the elevator waiting passengers include special elevator waiting persons, the elevator allocated by the elevator group management system may not be able to take the special elevator waiting persons into the car and the elevator stops inefficiently because the remaining riding space of the elevator cannot meet the demand space of the special elevator waiting persons, thereby causing the transportation efficiency of the elevator to be low.
In order to solve the above problem, the passenger interface device in the exemplary elevator destination entry system disclosed in chinese patent application CN104066667B provides the passenger with an interface for selecting a visual representation of his or her carried items, the controller determines the amount of space required in the elevator car to accommodate the passenger's carried items based on predetermined space information corresponding to the selected visual representation, and the elevator group management system allocates enough space to accommodate the passenger and his or her carried items in response to his or her call request, thereby solving the basic problem of "riding in the car" of the passenger carrying bulky items.
However, when a passenger who carries a bulky article, a passenger who carries a dirt, a passenger who carries a large pet, a passenger who takes a wheelchair or a hospital bed, or the like enters the car and takes an elevator, the passenger may feel uncomfortable to the passenger who takes the elevator together with the passenger, and the passenger may feel bad. Obviously, the invention patent focuses on how to ensure that the special elevator waiting person can smoothly ride the elevator and how to reduce or eliminate the influence of the special elevator waiting person on the elevator conveying efficiency, but does not consider or relate to the elevator riding experience of other passengers riding the elevator together with the special elevator waiting person.
