One embodiment provides a method for optimizing schedules of a plurality of elevators in a building having a plurality of floors, including: receiving, from a user, an indication requesting that an elevator from the plurality of elevators stop at a particular floor, wherein each of the plurality of elevators has a schedule comprising floors where the elevator will stop; identifying the number of users in the elevator waiting area of each of the particular floors where an indication requesting a stop has been received; and updating, in view of the identified number of users at each of the particular floors, the schedule for the plurality of elevators to optimize the stops for the plurality of elevators, wherein the updating comprises dynamically routing the plurality of elevators upon (i) receipt of indications and (ii) identification of the number of users at each of the particular floors.

A group control device according to the present disclosure includes a registration unit, a calculation unit, and a selection unit. The registration unit makes call registration for a boarding floor, a destination floor, and an allocated car when a user makes a hall destination call by a hall destination calling device. The calculation unit calculates an in-car stay time of the user for the hall destination call. The selection unit selects a past hall destination call as an alternative candidate for call registration for a new hall destination call, in a case where the past hall destination call which has already been registered by the registration unit, whose allocated car is different from a car allocated to the new hall destination call, and whose in-car stay time is shorter than the in-car stay time calculated by the calculation unit.

The invention relates to a method for allocating elevator calls in an elevator system (10) comprising at least one elevator (12a-12c), which elevator system (10) is controlled by an elevator control (16) comprising a destination call allocation control, wherein passenger IDs are inputted into at least one I/O-device (20) of the elevator system (10), whereafter based on the passenger ID a destination call is issued comprising the floor of the I/O-device (20) as departure floor and a preset or inputted destination floor as destination floor of the elevator call. According to the invention when a new destination call is issued, it is checked whether or not a destination call is still pending under the same passenger ID, and if a destination call of said person is still pending, either the new call or the pending call is cancelled.

One or more elevators can be more efficiently controlled by considering the then-current spatial capacity of the elevator. Camera images or other sensor data indicative of the occupied space in the elevator are received and processed by a control device to determine whether or not the elevator should stop at a requested floor. If the elevator is determined to lack space for additional passengers, then the elevator can bypass the requested stop and proceed without delay. If space remains, however, the elevator can stop to accommodate additional passengers. Measured spatial capacity can also be used to coordinate the actions of multiple elevators operating within a building.

An elevator operation managing device capable of reducing a switching of passengers at a time of getting on and getting out of a car. The elevator operation managing device includes an in-car position acquisition unit and a car allocation acquisition unit. The in-car position acquisition unit obtains an in-car position of a user based on layout information and a congestion degree obtained in a congestion degree acquisition unit. The car allocation acquisition unit performs a car allocation to allocate the user to the car based on a received boarding floor and destination floor and the in-car position obtained in the in-car position acquisition unit.

A method for controlling an elevator system comprises obtaining images of the inside of an elevator car, detecting passengers in the images, creating graphic passenger models of the detected passengers from the images and determining the number of passengers who may additionally board the elevator car using the passenger models. The passenger models may reflect the actual size of the passengers.

A method of assigning destination call in an elevator group forms chromosomes including genes where each gene is a correlation of a call and an elevator trip, the possible round trips are calculated, each round trip is evaluated for optimization procedure. The calls are assigned to the elevators by the destination call control based on the best chromosome determined.

An elevator system is provided and includes at least one car; driving elements, each of the driving elements being configured to drive a corresponding car from a waiting area from which at least one passenger boards the corresponding car; at least one sensor configured to identify a presence of more than one passenger intending to board a car and in the waiting area and configured to determine a characteristic of the more than one passenger; and a controller configured to drive more than one car to the waiting area when a capacity of the corresponding car is less than the characteristic of the more than one passenger.

An elevator control system, an elevator system, and a control method therefor. The elevator control system includes: a data collection unit configured to receive a call request signal from a machine passenger at each landing, and receive information about the machine to ride the elevator sent by the machine passenger; and a control unit configured to determine whether to accept the call request from the machine passenger based on elevator operating condition and the information about the machine to ride the elevator, and send information about the rules of riding the elevator to the machine passenger after accepting its call request.
