Abstract:
In a method for allocating an elevator in an elevator system, the elevator system including elevator groups, each group including elevators, the elevator groups being formed based on a load unbalance of the elevators, the method includes: detecting received service calls in a predefined time window; evaluating a number of passengers requesting service based on the received number of service calls; selecting, based on the evaluated number of passengers, an elevator group to serve the floor; and allocating an elevator belonging to the selected elevator group to provide service. An apparatus, an elevator system, and a computer program are also disclosed.
Abstract:
A method for indicating a service status of an elevator, an elevator call-out device, and a computer-readable storage medium. Elevator call-out device includes a call-out button for inputting a request to cause an elevator car to move relative to a landing station where the elevator call-out device is located; a visual sign associated with a direction of movement of the elevator car indicated by the call-out button; a control unit configured to: switch the corresponding visual sign from an off state to a normally lit state upon receiving the request to cause the elevator car to move relative to the landing station where the elevator call-out device is located; switch the visual sign corresponding to the direction of movement of the elevator car after stopping to a flashing state in response to an event that the elevator car stops at the landing station where the elevator call-out device is located.
Abstract:
According to an example embodiment there is provided a method for allocating an elevator in an elevator system. The method comprises constructing passenger batch size distributions for each pair of floors in a building based on passenger batch journeys, each passenger batch journey defining at least the origin and destination floor of the journey, the number of passengers relating to the journey and the time of the journey; receiving a call for an elevator; estimating the number of passengers waiting behind the call based on the passenger batch size distributions; and allocating the call to an elevator being able to serve the estimated number of passengers.
Abstract:
A smart elevator control device of this invention is disclosed, comprising: a sensor, mounting aside by the elevator door to sense the number of passengers waiting for the elevator; a central control system, controlling the rise and fall of the elevators. The central control system further comprises a storage and record unit and a setting unit, where the storage and record unit records and stores the number of passengers at every floor at every moment while the setting unit is to adjust the number of passengers waiting for the elevator sensed by said sensor and to set the number of elevators to operate. By means of the central control system and accompanying sensor to sense the number of passengers waiting for the elevator, an elevator is dispatched to the desired floor to carry the passengers, to shorten the waiting time.
Abstract:
An exemplary elevator input device includes a passenger interface configured to allow a passenger to place a call to indicate a desired elevator service. The elevator input device includes a controller configured to interpret any passenger input regarding desired elevator service. The controller identifies which of a plurality of elevator cars will be able to provide the desired elevator service according to a predetermined criterion. The plurality of elevator cars considered by the controller includes every elevator car that is capable of serving the call. The controller is also configured to assign the call to the identified elevator car. With the input device controller assigning the call to an identified elevator car, the dispatching of elevator cars is distributed among controllers of input devices rather than being accomplished at a single group controller.
Abstract:
An elevator system is provided with a remote hall call registering device by use of which an elevator passenger performs a hall call registration in a position at a prescribed distance from a hall. A moving time comparison device compares the predicted moving time Te of the elevator car with the predicted walking time Tw in the case where the floor on which a remote hall call registering device is installed is set as a parking floor. A standby operation go/no go determination device makes a determination as to whether or not to perform a standby operation based on the result of the comparison of the moving time comparison device, and carries out a standby operation after responses to all calls have been finished only in the case where the standby operation go/no go determination device made a determination to the effect that a standby operation should be performed.
Abstract:
A system for controlling the elevators in an elevator system based on passenger presence. The elevator system includes a number of elevators (1A . . . 1H) wherein first sensor members (2, 2A . . . 2H), second sensor members and additional sensor members are arranged in a waiting area of each elevator (1A . . . 1H) on each floor (F, F1, F2, F3 . . . Fn). The first, second and additional sensor members are fitted to give information about the presence and number of passengers waiting to go either up or down for an elevator at least in the waiting area in question. A controller is provided for controlling the elevators. The controller receives information from the first, second and additional sensor members about the presence and number of passengers waiting for an elevator and to control the movement of the elevators of the elevator system utilizing the information received from the first, second and additional sensor members.
Abstract:
Provided are a group control method and a group control device capable of efficiently controlling the operation of elevators in diversified traffic situations and under a variety of specification conditions required for a group management system. A plurality of elevators are placed in service for a plurality of floors, an evaluation index for a newly made hall call is calculated, and the best suited car is selected and assigned to the hall call based on the evaluation index in the group control method of elevators. A waiting time expectation value of all passengers on all floors for each direction, either that have already occurred or that are expected to occur within a predetermined time period, is taken as the evaluation index, the waiting time expectation value being the expectation value for the sum or the average of waiting time.
Abstract:
An elevator group control apparatus performs operation control of a plurality of elevators by detecting a downward traffic flow ratio of traffic flows departing downward from floors higher than a prescribed main floor in the total traffic flow departing from one floor to another. If the downward traffic flow ratio is not less than a prescribed reference value, a standby mode for downward traffic flow is made effective, in which at least one elevator car is caused to be on standby on a floor higher than the main floor and at least one elevator car is caused to be on standby on the main floor.
