Abstract:
An controlling apparatus for a double deck elevator is disclosed. An allocation control unit (5), when a predetermined specified floor is registered in an elevator hall call registering unit (4) in a double operation mode, makes both of upper and lower cages of each double deck elevator respond thereto. Each cage call registering unit (9) is capable of registering a cage call to both of the upper and lower cages in the double operation mode as far as the specified floor is concerned. An operation control unit (8) in each elevator controls operations of the upper and lower cages to respond to the elevator hall call to the specified floor which is allocated by the allocation control unit (5) and to a cage call to the specified floor which is registered in the cage call registering unit (9).
Abstract:
A system for allocating hall calls in a group of elevators includes a plurality of neural network modules to model, learn and predict passenger arrival rates and passenger destination probabilities. The models learn the traffic occurring in a building by inputting to the neural networks traffic data previously stored. The neural networks then adjust their internal structure to make historic predictions based on data of the previous day and real time predictions based on data of the last ten minutes. The predictions of arrival rates are combined to provide optimum predictions. From every set of historic car calls and the optimum arrival rates, a matrix is constructed which stores entries representing the number of passengers with the same intended destination for each hall call. The traffic predictions are used separately or in combination by a group control to improve operating cost computations and car allocation, thereby reducing the travelling and waiting times of current and future passengers.
Abstract:
An elevator control apparatus capable of predicting reversion floors of elevator cages accurately. The control apparatus comprises a neural network, in which traffic state data are fetched into the neural network, so that predicted values of floors where the moving direction of each cage is reversed are calculated as predicted reversion floors. In the elevator control apparatus, reversion floors near true reversion floors can be predicted flexibly correspondingly to traffic state and traffic volume.
Abstract:
A method and apparatus for group-supervising an elevator system according to this invention consists in predicting the position of operating cages after the lapse of a predetermined time, detecting an unoccupied cage and tentatively setting the standby position thereof, so as to predict the position of unoccupied cages after the lapse of the predetermined time under the condition that the detected unoccupied cage is run to the set position and is caused to stand by there, predicting, from the positions of the cages, the number of cages which will lie in certain floors or certain floor zones after the lapse of the predetermined time and estimating the numbers of cages in association with the floors, whereby the floor in which the unoccupied cage is to stand by is selected.
Abstract:
In an elevator system in which an elevator car serves a plurality of floors in response to hall calls and cage calls, the number of, for example, up hall calls originated from, for example, the 2nd floor is counted, and the number of cage calls, classified by destination floors, registered in the elevator car after the elevator car has served each of the up hall calls is also counted. The count of the hall calls and the count of the cage calls classified by destination floors are compared with each other, and, on the basis of the result of comparison, the probabilities of origination of cage calls, classified by destination floors, which will be registered in the elevator car after the elevator car has subsequently served a new up hall call which would be originated from the 2nd floor, are calculated for forecasting future cage calls.
Abstract:
An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of floors of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable elevator car for servicing this new hall call can be selected and the new hall can be allotted to the selected elevator car to be serviced by this elevator car. In the system, this new hall call is allotted preferentially to one of the elevator cars having an already instructed stopping floor within a predetermined floor range covering a plurality of backward and/or forward floors contiguous to the new hall call originating floor. In this elevator control system, the already instructed stopping floor is evaluated by employing a weight coefficient which is variable depending on the factor such as the position of the already instructed stopping floor either backward or forward relative to the new hall call originating floor, or the relative distance between such floor and the new hall call originating floor, so as to provide improved elevator service.
Abstract:
In an elevator system comprising a plurality of elevator cars serving a plurality of floors in response to hall calls and cage calls, an elevator control apparatus is provided which comprises a device for forecasting cage calls as a new type of traffic information expected to be registered as hall waiting passengers take a given car. The device includes means arranged on each hall for detecting the number of prospective passengers waiting on the particular hall and means for setting the ratios of the hall waiting passengers destined for respective floors. The detected number of hall waiting passengers is multiplied by the ratios of destination floors (hereinafter referred to as "destination ratios") to figure out floors to which the hall waiting passengers joining the car are most likely to proceed, thus forecasting a corresponding cage call or calls. This cage call forecasting device is used in an elevator control system assigning hall calls, so that a cage call expected to be registered by the serving of a hall call is forecast at an early time. The waiting time required until each car reaches each floor, for example, is thus forecast with high accuracy taking into consideration cage calls expected to be registered in the future.
