Abstract:
An administrative controlling apparatus for elevators, for calling an elevator before a passenger's operation of a hall call button when a passenger who has come to an elevator hall is detected by passenger detection devices. The direction in which the passenger would like to go is predicted based upon the hall call and past passengers. Accordingly, the past usage is regarded as a basis for a statistical learning process. On this basis, the selection of a stand-by elevator or the selection of a tentative allocation elevator is effected. Also, a call is interrupted in accordance with the absence or presence of an elevator call.
Abstract:
In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.
Abstract:
The disclosure concerns a group supervisory control system for an elevator having statistical traffic data for the elevator from a past time interval and controlling the operation of the car dependent on the statistical data wherein the system comprises an operating apparatus which detects the distinction points of the variation of the traffic data to output traffic data and time for the distinction points as statistical data.
Abstract:
An elevator group supervisory control system for allocating elevator hall calls to elevator cars depending upon estimates given by processing of data indicative of travels of said cars, including a probability processor for determining an estimated future response probability based on predetermined travel data and an estimation processor for allocating hall calls to respective elevator cars based at least in part on the estimated future response probability.
Abstract:
With this group control the allocation of elevator cabins or cars to existing storey or floor calls should be timewise optimized and newly arriving storey calls should be immediately allocated. A computer device provided for each elevator computates at each landing or storey, irrespective of whether or not there is present a storey or landing call, from the distance between the storey and the cabin position indicated by a selector, the intermediate cabin stops to be expected within this distance and the momentary cabin load a sum proportional to the time losses of waiting passengers. In this way the cabin load prevailing at the computation time point is corrected such that the expected number of passengers entering and exiting the cabin, derived from the previously ascertained number of entering and exiting passengers, is taken into account for the future intermediate cabin stops. Such loss time sum, also referred to as the servicing cost, is stored in a cost storage or memory provided for each elevator and infed to a comparator. During a cost comparison cycle the servicing costs of all elevators are compared with one another, and in an allocation storage of the elevator with the lowest servicing cost there can be stored an allocation instruction which designates that storey or floor to which there can be optimumly allocated the relevant elevator cabin.
Abstract:
An elevator control apparatus is provided with means for detecting a new type of elevator car traffic information consisting of the information indicating, by allotting the passengers in the car to resistered cage calls, how many passengers classified for each of destination floors are in the car, namely, the information indicating the number of in-cage passengers classified for each of destination floors. In an apparatus comprising means for allotting a hall call generated to an optimum one of a plurality of cars and means for detecting the number of prospective passengers waiting on the floors, the number of prospective passengers waiting at the floor the hall call from which is allotted to the car and the number of passengers classified for each of destination floors are added to or subtracted from the number of passengers in the car for each floor involved thereby to forecast the number of in-cage passengers in the leading floors. It is decided whether there is room available or not in the car for accomodating additional passengers at the leading floors, by comparing the forecast number of passengers in the car with a predetermined number limit of the passengers for the car. By the use of the result of this decision, the hall call is prevented from being allotted to a car having no room for accomodating additional passengers.
Abstract:
Elevator cars for servicing a plurality of floors are under the control of register means provided at elevator halls to registrate the hall calls for the up- and down-directions. Detector means are installed at the elevator halls to detect the number of the passengers awaiting the cars at the halls. Discriminator means are employed to obtain the information concerning the number of the car awaiting passengers classified for each of the directions of their destinations. The information thus obtained is utilized in the elevator control apparatus to operate the elevator system with a high working efficiency. When the hall calls for one direction are registrated, the detected number of the car awaiting passengers is regarded as the number of the awaiting passengers for the hall calls of the above one direction. When the hall calls for the two directions are registrated, the detected number of the car awaiting passengers are divided into two classes, one for one direction and the other class for other direction on the basis of an appropriate dividing ratio, to thereby detect the number of the awaiting passengers for each of the directions of their destinations. This information about the number of the passengers for each of the directions is utilized in the elevator control operation for allotting the registrated hall calls to the cars. Adder devices are provided for adding together the number of the car awaiting passengers relevant to the allotted hall calls and the number of the passengers in the car to estimate the number of the passengers to be transported by the car. The information of the estimated number of the passenger is utilized for predicting the possible occurrence of the car-full condition. The allotment of the hall calls to the car for which the no-vacancy condition is predicted is restricted.
Abstract:
In an approach for determining an optimal path for an elevator, a processor receives information, wherein the information includes social media data associated with a user and calendar entries associated with the user, indicating one or more locations within a building. A processor analyzes the received information. A processor determines a location to send an elevator within the building to minimize movement of the elevator, based on the analyzed information. A processor causes the elevator to move to the location.
Abstract:
According to an aspect, there is provided a method and an apparatus for determining an allocation decision for at least one elevator. In the solution existing calls are used in an elevator system as a first input in a machine learning module. The first input is processed with the machine learning module to provide a first output comprising a first allocation decision. The first output is then used as a second input in an iterative module. The second input is processed with the iterative module to provide a second output comprising a second allocation decision. The second allocation decision is provided to an elevator control module and to an allocation decision storage for further machine learning module training.
Abstract:
A method schedules elevator cars in a group elevator system in a building by first generating a set of probability distributions for arrivals of future passengers at any floor of the building, wherein the set of probability distributions are characterized by probabilistic variables that specify arrival information of the future passengers, wherein the arrival information includes a probability of service requests by the future passengers and a probability of possible times of the service requests. A schedule for the elevator cars is based on the set of probabilistic distribution. Then, the schedule is provided to a controller of the group elevator system to move the elevator cars according to the schedule.
