Abstract:
According to one embodiment, an elevator group control apparatus performs group control of operations of cars. The apparatus includes a power consumption calculation unit that calculates power consumption when each of the cars is run according to the operation curve on the basis of object data stored in the object data storage unit and an operation curve created by the operation curve creation unit, a distributed waiting controller that sets a car in a waiting state among the cars as a distributed waiting target car and outputs a distributed waiting instruction to move the target car to a distributed waiting floor, and a distribution instruction controller that obtains, from the power consumption calculation unit, power consumption when the distributed waiting target car is moved to the distributed waiting floor and, on the basis of the power consumption, permits or inhibits a distributed waiting instruction output from the distributed waiting controller.
Abstract:
A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain wait time thresholds. The controller receives a hall call signal, and the controller is programmed with wait time thresholds that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT). In this example, these thresholds are time values above which a passenger is likely to become impatient, either waiting for an elevator car to arrive, or waiting for their elevator car to arrive at its destination. Based on system information an EWT and ETT are calculated and compared to the thresholds. An elevator car is assigned based on this comparison. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.
Abstract:
Described is a method for assigning hall calls comprising the steps of receiving a hall call signal, receiving information regarding an elevator system, assigning a destination to the hall call signal, and calculating a call cost value for each elevator car using a handing capacity coefficient. The controller designates the elevator with the lowest call cost value to respond to a call signal. The handling capacity coefficient is a value that reflects the current traffic conditions of an elevator system.
Abstract:
The present invention relates to a method for controlling the elevators of an elevator group in a building divided into zones comprising different floors in such manner that, at the passenger's departure floor, the elevators are given calls to floors beyond the zone limits of the departure zone. According to the invention, the aforesaid call is divided into two or more calls.
Abstract:
A perceived waiting time for a hall call to be answered by a car is determined as a constant times the square (46) of the summation (45) of remaining response time (39) and the amount of time that has expired since the call was registered (38). The time that may be perceived by a passenger to travel to the passenger's destination is determined as a constant times the square (51) of the distance between an estimated destination floor and the floor of the call and a constant times an estimated number of new hall stops and committed hall stops that each car will make (47). Perceived service time is (52) the sum of perceived wait time and perceived travel time. Constants are adjusted so that a long waiting time will yield a quick travel time. Assignment of calls to cars (60) is in accordance (61) with the smallest summation of square (59) of perceived service times for all waiting up calls and down calls.
Abstract:
Energy saving methods and apparatus for elevator systems having a plurality of elevator cars operating in a plurality of elevator shafts. The present invention provides methods and apparatus for determining which one of the plurality of elevator cars is to be assigned to a new hall call in order to reduce the net energy consumption of the elevator system over time.
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.
