摘要:
The present invention provides a method and apparatus for use in elevator systems for assigning new hall calls to one of a plurality of available elevator cars. The method comprises calculating for each car a call cost for accepting the new hall call. The call cost is a function of the estimated time to the desired destination of the passenger requesting the new hall call and of the delay that other passagers who are using the elevator car will experience. In one embodiment, a destination is inferred for the passenger requesting the new hall call. In another embodiment, the passenger requesting the hall call may input a desired destination at the time the hall call request is made. The elevator system of the present invention allows for use of both standard up/down hall call entry devices and destination entry devices that allow a particular destination to be entered by a passenger at the time a hall call is requested.

An elevator group comprising at least two elevator cars (Car1, Car2) is controlled using a group control unit which allocates the calls to different elevators. Based on statistical data and/or statistical forecasts, a virtual passenger traffic is generated and simulation is applied to create events in the virtual passenger traffic, on the basis of which an elevator-specific cost is computed for each call to be allocated. Based on the costs, the best elevator is selected to serve the call.

To assign a car to a hall call such that cars A, B, C, D tend to be equally spaced apart and so that bunching of cars is avoided, the position of each car is predicted over a given period by estimating where it will arrive and leave each of its committed stops over that period for a given set of hall call/car call assignments, a bunching measure is calculated and a car to hall call assignment is made in response to the bunching measure.

An elevator control system employing a micro-processor-based group controller ( Fig. 2 ) which communicates with the cars of the elevator system to determine conditions of the cars and responds to hall calls registered at a plurality of landings in the building serviced by the cars under control of the group controller, to provide assignments of the hall calls to the cars based on a weighted summation for each car, wi h reapect to each call, of a plurality of system response factors, some indicative, and some not, of conditions of the car irrespective of the call to be assigned, assigning "bonuses" and "penalties" to them in the weighted summation. In the invention, rather than a set of unvarying bonuses and penalties being assigned based on the relative system response factors, the assigned bonuses and penalties are varied (4,6) based on the perceived intensity of traffic, as measured (3,5) by, for example, a past average waiting time and the elapsed time since registration of the hall call, a selected past five minute average waiting time being exemplary.

The invention relates to a control system for an elevator system comprising a plurality of elevator cars (11 - 15) and an elevator control for assigning elevator cars to destination calls, wherein the elevator control is adapted, in a first mode of operation, to determine and assign an elevator car (11 - 15), which the passenger shall use, based on at least one elevator car determination criterion, information indicating the elevator car thus assigned not being communicated to the passenger car until or until shortly before the assigned elevator car (11- 15) arrives at the entrance landing.

Provided is a group management system for an elevator which is capable of making a change as necessary even after an assignment car is determined and providing a service comfortable for a user. The group management system is provided with a call registration device for registering a loading zone destination call before a user is loaded on the elevator, a car position detection unit for detecting a car position of the elevator, and a call registration storage unit for storing the registered loading zone destination call for each elevator. In the case where a loading zone destination call, the content of which is the same as the already registered loading zone destination call stored in the call registration storage unit is newly registered by the call registration device, if a non-assignment car has already reached a floor where the call registration device is installed, the loading zone destination call of the new registration is assigned to the non-assignment car.
