摘要:
An elevator car dispatching system (100) comprises an elevator control module (102) that controls operation of at least one elevator car. A position monitoring mechanism (104) is coupled to a first elevator car among the at least one elevator car. The position monitoring mechanism (104) is configured to output a position signal in response to movement of the first elevator car. The elevator car dispatching system (100) further comprises an electronic dispatch module (106) that is in electrical communication with the elevator control module (102) and the position monitoring mechanism (104). The dispatch module (106) is configured to determine a vertical position of the first elevator car based on the position signal. The dispatch module (106) is further configured to output a dispatch command signal commanding the elevator control module (102) to adjust operation of the first elevator car based on the vertical position.
摘要:
Assignment of elevators to hall calls is performed directly as a function of one or more system performance parameters, all related to passenger waiting time. Said function is calculated as an objective (meaning object or goal) function dependent upon those system performance parameters.

A method includes recording a primary destination dispatch request from a primary passenger at a first floor position via a destination dispatch controller 115, identifying a terminal floor, providing a terminal floor call signal to the elevator control system via an overlay controller 110, moving an assigned elevator car in a travel direction of the terminal floor, recording at least one secondary destination dispatch request from a secondary passenger at a respective at least one secondary floor position via the destination dispatch controller, approximating a position of the assigned elevator car, determining a target floor position via the destination dispatch controller, entering a target floor call corresponding to the target floor position at a calculated time to stop the assigned elevator car at the target floor position, cancelling all pending calls via the elevator control system 102, and entering at least one recorded destination dispatch request to the elevator control system.

The invention relates to a method for handling destination calls in an elevator group comprising several elevators using destination call control, which method comprises an allocation procedure for situations where the calls can't be served by all elevators of the elevator group in one round trip, in which situation "n" open calls and "m" fixed calls are present, which fixed calls are already allocated but not served, in which allocation procedure a genetic algorithm (GA) is used in which the following succession of steps is performed: a) chromosomes comprising genes are formed, in which chromosomes: - n first genes comprise a correlation of each open call and a corresponding elevator, - n second genes comprise a correlation of each open call and the corresponding number of the round trip in which the open call will be served, and - m third genes comprise a correlation of each fixed call and the corresponding number of the round trip in which the fixed call will be served, b) for each chromosome round trips are calculated for each elevator of the elevator group according to collective control, c) the round trips of all elevators calculated in step b) are evaluated according to known optimization criteria, as e.g. passenger riding time, passenger waiting time, energy consumption, minimum number of round trips etc., d) chromosomes which are evaluated in step c) as sufficient are put forward to the forming of a new generation by per se known GA methods, as e.g. cross-breeding, mutation, etc., e) the steps b) to d) are repeated for each chromosome of each new generation of chromosomes until a stop criterion is achieved, f) the calls are served in collective control according to the best chromosome of the last generation, and g) the destinations of each elevator in its travelling direction in the current round trip according to the best chromosome are shown on a at least one common display shortly before its arrival at said landing. The invention solves the elevator dispatching problem under consideration of more than the current round trip of the elevators in the elevator group.
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.
摘要:
An elevator group control device and an elevator group control method can eliminate congestion caused by stoppage, jam or deadlock in a vertical and horizontal movement type elevator system. The vertical and horizontal movement type elevator system controls running of a plurality of cages capable of vertically moving in a plurality of shafts and horizontally moving between the shafts. In the system, path data are stored for each of the cages, target floor data including target floors are produced on the basis of call data obtained correspondingly to the respective cages and platform call data obtained correspondingly to the respective floors, periods of time required for the cages to arrive at the target floor is predicted on the basis of the path data, target floor data, call data and cage data indicative of positions of the respective cages, and predetermined cages are allotted to predetermined platform calls on the basis of the predicted arrival time.
