Abstract:
A method of allocating calls of a lift installation with at least one lift and at least one car per lift to move passengers in a journey from at least one input floor to at least one destination floor, a system for executing the method and a computer readable memory with instructions for executing the method. The method includes receiving input calls from passengers travelling from an input floor to a destination floor, each call identifying at least one floor as an input floor or a destination floor. A start zone with identified input floors and a destination zone with identified destination floors are determined from the input calls and destination calls. Each identified floor within a corresponding zone is considered using at least one selection criterion and a stopping floor is selected which satisfies the criterion. The car is caused to stop at fewer than all the identified input floors and identified destination floors during the journey.
Abstract:
A method for allocating destination calls in an elevator system, the system including at least one multi-deck elevator, where the passenger gives his/her destination floor by means of a destination call device at the beginning of the journey route, thereby defining the staffing point and final point of the passenger's journey route in the elevator system. The method includes the steps of generating possible route alternatives from the staffing point to the final point of the journey route, determining a cost function containing at least one travel time term, determining the value of the travel time term corresponding to each route alternative in the cost function, calculating the total cost of each route alternative by using the cost function, allocating for the passenger the route alternative that gives the minimum total cost, and guiding the passenger to a waiting lobby and/or elevator consistent with the route alternative allocated.
Abstract:
One version of this disclosure includes a system for assigning an elevator car to respond to a call signal wherein a controller is responsible for determining which elevator car will respond to a call signal. This version includes the controller receiving a hall call signal, receiving information regarding the elevator system, determining whether the call assignment can be made in view of a first rule associated with a banned call assignment, and eliminating the rule against banned call assignments when necessary to avoid saturation of the elevator system.
Abstract:
An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators. A time-table and target elevator service quality parameters may be selected to control destination elevators according to one or more customer selectable mode of operation parameters. The data structure may be processed to control UP and/or DOWN transportation capacities of the destination elevators while satisfying the one or more customer selectable mode of operation parameters.Some intelligent destination elevator control systems may control when elevator cars of a group service the floors of a building. Control of the elevator cars may be flexible to allow the system to increase or decrease traffic capacities of the elevator cars in accordance with anticipated traffic conditions.
Abstract:
A device for controlling a elevator installation with multiple deck cars which are simultaneously accessible at a main stopping point by different main stopping floors includes a call registering device by which a passenger can input a destination floor. In order to enable a more rapid filling of the building, a conversion unit responds to the destination call travel orders already allocated to and/or demanded of the multiple car having the deck which is to be allocated to the passenger to minimize the number of stops of the car. An indicating device indicates to the passenger the allocated car deck and/or the main stopping floor thereof.
Abstract:
In an elevator system in which two cars operate in each shaft, there is provided an elevator group control apparatus providing efficient services while preventing collisions of cars in each shaft. The elevator group control apparatus includes a traffic detection part which detects data of car traffic generated in a building; a zone setting part which sets a dedicated zone and a common zone for each of upper and lower cars in accordance with detection by the traffic detection part; an assignment decision part which decides a car to be assigned to a call generated at a hall in accordance with the call generation floor, direction of response to the call, and a zone set by the zone setting part; an entry determination part which, when a first of two cars in each shaft is coming into the common zone from its dedicated zone, determines, based on position, direction of movement, and state of the other car in the same shaft, whether the first car in each shaft is permitted to enter the common zone; a passing-by instruction part which gives a passing-by instruction to a prescribed floor in the dedicated zone to make each car exit from the common zone to its dedicated zone after each car has entered the common zone; and an operation control part which controls operation of each car based on a decision by the assignment decision part, a determination by the entry determination part, and an instruction by the passing-by instruction part.
Abstract:
An elevator installation with multiple deck cars serves several floors simultaneously with one stop is controlled such that the travel requests are allocated to the most suitable elevator car of the elevator group and the allocation of a travel request from a starting-point floor to a destination floor to a car deck of the elevator car takes place shortly before reaching the starting-point floor. A travel request can also be redistributed or allocated to another deck at any time up to shortly before reaching the starting-point floor. The allocation of the travel request is carried out in dependence on general criteria and/or in dependence on allocated travel requests for the region of the starting-point floor and/or in dependence on allocated travel requests for the region of the destination floor.
Abstract:
A system and method for controlling an elevator group including several elevators and related call devices which controls each elevator in a manner determined by the calls entered and the existing control instructions. When the control system has to decide between two or more control alternatives, a systematic decision analysis is performed by studying the effects resulting from each alternative decision, the effects resulting from each alternative decision, the effects being estimated by simulating by a Monte-Carlo type method the future behavior of the elevator system in the case of each alternative decision. To carry out the simulation, realizations are generated at random for the unknown quantities associated with the current state of the elevator system and for new external future events, and a control decision is made on the basis of the results of the decision analysis.
