Abstract:
In a group-management control apparatus for an elevator system with plural elevators capable of serving plural floors, hall calls are allotted to adaptive elevators in accordance with a predetermined hall call allotment algorithm, for the purpose of achieving desired control targets. Plural kinds of the hall call allotment algorithm with different schemes are provided in advance, and the predetermined hall call allotment algorithm is selected therefrom by a reasoning operation, which is executed in accordance with a reasoning rule selected from among a plurality of reasoning rules empirically provided in advance on the basis of the desired control targets and an operating state of the elevators.
Abstract:
An elevator system, and method of operating same, having a plurality of elevator cars for serving hall calls registered from the floors of a building. All of the up and down service directions from the floors are continuously assigned to the elevator cars, whether or not they have an active registered hall call associated therewith, with the assignments being made according to predetermined averages which uniformly spread the actual and prospective work loads among the elevator cars. The hall calls are timed. A timed-out call, i.e., a call registered for a predetermined period of time, is given preferential treatment, without significantly disturbing service to other registered hall calls, by assigning the floor and service direction associated with the timed-out call to an additional car which is not already assigned to a timed-out call. The additional car is selected on the basis of its having the lightest work load schedule of all of the elevator cars conditioned to serve the timed-out call.
Abstract:
An elevator system for a building having a plurality of floors, including supervisory system control for controlling a plurality of elevator cars to answer calls for elevator service from the plurality of floors. The system control assigns unassigned service directions from the plurality of floors to each of the elevator cars, until meeting a predetermined dynamic limiting average. The assignments are made to one car at a time, proceeding to the next when a predetermined limiting average is met. The order in which the cars are selected for assignment is a dynamic order, responsive to the relative work loads of the cars. The assignments are made to each car, starting in a predetermined direction from each car's position, and are terminated a predetermined travel distance from the car, if not terminated sooner due to a limiting dynamic average. A predetermined minimum limiting dynamic average may be set, to control the rate at which idle cars become busy cars when traffic increases.
Abstract:
An elevator system includes a control for controlling an elevator into an idle state and/or for cancelling the idle state. The elevator system is configured to receive data from a control circuit external to the elevator system, and the control is arranged to form a control command for controlling the elevator into an idle state and/or for cancelling the idle state on the basis of data received from a control circuit external to the elevator system.
Abstract:
An elevator system can be operated while recording the energy consumption of at least one energy consumer of the elevator system and at least one traffic situation of the elevator system. At least one energy consumption value is determined for the recorded energy consumption and the recorded traffic situation, and the calculated energy consumption value is output to at least one output means.
Abstract:
An elevator group control apparatus performs operation control of a plurality of elevators by detecting a downward traffic flow ratio of traffic flows departing downward from floors higher than a prescribed main floor in the total traffic flow departing from one floor to another. If the downward traffic flow ratio is not less than a prescribed reference value, a standby mode for downward traffic flow is made effective, in which at least one elevator car is caused to be on standby on a floor higher than the main floor and at least one elevator car is caused to be on standby on the main floor.

Abstract:
An elevator system includes at least one elevator, at least one call input device and a call controller. The call input device transmits a call to the call controller. For a transmitted normal operation signal, at least one elevator car of an assigned elevator is activated to drive to the call input floor by at least one elevator controller of the assigned elevator. In a peak-time mode of the elevator system, at least one main operation signal is transmitted to at least one elevator. For a main operation signal transmitted to an elevator, at least one elevator car of said elevator is activated to drive between at least two main operation floors by at least one elevator controller of said elevator.
Abstract:
When an average wait time is low (23, 24) an elevator car (31-34) is parked (39), unable to answer calls, or if a parameter (45) is low (46), the car is shut-down. If wait time is high, a parked car is assigned the call. If no cars are parked, a shut-down car may be assigned based on RRT. If up running cars can answer the call, the down running cars are excluded.
Abstract:
An elevator control system employing a micro-processor-based group controller (FIG. 2) which communicates with the cars (3, 4) 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 the summation for each car, with respect to each call, a weighted summation 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 based on the perceived intensity of traffic, as measured 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. Exemplary apparatus (FIGS. 1 and 2) and a logic flow diagram (FIG. 3) illustrate a specific manner of assigning calls to cars. Tables set forth exemplary varying bonus and penalty values to be assigned, depending on the ratio of the hall call registration time to the selected average hall call waiting time (Tables 1 and 2) or on their differences (Table 3).
