Abstract:
A device for reducing the energy consumption is used in an elevator installation which can be alternatively brought into an operating mode and a standby mode wherein in the standby mode the elevator installation is separated from a main energy source and connected with an auxiliary energy source, by means of which basic functions of the elevator installation are maintained so as to enable later entry into the operating mode. The device includes a detecting unit in order to detect a use criterion describing the current use status of the elevator installation. Moreover, a power-saving unit with a microprocessor is provided in order to bring the elevator installation from the operating mode to the standby mode in the case of non-fulfillment of the use criterion and fulfillment of standby criteria and to bring it from the standby mode to the operating mode in the case of non-fulfillment of the standby criteria.
Abstract:
An elevator system controller for efficient group supervisory control while avoiding collisions between two elevator cars in service in a single elevator shaft. The elevator system controller includes a risk calculating unit for calculating a risk of a collision between elevator cars in the same shaft when the elevator cars are responding to a new call for service, a car assigning unit for assignment of an elevator car to respond to the new call based on the risk of collision, and an operation control unit for controlling operation of the elevator cars based on the assignment by the car assigning unit. The risk of collision is calculated for each car, and the risk is recalculated based on a possibility of a withdrawal of one of the elevator cars to a position in the shaft where no collision can occur, based on a predicted arrival time of a car at the floor requiring service. Cars that have high risks of collision when the remaining cars in the same shaft cannot be withdrawn in time to a safe spot are removed as candidates for assignment to respond to the new call. An evaluation is carried out using several evaluation indexes, in addition to the risk of collision, to decide which car is to be assigned to respond to the new call. If a determination of a traffic condition indicates low usage of the elevator cars, one car in each shaft is forwarded to a rest position and paused.

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:
According to the present invention, when a parking floor is set as a remote-hall-operating-panel-installed floor, the parking floor can be canceled. As a result of this, during the movement of a passenger from a remote hall operating panel to an elevator hall, it is possible to prevent a car from being on standby at a remote-hall-operating-panel-installed floor. Therefore, because a car to which a remote hall registration has been assigned can effectively use the moving time of the passenger and hence it is possible to improve the operation efficiency of the whole group supervisory control system. Furthermore, it is possible to reduce useless runs and hence to reduce power consumption.
Abstract:
Provided is an elevator group control apparatus which brings distributed standby control into action when the movement of users is heavy in one direction in an unbalanced manner in time zones which account for large proportions of an elevator use condition of a day, for example, in off-hour zones and time zones in which traffic demand is relatively small, thereby improving the waiting time of users, and does not bring distributed standby control into action when there is no unbalanced condition of the movement of the users, whereby it is possible to perform energy savings by reducing power consumption during runs without greatly worsening the waiting time of the users.In an elevator group control apparatus which performs the operation control of a plurality of elevators, there is detected 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. If the above-described standby mode for downward traffic flow has been made effective, 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:
The present invention discloses a method for optimal routing of the elevators in an elevator system in a situation where the supply power received by the system is limited e.g. due to emergency power operation. In the invention, routes are optimized by using a cost function to which has been added a term containing the summed instantaneous power consumed. Power consumption is monitored in real time, and the elevators need a start permission from the control system. A route alternative that exceeds the power limit is penalized in the cost function by a so-called penal term. With the elevator routing obtained as a result, the instantaneous power consumed by the system remains continuously below the set power limit. Some call can thus be postponed to be served later. By the method of the invention, the number of elevators serving passengers in an emergency power situation can be varied dynamically.
