  • Publication number: 20100025161
    Abstract: During elevator modernization, a cross-dispatching system receives hall calls and assigns each hall call to either a group of existing elevator car controllers or a group of new elevator car controllers. The cross-dispatching system creates an inter group relative system response (iRSR) value for the hall call for both the existing group of elevators and the new group of elevators, based upon information from each group such as car location, in-service status, load, and direction. If the group assigned the hall call does not answer the call within a redispatch time period, the cross-dispatching system again calculates the iRSR for each group and reassigns the hall call.

    Abstract: An elevator apparatus is equipped with an elevator component that is operated during operation of an elevator, a detector for measuring a change in a physical quantity other than temperature as to the elevator component, and a control device for controlling the operation of the elevator based on information from the detector. The elevator component is, for example, a hoisting machine for moving a car of the elevator. The hoisting machine has a motor, and a driving sheave that is rotated by the motor. The detector measures a strain of a frame of the motor as the physical quantity other than temperature. The control device determines based on the strain of the frame of the motor whether or not there is an abnormality in the operation of the elevator, and controls the operation of the elevator. It is therefore possible to determine easily and more reliably whether or not there is an abnormality in the operation of the elevator, without the need to directly measure the temperature of the motor (6).

    Abstract: An elevator control system to govern elevator movement to avoid or minimize passenger discomfort caused by pressure changes associated with an elevator's movement and to optimize elevator operation. In one exemplary embodiment, the system uses the passenger's natural relief which occurs while the elevator car is stopped to reduce the pressure difference experienced by the passengers' ears as a factor to optimally control the operation of the elevator. In another example, the system obtains input regarding the traveling speed and conditions of the elevator system. This system then simulates individual trips for passengers that includes monitoring the pressure changes being experienced by passengers throughout the elevator's travels in order to ensure that the pressure differential level for each passenger remains below a designated maximum comfortable and safe level. This system uses the parameters of a successful simulation to govern the actual operation of the elevators.

  • Patent number: 7546906
    Abstract: The present invention discloses an extension to a prior-art genetic algorithm, with which the routing of elevators based on the calls given in an elevator system is formed. A new type of gene, a so-called run type gene, is connected to the chromosome of the genetic algorithm according to the invention, with which gene the desired speed profile for the elevator trip can be set. In this way e.g. an upper limit can be set for the acceleration or for the maximum travel speed of the elevator. By means of the run type gene a kinetic energy term is included in the optimization. The energy consumed by the system can thus be minimized more effectively by means of the algorithm, because the varying travel speeds of the elevators create more freedom of choice for the chromosomes of the algorithm.

  • Patent number: 7484597
    Abstract: A method schedules cars of an elevator system. Each possible assignment of a set of hall calls to a set of cars is represented by a solution vector maintained as a node in a search tree. Each solution vector is evaluated using an ESA-DP process according to an immediate policy to determine initially a best solution. A branch-and-bound process is applied to each solution vector using the initial best solution and the search tree to determine a globally optimal solution for scheduling the cars according to a reassignment policy.

  • Patent number: 7482771
    Abstract: In a method for monitoring a stationary condition of a drive device, a monitoring device provides the drive device with a temporally varying monitoring signal which, when a sensor device connected to the drive device functions properly, modulates a sensor output signal of the sensor device in accordance with the monitoring input signal. The monitoring device receives the sensor signal and monitors it for the presence of a corresponding signal component. In the absence of such a signal component, the monitoring device controls a safety device which converts the drive device into a safe state. When the drive device is controlled by means of at least two phase-shifted current regulators, it is possible for the monitoring device to monitor an output signal of at least one of the current regulators for constancy and to control the safety device when the output signal of the at least one current regulator changes.

  • Patent number: 7475757
    Abstract: A perceived waiting time for a hall call to be answered by a car is determined as a constant times the square (46) of the summation (45) of remaining response time (39) and the amount of time that has expired since the call was registered (38). The time that may be perceived by a passenger to travel to the passenger's destination is determined as a constant times the square (51) of the distance between an estimated destination floor and the floor of the call and a constant times an estimated number of new hall stops and committed hall stops that each car will make (47). Perceived service time is (52) the sum of perceived wait time and perceived travel time. Constants are adjusted so that a long waiting time will yield a quick travel time. Assignment of calls to cars (60) is in accordance (61) with the smallest summation of square (59) of perceived service times for all waiting up calls and down calls.

  • Publication number: 20080302609
    Abstract: The present invention discloses a method, a system and a computer program for the effective evacuation of a building in an emergency, in which at least one elevator can be used as an evacuation aid. In the method the group control of the elevators monitors the numbers of people on the different floors of the building. The floor on which it is assumed are most people is set at each moment of monitoring for a greater priority in an evacuation situation. Taking into account the limited supply power a free elevator car is directed to the floor of the greatest priority, at which the elevator is filled. The full elevator is directed without stopping to the exit floor of the building. The system monitors by means of detectors the safety of the different parts of the building and directs people if necessary to a safe evacuation location to wait for an elevator. A so-called Traffic Forecaster can be used as an aid in defining the priorities.

  • Publication number: 20080277204
    Abstract: A method is provided for controlling a vehicle lifting device, having at least two, preferably moveable, lifting columns (1-4), which are controlled wirelessly. When a switch is activated for raising or lowering the lifting device, a corresponding signal is transmitted wirelessly to the lifting columns (1-4) and additional signals, which are representative of the individual lifting movements, are transmitted to a control device (5). In the case of unacceptably high movement differences between individual lifting columns, the normal operation is stopped. Here, it is essential that for monitoring the wireless signal transmission, the control device (5) exchanges control signals with the lifting columns (1-4) continuously, and the reception of these control signals is monitored at least in one direction.

  • Patent number: 7434665
    Abstract: In down peak, floors of the building are divided into sectors (38), empty cars (50) are assigned (63, 64) to the sector and assigned (65) the highest down call in the sector provided the highest down call is above the committable floor of any car already assigned in the sector, or there is no car assigned in the sector. If a car is not full (52), it will be assigned additional calls (56). If there are no calls in the sector below a car sector which is not full, a long calls routine (67) determines if there is a down call (75), that is in danger of becoming a long-waiting call, ahead of a car (69) and if so, assigns that call to the car (76).

  • Patent number: 7426982
    Abstract: An elevator group control system is provided which stably keeps cage's position in temporally equal interval condition over a long period of time. The present invention provides a system comprising: reference route generating means, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and assignment means which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Since reference routes which guides the cage's trajectory into temporally equal interval condition are generated and car assignment is executed so as to make the respective cages follow their reference routes, it is possible to allow the cages to settle in temporally equal interval condition over a long period of time.
