  • the group size can be one predetermined number of floors to which one address any specific elevator group properly can. Assume the group size is on five floors then each down-peak traffic group can only respond to three hall calls per cycle.
  • the group size can be determined by looking at the number be determined by cabins that respond to the Downward peak traffic and the number of floors in the Buildings can be allocated. Take for example indicate that the present invention in a fifteen-story Building is used and that the system to respond to Downward peak traffic then used three elevator cars the group size can be divided by dividing the total number of Floors through the assignable elevator cabins determine. In this particular example, the Group size five. So the largest group is that can be allocated to a single elevator car, one Group with five floors.
  • the Step 202 a floor separation (response area) value First specification of floor separation (or area) between the first and last assignable to each group Call initialized.
  • the Floor separation value initially specified as "1" is the Range of calls between the first and last assigned call "1" floor or two neighboring Floors.
  • the range of values of calls for the elevator group a top floor with down hall calls and a number of floors below the first call corridor equal to the specific one Floor separation value included. So if the Floor separation value, for example, initiated as "1" each group is no larger than two neighboring ones Floors. If, for example, a highest floor / hall call comes from floor E10, then that is the first group of assignable range of calls Floors E10 and E9. All floor / hall calls that have their origin under floor E9, one group created below.
  • Down floor / hall calls can be queried.
  • this scanning by a Scanning device 10 are performed, which the in chronological order in the floor / hall call memory RAM1 samples entered values.
  • the samples can then be stored in an allocation memory 11.
  • the Allocation memory 11 contains a "snapshot" of the sampled storey / corridor call memory RAM1. So shows the allocation memory 11 indicates whether from a particular one Floor a down call has been issued and which Floors downward peak traffic allocation by the Require optimization system for downward peak traffic.
  • FIG. 3 provides an example of the floor / hall call memory RAM1 where the calls are in chronological order are saved.
  • Figure 4 shows an example of the Allocation memory 11 after scanning the floor / hall call memory RAM1 by scanner 10.
  • the allocation memory 11 shows by a logical "1" at which floors pending down calls and / or which floors the address by an assignable down-peak traffic elevator cabin require.
  • the Allocation memory 11 simply indicate which floors have requested downward operation, i.e. Floors E15, E14, E13, E11, E10, E9 and E7.
  • the system can count the number of Groups starting with, for example, the top one Floor / hall call floor E15 to determine the To start grouping.
  • Figure 5 shows an example of a first grouping by the optimization system for Down peak traffic.
  • Group g1 can initially call from top down hall call, e.g.
  • group g1 may initially be E15 and E14 included.
  • the group g2 can be the next in Floor / hall call memory stored down floor / hall call included that is not in group g1 is included, e.g. E13.
  • Group g2 can only E13 included as the only other floor that is for inclusion to group g2 as determined by the initial Floor separation value of "1" is available, only E12 would include.
  • Group g3 can the next stored floor / corridor call, e.g. E11 and also E10, contain.
  • Group g4 can contain E9.
  • the group g5 can contain E7.
  • each group has at least one Floor / corridor call must contain. It should also be noted that it is not necessary that every floor in the Grouping scheme is included. The grouping should but does not contain overlapping group members, i.e. each group is not formed overlapping.
  • step 205 After the groups have been created for the first time in step 205 the number of specified groups with the total number of available to service the downward peak traffic load Elevator cabins are compared. Suppose the system is with three to service the downward peak traffic load available elevator cabins, then the three Elevators five in the initial grouping of the down hall calls formed groups not in an adequate way work off.
  • step 207 If the system initially had a number of groups specifies which is greater than the total number to be used of the groups available elevator cabins, then that can Optimization system for downward peak traffic in step 207 increase the floor separation value by a value of "+1", so that the floor separation value can now be "2". So For example, each group can now have three neighboring groups Floors included.
  • the flow chart returns to step 204 back to groups according to the new floor separation or to form the new response value range. So it shows Figure 6 shows an example of after increasing the response range by the optimization system according to the invention for the Downward peak traffic grouping.
  • step 205 the optimization system for the Downward peak traffic count that three groups are formed have been.
  • step 206 the system can now determine whether the number of designated groups is equal to that Number of available elevator cabins is. So the system can in step 208 the floor locations now correspond to the corresponding ones Allocate elevator cabins to reduce the downward traffic load serve.
  • step 202 After assignment of the elevator cabins to respond that can affect the downward peak traffic needs Optimization system for downward peak traffic to step 202 return to the floor separation or the Initialize response range to "1" and steps 203 - Repeat 208.
  • the building once queried and a "snapshot" of the present pending downstairs floor / hall calls are saved and used for the steps grouping-increasing-grouping.
  • the "snapshot" deleted and the system repeats itself from the Initialization of the response area.
  • the system when the number of educated Groups smaller than the number of available for allocation Cabins is the cab with the most advantageous response path the corresponding one-time groups of down calls will allocate.
  • An additional advantage of the present invention is that the present system in Elevator zone systems, i.e. where specified cabins Zones or floors of a building are assigned, can be used. So can the routine discussed above optionally in each predefined building zone zone-wise optimization of downward peak traffic is used become.
