Definitions
- This invention generally relates to controlling elevator traffic flow. More particularly, this invention relates to grouping floors into sectors and assigning particular cars to each sector.
- Elevator systems often include a plurality of elevator cars that each are capable of serving many floors or all of the floors within a building. In many instances, there are certain times during the day when the flow or volume of traffic on the elevator system is greatly increased compared to others.
- Various techniques have been developed to maximize the performance of the elevator system to improve the handling capacity so that elevator passengers receive prompt service.
- One such technique is shown in United States Patent No. 5,183,981, where groups of floors within the building are grouped into contiguous sectors and particular elevator cars are assigned to each sector. The sectoring concept has been shown to provide significant improvement in handling capacity. In some instances the improvement is on the order of fifty percent.
- Other techniques have been developed to reduce the number of stops of an elevator car to improve handling capacity.
- this invention provides various approaches for grouping floors into sectors to enhance the handling capacity of an elevator system.
- SUMMARY OF THE INVENTION In general terms, this invention is an elevator system handling capacity enhancement.
- This invention includes grouping floors into sectors that include at least one sector having at least one floor that is not contiguous with at least one other floor in that sector.
- a system designed according to this invention includes a plurality of elevator cars, each capable of servicing a plurality of floors.
- a controller groups the floors into sectors with at least one sector having at least one floor not contiguous with at least one other floor in that sector. At least one of the cars is assigned to each one of the sectors.
- Figure 1 schematically illustrates an elevator system incorporating a sector arrangement designed according to an example embodiment of this invention.
- Figure 2 schematically illustrates an elevator system incorporating a sector arrangement designed according to another example embodiment of this invention.
- Figure 3 schematically illustrates an elevator system incorporating a sector arrangement designed according to another example embodiment of this invention.
- Figure 4 schematically illustrates an elevator system incorporating a sector arrangement designed according to another example embodiment of this invention.
- FIG. 1 schematically illustrates an elevator system 20 where a plurality of elevator cars 22, 24, 26, 28 and 30 are capable of servicing a plurality of floors within a building.
- the elevator cars are shown at a lobby level L.
- the floors that are serviced by the cars are labeled 2-17 in the drawing.
- the floor numbers are for illustration purposes and do not necessarily correspond to actual building level numbers.
- this invention is not limited to any particular number of elevator cars or floors within a building. Those skilled in the art who have the benefit of this description will realize that the example illustration is one of many arrangements that can incorporate the techniques of this invention.
- Each elevator car is moved through a hoistway by a machine (not illustrated) that is controlled by a controller.
- the elevator car 22 is controlled by a controller 32.
- the cars 24, 26, 28 and 30 have controllers 34, 36, 38 and 40, respectively, associated with them.
- the individual car controllers operate in a known manner to cause desired movement of the cars within the building to service landings responsive to requests made by passengers using hall call buttons or buttons on a car operating panel, for example.
- the illustrated system also includes a main controller 42 that communicates with each of the individual car controllers 32-40.
- the main controller 42 determines information regarding traffic flow patterns for selectively assigning individual ones of the cars 22-30 to particular groupings or sectors of floors within the building to achieve enhanced system capacity.
- FIG. 1 illustrates one example sectoring arrangement designed according to this invention.
- each sector includes four floors within the building.
- the car 24 is assigned to a first sector Si, which in this example includes floors 14, 15, 16 and 17.
- the car 26 is assigned to a second sector S 2 , which includes the floors 10, 11, 12 and 13.
- first and second sectors were the only sectors within the building, they could be considered contiguous sectors. In this example there are two more sectors, which make the overall sectoring arrangement non-contiguous.
- a third sector S 3 which includes floors 5, 7, 8 and 9, is serviced by the car 28.
- a fourth sector S 4 is serviced by the car 30.
- the fourth sector includes floors 2, 3, 4 and 6.
- floors 5 and 6 are not contiguous with other floors within their respective sectors. Accordingly, the overall grouping of floors into sectors is non-contiguous.
- One example technique of arranging the sectors as shown in the illustration of Figure 1 includes initially arranging the floors into preliminary, contiguous sectors and then changing one floor from one sector with one floor from another sector.
- the example of Figure 2 still presents a significant improvement of the handling capacity compared to systems where no sectoring is applied.
- the interchange of floors between sectors does not include all possible two-floor interchanges between otherwise contiguous configurations.
- the non-contiguous configurations include N interchanges applied to a preliminary, contiguous configuration, where N is the smallest integer greater than or equal to half the average sector size over all sectors in a building where the size of the sector is the number of floors.
- N is the smallest integer greater than or equal to half the average sector size over all sectors in a building where the size of the sector is the number of floors.
- a nearly contiguous arrangement would be any sector grouping that is no more than the smallest integer greater than or equal to F/2 away from a contiguous sector grouping.
- the second sector S includes the next available three top floors and the floor beneath the fourth floor (i.e., floor 4 in the illustration). Similarly, the third and fourth sectors are assigned in order.
- all even numbered floors would be considered one sector and all odd numbered floors would be grouped into a second sector.
- one car could be assigned to the even numbered floors from a fixed beginning floor to a selected ending floor for a sector.
- Another car could be assigned to the odd numbered floors between the same beginning and ending floors.
- the building is originally divided into two preliminary, contiguous sectors.
- Floors 2-9 are one preliminary sector and floors 10- 17 are another preliminary sector.
- Each of the preliminary sectors are then subdivided into sectors.
- the two preliminary sectors are divided by two so that four sectors S 1 -S 4 result.
- the car 22 is assigned to the first sector Si, which includes floors 17, 15, 13 and 11.
- the car 30 is assigned to the fourth sector S , which includes floors 8, 6, 4 and 2.
- K and M equal two.
- the K-modulous grouping technique assigns cars to cover floors that are evenly spaced from each other (i.e., every K* floor between a selected starting floor and a selected ending floor). This technique can be described using the following notation. Assume an example where a building has C elevator cars and f floors. The floors are originally grouped into preliminary, contiguous sectors of contiguous floors where the J th contiguous sector begins at floor (start)j and ends at floor (end) j .
- C 2 handles calls to and from floors 11, 14, 17, 20, 23 and 26.
- the car C 3 handles calls to and from floors 12, 15, 18, 21, 24 and 27.
- the car C 5 handles the same floors as car C and car C 6 handles the same floors as C 3 .
- the cars are assigned or labeled in a dynamic fashion such that, for example, the car 24 in Figure 4 is not always car Q.
- Each sector for a car is effectively based upon equally spaced floors within a preliminary, contiguous sector.
- the preceding description is exemplary rather than limiting in nature.
