Abstract

In an elevator having destination buttons provided on halls of a plurality of floors for appointing destination floors requested by waiting passengers, an operating apparatus for controlling operations of the elevator which is capable of tracking movement of waiting passengers that have depressed the destination buttons. Upon detecting that a passenger has gotten into the cage, only the destination call requested by this passenger is automatically registered as a cage call, whereas the destination call of a passenger not having gotten into the cage is cancelled. A destination call requested by a passenger is also cancelled under the condition that this passenger has egressed from the elevator hall.

Claims

1. In an elevator having hall control panels installed in halls of a plurality of floors and having destination buttons, hall call registration means provided on said hall control panels for registering calls corresponding to destination floors requested by waiting passengers, cage call registration means for registering cage calls corresponding to the destination floors, and operation control means responsive to the hall calls and the cage calls for assigning a cage to serve the requested destination floors, an operating apparatus for controlling operation of the elevator comprising measurement means for tracking movement of the waiting passengers and for generating outputs representative thereof, and decision/control means responsive to the outputs of said measurement means for determining the destination floors to be serviced by said cage by the calls requested by the passengers.

2. An operating apparatus for an elevator according to claim 1 wherein, when the outputs of said measurement means indicate that the waiting passengers have gotten into the assigned cage, said decision/control means registers as the cage calls the halls corresponding to the destination floors requested by the waiting passengers.

3. An operating apparatus for an elevator according to claim 1 wherein, when the outputs of said measurement means indicate that one of the waiting passengers has gotten into the assigned cage, said decision/control means registers as the cage call the hall call corresponding to the destination floor requested by the waiting passenger getting on and cancels the hall calls requested by other waiting passengers who have not gotten into the assigned cage.

4. An operating apparatus for an elevator according to claim 1 wherein said measurement means comprises television camera means for generating an image for each of the passengers waiting in the hall, and dynamic displacement measurement means for analyzing the images generated from said television camera means so as to track the movement of the waiting passengers and to detect positions thereof.

5. An operating apparatus for an elevator according to claim 4 wherein said television camera means is installed in a ceiling of the hall so as to generate the images of the waiting passengers from above.

6. An operating apparatus for an elevator according to claim 4 wherein said television camera means provides a darkest spot in each image of a waiting passenger, and said dynamic displacement measurement means detects and tracks the movement of the darkest spots so as to detect the positions of the waiting passengers.

7. An operating apparatus for an elevator according to claim 6 wherein said dynamic displacement measurement means sets a window of predetermined size around each of the darkest spots such that there are not overlapping spots therebetween and that movement of one darkest spot corresponding to the position of a passenger can be tracked without being affected by another dark spot corresponding to the position of another waiting passenger.

8. An operating apparatus for an elevator according to claim 1 wherein said measurement means provides a reference measurement operation starting point at a place where said hall control panels are located.

9. An operating apparatus for an elevator according to claim 1 wherein, when said measurement means has erroneously missed an image of a waiting passenger, an output is produced corresponding to positional data of the waiting passenger immediately before the missing image.

10. A operating apparatus for an elevator according to claim 1 wherein, when the hall calls are registered on said hall control panels, said measurement means is immediately activated to start tracking the movement of the waiting passengers in the hall.

11. An operating apparatus for an elevator according to claim 1 wherein said measurement means tracks the movement of the waiting passengers on an individual basis and said decision/control means determines the destination floors to be serviced by individually selecting between registering and cancelling the calls which correspond to the respective waiting passengers.

12. An operating apparatus for an elevator according to claim 1 wherein said decision/control means cancels the hall calls corresponding to the destination floors requested by the waiting passengers when the requested hall calls have already been registered in the assigned cage.

13. In an elevator having hall control panels installed in halls of a plurality of floors and including hall buttons, hall call registration means provided on said hall control panels for registering hall calls corresponding to destination floors requested by waiting passengers, cage call registration means for registering cage calls corresponding to desired destination floors, and operation control means responsive to the hall calls and the cage calls for assigning a cage to serve the requested destination floors, an operating apparatus for controlling operations of the elevator comprising measurement means for tracking movement of the waiting passengers and for generating outputs representative thereof, and decision/control means responsive to the outputs of said measurement means for determining whether or not the waiting passengers have egressed from the elevator hall and for cancelling the registration of the hall calls requested by the waiting passengers under at least a condition that the waiting passengers have egressed from the elevator hall.

14. An operating apparatus for an elevator according to claim 13 wherein the hall buttons of said hall control panels are destination buttons for designating floors to be served.

15. An operating apparatus for an elevator according to claim 13 wherein the hall buttons of said hall control panels include up buttons and down buttons for requesting a cage to move in an up direction and a down direction, respectively.

16. An operating apparatus for an elevator according to claim 15, wherein said hall call registration means registers up calls and down calls in response to the depressions of the up buttons and the down buttons, respectively.

17. An operating apparatus for an elevator according to claim 13 wherein said cage call registration means registers the cage calls corresponding to the desired floors in response to the depressions of destination buttons disposed in the cage.

18. An operating apparatus for an elevator according to claim 14 wherein said measurement means tracks movement of individual passengers waiting in the hall and having depressed the destination buttons.

19. An operating apparatus for an elevator according to claim 15 wherein said measurement means tracks movement of the individual passengers waiting in the hall and having depressed the up buttons and the down buttons.

20. An operating apparatus for an elevator according to claim 16 wherein said decision/control means cancels the registration of the up calls or down calls based on the up buttons or down buttons depressed by the waiting passengers under at least the condition that the waiting passengers have egressed from the elevator hall.

21. An operating apparatus for an elevator according to claim 13 wherein, upon detecting that the waiting passengers having depressed the hall buttons do not get in the cage, said decision/control means determines whether the waiting passengers have egressed from the elevator hall.
