Abstract

An exemplary method includes distributing identifying tags to a plurality of potential elevator passengers so that each passenger has a uniquely identifiable one of the tags. Collective elevator system traffic information is determined based on monitoring movement of individual ones of the plurality of tags and corresponding elevator system operation.

First claim

I claim:

1. A method comprising the steps of:
distributing identifying tags to a plurality of potential elevator passengers such that each passenger has a uniquely identifiable one of the tags, wherein at least some of the identifying tags are associated with each other based on some relationship between the passengers having the associated identifying tags;
monitoring movement of a plurality of the tags; and
determining collective elevator system traffic information based on the monitored movement of individual ones of the plurality of tags and corresponding elevator system operation.

2. The method of claim 1 , comprising monitoring the movement during a survey period, and determining the elevator system traffic after at least a portion of the survey period is complete.

3. The method of claim 2 , comprising compiling information regarding the movement of a plurality of the tags collected during the survey period.

4. The method of claim 1 , wherein the step of monitoring movement includes collecting location information indicative of a location of each of the monitored tags within the elevator system, and associating the location information with collected time information.

5. The method of claim 4 , wherein the location information is gathered by a plurality of detectors in communication with a controller.

6. The method of claim 5 , comprising discriminating between the time and location information for each of the uniquely identifiable tags that are monitored and maintaining anonymity for each passenger corresponding to each monitored tag.

7. The method of claim 5 , wherein the elevator system includes a plurality of elevator cars, and comprising positioning at least one of the detectors that is configured to detect any of the tags in a vicinity of each of the elevator cars, the detectors providing an indication when any of the tags enters or exits a corresponding one of the elevator cars.

8. The method of claim 1 , comprising offering an incentive to each of the plurality of potential passengers to carry one of the tags.

9. The method of claim 1 , wherein distributing step includes anonymously distributing the tags to the plurality of potential elevator passengers to protect the identities of the potential elevator passengers.

10. The method of claim 1 , wherein the tags comprise at least one of radio-frequency identification (RFID) tags and mobile devices configured to exchange data over short distances using short range radio transmissions.

11. An elevator traffic monitoring system, comprising:
a plurality of identifying tags configured to be distributed to a plurality of potential elevator passengers such that each of the elevator passengers has a uniquely identifiable one of the tags wherein at least some of the identifying tags are associated with each other based on some relationship between the passengers having the associated identifying tags; and
a controller configured to determine collective elevator system traffic information based on monitored movement of individual ones of the plurality of tags and corresponding elevator system operation.

12. The system of claim 11 , including a plurality of detectors configured to detect any of the tags, the detectors communicating information to the controller indicating when a detected tag enters or exits an elevator car, the controller being configured to associate the detected tag information with elevator system operation information corresponding to travel of the tags within the elevator system.

13. The system of claim 12 , including a plurality of elevator cars, and wherein each of the elevator cars is associated with at least one of the detectors.

14. The system of claim 12 , wherein the elevator system includes a plurality of the detectors positioned in each hallway where a passenger can access an elevator car of the elevator system.

15. The system of claim 11 , wherein the tags comprise at least one of radio-frequency identification (RFID) tags and mobile devices configured to exchange data over short distances using short range radio transmissions.

16. The system of claim 11 , wherein the relationship comprises being members of a group and the controller determines elevator traffic information of the group.

17. The system of claim 11 , wherein the relationship comprises the passengers having the associated identifying tags being members of at least one of:
a group having a common reason for being in a building,
an organization,
a company, and
a tenant in a building.

18. The system of claim 11 , wherein the controller is configured to determine the collective elevator system traffic information including at least one of:
(i) determining elevator travel of each passenger individually and elevator travel of the passengers having the associated identifying tags collectively,
(ii) distinguishing elevator travel of passengers that are primary occupants of at least one selected floor of a building from elevator travel of other types of passengers, and
(iii) comparing elevator traffic patterns of different groups of passengers.

19. The method of claim 1 , wherein the relationship comprises the passengers having the associated identifying tags being members of at least one of:
a group having a common reason for being in a building,
an organization,
a company, and
a tenant in a building.

20. The method of claim 11 , wherein determining collective elevator system traffic information comprises at least one of:
(i) determining elevator travel of each passenger individually and elevator travel of the passengers having the associated identifying tags collectively,
(ii) distinguishing elevator travel of passengers that are primary occupants of at least one selected floor of a building from elevator travel of other types of passengers, and
(iii) comparing elevator traffic patterns of different groups of passengers.
