Abstract

A method for dynamic elevator door control is provided. The method is implemented by a system, which includes an elevator. The system procures passenger data, which can include a number of passengers presently travelling to a floor and a number of passengers awaiting to board at the floor. A determination is made by the system with respect a door operational time based on the passenger data. The system implements the door operational time to dynamically cause doors providing access to the elevator to remain open for a duration of the door operational time.

First claim

What is claimed is:

1. A method for dynamic elevator door control implemented by a system comprising at least one elevator, the method comprising:
procuring, by the system, passenger data comprising a number of passengers presently travelling to a floor and a number of passengers awaiting to board at the floor, wherein the passenger data includes an average user travel speed based on a passenger health profile;
determining, by the system, a door operational time based on the passenger data; and
implementing, by the system, the door operational time to dynamically cause doors providing access to the at least one elevator to remain open for a duration of the door operational time;
wherein the system monitors an access progress of the at least one elevator for the duration of the door operational time to determine whether to dynamically increase the door operational time.

2. The method of claim 1 , wherein the door operational time is summation of one or more individual time intervals corresponding to a total passenger number based on the number of passengers presently travelling to the floor and the number of passengers awaiting to board at the floor.

3. The method of claim 2 , wherein the one or more individual time interval comprises a default time interval for a common passenger and an increased time interval for an elderly passenger.

4. The method of claim 3 , wherein the default time value is two seconds.

5. The method of claim 1 , wherein the system automatically receives one or more elevator calls from one or more mobile devices including source and destination information, the system being in communication with the one or more mobile devices via a network.

6. The method of claim 5 , wherein the passenger data is derived from health profile information of the one or more users based on the one or more elevator calls.

7. The method of claim 1 , wherein the system determines whether any special accommodations are required for the passengers presently travelling to the floor and the passengers awaiting to board at the floor.

8. The method of claim 7 , wherein the special accommodation are determined by at least one sensor utilizing image recognition technology that detects a mobility aid.

9. The method of claim 1 , wherein the system detects the number of passengers awaiting to board at the floor based on a sensor detects one or more users in a lobby of the floor.

10. A system for dynamic elevator door control, the system comprising at least one elevator, the system being configured to:
procure passenger data comprising a number of passengers presently travelling to a floor and a number of passengers awaiting to board at the floor, wherein the passenger data includes an average user travel speed based on a passenger health profile;
determine a door operational time based on the passenger data; and
implement the door operational time to dynamically cause doors providing access to the at least one elevator to remain open for a duration of the door operational time;
wherein the system monitors an access progress of the at least one elevator for the duration of the door operational time to determine whether to dynamically increase the door operational time.

11. The system of claim 10 , wherein the door operational time is summation of one or more individual time intervals corresponding to a total passenger number based on the number of passengers presently travelling to the floor and the number of passengers awaiting to board at the floor.

12. The system of claim 11 , wherein the one or more individual time interval comprises a default time interval for a common passenger and an increased time interval for an elderly passenger.

13. The system of claim 12 , wherein the default time value is two seconds.

14. The system of claim 10 , wherein the system automatically receives one or more elevator calls from one or more mobile devices including source and destination information, the system being in communication with the one or more mobile devices via a network.

15. The system of claim 14 , wherein the passenger data is derived from health profile information of the one or more users based on the one or more elevator calls.

16. The system of claim 10 , wherein the system determines whether any special accommodations are required for the passengers presently travelling to the floor and the passengers awaiting to board at the floor.

17. The system of claim 16 , wherein the special accommodation are determined by at least one sensor utilizing image recognition technology that detects a mobility aid.

18. The system of claim 10 , wherein the system detects the number of passengers awaiting to board at the floor based on a sensor detects one or more users in a lobby of the floor.
