Abstract

A system including one or more processors, one or more non-transitory storage mediums, a data file, and executable instructions. The processor is configured to receive a door close signal from a door close selector and a door open signal from at least one of a door open selector and a door obstructed sensor. The data file is stored in the non-transitory storage medium and includes a door open time duration associated with at least one of the door open signal and the door close signal. The executable instructions are stored in the non-transitory storage medium and is executed by the processor. The executable instructions are configured to generate the door open time duration based on at least one of the door open signal and the door close signal. The processor is configured to output a door open command based, at least in-part, on the door open time duration.

First claim

What is claimed is:

1. A system comprising:
one or more processors configured to receive a door close signal from a door close selector and a door open signal from at least one of a door open selector and a door obstructed sensor;
one or more non-transitory storage mediums;
a data file stored in the one or more non-transitory storage mediums and including an initial door open time duration; and
executable instructions stored in the one or more non-transitory storage mediums and executed by the one or more processors, the executable instructions configured to generate an adjustment to the initial door open time duration based on a set of door open signals and a set of door close signals;
wherein each door open signal in the set of door open signals represents an attempt by any one of a plurality of occupants to keep one of a plurality of elevator car doors open beyond the initial door dwell time;
wherein each door close signal in the set of door close signals represents an attempt by any one of the plurality of occupants to close one of the plurality of elevator car doors in less than the initial door dwell time; and
wherein the one or more processors are configured to output a door open command based at least in-part on the initial door open time duration and the adjustment to the initial door open time duration.

2. The system set forth in claim 1 , wherein the door close selectors are adapted to open and close the plurality of elevator car doors.

3. The system set forth in claim 2 , wherein the executable instructions are further configured to generate the adjustment to the initial door open time duration based on a plurality locations of the plurality of elevator car doors.

4. The system set forth in claim 3 , wherein the adjustment to the initial door open time duration is one of a plurality of adjustments to the initial door open time durations, and each one of the plurality of adjustments to the initial door open time durations is associated with a respective one of the plurality of locations of the plurality elevator car doors.

5. The system set forth in claim 4 , wherein the plurality of elevator car door locations is a plurality of floors.

6. The system set forth in claim 1 , wherein the adjustment to the initial door open time duration is a function of a time of day stored in the data file.

7. The system set forth in claim 6 , wherein the adjustment to the initial door open time duration is a function of a day in a week stored in the data file.

8. The system set forth in claim 4 , wherein each one of the plurality of adjustment to the initial door open time duration is a function of a time of day stored in the data file.

9. The system set forth in claim 8 , wherein each one of the plurality of adjustments to the initial door open time duration is a function of a day in a week stored in the data file.

10. The system set forth in claim 4 , wherein each one of the plurality of adjustments to the initial door open time duration is a function of elevator car traveling direction.

11. The system set forth in claim 9 , wherein each one of the plurality of adjustments to the initial door open time duration is a function of elevator car traveling direction.

12. The system set forth in claim 1 , wherein the one or more processors and the one or more non-transitory storage mediums are part of a cloud.

13. The system set forth in claim 1 , wherein the executable instructions include machine learning operable to use the set of door open signals and the set of door close signals to determine the adjustment to the initial door open time duration.

14. The system set forth in claim 4 , wherein the executable instructions include machine learning operable to use the set of door open signals and the set of door close signals to determine the plurality of adjustments to the initial door open time duration.
