Abstract

According to an embodiment, a method to communicate with a passenger in a car within a transportation system includes receiving an alarm signal from the car, receiving at least one operation parameter from the car, analyzing the at least one operation parameter corresponding to the alarm signal from the car, determining an alarm condition in response to the at least one operation parameter and the alarm signal, and initiating a video session via a video system in response to the alarm signal.

First claim

What is claimed is:

1. A method to communicate with a passenger in a car within a transportation system, the method comprising:
receiving an alarm signal from the car;
receiving at least one operation parameter from the car;
analyzing the at least one operation parameter corresponding to the alarm signal from the car;
determining an alarm condition in response to the at least one operation parameter and the alarm signal; and
initiating a video session via a video system in response to the alarm signal;
wherein determining the alarm condition comprises determining a true alarm condition or a false alarm condition in response to the at least one operation parameter and the alarm signal.

2. The method of claim 1 , wherein the car is an elevator car.

3. The method of claim 1 , further comprising:
initiating the video session via the video system with a dispatch center in response to the false alarm condition.

4. The method of claim 1 , further comprising:
initiating the video session via the video system with a dispatch center in response to the true alarm condition.

5. The method of claim 4 , further comprising:
initiating a communication session with a technician device via the dispatch center.

6. The method of claim 4 , further comprising:
providing the dispatch center with the at least one operation parameter from the car via a control system.

7. The method of claim 4 , further comprising:
providing a control signal from the dispatch center to the car.

8. The method of claim 1 , further comprising:
displaying a video via the video system in response to the false alarm condition.

9. The method of claim 1 , further comprising:
initiating the alarm signal in response to a trapped passenger condition.

10. A system for communication with a passenger within a transportation system, the system comprising:
a car of the transportation system to provide an alarm signal, wherein the car includes a video system;
a control system to provide at least one operation parameter corresponding to the car; and
an alarm response controller to analyze the at least one operation parameter corresponding to the alarm signal and to selectively determine an alarm condition, wherein the alarm response controller initiates a video session via the video system in response to the alarm signal;
wherein the alarm response controller determines a true alarm condition or a false alarm condition for the alarm condition.

11. The system of claim 10 , wherein the car is an elevator car.

12. The system of claim 10 , wherein the alarm response controller initiates the video session via the video system with a dispatch center in response to the false alarm condition.

13. The system of claim 10 , wherein the alarm response controller initiates a video session with a dispatch center in response to the true alarm condition.

14. The system of claim 13 , wherein the alarm response controller initiates a communication session with a technician device and the dispatch center.

15. The system of claim 13 , wherein the dispatch center receives at least one operation parameter from the control system.

16. The system of claim 13 , wherein the dispatch center provides a control signal to the car.

17. The system of claim 10 , wherein the video system includes a video camera and a video screen.

18. The system of claim 10 , wherein the car includes a control panel to selectively provide the alarm signal.
