Abstract

A monitoring system for a train is provided. The monitoring system includes an image capturing device configured to capture a video feed of a designated area associated with the train. The monitoring system also includes a controller coupled to the image capturing device. The controller is configured to receive the video feed from the image capturing device. The controller is configured to analyze the video feed to determine if a predefined triggering event has occurred. The controller is configured to record and store a predefined length of the video feed based on the determination. The controller is configured to provide a notification of the recorded video feed to a user through a user interface. The controller is configured to allow the user to access at least a portion of the recorded video feed through the notification.

Claims

1. A monitoring system for a train, the monitoring system comprising:

an image capturing device configured to capture a video feed of a designated area associated with the train; and

a controller coupled to the image capturing device, the controller configured to;

receive the video feed from the image capturing device;

analyze the video feed to determine if a predefined triggering event has occurred;

record and store a predefined length of the video feed based on the determination;

provide a notification of the recorded video feed to a user through a user interface; and

allow the user to access at least a portion of the recorded video feed through the notification.

2. The monitoring system of claim 1, wherein the controller is coupled to a display unit such that the user interface is provided on the display unit.

3. The monitoring system of claim 1, wherein the controller is further configured to store a timestamp of a start of the triggering event based on the determination.

4. The monitoring system of claim 1, wherein the controller is further coupled to an electronic control module of the train for determination of the occurrence of the triggering event.

5. The monitoring system of claim 1, wherein the length of the video feed is predefined, such that the monitoring system records the video feed for a predefined time period before each of a start and an end of the triggering event.

6. The monitoring system of claim 1, wherein the controller is further configured to identifying a type of the triggering event.

7. The monitoring system of claim 6, wherein the type of the triggering event is any one of high, medium or low priority.

8. The monitoring system of claim 7, wherein the controller is configured to any one of:

provide the notification and allow real-time viewing of the recorded video feed based on identification of the high priority type of the triggering event;

or

log and flag the recorded video feed based on identification of the medium or low priority type of the triggering event.

9. The monitoring system of claim 1, wherein the notification includes any one of:

a set of images, a thumbnail, or a URL link associated with the recorded video feed.

10. The monitoring system of claim 1, wherein analyzing the video feed includes performing image analysis on the video feed for detecting if the triggering event has occurred.

11. The monitoring system of claim 1, wherein the image capturing device is provided on the train and is positioned to capture the video feed any one of inside the train or outside the train.

12. The monitoring system of claim 1, wherein the image capturing device is provided on external infrastructure associated with the train.

13. The monitoring system of claim 1, wherein the controller is provided at a location which is any one of on-board the train or at a remote location.

14. A method for monitoring a train, the method comprising:

receiving, by a controller, a video feed of a designated area associated with the train from an image capturing device;

analyzing, by the controller, the video feed to determine if a predefined triggering event has occurred;

recording and storing, by the controller, a predefined length of the video feed based on the determination;

providing, by the controller, a notification of the recorded video feed to a user through a user interface; and

allowing, by the controller, the user to access at least a portion of the recorded video feed through the notification.

15. The method of claim 14 further comprising storing, by the controller, a timestamp of a start of the triggering event based on the determination.

16. The method of claim 14 further comprising identifying, by the controller, a type of the triggering event.

17. The method of claim 16 further comprising any one of:

providing the notification and allowing real-time viewing of the recorded video feed based on identification of a high priority type of the triggering event by the controller;

or

logging and flagging the recorded video feed based on identification of a low or medium priority type of the triggering event by the controller.

18. The method of claim 14, wherein the notification includes any one of:

a set of images, a thumbnail, or a URL link associated with the recorded video feed.

19. The method of claim 14, wherein analyzing the video feed step includes performing image analysis on the video feed for detecting if the triggering event has occurred.

20. A train comprising:

an engine; and

a monitoring system comprising;

an image capturing device configured to capture a video feed of a designated area associated with the train; and

a controller coupled to the image capturing device, the controller configured to;

receive the video feed from the image capturing device;

analyze the video feed to determine if a predefined triggering event has occurred;

record and store a predefined length of the video feed based on the determination;

provide a notification of the recorded video feed to a user through a user interface; and

allow the user to access at least a portion of the recorded video feed through the notification.
