Abstract

Claims (61)

1. A method for alert generation and handling in a railroad infrastructure, comprising:

receiving, via a second node having a second processor, sensor data related to a railroad asset;

generating an alert if the sensor data satisfies an alert threshold;

determining at least one configured connection type;

defining the second node as a first node type if a first connection type is not configured on the second node;

defining the second node as a second node type if the first connection type is configured on the second node;

transmitting the alert to a third node if a first node is the first node type; and

transmitting the alert to the first node if the second node is the second node type.

2. The method of claim 1 , further comprising the first node:

receiving the alert;

generating an acknowledgment;

transmitting the acknowledgment to at least the second node;

generating a request; and

transmitting the request.

3. The method of claim 2 , further comprising the first node:

determining if the request is acknowledged;

retransmitting the request if the request is not acknowledged; and

terminating the request if the request is acknowledged.

4. The method of claim 1 , wherein the second node is located proximate a railroad track.

5. The method of claim 1 , wherein the second node is located at a crossing house.

6. The method of claim 1 , wherein the railroad asset is a railroad crossing.

7. The method of claim 1 , wherein the second node transmits the alert to the third node via a LoRa protocol.

8. The method of claim 1 , wherein the third node is of the second node type.

9. A method of integrating a node into a railroad monitoring infrastructure, the system comprising:

receiving, via an infrastructure node having a first processor, a first packet having first data;

determining whether on-node processing is required and at least one configured connection type;

defining the infrastructure node as a first node type if a first connection type is not configured on the infrastructure node;

defining the infrastructure node as a second node type if the infrastructure node is configured with the first connection type;

repeating the first packet via a second connection type if the infrastructure node is defined as the first node type; and

processing the first packet to generate a second packet having second data if the infrastructure node is defined as the second node type.

10. The method of claim 9 , further comprising the infrastructure node transmitting the second packet via the first connection type if the infrastructure node is defined as the second node type and the first connection type is available.

11. The method of claim 9 , further comprising the infrastructure node transmitting the second packet via a third connection type if the at least one infrastructure node is of the second node type and the first connection type is not available.

12. The method of claim 9 , further comprising the infrastructure node:

determining, using the first packet, if acknowledgment is required;

requesting acknowledgment if acknowledgment is required; and

terminating transmission of the first or second packet if acknowledgment is received.

13. The method of claim 12 , further comprising the server node generating a first request and transmitting the first request if the second data includes an alert.

14. The method of claim 9 , further comprising:

receiving, via a server node having a second processor, the second packet;

identifying, via a server node, the second data;

generating, via a server node, an acknowledgment if the second data requires acknowledgment; and

transmitting, via a server node, the acknowledgment to the infrastructure node.

15. The method of claim 14 , further comprising the server node:

determining if the second data includes a node status;

generating a second request if the node status indicates that node attention is required; and

transmitting the second request.

16. The method of claim 9 , further comprising the infrastructure node:

determining if the first data has reached a first destination;

if the first destination has been reached, processing the first packet, determining if acknowledgment is required, and, if acknowledgment is required, transmitting an acknowledgment.

17. The method of claim 9 , wherein the infrastructure node includes a first memory having a plurality of data, thresholds, and specifications related to railroad assets.

18. A method of integrating a node into a railroad monitoring infrastructure, the system comprising:

determining, via a first node having a first processor, if a temporal threshold has been satisfied;

determining a node status of the first node after the temporal threshold has been satisfied;

encapsulating processed packet data and retransmitting an encapsulated data packet;

determining one or more connection types for the first node;

defining the first node as a first node type if the first node is not configured with a first connection type;

transmitting the node status to an infrastructure node.

19. The method of claim 9 , wherein the node status includes node connections, health, temperature, and location.

20. The method of claim 9 , further comprising:

defining the first node as a second node type if the first node is configured with a first connection type; and

transmitting the node status to a server node.
