Abstract

According to various aspects, exemplary embodiments are disclosed of systems and methods related to shipment tracking for trains. In an exemplary embodiment, a shipment tracking system generally includes one or more Bluetooth nodes positionable onboard one or more cars of a train. The one or more Bluetooth nodes are configured to transmit shipment information for the one or more cars. A gateway device is configured to receive shipment information for the one or more cars. The gateway device is configured to transmit payload information to a database.

Claims

1. A shipment tracking system for a train having one or more cars, the system comprising:

one or more Bluetooth nodes positionable onboard the one or more cars and configured to transmit shipment information for the one or more cars; and

a gateway device positionable onboard the train and configured to receive shipment information for the one or more cars, the gateway device configured to transmit payload information to a database, the payload information including the shipment information for the one or more cars.

2. The system of claim 1, wherein:

the one or more Bluetooth nodes comprise a plurality of Bluetooth nodes;

the train includes a plurality of cars each including at least one of the plurality of Bluetooth nodes;

each Bluetooth node configured to transmit shipment information for a corresponding car on which it is positioned to another Bluetooth node on another car that is closer to the gateway device; and

the gateway device is configured to receive shipment information for each of the plurality of cars and to transmit payload information including an aggregation of shipment information for each of the plurality of cars of the train to a database.

3. The system of claim 1, wherein:

the train includes an engine having the gateway device; and

the one or more Bluetooth nodes comprise a plurality of Bluetooth nodes each configured to receive shipment information from another Bluetooth node on a car farther from the engine and relay the received shipment information to another Bluetooth node on a car closer to the engine;

whereby the plurality of Bluetooth nodes are cooperatively operable for transmitting shipment information in a forward car-to-car direction along the train to the gateway device.

4. The system of claim 1, wherein:

the train includes a caboose having the gateway device; and

the one or more Bluetooth nodes comprise a plurality of Bluetooth nodes each configured to receive shipment information from another Bluetooth node on a car farther from the caboose and relay the received shipment information to another Bluetooth node on a car closer to the caboose;

whereby the plurality of Bluetooth nodes are cooperatively operable for transmitting shipment information from Bluetooth node to Bluetooth node in a backward car-to-car direction along the train towards the caboose and the gateway device.

5. The system of claim 1, wherein each of the one or more Bluetooth nodes includes a universally unique identifier (UUID) defining shipment information for a corresponding car on which it is positioned.

6. The system of claim 5, wherein the shipment information includes contents, destination, and/or identification of the corresponding car.

7. The system of claim 1, wherein the one or more Bluetooth nodes comprise a Bluetooth beacon and/or a Bluetooth low energy (BLE) beacon.

8. The system of claim 1, wherein the gateway device is configured to transmit the payload information to the database over a global system for mobile communications (GSM) gateway.

9. The system of claim 1, wherein the train includes a satellite navigation receiver configured to determine a location of the train, the gateway device configured to transmit location information for the train to the database.

10. The system of claim 1, wherein:

each of the one or more Bluetooth nodes includes limited power and/or a directed antenna to substantially inhibit each Bluetooth node from communicating with other Bluetooth nodes outside of the train; and

/or

each of the one or more Bluetooth nodes includes a directional antenna configured to generate a polar conical beam to limit Bluetooth communication to direction fore and aft relative to a longitudinal axis of the train.

11. The system of claim 1, wherein each of the one or more Bluetooth nodes is configured to obtain shipment information from contents of a car on which it is positioned by receiving information from one or more tags attached to the contents of the car.

12. The system of claim 1, wherein each of the one or more Bluetooth nodes is configured to communicate with other Bluetooth nodes using a Bluetooth 4.1 protocol.

13. A train comprising a plurality of cars and the system of claim 1, wherein:

each car includes at least one of the one or more Bluetooth nodes;

each Bluetooth node is configured to transmit shipment information for a corresponding car on which it is positioned to another Bluetooth node on another car that is closer to the gateway device;

the gateway device is configured to receive shipment information for each of the plurality of cars; and

the gateway device is configured to transmit payload information to the database, the payload information including an aggregation of shipment information for each of the plurality of cars.

14. A shipment tracking method for a train having one or more cars, the method comprising:

obtaining, via one or more Bluetooth nodes onboard the one or more cars, shipment information for the one or more cars;

relaying, via at least one of the one or more Bluetooth nodes, the shipment information for the one or more cars to a gateway device onboard the train; and

transmitting, via the gateway device, payload information to a database, the payload information including the shipment information for the one or more cars.

15. The method of claim 14, wherein the one or more Bluetooth nodes comprise a plurality of Bluetooth nodes, and wherein the method includes:

obtaining, via the plurality of Bluetooth nodes each located at one of a plurality of cars of a train, shipment information for each of the cars;

relaying, via at least one of the plurality of Bluetooth nodes, the shipment information for each of the cars to the gateway device; and

transmitting, via the gateway device, payload information to the database, the payload information including an aggregation of shipment information for each of the plurality of cars to the database.

16. The method of claim 14, wherein relaying shipment information includes receiving shipment information at a Bluetooth node from another Bluetooth node corresponding to a car farther from the gateway device and then transmitting the received shipment information from the Bluetooth node to another Bluetooth node corresponding to a car closer to the gateway device.

17. The method of claim 14, wherein:

transmitting payload information includes transmitting location information indicating a location of the train; and

/or

the shipment information includes contents, destination, and/or identification of the corresponding car.

18. The method of claim 14, wherein relaying includes directing a Bluetooth signal along a longitudinal axis of the train to inhibit Bluetooth communication with Bluetooth nodes outside of the train.

19. A method of providing a train with a shipment tracking system, the method comprising:

positioning one or more Bluetooth nodes onboard one or more cars of the train, the one or more Bluetooth nodes configured to transmit shipment information for the one or more cars; and

positioning a gateway device onboard the train, the gateway device configured to receive shipment information for the one or more cars, the gateway device configured to transmit payload information to a database, the payload information including the shipment information for the one or more cars.

20. The method of claim 19, wherein:

positioning one or more Bluetooth nodes comprises positioning a Bluetooth node on each of a plurality of cars of the train, each Bluetooth node configured to transmit shipment information for a corresponding car on which it is positioned to another Bluetooth node on another car that is closer to the gateway device; and

the gateway device is configured to receive shipment information for each of the plurality of cars and to transmit payload information including an aggregation of shipment information for each car of the plurality of cars of the train to a database.
