Abstract

An asset tracking system that optimizes the value per ping by tying the ping to a pattern of movements of the asset. The asset tracking device will send a ping to a remote host (i.e., receiver) when predetermined qualified event is detected by the device. In such a manner, the value per ping is optimized, leading to increased battery life and decreased operational cost. To satisfy these conditions, the asset tracking device is equipped with appropriate sensors, actuators, and trigger mechanism(s). A four-phase methodology or algorithm used to detect and determine when detected motions and movements warrant triggering the data ping.

Claims

1. A method of tracking an asset, the method comprising:

transmitting, by a transmitter located with the asset, an initial set of data pings at an initial frequency, wherein a data ping includes data relative to the asset;

detecting a series of movements of the asset, wherein detecting includes using a motion sensor coupled to the transmitter;

creating one or more actions, wherein creating includes combining the series of movements;

correlating the one or more actions to a qualified event, wherein the qualified event is predefined by a unique pattern in the one or more actions; and

transmitting, by the transmitter, a subsequent set of data pings at a subsequent frequency, wherein the subsequent set of data pings are transmitted based on the correlation of the one or more actions to the qualified event, and wherein the subsequent frequency is greater than the initial frequency.

2. The method of claim 1, further comprising:

validating the series of movements as deliberate movements by excluding noise detected by the motion sensor.

3. The method of claim 1, further comprising:

after transmitting the subsequent set of data pings at the subsequent frequency for a time period, transmitting, by the transmitter, an updated set of data pings at the initial frequency.

4. The method of claim 1, wherein detecting the series of movements includes decomposing the data relative to the asset to recognize the series of movements.

5. The method of claim 1, further comprising:

parameterizing the series of movements to identify magnitudes and durations associated with the series of movements.

6. The method of claim 1, wherein the subsequent set of data pings are transmitted wirelessly.

7. The method of claim 6, wherein the transmitter is included in an active radio frequency (RF) tag.

8. The method of claim 1, wherein the initial frequency is predetermined.

9. The method of claim 1, wherein the subsequent set of data pings are transmitted to a receiver located remotely from the transmitter.

10. The method of claim 9, wherein the transmitter is configured to communicate bidirectionally with the receiver.

11. A wireless tracking system comprising:

a motion sensor;

a communication module;

a processor; and

a non-transitory computer-readable medium containing instructions that, when executed by the processor, cause the processor to perform operations including;

transmitting, using the communication module, an initial set of data pings at an initial frequency, wherein a data ping includes data relative to the asset;

detecting a series of movements of the asset, wherein detecting includes using the motion sensor coupled to the communication module;

creating one or more actions, wherein creating includes combining the series of movements;

correlating the one or more actions to a qualified event, wherein the qualified event is predefined by a unique pattern in the one or more actions; and

transmitting, using the communication module, a subsequent set of data pings at a subsequent frequency, wherein the subsequent set of data pings are transmitted based on the correlation of the one or more actions to the qualified event, and wherein the subsequent frequency is greater than the initial frequency.

12. The system of claim 11, wherein the operations further include:

validating the series of movements as deliberate movements by excluding noise detected by the motion sensor.

13. The system of claim 11, wherein the operations further include:

after transmitting the subsequent set of data pings at the subsequent frequency for a time period, transmitting, by the transmitter, an updated set of data pings at the initial frequency.

14. The system of claim 11, wherein detecting the series of movements includes decomposing the data relative to the asset to recognize the series of movements.

15. The system of claim 11, wherein the operations further include:

parameterizing the series of movements to identify magnitudes and durations associated with the series of movements.

16. The system of claim 11, wherein the subsequent set of data pings are transmitted wirelessly.

17. The system of claim 16, wherein the transmitter is included in an active radio frequency (RF) tag.

18. The system of claim 11, wherein the initial frequency is predetermined.

19. The system of claim 11, wherein the subsequent set of data pings are transmitted to a receiver located remotely from the transmitter.

20. The system of claim 19, wherein the transmitter is configured to communicate bidirectionally with the receiver.
