Abstract

A system for managing data related to at least one leaf node device, the system including a location processing engine located on a server that is remote from the at least one leaf node device; at least one point of interest (POI) device for collecting data relating to at least one leaf node device and transmitting the collected data with a timestamp using Bluetooth Low Energy (BLE); at least one reader node device for receiving the collected data from the point of interest (POI) device using BLE and transmitting the collected data to the location processing engine; and a database of the known locations of POI devices, wherein the known locations are used as a basis for determining the location of the at least one leaf node device that communicated with the POI device.

Claims

1. A system for managing data related to at least one leaf node device, comprising:

a location processing engine located on a server that is remote from the at least one leaf node device;

at least one point of interest (POI) device for collecting data relating to at least one leaf node device and transmitting the collected data with a timestamp using Bluetooth Low Energy (BLE);

at least one reader node device for receiving the collected data from the point of interest (POI) device using BLE and transmitting the collected data to the location processing engine; and

a database of the known locations of POI devices, wherein the known locations are used as a basis for determining the location of the at least one leaf node device that communicated with the POI device.

2. The system of claim 1, wherein the point of interest (POI) device uses one of an omnidirectional antenna and a directional antenna.

3. The system of claim 1, wherein the collected data is at least one of signal strength information, proximity information and phase angle information.

4. The system of claim 3, wherein the collected data is collected via BLE communication signals from the leaf node device.

5. The system of claim 1, wherein the collected data is used as a basis for determining the location of the at least one leaf node device.

15. The system of claim 1, wherein the collected data is at least one of signal strength information, proximity information and phase angle information.

6. A method for real time location of at least one leaf node device, comprising:

taking at least one of signal strength information, proximity information and phase angle information collected via Bluetooth Low Energy communication signals from the leaf node device;

delivering the collected information to a processing engine that is remote from the leaf node device; and

processing the collected information in real time to determine the location of the leaf node.

7. The method of claim 6, further comprising time stamping the collected information with the time of collection.

8. The method of claim 6, further comprising delivering to the processing engine at least one of identification and location information relating to the point of interest device that collected the information from the leaf node device.

9. The method of claim 6, wherein the information about the leaf node device is collected by at least two collection devices wherein each collection device is from the group consisting of reader nodes and point of interest devices.

10. The method of claim 8, further comprising processing the collected information together with the location information about the point of interest device to determine the location of the leaf node device.

11. The method of claim 9, further comprising calculating an average location for a leaf node device based on two or more determinations of location for the leaf node device, wherein each of the determinations of location is based on data from a different one of the two or more collection devices.

12. The method of claim 6, further comprising storing the calculated average location of the leaf node device in a database.

13. A system for managing assets, comprising:

a leaf node device associated with an asset;

a plurality of POI devices each at known locations, the POI devices each having a respective boundary and collecting data relating to the asset when the leaf node device is within the respective boundary;

a location processing engine remote from the leaf node device and the plurality of POI devices; and

a database of known locations of the POI devices,

wherein each POI that has collected data relating to the asset communicates the collected data relating to the asset to the location processing engine,

wherein the location processing engine accesses the database and determines the location of the asset based on the collected data related to the asset and known locations of the POI devices.

14. The system of claim 13, wherein the point of interest (POI) device uses one of an omnidirectional antenna and a directional antenna.

16. The system of claim 13, wherein the collected data is collected via BLE communication signals from the leaf node device.

17. The system of claim 13, further comprising a sensor associated with the asset, the sensor detecting data of a condition of said asset.

18. The system of claim 17, wherein the collected data relating to the asset comprises said data of a condition of said asset.

19. The system of claim 13 further comprising a remote server in communication with the plurality of POI devices.

20. The system of claim 19 wherein the location processing engine is on the remote server.
