Abstract

An apparatus, system, and method to manage data within a wireless network includes sending a token from a master device to a slave device, receiving an archive record only with the token at the master device from the slave device, and storing the archive record from the slave device within an archive record database at the master device.

Claims

1. A method to communicate within a wireless network comprising physical devices, the physical devices comprising a master device and a slave device, the method comprising:

determining if bandwidth available within the wireless network is above a predetermined amount at the master device;

receiving an archive record at the master device from the slave device if the bandwidth available is above the predetermined amount; and

storing the archive record from the slave device within an archive record database at the master device.

2. The method of claim 1, wherein storing the archive record comprises:

updating the archive record database at the master device with the archive record from the slave device.

3. The method of claim 1, further comprising:

comparing a master device register of the archive record database with a slave device register of the archive record database;

determining if the slave device has any archive records not received by the master device based upon the comparison; and

sending a token from the master device to the slave device if an archive record has not been received by the master device.

4. The method of claim 1, further comprising:

sending tokens from the master device to the slave device;

receiving archive records only with each of the tokens at the master device from the slave device; and

wherein each of the tokens is accompanied by a different archive record.

5. The method of claim 4, wherein the archive records are received at the master device from the slave device in an order from an oldest un-transmitted archive record to a newest un-transmitted archive record.

6. The method of claim 1, further comprising:

determining at the master device if the slave device has any tokens; and

sending a token from the master device to the slave device if determined that the slave device has no tokens.

7. The method of claim 1, further comprising:

sending a token from the master device to the slave device if the bandwidth available is above the predetermined amount;

wherein the receiving the archive record comprises receiving the archive record with the token at the master device from the slave device.

8. The method of claim 7, further comprising:

determining if bandwidth available within the wireless network is above a second predetermined amount; and

sending a second token from the master device to the slave device if the bandwidth available is above the second predetermined amount.

9. The method of claim 7, further comprising:

creating the archive record at the slave device;

wherein the slave device comprises a flow meter;

wherein the archive record comprises data of a flow rate and a property measured by the flow meter.

10. The method of claim 9, wherein the slave device creates the archive record if the master device and the slave device are not in communication with each other, and wherein the slave device sends the archive record with the token to the master device upon establishing communication between the master device and the slave device.

11. The method of claim 1, wherein:

the wireless network comprises a plurality of slave devices;

at least one of the master device and the plurality of slave devices is positioned within a hazardous area;

at least one of the master device and the plurality of slave devices is positioned within a wellsite; and

the master device comprises an explosion proof enclosure.

12. A non-transitory machine-readable medium to communicate within a wireless network comprising physical devices, the physical devices comprising a master device and a slave device, the medium comprising code, which, when executed by a machine, causes the machine to perform operations, the operations comprising:

determining if bandwidth available within the wireless network is above a predetermined amount at the master device;

receiving an archive record at the master device from the slave device if the bandwidth available is above the predetermined amount; and

storing the archive record from the slave device within an archive record database at the master device.

13. The machine-readable medium of claim 12, wherein the storing the archive record comprises:

updating the archive record database at the master device with the archive record from the slave device.

14. The machine-readable medium of claim 12, wherein the operations further comprise:

comparing a master device register of the archive record database with a slave device register of the archive record database;

determining if the slave device has any archive records not received by the master device based upon the comparison; and

sending a token from the master device to the slave device if an archive record has not been received by the master device.

15. The machine-readable medium of claim 12, wherein the operations further comprise:

sending tokens from the master device to the slave device;

receiving archive records only with each of the tokens at the master device from the slave device; and

wherein each of the tokens is accompanied by a different archive record.

16. The machine-readable medium of claim 12, wherein the operations further comprise:

determining at the master device if the slave device has any tokens; and

sending a token from the master device to the slave device if determined that the slave device has no tokens.

17. The machine-readable medium of claim 12, further comprising:

sending a token from the master device to the slave device if the bandwidth available is above the predetermined amount;

wherein the receiving the archive record comprises receiving the archive record with the token at the master device from the slave device.

18. The machine-readable medium of claim 17, wherein the operations further comprise:

creating the archive record at the slave device;

wherein the slave device comprises a flow meter;

wherein the archive record comprises data of a flow rate and a property measured by the flow meter.

19. The machine-readable medium of claim 18, wherein the slave device creates the archive record if the master device and the slave device are not in communication with each other, and wherein the slave device sends the archive record with the token to the master device upon establishing communication between the master device and the slave device.

20. A method to communicate within a wireless network comprising physical devices, the physical devices comprising a master device and a slave device, the method comprising:

comparing a master device register of an archive record database with a slave device register of the archive record database;

determining if the slave device has any archive records not received by the master device based upon the comparison;

sending a token from the master device to the slave device if an archive record has not been received by the master device;

receiving the archive record with the token at the master device from the slave device; and

storing the archive record from the slave device within the archive record database at the master device.
