Abstract

A method for auto-calibration of a sorter is described. The method includes transmitting, by a carrier transmit board of a sorter, a short discharge command to a first section of the sorter. The short discharge command can be generated based on a first clock offset. Further, the method includes receiving at the carrier transmit board a status message indicative of a status of a first motor control board associated with the first section of the sorter. Furthermore, in response to the status message indicating that the first motor control did not receive the short discharge command, the method includes modifying the first clock offset to a second clock offset and retransmitting the short discharge command based on a second clock offset. If the first motor control receives the short discharge command, the method includes configuring a sorter control system based on the first clock offset.

Claims (51)

1. A method for auto-calibration of a sorter, the method comprising:

transmitting, by a carrier transmit board of a sorter, a short discharge command to a first section of the sorter, wherein the short discharge command is generated based on a first clock offset, wherein the first clock offset describes a position estimate of the first section of the sorter;

in response to the transmitting of the short discharge command, receiving at the carrier transmit board a status message indicative of a status of a first motor control board associated with the first section of the sorter;

in response to the status message indicating that the first motor control did not receive the short discharge command, modifying the first clock offset to a second clock offset and retransmitting, by the carrier transmit board, the short discharge command based on a second clock offset, wherein the second clock offset describes a modified position estimate of the first section of the sorter; and

in response to the status message indicating that the first motor control received the short discharge command, configuring a sorter control system of the sorter based on the first clock offset.

2. The method of claim 1 , wherein the short discharge command is transmitted to the first motor control board associated with the first section of the sorter that is to be actuated for discharging an item.

3. The method of claim 2 , wherein the first section of the sorter corresponds to one of: a carrier of a tilt-tray sorter or a cross-belt of a cross belt sorter.

4. The method of claim 1 , wherein the short discharge command is transmitted based on a pre-defined transmit window defined for the carrier transmit board.

5. The method of claim 1 , comprising:

sending, an activation command to a plurality of carrier transmit boards of the sorter;

receiving, an activation acknowledgement respectively from a set of the carrier transmit boards from amongst the plurality of carrier transmit boards; and

activating the set of carrier transmit boards.

6. The method of claim 1 , wherein modifying the first clock offset comprises one of:

increasing the first clock offset by a first predetermined value; and

decreasing the first clock offset by a second predetermined value.

7. A system comprising:

a processor configured to:

transmit, by a carrier transmit board of a sorter, a short discharge command to a first section of the sorter, wherein the short discharge command is generated based on a first clock offset, wherein the first clock offset describes a position estimate of the first section of the sorter;

in response to transmitting of the short discharge command, identify a receiving of a status message at the carrier transmit board, wherein the status message is indicative of a status of a first motor control board associated with the first section of the sorter;

in response to the status message indicating that the first motor control did not receive the short discharge command, modify the first clock offset to a second clock offset and retransmit, by the carrier transmit board, the short discharge command based on a second clock offset, wherein the second clock offset describes a modified position estimate of the first section of the sorter; and

in response to the status message indicating that the first motor control received the short discharge command, configure a sorter control system of the sorter based on the first clock offset.

8. The system of claim 7 , wherein the short discharge command is transmitted to the first motor control board associated with the first section of the sorter that is to be actuated for discharging an item.

9. The system of claim 8 , wherein the first section of the sorter corresponds to one of: a carrier of a tilt-tray sorter or a cross-belt of a cross belt sorter.

10. The system of claim 7 , wherein the short discharge command is transmitted based on a pre-defined transmit window defined for the carrier transmit board.

11. The system of claim 7 wherein the processor is configured to:

send an activation command to a plurality of carrier transmit boards of the sorter;

receive an activation acknowledgement respectively from a set of the carrier transmit boards from amongst the plurality of carrier transmit boards; and

activating the set of carrier transmit boards.

12. The system of claim 7 , wherein the processor is configured to modify the first clock offset based on one of:

increasing the first clock offset by a first predetermined value; and

decreasing the first clock offset by a second predetermined value.

13. A sorter system comprising:

a carrier transmit board;

a sorter control unit communicatively coupled to the carrier transmit board, the sorter control unit comprising a processor configured to:

transmit, by the carrier transmit board, a short discharge command to a first section of a sorter, wherein the short discharge command is generated based on a first clock offset, wherein the first clock offset describes a position estimate of the first section of the sorter;

in response to transmitting of the short discharge command, identify a receiving of a status message at the carrier transmit board, wherein the status message is indicative of a status of a first motor control board associated with the first section of the sorter;

in response to the status message indicating that the first motor control did not receive the short discharge command, modify the first clock offset to a second clock offset and retransmit, by the carrier transmit board, the short discharge command based on a second clock offset, wherein the second clock offset describes a modified position estimate of the first section of the sorter; and

in response to the status message indicating that the first motor control received the short discharge command, configure a sorter control system of the sorter based on the first clock offset.

14. The sorter system of claim 13 further comprising:

a plurality of motor control boards associated with respective item carrier sections of the sorter, the plurality of motor control boards comprising the first motor control board.

15. The sorter system of claim 13 , wherein the short discharge command is transmitted to the first motor control board associated with the first section of the sorter that is to be actuated for discharging an item.

16. The sorter system of claim 15 , wherein the first section of the sorter corresponds to a carrier of a tilt-tray sorter.

17. The sorter system of claim 15 , wherein the first section of the sorter corresponds to a carrier of a cross belt sorter.

18. The sorter system of claim 13 , wherein the short discharge command is transmitted based on a pre-defined transmit window defined for the carrier transmit board.

19. The sorter system of claim 13 , wherein the processor is configured to:

send an activation command to the carrier transmit board;

receive an activation acknowledgement from the carrier transmit board; and

activate the carrier transmit board based on receiving of the activation acknowledgement.

20. The sorter system of claim 13 , wherein the processor is configured to modify the first clock offset based on one of:

increasing the first clock offset by a first predetermined value; and

decreasing the first clock offset by a second predetermined value.
