Abstract

Methods and apparatus for determining a parcel position error based on a comparison of load data and configuration data are provided. Embodiments describe a number of methods of determining the parcel position error such as by determining a parcel path from the load data.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving a first set of data via a first environment sensor that reads a tag at a first position while a first parcel traverses a conveyor apparatus, the first environment sensor being located at a second position, the first set of data indicating at least the first position and the second position, the tag being coupled to a first parcel;
receiving a second set of data via a second environment sensor that reads the tag at a third position while the first parcel traverses the conveyor apparatus, the second environment sensor being located at a fourth position, the second set of data indicating at least the third position and the fourth position, the first set of data and the second set of data being a set of load data;
receiving configuration data that indicates one or more positions that the first environment sensor and the second environment sensor are expected to read any tag at; and
determining a parcel position error based on a comparison of the load data and the configuration data, wherein the comparison comprises determining that at least one of: the first position is beyond a first threshold indicated in the configuration data or the third position is beyond the first threshold or a second threshold indicated in the configuration data.

2. The computer-implemented method of claim 1 , wherein the configuration data further indicates a plurality of parcel paths, the plurality of parcel paths indicate every possible path a parcel can traverse in an environment.

3. The computer-implemented method of claim 2 , further comprising:
determining, by comparing the load data with the configuration data, that the first parcel is traversing the conveyor at a first parcel path, of the plurality of parcel paths; and
wherein the determination of the parcel position error is further based on determining that the first parcel path exceeds another threshold.

4. The computer-implemented method of claim 1 , wherein the configuration data further comprises a plurality of configuration start nodes, each configuration start node defining a first initial position of the tag; and
wherein the method further comprises:
determining a load start node from the load data defining a second initial position of the tag; and
wherein determining the first set of positions of the tag are beyond the threshold further comprises comparing the plurality of configuration start nodes and the load start node.

5. The computer-implemented method of claim 1 , wherein the configuration data further comprises a plurality of configuration end nodes, each configuration end node defining a first final position of the second set of positions of the tag of the plurality of tags; and
wherein the method further comprises:
determining a load end node from the load data defining a second final position of the first set of positions of the tag; and
wherein determining the first set of positions of the tag are beyond the threshold further comprises comparing the plurality of first end nodes to the load end node.

6. The computer-implemented method of claim 1 , wherein determining the first set of positions of the tag are beyond the threshold comprises determining a missing position for a position of the first set of positions of the tag compared to the second set of positions of the tag of the plurality of tags.

7. The computer-implemented method of claim 1 , wherein the load data further comprises a plurality of parcel IDs; and
wherein the method further comprises:
filtering the load data to comprise a single parcel ID corresponding to the tag.

8. The computer-implemented method of claim 1 , further comprising causing for display on the graphical user interface a remedial action comprising the parcel position error.

9. The computer-implemented method of claim 1 , wherein the first set of positions of the tag comprise a first scan event data of the tag, the first scan event data at the at least one of the plurality of environmental sensor positions; and
wherein the second set of positions of the tag comprise a second scan event data of each tag of the second plurality of tags, the second scan event data at the at least one of the plurality of environmental sensor positions.

10. An apparatus comprising at least one processor and at least one memory including program code, the at least one memory and the program code configured to, with the processor, cause the apparatus to at least:
receive a first set of data via a first environment sensor that reads a tag at a first position, the first environment sensor being located at a second position, the first set of data indicating at least the first position and the second position, the tag being coupled to a first parcel;
receive a second set of data via a second environment sensor that reads the tag at a third position, the second environment sensor being located at a fourth position, the second set of data indicating at least the third position and the fourth position; and
determine a parcel position error based at least in part on a comparison of the first set of data and the second set of data, wherein the comparison comprises determining that at least one of: the first position, a signal strength value, or the third position is beyond a threshold relative to one or more positions or one or more signal strength values that the first environment sensor or the second environment sensor is expected to read any tag at.

11. The apparatus of claim 10 , wherein the determining of the parcel position error comprises a comparison of a parcel path that the tag has traversed to at least one expected parcel path for the tag, the one or more positions including the expected parcel path.

12. The apparatus of claim 10 , wherein the apparatus is further caused to calculate a time difference between the first position and the third position, wherein the determining of the parcel position error is further based on the calculation of the time difference.

13. The apparatus of claim 12 , wherein the apparatus is further caused to determine a time window for the first position and the third position; and
wherein the determining of the parcel position error is further based on a comparison of the time difference to the time window.

14. The apparatus of claim 11 , wherein the parcel path of the first parcel comprises an average parcel position of the first parcel,
wherein the determining of the parcel position error is further based on a comparison of the average parcel position to the one or more positions.

15. The apparatus of claim 10 , wherein the apparatus is further caused to at least:
modify configuration data to include the at least one parcel path based on determining the parcel position error.

16. A computer-implemented method comprising:
receiving a first set of data via a first environment sensor that reads a tag at a first position while a first parcel traverses a conveyor apparatus, the first environment sensor being located at a second position, the first set of data indicating at least the first position and the second position, the tag being coupled to a first parcel;
receiving a second set of data via a second environment sensor that reads the tag at a third position while the first parcel traverses the conveyor apparatus, the second environment sensor being located at a fourth position, the second set of data indicating at least the third position and the fourth position, the first set of data and the second set of data being a set of load data;
receiving configuration data that includes a plurality of parcel paths, th
