Tracking a mobile unit in a housing facility for mobile units

摘要

A mobile unit in a housing facility for mobile units may be tracked by activating a first reading device at a first location of the housing facility upon detecting a first mobile unit arriving at or departing from the first location, wherein the first mobile unit has a first tag having an identification code (ID) readable by the first reading device. A set of readings may be performed by the first reading device to read a set of tag IDs during a time interval. Upon an ending of the time interval, tag IDs, in the set of tag IDs, that correspond to the first tag ID are identified based on the set of readings. A record is updated to associate the first tag ID with the first location.

主权项

1. A computer implemented method for tracking a mobile unit in a housing facility for mobile units, the method comprising:
in response to receiving a signal from a detector associated with a first location, activating a first reading device having a reading range that includes at least the first location; receiving a first set of tag IDs from the first reading device, read during a first time interval; and in response to determining that two or more of the tag IDs in the first set of tag IDs can be associated with the first location, initiating a conflict resolution step to select a single tag ID, of the first set of tag IDs, for the first location, wherein initiating a conflict resolution further comprises:
determining that one of the tag IDs in the first set of tag IDs cannot be associated with the first location is based a number of instances of two or more of the tag IDs in the first set of tag IDs being within a threshold range;activating one or more second reading devices, each having a reading range that includes at least the first location, wherein the reading range of at least one of the second reading devices is different from the reading range of the first reading device;receiving a second set of tag IDs from the second reading devices read during a second time interval; andidentifying a tag ID that is read by a highest number of the second reading devices and associating the identified tag ID with the first location.
