HIERARCHY OF RFID TAGS FOR ACCESSING HISTORY AND OTHER DATA
A hierarchical configuration of RFID tags. The hierarchical configuration includes a plurality of RFID tags having lower level RFID tags, intermediate level RFID tags and at least one upper level RFID tags, where each RFID tag stores an identification code and other information about the thing it is attached to. Further, each intermediate level RFID tag also obtains information about a group of lower level RFID tags that it is associated with and the at least one upper level RFID tag obtains information about more than one intermediate RFID tag it is associated with.
1 . A hierarchical configuration of RFID tags comprising a plurality of RFID tags including lower level RFID tags, intermediate level RFID tags and at least one upper level RFID tag, each RFID tag storing information identifying that RFID tag and a thing it is attached to, wherein each intermediate level RFID tag also stores information about a group of lower level RFID tags and things they are attached to that it is associated with and the at least one upper level RFID tag obtains information about more than one intermediate level RFID tag it is associated with, and wherein each of the intermediate level RFID tags and the at least one upper level RFID tags being interrogated to transmit its stored information.
2 . The configuration according to claim 1 wherein the intermediate level RFID tags and the at least one upper level RFID tag store historical information that was previously associated with that RFID tag.
3 . The configuration according to claim 1 wherein the lower level RFID tags are attached to products.
4 . The configuration according to claim 3 wherein the intermediate level RFID tags are attached to containers where the products are stored in the containers.
5 . The configuration according to claim 4 wherein the at least one upper level RFID tag is attached to a truck where the containers are on the truck.
6 . The configuration according to claim 5 wherein the upper level RFID tag stores information about containers that have been removed from the truck.
7 . The configuration according to claim 5 wherein the intermediate level RFID tags store information concerning previous trucks that the containers where on.
8 . The configuration according to claim 1 wherein the hierarchical configuration of RFID tags is used for plant floor management and vehicle assembly operations.
9 . The configuration according to claim 1 wherein the at least one upper level RFID tag is implemented in software.
10 . A hierarchical configuration of RFID tags comprising a plurality of RFID tags at more than one hierarchical layer, wherein a plurality of the plurality of RFID tags obtains information about particular things at a lower level of the hierarchical configuration and at least one RFID tag of the plurality of RFID tags obtains information about a plurality of the things having RFID tags at the lower level.
11 . The configuration according to claim 10 wherein the RFID tags store historical information that was previously associated with the RFID tag.
12 . The configuration according to claim 10 wherein the lower level RFID tags are attached to products.
13 . The configuration according to claim 12 wherein intermediate level RFID tags are attached to containers where the products are stored in the containers.
14 . The configuration according to claim 13 wherein an upper level RFID tag is attached to a truck where the containers are on the truck.
15 . The configuration according to claim 14 wherein the upper level RFID tag stores information about containers that have been removed from the truck.
16 . The configuration according to claim 13 wherein the intermediate level RFID tags store information concerning previous trucks that the containers where on.
17 . The configuration according to claim 10 wherein the hierarchical configuration of RFID tags is used for plant floor management and vehicle assembly operations.
18 . The configuration according to claim 10 wherein the at least one upper level RFID tag is implemented in software.
19 . A hierarchical configuration of RFID tags comprising a plurality of RFID tags at more than one hierarchical layer where upper level RFID tags store information about lower level RFID tags, said hierarchical configuration of RFID tags being used for plant floor management and vehicle assembly operations.
20 . The configuration according to claim 19 wherein the RFID tags store historical information that was previously associated with the RFID tag.
