Conveying systems and methods of associating data with an item transported by a conveying system
Systems and methods of associating data to an item being transported by a conveying system are disclosed. The item and data associated with the item are received at a first zone of the conveying system. The data is stored in a first computer-readable storage medium associated with the first zone. The item is transported to a second zone of the conveying system, and the data stored in the first computer-readable storage medium is transferred to a second computer-readable storage medium associated with the second zone.
1. A method of associating data with an item being transported by a conveying system, the method comprising:
receiving the item at a first zone of the conveying system, wherein the item comprises an associated data tag, wherein the first zone comprises a first local controller;
receiving, by the first local controller, data associated with the item, wherein the data comprises an expected value for a property of the item;
sensing a value for the property of the item;
comparing, by the first local controller, the expected value for the property with the sensed value for the property;
in response to the comparing satisfying a threshold condition:
transporting the item to a second zone of the conveying system, wherein the second zone comprises a second local controller, and
transferring the data from the second local controller to the third local controller; and
in response to the comparing not satisfying the threshold condition, transporting the item to a third zone of the conveying system.
2. The method of claim 1 , wherein the property comprises a weight of the item.
3. The method of claim 1 , wherein the property comprises one or more dimensions of the item.
4. The method of claim 1 , wherein the data further comprises the actual value for the property.
5. A conveying system comprising:
a first zone comprising:
a first conveyor section configured to transport an item, and
a first local controller;
a second zone comprising:
a second conveyor section configured to transport an item, and
a second local controller;
wherein the first zone is configured to receive the item, wherein the item comprises an associated data tag;
wherein the first local controller is configured to:
receive data associated with the item, wherein the data comprises an expected value for a property of the item,
sense a value for the property of the item, and
compare the expected value for the property with the sensed value for the property, and
in response to the comparison satisfying a threshold condition:
transport the item to a second zone of the conveying system, wherein the second zone comprises a second local controller, and
transfer the data from the first local controller to the second local controller; and
in response to the comparison not satisfying the threshold condition, transport the item to a third zone of the conveying system.
6. The system of claim 5 , wherein the property comprises a weight of the item.
7. The system of claim 5 , wherein the property comprises one or more dimensions of the item.
8. The system of claim 5 , wherein the data further comprises the actual value for the property.
