Abstract

The present invention relates to a fully automatic method and a system for distribution monitoring of shipments and automatic location assignment of objects with virtual location information and wireless technology.

Claims

1. A system to automatically assign items to a location of some meaning in a distribution network, comprising of:

a. wireless active ID tags assigned to an item(s) in the distribution network, said wireless active ID tags comprising;

a memory

a processor

a wireless communication module

wherein the wireless active ID tags store a last location information in its memory and updates the last location once it enters a new location other than its last location,

b. one or more transport vessels, equipped with one or many transceivers, wherein each transceiver is assigned to a location and said transceiver comprising;

a memory

a processor

a wireless communication module

c. a network connection to a centralized database to

store information relating to the items and the wireless IDs associated to the items

store location definitions and transceivers associated to said locations,

receive and store location information data from transceivers,

wherein each transceiver communicates with one or more wireless active ID tags and where automatic communication of data between wireless active ID tags, transceivers and centralized database is performed by a wireless communication protocol, and

wherein assigning an item to a location is performed by

i. updating the location of all wireless active ID tags at a new location in the transceiver in the transport vessel,

ii. updating the presence of all wireless active ID tags at in the transport vessel after leaving the location, and

iii. issuing an event indicating which items were loaded off at the last location and which items were loaded on at the last location.

2. The system according to claim 1, wherein the transceiver in the transport vessel identifies all wireless active ID tags at a new location inside and outside the transport vessel.

3. The system according to claims 1 and 2, wherein the transceiver unit uses geographic positioning information to determine that the transport vessel has left the last location and to issue an event indicating which items were loaded off at the last location and which items were loaded on at the last location.

4. The system according to claim 1-3, wherein the transceiver unit uses a pre-determined time period to determine that the transport vessel has left the last location and to issue an event indicating which items were loaded off at the last location.

5. The system according to claims 1-4, wherein the transceiver obtains information using geographical information associated with a location from the centralized database.

6. The system according to claim 5, wherein the transceiver collects information on multiple locations in a region where the transceiver is located and stores the collected information in memory to reduce the load on the centralized database.

7. The system according to claim 5, wherein the transceiver learns which locations it uses frequently in the event that the transceiver is unable to connect the centralized database.

8. The system according to any of the preceding claims, wherein the unique id of each transceiver determines physical location information of a destination location in a centralized database.

9. The system according to any of the preceding claims, wherein the geographical location of each transceiver unit is determined by a geographical coordinate in the centralized database.

10. The system according to any of the preceding claims, wherein multiple locations, located at the same coordinates, are grouped together as a single destination location.

11. A system according to claim 9, wherein transceivers are aware of other locations in its vicinity and base the decision whether or not to issue events on that awareness.

12. The system according to any of the preceding claims, wherein the event contains more than one destination location ID, indicating that multiple locations might be relevant as the destination location where each location sent with the event is ranked.

13. The system according to claim 12, wherein the centralized database uses additional information on locations, stored in the centralized database, to estimate the likeliest destination location from the list of locations sent with the event.

14. The system according to any of the preceding claims, wherein the wireless active ID tag contains a sensor to obtain measurements, accumulate the measurements into memory and transmit them to a centralized database.

15. The system according to any of the preceding claims, wherein the location information contains information on the role of the location in the distribution network.

16. The system according to any of the preceding claims, wherein the item information in the centralized database contains;

reference to the item or product being transported

the content of the item

the value of the content

lifetime of the content
