Tag based tracking with faraday cage hopper
A system includes a hopper that is a faraday cage configured to receive multiple bins capable of holding one or more parts, each bin having a wirelessly readable identifier tag with a unique digital ID. An antenna is positioned within the hopper to receive wireless signals representative of the unique digital ID of each bin placed within the hopper.
1. A system comprising:
a plurality of bins capable of holding one or more parts,
each bin of the plurality of bins having a wirelessly readable identifier tag with a unique digital ID;
a hopper comprising a faraday cage configured to receive multiple empty bins; and
a reading device comprising:
an antenna positioned to receive wireless signals representative of the unique digital ID of each bin of the multiple empty bins placed within the hopper; and
reading circuitry communicatively coupled to the antenna to convert the wireless signals to the unique digital IDs and
transmit the unique digital IDs to a management system configured to track each bin of the multiple empty bins.
2. The system of claim 1 wherein the wirelessly readable identifier tag comprises RFID tags and the reading circuitry is configured to provide energy via the antenna to the RFID tags and wherein each bin of the plurality of bins is dedicated to a particular part.
3. The system of claim 1 and further comprising a sensor positioned to detect insertion of the multiple empty bins into the hopper and trigger reception of the wireless signals from the wirelessly readable identifier tag.
4. The system of claim 1 wherein the reading circuitry is configured to periodically receive the wireless signals representative of the unique digital ID of each bin of the multiple empty bins placed within the hopper and to only transmit the unique digital ID of each bin of the multiple empty bins once placed within the hopper.
5. The system of claim 1 wherein the antenna is positioned within the hopper.
6. The system of claim 5 wherein the reading circuitry is positioned outside the hopper and is coupled to the antenna via a wired connection.
7. The system of claim 1 wherein the hopper comprises an opening configured to receive the multiple empty bins.
8. The system of claim 7 and further comprising a moveable flap configured to moveably cover the opening.
9. The system of claim 8 wherein the flap contains radio frequency blocking material.
10. A system comprising:
a hopper comprising a faraday cage configured to receive multiple bins capable of holding one or more parts,
each bin of the multiple bins having a wirelessly readable identifier tag with a unique digital ID; and
an antenna positioned within the hopper to receive wireless signals representative of the unique digital ID of each bin of the multiple bins placed within the hopper.
11. The system of claim 10 and further comprising a sensor positioned to detect insertion of each bin of the multiple bins into the hopper and trigger receiving the wireless signals from the RFID tags.
12. The system of claim 10 wherein the hopper comprises an opening configured to receive each bin of the multiple bins.
13. The system of claim 12 and further comprising a moveable flap containing radio frequency blocking material configured to moveably cover the opening.
14. The system of claim 10 and further comprising circuitry electrically coupled to the antenna, the circuitry located outside the hopper.
15. The system of claim 14 wherein the circuitry is configured to convert the wireless signals to the unique digital IDs and
transmit the digital IDs to a management system configured to track the bins.
16. The system of claim 14 wherein the circuitry is configured to periodically receive the wireless signals representative of the unique digital ID of each bin of the multiple bins placed within the hopper and to only transmit the unique digital ID of each bin of the multiple bins once the bin is placed within the hopper.
17. The system of claim 14 wherein the wirelessly readable identifier tag comprises RFID tags and the circuitry is configured to provide energy via the antenna to the RFID tags.
18. A method comprising:
detecting insertion of a bin into a hopper comprising a faraday cage;
reading a unique ID of the bin from an RFID tag associated with the bin via an antenna positioned within the hopper;
transmitting the unique ID to an inventory management system to identify the bin and enable the inventory management system to determine that the bin needs restocking.
19. The method of claim 18 and further comprising:
identifying a part to be restocked in the bin;
identifying a location to place the bin that has been restocked; and
generating an alert identifying the bin, the part to be restocked in the bin, and the location to place the bin that has been restocked.
20. The method of claim 18 and further comprising:
recording a date corresponding to every time the bin is inserted into the hopper;
determining a frequency of insertion for the bin; and
adjusting a number of parts for restocking the bin to modify a number of turns of the bin.
