Overview of Use: RFRain partnered with Infinity Robotics to implement an RFID scanner on a complex conveyor belt to allow boxes to be routed to the appropriate location.
Identified Problem: Barcode scanners have a lot of drawbacks over an RFID scanner including:
– Inability to scan the proper tag when multiple tags are placed on the box.
– Scanning may not be accurate in case the tag is damaged.
– The tag has to be placed on the same side as the scanner for maximum accuracy.
On the other hand an RFID implementation provides with the following advantages when an asset is already tagged
with an RFID tag or your company plans on using RFID.
– Ability to scan the proper tag when multiple tags are present.
– Scanning is always accurate at a rate of 99%.
– The reader is able to read the tag in any location and any orientation.
– A smart reader from RFRain makes interfacing with the Ignition software from SIEMENS a breeze, since the.
communication is achieved using JSON based REST API.
– Pre-installed proximity based algorithms such as the counting algorithms or RSSI filtering allows no RF interference.
Solution: Install an RFRain smart reader with 4 antennas on a scanning location. Wrap the area around the antenna
and reader with an inexpensive RFID shield. The shield does not have to be perfect, since the pre-installed software on
the reader makes the tag reading 99% accurate.
Outcome: Using RFRain’s counting and RFID algorithm allowed our customer to reach 99% accuracy on routing large and small boxes tagged with an RFID tag to their proper location.
Technology Used:
Hardware:
RFRain installed an RFR-RAIN-4-SMART reader with 4 antennas.
Software: RFR-ZM-Manager with couting and RSSI pre-installed algoritms.
Conveyor Belt Software: Ignition software interfacing directly with the reader using Rest API’s.
