Application of RFID technology in UAV
In recent years, with the increasing application of RFID technology in life, some technology companies have combined drones with RFID (radio frequency identification) technology to improve the intelligence of drones. Drone delivery has become a trend, and Amazon, SF, etc. are all testing. In addition to delivery, drones play a role in many applications, enabling drones to read data during flight.
A California Polytechnic State University (Cal Poly) research project found that drones using RFID readers can read tags attached to steel drills or utility pipes with 95% to 100% accuracy. Oilfields usually need to store thousands of pipe fittings (steel pipes used for drilling operations). These pipe fittings are stored in different areas of the oilfield, so inventory management is a very time-consuming task. Using RFID technology, when the RFID reader is within the range of the electronic tag marking items, it can be read.
However, in a large storage site, the deployment of fixed readers is not realistic, and regular use of handheld readers is also time-consuming to read. By attaching RFID tags to dozens of tube caps or pipe insulators, UAVs with UHF readers can usually read passive UHF RFID tags at a distance of about 12 feet. This solution not only solves the error of manual management, but also greatly improves the work efficiency. However, in large storage areas, customers need to arrange a dedicated person to "watch" the drone in order to replace the battery in time.
The MIT research team has achieved a more convenient inventory search by combining RFID technology and drones. Compared to barcodes, the information contained on RFID tags can be changed more widely and easily, and it is also cheaper.
Drones equipped with RFID card readers can replace stocked characters and complete tasks faster with less hassle. A tall box where a person needs a ladder or elevator to enter can be easily reached by a drone, the drone can be programmed to navigate the space independently, and they are more accurate and efficient than manual repetitive tasks than manual Better management.
By equipping the drone with a tiny relay, it acts like a Wi-Fi repeater. The drone receives the signal sent from the remote RFID reader and then forwards it to read nearby electronic tags. Because the relay is small, it means that smaller drones can be used, plastic parts can be used, and it can be adapted to a narrow space without causing danger of personal injury. This not only eliminates additional RFID readers, but also allows Small drones do the same job as large drones.
The combination of RFID technology and drones can manage inventory and coordinate the supply chain, benefiting from the deployment of radio frequency identification in the warehouse. RFID drones help staff improve efficiency, reduce labor costs, optimize inventory levels, and track assets.
