Application of Ultra High Frequency RFID in Airport Luggage Automatic Sorting System

Application of Ultra High Frequency RFID in Airport Luggage Automatic Sorting System

Apr 10,2023

With the continuous deepening of domestic economic reform and opening up, the domestic civil aviation industry has achieved unprecedented development, with an increasing number of passengers entering and leaving the airport, and baggage throughput reaching a new height. The handling of luggage has always been a huge and complex task for large airports, especially with the continuous occurrence of terrorist attacks against the aviation industry, which also puts higher requirements on luggage identification and tracking technology. How to manage the mountains of luggage and effectively improve handling efficiency is an important issue faced by airlines.


 Improving the automation and sorting accuracy of the airport baggage automatic sorting system is of great significance for protecting public travel safety, reducing the workload of airport sorting personnel, and improving the overall operational efficiency of the airport. RFID wireless radio frequency identification technology is widely regarded as one of the most promising technologies in the 21st century, and it is a new technology that has led to changes in the field of automatic identification after barcode technology. Its non line of sight, long-distance, low directional requirements, and fast and accurate wireless communication capabilities are increasingly being focused on airport baggage automatic sorting systems. Finally, in October 2005, the International Air Transport Association (IATA) unanimously adopted a resolution to take UHF (Ultra High Frequency) RFID strapping tags as the only standard for aviation baggage tags.

The airport baggage automatic sorting system uses RFID technology to identify luggage through electronic tags, and uses wireless radio frequency signals to automatically identify target luggage. Even for multiple high-speed moving luggage objects, they can be identified simultaneously without manual intervention, making the operation fast and convenient. The mechanization rate of using RFID technology can reach over 95%, which means that the possibility of lost, delayed, and mistakenly transported luggage will be greatly reduced from a technical perspective. Meanwhile, RFID can work in various harsh environments. This can enhance the safety of passengers' luggage and greatly reduce their error rate and other issues.

In addition, each RFID reader and writer can be connected to the server through the network, effectively recording, tracking, and monitoring the entire process from baggage check-in to passengers' hands, timely grasping the entire process, and dynamically managing it. Management personnel can fully rely on this statistical data and view the situation of each link to achieve targeted management, improving the overall informatization and intelligence of airport baggage check-in management.

 Advantages of RFID system


 The automatic baggage sorting system for aviation should aim to achieve maximum efficiency, safety, reliability, and ease of maintenance. RFID data collection is particularly crucial in the entire system.

1. High speed data collection

 In order to meet the increasing number of passengers' luggage at airports, especially large and medium-sized airports, the conveyor speed is becoming increasingly high-speed. Higher transmission speed has higher requirements for the collection speed of RFID readers and writers; The UHF RFID reader can simultaneously recognize and read multiple RFID electronic tags.

 2 Stability

 The automatic baggage sorting system at the airport operates 24 hours a day, 365 days a year, and RFID equipment must meet the stable operation requirements in this environment.

 3 Reliability

 The baggage sorting system must accurately obtain information about each piece of luggage in order to complete the sorting process correctly, which requires RFID equipment to have very high reliability and accurately collect information for each piece of luggage.

 4. Reusability of RFID tags

 Most barcodes cannot be changed after printing, while RFID tags can repeatedly add, modify, and delete data stored in RFID labels, facilitating information updates.

 5 Penetration and Barrier Free Reading

 When covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood, and plastic, and can conduct penetrating communication. And barcode scanners must be at close range and without object obstruction in order to recognize barcodes.

 6. Strong pollution resistance and durability

 The traditional barcode carrier is paper, which is prone to contamination, while RFID tags store data in the chip, so it can be free from contamination.

 7 Safety

 Due to the electronic information carried by RFID, its data content can be password protected, making it less susceptible to forgery and alteration.

    The RFID reader (reader writer) communicates wirelessly with RFID electronic tags through an antenna, enabling the reading or writing of tag identification codes and memory data. A typical reader includes a high-frequency module (transmitter and receiver), a control unit, and a reader antenna.

    The anti removable ceramic RFID electronic tag uses a composite ceramic substrate inside, which is resistant to high temperature and has stable performance. Ceramic labels are inherently fragile, making them highly suitable for applications that prevent disassembly and tearing. The combination of anti disassembly ceramic labels with automotive glass can achieve excellent readability performance.
