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.
