1 Overview
With the continuous deepening of the domestic economic reform and opening up, the domestic civil aviation industry has achieved unprecedented development. The number of passengers entering and leaving the airport continues to increase, and the luggage throughput has reached a new height. The handling of baggage has always been a huge and complicated task for large airports. In particular, the ongoing terrorist attacks against the aviation industry also put forward higher requirements for baggage identification and tracking technology. How to manage piles of luggage and effectively improve handling efficiency is an important issue faced by airlines.
2. Background
In response to the new challenges that passenger baggage poses to the processing capacity of the airport conveyor system, Trimble & ThingMagic’s agent Shenzhen Quanshunhong Technology Co., Ltd. brought ThingMagic UHF RFID read-write modules to major operators and integrators. High-frequency RFID reading and writing equipment is being used in automatic baggage sorting systems in more and more airports. This system uses barcode labels to identify passenger luggage. During the transportation process, it achieves the sorting process of passenger luggage by identifying the barcode. The baggage tracking system of global airlines has developed to the present and is relatively mature. However, even under the most ideal conditions, the barcode system can only correctly read 8 to 9 pieces of baggage, which means that airlines have to Continuously invest a lot of time and energy in manual operations to transport the sorted baggage to different flights. At the same time, because bar code scanning requires high directionality, this also adds extra workload to airport staff when performing bar code packaging.
Simply using barcodes to match and sort luggage will be a task that requires a lot of time and energy, and may even cause serious flight delays.
Improving the degree of automation and sorting accuracy of the airport baggage automatic sorting system is of great significance to protect public travel safety, reduce the work intensity of airport sorting personnel, and improve the overall operating efficiency of the airport.
RFID radio frequency identification technology is generally regarded as one of the most promising technologies in the 21st century. It is a new technology that has caused changes in the field of automatic identification after barcode technology. Its non-line-of-sight, long-distance, low directivity, fast and accurate wireless communication capabilities have been increasingly focused on the airport baggage automatic sorting system. Finally, in October 2005, IATA (International Air Transport Association) unanimously passed a resolution to adopt UHF (ultra-high frequency) RFID strap-on tags as the only standard for aviation luggage tags.
3. System Architecture
The RFID baggage automatic sorting system is to paste the baggage randomly checked by each passenger on the planeRFIDElectronic tags, which record passenger personal information, port of departure, port of arrival, flight number, parking space, departure time and other information; electronic tag readers are installed on various control nodes of baggage flow, such as sorting, loading, and baggage claim Writing equipment. When the baggage with tag information passes through each node, the RFID reader will read the information and send it to the database. Realize the information sharing and monitoring of baggage in the whole transportation process. The system architecture diagram is as follows:

4. System Flow
Passengers departing from the airport check their baggage at the departure check-in counter. The staff completes the check-in registration and prints the RFID baggage tag according to the passenger boarding pass, installs the RFID baggage tag on the baggage and puts it on the baggage conveyor. The conveyor is equipped with an RFID collection channel. When the baggage passes through the RFID collection channel, its related information is collected and uploaded to the conveyor control system. The conveyor control system can sort the baggage correctly to the corresponding flight based on the obtained information. The luggage room is not well. Finally, the porter transfers the baggage of the corresponding flight to the luggage compartment, and enters the cargo hold of the plane with the tractor.

The automatic baggage sorting system at the airport uses RFID technology, which uses electronic tags to identify baggage and uses radio frequency signals to automatically identify the target baggage. Even multiple high-speed moving baggage objects can be simultaneously identified without manual intervention, and the operation is quick and convenient. The mechanization rate of RFID technology can reach more than 95%, which means that technically, the possibility of baggage loss, late delivery, and wrong delivery will be greatly reduced. At the same time, RFID can work in a variety of harsh environments. In this way, the luggage safety of passengers can be strengthened, and the error rate and other problems can be greatly reduced.
In addition, each RFID reader can be connected to the server through the network, and it can effectively record, track and monitor from all aspects of baggage check to the final delivery of the luggage. The entire process can be grasped in time, and the management is performed dynamically. Based on this statistical data and checking the situation of each link, targeted management can be achieved, and the information and intelligence of airport baggage management can be improved as a whole.
5. System key technology
The air baggage automatic sorting system should aim to achieve maximum efficiency, safety, reliability, and ease of maintenance. In the entire system, RFID data collection is particularly critical.
High-speed data collection
In order to meet the increasing number of passenger luggage at airports, especially in large and medium-sized airports, the conveying speed of conveyors is increasing. Higher transmission speeds have higher requirements for the collection speed of RFID readers;
stability
The automatic baggage sorting system of aviation and airport operates continuously 24 hours a day, 365 days a year, and RFID equipment must meet the stable operation in this environment.
reliability
The baggage sorting system must accurately obtain the information of each piece of baggage in order to correctly complete the sorting, which requires the RFID equipment to have very high reliability and accurately collect the information of each piece of baggage;
compatibility
The core control part of automatic baggage sorting system generally adopts PLC. In order to achieve the purpose of high-speed and accurate sorting, how the PLC can obtain the data collected by the RFID device is also very important, which also requires that the RFID device must be compatible with the PLC. RFID devices that support instruction set control can be well compatible with PLC.
6. Product selection
According to the requirements of the airport baggage automatic sorting system for RFID equipment, the system equipment selection adopts ThingMagic M6 or UHF RFID reader integrated with ThingMagic M6e module.
ThingMagic M6/M6E UHF RFID equipment has a high-speed reading capability of 750 tags/s, which can adapt to normal reading in scenarios with a speed of 180Km/h and meet the requirements of the airport baggage automatic sorting system for data collection speed. ThingMagic M6/M6E four channelsReader, It can connect up to 4 antennas to work at the same time, the coverage is wider, and the luggage tag can be read from multiple angles, which greatly improves the reliability. At the same time, ThingMagic M6/M6E has super anti-interference ability and can adapt to various harsh industrial environments. The dual optimization of good power consumption and heat dissipation can ensure the long-term continuous power and stable operation of the equipment, which is suitable for the stability of the airport baggage sorting system. Requirements. In addition, ThingMagic M6/M6E especially supports instruction set control, which can be well connected with the PLC system, the development is the simplest, the cycle is the shortest, and the application is the most stable.
As the agent of ThingMagic, the leading RFID brand, Shenzhen Quanshunhong Technology Co., Ltd. has cooperated with major operators and integrators to successfully use ThingMagic RFID equipment in aviation shipping, warehousing and logistics, clothing retail, manufacturing, In various applications such as anti-counterfeiting and traceability, the company provides customers with world-class RFID equipment solutions and high-quality after-sales service with a professional technical team, high-quality service, and preferential prices.
