Radio Frequency Identification (RFID) technology is an innovative application of modern science and technology in all aspects of society. As one of the top ten technologies with the greatest development potential in the 21st century, the development of RFID technology has brought huge market value. RFID technology has been widely used in many fields such as retail, logistics, and manufacturing. In the aviation field, due to the cooperation of aircraft manufacturers, component suppliers and airlines, RFID technology has penetrated into all aspects of the aviation supply chain system, but overall, RFID technology started late in the aviation field, in China's aviation The application of the field started later. It is of great significance to carry out research on RFID technology in the aviation field.
1. Application of radio frequency identification technology in the aviation field
The application of RFID technology in the aviation field, according to major categories, is currently divided into three major directions, including aerospace manufacturing, aviation operations and maintenance, and airport management.
1.1 in aerospace manufacturing applications
In the field of aerospace manufacturing, especially in the mainframe manufacturing enterprises, there are many types of parts and tools, and the number of parts and tools is large. The process route is complex and variable, the production cycle is long, and the finished products need to be processed and assembled in parts. Many parts may need dozens of parts. The process can be produced, involving many workshops and outsourcing manufacturers. The production process is complex. To maintain production, a series of scientific cooperation, such as raw materials, equipment, fixtures, warehouses, and operators, is required, involving various departments and suppliers of enterprises, and the production process organization is extremely complicated.
1.2 Application in aviation operations and maintenance
1) Aviation material management
The variety and quantity of aviation materials continue to increase, resulting in increased difficulty in the management of aviation materials and increased complexity. The management of aviation materials is different from the general materials. The price is relatively expensive. If the aviation materials are not adequately supplied, it will inevitably have an adverse impact on aviation maintenance. The vicious circle caused by it will be difficult to make up. The storage of aviation materials should be controlled within an ideal limit. Too many materials will inevitably lead to a state of chaos in the airline's finances, which will adversely affect the overall development of the aviation industry. Therefore, in the management of aviation materials, it is necessary to consider various factors to complete the ideal control.
2) Maintenance management
In the development of aviation industry, maintenance is a relatively core part. The complexity of aircraft system determines the need for more maintenance tools and ground support equipment in modern aviation maintenance. The effective control of these tools and equipment becomes normal maintenance work. The material type preconditions carried out directly affect the efficiency and efficiency of maintenance, and also reflect the maintenance management ability and maintenance level of aviation maintenance enterprises . How to effectively control these tools and equipment is a major issue facing aviation maintenance companies. The research on the application of RFID technology to the management of aviation maintenance tools has been deepened, and related commercial hardware products have also emerged, providing conditions for efficient management of maintenance tools.
3) Lifesaving equipment management
After the oxygen generator is installed on the aircraft, it is often required to perform routine inspections on a large number of labors to prevent equipment from being overdue. Before using RFID technology, the staff must open the panel above the seat to check the date of the oxygen generator. Therefore, in practical applications, in order to avoid the overdue, many oxygen generators are completely replaced when they are not expired. Reduces the life of the equipment and increases operating costs.
1.3 Application in airport management
1) Airport baggage management
Airports and airlines are working to use RFID to enhance baggage tracking, distribution and transmission. Compared with the traditional baggage bar code management, the RFID baggage management system can read the tags from a long distance, and the recognition speed is faster and the result is more accurate, so that the baggage handling system of the airport can track the baggage more accurately and help the baggage to be delivered in time.
An electronic ticket is an electronic form of a paper ticket. It stores the ticket information in the reservation system, and can perform the operations such as issuing tickets, invalidating, refunding, changing the transfer, etc. like a paper ticket. Passengers do not need to get a traditional paper ticket, as long as they use the ID card and the electronic ticket order number, they can get the boarding pass directly on the plane at the airport airline's special counter one hour before the plane takes off, thus avoiding the ticket. Lost or forgotten, you can't board the plane.
3) Vehicle monitoring and dispatching in the airport
The on-site vehicle monitoring command and dispatch system based on GPS/BDS/GLONASS, RS, RFID, GIS, network technology and database technology has been widely used in large airports at home and abroad.
In particular, RFID has been successfully applied to airport freight management, which enables real-time, accurate and complete recording and tracking of goods. It can comprehensively and efficiently strengthen the management from production, transportation to sales, and provide various improvements. Easy-to-use functions such as query, statistics, and data analysis. Each item can be set up with complete information within the network, and the content, lines and logs of the goods tracking and management can be seen at a glance.
4) Security management
The application of RFID in security prevention mainly includes: airport security management, employee management, and crossing vehicle management. Through RFID technology, the blacklist can send a warning signal when passing the checkpoint, and quickly indicate the person's baggage, so that the manager can find out the baggage to do the relevant work in time and accurately, and better prevent the terrorist incident.
2. Status of standardization of RFID technology in the aviation field
In terms of the development of RFID basic standards, the two major international standards organizations (ISO/IEC) and EPC global have established a relatively complete set of radio frequency identification standards, including air interface protocol standards and protocol conformance test standards. , label data standards, etc.
3. Particularity of RFID applications in the aviation field
Different from general RFID applications, the application of RFID in the aviation field has certain specialities. First of all, the application environment is different. The RFID control items in the aviation field are generally based on metal or composite materials.
Metal-resistant electronic label
In RFID applications, there is no “one size fits all” label, so developing and producing labels for various purposes is the key to solving the problem. Metal objects have a large impact on the performance of UHF tags.
High-capacity electronic label
RFID is used in general fields such as fast cancellation, and the electronic tag memory has 96-bits, which can be expanded to 512 bits of memory. 512bits usually contain 95 characters or 120 digits and are not suitable for mandatory identification standards in the aerospace industry:
Manufacturer CAGE code (MFR);
Product serial number (SER);
Original part number (PNO);
Construction code (UIC);
Parts Description (PDT);
Date of manufacture (DMF);
International Commodity Code (ICC).
4. Application of RFID technology in China's aviation field
In the aviation field, both military aircraft and regional passenger aircraft, domestic large aircraft, have entered a rapid development track. As an effective information technology, RFID technology can help the healthy and rapid development of China's aviation industry. The application of RFID technology in China's aviation field is divided into military and civilian applications according to large industries. On the whole, in terms of the application effect of RFID, civilian use is greater than military use. In the military field, especially in the field of military aircraft production, it is subject to many factors such as confidentiality, and the development is slow, but the demand for RFID applications is urgent.
5. Conclusions and prospects
With the continuous advancement of RFID technology, with the deepening of military-civilian integration, the application cost of RFID technology will gradually decrease, the barriers of RFID application will be less and less, and the application of RFID in the aviation field will be deeper and deeper.
