With the further development and practical application of the airport, all aspects of the airport’s work can present a better, faster and safer situation.
System background
In recent years, the air transport service industry has continued to expand rapidly. Airports in various regions are also trying to improve work efficiency in order to provide as fast as possible services. However, under general conditions, it is necessary to facilitate the daily operation of hundreds of aircraft and a large number of passengers. Providing satisfactory services in terms of safety and security is not an easy task, at least much more difficult than the phenomenon observed by ordinary passengers around the airport. Thousands of luggage lockers belonging to different airlines, hundreds of transport vehicles, trolleys, and other devices that frequently move back and forth from various areas are distributed in some large-scale international airports in China. To make these objects run smoothly, the airport needs to design an efficient and sophisticated planning and logistics system, and rely on a large amount of manpower, material resources and specialized equipment to make it run smoothly and orderly. However, even with careful human arrangements, special transportation vehicles and suitcases are often misplaced or lost. Additional manpower is required to find the RFID technology in the airport logistics real-time positioning system to analyze these assets or provide a written report to them. Managers to coordinate the use of resources in all aspects. Of course, if the coordination here is not smooth, it will cause more misplacement and loss events, and even fall into a vicious circle, which is extremely detrimental to the airport management authority. Looking at the experience of airport logistics management at home and abroad, for any intelligent system (technology) that wants to solve the above problems, the following four functions are indispensable:
1. It is very convenient to find luggage lockers and transportation equipment;
2. Any delay in finding important assets for flight preparation purposes can be eliminated in time;
3. Avoid the extra burden of manual search;
4. It can remotely control related logistics.
Facing the complicated airport logistics situation, a real-time positioning system based on active RFID technology was produced. This system can track and locate the cargo at the airport in real time, making the flow of goods orderly and checkable. This technology can greatly improve the management level of cargo. , And can bring revolutionary changes to the work of airport managers.
Introduction to System Technology Principles
The real-time positioning system based on active RFID technology provides airport managers with an intelligent tool that can effectively monitor the flow of goods and improve the level of cargo management. This system is a typical application of Internet of Things technology in airport logistics. The grid positioning system composed of long-distance readers can easily determine the regional location of the cargo and obtain real-time information of the cargo. The back-end can also output all the cargo lists and trend reports in the airport in real time, and cooperate with the management of the handheld machine. Deduct the management of airport logistics incisively and vividly.
Scheme structure and composition
The application of this system is shown in Figure 1. It consists of an electronic tag installed on the goods, a positioning card reader and a monitoring computer. The electronic tag installed on the object continuously emits signals, and the positioning card reader installed next to it reads Take the signal sent by the idea tag, upload it to the monitoring computer via GPRS, and analyze the location of the goods through the computer software; additionally equipped with a handheld machine, which is convenient for the staff to carry, when the staff carries the handheld machine through the goods, the handheld machine can be used Scan the relevant information such as what goods are next to you and the destination you want to go to, which is convenient for the staff to manage.

System functions
The key to solving the problem of large-volume airport logistics is to accurately grasp the location of personnel and equipment at each time node. In this system, the core devices are ML-M5000 series readers, ML-M4001 handheld card readers and ML-65 series active tags: long-distance readers can simultaneously identify 200 moving target objects in the same airport Or use the Internet to exchange data at high speed and real-time between various airports and the background to solve the problem of remote control of personnel and assets; low-cost active tags can be attached to target personnel and assets to achieve control of parcel boxes, special transportation vehicles or equipment Unique identification. The background software realizes the status recognition of any cargo, including the recording, analysis and report of its movement route. Customers can also customize resource management software with different functions and sizes according to their actual positioning and control requirements, so that the entire system can better meet the actual conditions of airports in various regions.

Practical application of the system
Solve the problem of missing luggage
Install RFID tags on luggage at the airport check-in counter (need to be associated with passenger identity), and install readers at the counter, luggage conveyor belt, and cargo hold. In this way, the system can track the baggage all the way until the baggage reaches the passenger’s hand. Solve the problem of missing luggage in the past. If the passenger cannot find the corresponding baggage, he can trace back the baggage circulation process through this system to quickly find the corresponding location.
Warehouse management of goods
RFID technology can make electronic tags on the cargo boxes to record the placement, product category, date, etc.; and through the electronic tags on the items, you can know the status, location, and status of the goods at any time according to the unique code of each product. There is a place where it is lost or delivered to facilitate storage management. Especially for some dangerous goods, there are some special regulations for its handling, loading and unloading and storage, and a little carelessness may cause serious consequences. In some specific areas, such as densely populated areas, once the reader finds that a cargo box containing dangerous goods has entered, it will immediately trigger an alarm message.
Transportation process and cargo tracking
The system can record and track product operation in real time, accurately and completely, and can comprehensively and efficiently strengthen the management of product production, transportation, and sales, and provide various comprehensive and easy-to-use functions such as query, statistics, and data analysis. . Each cargo can be set up with complete information inside the network, and the contents, routes and logs of cargo tracking and management can be clear at a glance.
Minimize the accident risk of the aircraft as much as possible
First of all, it can reduce the risk of aircraft maintenance errors. In the huge aircraft maintenance warehouse, professionally trained senior mechanics spend a lot of time checking logs every day to find suitable parts on the aircraft. They use this inefficient way to find The method of repairing parts will not only make mistakes frequently, but also waste a lot of precious time. The use of electronic tags on important parts of the aircraft can quickly and accurately display the relevant information of the parts, helping the airlines to replace the problematic parts more quickly and accurately, thus saving a lot of manpower and material resources.
Tracking and positioning of goods and personnel
After the application of RFID technology, it can correctly indicate the specific location of each goods among a wide range of goods. And can point out the specific location of the relevant person to be looked for in the airport or on the plane. The purpose of the network system is to improve the safety of the job site. The specific measures are as follows: Only drivers who have been trained and approved by the management department are allowed to drive into the job site; the site is equipped with an electronic verification device that can be checked at any time. Another purpose of the network system design is to reduce maintenance costs. Vehicle operating condition data can be automatically uploaded, vehicle problems can be reported in real time, and vehicle maintenance plans can be formulated according to the actual use of the vehicle, and no longer scheduled according to a fixed date; It can help the management department to replace the vehicle at the most economical and ideal time; the design purpose of the asset management network is to improve the utilization rate of the vehicle, to ensure that the vehicle appears in the required place at an appropriate time, and to provide the management department with a special report of the vehicle utilization rate, etc. .
Coping with terrorist attacks and security
Through RFID technology, a person on the blacklist can send a warning signal when passing the checkpoint, and immediately indicate the location of the relevant person’s luggage. So that the management staff can find out the luggage in time and accurately do related work, and better prevent the occurrence of terrorist incidents. Each electronic label has a set of independent numbers that cannot be modified and is specially encrypted. Can manage sensors and intrusion detection equipment, such as creating, deleting, modifying sensor properties and moving sensors.
Authorization of the scope of entry and exit for airport employees
The airport can regulate the scope of activities of each staff member according to their position and identity, and then place the electronic tags of the above information on the staff’s work card. RFID technology can identify whether the employee has entered an unauthorized area, so as to better manage the employee.
Long-distance location determination
RFID technology can accurately determine the position within a long distance of tens of meters, avoiding the inconvenience of the old technology that can only detect the position in a short distance. It provides convenience for airport personnel when determining the location of objects and personnel.
