Both aviation maintenance and air material management cannot use traditional methods for a long time. It is necessary to constantly search for new technologies to complete daily work, so as to ensure that China's aviation industry is steadily improved. From the existing work, RFID technology is an important technology that is currently highly respected.
Simply put, RFID technology is mainly radio frequency identification, which is a prominent communication technology. In practical applications, by using RFID technology, it is possible to use radio signals to better identify specific targets and to accurately read and write related data without establishing mechanical contact in identifying systems and specific targets. There is no need to establish the basis of optics. From the perspective of technology itself, the advantages of RFID technology are more:
(1) The operation of RFID technology is relatively simple. It bids farewell to the complicated control in the past. It only needs to perform flexible and automatic control according to the objective requirements. The work efficiency and work quality are worthy of recognition.
(2) Using RFID technology, data can be read more quickly. In the test process, the effective recognition distance of RFID technology has exceeded 30m, which is a very suitable technology for aviation maintenance and material management;
(3) RFID technology achieves good dynamic real-time communication. In operation, the technology enables tags to communicate with the reader at a frequency of 50 to 100 times per second. It can be seen that RFID technology has strong feasibility for practical work.
3 RFID technology in aviation maintenance, aircraft management
With the passage of time and the development of society, China's aviation industry has achieved unprecedented improvement, but still have to solve more problems in aviation maintenance and aviation material management. RFID technology has achieved great success in theory, and its own technicality is relatively strong, but how to ensure that RFID technology can have an ideal effect on aviation maintenance and aviation material management is very worthy of study.
3.1 System software design
In order to improve the work level of aviation maintenance and aviation material management in essence, it is absolutely impossible to carry out the work according to the previous experience. It is necessary to complete the maintenance work and management work on a large amount of realistic data. RFID technology has shown outstanding levels in many aspects. At this time, we can use RFID technology as the basis to design software that conforms to aviation maintenance and air material management, so as to improve work efficiency and work quality, even in the face of a large number of Work can also be handled with ease. Combining the previous work experience and current working standards, the author believes that the design of system software needs to proceed from the following two aspects:
3.1.1 Software development tools. After comprehensive comparison and analysis, it is recommended to use ASP.NET to complete the software development tool selection. ASP.NET is launched by Microsoft Corporation. Its predecessor is ASP. It inherits the advantages of ASP, and has improved its shortcomings. It is powerful and can support many languages, such as C++, C#, VB, etc. Because C# is commonly used, it is A language designed specifically for ASP.NET, ASP.NET pages consist of tags and code files. Compiling the code is more classic. The parsing code in ASP has more advantages. In order to take advantage of these advantages, the markup must also be compiled. The compilation process involves two main steps:
(1) Convert the markup to a C# suitable for the ASP.NET class hierarchy;
(2) Compile the temporary into an assembly, and then load the resulting assembly into the application domain hosting the application.
3.1.2 Module design of aviation maintenance and aviation material management system functions based on RFID technology. In the design process of RFID-based systems, the module aspect is a specific implementation part, which is directly related to whether aviation maintenance and aviation material management will be realistic. This paper believes that the module design includes the following three aspects:
(1) The data management system of RFID technology, which is mainly composed of a central database and a terminal manager, so as to realize the overall control of the system;
(2) Aviation material management information system, which is mainly to realize the effective management of aviation materials, and complete the management level of aviation materials through the analysis of market conditions, the actual demand of aviation work, the daily stocking volume and the financial situation. Increase, avoid creating a vicious circle of aviation material management;
(3) Maintenance engineering system. Aviation maintenance is not a simple maintenance. In addition to handling maintenance problems, the system also implements the filing of past problems, the analysis of classic cases, and the analysis of special situations. On the one hand, avoiding the repeated occurrence of maintenance problems, on the other hand, Provide more reference and guidance for the future aviation maintenance optimization, and achieve continuous improvement of maintenance level.
3.2 Process design of RFID technology applied to aviation material management
Today, with the rapid development of aviation industry, the process design of aviation material management must be as simple as possible, and it should not cause too complicated situation. Otherwise, it will easily fall into the past problems, and the losses caused by it will be relatively large. At present, RFID technology is a prominent technology. By applying this technology to the process design of aviation material management, it has achieved outstanding results. In the current process design, the application of RFID technology is mainly done from the following three tasks:
3.2.1 Storage. Before the new materials are put into storage, they should be numbered according to the type of materials and related information, and the RFID tags are written by the terminal manager. The generated electronic tag data is transmitted to the central database to serve other modules.
3.2.2 Air material replenishment. Position adjustment in the system: Since the warehouse is not always unchanged, sometimes it is adjusted according to the demand, some have to be moved into the position, some have to move out of the position, and the administrator downloads the corresponding instruction in the RFID system operation through the handheld terminal.
3.2.3 Air material inquiry and delivery. When inquiring about the relevant materials, the administrator first checks the catalogue number of the aviation material through the query management subsystem, and the system extracts the corresponding data information by the number of the aviation material, and issues the delivery instruction after the proofreading is consistent, when the aircraft passes the exit port. At the time, the RFID reader at the exit port feeds the reading material information back to the management center in real time, and the manager reconfirms whether the actually required aircraft material is consistent with the outbound container material. At this point, the system records the outbound time information and personnel of the aircraft.
