At present, in the field of aviation in China, whether it is a military industrial enterprise or a civil aviation enterprise, in the production and manufacturing process, the measuring and management of the production workshop is mostly identified by a lettering or a code plate on a measuring tool, and manual entry of manual information is used to record information. This is where the gauges are tracked, calibrated and recorded. With the improvement of processing efficiency and automation, and the large use of measuring tools, this traditional way of manual tracking of measurement information has been difficult to meet the current production and processing needs of measuring tools. With the popularization and development of Internet of Things technology, RFID technology has become more and more widely used in all walks of life. RFID technology has the advantages of non-contact recognition, large storage capacity of information, convenient and quick access to information and so on. In the production process of aviation companies, the full lifecycle management of the use of measuring tools and the full use of the advantages of RFID technology can greatly save the cost of the production of measuring tools and increase the standardized management of the use of measuring tools in the production process of enterprises. Production and operating efficiency.
Second, the statusqu at home and abroad
With the development of IoT technology in recent years, the main players in the domestic and foreign aviation sectors, such as airlines, aircraft manufacturers and suppliers, have gradually adopted RFID technology to track and identify fixed assets, and have incorporated this technology into trade cooperation. The partner program, the aviation industry maintenance and manufacturing manufacturing process gage management is an important application of maintenance and management of fixed assets. International aviation giants like Airbus and Boeing still have many technical difficulties in practical project applications, such as the installation of radio frequency identification tags and how software solutions are compatible with international standards.
At present, in the field of aviation in China, whether it is a military industrial enterprise or a civil aviation enterprise, RFID technology is still not widely used in gage management. On the one hand, due to the imperfect development of RFID technology-related standards, RFID technology is applied in the aviation industry in China. The promotion has brought certain difficulties; on the other hand, the system stability, product reliability, and information security of RFID technology applications have not been fully guaranteed, and RFID technology has not been widely implemented in China's aviation industry.
Third, RFID technology advantages
In the measurement process of military aviation industry in China, there are many types and quantities of measuring tools. The use of manual recording and artificial reminding of traditional measuring tools for borrowing and calibration is inefficient and prone to errors. There is no automatic expiration reminder function during the calibration calibration cycle.
The main purpose of gage management based on RFID technology is to collate relevant requirements of existing gage management services such as measuring tool borrowing, gauge calibration information entry and update, gauge calibration cycle overdue reminding, and determine various usage scenarios using RFID technology for measuring tool use and calibration. The implementation of RFID technology under the intelligent management system.
With RFID technology, the following gage management problems will be completely solved:
★ Fast inventory inventory, improve the efficiency of 90%;
★ Analyze the turnaround efficiency of the measuring tool and increase the efficiency;
★ Clearly grasp the real-time status of all measuring tools and can obtain calibration status information;
★ Clear measuring tools borrowed from responsible persons and borrowing cycle management, and the responsibility was implemented to the borrower;
★ Measuring tool life cycle management;
Fourth.Application of RFID in Measuring Tools in Aviation
RFID gage management involves procurement department, measurement and calibration department, measurement warehouse, and production workshop. The scope of business includes: initial calibration of measuring tools, asset registration, borrowing and withdrawal of measuring tools, borrowing and retrieving of measuring tools, calibrated and calibrated delivery of calibration tools, completion of calibration and storage, and decommissioning of measuring tools.
The system design is divided into three layers. The bottom layer is a hardware access layer that can intervene in various hardware, including readers and tags;
The middle layer is data logic management, hardware access configuration, user rights configuration and so on.
The uppermost layer is the application layer, which can access end-user systems such as WMS, MES, etc., or enterprise ERP, and can provide API interfaces.
Anti-metal RFID tags are mainly used to identify each measuring tool. When used, they need to be fixed on each measuring tool. The information of the label is used as the index of the label information, and all the information of the measuring tool can be recorded in the database. After each borrow, return, calibration, and other actions, the information in the tag on the gage is updated by changing the tag information on the gage. Complete the electronic label issuance, store the basic information of the equipment, and realize the one-to-one binding between the electronic label and the equipment.
As shown in the red circle in the above figure, the anti-metal electronic label is strongly glued to the measuring tool to ensure that the label does not fall off during normal use of the measuring tool. Precautions:
1, to meet the application requirements in acidic, alkaline, oil, high temperature and high humidity environment.
2, to meet the application requirements in the metal surface.
Fifth. RFID Technology Application Suggestions
With the popularization and development of Internet of Things technology, RFID technology will gradually be promoted and used in the aviation field in China. During the application of RFID technology, we should pay attention to the details of some technical applications. First, we should do a good job in the prototype design of visualization software to ensure the stability and reliability of the system during the application of RFID technology; second is to further test the consistency of reader-resistant metal labels. And stability; Third, do a good job of anti-metal label selection and installation work, to ensure that the label on the metal surface adhesive firm, beautiful.
