Safety management is the fundamental and sustained topic in aviation companies. The proper management of instrument maintaining contributes to the effectiveness and reliability, which ensures the aviation safety and reduces accidents. However, as the scale increasing of aviation companies in recent years, the improper instrument management leads to accidents when maintaining is conducted, which affect the flight safety seriously. Currently manual management cannot meet the safety demand of maintaining instruments since there are huge amount of instruments equipped in the toolbox adopted in the flight maintaining area and there is higher requirement of maintaining places for flights compared with other machines. As a result, there is great need to fulfill the intelligence of toolbox maintaining using scientific techniques. In this paper we develop an intelligent toolbox system based on the RFID and embedded techniques. The system can accurately achieve automatic recognition and management in real time. Moreover, the system has a user friendly interface and can be easily extended for multiple applications. Considering the requirements of the RFID intelligent toolbox, we propose a general framework, which contains the hardware architecture and the software solution. The hardware system includes five modules, which are embedded general controlling module, radio frequency identification module, testing and application interface module, multiple antenna switching circuit module and electrical storage module. Firstly, the S3C6410 processor produced by the SAMSUNG Company is adopted as the embedded main controlling module and the peripheral circuits are developed. In the radio frequency identification module we adopt the super high frequency module SkyeModuleTM M9 supplied by the SkyeTek Company. According to the project requirement the multiple antenna switching circuits are designed. To perform switching, the method of multiple antenna accessing in different time not only can expand the accessing range of the system but also can improve the accessing rate as well as reliability. For the software system, we adopt the bottom to up framework, which contains the establishing of the software development platform, the API designing of communication in radio frequency identification module and the system application program development. The kernel and root files of the Bootloader embedded Linux operation system are executed and transplanted in low level software ...
