基于3G通信网机载飞行记录数据无线传输系统设计

Design of an airborne wireless transmission system for the data of airborne FDR based on 3G networks

为了对机载飞行纪录数据实现无线传输,提出了基于3G通信网实现机载飞行记录数据的无线传输,此系统实现了对机载飞行纪录数据的读取、加密和无线传输。此系统克服了工作人员前往停机坪用有线方式下载数据或用转存设备方式获取数据的方法,当飞机出勤率高或者飞机架数多时,极大地提高了工作效率和降低了机场保障成本。

To achieve transmitting the data from airborne FDR by wireless communication,the design of the wireless transmission system based on 3G networks is described in this paper.The wireless transmission system can read,encrypt and transmit the data of airborne FDR by wireless form.Now maintenance personnel have to go to parking apron for downloading the data of airborne FDR by wired form or taking down the memory device of the airborne FDR,the wireless transmission system can replace the traditional form and dose it well When high attendance rate and large number of the aircraft comes to use the wireless transmission system can improve work efficiency and lower the maintenance.
