Development of aircraft Gigabit Network Data Recorder

摘要:

为了满足对新一代网络化机载测试系统输出的海量高速网络化测试数据记录的需要,设计并实现了一种基于COMe主控模块和工业级通用固态硬盘的机载千兆网络数据记录器;该记录器使用集成有英特尔处理器、板载DDR3内存和FLASH存储器的COMe主控模块,可进行IRIGB-AC时间码授时的底板和作为数据存贮介质的固态硬盘构成硬件系统平台,并采用Linux嵌入式操作系统和优化的数据存贮算法程序,完成了一路千兆机载测试网络数据流的接收、打包和记录;试验室和飞机上大量实验结果表明该记录器工作性能稳定,无误码和丢包现象,可以大量应用在使用环境复杂的飞机网络化机载测试系统中。

Abstract:

In order to meet the requirement of high-speed and high-capacity network data recorder for new network Airborne test system, this paper developed a gigabit network data recorder based on COMe module and SSD. The COMe module which had an Intel processor,DDR3 chipsets and FLASH ,Solid State Disk and Motherboard integrated system hardware platform that used Linux embedded operating system. Application tests and experiments show that the recorder is high degree of reliability, no bit error ,no packet loss and wide application aircraft network test system. 
