摘 要: | 先进分布式综合飞行器管理系统对通信网络的实时性和确定性有严格要求。研究了时间触发以太网(TTE)的同步服务、提出了在符合ARINC653标准的分区操作系统下,基于TTE网络的分布式系统分区同步方法,建立分区同步测试平台,并对分区同步精度进行测试分析。测试结果表明,基于TTE网络的分布式系统分区同步的精度和抖动均可达到μs级,可满足先进分布式综合飞行器管理系统的网络时间同步的要求。

Abstract: | Advanced distributed integrated vehicle management system has strict demands on real- time and determinism for communication network. We studied the synchronization services of Time Triggered Ethernet(TTE) ,presented a method of distributed system partition synchronization based on rITE, which the partition OS conforms to ARINC653 standard, built a test platform for partition synchronization, then the precision of partition synchronization was tested and analyzed. The results of precision and jitter of dis- tributed system partition synchronization based on TTE meets the demands on synchronization for commu- nication network of advanced distributed integrated vehicle management system. |
