时间触发以太网在航空电子系统中的应用

摘要

首先，介绍了分布式综合模块化航空电子系统（ DIMA）的架构，然后，分析了时间触发以太网（ TTE）的特性，最后，针对DIMA架构下的TTE的通信调度问题，提出了基于TTE组循环周期、TT消息调度表周期和剩余时间的调度方法，并对生成的通信调度表进行了分析和评价。%The framework of distributed integrated modular avionics ( DIMA) is introduced at first.Then the characteristics of Time-Triggered Ethernet ( TTE ) are described.Considering the TTE's communication scheduling problem in DIMA architecture,a scheduling method is presented based on TTE cluster cycle,period of TT message scheduling table and remaining time,and analysis is made to the generated TTE communication scheduling table.
