摘要
近年来,分布式综合模块化航空电子系统的发展,对航空电子网络提出了更高的要求。时间触发以太网以其特有的优势,可保障数据通信的强实时性,提高网络服务质量,为航空电子网络指明了升级方向。在概括航空电子系统对网络通信要求的基础上,描述常用航空电子网络的特点,指出了时间触发以太网的优势。对时间触发以太网的分析,表明其满足航空电子系统升级要求,是新一代飞机网络技术发展的重要方向。
In recent years,the development of Distributed Integrated Modular Avionics ( DIMA ) brings higher demands on aviation electronic networks.Time Triggered Ethernet( TTE) can guarantee strong real-time communication,improve the quality of network service and indicate the upgrade direction for aerospace electronic networks.In this paper,the requirement of avionics system to network communication is summarized,the characteristics of the avionics network are described,and the advantages of Time Triggered Ethernet are pointed out.The analysis to Time Triggered Ethernet shows that it can satisfy the upgrade of avionics system and is an important direction of the new-generation aircraft network technology in the future.
