1.引言作为先进航空电子系统的重要子系统—数据传输设备有二个主要的组成部分:机载的数据传输设备和相应的地面支援站。数据传输设备为航空电子系统正常工作提供必要的任务数据;实现飞行员和航空电子系统之间、非航空电子设备和航空电子系统之间的数据传输和记录。它为飞行任务的执行、飞行情况的分析、飞机的地面维护提供十分重要的手段。为此,数据传输设备需要
1. INTRODUCTION As an important subsystem of advanced avionics system - Data transmission equipment has two main components: airborne data transmission equipment and corresponding ground support station. Data transmission equipment provides the necessary mission data for the normal operation of avionics systems; data transmission and recording between pilots and avionics systems, non-avionics and avionics systems. It provides a very important means for the implementation of the mission, the analysis of the flight situation and the maintenance of the ground of the aircraft. For this purpose, the data transmission equipment needs
