摘　　要：航空电子系统是民航客机的重要组成部分,远程数据集中器对航电系统数据的处理和转发起到至关重要的作用。文中设计的远程数据集中器基于PowerPC架构VxWorks平台,通过编写程序和配置板级支持包,完成远程数据集中器的设计。主要功能是对航电系统中的AFDX总线数据、ARINC429总线数据和离散量实现相互转换。首先,对VxWorks系统、MPC8270硬件平台和航空总线数据进行研究;其次,搭建远程数据集中器设计框架,并进行模块化设计与实现;最后,对设计的远程数据集中器进行测试,完成预期功能。The avionics system is an important constituent part of the civil aviation passenger aircraft,and the remote data concentrator plays a crucial role in data processing and forwarding of the avionics system. Therefore,a remote data concentrator based on the PowerPC architecture and VxWorks platform is designed in this paper. The design of the remote data concentrator is completed by compiling the program and configuring the board-level support package. The main function of the remote data concentrator is to realize mutual conversions among AFDX bus data,ARINC429 bus data and discrete quantity of the avionics system. The VxWorks system,MPC8270 hardware platform and aviation bus data are studied. The design framework of the remote data concentrator is built,so as to conduct the modular design and implementation of the remote data concentrator. The designed remote data concentrator is tested to complete the intended functions.
