摘要
机载数据链系统是现代民机的重要组成部分,为满足迅速增长的通信需求,机载数据链系统必须具备更快的传输速度和更高的稳定性。基于IMA架构的机载数据链系统是一种新型的数据链系统,各方面的性能尚未得到充分验证。为了验证基于IMA架构数据链系统的时效性,设计并搭建了一套数据链仿真验证系统。该系统包含机载端系统、VHF链路和地面端系统,实验基于ICAO Doc 9896中数据链实际通信性能的测量方法,在地面应用端读取并记录了60条上行报文的发送时间以及收到下行响应报文的时间。结果表明,基于IMA架构的数据链通信系统符合RCP 240性能要求。
The onboard datalink system plays a significant role in civil aircraft systems nowadays.It should be developed to be faster and be equipped with higher stabilities so as to satisfy the increasing demands of communication.The onboard datalink system based on the IMA architecture is a new system and its performance has not been verified adequately.In order to verify the Required Communication Performance of this kind of datalink system,the paper designs and builds a simulation system,which including the onboard system,VHF link and the ground system.The ground system loads and records the time of 60uplink messages and the according response messages based on the methods given in the ICAO Doc 9896.After calculating and analyzing the results,it comes to the conclusion that the datalink communication system based on the IMA architecture meets the RCP requirements.
