摘要
飞行试验具有试验强度高,测试参数多,测试、处理、监控与显示实时性高,试飞风险大,技术要求高等特点。如何满足现代技术条件下,对多测试系统之间数据传输的实时性与可靠性,是研究的重点。针对这种要求,专门研制了一套分布式飞行试验测试系统。系统采用分布式双光纤网络体系架构,结合数字视频组播、光传输时间码、NTP网络授时等技术,实现了多测试系统协调、可靠、高效稳定的工作。该系统设计思想对未来武器试验与飞机飞行试验测试系统建设具有借鉴和推广意义。
The flight test has the characteristics of high test intensity,masses of parameters,high real-time performance requirement for testing,processing,monitoring and displaying,and high risk etc.The real-time and reliable data transmission among multiple test systems was studied in this paper.A distributed test system of flight-test was developed for this requirement.The distributed dual-fiber network architecture was used in the system,and the techniques of digital video multicast,timing code of optical transmission,NTP service and so on were used for realizing reliable,highly efficient and stable operation of the system.
