飞行试验测试系统由数据采集单元、数据记录单元、数据遥测单元、实时数据处理单元等组成,它是获取试飞数据的重要手段。随着计算机技术、测试技术、信息网络技术的飞速发展,加之新型飞机航空电子环境中海量数据的高速传输对试飞测试系统提出了新的要求,这使得以太网技术开始应用到飞行试验测试系统架构设计中,试飞测试系统向网络化分布式结构发展。网络化试飞测试系统中,需要实时处理的试飞数据量越来越大,因此需要在标准网络传输协议架构下定义一种统一规范的数据格式,用于试飞数据的实时传输与分析处理,满足试飞任务要求。
Flight test system consists of data acquisition unit, data recording unit, data telemetry unit, real-time data processing unit and so on, which is an important means to obtain flight test data. With the rapid development of computer technology, testing technology and information network technology, and the high-speed transmission of massive data in the new aircraft avionics environment, new requirements have been put forward for the test flight test system. This has led to the application of Ethernet technology to the flight test test system architecture In the design, test flight test system to the network distributed structure development. In the networked flight test system, the amount of flight test data to be processed in real time is more and more large. Therefore, a standardized data format needs to be defined under the standard network transport protocol architecture for real-time transmission and analysis of flight test data to meet flight test Mission requirements.
