【摘要】：机载数据采集系统负责对飞行试验测试数据的采集、传输、处理与存储,是进行飞行测试与试航认证的的关键设备。随着通信网络技术在航空领域中的广泛应用,新型飞机、大型飞机的飞行试验对机载数据采集系统提出了新的要求。网络化机载数据采集系统在扩展性、实时性、数据传输带宽、数据交换与共享等方面均具有较强的优势,符合未来飞机的飞行试验要求。 结合实验室承担的科研课题——“基于实时以太网的数据采集系统关键技术研究、实现与验证”,本文重点研究了网络化机载数据采集系统中嵌入式主站功能模块划分、软件设计与实现。 本文首先对机载数据采集系统的现状与网络发展趋势进行概要介绍,并在对实时以太网EtherCAT详细分析的基础上,提出基于EtherCAT的网络化机载数据采集方案。然后,以嵌入式主站为研究重点,对嵌入式主站进行软硬件功能划分,并详细设计了嵌入式主站软件模块。最后,详细阐述嵌入式主站软件开发流程,构建片上系统并移植Linux操作系统,并对嵌入式主站的邮箱服务进行编程实现与功能验证。
[Abstract]:The on-board data acquisition system is responsible for the acquisition, transmission, processing and storage of flight test data, and is the key equipment for carrying out flight test and pilot certification. With the wide application of the communication network technology in the aviation field, the flight test of the new aircraft and the large-scale aircraft has put forward a new requirement for the on-board data acquisition system. The networked airborne data acquisition system has strong advantages in the aspects of expansibility, real-time performance, data transmission bandwidth, data exchange and sharing, and meets the flight test requirements of the future aircraft. In this paper, the function module division, software design and real-time of the embedded main station in the networked airborne data acquisition system are studied in this paper by combining with the scientific research subject _ "Research, Implementation and Verification of Key Technology of Data Acquisition System Based on Real-time Ethernet". In this paper, the present situation of the airborne data acquisition system and the development trend of the network are briefly introduced, and on the basis of the detailed analysis of the real-time Ethernet EtherCAT, the on-board data collection based on the EtherCAT is put forward. And then, the embedded master station is used as the research focus, the software and hardware functions of the embedded main station are divided, and the embedded master station is designed in detail. And finally, the software development process of the embedded main station is described in detail, an on-chip system is built and a Linux operating system is transplanted, and the mailbox service of the embedded master station is programmed to realize and work.
