[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.
