With the increasing amount of flight test data, the traditional single-thread technology has been unable to meet the needs of rapid processing of massive flight test data. In order to improve the efficiency of flight test data processing, the characteristics of flight test data processing are analyzed, and a parallel flight test data processing method is proposed. This method realizes two-level parallel processing of multi-link parallel and data frame analysis parallel of flight test data. The method is verified by actual data, and the results show that the efficiency of this method is significantly improved compared with the traditional single-thread data processing method.

With the rapid development of aviation electromechanical technology, new aircraft are equipped with a large number of sensors and electronic control devices. In order to meet the data transmission requirements of avionics systems, Ethernet Data Distribution (DDS) protocol has gradually become the standard solution for published/subscribed data in distributed real-time systems. Facing the new requirements of bus data processing using DDS protocol, starting from the characteristics and format of Ethernet DDS data recording, this paper gives the overall architecture and core processing method of the processing software. This paper analyzes the key problems of Ethernet DDS data processing and proposes solutions for DDS bus Interface Control Document (ICD) plane structure, multi-level parallel data processing algorithm, data detection and filtering. The method is validated and can correctly process Ethernet DDS data.
