Embodiment

[0156] A device for quickly extracting key parameters of large-flow network data is provided, which is composed of a data interface module, a data processing module and a data storage module. Realize the real-time collection, unpacking, calibration, calculation, grouping and storage of airborne network data streams. The system framework is as follows: figure 1 shown. Before the test flight, the ground support equipment defines key parameters and configures the format. During the flight test, the data interface module receives the network data flow of the onboard acquisition system, and the data processing module completes the unpacking of the network data flow, and performs real-time data processing, including parameter positioning, splicing, engineering quantity conversion, etc., and finally transmits it to the data center. Real-time storage is carried out in the storage module. After the test flight, the ground support equipment can directly read the stored data for data an...

Abstract

The invention provides rapid extraction equipment for data key parameters of a large-flow network. The rapid extraction equipment is composed of a key parameter rapid processing unit, namely a data processing module, a ground computer, parameter configuration and data processing software, a cable, an accessory and the like. Real-time acquisition, unpacking, calibration, calculation, grouping, storage and data processing of airborne network data streams are realized. According to the invention, data with ultra-large network capacity can be obtained; the preprocessing operation of all network data packets can be completed in an extremely short time; available data packets are classified, and unavailable data packets are discarded; according to the method, the network burden of big data transmission on subsequent data processing equipment is relieved, meanwhile, due to the real-time performance of data preprocessing, data packet loss caused by accumulation of network data is avoided, flight data loss caused by accumulation of the network data is avoided, and the integrity of the data and the rapidity of parameter extraction are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of data extraction, and in particular relates to an extraction device for large-flow network data parameters. Background technique [0002] Civilian large aircraft is a typical complex product system with high knowledge content and a wide range of technical fields involving mathematics, aerodynamics, materials science and other disciplines and the fusion of various technologies. Aircraft test flight is a necessary means for the aircraft to carry out experimental flight before formal use, to check the equipment of the aircraft and to verify the performance of the aircraft. The technical content of the flight test of large civil aircraft is very high, and it is necessary to have a large number of test equipment to test various parameters of the aircraft. Generally, more than 20,000 test parameters need to be recorded for an aircraft, and more than 5,000 need to be monitored in real time. , and there are only ...
