Test flight data file automatic distribution method

Abstract

The invention discloses a test flight data file automatic distribution method, and aims to search a more effective test flight data file distribution realization scheme, and the method comprises the following steps: obtaining a test flight sortie report based on a test flight sortie and a test point; reading a test flight data file according to the test flight frame number; confirming a test flight subject through the test point number, and searching a test parameter list in a test flight outline database corresponding to the test flight subject; and intercepting the test flight data file by using the test parameter list, the test point execution starting time and the test point execution ending time to obtain intercepted test flight data, packaging the intercepted test flight data, and storing the packaged test flight data in a test flight subpackage result cache database. Through the associated test flight data, test flight sortie report and test flight outline, the sub-packaging andunpackaging processes of all test flight data are realized at the server side, so that a large amount of useless data is filtered before distribution, and the communication efficiency is improved.

Description

technical field [0001] The invention relates to the communication field, in particular, the invention relates to a method for automatically distributing flight test data files. Background technique [0002] The flight test of civil aircraft will generate a large amount of flight test data, which is of great significance to the design and manufacture of aircraft, airworthiness certification and other aspects. Therefore, after the flight test is over, engineers and technicians of all relevant professions hope to get the data files as soon as possible, so as to quickly carry out the analysis of the flight test data. The flight test data file usually consists of a huge two-dimensional table, each column in the table represents each sensor on the test machine, and the row in the table represents a data collection with the time of data collection at the head of the row. If the data collection frequency is 16 Hz, 16 rows of data will be generated every second, and 115,200 rows of ...

Problems solved by technology

[0007] 3. Flight tests are usually carried out in the field and distributed all over the world. The network environment is relatively poor and unstable. It takes too long for the transmission of a large amount of flight test data, and it is often affected by the stability of the network. Unable to transmit normally;

[0008] 4. All data files transmitted in the network have not been split, and the file size is huge, which puts great pressure on the transmission, storage and calculation of data files
