Embodiment 1

[0030] An embodiment of the present disclosure provides a platform architecture method for synchronous playback of multi-type flight parameter data, including the following steps:

[0031] Step 1, according to the data structure of each type of flight parameter data, establish the index information of each type of flight parameter data file;

[0032] Step 2. Initialize the data management thread and display window of the flight parameter data file according to the index information;

[0033] Step 3. After the data management thread is initialized and relocated, read the data from the flight parameter data file corresponding to the index information, and place it in the playback buffer after decoding;

[0034] Step 4. The display windows of several flight parameter data files are distributed in the main window, and the flight parameter data information is read and displayed from the play cache corresponding to the flight parameter data files in real time.

[0035] The synchron...

Abstract

The embodiment of the invention provides a synchronous playback platform architecture method for multiple types of flight parameter data, and relates to a flight parameter data processing technology,which comprises the following steps: step 1, establishing index information of various types of flight parameter data files according to data structures of various types of flight parameter data; step2, initializing data management threads and display windows of the flight parameter data files according to the index information; step 3, after the data management threads are initialized and repositioned, reading data from the flight parameter data files corresponding to the index information, and placing the data in a playing cache after being decoded; and step 4, distributing the display windows of the plurality of flight parameter data files in main windows, and synchronously reading and displaying the flight parameter data information from the playing cache corresponding to the flight parameter data files in real time. According to the synchronous playback platform architecture method for the multi-type flight parameter data, a universal design is adopted, playback of various typesof data can be carried out in the same main window, the operation convenience is improved, and the interpretation efficiency is improved.

Description

technical field [0001] The disclosure belongs to the field of avionics, relates to a processing technology of flight parameter data, and in particular relates to a synchronous playback platform architecture method of multi-type flight parameter data. Background technique [0002] With the development of avionics, aircraft record more and more data, and the types of data packets are more and more complex. Among them, the flight parameter data is collected and recorded by the flight parameter recording system, which plays an irreplaceable important role in the investigation of aviation accidents. [0003] At present, there are many types of flight parameter data collected by aircraft. If the various types of flight parameter data are played back one by one, it will seriously affect the interpretation efficiency of flight parameter data and seriously reduce the processing effect of flight parameter data. [0004] Therefore, it is necessary to design a method capable of synchro...
