The data processing module is used for pre-analyzing original data to be uploaded by a user, uploading effective files to a server side and simultaneously removing ineffective files; taking the cesna 172R model airplane as an example, the GARMIN1000 system has two display screens, PFD and MFD, in the cockpit. The PFD is mainly used for displaying airplane attitude and navigation data, and the MFD is mainly used for displaying all parameters of an engine, a chart, an electronic checklist and the like. To the right of each display are two slots for the SD card, with the upper slot for the MFD for storing electronic checklists. The SD card of the MFD upper slot may also be used to store flight data when the GARMIN1000 system software is upgraded to version 563.26. The GARMIN1000 system begins recording flight data when the aircraft electronics overhead gate is turned on. The time interval for data recording is one second, and the recorded data includes most of the navigation data and all of the engine data. When the airplane closes the main electric door of the electronic equipment, the data recording function is immediately stopped. The crew member takes off the SD card on the top of the MFD, connects the SD card to the computer by using a common card reader, searches the data _ log folder under the root directory of the SD card, and stores the flight data of all time periods in the folder. The data of each time interval is a single file, and the file name is the time.

Mechanical faults with certain probability exist in the operation process of the comprehensive avionics system of the airplane, so that part of invalid files are generated, and the judgment conditions of the invalid files comprise: files smaller than 50KB, files with key data continuously blank and too long, files with names not conforming to the system format, errors in the format of data in the files and the like. After the user uploads the original data file, the data processing module conducts preliminary invalid file screening through pre-analysis (the invalid file condition is as described above), and the valid file is uploaded to the server to be analyzed. A user with high authority can mount a self-defined analysis engine to be added into an analysis queue for analysis, and an analysis result enters a data analysis module for further reference.
The data analysis module is used for displaying the analysis result of the effective file, and the analysis result comprises the analyzed out-of-limit event and/or red mark event; and because some events have important investigation value, only concern about the situation that the aircraft data can not record the event completely, so can according to the actual situation, to some single overrun event supplement necessary relevant investigation information of flight, the concrete operation is: after a certain event is selected on a client event viewing page, filling related information, such as flight properties (including single flight, take flight, captain training, new teacher take flight, task flight, practice examination and the like), event related personnel and the like, in a supplementary interface at the lower right corner, storing and uploading the information to a server, and completing information supplement.
