Embodiment
[0050]In order to facilitate understanding of the content of the present invention, the flight data is first described below.
[0051]The general aircraft avionics system mainly includes the main flight display PFD, multi-function display MFD, integrated processor IPC, various sensor devices. The flight data acquired by various sensor equipment can be 4 categories: 1 is the basic information class data, 2 is the flight status class data, 3 is the aircraft system class data, 4 is the engine system class data, including the cockpit various types of manipulation Quantity (record driving rod / disk, throttle position, various types of switches, etc.), flight state (air speed, welcome angle, side slip angle, pitch / roll / yaw posture, spatial location, etc.), engine state (speed) , Fuel flow, oil flow / pressure / temperature, etc.), flight management and automatic flight system status (current flight mode, performance and navigation parameters), etc.
[0052]The various sensors mentioned abo...

[0142]The ground waiting phase, the ground waited timeout super-limit event level determination, based on GNDSPD (vertical speed) RPM (engine speed), the overlinked level is classified 3, of which level 1 includes: lasting 15 min; wherein Level 2 includes: lasting 20 min; Level 3 includes: lasting 30 min.
[0143]In the ground waiting phase, the level determination of the unfinished heater test is over-limit event, based on OILT, RPM, the over-limit level is only one level, which is directly 3, triggering is a super-limit event.
[0144]The ground-slip stage, the line sliding speed overrun event level determination, based on GNDSPD, over-limit level is classified 3, of which level 1 includes: gndspd>30,>5s; 2nd levels include: gndspd>30,>10s; three of them include: gndspd>30,>15S.
[0145]In the air stage, the level determination of the pitch gesture overrun event is determined, based on PITCH (pitch angle), the over-limit level is classified 3, of which level 1 includes: if Pitch>18 °, last...

Abstract
The invention discloses an aviationflight datavisualizationprocessingsystem and analysis method based on data cleaning, and the system comprises a program control module for processingflight data, a user setting module, a data preprocessing module, a data analysis module, and a data display module. The program control module starts the user setting module and the data preprocessing module, and the flight data processed by the data preprocessing module is analyzed by the data analysis module and then displayed by the data display module. By means of the scheme, fusion analysis is conducted on the multi-dimensional data of the flight data, and therefore the purposes of visually and visually displaying historical data and evaluating and early warning possible events are achieved, and high practical value and promotional value are achieved.
Description
Technical field[0001]The present invention belongs to the processing and analysis of aviation flight data. Specifically, it is to address the visualization processing system and analysis method of air flight data based on data cleaning.Background technique[0002]Flight quality monitoring is a system that collects and analyzes daily flight data. It is one of the internationally recognized means of guaranteeing flight safety. It has been widely used in civil aviation. In response to general aviation, due to models, extensive operation, extensive operation, unable to specify hard requirements, etc., universally not installed flight data recorders, and its flight quality and operational risk have not lacked effective monitoring tools and analysis tools.[0003]By introducing a flight data recording card (SD card) in a general aviation aircraft, the flight critical information and engine data can be recorded, considering that the vast majority of data recorded in the SD card is synchronized...
