Software Design And Implementation Of A Flight Data Recorder

Flight parameter recording system(Flight Data Recorder or FDR,known as "black box"),is one of the international civil aviation mandatory equipment,widely used in cargo aircraft,passenger planes,helicopters,fighter jets and certain unmanned aerial vehicle(uav),the main purpose is that tracing aviation accident,recording all of the flight parameters between the static start of plane and aircraft landing.These parameters is not only the important basis of the accident analysis,but also the important date support of aerospace vehicles in daily maintenance.In addition to be used for evaluate level of the pilot,the overall performance of verification and provided a reference for the design of new models,these flight data analysis results can also,at the same time,it can also be used to guide and improve flight training skills,etc.After the flight test,the raw data recorded by the flight parameter recording system was analyzed and processed through gigabit et al.To assess the health of aircraft.Since the role of the flight reference system is not limited to accident analysis,the design of the flight reference system is also varied and complex.In this paper,with a certain type of flight parameter recording system software design as the main line,tells the main design idea in the design of flight parameter recorder,and connecting with the 1553 B bus,NANDFLASH module,gigabit network interface design process to do detailed analysis of several important modules.The subject to the actual engineering project as the subject matter,tells the story of a flight parameter recording system software design and implementation process,at the same time,this paper briefly introduces the system hardware design,highlighting the design of software and hardware resources that match the design thought,has good engineering reference.
