S5.2: data packet maximum number of sampling points is calculated；
S5.3: it is successively read one second data flow of data APMB package；
S5.4: judge whether data packet time stamp is equal to record lapse of time；
S5.5: judging result is yes in step S5.4, then resolves one second data and engineering value file is written；
Judging result is no in step S5.4, then fills one second invalid value and file is written；
S5.6: judging whether data packet reads completion,
Judging result be it is yes, then read completion；
Judging result be it is no, then repeatedly step S5.3-S5.5 until judging result be it is yes, read completion.
Another object of the present invention is to a kind of helicopter flight data processing platform framework, the platform architecture include with
Lower module: data processing module, functional module and system management module；

Fig. 2 is that packet adopts flight data processing and is converted into frame and adopts implementation flow chart.
Fig. 3 is paralell composition.
Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing,
It is as shown in Figure 1 the flow diagram of helicopter flight data universal process method provided by the invention, including such as
Lower step:
S1: original flight data file is read；
S2: identification type machine information；
S3: corresponding type decoding dynamic base is called；
S4: judging whether machine configuration information is associated with, and association then carries out next step, is not associated with, and is matched using type standard
Next step is carried out again after confidence breath；
S5: data decoding generates engineering value file；
S6: function selection.
It is illustrated in figure 2 packet and adopts flight data processing and be converted into frame and adopt data flowchart
S5.1: flight data configuration file is read, each packet information, including package identification, data packet name are obtained
Claim etc.；
S5.2: original flight data is split according to package identification, generates several data APMB packages；
S5.3: it is calculated according to the time scale information (being accurate to millisecond) of each data packet head in each data APMB package each
Data packet flight data one second maximum number of sampling points；
S5.4: it reads and flies the resolving configuration of ginseng parameter ground, obtain all winged ginseng parameter informations, including parameter name, parameter
Corresponding data packet mark, parameter restore mode；
S5.5: the reference order in configuration is resolved according to winged ginseng parameter ground, with one second for minimum unit, successively from tearing open
It is engineering value write-in engineering value file that the data APMB package divided, which extracts the identical flight data of markers seconds value and resolves, if some
Data packet was then filled with specified invalid value at a certain second without data, if some data packet was in a certain second sampled point
Number is less than its maximum number of sampling points and then uses interpolation method polishing sampled point；
S5.6: repeating step S5.5, finishes until the data APMB package of all fractionations is all read.
After being parsed to flight data according to data packet, parameter is decoded, forms engineering value file.Flying quality
