After pretreatment and data combination, restart algorithm, the mistake after conversion finally can be intelligently provided by scaled data display system
Load value, it is no longer necessary to which personnel carry out the work of conversion overload values, can not only reflect the overload values of real load in real time, also mention significantly
The intelligent level for rising aircraft, meets the requirement of aircraft utilization rate, to improve the intelligent level of flight system, when saving
Between, while also improving the service efficiency of aircraft.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the flow diagram of the embodiment of the present invention.
Specific embodiment
As shown in Figure 1, intelligent conversion method is overloaded in a kind of flight of the present invention, the conversion method includes (1)
It extracts flight status parameter, (2) data prediction, the combination of (3) data, (4) starting algorithm and (5) scaled data to show, specifically
The following steps are included:
(1) flight status parameter is extracted: by overload values, the aero-structure weight value, fuel oil of winged ginseng equipment record needed for conversion
Totally 6 parameters pass through Program extraction and store for weight value and fuel oil position, loads weight value and load-carrying object location；
(2) data prediction: by the winged ginseng equipment extracted record overload Value Data be filtered by program, compress with
And removal cusp processing, and threshold value is set, the threshold value lower than the overload values that aircraft allows 0.4；
(3) data combine: combining the data extracted by same time series；Wherein the time series be with
Undercarriage monitoring system sending pack up signal be 0 as start, undercarriage monitors system sending and puts down signal as terminating；
(4) starting algorithm: combining according to data, combined by the input parameter of program distinguished number with data it is whether consistent, such as
It is inconsistent, it returns and differentiates again, algorithmically convert if consistent；
(5) scaled data is shown: the overload values after conversion show the maximum value in time series by display equipment, wherein described
Overload values are the record numerical value greater than the threshold value as overload Value Data；Staff obtains the overload values after conversion and flies
The overload values that machine allows compare, and decide whether to carry out checking work；If when conversion overload values allow less than or equal to aircraft
Overload values when, can continue to fly, without carrying out any ground check work；If the overload values that convert are more than what aircraft allowed
When overload values, need to carry out inspection.
Embodiment
The overload values that certain aircraft allows are 5.0, and in certain flight course, overload values scaling step is as follows:
(1) extract state parameter: after aircraft is driven, the winged ginseng equipment start recording data on aircraft are when undercarriage monitors
System sending is packed up signal and is started, and program starts to extract overload values, the aero-structure weight value, fuel weight value for flying ginseng equipment record
With this 6 parameters of fuel oil position, loads weight value and load-carrying object location, and store on a storage device.
(2) data prediction: the overload Value Data that the winged ginseng equipment extracted records is filtered by program, is pressed
Contracting and removal cusp processing, set threshold value are 5.0-4.0=4.6, that is, retain the record higher than 4.6 and overload Value Data.
(3) data combine: by treated fly ginseng equipment record overload Value Data on the basis of, by same time series by
The data extracted are combined, and each parameter at each moment is combined as a data.
(4) starting algorithm: combining according to data, combined by program distinguished number required input parameter with data whether one
It causes, as inconsistent, differentiates again, algorithmically convert if consistent.Such as the state of a certain moment aircraft in time series
Parameter are as follows: fly overload values ny=5.2, the construction weight M=1000kg, oil mass Moil=100L, oily position of centre of gravity of ginseng equipment record
Position is L1=300mm aboard for Loil=25mm, loads weight M1=25kg, loads；By algorithm required input parameter with
Data combination is differentiated that the parameter as needed for algorithm 1 is oil mass Moil in 50 ± 15 ranges, construction weight M；Ginseng needed for algorithm 2
It in 100 ± 15 ranges, construction weight M, loads is M1 and L1 that number, which is oil mass Moil,；Program operation contrasts ginseng needed for algorithm 2
