Description
Technical field
The present invention relates to radio monitoring technical field, the storage of specifically a kind of frequency spectrum data based on bitmap, which shows, is
System and method.
Background technique
In radio monitoring technology, can often be related to will be in document or report to the graphical representation of frequency spectrum data, this
Spectrogram in this document passes through the operation screenshot to graphical frequency spectrum control in monitoring or analysis software.These screenshots
Initial data and the software of pairing is needed to carry out authenticity and verification of correctness.It is clear that the separation of screenshot and data, makes
It must verify and need cost.The Aspect Ratio of stretching, the display of the presentation mode, control of UI, screenshot regional location etc. all can be at
To influence the factor of screenshot to make bitmap change.
Present spectrogram screenshot, in addition to carrying screenshot or third party's screenshot tool interception correlation by operating system by hand
Outside the interface of software, mainly pass through the screenshot to the frequency spectrum control progress frequency spectrum contained in UI in code.Traditional frequency spectrum
Figure screenshot defect: the screenshot based on UI or control is big to software interface dependence；Cumbersome, the result meeting of screenshot is compared in operation
Because there are inconsistencies for various factors；There are loss of data caused by original image lossy compression；Find the original number with institute screenshot
According to relatively difficult；The needs such as the source to screenshot, authenticity are needed in addition to provide data supporting, it is inconvenient to use；Screenshot lacks
Specification, it appears pattern is more, disunity.
Therefore, for the above status, there is an urgent need to develop a kind of storage of frequency spectrum data based on bitmap show system and
Method, to overcome the shortcomings of in currently practical application.
Summary of the invention

The problems mentioned above in the background art.
To achieve the above object, the invention provides the following technical scheme:
A kind of storage of the frequency spectrum data based on bitmap shows system, includes physical layer, logical layer and interface layer, described
Physical layer is used for the explanation of the definition to storage organization；The logical layer is based on storage organization and generates to coordinate system, is used for frequency spectrum
Drafting, Waterfall plot drafting and figure reverse resolution are schemed into the realization of the Processing Algorithm of data；The interface layer is outer for being supplied to
The description how definition for the interface that portion is called, the main explanation comprising interface parameters and interface call；It the physical layer and patrols
It collects to exist between logical layer and interface layer between layer and interact.
As a further solution of the present invention: the bitmap file of the physical layer include bitmap file head, message bit pattern head,
Color table and the array of bytes for defining bitmap.
As a further solution of the present invention: the interface layer saves frequency spectrum picture by frequency spectrum data for being supplied to user
Interface, and be supplied to the interface that user is converted into frequency spectrum data by frequency spectrum picture.
A kind of storage of the frequency spectrum data based on bitmap shows method, and the algorithm steps of logical layer are as follows:
S1, picture structure initialization；
S2, coordinate system creation；
S3, the storage of parameter；
S4 is parsed and is got parms；
S5, the storage of spectrum amplitude value；
S6 is parsed and is obtained spectrum amplitude data；
S7, the drafting of reference axis, scale；
S8, the drafting of spectrogram；
S9, unserializing frequency spectrum data；
S10, the filling of background colour；
S11 is stored as frequency spectrum data file to external memory；
S12 is stored as bmp file to external memory.
Compared with prior art, the beneficial effects of the present invention are:
1) there is initial data by fusion in its institute's cut-off frequency spectrogram, can be automatically parsed out by program；
2) based on the screenshot of data, and it is not based on interface, keeps its independence good, it is soft without being overly dependent upon test analysis
Part；
3) there is certain normalization to the generation of picture and frequency spectrum data de-parsing；
4) it can be integrated into service, versatility is good, and B/S and C/S are general；
5) data redundancy in bitmap number has effectively been used.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please referring to Fig. 1~6, in the embodiment of the present invention, a kind of storage of the frequency spectrum data based on bitmap shows system, including
There are physical layer 1, logical layer 2 and interface layer 3, the physical layer 1 is used for the explanation of the definition to storage organization；The logical layer 2
