System and method for storing and displaying frequency spectrum data based on bitmap

Abstract

The invention discloses a system and a method for storing and displaying frequency spectrum data based on a bitmap. The system comprises a physical layer, a logic layer and an interface layer; the physical layer is used for explaining the definition of the storage structure; the logic layer is used for realizing a processing algorithm for drawing a spectrogram, drawing a waterfall chart and reversely analyzing a graph into data; the interface layer is used for defining an interface provided for external calling; and mutual interaction exists between the physical layer and the logic layer and between the logic layer and the interface layer. According to the invention, original data are fused in a frequency spectrogram and can be automatically analyzed by a program; screenshots are based ondata but not based on an interface, so that the independence of the system is good, and the system does not excessively depend on test analysis software; certain normativity is achieved on picture generation and spectrum data inverse analysis; the system can be integrated as a service, has good universality, and is universal for B / S and C / S; and data redundancy in the number of bitmaps is effectively utilized.

Description

technical field [0001] The invention relates to the technical field of radio monitoring, in particular to a system and method for storing and displaying bitmap-based spectrum data. Background technique [0002] In radio monitoring technology, it often involves the graphical display of spectrum data in documents or reports. The spectrum diagram in this document comes from the running screenshot of the graphical spectrum control in the monitoring or analysis software. These screenshots require raw data and paired software for authenticity and correctness verification. Obviously, the separation of screenshots and data makes verification costly. The rendering method of the UI, the stretching of the control, the aspect ratio of the display, the location of the screenshot area, etc. will all become factors that affect the screenshot and change the bitmap. [0003] For the current spectrum diagram screenshot, in addition to manually capturing the interface of the relevant softwar...

AI Technical Summary

Problems solved by technology

Defects of traditional spectrogram screenshots: Screenshots based on UI or controls are highly dependent on the software interface; the operation is relatively cumbersome, and the results of screenshots will be inconsistent due to various factors; there is data loss caused by lossy compression of the original image; It is difficult to find the original data of the screenshot; it is necessary to provide additional data support for the source and authenticity of the screenshot, which is inconvenient to use; the screenshot lacks specifications, and it appears that there are many styles and are not uniform
