Problems solved by technology

However, it does not solve the problem that when there are many radio signals received, the generation of spectrum data is slow. Therefore, the efficiency of spectrum monitoring is low, and it cannot meet the current demand for faster spectrum monitoring.

Embodiment approach

[0052] As an optional implementation, the method also includes:

[0053] If the target radio device is an unregistered device, store the ID, spectrum data and location of the target radio device.

[0054]As an optional implementation, preprocessing the frequencies specifically includes:

[0055] The frequency is processed by an optimization algorithm to obtain the preprocessed frequency.

[0056] As an optional implementation manner, step 103 specifically includes:

[0057] Get spectrum data for registered devices.

[0058] It is judged whether the spectrum data of the target radio device is the same as the spectrum data of the registered device.

[0059] If yes, the target radio device is a registered device; if not, the target radio device is an unregistered device.

[0060] Specifically, the spectrum data of the target radio device being the same as the spectrum data of the registered device includes: the transmission bandwidth of the target radio device is the same as ...

Abstract

The invention discloses a frequency spectrum monitoring method and system. The method comprises the following steps: acquiring equipment information of target radio equipment, wherein the equipment information comprises frequency and position; carrying out single-point iterative operation on the frequency of the target radio equipment by adopting a Goertzel algorithm to obtain frequency spectrum data of the target radio equipment, wherein the spectrum data comprises a transmitting bandwidth and a center frequency; and judging whether the target radio equipment is registered equipment or not according to the frequency spectrum data of the target radio equipment. According to the method, the Goertzel algorithm is used for Fourier transform of the frequency of the target radio equipment, the algorithm is higher in calculation efficiency compared with a fast Fourier algorithm, the Goertzel algorithm uses a recursive calculation structure, the occupied storage is small, the precision is high, and the time domain data of multiple radio equipment can be quickly sampled, so that the time domain data of the multiple radio equipment can be quickly sampled, the interception speed of illegal radio signals is improved, and the monitoring efficiency of radio equipment is improved.

Description

technical field [0001] The invention relates to the technical field of radio spectrum monitoring data processing, in particular to a spectrum monitoring method and system. Background technique [0002] In recent years, with the continuous improvement of hardware performance, the large-scale application of radio technology has become possible. The application of radio technology in the communication field is more and more extensive, which provides great convenience for people's life. However, the rapid development of radio technology also makes the competition for spectrum resources more and more tense. Because the electromagnetic spectrum is limited in a certain time and frequency band, although the use range of the radio spectrum is stipulated internationally as 9kHz-275GHz, in practical applications, it is usually only below tens of GHz. The use of a large number of illegal devices has made the already limited spectrum resources even more scarce. In view of the above re...
