Embodiment 1

[0061] see figure 1 with image 3 , a kind of environmental threshold interference detection method of the present invention, adopt monitoring equipment to analyze and process the data collected, it is characterized in that:

[0062] a. Environmental sample collection: use at least one eagle-eye radio monitoring sensor as a sampling device to collect some environmental spectrum data in the area of ​​interest and the time period of interest without interference, and the frequency range of the sample collection needs to be consistent with the sampling device The highest scanning bandwidth is consistent, and the spectral characteristic coefficients are obtained according to the environmental spectrum data for queuing noise interference, and the fluctuation range of normal signals is obtained; the environmental spectrum data includes monitoring start and end time, maximum hold spectrum, average spectrum, minimum spectrum, real-time Spectrum, longitude and latitude coordinates of ...

Abstract

The invention relates to the technical field of signal interference detection, and specifically relates to an environmental threshold interference detection method. Collected data is analyzed and processed by monitoring equipment. The environmental threshold interference detection method is characterized by comprising the following steps: (a) collecting environmental samples; (b) monitoring the environmental threshold in real time; (c) carrying out abnormal signal judgment and alarm; (d) analyzing and judging whether an abnormal signal is an interference signal; and (e) processing the abnormalsignal analysis result. Compared with the prior art, the automatic degree of interference discovery is improved, there is no need for manual duty, and manpower is saved; the accuracy of interferencediscovery is improved, and false alarm and missing alarm are reduced; the method supports post analysis of interference monitoring, and the analysis workload is reduced; a punishment basis is providedfor the investigation of interference; and interference signals can be automatically analyzed and positioned.

Description

technical field [0001] The invention relates to the technical field of signal interference detection, in particular to an environmental threshold interference detection method. Background technique [0002] With the increasing popularity of radio applications such as mobile phones, broadcasting, satellite communications, and navigation, the situation of application interference is also becoming more and more serious. In order to avoid the loss of economy and life and property safety caused by interference, people pay more and more attention to the timeliness of discovering interference; [0003] There are various reasons for interference, for example: artificially generated such as illegal use of frequency bands for data communication, and abnormal equipment conditions such as poor grounding of lighting headlights, irregular interference caused by intermittent on and off, and equipment transmission. Intermodulation interference, etc. [0004] Factors affecting interference...
