Problems solved by technology
However, for the monitoring and analysis of the overall electromagnetic environment, especially when dealing with a large amount of monitoring data, data data and various business data, the efficiency is very low. In addition, these data are used in different periods, different departments or even different equipment. It can be seen that it is very difficult to use traditional management and analysis methods

The invention discloses a method for discovering wireless stations and analyzing wireless interference by applying a K line graph. Graphic display is carried out on a change process of amplitude of signals collected by monitoring stations along with time; through combination of a station database, analysis and confirmation are carried out on activity rules and violation condition of the stations, and judgment of two main interference types of whether illegal frequency multiplexing is carried out or not and whether intermodulation interference is generated or not; and operators are assisted in determining locations of illegal stations or interference signals. According to the method, on the basis of a gridded monitoring system for the wireless stations, the K line graph capable of reflecting electromagnetic emission activity condition of the wireless stations is generated based on monitoring data, and the emission activities of the stations are monitored by applying the K line graph. According to the method, the illegal stations can be discovered timely; the illegal frequency multiplexing and intermodulation interference can be analyzed rapidly and accurately; the radio monitoring efficiency can be clearly improved; and great promotion effect is taken in developing radio management towards active, fine and visual directions.
Description
technical field [0001] The invention relates to the technical field of wireless station monitoring, and relates to a method for discovering wireless stations and analyzing wireless interference by using K-line diagrams. Background technique [0002] Radio spectrum resources are limited and very important natural resources. Since radio was applied to the field of communication technology, with the development and progress of human science and technology, it has constituted an essential basic condition for human survival. The use of signals in various bands must be restricted by laws and regulations in order to make the entire communication environment orderly and harmonious. This requires the monitoring system to be able to monitor the signal power, bandwidth, and location of use for legal signals that have obtained frequency use licenses, monitor, demodulate, and accurately locate illegal signals that have not obtained frequency use licenses, and detect illegal wireless stat...
