The invention relates to a black broadcast intelligent monitoring system and a detection method thereof. The black broadcast intelligent monitoring system comprises black broadcast intelligent monitoring nodes and background analysis software, wherein the black broadcast intelligent monitoring node is composed of a positioning unit, a black broadcast monitoring unit, a data transmission unit and the like, and the background analysis software is black broadcast intelligent monitoring software installed in a background computer. Aiming at mobile drive test or fixed networking monitoring of blackbroadcast, a black and white list mechanism is adopted, a mode of combining sweep frequency monitoring and fixed frequency monitoring is used, positioning data, sound, SNR or level values and the like of black broadcast frequency points are visually displayed on an upper computer, and information such as black broadcast transmitting positions and the like is visually displayed. A black and whitelist mechanism is adopted, the monitoring efficiency can be greatly improved, modular design is adopted, and high reliability is achieved.
Description
technical field [0001] The patent of the present invention relates to electronic information technology, in particular to a black broadcast intelligent monitoring system and its detection method. Background technique [0002] Black broadcasting refers to illegal broadcasting stations set up privately without the approval of the radio and television authorities and the radio management department. They are often used in the FM broadcasting frequency band, mainly for commercial activities such as illegal drugs and illegal sales, which have caused great harm to aviation safety and social livelihood. great harm. [0003] The existing black broadcast monitoring technology usually uses a fixed station to monitor and find the direction first, and then moves to approach and search, which is relatively passive in use, and has the following shortcomings: First, because the fixed station provides a single-frequency point of direction to measure Direction positioning, for black broadca...
