Black broadcast detection method and system based on multi-source data fusion

The invention provides a black broadcast detection method and system based on multi-source data fusion, and the method comprises the steps: extracting a plurality of feature parameters in broadcast signal measurement data, carrying out the statistics and combination of the feature parameters through a maximum value, a minimum value and an average value according to different signal time period lengths, and obtaining a combined feature vector; and inputting the combined feature vector into a pre-trained black broadcast detection network, and outputting a judgment result of the broadcast signal. According to the method, multiple features are selected, and multiple statistical analysis is performed on each feature again, so that rich feature vectors are formed, and on the premise that the extraction difficulty is not remarkably increased, the feature vectors can be enriched, and the original essence of black and white broadcast can be better reflected; the black broadcast detection network based on the selected
