Safe broadcasting monitoring system based on video/audio matching technology

The invention relates to a safe broadcasting monitoring system based on video/audio matching technology, comprising a device for supplying a broadcasting signal source, a primary broadcasting switch device of signals, a secondary broadcasting switch device of signals, a device for automatically switching the signals outputted by the primary broadcasting switch device and the secondary broadcasting switch and a broadcasting signal receiving device for receiving signals; a two-path signal matching device for matching two paths of signals is connected between any two paths of signal outputs of the devices. The beneficial effects generated by the invention are that the objective analysis for final-stage broadcasting signal audio technology indexes is realized in the sub-control system of the broadcasting channel by introducing the two-path signal matching device; the monitoring range of safe broadcasting is enlarged, and the safe broadcasting is not limited by artificial subjective judgment, so that the safety of
