Abstract

The invention relates to the technical field of broadcast communication, in particular to an intelligent emergency broadcast system. The intelligent emergency broadcast system comprises a broadcast controller, transmission equipment and intelligent receiving terminals. The broadcast controller comprises emergency broadcast sound sources, normal broadcast sound sources, a sound source selector, a control management platform, a broadcast frequency modulation modulator and an encoder. Under an emergency situation, the broadcast controller controls the sound source selector to select the emergency sound sources through the control management platform according to the region division condition and according to the broadcast commands of the broadcast frequency modulation modulator and the encoder corresponding to emergency broadcasts. The selected emergency broadcast sound sources are transmitted to the corresponding intelligent receiving terminals through the transmission equipment to be broadcasted. By means of the intelligent emergency broadcast system, the technical problem that in the prior art, for regional difference, the emergency broadcast information cannot be popularized is solved, and the technical effect that the emergency broadcast information can be received through various receiving terminals in all regions is achieved.

Description

technical field [0001] The invention relates to the technical field of broadcast communication, in particular to an emergency intelligent broadcast system. Background technique [0002] Emergency broadcasting is a very important communication channel to deal with major events. The existing emergency broadcasting system can broadcast through FM signals and digital TV. However, due to the limitations of regional conditions and other conditions, some areas can only receive broadcasts of FM signals, and some areas can only receive broadcasts of digital TV. If only one form of broadcast signal is sent at the broadcast terminal, then some areas have no When the terminal equipment corresponding to this kind of broadcast signal is installed, the current emergency broadcast cannot be received, so that the emergency broadcast cannot be popularized, which brings a lot of inconvenience to people's life. Contents of the invention [0003] The embodiment of the present invention provid...
