Abstract

The present invention relates to the technical field of broadcast communication, in particular to an emergency intelligent broadcast system, including: a broadcast controller, transmission equipment and an intelligent receiving terminal; wherein, the broadcast controller includes an emergency broadcast sound source and a normal broadcast sound source, a sound source selector, a control management Platform, broadcast FM modulator, encoder; in case of emergency, the broadcast controller controls the audio source selector through the control management platform according to the regional division conditions, and according to the broadcast instructions of the broadcast FM modulator and encoder corresponding to the emergency broadcast For the selection of emergency broadcast sound source, the selected emergency broadcast sound source is transmitted to the corresponding intelligent receiving terminal for playback through the transmission equipment, which solves the technical problem that there are regional differences in the prior art and the emergency broadcast information cannot be popularized. Furthermore, the technical effect that the emergency broadcast message can be received through various receiving terminals in each area is realized.

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...
