| description | The utility model discloses an intelligent audio switcher for emergency broadcast. The intelligent audio switcher comprises a main control chip, the main control chip is respectively connected with the FM demodulation module, the telephone communication module, the network module, the audio encoding and decoding module, the audio detection circuit and the audio signal switching module; the FM demodulation module and the telephone communication module are both connected with the audio signal switching module; the audio detection circuit receives transverse broadcast audio and transmits the transverse broadcast audio to the main control chip and the audio signal switching module. The device supports multi-channel IP interface input, multi-channel audio input and dual-track audio output, and is used as a county-level platform middleware; when the equipment is accessed to a county-level platform, a user can perform priority setting according to broadcasting requirements of access signals so as to meet the require |
