Abstract
The present disclosure provides a kind of playing control device of inductive switching audio, including processor and switch module;When processor is powered on and normally works, first control signal is output to switch module, so that the second switch input end of switch module is connected with switch output end;When network broadcast audio reception is normal, processor receives network broadcast audio and local audio, and is played by being output to local amplification equipment through switch module;When network broadcast audio reception is abnormal, processor receives first backup audio and local audio, and is played by being output to local amplification equipment through switch module;When processor is powered off or fails, processor cannot output control signal to switch module, so that the first switch input end of switch module is connected with switch output end, and second backup audio is transmitted to local amplification equipment and played through switch module.In network broadcast audio reception is abnormal or in broadcast equipment power failure or equipment failure, backup audio can be played, and the reliability of broadcast broadcast is improved.
