Display system and display equipment pickup recovery method

The embodiment of the invention belongs to the commercial display technology, and provides a display system and a display device pickup recovery method, and the display system comprises a display device and a sound amplification microphone. The display device comprises a controller, an audio and video module and a microphone. Wherein the controller comprises a sound amplification microphone recovery circuit; the controller receives an audio signal collected by the sound amplification microphone and sends the audio signal to the audio and video module through the sound amplification microphone recovery circuit, so that the audio and video module judges whether the audio signal is higher than an audio threshold value or not; and if the audio signal is higher than the audio threshold value, the audio and video module controls the microphone to be turned off, converts the audio signal into a USB signal, and sends the USB signal to the controller. According to the invention, when the sound amplification microphone
