AI Technical Summary
Existing audio and video players cannot accurately time automatic playback, which can easily lead to exam accidents due to human error.
The system uses a Beidou time synchronization module in conjunction with a STC32G12K128-32 microcontroller chip to obtain precise time via serial port connection, enabling timed automatic playback of audio and video players. The current time and status are displayed on an LCD screen, and the playback status is monitored to automatically pause or switch to backup data.
It enables precise, timed, and automatic playback of audio and video players, reducing human error and ensuring the accuracy and reliability of the examination process.
