Oral implantation safety assistance system and method based on sound signals

The invention provides an oral implantation safety assistance system and method based on sound signals. An implantation mobile phone is installed at the tail end of a mechanical arm, and oral implantation drilling operation is completed under driving of a robot controller; a miniature microphone is located at the tail end of the mechanical arm and used for converting drilling sound into an electric signal and transmitting the electric signal into a sound collector; the sound collector is used for converting the sound analog quantity into digital quantity and transmitting the signal to an industrial personal computer; and the industrial personal computer performs signal analysis on the received sound, judges whether the drilling state is safe or not, and sends an instruction to the robot controller to control whether the mechanical arm continues drilling or not. According to sound signals generated by drilling, safety monitoring is conducted on the drilling process, and the drilling safety of the robot is guar
