Design of intelligent car based on sound source guidance

This design includes two parts, namely sound source transmitting system (mobile car) taking STC89C52 SCM as core control and sound source receiving system taking STC5410AD SCM as core control. This system determines the direction and position of sound source through time delay estimation algorithm, carries out distance localization of sound through phase-lock demodulation of the sound source signal and then gives out instructions to the car through wireless transmitting module to control stepping motor to make the car move corresponding steps and display related data and control sound source to move to the assigned position. The ultimate goal of the sound source receiving and transmitting system is to serve mobile cars and the auditory information provided by it will guide the motion path of the robot.
