Abstract

This system centers on high-performance microcontroller AT89S52. Through the motor control on ASSP chip MMC-1 which controlling two DC motors, it can achieve accuracy position control of the moving acoustic. The buzzer can make an aural signal on a certain frequency using the microcontroller AT89S52. Because the distances between the three audio receivers and the moving acoustic are different, the signal they receive has a certain time difference. Then the control system makes a control signal according to the time difference. This signal is transmitted to the moving sound source through a wireless transceiver module and guides its motion.
