With the rapid development of science and technology, the application of intelligent robot more widely. Sound source search robot is a kind of intelligent robot, it will be mobile robot technology and sound source search technology organically combined, realize the automatic search of sound source, has become one of research hotspots at home and abroad in recent years.
This paper designed a hold by STC Micro launch of the single chip microcomputer STC12C5A60S2 as the control core of the sound source robot, the robot can automatically search the voice, and get to the designated place, also sounded the alarm. In this paper the overall design, the sound source search is the key. Therefore, in order to overcome the problem of two point method testing the sound source location is not accurate, this paper adopts triangle microphone array structure for sound source localization, improve the precision of positioning. Triangle structure of the microphone array is formed by the three sound sensor collected time difference is different, the general location of sound source. In order to overcome the problem of inaccurate judging robot voice direction, this paper puts forward to multiple microphone channel synchronized sampling, the idea of synchronous processing, and detailed circuit are designed. Three-terminal voltage regulator integrated circuit characteristics can be for several modules and power supply at the same time, so in this paper, a three-terminal voltage regulator power supply module USES integrated circuits, solved a power supply can only give a module power supply problems. Because of the dc motor control is simple, performance outstanding, dc power supply is easy to implement, therefore, this article design module of motor is controlled by dc motor L298N. Through the motor forward, reverse and stop intelligent mobile robot. This paper chooses a ultrasonic module, in the front end, of the smart car by emitting and receiving circuit to realize the obstacle avoidance of robot functions. Display module designed in this paper, when the sound source search robots managed to find a fixed frequency and amplitude of the sound source, the SCM control signal, lit LED lights and signals alarm buzzer.
Experiments show that the robot can avoid obstacles, through three sound sensor receives the time to search the sound source, and provide an alarm. Achieve the robot can search and find the sound source design target sound.
