| 摘 要： | 声源定位在当今日益智能化的社会中有着诸多方面的应用，特别是在智能控制，军事等领域。文中设计的系统以MSP430F449单片机为控制核心，步进电机驱动的小车作为移动声源载体，设计两个间距固定的麦克风作为接收设备，测量声源发声到麦克风接收到声音的时间差数据，声源通过无线模块接收到数据从而计算出声源的坐标，然后控制声源小车运行到指定坐标实现定位控制。经测试，本系统能精确的控制小车到达指定坐标点，系统工作稳定。

| Abstract: | Sound localization has many applications in nowadays higly intelligentized society,especially used in fields of intelligent control andmilitary. In order to design a sort of sound localization system,this approach regarded MSP430 as the system control center,used a stepper motor car as a mobie sound source vector and design two microphones to detect time difference of sound source transmission to two microphones, the time difference was sended to the sound source wirelessly and the coordinates of sound souce can be calculated,then the sound source car was controled to move to destinantion coordinates precisely. Experiment showed that the system can control the sound source car move to destination coordinates precisely and the system worked stably. |
