摘　　要：通过声音引导系统可对一定范围内的可移动声源进行定位和引导其移向预定区域。该系统中,将蜂鸣器固定在小车上作为可移动声源,3个声音接收装置固定在地面上,通过计算声源信号到达两个接收器的时间差来确定声源位置,并引导其向指定位置运动。接收单元与可移动声源之间通过无线传输方式完成数据的传输,从而实现声源的精确定位和控制。整个系统电路简单,功能完善,并且功耗低,性价比高。The localization of moving sound source in a given range can be implemented through sound localization guidance system and it can be led to moving to the preset area. In this system, a buzzer was used as moving sound source which was fixed on a small car and three sound receivers were fixed on the ground. The sound source was located by calculating the time difference that sound source signal arrives at two receivers respectively, and the moving sound source was led to moving to the given position. The data between receiving unit and moving sound source were transmitted through wireless transmission mode. The precise localization and control of the sound source are realized. The system has simple electrical circuit, perfect functions, low power loss and high performance-to-price ratio.
