摘　　要：光缆在生活中起着不可替代的作用,尤其在给变电站提供电量的服务过程中至关重要。当光缆进行维修或迁移时,需要精确定位光缆的地下位置。为了解决光缆定位问题,提出了一种基于多阵列麦克风音频信号探测光缆的实验方法。首先,在目标探测区域建立了一个平面直角坐标系,并布置音频信号发射器和音频信号接收器。其次,发射音频振动信号,使其与光缆产生共振;然后,对音频信号接收器接收到的音频信号进行时域和频谱分析;最后,根据共振频率在各个位置的频谱图上的信号强度从而确定光缆的位置。实验结果表明该方法能够有效、准确地定位地下光缆的位置,从而保证变电站的正常运行,并避免光缆损坏。Fiber optic cables play an irreplaceable role in daily life,especially in the service process of providing electricity to substations.When repairing or relocating optical cables,it is necessary to accurately locate their underground location.To solve the problem of fiber optic cable positioning,an experimental method based on multi array microphone audio signal detection for fiber optic cables is proposed.Firstly,a planar Cartesian coordinate system was established in the target detection area,and audio signal transmitters and receivers were arranged.Secondly,the audio vibration signal is transmitted to resonate with the optical cable.Then,the audio signal received by the audio signal receiver is analyzed in time domain and frequency spectrum.Finally,the position of the optical cable is determined based on the signal strength on the frequency spectrum of the resonance frequency at each position.The experimental results show that this method can effectively and accurately locate the location of underground optical cables,ensuring the normal operation of the substation and avoiding cable damage.
