摘要
随着社会的发展,地下电缆在城市建设中越来越重要,但是由于地下电缆分布复杂,监管不足,因外力破坏导致的地下电缆事故频频发生。本文介绍了现阶段提出的多种地下电缆防护措施并分析优缺点,其中,基于声音传感器的预警型防护措施最符合地下电缆防护的应用。当前,基于声音传感器的预警型防护措施主要采用声纹识别技术,本文提出声源定位技术与声纹识别技术结合的方法,分析各类声源定位技术的优缺点,得出基于到达时间差(TDOA)的声源定位技术在地下电缆防护中最具有可实现性。
With the development of society,underground cables are becoming more and more important in urban construction.However,due to the complex distribution of underground cables and insufficient supervision,there are many accidents by external force damage often occur.This article introduces a variety of underground cable protection solutions proposed at this stage and analyses their advantages and disadvantages.Among them,the early warning protection solutions based on sounds sensors are most suitable for the application of underground cable protection.At present,the early warning protection solutions based on sound sensors mainly use voiceprint recognition technology.This article proposes the combination of sound source localization technology and voiceprint recognition technology,introduces some characteristics of various sound source localization technologies,and obtains a sound source based on Time Difference of Arrival(TDOA)is the feasibility of positioning technology in underground cable protection.
