摘　　要：随着城市建设的快速发展,地下电缆线路外损故障也急剧增多。本文在基于振动信号检测的基础上,提出了一种防止地下电缆压坏的保护方法。通过分析地震波产生原理与传播规律,研究了行人、车辆、施工机械等运动目标所产生的地振动信号特点,利用过零数统计分析的方法对行人、车辆、施工机械等运动目标进行识别,设计了合适的阈值选取原则,搭建了基于NI的振动信号采集和处理的实验平台,完成了振动数据采集,验证了过零数统计分析方法对目标识别的有效性,集成了地下电缆保护预警系统,实现了对进入保护范围的施工机械的探测,达到了保护地下电缆的目的。With the rapid development of urban construction,the external damage of underground cable lines has also increased dramatically.This paper proposes a protection method to prevent the crushing of underground cables based on the detection of vibration signals.Analyzed the seismic wave generation principle and propagation law,studied the characteristics of ground vibration signals generated by moving targets such as pedestrians,vehicles,and construction machinery.Using the method of zero-crossing statistical analysis to identify and design moving targets such as pedestrians,vehicles,and construction machinery The principle of suitable threshold selection was established,an experimental platform for vibration signal collection and processing based on NI was built,vibration data collection was completed,the effectiveness of the zero-crossing statistical analysis method for target identification was verified,and an underground cable protection warning system was integrated.The detection of the construction machinery entering the protection range is realized,and the purpose of protecting the underground cable is achieved.
