摘要
提出了一种基于电磁法的地下电力电缆路径检测的系统,该系统针对同时含有运行状态和非运行状态电缆的待测现场,利用高灵敏度的三轴磁阻传感器在地面上方测得待测磁场信号的三维分量,经预处理电路对磁场信号进行去噪和选频处理后,通过磁场检测模型计算得到地下电缆的路径走向,实现对运行电缆和非运行电缆路径的智能检测。MATLAB和MULTISIM分别仿真验证磁场检测模型和预处理电路的可行性,表明该系统对地下电力电缆路径智能检测具有较好的实用性。
An underground power cable path detection system based on electromagnetic method is proposed in this paper. This system aiming at the test site containing both running and non-running state of the cable,measures the three components of the magnetic field by three-axis high sensitivity magneto-resistive sensors above the ground,and uses pre-processing circuit to eliminate interference,then calculates the specific location of underground cables and the path toward by the magnetic field detection model,and completes the running and non-running cables＇ intelligent path detection. MATLAB and MULTISIM simulation respectively verify the feasibility of the magnetic field detection model and pre-circuit,which indicates that the system of underground power cable path intelligent detection has good practicality.
