摘要
介绍了一种以AVR单片机为核心的智能型带电电缆路径检测仪的实现方法。该路径检测仪可根据电缆中信号频率已知或未知2种情况,分别采用特定频率检测和未知频率搜索2种工作模式,并通过线圈所产生的感应电动势的大小来判断电缆位置,从而在不影响电缆正常工作的情况下,实现对地下电缆路径的检测。
The paper introduced implementation of an intelligent path detector for electrified cable with AVR single-chip microcomputer as core. The path detector provides two operating modes of specific frequency detection and unknown frequency search for two cases of signal frequency known or unknown respectively, and determines position of the cables according to induced electromotive force generated by the coil, thus realizes detection of underground cable path without affecting normal working of the cable.
