摘　　要：在日常生活中,为了检测埋在墙里面的照明线路的布置情况,设计了本探测仪。该照明线路探测仪以电磁感应理论和单片机技术为基础,采用STC89C52单片机为核心控制芯片,采用高精度低噪声差动放大器以及三态缓冲电路,经过多次耦合和放大后,输入到LM324比较器,经过比较后把该电信号输入到单片机进行处理,最终确定是照明线路的位置。In daily life, in order to detect the arrangement of the illuminating line buried in the wall, this detecting instrument is designed. This detecting instrument of the illuminating line is based on the electromagnetic coupling principle and single chip microcomputer technology. It uses STC89C52 single chip microcomputer as the core control chip and uses the high-precision and low-noise differential amplifier and tristate snubber circuit. After a lot of coupling and enlarged, the electric signal is put into the LM324 comparator. After comparing, the electric signal is put into the single chip microcomputer for processing, and finally the location of the illuminating line can be determined.
