全国大学生电子设计竞赛简易照明线路探测仪（K 题）【专科组】2013 年 9 月 7 日简易照明线路探测仪（K 题）【专科组】 【摘要】本简易照明线路探测仪的设计是根据通电导线在其周围产生磁场的状况下，运用探测其磁场的措施，通过对通电导线所产生的磁场使探测磁头产生电压，对此探头电压进行采样放大，使其输出一定大小的波形，通过驱动蜂鸣器示意，从而达到对通电线缆的探测。该系统可以对60W白炽灯和11W节能灯通电导线所产生的微弱磁场进行探测，从而达到对带电线缆的扫描、记录带电线缆的走向。在探测结束后，该系统保留线缆位置方格序号，并且在必要时候可以随时查阅线缆位置走向。并且该系统对没有带电线缆走过的位置，探测仪不对地球磁场所产生的影响使系统产生误报，从而可以精确达到了检测指定位置与否有带电线缆，是理想的简易照明线路探测仪。 【关键词】照明线路； 磁场；探测仪[Abstract] the design of simple lighting circuit detector is based on the electrical wire in electric current produces a magnetic field principle, using the method of detecting the magnetic field, by which produces to the electrified wire magnetic field makes the detection head generates a voltage, this voltage sampling probe amplification, so that the output of a certain size by driving waveform, buzzer hint, so as to achieve the detection of power cable. The system is capable of weak magnetic field generated by the 60W lamp and 11W lamp wire to detect, so as to achieve the charged cable scanning, recording live cable. In the end position detection, cable box number to save the system, but also can access at any time to cable position when necessary. And the system of no electric cable through the position, effect of the earth's magnetic field detector does not generate false positives generated by the system, which can accurately reach the designated position detection whether charged cable, is a simple lighting circuit ideal detector.[keyword] lighting circuit；...
