【正文】 2013年全國大學(xué)生電子設(shè)計競賽簡易照明線路探測儀（K題）【?？平M】2013年9月7日III簡易照明線路探測儀（K題）【?？平M】 【摘要】本簡易照明線路探測儀的設(shè)計是根據(jù)通電導(dǎo)線在其周圍產(chǎn)生磁場的情況下，利用探測其磁場的方法，通過對通電導(dǎo)線所產(chǎn)生的磁場使探測磁頭產(chǎn)生電壓，對此探頭電壓進(jìn)行采樣放大，使其輸出一定大小的波形，通過驅(qū)動蜂鳴器示意，從而達(dá)到對通電線纜的探測。該系統(tǒng)能夠?qū)?0W白熾燈和11W節(jié)能燈通電導(dǎo)線所產(chǎn)生的微弱磁場進(jìn)行探測，從而達(dá)到對帶電線纜的掃描、記錄帶電線纜的走向。在探測結(jié)束后，該系統(tǒng)保存線纜位置方格序號，而且在必要時候能夠隨時查閱線纜位置走向。而且該系統(tǒng)對沒有帶電線纜走過的位置，探測儀不對地球磁場所產(chǎn)生的影響使系統(tǒng)產(chǎn)生誤報，從而可以準(zhǔn)確達(dá)到了檢測指定位置是否有帶電線纜，是理想的簡易照明線路探測儀。 【關(guān)鍵詞】照明線路； 磁場；探測儀[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 earth39。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.【關(guān)鍵詞】照明線路、磁場、探測儀[keyword] lighting circuit； magnetic field； detector目 錄1 系統(tǒng)設(shè)計要求................................................................................................................................1 任務(wù).........................................................................................................................................1 設(shè)計相關(guān)要求.........................................................................................................................12 系統(tǒng)方案論證與選擇....................................................................................................................2 控制模塊................................................... .............. .............. ...............................................2 ....................................................................................................
