工作原理:
為了可靠準確地(di)識(shi)別(bie)電(dian)纜(lan),需要(yao)(yao)給(gei)被識(shi)別(bie)電(dian)纜(lan)加一特殊的信號,該(gai)信號要(yao)(yao)被接(jie)(jie)收(shou)機接(jie)(jie)收(shou),利用這一特性便能(neng)識(shi)別(bie)出要(yao)(yao)找的電(dian)纜(lan)。
發生(sheng)器將周期性的(de)(de)單極性電(dian)(dian)(dian)(dian)(dian)壓脈沖饋入要(yao)(yao)(yao)識(shi)別的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜中(zhong),該電(dian)(dian)(dian)(dian)(dian)纜需要(yao)(yao)(yao)在遠端接地(di),以保證(zheng)有足(zu)夠大(da)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)流(liu)(liu)(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)纜。該系(xi)統要(yao)(yao)(yao)設計(ji)成返回(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不(bu)要(yao)(yao)(yao)從(cong)同一(yi)(yi)電(dian)(dian)(dian)(dian)(dian)纜中(zhong)返回(hui),能做到(dao)這一(yi)(yi)點,饋入電(dian)(dian)(dian)(dian)(dian)纜中(zhong)的(de)(de)脈沖電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)方向可做為(wei)一(yi)(yi)明顯的(de)(de)識(shi)別標準,流(liu)(liu)(liu)(liu)出(chu)(chu)去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)僅(jin)從(cong)這一(yi)(yi)根電(dian)(dian)(dian)(dian)(dian)纜通(tong)過,所(suo)有其(qi)它鄰近(jin)電(dian)(dian)(dian)(dian)(dian)纜中(zhong)流(liu)(liu)(liu)(liu)過的(de)(de)都是(shi)返回(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu),但(dan)它們的(de)(de)極性相(xiang)反。除了電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方向這一(yi)(yi)實際差(cha)異外,電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)幅度也是(shi)一(yi)(yi)識(shi)別特征,流(liu)(liu)(liu)(liu)出(chu)(chu)去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)僅(jin)通(tong)過一(yi)(yi)根電(dian)(dian)(dian)(dian)(dian)纜、而返回(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)可通(tong)過幾根電(dian)(dian)(dian)(dian)(dian)纜、這意味著流(liu)(liu)(liu)(liu)出(chu)(chu)去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)比流(liu)(liu)(liu)(liu)過其(qi)它電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)返回(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)大(da)。
