產品概述：

電纜識別儀電纜檢測儀，與常(chang)規的識(shi)(shi)別(bie)儀不同(tong)，采用(yong)了(le)的通(tong)信(xin)(xin)技(ji)(ji)術，在發(fa)射(she)端采用(yong)單(dan)片機(ji)技(ji)(ji)術對(dui)(dui)發(fa)射(she)信(xin)(xin)號進行(xing)編(bian)碼(ma)、功率驅動(dong)，將信(xin)(xin)號耦合到電(dian)(dian)纜上；接收(shou)(shou)機(ji)中的單(dan)片機(ji)對(dui)(dui)接收(shou)(shou)的相位編(bian)碼(ma)信(xin)(xin)號解碼(ma)和相位識(shi)(shi)別(bie)。根據(ju)目標電(dian)(dian)纜上的信(xin)(xin)號相位特征將目標電(dian)(dian)纜從一(yi)(yi)大束電(dian)(dian)纜中識(shi)(shi)別(bie)出來。因(yin)此工作性能(neng)(neng)可(ke)靠，對(dui)(dui)超長電(dian)(dian)纜也能(neng)(neng)做到準確判別(bie)，是一(yi)(yi)種(zhong)輕小型(xing)(xing)、緊湊型(xing)(xing)、便(bian)攜(xie)式儀器(qi)。適用(yong)于各種(zhong)類型(xing)(xing)的高低壓(ya)動(dong)力電(dian)(dian)纜。

 工作原理:

發射(she)(she)(she)機(ji)和(he)接(jie)(jie)收(shou)(shou)機(ji)采用(yong)單(dan)片機(ji)編(bian)碼、解碼技術和(he)廣(guang)泛應用(yong)在(zai)通(tong)信領域(yu)里的(de)(de)(de)(de)PSK技術。在(zai)發射(she)(she)(she)卡(ka)鉗上發射(she)(she)(she)平均值(zhi)為(wei)0 的(de)(de)(de)(de)相位(wei)編(bian)碼信號(hao)，接(jie)(jie)收(shou)(shou)機(ji)中的(de)(de)(de)(de)單(dan)片機(ji)對接(jie)(jie)收(shou)(shou)的(de)(de)(de)(de)信號(hao)經過硬件(jian)和(he)軟件(jian)的(de)(de)(de)(de)濾波后(hou)，再進行相位(wei)識(shi)別(bie)(bie)。將(jiang)發射(she)(she)(she)卡(ka)鉗和(he)接(jie)(jie)收(shou)(shou)卡(ka)鉗的(de)(de)(de)(de)箭頭指(zhi)向(xiang)電(dian)(dian)(dian)(dian)(dian)纜(lan)終(zhong)端(duan)，當(dang)接(jie)(jie)收(shou)(shou)機(ji)卡(ka)鉗鉗住(zhu)某根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)纜(lan)，接(jie)(jie)收(shou)(shou)機(ji)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)右偏，同時伴有(you)聲光(guang)指(zhi)示(shi)。而鉗住(zhu)其它(ta)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)左偏，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)向(xiang)與被識(shi)別(bie)(bie)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)向(xiang)相反，沒有(you)聲光(guang)指(zhi)示(shi)。這就(jiu)體現(xian)了(le)被識(shi)別(bie)(bie)的(de)(de)(de)(de)目標電(dian)(dian)(dian)(dian)(dian)纜(lan)。很容易(yi)將(jiang)被識(shi)別(bie)(bie)電(dian)(dian)(dian)(dian)(dian)纜(lan)從(cong)多根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)纜(lan)中做出明確(que)判(pan)別(bie)(bie)。又由(you)于被識(shi)別(bie)(bie)電(dian)(dian)(dian)(dian)(dian)纜(lan)上的(de)(de)(de)(de)信號(hao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)強度全(quan)線都(dou)是一樣的(de)(de)(de)(de)，接(jie)(jie)收(shou)(shou)卡(ka)鉗在(zai)電(dian)(dian)(dian)(dian)(dian)纜(lan)沿線所(suo)接(jie)(jie)收(shou)(shou)到的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁信號(hao)強度*，識(shi)別(bie)(bie)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)不(bu)受被識(shi)別(bie)(bie)電(dian)(dian)(dian)(dian)(dian)纜(lan)長度的(de)(de)(de)(de)限制。
