工作原理

發(fa)射(she)機(ji)(ji)和(he)接(jie)(jie)收(shou)機(ji)(ji)采用單片機(ji)(ji)編碼、解碼技(ji)術和(he)廣泛應用在通信(xin)(xin)領域里的(de)(de)(de)(de)(de)(de)PSK技(ji)術。在發(fa)射(she)卡(ka)(ka)鉗(qian)上(shang)發(fa)射(she)平均值為0 的(de)(de)(de)(de)(de)(de)相位編碼信(xin)(xin)號(hao)，接(jie)(jie)收(shou)機(ji)(ji)中的(de)(de)(de)(de)(de)(de)單片機(ji)(ji)對接(jie)(jie)收(shou)的(de)(de)(de)(de)(de)(de)信(xin)(xin)號(hao)經過硬件(jian)和(he)軟(ruan)件(jian)的(de)(de)(de)(de)(de)(de)濾(lv)波后(hou)，再進(jin)行相位識(shi)別(bie)。將發(fa)射(she)卡(ka)(ka)鉗(qian)和(he)接(jie)(jie)收(shou)卡(ka)(ka)鉗(qian)的(de)(de)(de)(de)(de)(de)箭頭指(zhi)向電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)終端，當接(jie)(jie)收(shou)機(ji)(ji)卡(ka)(ka)鉗(qian)鉗(qian)住(zhu)某(mou)根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，接(jie)(jie)收(shou)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表右偏，同時(shi)伴(ban)有聲光指(zhi)示。而鉗(qian)住(zhu)其它(ta)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表左偏，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方向與被(bei)(bei)識(shi)別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方向相反，沒有聲光指(zhi)示。這就體(ti)現了(le)被(bei)(bei)識(shi)別(bie)的(de)(de)(de)(de)(de)(de)目(mu)標電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)(de)*性。很容易將被(bei)(bei)識(shi)別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)從多根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中做出明確(que)判別(bie)。又(you)由(you)于被(bei)(bei)識(shi)別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)上(shang)的(de)(de)(de)(de)(de)(de)信(xin)(xin)號(hao)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)強度(du)全線都是一樣的(de)(de)(de)(de)(de)(de)，接(jie)(jie)收(shou)卡(ka)(ka)鉗(qian)在電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)沿線所接(jie)(jie)收(shou)到(dao)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)信(xin)(xin)號(hao)強度(du)*，識(shi)別(bie)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)不受被(bei)(bei)識(shi)別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)長度(du)的(de)(de)(de)(de)(de)(de)限制。
