針對在(zai)汕頭市第二過海(hai)(hai)水(shui)(shui)管(guan)續(xu)建工(gong)(gong)程、丹陽市黃崗取(qu)水(shui)(shui)工(gong)(gong)程和上(shang)海(hai)(hai)青草沙水(shui)(shui)源(yuan)地(di)原水(shui)(shui)工(gong)(gong)程等測量(liang)(liang)(liang)中出現的(de)(de)通訊線(xian)數量(liang)(liang)(liang)繁多(duo)、布線(xian)和維護工(gong)(gong)作量(liang)(liang)(liang)大(da)、故障(zhang)排除困難等問(wen)題和缺陷(xian)，上(shang)海(hai)(hai)建工(gong)(gong)基礎集團自主研(yan)發了超長距離頂管(guan)自動(dong)測量(liang)(liang)(liang)系統(tong)，將原系統(tong)的(de)(de)數據傳遞方法由傳統(tong)的(de)(de)多(duo)線(xian)連接(jie)(jie)改為(wei)單(dan)(dan)線(xian)連接(jie)(jie)，通過給每臺全站儀(yi)配置一(yi)個(ge)帶有地(di)址識(shi)別功(gong)能(neng)的(de)(de)雙向轉換器(qi)，使所(suo)有儀(yi)器(qi)都采用同一(yi)根通訊線(xian)與計(ji)算(suan)機連接(jie)(jie)，各臺全站儀(yi)既(ji)能(neng)保(bao)持相互獨(du)立，又能(neng)協(xie)同工(gong)(gong)作。該(gai)項創新成(cheng)(cheng)果已經(jing)在(zai)上(shang)海(hai)(hai)白龍港一(yi)超長距離頂管(guan)施工(gong)(gong)中成(cheng)(cheng)功(gong)應用并(bing)申請專利(li)。與傳統(tong)的(de)(de)多(duo)線(xian)連接(jie)(jie)相比，單(dan)(dan)線(xian)連接(jie)(jie)不僅大(da)大(da)降低了成(cheng)(cheng)本，節省了時間，還提高了超長距離頂管(guan)自動(dong)測量(liang)(liang)(liang)系統(tong)的(de)(de)可(ke)靠性。
