針對在(zai)汕頭市第(di)二過海(hai)水(shui)管續建(jian)工(gong)(gong)程(cheng)、丹陽市黃崗取水(shui)工(gong)(gong)程(cheng)和(he)(he)上(shang)海(hai)青草沙水(shui)源地原水(shui)工(gong)(gong)程(cheng)等(deng)測量(liang)中出現的(de)通(tong)訊線(xian)(xian)數量(liang)繁多、布線(xian)(xian)和(he)(he)維護工(gong)(gong)作量(liang)大(da)、故障排(pai)除困難(nan)等(deng)問(wen)題和(he)(he)缺陷，上(shang)海(hai)建(jian)工(gong)(gong)基礎(chu)集團自(zi)主研(yan)發了(le)超長(chang)距離頂(ding)管自(zi)動(dong)測量(liang)系統(tong)，將原系統(tong)的(de)數據傳(chuan)遞方(fang)法由傳(chuan)統(tong)的(de)多線(xian)(xian)連接改為(wei)單線(xian)(xian)連接，通(tong)過給每(mei)臺全(quan)站儀配置(zhi)一(yi)(yi)個帶有(you)地址識別(bie)功能(neng)的(de)雙向(xiang)轉換(huan)器，使所有(you)儀器都采用同(tong)一(yi)(yi)根通(tong)訊線(xian)(xian)與計算機(ji)連接，各臺全(quan)站儀既(ji)能(neng)保持相互獨立，又能(neng)協同(tong)工(gong)(gong)作。該項(xiang)創新成果已經在(zai)上(shang)海(hai)白龍(long)港(gang)一(yi)(yi)超長(chang)距離頂(ding)管施工(gong)(gong)中成功應用并(bing)申請專利。與傳(chuan)統(tong)的(de)多線(xian)(xian)連接相比，單線(xian)(xian)連接不僅大(da)大(da)降低(di)了(le)成本，節省(sheng)了(le)時(shi)間，還提(ti)高了(le)超長(chang)距離頂(ding)管自(zi)動(dong)測量(liang)系統(tong)的(de)可(ke)靠性。
