摘要: 為滿足石油行業(yè)對(duì)回收鉆桿進(jìn)行質(zhì)量監(jiān)測(cè)和分級(jí)評(píng)價(jià)的迫切需要,開(kāi)發(fā)了一套回收鉆桿自動(dòng)化檢測(cè)分級(jí)生產(chǎn)線,以替代目前的手工操作。利用基于鉆桿旋轉(zhuǎn)的自動(dòng)化漏磁和超聲波復(fù)合無(wú)損探傷系統(tǒng)、基于激光測(cè)量的形位尺寸自動(dòng)化測(cè)量系統(tǒng)以及鉆桿自動(dòng)化分級(jí)裝備,設(shè)計(jì)了一種基于局域網(wǎng)、以太網(wǎng)、MPI網(wǎng)絡(luò)和PROFIBUS-DP現(xiàn)場(chǎng)總線的網(wǎng)絡(luò)化控制方案,集成檢測(cè)信號(hào)和分級(jí)信息,實(shí)現(xiàn)了對(duì)生產(chǎn)線的自動(dòng)化集散控制?，F(xiàn)場(chǎng)應(yīng)用證明,該回收鉆桿檢測(cè)分級(jí)控制系統(tǒng)運(yùn)行穩(wěn)定可靠,極大地提高了工作效率和產(chǎn)品質(zhì)量,具有較高的應(yīng)用價(jià)值。Abstract: In order to meet the urgent need for quality monitoring and classification evaluation of recycled drill pipes,an automatic detection and classification operation line is developed to replace the currently-adopted manual operation.Composed of the MFL/UT combined NDT system as working with the drill pipe rotating,the automatic geometrical dimension laser measurement system and the automatic classification equipment,a net-worked control system is designed based on Local Area Network,Ethernet,MPI and PROFIBUS-DP,which is capable of integrating inspection data and classification information so as to realize the automatic collection/dis-tribution control of the production line.The actual site application result proves that the newly-developed control system that features reliable and consistant running has significantly improved production efficiency and product quality as well.
