RFID와 GPS 시스템을 이용한 강재 물류 자동화 시스템의 구현에 대한 연구

Abstract

The best fact is steel in shipyard. it's like flowing the money and flowing the manufacturing process. So, a lot of manager have made an effort to grasp the flowing the steel. But, they could not. The newest technology with RFID and GPS is coming up. So, we can grasp flowing the sill. The flowing steel is including move, unloading, stock, supply. The first, input all of the information with the steel to the RFID, when the sill contractor is moving steel. and then attach the GPS on the trailer. The ship manufacturing manager can grasp the sill, where is it. Use that information, they can make the point of worktime. When steel is through the gate of shipyard, the steel information take over automatically by RFID. The information is input in the database system. So, they use it for make their day schedule or week schedule. The RFID has coordinate of steel. So, the crane is taking steel automatically and moving the manufacturing factory. Before all of steel moving was managed manually. So, it needs a lot of worker. But after change the system. It just needs 10~20% worker compare with before. and reduce the mistake by worker, when the information is moving. So, reduce 2billion. Now, it is under the trial operating.
