초록

다양한 생산 설비에 따른 설비정보를 MES 등의 생산시스템에 효율적으로 제공하기 위해 설비 정보 수집 시스템은 생산현장의 설비 및 공정특성을 고려한 다양한 설비 인터페이스에 따른 정보 수집이 필요하다. 본 연구에서는 생산현장의 다양한 생산 설비의 정보를 수집하기 위해 설비 인터페이스를 통한 설비정보 수집 방법을 제안한다. PLC 기반의 인터페이스, Sensor 기반의 I/O 인터페이스, 작업자 Key-In 에 의한 인터페이스 등 다양한 설비 인터페이스를 통해 생산 현장의 정보를 1 차 수집할 수 있다. 데이터 수집 시스템은 H/W Communication Module 과 Operator Key-In Module을 이용하여 설비 인터페이스를 통해 수집되는 설비 정보를 2 차 가공하며, 데이터 파서(Data Parser)를 통해 수집 정보의 유연성을 높일 수 있다.

There is much information of equipment in shop floor because the manufacturing processes are different as the equipment within the manufacturing process is varied. To provide effective process information to MES and other production systems, the DAS requires an equipment monitoring system that takes into account the characteristics of the equipment on the shop floor. In this study, we proposed some methods for collecting the required information about various equipments on a shop floor. The equipments such as CNC can be interfaced with the DAS by using a PLC-based method and a sensor-based interface board can be used to interface general equipments. The proposed methods can be used to collect information on the shop floor in real-time. Moreover these methods are very adaptive and can be easily modified according to the changes made to the shop floor. The information about a real shop floor acquired by employing these methods is saved in a database and the can be provided to a supervisor and MES so that they are aware of the status of the shop floor.
