Abstract

Due to global warming and increased energy costs around the world, interests of energy saving and efficiency have been increased. In particular, forging factories need methods to save energy and increase productivity because of needing amounts of energy uses. To solve the problem, we propose a system, which includes collection, monitoring, and analysis process, to monitor energy uses each facility in realtime based on the IoT devices. This system insists of worksheets management, facility/energy management, realtime monitoring, history search, data analysis through connecting with existed ERP/MES Systems in manufacturing factories. The energy monitoring process is to present used energy collected from IoT devices connected with installed gasmeter and wattmeter each facility. This system provide the change of energy uses, usage fee, energy conversion, and green gas information in realtime on Web and mobile devices. This system will be enhanced with energy saving technology by analyzing constructed big data of energy uses. We can also propose a method to increase productivity by integrating this system with functions of digitalized worksheets and optimized models for production process.

전 세계적으로 지구 온난화 및 에너지 비용 상승으로 인해서 에너지 절감에 대한 관심이 증가하고 있다. 특히, 단조 공장들은 에너지를 많이 사용하기 때문에 에너지를 절감하면서 생산성을 향상시키는 방법에 대한 연구가 필요하다. 이러한 진입을 위한 한 가지 해결책으로 IoT 기반으로 각 설비의 에너지 사용량을 실시간으로 파악할 수 있는 시스템을 제안한다. 본 시스템은 생산 공장에서 사용하는 기존 기업자원관리시스템과 생산실행시스템과의 연동으로 작업일지 입력/관리, 설비/에너지 관리, 실시간 에너지 모니터링, 이력 검색, 데이터 분석 등으로 구성된다. 중심이 되는 실시간 에너지 모니터링 프로세스는 각 설비별로 기존 설치되어 있는 가스계량기와 전력계에 IoT 디바이스를 연결시켜 데이터를 실시간으로 수집한다. 그리고 수집된 에너지 사용량을 웹 또는 모바일에서 실시간으로 화면에 표출한다. 본 시스템의 장점은 생산 공정 단계에서 설비별 도시가스 및 전력 에너지 사용량의 변화, 사용요금, 에너지 환산, 온실가스 등의 정보를 웹 기반에서 실시간으로 파악할 수 있다는 것이다. 향후, 빅 데이터 기반에서 에너지 사용량을 수집하여 생산 공정별로 에너지 사용량을 분석함으로써 제품 생산 소요시간을 최소화할 수 있는 에너지 절감 방안 수립에 사용될 수 있다. 또한, 모바일 작업일지시스템과 생산 공정 최적화 모델과 융합하면 에너지를 절감하면서 생산성을 향상시키는 방안이 마련될 수 있다.
