  • 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.

  • On-line monitoring techniques for fumaric acid and succinic acid were developed by flow injection analysis (FIA). For the determination of fumaric acid, two enzymes, fumarase and malic dehydrogenase were immobilized on VA-epoxy Biosynth E3-carrier and integrated into a FIA-system with a fluorescence detector. For the analysis of succinic acid, isocitrate lyase and isocitrate dehydrogenase were also immobilized on VA-epoxy polymer support and used in a FIA system. The immobilized enzymes in two FIA systems were characterized systematically, e.g. optimum pH and temperature, inhibitory effects etc. Two FIA systems were also used to on-line monitor the concentrations of fumaric acid and succinic acid in biotechnological processes. Good agreement between on-line monitored data and off-line data measured by HPLC showed extensive application of the FIA systems in bioprocesses.

  • 산업의 발달과 인구의 증가로 인한 물 사용량 증가와 다양한 폐수들이 끊임없이 발생하고 있다. 회사나 공장들은 이러한 폐수를 처리하기 위한 하ㆍ폐수처리장의 효율적인 운전을 위하여 관리ㆍ제어 시스템을 도입하고 있는 추세이다. 본 논문에서는 김해에 설치되어 있는 축산 폐수를 처리하는 파일럿 플랜트의 공정상태를 원격으로 관리할 수 있는 모니터링 시스템을 바탕으로 퍼지와 신경망을 이용한 실시간 원격 진단 및 제어 시스템을 설계하였다. 또한 여러 경우의 고장 사례를 원격 진단ㆍ제어 시스템에 접목시킴으로써 진단시스템의 성능을 더욱 향상 시켰다. 이러한 진단ㆍ제어 시스템을 이용하여 관리자는 공정상태를 항상 모니터링 할 수 있으며, 진단ㆍ제어 시스템에서 제공하는 경고 및 제어 값을 축산폐수플랜트에 전송함으로써 공정을 보다 효율적이고 안정적으로 진단ㆍ제어할 수 있다.

  • The technological advances such as communication, sensor, and artificial intelligence lead smart factory construction. Smart factory aims at efficient process control by utilizing data from the existing automation process and intelligence technology such as machine learning. As a result of constructing smart factory, productivity increases, but costs increase. Therefore, small companies try to make a step-by-step transition from existing process to smart factory. In this paper, we have proposed a remote control system that support data collection, monitoring, and control for manufacturing equipment to support the construction of CNC cutting machine based small-scale smart factory. We have proposed the structure and design of the proposed system and efficient sensing data transmission scheme. To check the feasibility, the system was implemented for CNC cutting machine and functionality verification was performed. For performance evaluation, the web page access time was measured. The results means that the implemented system is available level.

  • In the construction project, the efforts to use IT for efficient management and improvement of productivity is gradually increasing. For instance, the cite management model with 3D CAD and RFID shows one of efforts this model define and systematize a variety of data occurred each work unit(design, material and process management information, etc). However, so far, there has been the problem monitoring the site due to the an inaccurate data and low-practice which people should input in manual. In this paper, we would like to establish the data for real time monitoring system with data inputting automatically from RTPM system and the site, and analyze the relationship between tables consist of similar data through RED Diagram.

  • 플라즈마를 이용한 반도체 이온 주입 공정(Plasma Immersion Ion Implantation)에서 이온 도즈량(DOSE) 측정은 공정 신뢰성 및 재현성 확보를 위해 중요하다. 본 연구에서는 도즈량 측정을 위해 패러데이컵과 같이 측정 장비를 챔버에 직접 삽입 시키지 않고 챔버 외부에서 이온 주입을 위한 바이어스 전극의 직류 펄스 전압 및 전류 신호 측정을 통해 실시간으로 도즈량을 추출하는 방법을 개발하였다. 펄스 전압 신호에서 전압 신호 상승, 하강 시간에 의해 발생된 변위 전류와 플라즈마 발생 소스의 RF잡음등을 제거한 후 이온 포격으로 인한 2차 전자 방출 계수를 고려하여 펄스 동작 기간 추출을 통해 실시간으로 측정하는 알고리즘을 구현하였다.

  • Cleaning process is necessary for machining parts or manufacturing finished products in the industry. Most of domestic and foreign companies are now trying to adopt environment-friendly aqueous cleaning agents instead of CFC-113 and 1,1,1-TCE which are ozone-depleting substances. However, the aqueous cleaning system has a disadvantage due to its generation of lots of waste water since the system utilizes water in cleaning and rinsing processes. Thus, it is very important that monitoring and recycling technologies of the cleaning solution and the rinse water should be introduced in the aqueous cleaning system in order to minimize generation of waste water and to maintain its cleaning performance for a quite long time. In this paper, the cleaning agents utilized in the aqueous cleaning system and cutting oils which are main contaminants were examined and analyzed. And the monitoring and recycling technologies of the aqueous cleaning system which can be employed in the industrial fields were also reviewed and evaluated.
