MMI 시스템은 제철 공정에서 발생되는 다양한 데이터를 조업자에게 쉽고 빠르게 전달하기 위해, real time operating system에서 동작하는 제철공정의 주된 제어 프로세스와 인터페이스 한다. 따라서 MMI 시스템은 제철 공정의 주된 제어 프로세스와 ethernet network을 통해 공유 데이터들을 통신하도록 개발되고, MMI 시스템은 M/S window operating system과 DDE(Dynamic Data Exchange) 라이브러리 환경을 기반으로 개발된다. 수 개의 MMI client PC와 1 개의 MMI server로 구성되는 MMI 시스템은 MMI client들 사이의 공유 데이터가 동기화될 수 있도록 최적 packet 양을 도출하고, 신뢰성 높은 데이터 전송을 위한 특별한 데이터 핸들링 방법을 사용한다. MMI 시스템은 GUI(Graphic User Interface)를 사용하여 조업자에게 친숙한 window 화면을 제공하므로, MMI 시스템의 화면 수정, 첨가 및 삭제가 비용 부담없이 용이하게 진행되므로, 기존 제철 공정에서 사용하던 OCP(Operating Control Panel)들이 MMI 시스템으로 대체되고 있다.

This paper presents a prototype of visualization MMI of the Power System Phenomenon, specially synchronous machine dynamics and frequency deviations of power system for KEPCO's Enhanced Power System Simulator(KEPS)[1]. And some visualization designs of the Power System Phenomenons such as voltage stability, transient stability, SSR, Line overflow, and voltage deviations are presented. The prototype MMI has included the animations & 3D graphics presentations for synchronous machine rotor deviations and frequency deviations. So, a user can intuitively acquire the basic concepts of the power system oscillations. Finally, it will be scheduled to development of the various visualization MMI of the power system phenomenons for development and installation of KEPS.

We have developed Virtual Reality Simulator MMI for operator training. MMI communicates with server model and client PC through OPCServer. We used Dataplant for Soft Panel and Simdiagram which shows more sophisticated and reality colors. We used vector method for MCR images instead of conventional bit-map method to protect images during zoom in and zoom out. VBScript and Components were used for real movements and images of instruments. VRMCR panel is consisted of 12 groups and designed to accommodate user's convenience.

It is necessary to develop graphic MMI (Man-Machine Interface) for the maximum utilization of our installed ADS (Automated Distribution System) for which an operator types and executes string commands. Considering the restrictions and characteristics of the installed ADS and the data for modelled distribution lines, we calculated the time of periodic data acquisition for large number of points. And we presented the performance and characteristics of the graphic MMI system which will be developed and which will facilitate SCADA(Supervisory Control And Data Acquisition) functions.

MMI (Man Machine Interface) is the system that monitors the operating condition of the ATP/ATC/ATS systems and receives defined information from ATP/ATC/ATS systems through the interface with On-board systems. Based on the data from the ATP/ATC/ATS system, MMI can display the information and status of the train to secure safe operation. It is possible for the display mode and quantities of MMI to be improved by the customer's demand, and it can be designed as the same structure of existing devices for the driver. The ERTMS is Regular Safety Standards of high-speed railroad. It is fundamental structure of European Rail Control System which train control, safety and operate facilities. In this paper, I study requirements of ERTMS form which design function each section of MMI and application at ATP/ATC/ATS combined Train Constrol System.

In order to access to the Business Computer (B/C), the Process Computer(P/C), and the Database Server in one terminal, the Open Man Machine Interface (MMI) System has been developed. The testbed to develop the interface functions for B/C, P/C, DB server, and CCD camera were constructed, which consisted of Workstations and Personal Computers (PC). Graphic display programs Monitoring the process states of Tandem Cold Mill plant were developed using four Graphic User Interface tools: InTouch, FIX32, Open Interface Environment, and ILOG Views. With regard to the CPU utilization and response delay required to open new display, the performance tests have been carried out on each MMI platform.

In accordance with increase, if electronic power demanded, more efficient supervisory control of distribution system will be required. This study contains development of MMI(man-machine-interface) system with GUI(graphic-user-interface), for the automatic power distribution system. The main function of MMI system is to edit network of power distribution and to management of data base for network. The GUI function of MMI system enables more efficient management of power distribution system.

본 MMI를 통해 개발된 웨스팅하우스 950 Mwe 최적 NPA는 기존의 단순한 Point Kinetics 모델이 아닌 정교한 3D 실시간 노심모델과 RETRAN 코드를 기반으로 하는 실시간 NSSS 열수력 모델(ARTS)이 통합된 모델을 갖추었으며, 해당형식 발전소(Westinghouse 3 Loop PWR Plant)의 여러 가지 과도사고를 실시간으로 정상, 비정상, 비상운전 모의할 수 있도록 개발되었다. 이 NPA는 기존의 유닉스 환경이 아닌 일반 범용 PC 서버와 윈도우즈 환경(Operating System)이라는 개방형 서버-클라이언트 구조를 채택하여 저렴하고 실용적인 시스템을 추구하였다. 다양한 색상 표현이 가능한 GUI 툴을 이용하여 노심 내부의 3D 열중성자 속 분포등 사용자가 직관적으로 알 수 있는 쉬운 구성의 클라이언트 제어 시스템을 개발, 연계하여 사용자의 편의성을 도모하였다.
