Nowadays, the Laser image is used to realize multi-media show for events, an advertising media and 3D simulation, realization of video image and so on. It is a hot issue to realize the laser image like computer graphic image. The image used in laser projector is vector graphic image that is described by linking point to point. A computer makes this continuous vector graphic images so that the image shows as an animation. A control signal converted by a computer makes the laser projector draw image. Two motors and universal joint are used to realize 2D laser image in this study. Developing a controller applied Look-ahead algorithm and software to interface with personal computer, This study is the chief aim of improving difference of moving velocity that is appeared from edge of vector graphic image and disparity of graphic density.

This paper presents a Windows graphic developed by the authors for the education and training of power system. Object-oriented programming is a major trend in computer software because it increases flexibility of large-scale software systems. An efficient platform for power system simulation applications has been proposed. This paper presents an intuitive Windows-based program for the power system analysis. The advantages of the object-oriented approach are demonstrated with an implementation of the graphical program. It provides a graphical interface for designing the one-line diagram of the bus and analyzing the output of the simulations. A graphical editor to visually edit the power system, diagram, results processing and exporting and graphic presentations.

This paper presents a methodology for developing the graphic simulator for a robotic workcell. The Petri Net model is applied to described the system state and the workcell simulation is performed by the event scheduling approach of the model. For the graphic display of simulation process, the information of the workcell resources are stored in hierachically-structured data_babe, and the geometry of the resources is described by robot modelling, component modelling, and world modelling.

This paper presents the development of the graphic simulator for an assembly workcell. The assembly workcell consists of two PUMA 560 manipulators, a conveyor belt system, a work table, and a vision sensor. In this study, the Petri Net theory is applied to model the assembly workcell and to construct the simulator. The event scheduling approach is used to simulate the cell. In order to show the graphic display of the simulation process, robot modelling, component modelling, and world modelling are included. The developed simulator is used to display the transition of the system state during the simulation. It is also used as a tool in selection the best resource states by studying the performance of the system as the resource states are changed.

한국전력공사 전력연구원은 10년간의 시뮬레이터 개발 경험을 바탕으로 Windows(NT)환경의 시뮬레이터 개발 툴인 Powersim을 독자적으로 개발하고 이를 이용하여 화력발전소 DCS(Distributed Control System) 검증용 시뮬레이터를 개발하고 있다. PowerSim은 GMB(Graphic Model Builder)를 갖춘 국내 최초의 시뮬레이터 개발툴로 다양한 발전소 기기모델과 강사조작반기능을 갖추고 있다. PowerSim은 완벽한 GUI (Graphic User Interface)환경을 지원하여 User가 Icon Drag 방식으로 시뮬레이션 도면(SimDiagram)을 그리면 그래픽 에디터에서 출력된 각종 기기의 접속상태를 나타내는 Netlist를 변환기가 처리하여 기기의 연결상태를 정규화하고 Scheduler는 기기모델(일종의 Subroutine)을 Netlist에 맞게 Scheduling하여 Executive에서 실행 가능한 형태로 만드는 모든 과정이 자동화되어 있다. 따라서, 개발자는 발전소 P&ID(Pipe and Instrument Drawing)에 기초하여 Simdiagram을 그리고 발전소 데이터를 입력하는 것만으로 실시간 시뮬레이터를 구현할 수 있다. 본 논문에서는 PowerSim의 개요와 GMB(Graphic Model Builder) 및 강사조작반에 적용된 GUI 환경과 실시간 Executive에 대해 다룬다.

Interactive Graphic Robotics Integrated Programming(IGRIP) can handle various types of robot models and can exchange graphic or numerical data easily with other CAD software. In a cutting process of shape-steels, however. IGRIP is inconvenient because the users must generate all the tag points manually. In this study we developed an automation program module in order to generate the tag points automatically in IGRIP This program can read and analyze the macro data containing the information for cutting processes of shape-steels and can generate automatically the parts, the devices, the tag points and the Graphic Simulation Language(GSL) program files useful in IGRIP.

The remote operation of the Advanced Spent Fuel Conditioning Process (ACP) is analyzed by using the 3D graphic simulation tools. The ACP equipment operates in intense radiation fields as well as in a high temperature. Thus, the equipment should be designed in consideration of the remote handling and maintenance. As well as suitable remote handling and maintenance method needs to be provided. To provide such remote operation technology, we developed the graphic simulator which provides the capability of verifying the remote operability of the ACP without fabrication of the process equipment. In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in a computer, not in a real environment. In this way the graphic simulator can substantially reduce the design cost of the remote operation process and the equipment. Also it can provide new operation concept that is more reliable, easier to implement, and easier to understand.

This paper discusses the development of an interactive and graphic software for the education and training of power system operation and control, especially for students and beginners. This software has a lot of functions for users to simulate the power system operation and control with ease. These functions included in this software are followings. First, this software includes a Graphic User Interface (GUI) - which contains interactive simulation scheme, Windows dialog box, graphic representations, and graphic icons - so that users can handle the software in user-friendly environments. Second, it uses a graphic editor so that users can easily edit the one-line diagram of the power system. Third, it prepares a database system so that users can manage the power system data for simulation easily. Fourth, the application modules included in the software are the Economic Dispatch (ED) and the Automatic Load-Frequency Control (ALFC). These application modules are designed as independent modules. Using the ED module, users can understand the basic concepts of the ED with ease. And using the ALFC module, they can easily acquire the basic understanding of the response of the ALFC between the two-area systems. The proposed software is tested on both the 16 bus and the two-area sample system. The test has confirmed the functions of the developed software. It is anticipated that the software will be useful for the education and training of power system operation and control for the power engineering study at university or for the training of the beginner at power industry.
