An Over Current Relayng algorithm using 80c196kc micro processor was realized in this paper. This OCR Algorithm was verified with simulated fault signal. The fault signal was made by EMTP and realized by DOBLE to compare H/W test with S/W test. This simulations showed similar result between H/W and S/W test.

다기능 휠체어 시스템의 제어부인 80C196KC를 사용했으나, fuzzy 알고리즘을 적용하는데 있어서 여러 가지 문제점(속도, 연산, 외부장치 등) 때문에 구현1차는데 상당한 어려움이 있었다. 이를 해결하기 위해 20MIPS의 속도인 TMS320F240의 프로세서를 사용하였으며 이로 인해 발생하는 문제점을 거의 해소시켰고, 퍼지 알고리즘을 효율적으로 적용할 수 있었다. 본 시스템의 구성은 주제어기로 퍼지 제어 알고리즘을 사용하여 조이스틱을 제어시켰고, 2개 encoder를 입력을 받아 휠체어 회전수를 이용하여 제어시켰다. 휠체어 모터로는 BLDC(Brushless DC) 모터를 사용했으면, BLDC전용 드라이브단을 이용하여 모터를 구현시켰다. 그리고 3개의 초음파 센서를 부착하여 장애물 회피를 시도하였다. 초음파센서의 효율적인 사용을 위해 스텝 모터(Stepping Motor)와 마이크로 컨트롤러로 PIC을 사용하였다. 본 논문의 실험 결과에서는 이전의 제어기(80C196KC)보다 현저히 성능 면에서 향상되었고, 부수적인 외부장치 처리면에서도 상당한 차이를 볼 수 있었다

본 논문에서는 TCP/IP 기반에서 웨이블릿 변환과 인터넷을 이용 원거리에 있는 Device를 PDA로 제어하는 영상감시 솔루션에 대해 연구하였다. 우선 서버는 카메라를 이용하여 영상을 획득하고 획득한 영상에 대해 2단계 웨이블릿 변환을 한 후, 인터넷을 통해 Client(PDA)로 전송한다. PDA는 수신한 프레임만을 가지고 역 웨이블릿 변환을 하고 사용자에게 영상을 보여주게 된다. 카메라는 스텝 모터와 마이크로프로세서 80C196KC에 의해서 컨트롤되고, 사용자는 서버에서 보내는 영상을 PDA를 이용해서 감시한다. 그리고 PDA를 이용 원거리에 있는 서버 80C196KC에 제어 신호를 보내고 자신이 원하는 영상을 감시할 수 있다.

In this study, we used a 16-bit microprocessor, 80C196KC for a control part in order to develop a multi-functional wheel-chair system, and implemented a joy-stick to control this system. For the complete system, we used a commercial electromotive wheelchair as a basic plant, and applied an encoder to get the rotating number of the motor to transfer data to the MCU to control the motor. We used PWM (Pulse Width Modulation) method to control the wheel-chair motor where a H-bridge circuit was configured. We used the fuzzy control algorithm for the operation of DC motor, which was attached to the electromotive wheelchair and manipulated following the change of the joystick position while a user was controlling the Joystick. He also could control the speed and direction of DC motor as well as control position information.

This paper presents the design of intelligent moving machine control system using a real time speech recognition. The proposed moving machine control system is composed of four separated module, which are main control module, speech recognition module, servo motor driving module and sensor module. In main control module with microprocessor(80C196KC), one part of the artificial intelligences, fuzzy logic, was applied to the proposed intelligent control system. In order to improve the non-linear characteristic which depend on an user's weight and variable environment, encoder attached to the servo motors was used for feedback control. The proposed system is tested using 9 words lot control of the mobile robot, and the performance of a mobile robot using voice and joystick command is also evaluated.

Switched Reluctance Motor(SRM) offers the advantages of simple and robust motor construction, high speed and high efficiency over a wide operating range of torque and speed, excellent controllability. However SRM has the disadvantages of high current harmonics, and low power factor because the required output of speed and torque is produced by the discontinuous and loss of power system, and brings about the incorrect operation of electronic system. This paper deals with an energy efficient converter fed SRM system with the reduced harmonics and improved power factor. The validity of the proposed scheme is verified via experiments. We are implemented the proposed control system using 80C196KC micro-controller.

In this paper. we present a new method for monitoring of ECU's self diagnostic signals of vehicle without wire. In order to measure the ECU's self diagnostic signals, the interfaced circuit is designed to communicate ECU and designed terminal according to the IOS, SAE regulation of communication protocol standard. Micro-processor 80C196KC is used for communicating ECU's self diagnositc signals and the results are sent to the wireless terminal and PC monitoring system. Wireless terminal is also developed by 80C196KC, LCD, RF module, and keypad. The command from the keypad is sent to ECU through RF module and the result show on the Graphic LCD in real time. Software on PC is developed to monitor the ECU's self diagnostic signals using the Visual C++ complier in which RS232 port is programmed by half duplex method. The algorithms for measuring the ECU's self diagnostic signals are verified to monitor both ECU and portable terminal state. At the same time, the information to fix the vehicle's problem can be shown on the developed software. The possibility for remote measurement of ECU self diagnostic signal is verified through the developed systems and algorithms.
