This paper proposes a soft-remote-control (soft-remocon) system based on EMG signals for the Intelligent Sweet Home. The proposed system is applied to Intelligent Sweet Home which was developed to help the independence living of the elderly and physically handicapped individuals. The goal of proposed system is to control home-installed electronic devices such as TV, air-conditioner, curtain and lamp in Intelligent Sweet Home using EMG signals. Features such as VAR and DAMV having good separability performance are selected for pattern classification. FMMNN is adopted as a pattern classifier. Classification results are allowed to a developed remote control module and then corresponding infrared pulses can operate home-installed electronic devices. We concluded that EMG as an input interface for home-installed electronic devices in Intelligent Sweet Home.

In this paper, we developed an outdoor augmented reality system which has remote real scences acquisition ability. The real scenes acquisition system consists of image acquisition system, tracking system, wireless data transceiver and power supply. Tracking system that consists of Tans Vector and RT-20 measures a position and attitude of the CCD camera that attached at the remote control helicopter. Wireless data transceiver system is utilized for data transmission of remote system that of attitude, position information, andreal scenes data that acquired by the CCD camera. Maximum propelling power of remote control helicopter is 15Kg, so we used 7.2V li-ion cell as a power supply for system minimize. As the results of experiment, the developing system presented application possibility of remote information acquisition system such as construction simulation & estimation, broadcasting, tour guide.

In this paper, a communication method is proposed for the development of a main engine remote control system. The main engine control system compriese three subsystems such as RCS (Remote Control System) BCS (Bridge Control System) and SS (Safety System), Thus it is required to exchange data each other among these subsystems. The communication method has simplified hardware through the minimization of communication components where the interrupt method are employed for receiving and the polling method for transmitting. We discuss a methodology of using a ring buffer for data storage physically which has two buffers virtually for the effective use of memory. This communication method presents a good performance in the system which has rather small numbers of communication data.

기존 웹 기반인 시스템 관리 소프트웨어 솔루션들은 시간적, 공간적 제약을 갖는다. 그리고 오류 메시지에 대한 불확실한 통보와 실시간 지원요구 및 긴급조치가 어렵다는 문제점들을 갖는다. 이러한 문제들을 해결하기 위해서 모바일 통신기기를 이용하여 원격시스템을 관리 및 모니터링하고 즉각적으로 원격지의 시스템을 제어할 수 있는 무선 원격제어 시스템을 설계 및 구현하였다. 구현된 무선 원격제어 시스템은 이러한 문제의 해결뿐만 아니라 보안의 문제도 갖고 있다. 그러므로 본 논문에서는, 무선 원격제어 시스템을 위한 보안 문제에 초점을 맞추어 진행하였으며, 설계한 보안기능은 사용자에 대한 모바일장비 사용자 인증과 대상 시스템 접근제어 기능을 갖도록 하였다. 이러한 보안 기능에 대한 안전성 검증을 위하여 각 단계에 대한 모든 가능한 상태를 표현할 수 있는 CPN(Coloured Petri Nets)을 도입하였다. 그리고 본 논문에서는 CPN 기반의 상태 불변식으로 안전성을 검증하였다. 제안한 보안 기능의 CPN 표현과 분석방법은 차후에 다른 서비스 모델의 설계와 검증에 유용한 방법이 될 수 있다.

This paper suggests the vehicle remote control on the basis of Smart Phone. In general, most smart phone is mounted with G-sensor to control the motion. G-sensor is able to control several directions and movements of velocity along with X, Y, and Z axis. To access remote location and data system, we can also utilize Wi-Fi communication as well as bluetooth communication. In this study, we propose the scheme that is the car management application by remote control via real-time monitoring on mobile device for user convenience.

A teleoperated manipulator system has been developed for remote handling of the spent fuel bundles. A heavy-duty power manipulator with high reduction ratio joints is used for the slave manipulator in the developed system since the handling tasks of the spent fuel bundles need power. Also, the universal type master manipulator, which has force reflecting capability, is used for precise remote manipulation. The power manipulators so frequently occur the control input saturation that the precise control performances are not achieved due to the windup phenomenon. An advanced bilateral control scheme compensating for the saturation is applied to the teleoperated manipulator system. The validity of the developed system is verified by the grid cutting and fuel transportation tasks from the mockup spent fuel bundle.

In this paper, the power system automation based on CAN communication protocol is introduced. Along with digitalization of electrical device, the various on-line services such as remote control, remote monitoring, remote parameter setting, fault data recording and remote diagnostic have been realized and become available. Therefore, it is necessary for those electrical devices to have real-time and reliable communication protocols. Author proposes DNPC(Distributed Network Protocol with CAN) which is proper to the power system SCADA (Supervisory Control And Data Acquisition) and DCS (Distributed Control System). The physical and datalink layer of DNPC protocol consists of the CAN2.0B which has the real-time characteristics and powerful error control scheme. As the transport and application layer, DNP3.0 is adopted because of its flexibility and compatible feature. Using the DNPC protocol, the power system automation is realized.
