  • 이 논문에서는 SNMP를 이용하여 윈도우 환경에서 동작하는 실습실의 PC를 관리하기 위해 MIB을 정의하고 이를 모니터링 및 제어하는 관리 시스템을 설계하였다. 제안된 시스템은 PC의 상태를 제어하는 제어 시스템과 실시간 모니터링 및 프로세스 제어를 담당하는 모니터링 시스템으로 구성된다. 제어 시스템의 경우 PC의 구성 정보 갱신 및 설정과 장애 발생시 이를 백업/복구를 담당한다. 모니터링 시스템은 초중고 생의 PC를 모니터링하고 실시간으로 실행중인 프로세스를 제어 및 새로운 작업을 실행시키는 기능을 갖고 있다. 이 시스템은 교사가 초중고의 PC 실습실에서 교육중 발생할 수 있는 학생들의 프로그램 사용을 통제하고 모니터링함으로써 교육의 효과를 높일 수 있다.

  • The wastewater reclamation and reusing system has been rising as an alternative of water resource exhaustion that the whole world is experiencing. In order to be able to bring about improvement of the existing wastewater reclamation and reusing system, this research has developed of Conversion-Human Machine Interaction (C-HMI) based real-time control and monitoring system such as a sensor module and gate module, web monitoring system. This system was communication almost-error-free in various environment and situation. As a result, we have achieved our goal that has to doing work correctly as a sensor and gateway module that communication error is less than 0.2% throughout the embodied system and add that it can be easily controled and configured as an interface equipment to a complex sensor of water quality. According to this, the construction of a database capable of analyzing and assessing collection, storage and various elements of reliable water quality and flow rate data can be possible.

  • Mobile computers can process large amounts of data at high speeds, and it is feasible and easy to implement a remote monitoring system utilizing mobile computers. Because of their portability and convenience, these computers have been employed in various research areas to develop such monitoring systems. Existing monitoring system is a bit difficult to real time monitoring the scattered offshore facilities. So this paper compensate the existing system by using mobile computers such as a tablet PC-based monitoring system. Also, the scattered offshore facilities can be monitored in real-time through the tablet PC. The developed monitoring system is a fully Internet-based monitoring platform that enables one to monitor and control remote oceanic applications at any time and any place where it is possible to access the Internet. It can be applied to many oceanic applications as well as the unmanned systems and remote monitoring systems on land.

  • On the satellite communication system, conventional key issues of control have been focused on the attitude and orbit control, monitoring and control of communication payload such as IOT(In-Orbit-Test) and CSM(Communication System Monitoring) and so on. As the vulnerabilities are being increased on the satellite communication network, security services are required to protect it against security violated attacks. In this paper, a security architecture for satellite communication network is presented in order to provide security services and mechanisms. Authentication protocol and encryption scheme are also proposed for spacecraft command authentication and confidentiality.

  • This paper presents a position control system for a linear induction motor(LIM) with cage-type secondary using direct thrust control(DTC). Also it presents a virtual instrumentation(VI) system for LIMs performance monitoring. The VI is designed using the graphical programming language LabVIEW and is capable of performing measurement functions, including data acquisition, display, and analyses at the same time. This paper reports the LIM's responses of the thrust, current, speed, and flux measured by the proposed monitoring system.

  • The traffic of tug/barges which are carrying construction materials, large plants for harbor development, or offshore structures has recently increased in the coast of Korea. The west and south coast of Korea are always congested due to a lot of islands and traffic concentration. Specially tug/barges have higher probability of marine accidents due to their bad maneuverability than others. Considering the operational circumstance and maneuverability, this study was to develop a wide-area monitoring and control system for tug/barges in the coastal area of Korea. The system was made in the form of three program modules i.e. navigation analysis program module, monitoring and control program module, database module. And seven functions were programmed to monitor and control the tug/barges efficiently. These are ship information search, tug/barge information and track management, designated area and safe navigation zone management, fairway management, accident data management, warning of danger, safety information management.
