DAS(Data Acquisition System) as a ground support equipment has played a critical role in proving the status of ready-to-fire of a rocket system before launch. But it is hard to implement and place a real-time measuring system in a control room at a long distance from the vehicle. In this paper DAS is introduced by being located at the LEC(Launch Equipment Container)[1], 50 meters away from the rocket and connected to remote monitoring system via fiber optics with TCP/IP protocol by means of client/server algorithm. Therefore real-time data acquisition and storage are guaranteed and a convenient and useful MMI (Man-Machine Interface) can be developed.

The dissertation is based on the 'remote monitoring control system' for a water desalination plant which changes seawater into safe clean drinkable water. The system is operated and supported by a satellite link which can be easily handled and monitored by any professional. Therefore the system can be operated from any given location. The design allows it to function on islands that have frequent and severe water shortages via the satellite from the main sector. It shows the specific details for the main provision on building the remote monitoring control system for the water desalination.

In this paper, remote control and surveillance monitoring system of HID street-lamp using low-cost type of Zigbee communication module was developed. A plurality of capacitors with different capacity are attached to magnetic ballast for HID lamps. Changes in the amount of illumination can be adjusted by the changes in capacity so that the electric energy can be reduced. In Zigbee communication module, a ATmega128L microprocessor is used and in main CPU, ARM9 Core is used to construct a low-cost smart system. In surveillance monitoring systems, the system was configured to remote monitoring of presence of error in the lamp abnormalities, the status of leakage current and abnormalities of ballasts and capacitors and the validity of the proposed empirical experiment was confirmed.

Many industrial equipments use RS-232C interface. But Ethernet using CSMA/CD was widly spread recently. This interface is not compatible with RS-232C and requires PC based system. So In this Paper, We decribe a Internet control and monitoring system that control and watch plants without PC. We developed IP controller consisted of microprocessor and NIC and monitoring system using VC++ and SQL database. The protocol used this system is UDP/IP because it is applicable for real time system.

The related industrial technologies are also being developed in medicine, education, the military, transportation, process management, security management and information technology industries due to a rapid progress in telecommunications technology. The supervisory remote control system is based upon telecommunications technology. The supervisory remote control systems are used in various ways such as city gas, water supply and drainage, environment, power, communication and device control fields. The supervisory remort control system became a solution with complex systems and important technologies in electricity, city gas filed that require safety management skills. The supervisory remote control system as a special technology has a lot of practical applications. In this paper, Let me examine the present status of remort control system applications and present development plans and alternatives in city-gas industrial technology.

URC(Uniform Resource Identifier) 로봇은 기존의 로봇 자체에서 처리하던 기능을 네트워크를 통하여 외부로 분산시켜 외부의 센싱기능과 프로세싱 기능을 활용하여 효율적으로 구동하기 위한 것이다. 즉 많은 파워가 요구되는 센싱 기능이나 프로세싱 기능을 외부에 있는 서버를 활용하여 서비스를 제공함으로써 간단한 로봇으로도 고도의 서비를 제공이 가능토록하여 가격 경쟁력을 갖도록 하기 위함이다. 본 논문에서는 URC 로봇을 원격에서 모니터링 및 제어가 가능하도록 웹 서비스 기술을 임베디드 시스템 환경에 맞게 최적화하였다. 서비스는 인터넷 기반의 SOAP 프로토콜을 통하여 교환되는 XML 기반 메시지를 통하여 다른 응용 에이전트들과 직접적인 상호작용을 지원함으로서 이기종간 호환 및 표준 플랫폼을 지원할 수 있다. 본 논문에서는 URC 시범서비스 참가 로봇인 네토로(한울로보틱스)에 본 연구결과를 적용하여 기능 및 안정성을 검증하였다.
