Abstract
Electric heat tracing 시스템은 플랜트 내 각종 배관의 온도를 관리하는 시스템이다. 본 논문에서는 electric heat tracing 시스템을 통합적으로 감시하고 제어하기 위한 TESCON(: TEmperature Sensing and CONtrol) 시스템을 제안한다. TESCON 시스템에서 디바이스간의 정보 교환은 Zigbee 네트워크 기반의 무선 방식으로 이루어진다. TESCON 시스템의 성능 분석을 위해 컴퓨터 시뮬레이션을 수행하였다. 테스트베드를 통해서도 비슷한 결과를 얻음으로써 TESCON 시스템의 유효성을 입증하였다. 또한, 계층적 트리 토폴로지를 기반으로 하는 네트워크 분할, 채널 재사용, 프레임 집약 기법 등을 적용한 시스템 확장 방안도 제시하였다. An electric heat tracing system manages the temperature of pipes used in a plant. We propose a Zigbee-based wireless system so called the TESCON(: TEmperature Sensing and CONtrol) to monitor and control the electric heat tracing system in an integrated way. Simulations have been done to analyze the performance of the TESCON system. The performance of the TESCON system is validated by obtaining similar results via testbed operation. We also suggest an extension method of the TESCON system based on the hierarchical tree topology by adopting techniques such as network partition, channel reuse and frame aggregation.
