초록

본 논문에서는 지그비(Zigbee) 센서 네트워크를 기반으로 하여 다중노드를 실시간으로 감시하고 진단하며, 다수의 다양한 센서로부터 발생하는 데이터를 통합적으로 제어할 수 있는 진단 및 통합 관리시스템을 제안하였다. 제안된 시스템은 대상시스템의 상태를 효율적으로 진단하고 제어하기 위해서 원격지의 센서들로부터 유선 및 무선으로 수집된 데이터를 실시간으로 서버에 전송하고, 이를 분석하여 필요한 동작이 실행되도록 설계되었다. 다수의 센서들은 클러스터 형태로 구성되고, 센서노드는 획득된 데이터에 대한 전송 및 제어 기능을 수행하며, 각 센서 노드로부터 수신된 데이터를 구분하여 처리한다. 구현된 시스템의 성능을 평가하기 위해서 전송거리에 따른 최소 전송 지연시간과 다수의 센서로부터 발생된 데이터 손실률 등을 측정하였고, 그 결과 우수한 성능을 보임을 확인하였다.

In this paper, a multi-node real-time diagnostic and management system based on zigbee sensor network is proposed, which is to monitor and diagnose multiple nodes as well as to control the data generated from the various multiple sensors collectively. The proposed system is designed to transmit the collected wireless and wired data to the server for monitoring and controling efficiently the condition for multi-nodes by taking the corresponding actions according to the analysis. The system is implemented to make it possible to manage the sensor data by classifying them, of which data are issued from the clustered sources with a number of the remote sensors. In order to evaluate the performance of the proposed system, we measure and analyze both the transmission delay time according to the distance and the data loss rate issued from multiple sensors. The results shows that the proposed system has a good performance.
