Abstract

This paper presents the design and implementation of MIB for SNMP-based PLC system which is applicable to communication for railway vehicles. The proposed MIB has four nodes which are "Basic Information", "Configuration", "Stats", and "Alarm." The essential peripheral functions for "Alarm" to improve the performance of PLC are deyised. ACF is for auto connecting devices without intervention of the user. DEC is for checking the loss of data and the presence of error. DLPF is for preventing the loss of data and error To evaluate the proposed system, the experimental set-up is developed and the experiments are successfully carried out. The conclusion points out that the suggested MIB contributes the betterment of the conventional PLC systems.

철도차량 간 통신에 적용 가능한 SNMP기반 전력선 통신 시스템의 운영 정보베이스(MIB)의 설계 및 구현에 관한 연구로, "Basic Information", "Configuration", "Stats", 그리고 "Alarm"의 네 가지 노드를 갖는 MIB를 정의하고 구현한다. 특히 통신 성능의 향상을 위한 "Alarm"운용 함수들로서 사용자 간섭 없이 장비와의 자동 연결을 가능하게 하는 ACF, 데이터 손실과 에러의 유무를 검사하는 DEC, 그리고 에러를 포함한 데이터의 손실을 방지하는 DLPF를 정의하고 구현한다. 제안된 MIB의 평가를 위해 전력선 통신 실험 장치를 만들어 실험을 수행한다. 제안된 MIB를 갖는 전력선 통신 시스템은 종래의 것을 개선하는데 기여한 바가 있다.
