초록

본 논문은 다관절 철도 차량의 효율성 및 안정성 향상을 위해 분산형 제어 시스템 구축 시 이더넷 기반의 Train Communication Network(TCN) 적용안을 제시하고, 해당 망의 최적 네트워크 토폴로지 구성을 위한 방법론을 제안한다. 적용된 TCN은 백본 망과 하위 망의 계층 구성을 갖고, 하위 망이 관장하는 차량의 수에 따른 전송 딜레이와 안정성을 경유 노드 수와 차량 간 케이블 수로 모델링한다. 이를 기반으로 목적 함수를 정의하고 최적해를 도출하기 위한 방법론을 제시한다. 차량 수의 정수 제약 조건을 완화하여 목적함수의 최적 실수해를 먼저 도출하고, 이로부터 최적 정수해를 탐색하는 방법을 이용한다. 수치 결과를 통해, 도출된 해의 특성을 다양한 관점에서 분석한다.

For higher efficiency and reliability of railroad trains with many electronic sensors and actuators, a distributed control system with which electronic components communicate with each other in a distributed manner via a data network is considered. This paper considers Ethernet-based Train Communication Network (TCN) for this purpose and proposes a methodology to optimize the topology in terms of transmission latency and reliability, each of which is modeled as the number of traversing backbone nodes and the number of cables between vehicles, respectively. An objective function is derived accordingly and a closed-form optimum is obtained by relaxing the integer constraint of the number of vehicles for a unit network. Then, the final integer optimum is searched around it. Through numerical evaluation, the validity of the proposed methodology and the characteristics of the resulting solutions are shown.
