철도신호시스템의 신뢰성 향상을 위한 Switched-Ethernet기반 Redundancy Architecture 구현

초록

network technologies are applied in the real-time industrial control system, and also there are several studies to apply the computer network technology in vital control system such as railway signaling systems. To deploy this computer network related studies in railway signaling systems, it has considers such as implementation costs, transmitted reliability, safety assurance technique, compatibility, and et al. The computer network protocol for railway signaling systems has an important advantage over the widely used Ethernet in terms of the deterministic characteristics. In this paper, we propose the computer network technology, especially Ethernet, for railway signaling systems.
