Safety Guarantee Method of Network-based Interface for Signaling Systems

초록

The links between controlling equipments for railway signaling have some problems on maintenances and repairs because the way of linking is the point-to-point communication. Railway advanced countries are trying to study and develop the way of linking signaling systems by networking them [1][2]. To apply industrial networks to railway signaling systems, the network of railway signaling systems is determined to be developed by Ethernet-based protocol [3]. Ethernet application to industrial controlling systems was impossible because the real-time requirements were not satisfied owing to the random characteristics, but the recently advanced switched Ethernet enable the Ethernet technology to be applied to industrial controlling systems [4]. In this paper, we confirm the performance efficiency of the proposed network-based interface with redundancy architecture including the algorithms for detecting faults and its recovery.
