Abstract
Automatic Train Control (ATC) in the railway signalling system is required high safety, high availability, reduction of unit, energy saving and cost reduction. This paper described the resources communization redundancy of the ATC system that shared the redundant units in preparation for common use units in order to accommodate with this issue by keeping safety and availability in the same level of conventional ATC. It was evaluated on N+2 redundant system which established 2 spares for the common use system N piece in transmission division. It was done the safety evaluation of the N+2 redundant system by way of hazard analysis of FTA method and safety issue was confirmed by FMEA. The new redundant system concludes that 19% of downsizing and 36% of the energy saving are surely possible.
