Safety Technologies in Autonomous Decentralized Railway Control System

Abstract

Along with sophistication of society, requirements for infrastructure systems are also becoming more sophisticated. Conventionally, the infrastructure system has been accepted if it is safe and stable, but nowadays it will be required for serviceability as a matter of course. For this reason, not only expansion of the scope of the control system but also integration with the information service system has been frequently carried out. In this paper, we describe safety technology based on autonomous decentralized technology as one of measures to secure safety in a control system integrating such information service functions.
