北陸新幹線50／60Hzき電両用区間対応DS-ATCの開発

摘要

We developed DS-ATC (Digital Communication and Control for Shinkansen Automatic Train Control) for 60Hz feeding, applicable to Hokuriku Shinkansen extension project. There are three big challenges. First, the current DS-ATC system for 50Hz feeding is required to be arranged for 60Hz feeding. Second, the onboard system and the ground equipment are required to switch between signal for 50Hz feeding and that for 60Hz feeding at handover area. Third, in some areas the ground equipment is required to be compatible with both 50Hz and 60Hz feeding. We report how we overcame these challenges.%本報告では，北陸新幹線向けDS－ATCの開発について技術課題とその解決について報告した。60Hz向け信号の搬送周波数の策定，試作機による伝送の確認，異周波突き合わせ区間における信号切替等，北陸新幹線向けDS－ATCに関する基本的な開発については既に終了しており，現在実機の製作中である。
