Abstract: In order to meet the demand of centralized control of CTC system in automatic block sections of universal speed railways, and effectively reduce transformation costs, this paper proposes to use computer interlocking and CTC equipment to realize remote control of section occupancy logic check equipment combined with relay-based logic check circuit for sections.

Key words: relay, logic check of sections, CTC centralized control mode, remote control
