AUTOMATIC BLOCK SYSTEM USING RELAY LOGIC

摘要

The present invention provides an automatic block control system using relay logic. An automatic block control system using relay logic according to the present invention, may comprise: track circuit unit for obtaining track occupancy information in the magnetic block section; a control relay unit for controlling block signal and Automatic Train Stop (ATS)/Automatic Train Protection (ATP) based on indication information for a front block section and the obtained track occupancy information; a frequency transmitting unit which receives the indication information from a front block section, and transmits indication information of the magnetic block section to rear block section, and transmits failure information and the track occupancy information to an adjacent station, and is equipped with a dual power supply unit. The dual power supply unit comprises main power supply unit and sub power supply unit which converts an inputted AC power to DC power for the frequency transmitter only, and outputs it; and a detection relay unit which applies the AC power to the sub power supply unit, upon failure of the main power supply unit, and outputs a failure state information outward.
