Flooding-proof region protection system based on ATC (automatic train control)

The invention discloses a flooding-proof region protection system based on ATC (automatic train control). The flooding-proof region protection system comprises an interlocking collecting unit, a rail-beside ATP (automatic train protection) unit, a vehicle-mounted ATP unit and an ATS display unit, wherein the interlocking collecting unit collects opening and locking information of a flooding-proof door and closing request information of the flooding-proof door from a flooding-proof door system, the rail-beside ATP unit sends mobile authorization inlet path information, protection region information and flooding-proof door closing allowing judging information to the ATS display unit, the vehicle-mounted ATP unit uploads vehicle-mounted operation data to the rail-beside ATP unit and the ATS display unit, and the ATS display unit displays the opening and locking information of the flooding-proof door, the closing request information of the flooding-proof door, the mobile authorization inlet path information, the protection region information, the flooding-proof door closing allowing judging information and the vehicle-mounted operation data. The flooding-proof region protection system has the advantage that the safe and correct state information collection and the effective and reliable flooding-proof door region protection can be realized.
