PROBLEM TO BE SOLVED: To provide a system capable of securely closing a gate of the whole object region even if the number of collected operators is insufficient when tidal wave and high tide occur. SOLUTION: A camera 4 for monitoring the surroundings on a sea side, a gate door monitoring device 5, an alarm device 6, a gate driving device 7, a water level gage 8, electronic equipment on an operation table 9, and a recorder 10 are connected with a gate controller 1 by a communication means. The gate door monitoring device 5 is provided with an image distribution device 11 and an image processing device 12. Furthermore, the image distribution device 11 is connected with a monitoring camera 13 provided per gate. In the gate door monitoring device 5, the image distribution device 11 is linked to the gate controller 1 through the image processing device 12. A motor 20 and a limit switch 21 are linked to the gate driving device 7. At least the monitoring camera 13, an alarm, and the gate driving device 7 are provided per gate. An operation table pressing and dividing device 22 is provided in a central controller 2 in a central control part B and is further connected with a remote monitoring part 24 and a tidal wave and high tide alarm system 25.
