Abstract

A control station, a slave station, a control method of the control station, and a control method of the slave station capable of securing an evacuation time and controlling a gate to be closed are provided. A control station of an embodiment is a control station in a gate control system for controlling operations of gates. The gate control system including the control station and slave stations. The control station including: an information acquisitor and a control information transmitter. The information acquisitor acquires emergency information via satellite communication. The control information transmitter simultaneously transmits gate control information for controlling the gates to the slave stations via the satellite communication on the basis of the emergency information.

a gate controller configured to generate a signal for notifications for closing the gates when the gate control information is received by the receiver, the gate controller being configured to control the gates to be closed when a time has elapsed from transmission of the gate control information by the control station.

2. The slave station according to claim 1,

wherein the gate controller is configured to generate the signal for notifications for closing the gates when the receiver receives the signal for controlling the notification, and

wherein the gate controller is configured to control the gates to be closed when a time has elapsed from transmission of the notification signal by the control station.

3. The slave station according to claim 2,

wherein the receiver is configured to receive the gate control information for controlling the gates to be closed, where the gate control information was transmitted by the control station when the time has elapsed from transmission of the notification signal by the control station, and

wherein the gate controller is configured to control the gates to be closed when the gate control information is received by the receiver.

4. The slave station according to claim 2, wherein the gate controller is configured to transmit a closing signal of a level for closing a gate to a device which operates the gates, the gate controller is configured to transmit the closing signal in which the gate controller updates the level when the slave station receives no response from the device to the closing signal transmitted by the gate controller.

5. A method of controlling a slave station of a gate control system which comprises a control station, control centers, and other slave stations and which controls operations of gates, the method comprising:

receiving gate control information for controlling at least an associated gate of the gates from control stations via satellite communication, the gate control information having been simultaneously transmitted from the control stations to the slave station and the other slave stations in the gate control system;

generating a signal for notifications for closing the gates when the gate control information is received by the receiver; and

controlling the gates to be closed when a time has elapsed from transmission of the gate control information by the control station.

6. The method according to claim 5,

wherein generating the signal for notifications for closing the gates comprises generating the signal for notifications for closing the gates when the receiver receives the signal for controlling the notification, and

wherein controlling the gates to be closed comprises controlling the gates to be closed when a time has elapsed from transmission of the notification signal by the control station.

7. The method according to claim 6,

wherein receiving the gate control information comprises receiving the gate control information for controlling the gates to be closed, where the gate control information was transmitted by the control station when the time has elapsed from transmission of the notification signal by the control station, and

wherein controlling the gates to be closed comprises controlling the gates to be closed when the gate control information is received by the receiver.

8. The method according to claim 6, wherein controlling the gates to be closed further comprises transmitting a closing signal of a level for closing a gate to a device which operates the gates, where the level is updated when the slave station receives no response from the device to the closing signal transmitted.

9. A gate control system comprising:

a control station; and

a plurality of slave stations configured to control gate operations,

wherein the control station comprises;

an information acquisitor configured to acquire emergency information via satellite communication; and

a control information transmitter configured to simultaneously transmit gate control information to the plurality of slave stations via the satellite communication based on the emergency information, and

wherein each of the plurality of slave stations comprises;

a receiver configured to receive the gate control information which has been simultaneously transmitted from the control station; and

a gate controller configured to activate, based on the gate control information, a safety information dissemination facility to provide a notification that the gate is to be closed and, after a first time has elapsed from activating the safety information dissemination facility, to control the gate to be closed.

10. The gate control system according to claim 9, wherein the gate control information comprises:

a simultaneous notification instruction for activating the safety information dissemination facility; and

a simultaneous closing instruction to be transmitted when a second time has elapsed from transmitting the simultaneous notification instruction for controlling the gate to be closed, and

wherein the gate controller is configured to activate the safety information dissemination facility when the receiver receives the simultaneous notification instruction, and

wherein the gate controller is configured to control the gate to be closed when the receiver receives the simultaneous closing instruction.

11. The gate control system according to claim 9, wherein the control station further comprises:

an operation response signal receiver configured to receive a respective response signal to the gate control information from each of the plurality of slave stations through the satellite communication,

wherein the control information transmitter is configured to recognize a respective state of each of the gates based on whether the operation response signal receiver received the operation response signal from each of the plurality of slave stations, and

wherein the control information transmitter is configured to re-transmit the gate control information to the slave station from which the operation response signal receiver has not received the operation response signal.

12. The gate control system according to claim 9, further comprising:

a control center configured to manage the gates that are connected to the slave stations,

wherein the control center comprises;

a display device configured to display information of an opened/closed state of each of the gates managed by the control center; and

a transmitter configured to simultaneously transmit, based on the opened/closed state, a closing instruction for one or more of the plurality of slave stations to the plurality of slave stations through the control station.

13. A control station comprising:
