Abstract
A safety system according to the present invention includes an on-ship system which is provided on a ship and a land system which is provided on land. The on-ship system and the land system each obtain, from a safety detection device and a safety maintenance device which are provided on a ship, data which has been detected by the safety detection device and a signal which indicates a state of the safety maintenance device, and, on the basis of the obtained data and signal, transmit to the safety maintenance device a control signal for controlling the safety maintenance device.
Claims7
A safety system comprising:
- an on-ship system that is provided on a ship;
- and
- a land system that is provided on land,
- wherein the on-ship system includes
- a safety detection device and a safety maintenance device for preventing disasters occurring in the ship, that are provided on the ship,
- a first acquisition unit that acquires information detected by the safety detection device and information indicating an operation state of the safety maintenance device,
- a first control unit that controls an actuator included in the safety maintenance device, and
- a communication unit that communicates with the land system, and
- the land system includes
- a second acquisition unit that acquires the information detected by the safety detection device and the information indicating the operation state of the safety maintenance device through the communication unit, and
- a second control unit that outputs a control signal for controlling the safety maintenance device to the safety maintenance device through the communication unit,
- wherein after the first control unit outputs a control signal to one of the safety maintenance devices, even when the second control unit outputs a control signal to the corresponding safety maintenance device, the control signal is set to be invalid.

- a second control unit that outputs a control signal for controlling the safety maintenance device to the safety maintenance device through the communication unit,
- wherein after the first control unit outputs a control signal to one of the safety maintenance devices, when predetermined time elapses or the information detected by the safety detection device is changed, the control signal output to the corresponding safety maintenance device by the second control unit is set to be valid.
9 more elements
A control method of a safety maintenance device provided on a ship, the control method comprising:
- a step of acquiring, by an on-ship system provided on the ship, information detected by a safety detection device for preventing disasters occurring in the ship provided on the ship and information indicating an operation state of the safety maintenance device;
- a step of transmitting, by the on-ship system, the information acquired in the step of acquiring to a land system provided on land;
- a step of acquiring, by the land system, the information transmitted in the step of transmitting;
- and
- a step of transmitting, by the land system, a control signal for controlling an actuator included in the safety maintenance device to the safety maintenance device,
- wherein after a control unit, which is included in the on-ship system and controls the safety maintenance devices, outputs a control signal to one of the safety maintenance devices, even when the land system outputs a control signal to the corresponding safety maintenance device, the control signal is set to be invalid.
