Abstract

An operation device in a ship propulsion system including a ship propulsion machine, ship-mounted equipment, and a power supply, the operation device including a single push button switch and an operation processor performing processing. The operation processor detects a pressing mode of the push button switch when the push button switch is pressed while the ship-mounted equipment and the power supply are disconnected and the power source is stopped, performs processing of connecting the ship-mounted equipment and the power supply and starting the power source when the detected pressing mode is a first mode, and performs processing of connecting the ship-mounted equipment and the power supply while maintaining the power source in a stopped state when the detected pressing mode is a second mode.

First claim

What is claimed is:

1. An operation device in a ship propulsion system including a ship propulsion machine provided in a ship, ship-mounted equipment that is electric equipment provided in the ship, and a power supply provided in the ship propulsion machine or the ship, the operation device configured to perform an operation of connecting or disconnecting the ship-mounted equipment and the power supply and an operation of starting or stopping a power source of the ship propulsion machine, the operation device comprising:
a single push button switch; and
an operation processor configured to perform processing in response to pressing of the push button switch, wherein
the operation processor is configured:
to detect a pressing mode of the push button switch when the push button switch is pressed while the ship-mounted equipment and the power supply are disconnected and the power source is stopped, to perform processing of connecting the ship-mounted equipment and the power supply and starting the power source in a case where the detected pressing mode is a first mode, and to perform processing of connecting the ship-mounted equipment and the power supply while maintaining the power source in a stopped state in a case where the detected pressing mode is a second mode, and
to perform processing of stopping the power source and disconnecting the ship-mounted equipment and the power supply when the push button switch is pressed while the ship-mounted equipment and the power supply are connected and the power source is in operation.

2. The operation device according to claim 1 , wherein
the operation processor is configured to detect a pressing mode of the push button switch when the push button switch is pressed while the ship-mounted equipment and the power supply are connected and the power source is stopped, to perform processing of starting the power source while maintaining a state where the ship-mounted equipment and the power supply are connected in a case where the detected pressing mode is the first mode, and perform processing of disconnecting the ship-mounted equipment and the power supply in a case where the detected pressing mode is the second mode.

3. The operation device according to claim 1 , wherein
the operation processor is configured to detect a pressing mode of the push button switch when the push button switch is pressed while the ship-mounted equipment and the power supply are connected and the power source is in operation, to perform processing of stopping the power source while maintaining a state where the ship-mounted equipment and the power supply are connected in a case where the detected pressing mode is the first mode, and to perform processing of stopping the power source and disconnecting the ship-mounted equipment and the power supply in a case where the detected pressing mode is the second mode.

4. The operation device according to claim 1 , wherein
the ship propulsion machine includes a propeller and a power transmission switching device configured to switch a position of a gear that transmits power of the power source to the propeller between a connection position at which the power of the power source is transmitted to the propeller and a disconnection position at which the power of the power source is not transmitted to the propeller, and
when performing the processing of stopping the power source, the operation processor is configured not to stop the power source when the position of the gear is the connection position.

5. The operation device according to claim 1 , wherein
the operation processor is configured to disconnect the ship-mounted equipment and the power supply when a state where the power source is stopped and the ship-mounted equipment and the power supply are connected continues for a predetermined time.

6. The operation device according to claim 1 , wherein
the operation processor is configured to detect a duration of a state where the push button switch is pressed as the pressing mode of the push button switch, the first mode is a mode in which the duration of the state in which the push button switch is pressed is less than a first reference time, and the second mode is a mode in which the duration of the state in which the push button switch is pressed is equal to or longer than a second reference time longer than the first reference time.

7. The operation device according to claim 6 , wherein
the second reference time is equal to a preset duration of output of an alarm sound in operation confirmation processing of an alarm device provided in the ship.

8. The operation device according to claim 1 , wherein
the operation processer is configured to start power sources of a plurality of the ship propulsion machines provided in the ship at the same time when performing the processing of starting the power source.
