Abstract
A marine vessel maneuvering system includes an operator, propulsion device controllers each configured or programmed to control driving of a respective propulsion device based on an operation signal from the operator, a first communication bus to transmit the operation signal to some of the propulsion device controllers, a second communication bus to transmit the operation signal to a remainder of the propulsion device controllers excluding the some of the propulsion device controllers, and a gateway device to connect the first communication bus to the second communication bus such that the first communication bus and the second communication bus communicate with each other.
Claims20
A marine vessel maneuvering system comprising:
- an operator to receive an operation to drive a plurality of propulsion devices attached to a hull;
- a plurality of propulsion device controllers in the hull and outside the plurality of propulsion devices, one for each of the plurality of propulsion devices, configured or programmed to control driving of the plurality of propulsion devices based on an operation signal from the operator;
- a first communication bus to transmit the operation signal to some, but not all, of the plurality of propulsion device controllers, the first communication bus being connected to the some of the plurality of propulsion devices;
- a second communication bus to transmit the operation signal to remaining propulsion device controllers excluding the some of the plurality of propulsion device controllers, the second communication bus being connected to the remaining plurality of propulsion devices;
- and
- a gateway device to connect the first communication bus to the second communication bus such that the first communication bus and the second communication bus communicate with each other;
- wherein
- an upper limit number is set in the plurality of propulsion device controllers for the plurality of propulsion devices on which the plurality of propulsion device controllers perform a coordinated control to coordinate the driving of the plurality of propulsion devices based on driving information regarding driving of the plurality of propulsion devices;
- and
- the gateway device is configured or programmed to reduce a number of pieces of the driving information transmitted from one of the first communication bus and the second communication bus to the other.
