Title:
HOLDING UNIT FOR CONSTANT SLOW SPEED AND FIXED POINT OF SHIP
Document Type and Number:
Japanese Patent JPH01226492
Kind Code:
A
Abstract:
PURPOSE:To enable constant slow speed navigation and holding at a fixed position of the hull to be carried out accurately by detecting the position or speed of the hull and controlling an acceleration/deceleration means for increasing/decreasing the number of revolution of a propeller on the basis of this detected signal. CONSTITUTION:In order to detect the incident angle of a fishing line 13 to hold the hull at a fixed point, a signal from an incident angle detecting means 7 for the fishing line 13 is inputted to CPU 2 via an input circuit 5. Further, an incident angle set by an incident angle setting means 8 is also inputted thereto via the input circuit 5. The signal from the CPU 2 passes through an output circuit 6 to be outputted to an number of revolution increasing/decreasing means 9 to control it, so that the hull is held at the fixed position.
