Control device and control method for unmanned boat outboard motor

Abstract

The invention discloses a control device and control method of an outboard engine of an unmanned ship. The control device comprises an outboard engine fixed at the tail of the unmanned ship; a control mechanism of the outboard engine is connected with electric push rods through soft control shafts; an ignition / flameout control circuit of the outboard engine is connected with a voltage output module through an ignition / flameout control cable of the outboard engine; a sliding potentiometer is arranged in parallel under each electric push rod; the tail end of the push rod of each electric push rod is connected to the tail end of a sliding rod of the corresponding sliding potentiometer in a fastening manner; the power line of each electric push rod, the power output line of each sliding potentiometer, and the power output line of the voltage output module are separately connected with a signal control circuit; the signal input end of the voltage output module is connected with a shipborne embedded controller. The control device disclosed by the invention overcomes the difficulties and defects of applying a hydraulic control device during driving the unmanned ship, and combines the advantages of a mechanical control device; a manner that the electric push rods combine the mechanical soft shafts is adopted, so that the control precision and the reliability are guaranteed, and the automatic control of a throttle, rudder angles and shifts is realized.

Description

Technical field [0001] The invention belongs to the technical field of ship power control, and specifically refers to a control device and a control method of an unmanned boat outboard motor. Background technique [0002] Unmanned Surface Vessel (USV) is an unmanned surface vessel. Small USV is also called unmanned boat. One of the key technologies of the unmanned boat power platform is to achieve precise and reliable control of the speed and heading control mechanism under the limited power source and cabin space constraints of the small boat. [0003] At present, the automatic control devices for the speed and course of surface vessels are mainly realized by hydraulic systems. The specific method is to establish a stable pressure for the hydraulic system through the continuous work of the hydraulic pump, and the solenoid valve receives the signal from the control system to generate actions and change the on-off state and flow direction of the hydraulic oil in the hydraulic circu...
