Problems solved by technology
At present, the manipulators on the market mainly use the rotation of the potentiometer as the angle sensor of different gears. The disadvantages of this angle sensor are: the proportional transmission mechanical structure is adopted, which is large in size and cannot be miniaturized; it requires high assembly accuracy; Physical wear reduces the rotation accuracy; the installation form is single, the waterproof design is difficult to handle, the waterproof performance is not good, the waterproof level is generally IP22, and the cost of the waterproof structure is high

The invention discloses a method for controlling an accelerator gear of a remote control manipulator of a ship main engine. Current rotation angular velocity data of a control handle and a control base are respectively transmitted to a microcontroller in real time through two MEMS motion sensors, current rotation angles of the control handle and the control base are respectively calculated by themicrocontroller, a space vector after the control handle rotates is calculated, and a current actual rotation angle of the control handle is calculated, the current actual rotation angle data of the control handle are transmitted to the microcontroller through a CAN communication circuit, finally the microcontroller calculates and determines the actual accelerator gear corresponding to the currentactual rotation angle of the control handle, and remote control and switching of the accelerator gear of the ship diesel engine are achieved. The method can effectively eliminate the rotation of thecontrol handle caused by the shaking of the ship body under the action of wind waves and other external forces, and ensures that the rotation of the control handle every time is equal to the manual operation, thereby ensuring the remote control precision of the accelerator gear of the ship diesel engine.
Description
technical field [0001] The invention belongs to the field of ship control, in particular to a method for controlling the throttle position of a remote control manipulator of a ship main engine. Background technique [0002] The main engine remote control manipulator equipped on the ship is a man-machine operation device that uses different gears to control the throttle of the ship's diesel engine. At present, the manipulators on the market mainly use the rotation of the potentiometer as the angle sensor of different gears. The disadvantages of this angle sensor are: the proportional transmission mechanical structure is adopted, which is large in size and cannot be miniaturized; it requires high assembly accuracy; Physical wear reduces the rotation accuracy; the installation form is single, the waterproof design is difficult to handle, and the waterproof performance is not good. The waterproof level is generally IP22, and the cost of the waterproof structure is high. [0003...
