Electric steering engine servo device for ship

Abstract

The invention discloses an electric steering engine servo device for a ship. The device comprises the components of an upper computer which outputs a control rudder angle value of a motor driver of aship; an STM32 controller which receives the rudder angle value transmitted by the upper computer; the STM32 controller transmits the rudder angle value to the stepping motor driver and stores the rudder angle value; the output end of the stepping motor driver is connected with the stepping motor; an output shaft of the stepping motor is connected with the gear box, and rotation of the gear box iscontrolled according to the received rudder angle value. The device further comprises an angular displacement sensor used for detecting actual rudder angle information of the ship. The angular displacement sensor transmits a detected actual rudder angle value to the STM32 controller; and the STM32 controller compares the rudder angle value given by the upper computer with the actual rudder angleto obtain a rudder angle difference value, performs rudder angle compensation control on the stepping motor according to the rudder angle difference value, and stops the rudder angle compensation control until the actual rudder angle is equal to the given rudder angle value.

Description

technical field [0001] The invention relates to a marine electric steering gear servo device in the technical field of ship servo, in particular to a servo device that provides reliable propulsion and rudder steering functions for ships. Background technique [0002] With the rapid development of automation technology, unmanned ships will become the key research direction in the future, and in the research of unmanned ships, stable and accurate control becomes the place that must be paid attention to, so it is required to control the steering gear more accurately ,fine. In terms of precise control, marine electric steering gear is undoubtedly the most ideal choice, and the use of marine electric steering gear has become inevitable. [0003] Traditional ship steering gear servo systems generally use hydraulic drive, which has many shortcomings in terms of efficiency, maintainability, controllability and integration, such as complex system debugging and maintenance, hydraulic...
