Design of Unmanned Ship System with Two Engines and Two Propellers

Abstract

Unmanned ship is a kind of surface robot with integrated technology, which is composed of multiple disciplines, including intelligent remote control, wireless communication, autonomous navigation and obstacle avoidance algorithm.When the unmanned ship is sailing in the water, it is difficult to control its dynamic performance due to the influence of sea conditions. Therefore, the research on the unmanned ship technology has extremely important practical value. In order to improve its maneuverability and control accuracy, an unmanned ship based on two engines and two propellers is proposed. This paper designs an unmanned ship bottom system with two engines and two propellers. The system is mainly composed of two main engines, including two generators and two rudders and propellers. Two of them adopt Controller Area Network communication protocol and are controlled by two Controller Area Network communication interfaces respectively; The two generators adopt RS485 serial port communication protocol and are controlled by two RS485 serial ports respectively; The two-rudder propeller equipment adopt RS485 serial port communication protocol and are controlled by the other two RS485 serial ports respectively.Through the experiment, it is found that the unmanned ship equipped with two engines and two propellers can better control the navigation accuracy of the ship and have high maneuverability.
