ARM and FPGA based ship power positioning control system

Abstract

The invention discloses an ARM and FPGA (Field Programmable Gate Array) based ship power positioning control system which comprises a main control computer, a collecting module, a console controller and a propeller, wherein the main control computer, the collecting module and the console controller are connected with each other through a first network; the console controller is also connected with a second network; the console controller and the propeller are connected with each other through the second network; the collecting module is used for transmitting sensor data and propeller data to the main control computer; the main control computer is used for calculating a ship position according to the sensor data and calculating a propellant volume according to the propeller data; the console controller is used for reading practical operation information on a console and the propellant volume of the propeller, reading the state of the propeller and feeding back to the main control computer. The system disclosed by the invention is rich in hardware interfaces and industrial bus protocols, can meet the requirements of node redundancy and network redundancy, is high in communication efficiency and is high in system response speed.

Description

technical field [0001] The present invention relates to embedded control and ship dynamic positioning system, more specifically, relates to a kind of ship dynamic positioning control system based on ARM and FPGA. Background technique [0002] With the exploration and utilization of marine resources, as well as the development of navigation science and technology and marine engineering, human beings have gradually moved from shallow seas to deep seas. Related technologies are developing rapidly. [0003] The purpose of the ship dynamic positioning system is to maintain the position and course of the ship. The system does not rely on the mooring system. According to the direction of the real-time wind, wave and current, it uses its own propeller to generate propulsion and moment offset to resist the interference of the external environment, and automatically Adjust the heading of the ship to the optimal desired position. Compared with the mooring system, the dynamic position...
