Abstract

To reduce caused the ship misuse, the various types of losses, reduce staff working pressure and ships to economic efficiency, integrated bridge system gradually developed. The system includes a large number of research content, path planning technology as a key technology, mainly refers to the routes automatically generate and optimize the process. Previous voyage planning techniques require inspection by the staff of nautical books and recommended route information manually through the analysis of the trend, such as the information is entered into the system, so that did not play smart integrated bridge system. This paper studies taking into account the limitations and constraints of the traditional track planning study methods to track planning and design of the ship informed of the sailing area information, the use of computer technology and modern control theory and technology. Dimensionality explosion in solving complex environment for pure mathematical programming methods, long computation time, this paper two intelligent algorithm - ant colony algorithm and genetic algorithm to expand the route planning design. A more in-depth study of the first article of the ant colony algorithm and genetic algorithm's basic theory, algorithm structure and algorithm characteristics; Second ship sailing space modeling no-fly zone, by modeling the fixed position of the navigation environment (isobath area or to navigation area) to carry out the necessary processing. And in accordance with the requirements of IHO S-57 (third edition), the location of the no-fly zone to expand the area expanded to form a ring, the ring inside the no-fly zone is not feasible, the external ring again in the area of ??freedom of navigation; modeling based on the space, according to the ship's sailing characteristics of the ant colony algorithm and genetic algorithm algorithm internal structure parameters necessary improvements, and two algorithms applied to the ship's route planning, integrated bridge system The basic track planning and design; the final trajectory planning the best route plan design requirements the yaw limit and safety distance from shore concept of Best Route Planning design to protect the safety of the ship traveling. Also considering the various factors affecting the weather on the route, downstream of Route Planning under the influence of the ship in a different direction and focus of the simulation, ship energy conservation, efficiency play a role. The basic route of the flight path planning technology design and best route design in the article by Matlab software simulation to achieve design efficiency and design accuracy is improved compared with the traditional method of hand-drawn track; than the access to existing route map means to enhance the flexibility of the design. Through various simulation results prove that the use of intelligent algorithm Planning Track fast, convenient and flexible, can be better used in different navigational environment.
