Aiming at the fact that target ships of ship handling simulator have not the ability of avoiding other ships according to the COLREG 1972, the paper puts forward to add Personifying Intelligent Decision-making for Vessel Collision Avoidance, for short PIDVCA, and vessel automatic control algorithm into solver procedure of target ship, designed and realized target ships to sail according to the COLREG 1972, which make ship handling simulator more realistic simulate the actual navigation environment at sea. Finally, the paper gives the simulation pictures of 2 and 4 target ships intelligent collision.
Due to the target ship in the traditional ship handling simulator have not the ability to give way to other ships automatically to avoid collision, this paper put forward a new idea that bringing the hydraulic servo platform, six degrees of freedom ship mathematical model, the actual traffic flow, researching achievement of automatic anti-collision in research of the new pattern ship handling simulator, and successfully develop the Intelligent Ship Handling Simulator(ISHS for short). The paper focuse on the research on the network communication model of ISHS. We took the entire simulator system as three relatively independent networks, proposed a framework of communication network that combined IOCP model based on TCP with blocking model based on UDP, and gave the communication process and protocols of system. Test results indicate that this is an effective way to improve the ownship capacity of ship handling simulator and meet the need of multi-ownship configuration of desktop system of ship handling simulator.
With appearance of variety kinds of three-dimension buoy application system, the design and production of three-dimension virtual model of buoy is increasingly becoming an important and tedious work. Artificial modeling way adopted in the past is inefficient, and the light quality is difficult to achieve. The paper puts forward automatically generating method for three-dimension virtual model of buoy based on S-57 chart data (AGM for short), and describes extraction and analysis of buoy data from S-57 chart data, automatically generation of three-dimension buoy model and the flashing animation of buoy light quality in detail, and finally gives the experimental data and results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
