Collision Avoidance Research And Development Of Computer-aided Instruction And Simulation System Of The Collision Situation

In order to avoid ship collision accidents, ensure the safety of the navigation and protect the marine environment, IMO has made and issured a series of rules and regulation. Such as the "INTERNATIONAL REGULATIONS FOR PREVENTING COLLISIONS AT SEA, 1972" and STCW78/95. At the same time, for the implementation of these regulations and according to the universal leading law of education, higher request for navigation education has been put forward, certain reforms should be undertake on the present navigation education. Among the navigation professional courses, "Prevention of Collisions and Watchkeeping of Ship" is one of the most important courses. The teaching quality of this course will determine the students' comprehension and application of the avoiding collisions rules. It also influences whether the crew can adopt the correct action in ship handling and the avoidance of collision. It comes to become the key point receiving all attention from the education circle of navigation for how to improve the teaching means and strengthen students' comprehension and applied ability of regulation.The system of the computer-assisted instruction and simulation for preventing collision is a multimedia courseware of research and development against above-mentioned situations and it aims at using the advanced teaching means to improve the teaching results. This software is mainly composed of two parts: first is the teaching system of shipping avoiding collision, second is the simulation of the ship collision. The teaching system for avoiding ship collision is mainly involved with the content of the course "Prevention of Collision and Watchkeeping of Ship" with all the advantages of the multimedia means. This system employs a large number of sounds, pictures and cartoons, making the whole courseware vivid and lively, and plays an important role in improving the teaching quality. The simulation system of the situation of ship collision mainly shows several kinds of typical situations. It is divided into three parts. First one defines various kinds of situations, and the relative position between the vessels in these situations. Second one describes the rule for preventing collision in various kinds of situations, and utilizes the cartoon toimitate the avoiding action; Third one uses the typical case to imitate and analyze the questions that may appear or occur often in the action for preventing collision.On the basis of this software, the characters of the paper made up of six parts mainly: The first part is an outline part of the thesis, introducing the background knowledge and the actual meaning of the subject. The second part introduces the developing instrument, the system function and the whole framework of the software. The function and framework of the software is introduced from two aspects respectively of, namely ship collision avoiding system and the simulation system of the ship collision situation; The third part provides the flow charts and every interfaces characteristic of the software; The fourth part is the key part of this text, explains the thought and method of sound, picture, cartoon material and the characters script of the instruction system, especially the design principle and course of every interface of the software system; The fifth part presents several kinds of situations and characteristics that shipping will be probably met and introduces the way of design and method about the software of ship collision situation simulation; The sixth part is a conclusion of the thesis. There is operation manual this software at the end of the thesis, belonging to the appendix part of the thesis.
