2 Applied Mechanics and Materials Vol International navigation Simulator Association taking into account the STCW78/95 Simulator-related requirements of the Convention and to ensure and improve the quality of simulator training, classification on the Simulator, simulators are divided into four categories, namely: (1) Visual Simulator (Full Mission): the capacity to simulate all the environment, can be ship maneuvering in narrow waterways and water training. Equipped with actual ship-like driving and all nautical instruments, equipment and high-quality visual, boat and marine environment, sound systems, different regions and various types of ships and marked, movements, and so on. (2) multi-purpose simulators (Multi Task): ability to simulate navigation environment, can be used in restricted waters ship handling training. Equipped with a radar simulation equipment and with limited vision (seeing lights). (3) limited functionality Simulator (Limited Task): simulation of navigation and collision-free environment with limited capacity. Equipped with a radar simulation equipment (including coaches and radar vessel, ignoring the King). (4) simple functionality Simulator (SingleTask): Desktop System Simulator. Running on the PC. Hardware systems In General, General ship handling Simulator has the following equipment: equipping the clock visual displays to display day and night as well as a variety of visibility Visual; more complete driving equipment operation devices, to simulate and display more intuitive navigation and manipulation of ships at sea or in port, specifically: Driving Simulator. Simulation driving Taiwan by fuck rudder control Taiwan, and radar, and rudder corner indicator, and speed table, and speed table, and measuring deep instrument, and log and wind speed wind instrument, composition, fuck rudder control Taiwan is a multifunctional control Taiwan, in addition to has automatically, and with dynamic, and emergency 3 kind of fuck rudder way outside, also equipped with double car clock, and cycling clock, and displayed navigation Shi various data of CRT and fog flute, features key. Hardware systems are often diwu, Liu-generation container ships and other types of ship design, IBS system designed to simulate driving; training of personnel in the driving simulator you can operate and control. Coach monitoring stations as the system control center, equipped with console including coaches, the ship's radar surveillance system, VHF communication system, monitoring system as well as the track record of driving simulator apparatus and devices such as printers. And through graphics, easy operation, such as dialog boxes, menus, provides a friendly interface for coaches through this interface, coaches can work easily. Software systems Software systems are the key to this system, to meet training requirements, systems conforming to the actual characteristics of ship models, radar, Visual, electronic charts and other nautical stories, specifically: L) ship models and navigation controls Mathematics through differential equations modeling techniques to develop different types of ship models. Hydrodynamic calculation for simulation of ship navigation by ships. 2) to electronic chart as the background operation waters 3) generation of radar/arpa images /ARPA image generation system of radar, ARpA and radar images of the training area information,. Radar images including: shoreline echo echo of ECHO, fixed and moving targets. In addition, radar images generated, plus the radar false echoes, radar co-channel interference effects on radar, unusual atmospheric conditions, as well as on radar performance parameter simulation, simulation of radar's minimum detection range. 4) sound system In order to create and ship navigation environment and atmosphere of closer. Systems generally use multimedia technology to generate and control driving-related noise. Simulates the car, back under a variety of different speeds of sound, and his boat the boat fog horn.

System including the examination and assessment of project settings, real-time playback, ship handling training process features such as recording, examination scores. And manipulation of warning signals, left, twist anchors and ship collision sound. Design of ship maneuvering Simulator System At present, simulator training process, without taking into account the examination and assessment of individual capacity factors, in the training of practical examinations and assessment, for various reasons, with participants of this ship in a training project will assess performance with large differences, sometimes even on the same vessel differences in student achievement are large. Visible, evaluators of random scores cannot be truly fair and equitable, thus they reflect the nautical technology in simulation system for the examination and assessment system software there are some unsatisfactory place, lagging behind in development and application features. System is designed to take into account the multiple factors and human factors in maritime navigation effects, by establishing standards of discipline database and combines intelligent expert system to provide real-time collision avoidance programmes, compared to the procedures for training personnel, followed by fuzzy comprehensive evaluation and expert system of joint practical score to achieve effectiveness of training. Composition of the system Examination and assessment system of basic thought is uses existing Simulation Manager on students training for assessment, systems engineering component has: on students standard painted, and fuck ship, and collision avoidance and confrontation training Shi of history track of data acquisition and the calculation subsystem, and to standard answers as assessment reference standard of standard database subsystem, and using expert smart system and fuzzy integrated evaluation combined and consider multiple errors, factors Hou on results for assessment of results assessment subsystem. Subsystem data acquisition and calculation: according to the different assessment objects, such as: single, multi-object marking assessment objects; navigational training assessment; combat training assessment objects, such as the use of different sampling methods. Navigation training assessment, due to ship more, the sight this ship, change, this type of assessment is more complicated. If the data from the entire shipping process, the amount of data and it is difficult to deal with. If you capture technology using computer, get on the radar screen at a certain moment photos, photos for analysis and evaluation method is more simple and practical. Standard database subsystem: according to set criteria for the examination and evaluation database. This is to compare with trainers in practical assessment and establish a database reference.
