Research On The VTS Information Management System

This thesis brought forward the implement scheme of the VTS information management system and caught it into execution basing on the requirement of VTS to the information management subsystem and the study on the implication of the database technology in the system. Managing the vessel information, information management subsystem can assist operator to supervise the vessel traffic and offer the reliable information to the department of vessel traffic programming and decision-making. But conventional information management system can't meet with the development of the VTS system in many aspects, especially on the function of mining the vessel traffic rule from a great lot of vessel data. So the thesis conducted the research on the disadvantage mentioned above.In the research of the distributing function in the statistic character of the vessel traffic volume, the thesis analyzed maximum entropy fitting algorithm and put forward a new algorithm named polynomial-fitting-algorithm basing on the idea of lease-square-algorithm. The thesis also proved the feasibility of the new algorithmthrough comparing with %2 check. At the same time, this thesis introduced a statisticmethod ?round distribute method on the research of the rule of the vessel traffic to calculate the fastigium of the traffic volume.This thesis discussed the database technology, which is used to realize information management system, compared a few data models and established the system scheme and realized the system combined with the technology of data mining.This subject came from the item of Ministry of Communications named "The Development of VTS Operating and Training Simulator". The information management system is the important component of the simulator. This item has been appraised.
