Research The Decision System Of The Ships Evade Bump Based On The AIS Information Environment

Automatic Identification System(AIS) is one kind may transmit the great information content, surmount an obstacle, the anti- weather influence, has between the ship -shore, the ship - ship the information networking ability and the short distance target indication global ship carries the automatic diagnosis system. In the International Maritime Organization, the International Association of Lighthouse Authorities, the International Telecommunication Union, the International Electrician technical Committee and so on under the related international organization's joint effort, the international maritime affair conference started from 1992 to deliberate the AIS question, has issued the AIS performance standard, the technical characteristic, the test standard and the operation manual and so on.The present paper the data which provides AIS evades as the ships bumps the decision system the information environment to originate, evades using the computer technology research based on the AIS information environment ships bumps the policy-making technology. The article first acts according to the domestic and foreign materials, the publication paper and the International Maritime Organization's related document, has carried on the induction, the reorganization to the AIS system technology, analyzed the AIS data to be opposite the superiority and the AIS data precision which in the radar, the ARPA data said; The domestic and foreign ships evade at present in the analysis bump the decision system research condition in the foundation, discussed has puzzled the ships to evade for a long time bumps the decision-making technological development the key question, proposed applied the AIS technology to the ships evades bumps policy-making the tentative plan. Discussed in a ships collision danger determination has evaded based on the AIS information environment ships bumps the fuzzy judgment matrix, the time collision danger and the spatial collision danger and its the synthesis collision danger mathematical model, and as concrete realized the algorithm take this mathematical model, in evaded bumps the knowledge library under the support, has developed the simulation system with the C language.The present paper research direction only aims at the broad sea area the ships to evade bumps the decision-making, but evades based on the AIS information environment ships collision dangerous number of degree study model establishment as well as the ships bumps policy-making proposing, along with the AIS technology characteristic further enhancement, evades to the gut ships bumps, under the heavy weather environment the ships evades bumps has the epoch-making practical significance, at the same time also even future the navigation center ships intelligence automatically will evade to at present bumps the system the comprehensive research and development to bring the great practical value.
