Information Module Design Of Unmanned Ship Based On Information Fusion

With the rapid development of maritime transport, the ship collision accidentrate is much higher than before by the increasing number of ships. So the rescueproblem is becoming more and more serious. Unmanned ship which can performrescue missions in the extreme environment of sea area has a great applicationprospect.In order to further improve the function of unmanned ship, we must makeeffective fusion of shipboard sensors to provide a more accurate and reliable datasources for control decision. Base on the science and technology project of ChinaMSA, this dissertation study on the application of information fusion technology tounmanned ship platform.Firstly, the dissertation designs the information acquisition and fusion subsystemof the unmanned ship. And it analyses the function of Information acquisition andfusion. So it can determine the function design schemes.Secondly, based on information acquisition method, it makes the design theinformation acquisition circuit plate. The dissertation can finally take industrialcontrol computer as the core, with STM32-F103C8T6as the main chip of informationacquisition and CAN-bus, one to one information acquisition mode.Thirdly, on the basis of information fusion schemes, the dissertation analysesradar tracking algorithm. And it moves on to the simulation on filtering algorithm inship tracking. The final choice is Filtering algorithm with variablecoefficients，because of its better filtering effect. Further more in this dissertation,according to the features of radar tracking theory and navigation. The dissertationgives the realized scheme of radar tracking algorithm and simulate its tracking effect.Finally, based on information fusion theory, the dissertation analyses informationfusion pretreatment and data fusion methods of AIS and radar, and choose the bestalgorithm which according to ship navigation features. Determine the trackcorrelation algorithm which based on the target position and data fusion algorithm.Calculate the weights of AIS and radar in the weighted data fusion algorithm, and simulate its fusion effect.In this dissertation, it is based on the information acquisition and fusionsubsystem design-oriented, and has researched on AIS and radar information fusion,designed the AIS and information algorithm which is on the basis of informationacquisition and integration subsystem. The most important part is the simulation. Itcan improve data accuracy and reduce data fluctuation.
