For Waterway Transportation Information Platform Data Processing Technology And Applied Research

The complete waterway transportation information platform is the basis of the construction of the efficient, safe and economical waterway transportation system. And Accurate and reliable data is the important safeguards of the waterway transportation information platform traffic normal operation. This thesis takes the waterway transportation information platform' supporting data as the research object, analysis and research the technology and the method suitable for the waterway transportation data and message processing. In order to improve the data's completeness, accuracy and reliability, and provides the oretical basis and the technical method, then make the accuracy of the waterway transportation information platform'decision-making.Based on the analysis of the flow of information about the waterway transportation information platform data message, proposed the structure of the data message processing system. In view of the data collection and the data information source's characteristic, has carried on the classification to the waterway transportation data message.Unifies the existing data message' characteristic, based on the analysis of the data cleaning technology, the data integration and in the data conversion technology, successfully applies the data cleaning technology to the waterway information, and puts down the pretreatment of the noise data, the unusual data, the flaw data, has promoted the data quality and has guaranteed the data message'accuracy and completeness. Take the data cleaning technology as the foundation, established the data message cleaning pretreatment module of waterway transportation information platform.Finally this thesis has studied the application about the dynamic data message'processing of the data fusion technology in the waterway transportation, has established the kalman filtering structure and unites kahnan filtering structure. Has realized to the error correction of the ship heading and speed information on the DR/GPS combination system, the simulation analysis indicated that, the data fusion technology can enhance the precision of the ships localization information on the ships dynamic monitoring the ships localization information precision, has guaranteed the accuracy and the reliability about the data message.
