| The Yangtze River is the longest river in China and the third longest river in the world. Its main stream flows through seven provinces and two cities, with the watershed area more than1.8million square kilometers. Furthermore, it is the only transportation corridor which runs across the eastern, central and western of our country, known as "Golden waterway". Many attentions have been paid to the shipping information construction of the Yangtze River. As a great role in the information systems of the Yangtze River route, Automatic Identification System (AIS) belongs to the "Eleven-Five" key construction projects of the Ministry of transport, and was officially put into use in2011.To make full use of the resources of Yangtze’s AIS, The author is entrusted to carry out the research named "the application system of Yangtze’s AIS" by the traffic planning research institute of the Ministry. This project aims at providing the vessel with information services, furnishing regulatory information and means for the shipping safety supervision department, and providing the shipping management department and the shipping enterprises with excellent management platforms, which is featured by informatization and modernization.Based on the former achievements related to AIS application of the Yangtze River mainstream, the integrated shipping logistics information platform has been put forward coorespondingly. With this platform, several key techniques sequentially from the perspective of the shipping logistics, the ship-connect network, and the maintaince and safety security of the green fairways have been comprehensively studied. Within this dissertation, the following achievements have been reached.Firstly, the integrated shipping logistics information platform has been constructed based on the AIS information of the trunk line of Yangtze River. After the overview of AIS, the AIS information decoding method based on VB language has been proposed. Organization structure of the platform is designed, and the information that each department should fetch from the platform are defined exhaustively. When comes to the heterogeneous characteristics of the shipping logistics information database, the study has been orderly carried out from the integrated model, the process and the architecture of the heterogeneous database. Then, the structure of the integrated shipping logistics information platform has been implemented. Within this platform, the key techniques that the shipping logistics, the ship-connect network, and the maintaince and safety security of the green fairways would confront with are addressed. The factors affect the stability of the platform are pointed out. For the first time, the technique based on adaptive technology programmes was devised to address AIS communication block problem. With our approach, the platform stability can be doubtless guaranteed.Secondly, based on our proposed platform, the key technologies of shipping and logistics have been studied. After analyzing the supply and demand information of shippers, freight forwarders, logistics companies and shippers, the information flow mechanism between logistics, shipping companies and the platform are clarified. The browse and inquery techniques related to the supply and demand information on ship and goods are stated. Using electronic charts as display platforms, shipping and logistics information extracted and updated in real time. Then, the critical monitoring technology of shipping and logistics process are resolved successfully.Thirdly, based on our proposed platform, the key technologies of ship-connect network and maritime safety have been studied. The networking scheme of the ship-connect network is proposed. The early warning concept field for the hazardous cargo ship was first proposed, and the real-time monitoring techniques are achieved. The ship security alert publishing technology which displayed with Chinese character is developed. With this technique, the Yangtze navigation security situation would be improved substantially. The marine security emergency response measures based on mobile VTS technology are proposed and implemented, with this technique, the safety of ships ensurance capability of the ship-connect network would be enhanced effectively.Finally, based on our proposed platform, the key technologies of the maintaince and safety security of the green fairways have been studied. The virtual buoy navigation system which based on AIS is put forward subtly. The real-time monitoring technology for waterway depth is developed. With this approach, we can identify the navigational safety for ships and acquire the changed water depth information with ease. Based on AIS information, the automatical statistics software developed by artificial neural network technology can be used to calculate the vessel traffic flow. To analysis the traffic flow distribution, one typical sector of the Yangtze River are chosen. High automatical Channel capacity prediction model is established and conducted applied research to improve waterway maintenance capabilities. The waterway navigation safety assessment techniques based on AIS information which leading the fairway green security technologies remarkably are proposed.This dissertation seeks to make full use of the existing resources, economic, and efficient constructing the integrated shipping logistics information platform. Within this platform, the three key facets which are the shipping logistics, the ship-conncet network, and the maintenance and security of the green fairway are studied elaborately. Research results on this innovation platform will facilitate the construction of the Yangtze Golden waterway, and promote industrial upgrading of the Yangtze River evidently. |
