Research Of Synthetical Information System For Vessel Monitoring In Zhoushan Water Areas

The rapid development of information technology promotes the sustained improvement of ECDIS (Electronic Chart Display and Information System, ECDIS), and, it also supplies hardware and software platform for the further development of electronic chart technology. Zhoushan district situated on the center of Chinese coasting, also the south of the Changjiang river inlet, has a developed seafaring, so it definitely needs high level for vessel monitoring and management. ECDIS is convenient to navigation workers to monitor and control the vessel owing to owning functions of chart displaying and vessel monitoring. While current electronic chart usually owns basic functions, so the electronic chart that has more functions and can contain more information becomes navigation workers' requirement.In this thesis, basic platform of ECDIS is built, based on the electronic chart software of EC-IVMS and the Zhoushan district as the research area. Moreover, some relative functions are extended in the ECDIS: additional of the function of building the chat database, which makes it import the S-57 standard chart; receiving and sharing SAIS(Small Automatic Identification System) information, thus the network of electronic chart is realized; making the weather information become data, then saving them in the database, and finally, bringing them into the visual space by ECDIS, like this way of which makes a pile of bald data become the direct viewing picture. The application research of the visualization of weather data information in electronic chart is less at present. Some attempts are done in this thesis. The main research works of this thesis are as follows:1) Chart database is built and several standard chart files are imported into ECDIS. Hence database file is built.2) Showing SAIS in ECDIS. By remotely connecting SAIS server end and synchronously receiving the SAIS, the vessel information is synchronously displayed in ECDIS and database is built to store the receiving vessel information. The SAIS information is sought in the database to realize the information redisplaying of the vessel position according the real condition and therefore the vessels position is confirmed.3) The visualization of wind, current, wave in ECDIS. The isoline theory is narrated with which the visualization of water level is realized. Besides, under the corresponding model, the data of wind, current and wave are read, so the visualization of these is realized in ECDIS.
