Research on Ship AIS Data Analysis Based on Stream Computing and Virtual Fence

With the development of smart maritime construction, ship virtual fences have been applied in areas such as ship entry and exit, bridge area navigation safety, and checkpoint management. By combining the ship virtual fence and stream computing technology, a real-time ship automatic identification system (AIS) data analysis platform is developed. It tracks the position and navigation status of ships in the virtual fence area. This platform has been validated in the Jiangsu section of the Yangtze River basin, and it effectively improves the intelligent level of maritime supervision.
