Abstract: In practice, persons on duty always analyze whether a watercraft has crossed the boundary by visual observation and experiential judgment, while in severe weather conditions or in broad stretches of the river where navigational aids are not properly distributed, the above-mentioned methods have potential safety hazards. It is necessary to use the navigation-aid alarm system to assistant with decision-making. By integrating three subsystems of positioning, identification and alarm, the Beidou Navigation Satellite System and GIS systems are integrated, network map resources are rationally used, the alarm area databased is established, and the plumb line method and CalcIntersectPoint function are used to recognize and judge the status of the ship. This paper introduces the features and design ideas of the boundary alarm system for ship navigation on the boundary river, clarifies the process of manufacturing and realizing the system, and verifies and analyzes its performance. The results show that the realization of the alarm system can provide some theoretical, technical and data support for the further development of the boundary alarm system for ship navigation on the boundary river.
