Problems solved by technology
[0003] However, the fog in the port is not only sudden, but also irregularly distributed in the port. For example, sometimes the visibility at the anchorage is 2 nautical miles, while the line of sight in the port area is less than 0.5 nautical miles. Timely discover that the ship is about to or has entered the fog zone, which will affect the safety of the ship's fog navigation
However, because the driver or the watchman is in this lookout state for a long time, it is easy to get tired, the attention, judgment, and decision-making ability are reduced, and there is a fluke mentality, which makes it difficult to deal with emergencies

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] figure 1 It is a schematic diagram of the structure of the enhanced system for fog navigation safety navigation of ships in the port of the present invention.
[0025] See figure 1According to the present invention, the system for enhancing safe navigation of ships in fog in a port includes a navigation mark information collection and transmission subsystem, a shore-based information processing subsystem, a Beidou ship-borne application subsystem, and an AIS ship-borne application subsystem. The navigation mark information acquisition and transmission subsystem of the present invention communicates with the shore-based information processing subsystem through the Beidou satellite link. The advantage is that the Beidou satellite communication has no distance limit and no blind spot for observation, and can provide accurate observation position an...

The invention discloses a safety navigation enhancement system for navigation in fog of ships in a harbor. The safety navigation enhancement system comprises a navigation-aids information acquisition and transmission subsystem, a shore-based information processing subsystem, a Beidou ship-borne application subsystem and an AIS (automatic identification system) ship-borne application subsystem, wherein the navigation-aids information acquisition and transmission subsystem communicates with the shore-based information processing subsystem through a Beidou satellite link, and the shore-based information processing subsystem communicates with the Beidou ship-borne application subsystem through a Beidou satellite link, and communicates with the AIS ship-borne application subsystem through an AIS base station link. A shore-based information processing center can timely judge whether received visibility information is abnormal or not, people are timely reminded that the ships are about to or enter a fog area by setting visibility alarm level, alarm modes and transmitting modes, the navigation capacity of the ships in fog is improved, economic loss caused by navigation delay due to the fog is reduced, and marine accidents caused by the fog are prevented.
Description
technical field [0001] The invention relates to a ship fog navigation system, in particular to a ship fog navigation safety navigation enhancement system in a port. Background technique [0002] In port waters, once the visibility drops to a certain level, the Vessel Traffic Management System (VTS) center will issue a suspension notice to guide ships to drop anchor nearby to avoid fog. Due to poor visibility in ports, large ships are suspended or stalled, which affects port production and poses severe challenges to water traffic safety supervision. With the development of communication and navigation technology, ships are equipped with GPS locator, ARPA radar, very high frequency (VHF) communication, ship automatic identification system (AIS) and other equipment, combined with shore-based navigation support system and VTS navigation services, to improve It ensures the safety of the ship when navigating in poor visibility waters. [0003] However, the fog in the port is not...
