At present,traditional aids to navigation(AtoN)serve navigable ships through visual,radio and audio methods,but with the continuous changes in the navigation environment of the Yangtze River estuary,navigable ships have an increasingly urgent need to obtain navigational information,and the existing navigation AtoN can no longer fully meet the needs of ships for navigation support services.In order to enable navigable ships in the Yangtze River estuary to obtain more abundant and effective navigational aid information,the existing visual AtoN is modified and equipped with collection and transmission modules such as hydrology,meteorology and shipborne automatic identification system(AIS)on the basis of the existing navigation AtoN to form a multi-functional AtoN,which can realize real-time collection of hydrological and meteorological information,and use electronic fencing technology to directly broadcast various navigational aid and early warning information to the ships.To provide more digital safety information for ship piloting personnel in the waters of the Yangtze River estuary and reduce the occurrence of various ship accidents.
