Background technique

Inland waterways belong to the category of narrow waterways. Due to differences in the navigation environment, the navigation conditions are much more complicated than at sea. With the development of the shipping economy, more and more river-sea direct ships are going to the ports along the rivers for loading and unloading operations. If the captain and driver of the sea-going ship enter the inland waterway for the first time, they do not understand the inland waterway and navigation characteristics, do not carefully check the information of the voyage section, study the situation of the waterway, and are not sufficiently prepared for potential dangers and emergencies, which will lead to urgent situations one after another. to. Due to the influence of various environmental factors, the inland waterway is changing to varying degrees all the time. Therefore, even if the captain and driver of the sea-going ship have an in-depth understanding and preparation of the waterway in advance, the ship is in the actual sailing process.
