Abstract

The invention discloses an electronic chart-based auxiliary information indicating system for navigation safety in complex sea areas. The system comprises an information processing platform, wherein adata storage and inquiry unit and a navigation safety auxiliary unit are instantiated inside the information processing platform; the navigation safety auxiliary unit is used for obtaining navigationsafety auxiliary information from the data storage and inquiry unit and inserting the information into an electronic chart in a form of independent layer; a corresponding object mark is generated ona display interface of the electronic chart; and when an externally input touch screen instruction on the object mark is received or navigation information indicates that a ship enters a key area, thecorresponding navigation safety auxiliary information is displayed on the electronic chart. According to the invention, the graphic integrated display of the various navigation safety auxiliary information is achieved based on the electronic chart, so that the various navigation safety auxiliary information can be timely, comprehensively, intuitively and conveniently learned about by seafaring personnel; and various navigation auxiliary plotting can be achieved, so that decisions on location, navigation, risk avoiding and sheering can be fast and correctly made.

Description

technical field [0001] The invention belongs to the technical field of navigation information application, and more specifically relates to an electronic chart-based auxiliary information indication system for navigation safety in complex sea areas. Background technique [0002] Complex sea areas mainly refer to sea areas where the hydrological and meteorological conditions are complex and changeable, the navigable waters are narrow, the waterways are multi-turned and converged, the obstacles are many and complex, and various types of ships are active, and the navigation environment is complex, which makes safe navigation difficult, such as Zhoushan and Penghu Sea Area, Seto Inland Sea in Japan, Strait of Malacca, Great Barrier Reef in Australia, Baltic Sea in Europe, etc. Such sea areas are prone to navigation safety accidents such as collisions, grounding, and grounding. Taking Zhoushan sea area as an example, there were 27 collision accidents between commercial ships and ...
