Embodiment

[0020] see figure 1 , the figure includes electronic chart display module, electronic chart conversion module, electronic chart service module, electronic chart control interface module, electronic chart data processing module, electronic chart display module, electronic chart conversion module, electronic chart The chart control interface module and the electronic chart data processing module are respectively bidirectionally connected with the electronic chart service module. The electronic chart service module is the central processing mechanism of other modules and is responsible for the coordination of each module.

[0021] The electronic chart conversion module is responsible for converting S57 chart data into self-defined SENC chart data. The theoretical model of the S57 standard is generally expressed as "a real-world entity should be defined as a combination of the entity's spatial coordinate information and entity property description information ”, that is, use attri...

Abstract

The invention discloses an overlapping display system for an electronic chart and a radar echo. The overlapping display system comprises an electronic chart display module, an electronic chart conversion module, an electronic chart service module, an electronic chart control interface module and an electronic chart data processing module. The electronic chart display module, the electronic chart conversion module, the electronic chart control interface module and the electronic chart data processing module are respectively in both-way connection with the electronic chart service module. The electronic chart service module is a central processing mechanism for the other modules. The electronic chart conversion module is responsible for converting S57 chart data into customized SENC chart data. The electronic chart control interface module provides an electronic chart control interface and is communicated with the other modules by operating the electronic chart control interface. According to the overlapping display system for the electronic chart and the radar echo, the navigation safety is effectively improved, the target-discriminating capacity of a naval vessel during navigation or search task execution is strengthened, and the forceful guarantee can be visually provided for the naval vessel navigation through the overlapping display of the electronic chart and the radar echo.

Description

technical field [0001] The invention belongs to the field of navigation and navigation, in particular to an electronic chart and radar echo superposition display system. Background technique [0002] At present, all countries attach great importance to electronic nautical charts and their application systems, and invest a lot of money in research and development. Related international organizations have regulated electronic nautical charts since they were just emerging. The International Hydrographic Organization (IHO) established a special committee to study the standards and specifications of electronic charts and application systems. From the perspective of production and application of electronic charts, they successively developed S-52 "Content and Display Specifications for Electronic Charts" And S-57 "Digital Hydrographic Data Transmission Standard", etc. In order to promote the efficient, healthy and orderly development of electronic chart technology, the three majo...
