Embodiment Construction

[0027] The structure of the present invention will be further described below in conjunction with the accompanying drawings and through embodiments. It should be noted that this embodiment is illustrative rather than limiting.

[0028] A paper and electronic chart fusion method applied to navigation auxiliary operations, please refer to Figure 1-5 , the invention point is: the operating platform of the paper-electric chart fusion method is a ship integrated navigation system. One of the main functions of the ship integrated navigation system is to provide navigation assistance for users. The traditional ship integrated navigation system is equipped with separate and independent paper charts and electronic charts. At present, the two auxiliary means are used separately, but the present invention integrates the two auxiliary means to improve the auxiliary efficiency of navigation operations, and specifically includes the following steps:

[0029] Step 1: Build a set that can ...

Abstract

The invention relates to a paper-electricity chart fusion method applied to marine navigation auxiliary operation, which comprises the following steps of: 1, constructing a plotting device capable of picking up longitude and latitude on a paper chart, the plotting device comprising a digitization board, a light spot indication structure and a picking-up terminal; mapping longitude and latitude coordinate values on the whole sheet of the paper chart to a digitization board; after the relative positions of the paper chart and the digital board are fixed, reading the latitude and longitude of each waypoint of a planned route on the paper chart through a pickup terminal, and forming digital information; 2, sending the digital information to an electronic chart terminal, and enabling the electronic chart terminal to verify the safety of an artificially made planned route; 3, under the safety condition, according to the formulated planned route, otherwise, modifying the planned route and sent to the plotting device, enabling the plotting device to indicate each waypoint for modifying the planned route on the paper chart, and enabling the navigator to modify the planned route on the paper chart and sail according to the modified planned route. The auxiliary efficiency of navigation operation is improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary decision-making for ship navigation and navigation, and in particular relates to a paper-electric chart fusion method applied to auxiliary operations of navigation and navigation. Background technique [0002] Navigation is an ancient art. Nautical navigation has developed from observing the sun and stars in ancient times to pointing north to a modern ship comprehensive navigation system covering various technical disciplines. Its mission has also expanded from a single direction for ship navigation to Support ships to perform various tasks. [0003] For a long time, nautical personnel mainly relied on paper charts for auxiliary navigation operations, and formulated and modified planned routes on paper charts according to the navigation plan. The tools used were mainly pencils, rulers, etc., and planned routes could not be stored or shared. . With the development of information technology, ele...
