Electronic auxiliary method, device and system for nautical drawing and calculation

Abstract

The invention discloses an electronic aiding method, device and system for navigational calculation, the method includes: determining the type of navigational calculation problem to which the target problem belongs, and searching for the navigational calculation problem to which the target problem belongs from a geometric template library A type-matched geometric template, and solving the target problem according to the matched geometric template. The application of the invention can overcome the shortcomings of the existing electronic tools for navigation auxiliary drawing and calculation in terms of intuitive interaction and flexible customization.

Description

technical field [0001] The invention belongs to the technical field of navigation and navigation, and in particular relates to electronic aided navigation calculations, in particular to an electronic auxiliary method, device and system for navigation calculations. Background technique [0002] During the voyage of the ship, the nautical operators need to complete various navigation calculation problems and solve the corresponding maneuvering parameters to meet the commander's decision-making needs, such as approaching or leaving the target ship, occupying or maintaining a specific position, etc. At present, the commonly used method is to carry out manual work on the drawings. The process is as follows: navigators use drawing tools such as pencils, parallel rulers, protractors, and rail divisions to draw known conditions as geometric elements such as points, lines, and circles on the drawings. , and then perform a series of specific drawing operations, such as translation, co...

Problems solved by technology

[0005] However, these electronic tools are all based on analytical calculation models, and their output results are usually the solutions of multivariate equations set up based on the relationship between parameters, which cannot intuitively show the relationship between known conditions and output results, and the result graphics are only result values. A read-only representation of the , which cannot be used interactively

Therefore, navigators cannot deeply understand and grasp the situation, compare and analyze maneuver parameters and more complex maneuver schemes by inspecting the intermediate process and visually fine-tuning the resulting graphics

In addition, these electronic tools can only solve the problem types that have been modeled and programmed, and for other problem types, even if the program interface is open, it is difficult for navigators to grasp
