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

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] First of all, the definition and construction idea of ​​the geometric template used in the present invention are briefly explained as follows:

[0057] For each type of navigation calculation problem, the known parameters and parameters to be obtained for each specific problem included are the same, such as the speed and heading of the target and the ship, and the difference lies in the different values ​​of the known parameters and the This results in a difference in the value of the parameter to be sought. The diagramming method for each type of nautical calculation problem is also the same, consisting of a finite, definite sequence of actions consisting of the same steps. Therefore, although the graphics of the calculation results of dif...

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...
