Embodiment Construction

[0013] The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings:

[0014] A ship operation map projection system oriented to combat navigational mapping, such as figure 1 and figure 2 As shown, it includes a projection device host, a projection device, a mechanical rail, and a mechanical rail controller. The projection device host is connected to the navigation workbench through an Ethernet interface for receiving ship operation maps and position information sent by the navigation workbench; the projection device host is connected to the chart plotter through a serial port, and the projection device host It is controlled by connecting with the mechanical rail controller through the I / O interface. The projection device is installed on the mechanical guide rail below the chart plotter, and the projection device moves on the mechanical guide rail under the control of the mechanical guide rail controller, so that ...

Abstract

The invention relates to a navigation operation drawing projection system for battle navigation plotting, and the system is technically characterized in that the system comprises a projection device main unit, a projection device, a mechanical guide rail, and a mechanical guide rail controller; the projection device main unit is connected with a navigation workbench, and is used for receiving a navigation operation drawing and position information transmitted by the navigation workbench; the projection device main unit is connected with a sea chart plotting platform, and is connected with the mechanical guide rail controller, and controls the mechanical guide rail controller; the projection device is installed on the mechanical guide rail below the sea chart plotting platform, and the projection device is controlled by the mechanical guide rail controller to move on the mechanical guide rail, and enables a ship operation chart to be projected to a paper sea chart. The optical projection technology is used for projecting the ship operation chart to the paper sea chart, and the system obtains the moving conditions of two sides of a battle through multiple targets on the paper sea chart, achieves the target plotting function for the battle navigation operation, improves the practicality of ship operation through the paper sea chart, is simple in structure, and is greatly improves the usability.

Description

Technical field [0001] The invention belongs to the technical field of nautical plotting, in particular to a ship operation map projection system oriented to combat nautical plotting. Background technique [0002] Ship maneuvering map is one of the main tools for navigators to draw and calculate ship maneuvers. It is composed of several equally spaced concentric circles and radiation lines drawn from the center of the circle. In addition, when conducting radar plotting during ship collision avoidance, It is also widely used to draw calculation diagrams of ship operations. At present, the navy of our country mainly completes the ship operation map through the navigation workbench. Its advantages are that the drawing is simple and fast, the map area is small, and it is easy to use on the command platform. Due to the lack of information credibility and untimely update of electronic charts (navigation workbench) compared with paper charts, there is little target information on the s...
