[0013] In order to more clearly illustrate the technical solution provided by the present application, the following is a brief introduction to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present application.

[0016] Figure 3 This is a schematic diagram of the structure after adjustment of the initial model of this application. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0018] A planning parameter adjustment method based on graphics displays data in a graphical manner by setting a graphic display unit. When making adjustments, the adjustments can be made directly and intuitively on the graphics without the need for manual parameter configuration. The adjustment time is short and the adjustment efficiency is high.

[0019] like Figure 1 As shown, the specific steps include:

[0020] Step S100, reading the input parameters required for attack zone calculation in the planning interface;

[0021] like Figure 2 As shown, step S200, calling the fire control solution model, calculating the attack zone parameters, inputting the attack zone parameters into the graphic display unit, and the graphic display unit displays the initial model according to the attack zone parameters;

[0022] The parameters that need to be input include A, target point; E, target azimuth line; F, attack entry velocity vector symbol; G, theoretical maximum attack distance ring; I, attack area.

[0023] In the initial model, the attack velocity vector is collinear with the target azimuth line, the attack zone is fan-shaped and located within the theoretical maximum attack distance ring, and the outermost end of the attack zone is adjacent to the annular surface of the theoretical maximum attack distance ring.

[0024] The fire control solution model is an existing model and will not be described in detail here.

[0025] Step S300, manually dragging the target azimuth line to rotate around the target, causing other parameters in the initial model to change accordingly, such as the carrier aircraft attack entry speed azimuth, speed direction and position;

[0026] In the process of manually dragging the target azimuth line to rotate, the arrow end point of the attack entry velocity vector symbol is always connected to the theoretical maximum attack distance ring, which means that the combat aircraft is about to enter the attack zone. When the combat aircraft continues to fly, it reaches the attack zone and conducts combat.

[0027] Manual dragging can be done by clicking and dragging with the mouse or by pressing a combination of keys.

[0028] There are two specific methods in which the endpoint of the arrow of the attack entry velocity vector symbol is always connected to the theoretical maximum attack distance ring. Of course, it is not limited to these two methods. Other methods that can achieve this effect are within the protection scope of this application.

[0029] The first one is:

[0030] The coordinates of each point on the theoretical maximum attack distance ring and the coordinates of the arrow endpoint of the attack entry velocity vector symbol are obtained. After manually dragging the target azimuth line to rotate, the new coordinates of the arrow endpoint of the attack entry velocity vector symbol are obtained. The fire control solution model calculates the minimum value of the coordinates of the arrow endpoint of the attack entry velocity vector symbol and the coordinates of each point on the theoretical maximum attack distance ring, and moves the coordinates of the arrow endpoint of the attack entry velocity vector symbol to the coordinate position of the minimum distance of the theoretical maximum attack distance ring.

[0031] By finding the minimum distance between F and G during the rotation process, the attack can be accurately positioned to enter the velocity vector symbol.

[0032] The second one is: obtain the distance between the coordinates of the endpoint of the arrow of the velocity vector symbol and the target point. After manually dragging the target azimuth line to rotate, the fire control solution model always keeps the distance between the coordinates of the endpoint of the arrow of the velocity vector symbol and the target point unchanged during the calculation process until a new graph is formed.

[0033] By keeping the distance between F and A unchanged during the rotation, the attack can be accurately positioned at the velocity vector symbol.

[0034] Step S400, calling the fire control solution model to obtain parameter changes, such as azimuth, speed direction and position changes, and re-calculating the attack zone parameters;

[0035] like Figure 3 As shown, in step S500, the fire control solution model obtains the solution result and inputs the solution result to the graphic display unit. The graphic display unit adjusts the graphics in real time according to the input parameters, and the relevant elements of the screen change accordingly to form a new graphic interface.

[0036] In the parameter adjustment process of attack planning, the input parameters are set first, the parameters are solved by the fire control solution model, and then displayed in a graphical way. Then the graph is adjusted by manually rotating the graph to change the parameters in the graph, and then a new graph is obtained by solving the model. Compared with the manual input parameter method, it is simpler and more convenient, and the parameters can be adjusted quickly to shorten the planning time. At the same time, the way of changing the graph can intuitively reflect the impact of parameter adjustment on the planning results. In addition, under this parameter adjustment method, the human-computer interaction experience is better.

[0037] As a specific implementation, a graphics-based planning and parameter adjustment system includes: a parameter reading unit, a fire control solution model and a graphics display unit.

[0038] The parameter reading unit is used to read the input parameters required for the attack zone solution of the planning interface and output them; the fire control solution model is used to receive the input parameters read by the parameter reading unit, calculate the attack zone parameters, and output the attack zone parameters; the graphic display unit is used to receive the fire control solution model or the adjusted attack zone parameters, and display the initial model or the adjusted model according to the parameters.

[0039] Through the cooperation between the graphic display unit and the fire control solution model, manually adjusted graphic changes can be quickly solved, thereby achieving timely adjustment of the graphics, and the driver can quickly obtain the adjustment parameter information for attack operations.

[0040] Preferably, the graphic display module includes a display module, an operation module, and a parameter output module; the display module is used to obtain the parameters after the model is solved and display the corresponding graphics of the parameters, the operation module is used to obtain the operation instructions and adjust the displayed graphics in real time, and the parameter output module is used to obtain the graphic parameters in real time and transmit the graphic parameters to the solved model.

[0041] Through the cooperation of the display module, the operation module and the parameter output module, the graphics in the display module can be quickly adjusted and displayed.

[0042] Preferably, it also includes a data storage unit, which includes a reading unit and a writing unit. The writing unit first stores a set of initial data, and then overwrites the original data each time a new set of data is obtained until the data is no longer updated, and the final data is stored; the reading module is used to call out the final data according to the operating instructions and send it to the graphic display unit for display.

[0043] By using data overwriting to obtain the latest and final data, data redundancy can be quickly eliminated, data errors can be prevented, and processing efficiency can be improved.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
