Problems solved by technology

The former is limited by the fact that the overall calling process is too high-level, and the corresponding underlying functions on the STK side cannot be seen. The range of commands that can be realized is limited, error correction is difficult, and the entire calling system is cumbersome and unstable.

specific Embodiment approach 1

[0068] Specific implementation mode one: as Figures 1 to 13 As shown, the description of the design method of the display system based on Labview and STK in the present invention is as follows in the present embodiment:

[0069] Labview is a fast programming language based on C++ developed by NI Corporation of the United States. It is currently ranked about 30th in the world's commonly used languages. Although it is a graphical programming language, for engineers who have used textual programming languages ​​for a long time, it requires a process of thinking conversion from text to graphics, but after getting used to the graphics of Labview, they will gradually discover its powerful advantages. First of all, for those engineering projects with high interface requirements, Labview has a unique advantage of interface customization; secondly, the state machine and queue message processor model based on loop structure, event structure and sequence in Labview provide engineering r...

Abstract

A design method of a display system based on Labview and STK relates to a design method of a display system. The purpose of the present invention is to realize the display control of the STK end by the Labview end by calling the DLL. The method is based on the display function of STK and the engineering design function of Labview, through the Connect module of STK, the VISA interface of Labview and the establishment of a state machine project, to realize the function of using Labview to control STK between different terminals; the method realization process is: Create a STKCONNECT.dll that can be called by Labview; serial port transmission process; display system main body design and implementation, use event structure and loop structure nested state machine as the structure of the entire program display system main body. The present invention is suitable for the actual requirement that the control terminal and the display terminal are separated.

Description

technical field [0001] The invention relates to a design method of a display system. Background technique [0002] Labview is a graphical programming language. Compared with text programming language, its biggest advantage is the powerful front panel design function. Satellite Toolkit STK (Satellite Tool Kit) is a software developed by AGI Company for 3D simulation and system analysis. It is widely used in aerospace, intelligence, radar, electronic countermeasures, missile defense and other fields. STK contains advanced analysis modules, high-precision orbit generation functions, long-period orbit predictors, life cycle, terrain and high-resolution maps, making it possible to provide realistic 2D and 3D visualization dynamic scenes and accurate charts, reports, etc. analysis results. There are currently two main ways to call STK with Labview as a third party. Use Labview's ActiveX plug-in and library function call node to call the corresponding plug-in and DLL in STK res...
