Abstract

The present invention discloses a target simulator real-time drive system based on a DVI interface of a graphics card. The system comprises: a DVI transmission interface, used for establishing a data communication with a graphic workstation and a target simulator; a synchronous transmission control module, used for sending a simulation start signal to a dynamic scene image simulation module based on a field frequency signal output by the DVI transmission interface, and establishing synchronous data transmission with the target simulator; and the dynamic scene image simulation module, used for performing simulation analysis on to-be-tested dynamic scene data acquired from an external device based on the simulation start signal, and storing simulation image data into a frame cache. The present invention further discloses a target simulator real-time drive method based on a DVI interface of a graphics card. The technical scheme provided by the present invention shortens radiation scene output delay, ensures delay stability and thus greatly improves confidence of semi-physical dynamic scene simulation.

Description

technical field

[0001] The invention relates to image data transmission, in particular to a real-time driving system and method for a target simulator based on a graphics card DVI interface. Background technique

[0002] Dynamic image scene simulation is an important part of hardware-in-the-loop simulation experiment. Graphics computer graphics card GPU has powerful graphics rendering and parallel computing capabilities. At present, mainstream complex scene modeling software platforms at home and abroad are all based on the graphics engine of the graphics card. The simulation scene image generated by the graphics computer is output to the target simulator through the standard DVI interface of the graphics card to refresh and generate the radiation scene. However, since DVI follows an industry standard for video transmission, there is an inherent transmission delay. After testing, when the frame frequency is 100Hz, from the image generation computer receiving the simulation...
