Research On Information Storage Technology In Fire Control System Operational Test

In recent years,the weapon equipment operational test has become an important direction of transformation of traditional weapon test under the background of contemporary new military revolution.It is also an effective way to carry out a comprehensive evaluation of the actual combat capability of equipment under the current information era.In order to realize the dream of the military power,it has become one of primary tasks for military construction by means of developing and perfecting the practice of the military equipment operational test.For purpose of obtaining a solid and reliable basis,the system of operational test was analyzed and perfected and actual combat effectiveness was evaluated.Therefore,it seems particularly essential to store images on the spot during wartime at high speed,in real time and in intact state in the early stage of operational test activities.Combining with the requirements of standardization,miniaturization and high stability of wartime on-the-spot image information storage system in battle-test application,the thesis proposed storage technical route of Xilinx Zynq series chip Zynq-7015 and SSD,applied FPGA+ARM architecture in Zynq-7015 chip comprehensively,studied the key technology of the image storage system in wartime field.This paper analyzed the overall structure of storage system,taking MC1360 camera as video source,and finished the design of image acquisition module in FPGA and through the analysis and research of SATA3.0 protocol of each layer function and work mode,completed the design of SATA controller,successfully achieving the SATA interface storage of high-speed image;by building embedded Linux system platform and using the DDR3 controller to achieve high data stream cache,the thesis managed the storage disk file through the file management system in ARM;by using the interactive terminal Qt design,achieved the function of on-the-spot image displaying in real time and controlling during wartime.Finally,functional simulated experiment of the system was conducted through the experimental platform.The experimental results showed that this system can realize the functions of operational test image information acquisition and storage,and the thesis aimed to be of some help for further research and test evaluation of weapon combat effectiveness in the future.
