Design And Implementation Of Warship Network Simulation System Software Based On FFmpeg

With the rapid development of technology,the data transmission between equipment on warships is more diverse and complex.As the basic platform for information transmission of various systems on warships,the demand for data exchange and information sharing undertaken by ship networks is increasing day by day.Due to the various types of equipment on warships and the different data formats generated by different equipment,direct warship network design requires a lot of financial and material resources.Therefore,effective verification tools are needed to simulate multiple data streams.Come to study the information interaction of the warship network.This paper puts forward the scheme of the warship network simulation system,and establishes the simulation environment to obtain the performance index of the warship network,which can assist the design and optimization of the warship network.This paper clarified the requirements of the software,and carried out detailed algorithm and interface design on this basis.Based on this,the design completed the development of audio and video streams,data stream code development tasks and software visualization interface development,thus building the entire software.The specific work content of this paper is as follows:(1)This article gives a more detailed introduction to the research status of domestic and foreign ship networks.On this basis,the key technologies of warship network simulation simulation system software—Iperf 3.0,FFmpeg multimedia processing framework,Qt program development framework and TCP/IP network protocol are studied in detail.(2)Aiming at the functional requirements and non-functional requirements of warship network performance simulation software,this paper combines specific project requirements and proposes a design scheme based on the FFmpeg multimedia processing framework.This solution uses FFmpeg to collect data from the device,encodes and transcodes the data,and then adjusts the network bandwidth of a specific path through Iperf 3.0,builds the server and client according to the TCP/IP protocol,and simulates the data transmission function in the warship network.(3)This article performs functional tests on the software completed on the basis of this scheme.Through data acquisition,data transcoding and data transmission function tests,it is verified that this software can well record the network performance parameters in the network simulation process.The test results show that this design scheme can achieve the requirements of warship network simulation,meet the performance indicators,and can run well and stably on other computer equipment.
