Abstract: This paper analyzes the development relationship between data link and war form, and makes an in-depth analysis of the data link 2.0 main structure of internet of weapons, combining the development of internet of things, cloud computing, artificial intelligence and other new technologies. The technical development ideas such as forward decision-making processing, machine mutual recognition, intelligent micro-terminal control are proposed. Based on the core characteristics of full-scale operational element interoperability, and efficient flow of reconnaissance-control-attack-evaluation information, the intelligent cross domain killing network is constructed to realize gathering energy from network information systems to the end of the battlefield, supporting the formation of discovery or destruction capability.
