In order to carry out joint training better, a guidance and control system based on internet of things (IOT) is established. On the basis of functional requirement analysis, this paper researched the overall structure of the system, and made the system functional modules integrate into the perception layer, network layer and application layer such 3-layer architecture of IOT, then the overall system is covered with IOT, become a specific entity of internet of things. By discussing the system hierarchically, we give out the general idea for designing the system based on IOT. This paper studied and analyzed the framework and technical architecture of the guidance and control system, which established a theoretical foundation for the future system development.
