Internet of things support system based on two-layer overlay network and realization method

The invention discloses an internet of things support system based on a two-layer overlay network and a realization method, and is particularly applied to the following internet of things system modeling and development, namely, an internet of things application has complex application scenes for complex diverse resources. According to the internet of things support system based on the two-layer overlay network and the realization method disclosed by the invention, a user can expand functions of a resource module and organize the functions of resource application scenes according to specifications defined by the invention; concepts of "two networks", namely a resource control network and a fusion network, are introduced by the method, so logical systems on two levels of access control and application scheduling to internet of things resources are decoupled, wherein a hyper-resource graph model and an EITP (Extract and Injection Transfer Protocol) protocol interconnection technology are adopted by the resource
