System of internet of things and safety management method for system of internet of things

The invention provides a system of the internet of things and a safety management method for the system of the internet of things to solve the problem of integration of the internet of things with the telecommunication network. The system of the internet of things comprises a local internet of things, an access network, a core network and a server of the internet of things. The local internet of things comprises a router of the internet of things and node equipment, and the node equipment is connected with the router of the internet of things and in communication with the access network through the router of the internet of thing. The access network is used for transmitting communication data or commands between the local internet of things and the core network. The core network is used for switching of communication data or commands between the access network and the server of the internet of things and also used for transmitting communication data or commands among different access networks. The server of the internet of things is used for safety certification of the router of the internet of things and the node equipment of the local internet of things. Organic integration of the internet of things with the current telecommunication network containing the mobile communication network can be realized with the telecommunication network needing no great change.
