In order to solve the problem of networking and centralized management of massive ZigBee nodes, this study proposes a multi-ZigBee network structure management design scheme based on Internet server. The system divides the mass nodes into multiple ZigBee network structures, and there is no coupling between each network, which can get rid of the distance limit of wireless transmission. In addition to the terminal node and the ZigBee coordinator, each independent ZigBee network adds a controller that can access the Internet to form an intranet structure. The ZigBee nodes use Z-Stack protocol to realize self-organizing network function, and the controller is mainly used to realize communication between nodes and servers. The proposed concept of the central server as the core of the external network structure is used to maintain the state information of all nodes in the central database and provide Web services to clients. The client's query or control operations on any node are completed by the central server agent. The test shows that the system is reliable and expandable, and has certain reference value.
