A stable and effective low-cost zigbee network node management method

Abstract

The invention discloses a stable effective low-cost management method for Zigbee network nodes and relates to the technical field of management of the Zigbee network nodes of Internet of Things. According to the management method, the defects that the cost is high caused by high requirement on hardware performance, and a network is too busy and is slow in response caused by excessive large initialized registration data volume in the existing Zigbee network coordinator are overcome. The management method comprises the following steps of respectively storing sequence numbers of all Zigbee network nodes in the Zigbee network coordinator; when external user equipment and the Zigbee network coordinator establish the connection and carry out initialization, returning the number of the stored sequence numbers to the external user equipment by responding to a request of the external user equipment by the Zigbee network coordinator; controlling the Zigbee network coordinator to query all the Zigbee network nodes one by one according to the returned number of the sequence numbers and a defined network management method by the external user equipment; collecting and storing parameter information of all the Zigbee network nodes by the external user equipment through the Zigbee network coordinator. The data processing load of the Zigbee network coordinator is shared, and network broadcast query is performed without using the Zigbee network coordinator, so the technical defect that Zigbee network broadcast data are easily conflicted is overcome.

Description

technical field [0001] The invention relates to the technical field of Zigbee network node management of the Internet of Things. Background technique [0002] The network protocol used in existing smart lighting and smart homes is mainly Zigbee. Because the Zigbee protocol has more detailed regulations in the network layer, data link layer, and physical layer. This means that as long as the network nodes comply with the Zigbee protocol, they can successfully form a network and join the network. If you want to realize the interconnection and intercommunication of various network nodes, you also need the upper layer protocol of Zigbee. But on the application layer above the network layer, there are basically some relatively open definitions, such as ZLL, HA and other profiles, which only define specific functional interfaces, but do not stipulate how each network node is effectively organized and managed. Realization is basically left to each manufacturer to solve by itself...

Problems solved by technology

[0004] In summary, the purpose of the present invention is to solve the existing Zigbee network coordinator hardware performance requirements are high, resulting in high cost, and the amount of initial registration data is too large, resulting in too busy a slow response to the technical deficiencies of the network, and propose a stable Effective and low-cost Zigbee network node management method
