Node access method and device for Zigbee network

Abstract

The invention discloses a node access method and device for a Zigbee network. The method comprises the following steps: a coordinator broadcasts the node information of a node to be accessed in the Zigbee network during access; a routing node receives the node information, writes the node information to a preset address pool, and opens the function of allowing to access the network; the node to be accessed broadcasts a network access request beacon frame to the Zigbee network, wherein the network access request beacon frame includes the node information of the node to be accessed; the routing node that receives the network access request beacon frame matches the node information of the node to be accessed with the node information in the own address pool, and sends a response frame to the node to be accessed when the matching is successful; and the node to be accessed receives the response frame, selects a destination routing node from the received response frame, and accesses to the destination routing node. According to the node access method and device disclosed by the invention, the problem that the Zigbee network address can be correctly assigned even when the keys are different can be solved, and the data interaction of illegal equipment can be avoided from the source.

Description

technical field [0001] The invention belongs to the technical field of smart home, and in particular relates to a Zigbee network node access method and device. Background technique [0002] ZIGBEE technology uses 802.15.4 to define the physical layer and MAC layer, and supports Mesh topology. It has the characteristics of large network capacity, excellent network topology capability, simple network deployment, and low power consumption. Its coverage in the field of the Internet of Things has also spread rapidly, and its application occasions have gradually covered the field of household appliances from the field of urban construction. [0003] Home appliances of different home appliance manufacturers usually have their own communication or control protocols. In order to realize the interconnection and interoperability of devices from different manufacturers, all major smart home application manufacturers are moving closer to a certain standard protocol. [0004] However, ...

AI Technical Summary

Problems solved by technology

[0006] Although the ZIGBEE protocol itself also has an encryption mechanism, devices with different keys cannot communicate normally, but its encryption mechanism works on the APS layer, so even if the keys of the two devices are different, the network address can be correctly assigned, the difference lies in the devices with different keys Incapable of normal data interaction, ZIGBEE technology also withdraws devices with different keys that are correctly assigned addresses

Therefore, although technologies such as short-distance networking and button networking can alleviate unnecessary troubles to a certain extent, they cannot solve fundamental problems, such as: residential owners separated by a wall, rogue nodes that frequently initiate network access requests, etc.
