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.
