Description

Networking method, control device and control equipment Technical Field The application belongs to the technical field of power carrier communication, and particularly relates to a networking method, a control device of a sub-node STA, control equipment and a machine-readable storage medium. Background In the power line carrier communication, or the dual-mode communication combining the power line carrier communication with other communication modes, or the multi-mode communication combining the power line carrier communication with other communication modes, the STA receives beacons from CCO, PCO and the network-accessed STA, analyzes a list which can be used as proxy nodes according to the beacons, and then screens candidate proxy nodes in sequence according to the following sequence, wherein the candidate proxy nodes are low-level priority, proxy node priority and high-signal-to-noise ratio, and an association request is sequentially initiated to the candidate proxy nodes according to the sequence until the association is successful. According to the above method, if there are too many low-level nodes, and when the communication quality between the STA and the low-level nodes is poor, the STA continuously tries to use the low-level nodes as agents, but fails to network, resulting in too long network time. In addition, if a multi-network environment exists, the STA needs to switch to other networks after the association request number of the current network reaches the set maximum request number or the networking attempt time exceeds the set maximum duration. However, if there are too many low-level proxy nodes, the number of association requests initiated to these low-level nodes may exceed the set maximum number of requests or the total duration of the association requests initiated to these low-level nodes exceeds the set maximum duration, so that the high-level nodes cannot be selected as proxies, and the networking efficiency is reduced. Disclosure of Invention An object of the embodiments of the present application is to provide a networking method, a control device of a sub-node STA, a control device, and a machine-readable storage medium, so as to solve the technical problem in the prior art that networking efficiency is low when candidate proxy nodes are screened for networking according to low-level priority, proxy node priority, and high signal-to-noise ratio.

In a specific embodiment of the present application, the attempting mechanism further includes, if the association attempt of each level is completed and the association with any candidate agent node is not successful, directly jumping or selecting a new network to be accessed, and jumping to the lowest level and the highest level of the candidate agent node which determines that the association request is not initiated in the network to be accessed. In a specific embodiment of the application, the method for initiating the association request to at least one candidate agent node in the current hierarchy comprises the steps of selecting a plurality of target agent nodes with communication states superior to those of other candidate agent nodes which are not selected and/or with equipment roles as relay nodes PCOs from the candidate agent nodes in the current hierarchy based on the communication state information and the equipment role information of the candidate agent nodes in the current hierarchy, and sending the association request to at least one target agent node. In a specific embodiment of the application, based on the communication state information and the equipment role information of each candidate agent node in the current hierarchy, selecting a plurality of target agent nodes with communication states superior to those of
