Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 As shown, it is a flow chart of a method for a power line carrier ad hoc network in an embodiment. The power line carrier ad hoc network method includes:

[0044] Step 102, after a sub-node that has not joined the network receives the network access permission command frame, acquires the link communication status between the sub-node and surrounding nodes that have already joined the network.

[0045] First of all, after the master node starts the networking program, the master node sends a network access permission command frame, and starts the network access program of t...

Abstract

The invention relates to a power line carrier ad hoc network method and system. The method comprises the steps that after a non-access child node receives an access-allowing order frame, link communication states of the child node and surrounding accessed nodes are obtained; according to the link communication states, accessed nodes which have the communication quality meeting preset communication requirements, the minimum levels and the best communication quality on uplinks and downlinks are selected, the selected accessed nodes are used as father nodes of the child node; an access request is sent to the father nodes, returned access response is received, and networking is not over until nodes for networking are all accessed. According to the power line carrier ad hoc network method and system, the problem of link asymmetry is solved, data double-way communication is achieved, a main node does not need to search child nodes one by one in a traversal mode, overhead time is saved, and flexibility is high.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and system for an ad hoc network of power line carriers. Background technique [0002] Power line carrier communication is a unique communication method for power systems, and it is a technology for transmitting analog or digital signals through carrier waves. The biggest advantage of the power line carrier is that there is no need to re-establish the network, low cost, and convenient layout and maintenance. In the traditional power line carrier system, because the distance between the concentrator and some sub-nodes is far away, communication needs to go through one or more levels of relays. Generally, a routing path for communication between all sub-nodes and the master node is established in advance. When there is a communication demand , directly use the pre-established path for data transmission. [0003] However, the power line is not a good communication medium, and...
