[0025] figure 1 The topological diagram of the communication subnet on the smart grid is shown. The communication subnet on the smart grid includes a central node and a node, and the central node sends data packets from other subnets on the smart grid to the node. When data packets arrive at the central node, they are first queued. Each independent queue corresponds to a node. The task of the central node is to arrange these data packets to reach the designated node in time through the power line.
[0026] figure 2 Shows a flow chart of a power carrier communication method, the specific process is as follows:
[0027] Step S1, collecting information, acquiring pilot signals and obtaining node status information according to the pilot signals, and then sending the node status information, including:
[0028] The physical layer receives the pilot signal from the node and collects the status information of the node. The node state information includes the node's data packet transmissi...
