21) the main node performs communication tests of a power line carrier channel and a micropower wireless channel between specified nodes in the slave networking sub-nodes;
22) after receiving the data of the communication test of the main node or the relay sub-node, the sub-node carries out code returning on the test data;
23) after the main node receives the test return code, the main node fills in a communication relation sub-matrix table, whether communication information of all nodes in the communication relation sub-matrix table is completed or not is judged, if the communication information is completed, the node communication relation matrix table is updated, a communication path is obtained according to the communication relation matrix table, wherein the communication information in the communication relation sub-matrix table comprises the communication test times between the node and adjacent nodes, the success rate of uplink and downlink of power line carrier communication, the success rate of uplink and downlink of micro-power wireless communication and the information of the strength of wireless communication signals, and the communication relation matrix table summarizes the information of all the communication relation sub-matrix tables;
24) and the main node selects the communication path with the same test times and the highest communication success rate from the communication relation matrix table as the optimal path.
