the second slave node data communication module is used for processing the data request message sent by the master node and constructing and sending a data response message or an active reporting message;
the master station or the concentrator transmits file management information and file membership information to the master node, the master node forwards the file membership information to the first class slave nodes, and the first class slave nodes store the corresponding relations of the corresponding second class slave nodes; the archive management message includes: the archive information of the first class slave node and the second class slave node; the archive membership message includes: a subordinate relationship between the first class of slave nodes and the second class of slave nodes;
the first class slave node sends a network access request message to the master node;
after receiving the network access request message of the first type slave node, the master node replies a network access request response message and records the network access state of the first type slave node;
the master station or the master node sends information of a second class slave node subordinate to the first class slave node which is accessed to the network;
the second class slave node sends a connection request to the first class slave node, and judges that the connection is successful after receiving the connection confirmation message of the first class slave node;
and after the master node receives the connection success of the second class slave node reported by the first class slave node, the master node records the connection state information of the second class slave node.
9. A power line carrier hybrid networking system, comprising the master node connection management apparatus of claim 6, the first slave node connection management apparatus of claim 7, and the second slave node connection management apparatus of claim 8.
