10. a low-voltage power carrier communication network optimization system comprises: host node and a plurality of from node, it is characterized in that, and described host node comprises: networking commands sending module and information extraction distribution module;
Described networking commands sending module is for traveling through one-level from node, and usings one-level and issue networking commands toward next stage from node as relaying from node, and described networking commands comprises from node carries out time and the unknown node number that channel is seized needs;
Described information extraction distribution module is for according to the described networking request message sent from node, extracts describedly from address of node and neighbours' reliability information distribute its network identity, completes the networking of primary node and secondary node;
Describedly from node, comprise that channel seizes module and networking request message sending module;
Described channel is seized module and is carried out channel for the networking commands issued according to host node and seize; Described networking request message sending module is for sending the networking request message to described host node.
11. a kind of low-voltage power carrier communication network optimization system according to claim 10, it is characterized in that, described host node also comprises: reliability value table module and router table means, described reliability value table module is for setting up a reliability value table, and storing the reliability value that each is communicated by letter each other from node, the described value of the reliability from node size is decided by this signal to noise ratio from node and its neighbor node; Described router table means is used for preserving the routing iinformation of current system, and according in described reliability value table each from node reliability each other, calculate the described optimal path from host node to each node, and regularly upgrade this routing table.
