1. autonomous network-building method that is used for the electric energy meter wireless kilowatt meter reading-out system, the node in this system comprises concentrator and acquisition terminal, it is characterized in that may further comprise the steps:

  • Node periodically sends neighbours'"'"' exchange command with broadcast mode in network;

    Each node receives neighbours'"'"' exchange command, the node address that sends neighbours'"'"' exchange command is added in self neighbor table of each node;

    But each node is confirmed and the whether two-way communication of certain node according to neighbours'"'"' exchange command;

    But if with certain node two-way communication, judge then whether this node has added network;

    If this node has added network, be that father node is established to the up route between concentrator then with this node;

    The node of above-mentioned firm adding network sends routing update order with mode of unicast to concentrator through self father node, sets up by concentrator to this just descending route of adding network node;

    This firm adding network node independently adds network and finishes;

    Repeat above-mentioned steps, circulation is carried out, and adds network until all nodes.
