S104, generating an epitope information communication instruction by the intelligent management controller, and sending the epitope information communication instruction to the multi-path controller;
s105, the multi-channel controller receives the epitope information communication instruction and writes epitope information into the intelligent electric energy meter corresponding to the epitope;

S106, the intelligent management controller inquires whether the multi-channel controller completes the epitope writing task, if the epitope writing task is completed, the step S107 is executed, otherwise, the step S105 is executed continuously;

specifically, in step S105, the multi-path controller has written the epitope information into the electric energy meter corresponding to the epitope, so that the intelligent management controller sequentially reads the epitope information of the epitopes of the plurality of electric energy meters managed on the multi-path controller from epitope 1 to the maximum number of digits supported by the multi-path controller.
It should be noted that the epitope information includes data packet information of a corresponding epitope electric energy meter, and the data packet information includes: the electric energy meter comprises an electric energy meter address, an electric energy meter type, electric energy meter version information, electric energy data of the electric energy meter, instant information, a relay state and running state information.

S203, the intelligent management controller sends a 0 epitope read data request based on the communication bus, judges whether the communication bus responds to the request,
if the intelligent management controller inquires the response data, judging that the electric energy meter with the newly installed 0 meter position is accessed to the electric energy meter position of the centralized meter box, and entering step S204, otherwise, continuing to enter step S201;
s204, the multi-path controller executes a new cycle of epitope writing task, and after the newly installed electric energy meter obtains the effective epitope information written by the multi-path controller, the epitope number of the newly installed electric energy meter is updated and stored;
it should be noted that, when the multi-channel controller writes the epitope information into the electric energy meter corresponding to the epitope, the electric energy meter which originally stores the epitope information may actually write the same epitope information repeatedly, the electric energy meter with the newly installed 0 epitope may write a certain unique epitope information, and the epitope number of the newly installed electric energy meter may be updated to a non-0 epitope number, where the certain unique epitope information must be one corresponding epitope information from epitope 1 to the maximum epitope number supported by the multi-channel controller.
