Among these, the metering and non-metering parts must be strictly separated and are the core of many variations.
The metering part and the non-metering part of the method must be strictly separated, and the electric energy meter is required to adopt a double-core mode.

For example, when special electromagnetic working conditions or environmental changes occur, interface faults are caused, so that normal communication between modules cannot be achieved, and finally the whole electric energy meter runs.

As a possible implementation manner, after receiving the fault management right, the functional module may perform communication fault processing on the electric energy meter based on the fault processing method of the modular electric energy meter described in steps S101 to S103 and steps S201 to S205.
Therefore, the embodiment of the invention can monitor the occupancy rate of the communication port of each functional module in real time and determine the functional module with the fault management right of each functional module based on the occupancy rate of the communication port of each functional module. The functional modules with less communication port occupancy rate of each functional module hold the fault management right to process the communication faults of the electric energy meter, thereby realizing the optimal selection of the fault management right, ensuring the self-repairing capability of the communication faults among the modules of the electric energy meter and further improving the probability of the reliable and stable operation of the whole electric energy meter.

As a possible implementation manner, the management module may periodically send the communication state information to the metering module, so as to ensure that the metering module monitors the communication state of the management module in real time.
For example, when the management module is in normal communication, the management module may send communication state information representing that the communication is normal to the metering module.
For example, when the management module is in communication abnormality, the management module may send communication state information characterizing the communication abnormality to the metering module.
As a possible implementation manner, the metering module may periodically send a second request indicating the backhaul communication state to the management module, and the metering module receives a second response backhaul from the management module to determine whether the management module is in the normal communication state.
For example, if the second response indicates that the management module is communicating normally, the metering module may determine that the management module is in a normal communication state.
For example, if the second response indicates that the management module is in a communication abnormal state, the metering module may determine that the management module is in a communication abnormal state.
For example, if the metering module receives a first response, the metering module may determine that the management module is in a communication exception state.
And S302, if the management module is in a normal communication state, keeping the fault management right unchanged, and performing communication fault processing on the electric energy meter by the management module.
As a possible implementation manner, the management module may perform communication fault processing on the electric energy meter through the fault processing method of the modular electric energy meter described in steps S101 to S103 and steps S201 to S205.
And S303, if the management module is in the abnormal communication state, the metering module holds the fault management right and processes the communication fault of the electric energy meter.
As a possible implementation manner, if the management module is in a communication abnormal state, the metering module sends first indication information to the power supply module, where the first indication information is used for indicating the power supply module to reset the management module.
As a possible implementation manner, if the management module is in the abnormal communication state, the metering module sends second indication information to the plurality of functional modules, where the second indication information is used for indicating the plurality of functional modules to send the communication state information to the metering module.
Therefore, the embodiment of the invention can monitor the management module in real time through the metering module, ensures the self-repairing function of the electric energy meter when the management module has communication faults, further improves the self-repairing capability of the electric energy meter, and further improves the probability of reliable and stable operation of the whole electric energy meter.
