the palm machine is used for scanning the two-dimensional codes of the electric energy meters and the two-dimensional codes of the circuit breakers to obtain authentication information of each electric energy meter and each circuit breaker; the authentication information is the matching relation between the electric energy meter and the circuit breaker;
the palm machine is also used for issuing the authentication information to each electric energy meter and each circuit breaker;
the electric energy meter is also used for sending a matching request signal to the circuit breaker corresponding to the authentication information;
the circuit breaker is also used for sending a matching response signal to the electric energy meter corresponding to the authentication information when receiving the matching request signal;
the electric energy meter is also used for establishing Bluetooth connection with the circuit breaker which sends the matching response signal to complete matching with the circuit breaker which sends the matching response signal.
8. The power bay control system of claim 2, wherein each power meter is further configured to send an error match signal to the collection master station when the target MAC address does not match the actual MAC address;
the acquisition master station is further used for inquiring whether the acquisition master station stores the standby matching information when receiving the error matching signal, and taking the standby matching information as the first matching information when the acquisition master station stores the standby matching information.
9. The power distribution room control system of claim 8, wherein the collection master station is further configured to issue an inspection task to the collection terminal to inspect the electric energy meter sending the mismatching signal when the collection master station does not store the standby matching information.
10. The power bay control system of claim 8, wherein the operating state of the power meter comprises: a to-be-matched state, a standby state and a connected state.
