Embodiment Construction

[0029] The present invention will be further described with reference to the accompanying drawings.

[0030] refer to figure 1 , which is an automatic pairing method between a bluetooth circuit breaker and an electric energy meter disclosed in this embodiment, the MAC address at the time of delivery is set in the electric energy meter in advance, and the MAC address of itself is set in the bluetooth circuit breaker, and the following steps are also included:

[0031] Step S1, information acquisition: the Bluetooth circuit breaker is in the active mode and scans the electric energy meter device, and puts all the electric energy meter information in the meter box into the list.

[0032] Step S2, preliminary screening: firstly read the existing MAC address information in the electric energy meter, keep the unpaired electric energy meters, and exclude the paired electric energy meters. Since there are multiple energy meters in one meter box, some of them are already connected to ...

Abstract

The invention discloses an automatic pairing method for a Bluetooth circuit breaker and an electric energy meter, and relates to the technical field of circuit breakers and electric energy meters. Themethod is characterized in that the method comprises the steps of S1 acquiring information; S3 identifying modulated current waves: trying to pair the Bluetooth circuit breakers with the electric energy meters in the list one by one; enabling the Bluetooth circuit breaker to generate a current wave; enabling an electric energy meter connected with the Bluetooth circuit breaker to sample the samecurrent wave; synchronously reading the current information of the electric energy meter; once the read current information does not match the modulated current wave information, terminating the pairing of the Bluetooth circuit breaker , and then enabling the Bluetooth circuit breaker to try to be paired with the next electric energy meter until the electric energy meter which should be really paired is found, and enabling the Bluetooth circuit breaker to write the paired MAC address into the electric energy meter and initiate the reading of the state of the Bluetooth circuit breaker; and S4 switching the Bluetooth circuit breaker into a slave mode and connecting the Bluetooth circuit breaker with the electric energy meter. According to the invention, the corresponding electric energy meter can be found from the plurality of electric energy meters, and automatic pairing of the Bluetooth circuit breaker and the electric energy meter is realized.

Description

technical field [0001] The invention relates to the technical field of a circuit breaker and an electric energy meter, more specifically, it relates to an automatic pairing method for a bluetooth circuit breaker and an electric energy meter. Background technique [0002] With the promotion of the smart grid, the circuit breaker and some control devices can be wirelessly connected via bluetooth or wifi to reduce the number of wired connections or cancel wired connections. [0003] For example, in the prior art, a Chinese patent document with the authorized announcement number CN106373831B discloses a circuit breaker, including a switch body, and the connection between the switch body and the fee-controlled electric energy meter is realized by being provided with a remote control module, and the remote control module It is a bluetooth control module, and the bluetooth control module includes a bluetooth transmitter set in the electric energy meter and a bluetooth receiver set ...
