Intelligent electric meter and circuit breaker automatic connection method and intelligent electric meter

Abstract

The invention provides an intelligent electric meter and circuit breaker automatic connection method, and belongs to the technical field of communication. The method comprises the steps that a circuitbreaker generates a first pairing feature code used for identifying the identity of the circuit breaker, the first pairing feature code is sent simultaneously in a reactive current mode and a wireless communication mode, and first pairing matching verification is achieved; after the first pairing matching verification succeeds, an intelligent electric meter generates a second pairing feature code, the second pairing feature code is sent to the circuit breaker in a wireless communication mode, and second pairing matching verification is achieved through the second pairing feature code returnedby the circuit breaker in a reactive current mode; and after the second pairing matching verification succeeds, it is determined that the circuit breaker is an external circuit breaker of the intelligent electric meter, and the intelligent electric meter and the circuit breaker are paired and connected. The reactive current mode and the wireless communication mode are combined, automatic pairingof the circuit breaker and the wireless intelligent electric meter is realized through two times of pairing matching verification, and the pairing efficiency and accuracy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for automatically connecting a smart meter and a circuit breaker and a smart meter. Background technique [0002] The external miniature circuit breaker of the ammeter is the key equipment to cooperate with the smart meter to realize the smart fee control function. The smart meter with a relatively large rated current generally uses a miniature circuit breaker to realize various fee control functions. The connection between the smart meter and the circuit breaker can be established through Bluetooth communication, and automatic pairing is the basis for establishing a connection between the circuit breaker and the smart meter. Any device that has never been paired (or has been paired but one of them has deleted the pairing relationship) cannot be established. connect. Usually, the electric meter installation site needs to scan and pair the electric meter and the ci...
