Pairing method and system of smart meter and Bluetooth circuit breaker based on identity authentication

Abstract

The invention discloses a pairing method and system of a smart electric meter and a bluetooth circuit breaker based on identity authentication. Quantum identity number, and return to the Bluetooth circuit breaker; at the same time, the quantum key distribution terminal receives the pairing message of the smart meter, and establishes the mapping relationship between the smart meter and the corresponding registered Bluetooth short circuit; the Bluetooth circuit breaker uses reactive current. The received quantum identity number is modulated and sent to the cable, and the quantum identity number is sent by Bluetooth broadcast; the smart meter demodulates the quantum identity number transmitted by the cable through sampling current data, and scans and broadcasts through the Bluetooth module; when the scanned bluetooth When the transmitted quantum ID is consistent with the quantum ID on the cable, a pairing message is sent to the quantum key distribution terminal. The invention has the advantages of high matching efficiency, safe data transmission and the like.

Description

technical field [0001] The invention mainly relates to the technical field of pairing of a circuit breaker and an electric energy meter, in particular to a method and system for pairing a smart electric meter and a Bluetooth circuit breaker based on identity authentication. Background technique [0002] The fee-controlled switch used in conjunction with the smart prepaid electricity meter still has obvious deficiencies in function, that is, the power can be automatically cut off after arrears, but the switching on after payment needs to be completed manually, which greatly increases the workload of the power supply company. Labor cost, although the built-in micro-relay in the smart prepaid meter can basically solve the problem of automatic closing of the fee-controlled switch after payment, but due to the small contact distance of the built-in micro-relay, creepage and flashing are prone to occur during the opening and closing process. network, etc., after long-term operatio...

Problems solved by technology

[0004] (1) The Bluetooth circuit breaker randomly generates a 16-digit pairing feature code, which cannot guarantee the uniqueness of each Bluetooth circuit breaker pairing feature code. The bluetooth circuit breaker, and then need to carry out secondary identification through the pairing feature code 2, select the actual circuit breaker from several bluetooth circuit breakers, which takes a long time;

[0005] (2) In the original pairing scheme, since the energy meter and the Bluetooth circuit breaker do not know their respective mac addresses at the initial stage, two broadcast interactions are required to ensure the address association between the energy meter and the Bluetooth circuit breaker, and the pairing efficiency is low;

[0006] (3) The existing scheme transmits data through the Bluetooth module, but the security of data transmission in the Bluetooth mode is extremely low, and the privacy of data transmission cannot be guaranteed
