中文摘要:针对智能电表与表后断路器大多依赖人工掌机扫码进行配对，配对过程过度依赖人工，成本高，且容易发生误配对串户等问题，提出了面向新一代智能电表的微电流指纹自动配对技术。该技术通过在蓝牙断路器内置开关电容模块和编码电路，将配对特征码信息调制成无功电流信号，利用电力线传输至智能电表，并与蓝牙断路器广播发送的配对特征码信息进行比对，从而实现智能电表与表后断路器的自动配对。该配对过程无需依赖人工，极大地降低了人工成本，提高了配对的准确性。最后，实验验证了所提的微电流指纹自动配对技术的正确性和有效性。

Micro-current Fingerprint Automatic Matching Technology for New Generation Smart Meters

Abstract:In view of the problems of smart meters and post-meter circuit breakers mostly rely on manual handheld scanners for pairing. The pairing process relies too much on manual labor, which is costly and prone to mismatching. A micro-current fingerprint automatic matching technology for a new generation of intelligent meters is proposed. Through the built-in switched capacitor module and coding circuit in the Bluetooth circuit breaker, the paired signature information is modulated into a reactive current signal, which is transmitted to the smart meter by the power line, and compared with the paired signature information transmitted by the Bluetooth circuit breaker broadcast, so as to realize the automatic pairing between the smart meter and the post-meter circuit breakers. The pairing process does not need to rely on labor, which greatly reduces the labor cost and improves the accuracy of pairing. Finally, the correctness and effectiveness of the proposed micro-current fingerprint automatic matching technique are verified by experiments.
