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, In this paper, 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. |
